The servers 2-1 and 2-2 provide program attribute information (program attribute information 431 in
The user apparatus 3 is arranged in a user's home, and the user apparatus 3-1 includes a video recording and reproducing apparatus 11, a display apparatus 12, and an antenna 13.
The video recording and reproducing apparatus 11 is, for example, a hard disk video recorder. The video recording and reproducing apparatus 11 receives a broadcast wave via the antenna 13 and causes an auxiliary storage 40 (see
Note that, although not shown in the figure, the user apparatus 3-2 is constituted in the same manner as the user apparatus 3-1.
The video recording and reproducing apparatus 11 is constituted, for example, as shown in
The encoder 32 encodes a video signal and a sound signal inputted from the tuner 31 in, for example, the MPEG (Moving Picture Experts Group) system, supplies the video signal and the sound signal to the auxiliary storage 40 via a bus 52, and causes the auxiliary storage 40 to store the video signal and the sound signal. The auxiliary storage 40 is constituted by a hard disk, a magnetic tape, a removable disk, a flash memory, or the like.
The video signal and the sound signal stored in the auxiliary storage 40 are outputted to a decoder 33 via the bus 52, decoded in the MPEG system and, then, supplied to the display apparatus 12. When the received video signal and sound signal are not stored in the auxiliary storage 40, the encoder 32 and the decoder 33 output a signal outputted from the tuner 31 to the display apparatus 12 directly.
A main storage 39 consisting of, for example, a RAM (Random Access Memory) and a ROM (Read Only Memory) 38 are connected to the bus 52. Data and parameters, which are required when a CPU (Central Processing Unit) 35 executes various kinds of processing, are stored in the main storage 39 according to circumstances. A program to be executed by the CPU 35 is stored in the ROM 38.
A network interface 37, which executes interface processing with the network 1, is further connected to the bus 52.
The CPU 35 is connected to a bus 51 together with the encoder 32, the decoder 33, and the EPG acquisition module 34. In addition, a main storage 36 constituted by a RAM or the like is connected to this bus 51.
A functional structure consisting mainly of software of the video recording and reproducing apparatus 11 is as shown in
The viewing control application 68 controls the live broadcast reproducing unit 61, the recording title reproducing unit 62, the recording title managing unit 65, or the broadcast program information managing unit 66 on the basis of an instruction from a user to reproduce a signal being received or inputted at that point or performs reproduction of a program stored in the auxiliary storage 40. In addition, when the viewing control application 68 controls the live broadcast reproducing unit 61 to cause the tuner 31 to receive a broadcast program of a channel designated by the user, the viewing control application 68 refers to broadcast program information stored in the broadcast program information managing unit 66 according to circumstance. Moreover, when the viewing control application 68 controls the recording title reproducing unit 62 to reproduce a program stored in the auxiliary storage 40, the viewing control application 68 refers to management information of a program stored in the recording title managing unit 65 according to circumstance.
The broadcast program information display application 69 refers to the broadcast program information (EPG information) stored in the broadcast program information managing unit 66 and causes the display apparatus 12 to display the broadcast program information. The recording reservation application 70 executes recording reservation processing on the basis of an instruction from the user. At this point, the recording reservation application 70 refers to the broadcast program information stored in the broadcast program information managing unit 66 as required. In addition, when the recording reservation application 70 performs recording reservation on the basis of operation from the user, the recording reservation application 70 controls the recording reservation managing unit 67 to execute recording reservation processing.
The recording title managing unit 65 manages information on a program (title) stored in the auxiliary storage 40. The broadcast program information managing unit 66 manages broadcast program information acquired by the EPG acquisition module 34. The recording reservation managing unit 67 controls the recording control unit 63 on the basis of a request from the recording reservation application 70 or an automatic recording reservation control unit 71 to execute recording reservation processing.
The automatic recording reservation control unit 71 executes recording reservation processing on the basis of program attribute information acquired from the server 2-1. A network communication unit 72 communicates with the servers 2-1 and 2-2 via the network 1 and acquires program attribute information and broadcast program information.
The server 2-1 is constituted, for example, as shown in
The CPU 221, the ROM 222, the RAM 223 are connected to one another via a bus 224. An input/output interface 225 is also connected to this bus 224.
An input unit 226 consisting of a keyboard, a mouse, or the like, a display consisting of a CRT (Cathode Ray Tube), an LCD (Liquid Crystal Display), or the like, an output unit 227 consisting of a speaker or the like, a storage unit 228 constituted by a hard disk or the like, and a communication unit 229 constituted by a modem or the like are connected to the input/output interface 225. Program attribute information to be provided to the user apparatus 3 is stored in the storage unit 228. The communication unit 229 performs communication processing via the network 1 including the Internet.
