BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 represents a configuration example of a network system to which the present invention is applied. In this configuration example, servers 2-1, 2-2 and user apparatuses 3-1, 3-2 are connected to a network 1 configured by the Internet, a WAN (Wide Area Network), a LAN (Local Area Network) or the like. In the FIG. 1 example, although two servers 2-1, 2-2 (hereinafter, referred merely to as a server 2, where there is no need to individually distinguish these servers) and two user apparatuses 3-1, 3-2 (hereinafter, referred merely to as a user apparatus 3, where there is no need to individually distinguish these servers) are connected to the network 1, the number of these is arbitrary and may be three or more, respectively.

The server 2-1 provides preference information (preference information 401, hereinafter referred in FIG. 7) and the server 2-2 provides broadcast program information (EPG (Electric Program Guide) information) respectively to the user apparatus 3 through the network 1.

The user apparatus 3 is arranged within a user's household. The user apparatus 3-1 is configured by a video recording/reproducing unit 11, a display unit 12 and an antenna 13.

The video recording/reproducing unit 11, e.g. a hard-disk video-recorder, receives a broadcast wave through the antenna 13, and stores a signal obtained by demodulation to an auxiliary storage device 40 incorporated (see FIG. 2, hereinafter referred) and provides it to the rear-staged display unit 12 in order to make a display thereon. The display unit 12 is made by a television receiver or a monitor, for example.

Incidentally, although not shown, the user apparatus 3-2 also is configured similarly to the user apparatus 3-1.

The video recording/reproducing unit 11 is configured as shown in FIG. 2, for example. A tuner 31 demodulates a broadcast signal corresponding to a received broadcast wave of terrestrial-wave television broadcast wave, and outputs a video signal component and audio signal component to an encoder 32. In the terrestrial-wave television broadcast signal received by the antenna 13, there is included EPG information in the vertical blanking period thereof. The tuner 31 outputs the EPG information to an EPG acquisition module 34.

An encoder 32 encodes the video and audio signal inputted from the tuner 31 under the MPEG (Moving Picture Experts Group) scheme for example, and supplies and stores it to the auxiliary storage device 40 through a bus 52. The auxiliary storage device 40 is configured by a hard disk, a magnetic tape, a removable disk, a flash memory or the like.

The video and audio signal stored in the auxiliary storage device 40 is outputted through the bus 52 to a decoder 33 where it is decoded under the MPEG scheme and then supplied to the display unit 12. The encoder 32 and decoder 33, in the case not storing a received video and audio signal to the auxiliary storage device 40, outputs a signal outputted from the tuner 31 directly to the display unit 12.

The bus 52 is connected with a main storage device 39, e.g. of RAM (Random Access Memory), and a ROM (Read Only Memory) 38. To the main storage device 39, suitably stored is the data and parameter required for the CPU (Central Processing Unit) 35 to carry out various processes. The ROM 38 is stored with the program the CPU 35 is to execute.

The bus 52 is further connected with a network interface 37 for executing an interface process to the network 1.

The CPU 35 is connected to the bus 51, together with the encoder 32, decoder 33 and EPG acquisition module 34. This bus 51 is also connected with a main storage device 36 configured by a RAM or the like.

The video recording/reproducing unit 11 has a functional configuration centered on software, as shown in FIG. 3. A live broadcast reproducing section 61 makes a processing of a signal being received at that time by the tuner 31 or a signal inputted from a not-shown external input terminal. A recording title reproducing section 62 carries out a reproducing process of a program (title) stored in the auxiliary storage device 40. The recording control section 63 executes a recording process of signals to the auxiliary storage device 40. An application managing section 64 executes a monitor process in a start-up, end and operation state of a viewing-control application 68, a broadcast-program information display application 69 and a recording scheduling application 70.

The viewing-control application 68 takes control of the live-broadcast reproducing section 61, recording title reproducing section 62, recording title managing section 65 or broadcast-program information managing section 66, on the basis of an instruction from a user, to reproduce a signal being received or inputted at that time or reproduce a program stored in the auxiliary storage device 40. Meanwhile, the viewing-control application 68 controls the live-broadcast reproducing section 61, and appropriately looks up the broadcast program information stored in the broadcast program information managing section 66 when causing the tuner 31 to receive a broadcast program of a channel designated from the user. Furthermore, the viewing-control application 68 takes control of the recording title reproducing section 62, and appropriately looks up the program management information stored in the recording title managing section 65 when reproducing the program stored in the auxiliary storage device 40.

The broadcast-program information display application 69 looks up the broadcast program information (EPG information) stored in the broadcast-program information managing section 66, and causes the display unit 12 to display broadcast-program information. The recording scheduling application 70 executes a recording scheduling process and generates user's preference information (preference information about broadcast programs), on the basis of an instruction from the user. At this time, the recording scheduling application 70 looks up the broadcast program information stored in the broadcast-program managing section 66, as required. Meanwhile, the recording scheduling application 70, when recording is scheduled on the basis of an operation from the user, takes control of the recording schedule managing section 67 to execute a recording scheduling process.

The recording title managing section 65 manages the information about programs (titles) stored in the auxiliary storage device 40. The broadcast-program information managing section 66 manages the broadcast program information acquired by the EPG acquisition module 34. The recording schedule managing section 67 takes control of the recording control section 63 and executes a recording scheduling process, on the basis of the request from the program-recording scheduling application 70 or the auto picture-recoding schedule control section 71.

