Problems that Invention is to Solve
However, the above-mentioned conventional arts do not handle, using the same interface, contents (such as program contents broadcast and accumulated in the past), programs which are being broadcast currently, and information of programs which are to be broadcast from now on. Therefore, it is not possible for a user to seamlessly handle past contents, current contents and future contents which are processed in a digital television equipped with a large capacity hard disk or the like which is currently on the market and expected to be more popular from now on, a video system in which a television and a hard disk drive are connected, or the like.
In the conventional arts, it is not also possible for a user to distinguish past contents, current contents and future contents from each other clearly at a glance.
The present invention has been conceived in view of the above circumstances, and it is an object of the present invention to provide an information output apparatus which is capable of not only seamlessly handling past contents, current contents and future contents but also displaying these past, current and future contents for easy viewing so that they are clearly distinguished from each other.
Means to Solve the Problems
In order to attain the above-mentioned object, the information output apparatus according to the present invention is characterized in that it includes: a past content information storage unit which stores one or more items of past content information, each including at least one of a past content and information about the past content, the past content being a content accumulated in the past; a current content information storage unit which stores one or more items of current content information, each including at least one of an entirety or a part of a current content and program information, the current content being a currently broadcast program, and the program information being information about the current content; a future content information storage unit which stores one or more items of future content information, each being information about a future content that is a program to be broadcast from now on; and an output unit operable to arrange content information that is the past content information, the current content information and the future content information, and to output the content information in visually different display styles, based on time-related information included in the content information.
This structure enables a user to seamlessly handle past contents, current contents and future contents which are processed in a digital television equipped with a large capacity hard disk or the like which is currently on the market and expected to be more popular from now on, a video system in which a television and a hard disk drive are connected, or the like. It also becomes possible to display past contents, current contents and future contents for user's easy viewing so as to be clearly distinguished from each other.
Here, it is preferable that the above output unit outputs the content information in a display style in which color information of display gradually changes, per predetermined unit of the content information, according to the time-related information.
The output unit may also output the content information in a display style in which size of display gradually changes, per predetermined unit of the content information, according to the time-related information.
This makes it possible to display past contents, current contents and future contents for user's easy viewing so that they are clearly distinguished from each other.
Note that it is possible to embody the present invention not only as such information output apparatus, but also as an information output method that includes, as its steps, the characteristic units included in such information output apparatus, and as a program causing a computer to execute such steps. It should be also noted that such program can be distributed on a recording medium such as a CD-ROM and over a transmission medium such as the Internet.
Effects of the Invention
According to the information output apparatus of the present invention, it becomes possible not only to seamlessly handle contents which were accumulated in the past, contents which are being broadcast currently, and contents which are to be broadcast in the future, but also to display these past contents, current contents and future contents for user's easy viewing so that they are clearly distinguished from each other.
The embodiments of an information output apparatus and the like will be described below with reference to the drawings. It should be noted that since the constituent elements assigned with the same reference numbers perform the same operations in the embodiments, the description thereof may not be repeated.
The sending information storage unit 1101 stores program information that is programs to be sent and the information about the programs. Here, sending usually means broadcast, but it may be communication using a network. Such communication may be wireless communication or wire communication. Furthermore, such communication may be communication with a specified partner or communication with an unspecified partner. Program information is, for example, information indicating a program title or a broadcast time slot, information indicating program performers' names, information indicating a program categories, or the like. A nonvolatile recording medium is suitable for the sending information storage unit 1101, but it may be embodied by a volatile recording medium.
The sending unit 1102 sends programs and program information stored in the sending information storage unit 1101. The sending unit 1102 can be embodied by a broadcast means, a wireless or wire communication means, or the like. Here, broadcast is a concept including digital terrestrial broadcast, analogue terrestrial broadcast, satellite broadcast, CATV broadcast, Internet broadcast and the like.
The receiving unit 1201 receives programs and program information. The receiving unit 1201 can be embodied by, for example, a tuner and its driver software. The receiving unit 1201 can also be embodied by, for example, a wireless or wire communication means or the like.