A drive 230 is also connected to the input/output interface 225 as required, and a removable medium 231 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory is mounted on the input/output interface 225 according to circumstances. A computer program read out from the removable disk is installed in the storage unit 228 as required.
Note that, although not shown in the figure, the sever 2-2 has basically the same structure as the server 2-1 shown in
Next, processing in which the user apparatus 3 acquiring program attribute information from the server 2-1 will be explained with reference to a flowchart in
In step S1, the automatic recording reservation control unit 71 controls the network communication unit 72 to access the server 2-1 via the network 1. In step S2, the automatic recording reservation control unit 71 controls the network communication unit 72 to request the server 2-1 to transfer program attribute information.
As described later with reference to
In association with the program attribute information acquisition processing of the video recording and reproducing apparatus 11 as described above, the server 2-1 executes processing indicated in the flowchart in
In step S21, the CPU 221 accepts an access from the video recording and reproducing apparatus 11 via the network 1. In step S22, the CPU 221 accepts the request for transfer of program attribute information that the video recording and reproducing apparatus 11 transmitted in processing in step S2. In step S23, the CPU 221 reads out the program attribute information stored in the storage unit 228 and controls the communication unit 229 to transmit the program attribute information to the video recording and reproducing apparatus 11 via the network 1.
As described above, the video recording and reproducing apparatus 11 of the user apparatus 3 acquires the program attribute information from the server 2-1 in advance and causes the auxiliary storage 40 to store the program attribute information.
Note that, when the auxiliary storage 40 is constituted by, for example, a removable disk or a flash memory, the user is provided with the medium, in which program attribute information is recorded, from an administrator of the server 2-1, whereby it is possible to cause the auxiliary storage 40 to hold the information.
Therefore, it is possible to rewrite (update) program attribute information to new information as required. As a result, for example, it is possible to provide each user with program attribute information matching a period when a program is broadcast such as a feature program on an election or a feature program on the Olympics. By providing such program attribute information, the administrator of the server 2-1 can apply charging processing to the user who is provided with the information and make a profit.
As described above, it is possible for the user, who has acquired the program attribute information, to reserve a desired program for recording easily. In performing the recording reservation, the user performs operation designating the program attribute information. Next, processing in this case will be explained with reference to a flowchart in
In step S41, the automatic recording reservation control unit 71 reads out program attribute names of the program attribute information, which is stored in the auxiliary storage 40 by processing in step S4, and causes the display apparatus 12 to display a list of the program attribute names. Consequently, for example, an image shown in
In an example in
In the example of display in
The keyword 441 is a keyword for, when the keyword is included in a title of a program included in EPG (broadcast program information) or detailed information introducing contents of the program, extracting the program as a program that is reserved to be recorded. In this example in
The escape keyword 442 is a keyword for, when the keyword is included in a title or detailed information of a program of EPG, excluding the program from a program that is reserved to be recorded. In the case of this example, “baseball” is set as an escape keyword. In the case of this example, since the program attribute name 432 is “soccer”, when the word “baseball” is included in a title or detailed information of a program, the program is excluded from recording reservation objects.
The genre 443 designates a genre of a program that is reserved to be recorded. In the case of this example, programs of genres with IDs “64” and “0” are set as reservation objects. The ID of “64” is a genre of, for example, soccer, and the genre of “0” is a genre of sports.
The day of week 444 designates a day of week on which a program set as a recording reservation object is broadcast. In the case of this example, a day of week with an ID “0” and a day of week with an ID “1” are designated. The day of week with the ID “0” is, for example, Sunday, and the day of week with the ID “1” is, for example, Monday.
The time frame 445 defines a time frame of a program set as a recording reservation object. In the case of this example, programs, which are broadcast between 17:00 and 23:00, are programs set as reservation objects.
The program length 446 defines a length of a program set as a reservation object. In the case of this example, programs with lengths of 15 minutes or more and 120 minutes or less are set as reservation objects.
The broadcasting station 447 designates a broadcasting station that broadcasts a program set as a reservation object. In the case of this example, a broadcasting station with an ID “2128” and a broadcasting station with an ID “2138” are designated.
The keyword 441, the escape keyword 442, the genre 443, the day of week 444, the time frame 445, the program length 446, and the broadcasting station 447 constituting the program attribute retrieval conditions 443 described above are not designated by each user but are set by the server 2-1 in advance in association with the program attribute name 432 of “soccer”. In other words, when a user designates the program attribute name “soccer” in
Referring back to
If it is judged in step S43 that an effective flag is not set, the processing proceeds to step S44 and the automatic recording reservation control unit 71 sets an effective flag in program attribute information of the program attribute name for which designation is accepted by processing in step S42. More specifically, in the state shown in
On the other hand, if it is judged in step S43 that an effective flag is already set, the processing proceeds to step S45 and the automatic recording reservation control unit 71 cancels the effective flag of program attribute information of the designated program attribute name. More specifically, for example, in the example of display in
If it is judged in step S42 that a program attribute name is not designated, or after the effective flag setting processing in step S44 or the effective flag cancellation processing in step S45 is executed, in step S46, the automatic recording reservation control unit 71 judges whether end of the program attribute information designation processing is instructed by the user. If the end is not instructed, the processing returns to step S42 and the automatic recording reservation control unit 71 executes the processing in step S42 and subsequent steps repeatedly. If it is judged in step S46 that the end of the program attribute information designation processing is instructed, the automatic recording reservation control unit 71 ends the processing.