The auto picture-recoding schedule control section 71 carries out a recording scheduling process on the basis of the preference information (preference information 401 in FIG. 17, hereinafter referred) acquired from the server 2-1. The network communicating section 72 communicates with the servers 2-1, 2-2 through the network 1, to acquire preference information (preference information 401 in FIG. 7, hereinafter referred) and broadcast program information.

The server 2-1 is configured as shown in FIG. 4, for example. In FIG. 4, a CPU (Central Processing Unit) 221 carries out various processes according to the program stored in a ROM (Read Only Memory) 222 or the program loaded from a storage section 228 to a RAM (Random Access Memory) 223. To the RAM 223, suitably stored is the data required for the CPU 221 to execute various processes.

The CPU 221, the ROM 222 and the RAM 223 are mutually connected through a bus 224. This bus 224 is also connected with an input/output interface 225.

The input/output interface 225 is connected with an input section 226 configured by a keyboard, a mouse or the like, an output section 227 configured by a display, such as a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display), as well as a speaker, a storage section 228 configured by a hard disk or the like, and a communicating section 229 configured by a modem or the like. The storage section 228 is stored with preference information (preference information 401 in FIG. 7, hereinafter referred) to be provided to the user apparatus 3. The communicating section 229 implements a communication process through the network 1 including the Internet.

The input/output interface 225 is also connected with a drive 230, as required, to be suitably loaded with a removable media 231, such as a magnetic disk, an optical disk, a magnetooptical disk or a semiconductor memory. The computer program read therefrom is installed to the storage section 228, as required.

Incidentally, although showing is omitted, the server 2-2 is basically similar in configuration to the server 2-1 shown in FIG. 4.

FIG. 5 is a block diagram showing a functional configuration of the server 2-1.

A network communicating section 301 communicates with the user apparatus 3 through the network 1, to supply it with preference information (preference information 401 hereinafter referred). Also, it receives the preference information sent from the user apparatus 3 and the user ID sent from the user apparatus 3, through the network 1.

A register managing section 302 stores the information acquired by controlling the network communicating section 301 to a customer database 304 or preference information database 305, and acquires the information stored in the customer database 304 or preference information database 305, outputting it through the network communicating section 301. Meanwhile, the register managing section 302 registers the user ID acquired from the user apparatus 3 through the network communication section 301. A screen managing section 303 manages a trust registering screen (FIG. 9 hereinafter referred) on the basis of the user ID under management of the register managing section 302.

Referring now to a flowchart of FIG. 6, explained is a preference information preparing process by the video recording/reproducing unit 11 of FIG. 3. Incidentally, this process is started when the user inputs an operation as liking a predetermined program (operation expressing to have a preference for a predetermined program) to the video recording/reproducing unit 11.

At step S1, the recording scheduling application 70, when the user operates to have a preference for a predetermined program, acquires a signal based on that operation. Such operations include a scheduling for recording or a protection, for example. For example, when the user operates to schedule for recording a certain program, the recording scheduling application 70 acquires it and executes a recording scheduling process.

At step S2, the auto recording schedule control section 71 acquires a title, detail information, genre, airing time zone and broadcast station of the program (program scheduled for recording by the process of step S1), from the broadcast program information (EPG information) stored in the broadcast-program information managing section 66. Namely, the broadcast-program information managing section 66 is stored with broadcast program information (EPG information) as shown, for example, in FIG. 17 hereinafter referred. Based on it, this process is to be executed.

At step S3, the auto recording schedule control section 71 extracts a preference keyword from the title or detail information acquired by the process of step S2 (extracted preference keyword provides keyword preference information 402 in FIG. 7 hereinafter referred). For example, in the case a particular public entertainer's name is included in the title or detail information, it will be extracted.

At step S4, the auto recording schedule control section 71 holds the preference keyword extracted by the process of step S3 and the information of genre, airing time zone and broadcast station acquired by the process of step S2, as preference information.

By the process of FIG. 6, started is an acquisition of preference information about a broadcast program depending upon the user's operation as liking a predetermined program (operation such as scheduling of recording, protection, etc.). Meanwhile, depending upon the user's operation as liking a predetermined program, the information of a preference keyword, genre, airing time zone and broadcast station extracted from the program detail information is acquired as preference information from the broadcast program information.

FIG. 7 represents an example of the preference information 401 held by the process of FIG. 6.

As shown in FIG. 7, the preference information 401 is configured by preference information about a broadcast program, including keyword preference information 402, genre preference information 403, broadcast station preference information 404 and time-zone preference information 405. Naturally, the preference information (keyword preference information 402, genre preference information 403, broadcast station preference information 404 and time-zone preference information 405) constituting the preference information 401 is not limited to these. The auto recording schedule control section 71, by looking up the preference information, can make a scheduling for recording programs to the taste.

The keyword preference information 402 is configured by “keyword name”, “update” and its “keyword name” point. In the FIG. 7 example, the first “keyword name” in the keyword preference information 402 is given “Yamada Ichiroh”, and the time “update” that the “keyword name” has been updated is “2002.1.3 10:03:45”, whose “keyword name” point is “30”. Meanwhile, the second “keyword name” in the keyword preference information 402 is given “Tanaka Hanako”, and the time “update” that the “keyword name” has been updated is “2002.1.3 10:03:45”, whose “keyword name” point is “20”. Furthermore, the third “keyword name” in the keyword preference information 402 is given “baseball”, and the time “update” that the “keyword name” has been updated is “2002.1.3 10:03:45”, whose “keyword name” point is “10”. Meanwhile, the fourth “keyword name” in the keyword preference information 402 is given “Sunday Theater”, and the time “update” that the “keyword name” has been updated is “2002.1.3 10:03:45”, whose “keyword name” point is “25”.