The accepting unit 1202 accepts a user's instruction. There are various instructions, for example, an instruction by a mouse click, an instruction by pressing the Enter button of a remote control, and the like. Or, the instruction may be a reproduction instruction to instruct reproduction of an accumulated content (hereinafter referred to as a past content), a viewing instruction to instruct viewing of a program which is being broadcast currently (hereinafter referred to as a current content), a recording instruction to instruct recording of a program which is to be broadcast from now on (hereinafter referred to as a future content), or the like. Or, the instruction may be, for example, a content list output instruction. The content list output instruction is an instruction to instruct output of a list of past content information or current content and future content information. The means for inputting such instruction may be anything such as a ten-key numeric keypad, a keyboard, a mouse, a remote control or a menu screen. The instruction may be an instruction about past content information, current content information or future content information. The accepting unit 1202 can be embodied by a device driver of an input means such as a ten-key numeric keypad, a keyboard, a remote control, or a control software for a menu screen.
The past content information storage unit 1203 stores one or more items of past content information being the information about past contents accumulated in the past. A content means, for example, a received program, a movie obtained through communication, a movie accumulated in an optical disk, or the like. The past content information may be a past-accumulated content itself, a still image (frame) that is an element of a past-accumulated content (including a moving image), information of the title, performers' names and the like of a past-accumulated content, or information including a past-accumulated content itself as well as its title, performers' names and the like. It should be noted that in the case where a content is a program which has been broadcast via digital broadcast or the like, past content information may include so-called SI information. This SI information includes the information about a program title, performers' names and the like.
The current content information storage unit 1204 stores one or more current content information, each including program information that is the information about a current content which is being broadcast currently and/or the entirety or a part of the current content. Program information is, for example, SI information. The entirety of a current content is the information of a program itself. Information of a program itself usually includes information of moving images and sound. Information of a program itself may include subtitle information. Current content information may be a still image (frame) that is an element of a program which is being broadcast currently.
The future content information storage unit 1205 stores future content information that is the information of future contents of the programs which are to be broadcast from now on. Future content information is, for example, SI information. Future content information does not usually contain the information of a program itself.
A nonvolatile recording medium is suitable for the past content information storage unit 1203, the current content information storage unit 1204 or the future content information storage unit 1205, but each of them may be embodied by a volatile recording medium. It should be noted that the past content information storage unit 1203, the current content information storage unit 1204 and the future content information storage unit 1205 may be embodied as a single recording medium, or may be embodied as two or more recording media. For example, it is possible that the past content information storage unit 1203 and the future content information storage unit 1205 are embodied by nonvolatile recording media, while the current content information storage unit 1204 is embodied by a volatile recording medium.
The past content information accumulation unit 1206 accumulates past content information in the past content information storage unit 1203. The past content information accumulation unit 1206 may accumulate past content information according to a user's instruction accepted by the accepting unit 1202, or automatically accumulate past content information.
The current content information accumulation unit 1207 accumulates current content information in the current content information storage unit 1204. The current content information accumulation unit 1207 usually accumulates current content information automatically, but it may accumulate current content information according to a user's instruction accepted by the accepting unit 1202.
The future content information accumulation unit 1208 accumulates future content information in the future content information storage unit 1205. The future content information accumulation unit 1208 also usually accumulates future content information automatically, but it may accumulate future content information according to a user's instruction accepted by the accepting unit 1202.
Each of the past content information accumulation unit 1206, the current content information accumulation unit 1207 and the future content information accumulation unit 1208 can usually be embodied by an MPU, a memory or the like. The processing procedure of each of the past content information accumulation unit 1206, the current content information accumulation unit 1207 and the future content information accumulation unit 1208 is usually embodied by software recorded on a recording medium such as a ROM. However, it may be embodied by hardware (a dedicated circuit). It should be noted that the current content information accumulation unit 1207 and the future content information accumulation unit 1208 may work at the same time. In other words, for example, in the case where both current content information and future content information are so-called electronic program table information (SI information), they are usually accumulated without being distinguished from each other.