As described above, simply by selecting predetermined program attribute names in an arbitrary number out of the program attribute names provided from the server 2-1, the user can set program attribute retrieval conditions associated with the program attribute names. Then, when this setting (selection) is performed, recording reservation is automatically performed as explained below.
Next, recording reservation processing, which is automatically executed by the automatic recording reservation control unit 71 after the user performs the designation processing for a program attribute name (program attribute information), will be explained with reference to a flowchart in
In step S61, the automatic recording reservation control unit 71 judges whether all pieces of broadcast program information (EPG information) are selected. As described above, the EPG information is acquired by the EPG acquisition module 34 and managed by the broadcast program information managing unit 66. More specifically, the EPG information is stored in the auxiliary storage 40.
In the example in
When it is judged in step S61 that all pieces of broadcast program information are not selected yet, the processing proceeds to step S62 and the automatic recording reservation control unit 71 selects one piece of broadcast program information out of the stored broadcast program information for, for example, two days. For example, broadcast program information of one program as shown in
Next, in step S63, the automatic recording reservation control unit 71 judges whether all effective pieces of program attribute information are selected. Here, effective program selection information means the program attribute information for which the effective flag is set by the processing in step S44 in
At this point, the processing proceeds to step S65 and the automatic recording reservation control unit 71 reads out retrieval conditions for the program attribute information selected by processing in step S64. For example, when program attribute information corresponding to the program attribute name “soccer” is selected by the processing in step S64, the program attribute retrieval conditions 433 shown in
Then, in the following steps S66 to S71, judgment processing on whether the broadcast program information (EPG information) selected by processing in step S62 is included in the retrieval conditions read out by processing in step S65 is performed.
More specifically, in step S66, it is judged whether a genre of the broadcast program information selected by the processing in step S62 (the genre in
In step S67, it is judged whether a broadcast date of the broadcast program information selected by the processing in step S62 (the broadcast date in
Moreover, in step S68, it is judged whether a start time of a program of the broadcast program information (the start time in
In step S69, it is judged whether a length of a program of the broadcast program information (a time calculated as a difference between the end time and the start time in
In step S70, it is judged whether a keyword of the retrieval conditions (the keyword 441 in
Moreover, in step S71, it is judged whether at least one escape keyword of the retrieval conditions (the escape keyword 442 in
When it is judged in all kinds of the judgment processing in steps S66 to S70 that the object items are included in the retrieval conditions and it is judged in step S71 that an escape keyword is not included in the title and the detailed information of the program, the processing proceeds to step S72 and the automatic recording reservation control unit 71 controls the recording reservation managing unit 67 to add the program currently set as a processing object to a recording reservation list.
The escape keyword in step S71 is a keyword for excluding a program from a retrieval object when the keyword is included in the program. Thus, a program satisfies the retrieval conditions when the program does not include the escape keyword. Therefore, only when all the items satisfy the retrieval conditions according to the processing from step S66 to step S71, the recording reservation processing in step S72 is performed.
In other words, when it is judged that the retrieval conditions are not satisfied in at least one kind of the judgment processing from step S66 to step S71, the recording reservation processing in step S72 is not executed, and the processing returns to step S63.
When it is judged in step S72 that the recording reservation processing is completed, the processing also returns to step S63.
In step S63, it is judged again whether all the effective pieces of program attribute information are selected. If all the effective pieces of program attribute information are not selected yet, in the example in
When the processing described above is repeated and if it is judged in step S63 that all the effective pieces of program attribute information are selected (if it is judged that all the three pieces of program attribute information “soccer”, “foreign film”, and “news” in
When the processing described above is repeated and if it is judged in step S61 that all the pieces of broadcast program information are selected (if it is judged that broadcast program information for programs for two days is selected), the processing is ended.
As described above, the automatic recording reservation control unit 71 causes the recording reservation managing unit 67 to create a recording reservation list shown in
In an example in
This recording reservation list is created automatically when a user simply performs operation for selecting program attribute names “foreign film”, “soccer”, and “news”. Therefore, the user is never forced to bear an excessive load in creating this recording reservation list.
Note that it is needless to mention that it is also possible that the user designates predetermined programs individually via the recording reservation application 70 to register the programs in the recording reservation list.