The “keyword name” point is greater in value with higher user's preference degree for the keyword corresponding to “keyword name”. Incidentally, in the FIG. 7 example, although the “keyword name” point is a positive value, it can be given a negative value. For example, in the case there is a keyword the user does not prefer (dislike), the “keyword name” can be held as a negative value in the preference information 401. Naturally, when the “keyword name” point has a negative value greater (smaller value) in absolute value, it is a keyword less preferred (more disliked) by the user.

In the FIG. 7 example, as the “keyword name” in the keyword preference information 402, the “keyword name” in the keyword preference information 402 preferred the most by the user is “Yamada Ichiroh” (because the keyword name point is 30″, or the greatest value).

The genre preference information 403 is configured by “genre id”, “update” and its “genre id” point. In the FIG. 7 example, the first “genre id” in the genre preference information 403 is “1” (e.g. “1” is a value corresponding to sport). The time “update” that “genre id” has been updated is “2002.1.3 10:03:45”, whose “genre id” point is given “23”. Meanwhile, the second “genre id” in the genre preference information 403 is “3” (e.g. “3” is a value corresponding to drama) and the time “update” the “genre id” has been updated is “2002.1.3 10:03.45”, whose “genre id” point is given “−10”.

The “genre id” point is greater in value with higher user's preference degree. Incidentally, when the “genre id” point has a negative value, the genre corresponding to the “genre id” is a genre the user does not prefer (dislike).

In the FIG. 7 example, as “genre id” in the genre preference information 403, the “genre id” preferred the most by the user is “1” (e.g. “1” is a value corresponding to sport) wherein (because the “genre point” is “23”, or the greatest value) the “genre id” not preferred the most (disliked) by the user is “3” (e.g. “3” is a value corresponding to drama).

The information corresponding to broadcast station preference information 404 is configured by “station id”, “update” and its “station id” point. In the FIG. 7 example, the first “station id” in the broadcast station preference information 404 is “1” (e.g. “1” is an ID corresponding to channel 1), wherein the time “update” the “station id” has been updated is “2002.1.310:03:45” and its “station id” point is given “23”. Meanwhile, the second “station id” in the broadcast station preference information 404 is “5” (e.g. “5” is an ID corresponding to channel 5), wherein the time “update” the “station id” has been updated is “2002.1.3 10:03:45” and its “station id” point is given “−10”.

In also the “station id” point, the greater value is taken with higher user's preference degree. Incidentally, in the case the “station id” point is a negative value, the broadcast station corresponding to the “station id” is a broadcast station the user does not prefer (dislike).

In the FIG. 7 example case, as a “station id” in the broadcast station preference information 404, the “station id” preferred the most by the user is “1” (e.g. “1” is an ID corresponding to channel 1) wherein (because the “station id” point is “23”, or the greatest value,) the “station id” not preferred (disliked) the most by the user is “5” (e.g. “5” is an ID corresponding to channel 5).

The information corresponding to the time-zone preference information 405 is configured by “time_zone id”, “update” and its “time_zone id” point. In the FIG. 7 example, the first “time_zone id” in the time-zone preference information 405 is “0” (e.g. “0” is a value corresponding to from 0:00 to 1:00) wherein the time “update” that the “time_zone id” has been updated is given “2002.1.3 10:03:45” and its “time_zone id” point is “50”. Meanwhile, the second “time_zone id” in the time-zone preference information 405 is “2” (e.g. “2” is a value corresponding to from 2:00 to 3:00) wherein the time “update” that the “time_zone id” has been updated is given “2002.1.3 10:03:45” and its “time zone id” point is “−10”. Furthermore, the third “time_zone id” in the time-zone preference information 405 is “4” (e.g. “4” is a value corresponding to from 4:00 to 5:00) wherein the time “update” that the “time_zone id” has been updated is given “2002.1.3 10:03:45” and its “time_zone id” point is “−20”. Meanwhile, the fourth “time_zone id” in the time-zone preference information 405 is “8” (e.g. “8” is a value corresponding to from 8:00 to 9:00) wherein the time “update” that the “time_zone id” has been updated is given “2002.1.3 10:03:45” and its “time_zone id” point is “23”.

In also the “time_zone id” point, the higher the preference degree, the greater the value is taken. Incidentally, when the “time_zone id” point has a negative value, the time zone corresponding to the “time_zone id” is given a time zone the user does not prefer (dislike).

In the FIG. 7 example, as the “time_zone id” in the time-zone preference information 405, the “time_zone id” preferred the most by the user is “0” (e.g. “0” is a value corresponding to from 0:00 to 1:00) wherein (because the “time_zone id” point is “50”, or the greatest value,) the “time_zone id” not preferred (disliked) the most by the user is “4” (e.g. “4” is a value corresponding to 4:00 to 5:00).

The information in the above is stored as user's preference information 401 in the user apparatus 3. The user on the user apparatus 3, when holding preference information in the above manner, registers it to the server 2-1 and allows the same to be used by a friend or the like.

Referring now to a flowchart of FIG. 8, explained is a process for registering the preference information the user on the user apparatus 3-2 has prepared (held) by himself/herself (user's preference information) to the server 2-1. Incidentally, this process is commenced when user registration is instructed by the user.

At step S21, the auto recording schedule control section 71 acquires the preference information 401 (e.g. preference information 401 in FIG. 7) to be registered to the server 2-1. This preference information 401 has been prepared by executing the process shown in the flowchart of FIG. 6, by user's scheduling of recording or the like.

At step S22, the auto recording schedule control section 71 takes control of the network communicating section 72, to access the server 2-1 through the network 1. The server 2-1 accepts the access from the user apparatus 3-2 (step S41 in FIG. 10 hereinafter referred) and sends a trust registering screen (step S42 in FIG. 10 hereinafter referred). The user apparatus 3-2 receives the trust registering screen (FIG. 9 hereinafter referred) sent from the server 2-1.

At step S23, the auto recording schedule control section 71 causes the display unit 12 to display the trust registering screen sent (step S42 in FIG. 12) by the server 2-1, through the use of the broadcast-program information display application 69. An example of the trust registering screen is shown in FIG. 9.

In FIG. 9, there is displayed a message “Input user ID of user of trust and press decide”, wherein displayed is a box to input a user ID. The user inputs a user ID of another user by whom his/her own preference information is desirably utilized, and operates a decide button 501.

Referring back to FIG. 8, the auto recording schedule control section 71 at step S24 acquires a to-be-registered user ID. Specifically, when the user inputs a user ID on the screen shown in FIG. 9 and selects the decide button 501, the auto recording schedule control section 71 acquires a user ID inputted. In the present example, it is assumed that the user who is to execute this process is a user at the user apparatus 3-2 while the user to be registered is a user at the user apparatus 3-1 (i.e. the user ID to be registered is a user ID of the user on the user apparatus 3-1). This means that the user apparatus 3-2 allows to provide the preference information to the user ID to be registered. Accordingly, the user who is to utilize this service is required registered himself/herself to the server 2-1 and assigned with a user ID in advance.

At step S25, the auto recording schedule control section 71 sends the preference information 401 acquired by the process of step S21 and the user ID (user ID of the user at the user apparatus 3-1, in the present example case) acquired by the process of step S24, to the server 2-1. The server 2-1 receives and registers it (steps S43 and S44 in FIG. 10 hereinafter referred).

Referring now to a flowchart of FIG. 10, explained is a user registering process on the server 2-1 corresponding to the process on the user apparatus 3-2 of FIG. 8. Incidentally, this process is commenced when accessed from the user apparatus 3-2.

At step S41, the network communicating section 301 accepts an access (step S22 in FIG. 8) from the user apparatus 3 (user apparatus 3-2 in the present case).

At step S42, the register managing section 302 reads out a trust registering screen (FIG. 9) under management of the screen managing section 303, and sends it to the user apparatus 3 through the network communicating section 301. Specifically, it sends the data of a trust registering screen shown in FIG. 9 noted above. The user apparatus 3 (user apparatus 3-2) receives and displays this (step S23 in FIG. 8), and acquires a to-be-registered user ID (user apparatus 3-1 in the present example) and preference information 401 (preference information of the user on the user apparatus 3-2), thus sending it to the server 2-1 (step S25 in FIG. 8).

Consequently, at step S43, the register managing section 302 receives the preference information 401 (preference information of the user on the user apparatus 3-2) and to-be-registered user ID, through the network communicating section 301.

At step S44, the register managing section 302 acquires the preference information 401 (preference information of the user on the user apparatus 3-2) and user ID to be registered, and registers them to the preference information database 305. Specifically, it stores the preference information 401 to the preference information database 305 and the user ID (ID of the user apparatus 3-1) (user ID specifying the destination the program information is to be provided) to customer database 304. Due to this, in the present case, registration is made that the user having the trust of the user on the user apparatus 3-2 is a user of the user apparatus 3-1.

At step S45, the register managing section 302 takes control of the network communicating section 301, to notify the registered user (user apparatus 3-1 in the present example case) of a fact registration has been made from the user apparatus 3 (user apparatus 3-2 in the present example case).

In this manner, preference information is registered by the process of FIGS. 8 and 10.

Referring now to a flowchart of FIG. 11, explained is a process of the user apparatus 3 (e.g. user apparatus 3-1) to be executed correspondingly to the process of the step S45 of FIG. 10. Incidentally, this process is commenced when notification is made from the server 2-1 to the user apparatus 3 (user apparatus 3-1) haven by the user registered.

At a step S61, the user apparatus 3 (user apparatus 3-1 in the present example case) accepts an access from the server 2-1 (step S45 in FIG. 10).

At step S62, the user apparatus 3 (user apparatus 3-1 in the present case) receives a notification from the server 2-1. This notification contains the information representing that preference information (preference information of the user on the user apparatus 3-2) has been registered by the user apparatus 3-2 having executed the process of FIG. 8. By receiving this notification, the user on the user apparatus 3-1 is allowed to know the fact that preference information (preference information of the user on the user apparatus 3-2) has been registered by another user apparatus (user apparatus 3-2 in this case).