When the recording reservation list is created as described above, the recording reservation managing unit 67 executes recording processing for reserved programs. Next, this recording processing for reserved programs will be explained with reference to a flowchart in
In step S91, the recording reservation managing unit 67 judges whether all programs reserved in the recording reservation list are retrieved. If a reserved program not retrieved yet is present, the processing proceeds to step S92 and the recording reservation managing unit 67 extracts one program from the recording reservation list. In step S93, the recording reservation managing unit 67 reads out a broadcast date and time of the program extracted by processing in step S92. For example, when a program indicated by a number 1 in
In step S94, the recording reservation managing unit 67 reads a present date and time from a timer incorporated therein and judges whether the broadcast date and time read out by the processing in step S93 is within a standard time from the present date and time. The standard time is a relatively short time such as thirty seconds or one minute. This standard time is determined taking into account a time required until recording processing is actually started after control is instructed via the recording control unit 63.
If it is judged that the broadcast date and time is not within the standard time from the present date and time, the processing returns to step S91 and the processing in step S91 and subsequent steps is executed repeatedly.
For example, if the present date and time is 12:00:00 on Jul. 1, 2002, since the present date and time is four hours before the broadcast date and time, it is not judged that the broadcast date and time is within the standard time. The processing returns to step S91 and the judgment processing on whether all the reserved programs are retrieved is performed again. In the present case, since all the programs are not retrieved yet, the processing proceeds to step S92 and the next one program is extracted. For example, a program indicated by a number 2 in
In step S94, it is judged whether the broadcast date and time is within the standard time from the present date and time. If the broadcast date and time is not within the standard time, the processing returns to step S91 and the processing in step S91 and subsequent steps is executed repeatedly.
For example, when the program of the number 1 is selected and a present date and time is 15:59:30 on Jul. 1, 2002, a broadcast date and time 16:00:00 on Jul. 1, 2002 is within thirty seconds from the present date and time 15:59:30 on Jul. 1, 2002 (within a standard time) and, in step S94, it is judged that the broadcast date and time is within the standard time from the present date and time. In this case, the processing proceeds to step S95 and the recording reservation managing unit 67 controls the recording control unit 63 to receive a program set as an object presently. In the present case, the recording reservation managing unit 67 controls the recording control unit 63 to receive a broadcast wave of the broadcasting station TV Japan with the tuner 31.
In step S96, the recording reservation managing unit 67 controls the recording control unit 63 to store the program received by processing in
In other words, a video signal and a sound signal received by the tuner 31 at this point are supplied to the encoder 32 and, after being encoded in the MPEG system, supplied to the auxiliary storage 40 and stored therein.
In step S97, the recording reservation managing unit 67 judges whether the program ends by comparing a broadcast end time of the program for which the recording processing is executed presently and the present time. When the program does not end yet, the recording reservation managing unit 67 is on standby until the program ends. When the program ends, the processing proceeds to step S98 and the recording reservation managing unit 67 controls the recording control unit 63 to end the recording processing for the auxiliary storage 40. In addition, in step S99, the recording reservation managing unit 67 controls the recording control unit 63 to end the reception processing of the program by the turner 31.
In step S100, the recording reservation managing unit 67 deletes the program for which recording is completed presently from the recording reservation list.
If it is judged in step S91 that all the reserved programs are retrieved, the processing from step S92 to step S100 is skipped, and the processing is ended.
The processing described above is performed at every fixed time, and programs registered in the recording reservation list are sequentially recorded in the auxiliary storage 40 automatically.
Note that it is possible to sort and arrange the recording reservation list shown in
When programs are recorded in the auxiliary storage 40 as described above, the recording title managing unit 65 registers and manages information such as titles and broadcast date and times of the recorded programs.
When the user instructs reproduction of a recorded program via the viewing control application 68, the viewing control application 68 reads out program titles recorded in the auxiliary storage 40 with reference to the management information of the recording title managing unit 65 and causes the display apparatus 12 to display the program titles. When the user looks at this display and selects a program to be an object of reproduction, the viewing control application 68 instructs the recording title reproducing unit 62 to reproduce the program. The recording title reproducing unit 62 reproduces the instructed program from the auxiliary storage 40. Video data and sound data reproduced from the auxiliary storage 40 are inputted to the decoder 33 and, after being decoded in the MPEG system, outputted to the display apparatus 12 and displayed thereon.
In the above description, broadcast program information is received from a broadcasting station via a broadcast wave. However, it is also possible to receive the broadcast program information from the server 2-2 via the network 1.
The series of processing described above can be executed by hardware or can be executed by software.
When the series of processing is executed by software, a program constituting the software is installed in a computer, which is incorporated in dedicated hardware, a computer such as a personal computer, which is capable of executing various functions by installing various programs, or the like from a network or a recording medium.
As shown in