Referring now to a flowchart of FIG. 12, explained is a preference information acquiring process by the user apparatus 3. Incidentally, this process is commenced when instructed to make a scheduling of recording by the user possessing the user apparatus 3 (e.g. user apparatus 3-1).

At step S81, the network communicating section 72 accesses the server 2-1 on the basis of an instruction by the user. The server 2-1 accepts the access (step S111 in FIG. 14 hereinafter referred). In the case determined that registration has been made as a destination of provision of the preference information (in the case rendered YES in step S112 in FIG. 14 hereinafter referred), sent is a select screen for selecting one from a plurality of pieces of user apparatus 3 preference information (step S113 in FIG. 14 hereinafter referred).

Consequently, at step S82, the network communicating section 72 receives the select screen for selecting one from a plurality of pieces of user apparatus 3 preference information sent from the server 2-1. The auto recording schedule control section 71 takes control of the broadcast-program display application 69, and causes the display unit 12 to display a select screen for selecting one from a plurality of pieces of user apparatus 3 preference information.

At this time, a display example to be displayed on the display unit 12 is shown in FIG. 13. In FIG. 13, there is displayed a message “Preference Information List by Person Trusting You. Select Like List of Preference Information”. In the below of the message, there are arranged, for selection, User X button 521, User B button 522 and User C button 523. The user selects any one from the User X button 521, the User B button 522 and the User C button 523. Incidentally, the User X button 521, the User B button 522 and the User C button 523 displayed in FIG. 13 are of the user names of the user IDs registered together by the foregoing step S25 of FIG. 8 and step S44 of FIG. 10.

At step S83, the auto recording schedule control section 71 accepts a piece of designation information for designating a predetermined one out of a plurality of pieces of preference information, on the basis of user's operation. For example, in the case that, by the user, the User B button 522 is selected on the FIG. 13 screen displayed on the display unit 12 by the process of step S82, acquired is designation information representing that the User B button 522 has been designated.

At step S84, the network communicating section 72 sends the designation information on the designated preference information (designation information acquired by the process of step S83) to the server 2-1. In the case that the designation information representing that the User B button 522 has been designated by the process of step S83, the user apparatus 3 sends the server 2-1 the designation information representing that the User B button 522 has been designated. The server 2-1 receives this (step S114 in FIG. 14 hereinafter referred), and sends preference information to the user apparatus 3 (step S115 in FIG. 14 hereinafter referred). In this case, the User B sends the preference information previously registered in the server 2-1 (preference information database 305 in the server 2-1).

Consequently, at step S85, the auto recording schedule control section 71 receives the preference information (e.g. preference information 401 in FIG. 7) sent from the server 2-1, through the network communicating section 72. The recording schedule managing section 67 stores it to the preference information database (auxiliary storage device 40) internally provided. This preference information is preference information corresponding to the designated designation information sent by the process of step S84. In this case, because of the preference information corresponding to the designation information representing that the User B button 522 has been designated, it is preference information previously registered by the User B.

At step S86, the recording schedule managing section 67 makes a recording scheduling on the basis of the preference information received and stored by the process of step S85. Namely, scheduling of recording is made for the program designated by the stored preference information so that recording operation can be started at a predetermined time.

Referring now to a flowchart of FIG. 14, explained is a preference information acquiring process of the server 2-1 corresponding to the process of FIG. 12 to be executed by the user apparatus 3. Incidentally, this process is commenced when accessed from the user apparatus 3 (user apparatus 3-1, in the present case) by the process of step S81 of FIG. 12.

At step S111, the network communicating section 301 accepts an access (step S81 of FIG. 12) from the user apparatus 3. For example, it accepts an access from the user apparatus 3-1.

At step S112, the register managing section 302 determines whether or not the user apparatus 3 accessed (user apparatus 3-1, in the present example case) has been registered as a providing destination of preference information. Specifically, the register managing section 302 looks up the customer database 304 and determines whether or not the user apparatus 3 (user apparatus 3-1, in the present example case) has been registered as a providing destination of preference information. In the case determined that the user apparatus 3 (user apparatus 3-1, in this example case) has been registered as a providing destination of preference information, the process proceeds to step S113, to send a select screen for selecting one from a plurality of pieces of user apparatus 3 preference information.

The user apparatus 3 receives those and displays a select screen for selecting one from a plurality of pieces of user apparatus 3 preference information (step S8 in FIG. 12), thereby prompting for designation, whereby it sends designation information about designated preference information (step S84 in FIG. 12). In this example case, sent is the designation information representing that the User B button 522 has been designated.

At step S114, the network communicating section 301 receives the designation information about designated preference information from the user apparatus 3-1. The register managing section 302 reads the preference information of the program (e.g. preference information 401 in FIG. 7) from the preference information database 305 on the basis of the designation information. In this example case, received is the designation information representing that the user B button 522 has been designated, based on which the preference information registered by the User B is read out.

At step S115, the register managing section 302 sends the preference information (e.g. preference information 401 in FIG. 7) read out by the process of step S114, to the user apparatus 3 through the network communicating section 301. This preference information is received by the user apparatus 3, based on which a recording scheduling process is implemented (step S85, S86 in FIG. 12).

After the process of step S115 or in the step of S112, in the case of a determination that not registered as a destination of providing preference information, the process is terminated.

Incidentally, it is also possible to previously send the preference information of all the other users registered by the process of the step S113. In this case, because the user apparatus 3 itself can select required preference information, the process of step S114, S115 can be omitted. Meanwhile, in also the user apparatus 3, the process of step S84, S85 in FIG. 12 is omitted. However, in this case, there is an increase in amount of the data to be communicated.

By the process of FIGS. 12 and 14, the user apparatus 3 acquires from the server 2-1 a select screen for selecting one from a plurality of pieces of another user apparatus 3 preference information, and sends a selected piece of designation information on preference information to the server 2-1. From the server 2-1, received is preference information based on the designation information thereby carrying out a recording scheduling. This makes it possible to implement a scheduled recording on the basis of the preference information by another user apparatus 3. The user is allowed to share the same program with another user by providing preference information to the other user. Meanwhile, in the case to utilize the preference information of from another user, it is possible to omit the labor and time for preparing preference information by himself/herself.

The above process, if summarized, is as follows. Namely, as shown in FIG. 15, the customer database 304 and the preference information database 305 are held in the server 2-1. The customer database 304 is stored with the customer data of the user apparatus 3-1 and user apparatus 3-2. This can restrict the users who are allowed to use preference information. The user apparatus 3-2 supplies the preference information prepared by itself (e.g. preference information prepared by the process of FIG. 6) to the server 2-1 through the network 1. The server 2-1 registers this to the preference information database 305. By receiving a notification of preference information from the server 2-1 or voluntarily at a predetermined timing as required, when the user apparatus 3-1 accesses the server 2-1, the server 2-1 sends the preference information prepared by the user apparatus 3-2 (user registered in the customer database 304) (step S113 in FIG. 14).

The user apparatus 3-1 designates the preference information prepared by the registered user apparatus 3 (user apparatus 3-2, in the FIG. 15 example case) (in the case that preference information is registered by a plurality of users, this is designated), designated designation information is sent to the server 2-1 (step S84 in FIG. 12).

The server 2-1 receives this and acquires the preference information 611 stored in the preference information database 305 and corresponding to the designated information (e.g. preference information of the user apparatus 3-2), sending it to the user apparatus 3-1 through the network 1. The user apparatus 3-1 receives this and causes the auto recording schedule control section 71 to execute a recording process (recording scheduling) based on the preference information.

Incidentally, the manager on the server 2-1 can impose charge for the service provision as the above on the user of user apparatus 3 as required, to gain profits.

Meanwhile, the user ID may be plurality that are to be acquired by the auto recording schedule control section 71 at the step S24 in FIG. 8. In the case the auto recording schedule control section 71 is arranged to acquire user IDs (destination-of-provision information) in plurality at the step S24, then acquired preference information and a plurality of users (destinations of provision) are registered at step S44 in FIG. 10. This makes it possible to provide the same preference information to the plurality of users (destinations of provision).

As in the above, the user apparatus 3 acquires preference information through the server 2-1 and causes the auto recording schedule control section 71 to carry out a recording scheduling process. Also, it acquires the preference information prepared by the user himself/herself and causes the auto recording schedule control section 71 to carry out a recording schedulinq process. Once this setting (selection) is done by the user, scheduling of recording is automatically effected as explained in the next.

Referring now to a flowchart of FIG. 16, explained is a recording scheduling process to be automatically effected on the basis of preferential information by the auto recording schedule control section 71. Incidentally, the process shown in the FIG. 16 flowchart is periodically executed at a predetermined time interval previously set.

At step S131, the auto recording schedule control section 71 selects one piece of broadcast program information from the stored broadcast program information (EPG information) in an amount of two days, for example. As noted above, the EPG information is acquired by the EPG acquisition module 34 and placed under management of the broadcast-program information managing section 66. Specifically, the EPG information is in storage by the auxiliary storage device 40.

FIG. 17 represents an example of such EPG information (broadcast program information). Incidentally, this FIG. 17 example represents one program of broadcast program information. The auxiliary storage device 40 is stored with the broadcast program information of the nearest program to be aired for two days from the current time, for example.

In the FIG. 17 example, the broadcast station to air the program is “TV Japan”, whose date to air is Mar. 26, 2002. Meanwhile, this program has a broadcast start time of 17:00 and an end time of 18:00. Furthermore, this program is variety in genre, having a program title of “News 17”. Furthermore, there is described, as detail information, information including “Premier Resigned, Yen's Depreciation Inching . . .”.

In the process of step S131, selected herein is one program of broadcast program information as shown in FIG. 17, for example.

Next, at step S132, the auto recording schedule control section 71 acquires a preference value corresponding to the genre of the broadcast program information from the preference information and adds it to the preference value of the relevant program. Namely, in the case the genre of the broadcast program information selected by the process of the step S131 falls under the genre preference information 403 of the preference information 401, the auto recording schedule control section 71 adds the preference value to the preference value of the relevant program (broadcast program information selected by the process of the step S131).

The preference information to be used herein is the stored preference information transferred from the other user apparatus 3 in the process of step S85 of FIG. 12 or the preference information registered and held by executing the process shown in the flowchart of FIG. 6 by the user apparatus 3 itself.

At step S133, the auto recording schedule control section 71 acquires a preference value corresponding to the airing time zone of the broadcast program information from the preference information and adds it to the preference value of the relevant program. Namely, in the case the airing time zone of the broadcast program information selected by the process of the step S131 falls under the time-zone preference information 405 of the preference information 401, the auto recording schedule control section 71 adds the preference value to the preference value of the relevant program (broadcast program information selected by the process of the step S131).

At step S134, the auto recording schedule control section 71 acquires a preference value corresponding to the broadcast station of the broadcast program information from the preference information and adds it to the preference value of the relevant program. Namely, in the case the broadcast station of the broadcast program information selected by the process of the step S131 falls under the broadcast-station preference information 404 of the preference information 401, the auto recording schedule control section 71 adds the preference value to the preference value of the relevant program (broadcast program information selected by the process of the step S131).

At step S135, the auto recording schedule control section 71, if a keyword existing in the preference information is contained in the title keyword of the broadcast program information, adds the preference value of that keyword to the preference value of the relevant program. Namely, in the case the keyword of the broadcast program information selected by the process of the step S131 is contained in the keywords existing in the keyword preference information 402 of the preference information 401, the auto recording schedule control section 71 adds the preference value to the preference value of the relevant program (broadcast program information selected by the process of the step S131).

The process of the steps S132 to S135 sets a preference value of one piece of broadcast program information selected by the process of the step S131 (preference values are added by the respective steps, and the preference values of after the process of step S135 provide preference values of this broadcast program information).

At step S136, the auto recording schedule control section 71 determines whether or not all the pieces of broadcast program information (EPG information) have been selected. In the case determined that all the pieces of broadcast program information have not been selected yet (in the case there is a program having not been selected), the process returns to the step S131 where the broadcast program information of the next one program is selected, to execute the process of steps S132 and the subsequent similarly to the foregoing case.

In the case determined at step S136 that all the pieces of broadcast program information have been selected (in the case determined that the broadcast program information in an amount of two days has been selected), the process proceeds to step S137. The auto recording schedule control section 71 takes control of the recording schedule managing section 67, to make an addition in the higher order of program preference value to the recording schedule list up to the upper limit in the amount of recording schedule (make a recording scheduling process). Thereafter, the process is terminated.

Incidentally, the auto recording schedule control section 71, in the case the information registered in the preference information 401 includes negative one in point value, may exclude the program from a subject of search or may add a negative point of preference value. In the FIG. 7 example case, in the case that there is included one having a “genre id” “3” in the genre preference information 403, a “station id” of “5” in the broadcast station preference information 404, a “time_zone id” of “2” in the time zone preference information 405 or a “time_zone id” of “4” in the time zone preference information 405 is included in each broadcast program (e.g. FIG. 17) selected by the process of step S132, the program is excluded from the subject of search or added by a negative point of preference value.

As in the above, the auto recording schedule control section 71 causes the recording schedule managing section 67 to prepare a recording schedule list as shown in FIG. 18.

In the FIG. 18 example, there is registered airing date, broadcast station, airing start time and airing end time of the programs to be picture-recorded. For example, there is recorded a program to be aired at 16:00:00 to 16:30:00 on 2002, Jul. 1, by the broadcast station “TV Japan”, as a program scheduled for recording.

This recording schedule list is automatically prepared by mere user's registration of preference information or selecting operation. Accordingly, the user is not forced by an excessive burden in preparing the recording schedule list. Also, it is possible to automatically carry out a scheduling for recording matched to other users registered or selected.

Incidentally, of course, it is possible for the user to individually designate predetermined programs through the recording scheduling application 70 and register those to the recording schedule list.

In case a recording schedule list is prepared as in the above, the recording schedule managing section 67 executes a recording process on scheduled programs. Referring now to a flowchart of FIG. 19, explained is a recording process on scheduled programs. Incidentally, the process shown in the flowchart of FIG. 19 is to be periodically executed at a constant time interval.

At step S151, the recording schedule managing section 67 determines whether all the programs scheduled in the recording schedule list have been searched or not. In the case there is a scheduled program having not searched, the process proceeds to step S152 where the recording schedule managing section 67 extracts one program from the recording schedule list. At step S153, the recording schedule managing section 67 reads out the airing date and time of the program extracted in the process of step S152. For example, in the case that the program shown at number 1 in FIG. 18 is extracted by the process of step S152, its airing date and time “Jul. 1, 2002, 16:00:00” is read out as an airing date and time in the process of step S153.

At step S154, the recording schedule managing section 67 reads out the current date and time from the incorporated timer and determines whether or not the airing date and time read out in the process of step S153 is within a reference time from the current date and time. The reference time is a comparatively short time, e.g. 30 seconds or 1 minute. This reference time is determined taking account of a time required from instructing control through the recording control section 63 to actually starting a recording process.

In the case that the airing date and time is determined not within the reference time from the current date and time, the process returns to the step S151, to repeatedly execute the subsequent process.

For example, in case the current date and time is “Jul. 1, 2002, 12:00:00”, the current date and time is four hours before the airing date and time and hence not determined within the reference time. The process returns to the step S151, again making a determination process whether all the scheduled programs have been searched or not. In the present case, because all the programs have not yet been searched, the process proceeds to step S152 where the next one program is extracted. For example, the program shown at number 2 in FIG. 18 is extracted. At step S153, the airing date and time at number 2 is read out as “Jul. 1, 2002, 17:30:00”.

At step S154, it is determined whether or not the airing date and time is within a reference time from the current date and time. In case not within the reference time, the process returns to step S151, to repeatedly execute the subsequent process.

For example, in the case that the program at number 1 is selected and the current date and time is “Jul. 1, 2002, 15:59:30”, the airing date and time “Jul. 1, 2002, 16:00:00” is within 30 seconds from the current date and time “Jul. 1, 2002, 15:59:30” (within the reference time). Accordingly, it is determined at step S154 that the airing date and hour is within a reference time from the current date and time. In this case, the process proceeds to step S155 where the recording schedule managing section 67 takes control of the recording control section 63 to receive the program now being concerned. In this case, the broadcast radio wave of broadcast station TV Japan is caused received by the tuner 31.

At step S156, the recording schedule managing section 67 takes control of the recording control section 63 to store the program received by the process of step S155 to the auxiliary storage device 40.

Namely, the video and audio signals received at this time by the tuner 31 are supplied to the encoder 32 where it is encoded under the MPEG scheme and then supplied to and stored in the auxiliary storage device 40.

At step S157, the recording schedule managing section 67 determines whether the program is over or not by comparing between the airing end time of the program now under execution of recording process and the current date and time. In the case the program is not yet over, end is waited for. In the case the program is over, the process proceeds to step S158 where the recording schedule managing section 67 takes control of the recording control section 63 to terminate the recording process onto the auxiliary storage section 40. Also, at step S159, the recording schedule managing section 67 takes control of the recording control section 63 to terminate the program reception process by the tuner 31.

At step S160, the recording schedule managing section 67 deletes the program now completed in recording from the recording schedule list.

At step S151, in case it is determined that all the programs scheduled have been searched, the process of the steps S152 to S160 is skipped over to end the process.

The above process is executed at a constant time interval, to automatically picture-record the programs registered in the recording schedule list sequentially to the auxiliary storage device 40.

Incidentally, the recording schedule list shown in FIG. 18 can be arranged by sorting in the order of airing date and time. By doing so, the program first extracted by the process of step S152 could have the earliest airing date and time. In the case that its airing date and time is determined not within a reference time from the current date and time, all the remaining programs are resultingly not within the reference time from the current date and time. Accordingly, it is possible to omit the determination process concerning those programs.

After the program has been recorded to the auxiliary storage device 40 in the above manner, the recording title managing section 65 registers and manages the information about the title, airing date and time, etc. of the program picture-recorded.

When the user instructs to reproduce the picture-recorded program through the viewing-control application 68, the viewing-control application 68 looks up the management information in the recording title managing section 65 and reads out the program title picture-recorded in the auxiliary storage device 40, causing the display unit 12 to display it. When the user looks the display and selects a program to be reproduced, the viewing-control application 68 instructs the recording title reproducing section 62 to reproduce the program. The recording title reproducing section 62 reproduces the instructed program from the auxiliary storage device 40. The video and audio data reproduced from the auxiliary storage device 40 is inputted to the decoder 33 where it is decoded under the MPEG scheme, followed by being outputted to and displayed on the display unit 12.

By the above process, the user apparatus 3 acquires the preference information prepared by the registered user and causes the auto recording schedule control section 71 to carry out a recording process. The auto recording schedule control section 71 causes the recording schedule managing section 67 to prepare a recording schedule list (FIG. 18) and carry out a recording process. This allows for exchanging preference information at between the terminals (user apparatuses 3-1, 3-2), making it possible to make a recording scheduling of a program easily and swiftly without imposing burden on the user.

Meanwhile, because preference information can be exchanged between friends (user apparatuses in plurality), it is possible to view a program liked between the friends and to feel the preferences of the mutual users.

Furthermore, it is possible to levy from the user a use charge in return for the provision the server 2-1 (service provider) has provided the field for exchanging preference information, making commercialization feasible.

Meanwhile, the server 2-1 (service provider), because capable of gathering the customer information and preference information of the user on the user apparatus 3, can utilize it and make a product proposal, etc. effectively to the user.

Although the above was adapted to receive broadcast program information from the broadcast station through a broadcast radio wave, it can be received from the server 2-2 through the network 1. Meanwhile, although it was preference information that is to be registered to the server 2-1 and sent to the user apparatus 3, this is not limitative, e.g. preference information can be generated from the information of a program actually picture-recorded instead of scheduled by the user. In brief, any piece of information is to be applied provided that it is preference information capable of specifying a program as a subject of recording.

The foregoing one series of processes, although can be executed on hardware, can be carried out over software.

In the case of executing the series of processes on software, the program configuring that software is installed from the network or recording medium onto a computer incorporated in exclusive hardware or, for example, general-purpose personal computer capable of executing various functions by being installed with various programs.

The recording medium, as shown in FIG. 4, is configured not only by a removable media 231 constituted by a program-recorded magnetic disk (including floppy disk), optical disk (including CD-ROM (Compact Disk-Read Only Memory), DVD (Digital Versatile Disk)), magnetooptical disk (including MD (Mini-Disk) or semiconductor memory distributed for providing a program to the user separately from the apparatus main body, but also by a ROM 222 recording a program or a hard disk included in the storage section 228 provided in a state previously incorporated in the apparatus main body to the user.

Incidentally, in the present specification, the step describing a program recorded to the recording medium includes, of course a process to be chronologically made along a described order, also a process to be executed in parallel or discretely even if not necessarily to be processed chronologically.

Meanwhile, in the present specification, system represents the apparatus overall constituted by a plurality of apparatuses.