The output unit 1209 arranges, in two or more approximate circles, all or a part of past content information and current content information, or all or a part of past content information, current content information and future content information, and outputs them so that the two or more approximate circles are arranged in an approximately concentric manner, based on predetermined concepts of past contents and current contents, or those of past contents, current contents and future contents. A predetermined concept means a time concept or a concept indicated by another attribute value. Another attribute value is, for example, a data size, a category (a program type such as news, dramas and sports), performers' names, or the like. It should be noted that a time concept is a concept indicated by an attribute value of time (including time slot) such as a time at which a content has been accumulated, a time at which a content has been broadcast, or a time at which a content is to be broadcast. A time concept that is one of the predetermined concepts may be considered as time information that is the time-related information. In addition, it is preferable that the output unit 1209 arranges, in two or more approximate circles, all or a part of past content information and current content information, or all or a part of past content information, current content information and future content information, and outputs them so that the two or more approximate circles are arranged in an approximately concentric manner, based on time-related information of past contents and current contents, or that of past contents, current contents and future contents. It is also preferable that the output unit 1209 outputs, in different approximate circles, all or a part of past content information and current content information, or all or a part of past content information, current content information and future content information. Furthermore, it is preferable that the output unit 1209 outputs current content information in the most eye-catching display manner. Outputting current content information in the most-eye-catching manner means, for example, displaying current content information in a larger size than past content information, or than past content information and future content information. Outputting current content information in the most eye-catching manner means, for example, displaying current content information in a more unblurred and clearer display manner than past content information, or than past content information and future content information. A blurred display means a display of an image on which blur processing is performed, a display of lower brightness, a display of which color has been changed based on the time concept such as past, current or future time, a transmittance-changed display, or the like. The above-mentioned output is a concept which mainly means a display on a display screen, but includes sound output, print output to a printer, sending to an external device and the like. It does not matter whether or not the output unit 1209 includes an output device such as a display and a speaker. The output unit 1209 can be embodied by software for performing output processing, or a combination of a software for performing output processing, a driver software of an output device, the output device, and the like.
The operating unit 1210 reproduces a past content corresponding to past content information in the case where the accepting unit 1202 accepts a reproduction instruction of the past content information outputted from the output unit 1209. The operating unit 1210 switches viewing to a current content corresponding to current content information in the case where the accepting unit 1202 accepts a viewing instruction of the current content information outputted from the output unit 1209. The operating unit 1210 presets timer recording of a future content corresponding to future content information in the case where the accepting unit 1202 accepts a recording instruction of the future content information outputted from the output unit 1209. It should be noted that the operating unit 1210 may output a received program. In such case, the accepting unit 1202 accepts, for example, a selection of a menu item (such as a menu item of a reproduction instruction, a menu item of a viewing instruction and a menu item of a recording instruction) on a menu screen.
The operating unit 1210 reproduces a past content corresponding to the past content information outputted from the output unit 1209, in the case where the accepting unit 1202 has accepted an instruction of the past content information. The operating unit 1210 switches viewing to a current content corresponding to the current content information outputted from the output unit 1209, in the case where the accepting unit 1202 has accepted an instruction of the current content information. The operating unit 1210 presets timer recording of a future content corresponding to the future content information outputted from the output unit 1209, in the case where the accepting unit 1202 accepts an instruction of the future content information. In such case, the accepting unit 1202 has accepted the same action (for example, pressing the ENTER button) with respect to past content information, current content information and future content information. It is assumed that the operating unit 1210 also performs an operation such as recording in addition to the above.
The reproduction unit 12101 reproduces a past content corresponding to past content information. The view switching unit 12102 switches viewing to a current content corresponding to current content information. The timer recording preset unit presets a timer recording of a future content corresponding to future content information. The recording unit 12104 performs a recording corresponding to a preset timer recording. Since the reproduction unit 12101, the viewing switching unit 12102, the timer recording preset unit 12103 and the recording unit 12104 can be embodied using the existing techniques, a detailed description thereof is not made here.
The operation of the information processing system will be described below. First, the operation of the sending apparatus 11 will be described. The sending unit 1102 of the sending apparatus 11 sends programs and program information stored in the sending information storage unit 1101. It does not matter if the sending unit 1102 uses any trigger for sending such programs and program information. The sending unit 1102 usually sends a previously stored program based on the information of the broadcast schedule of the program. Program information may be sent in a manner in which it is superimposed on a program, or may be sent over a separate channel from the program.
Next, the operation of the information output apparatus 12 will be described with reference to the flowcharts of

(Step S309) The output unit 1209 outputs a content list. To be more specific, the output unit 1209 arranges, in two or more approximate circles, all or a part of past content information and current content information, or all or a part of past content information, current content information and future content information, and outputs them so that the two or more approximate circles are arranged in an approximately concentric manner, based on predetermined concepts of past contents and current contents, or those of past contents, current contents and future contents. The specific example of the content list output from the output unit 1209 will be described later. It should be noted that the detailed example of the content list output operation by the output unit 1209 will be described with reference to the flowchart of
(Step S310) The accepting unit 1202 judges whether or not it has accepted an instruction for a past content. If it has accepted an instruction for a past content, the process goes to Step S313, while it has not accepted an instruction of a past content, the process jumps to Step S312.

It should be noted that in the flowchart of
In the flowchart of
Next, a detailed example of a content list output operation will be described with reference to the flowchart of
(Step S401) The output unit 1209 obtains current content information stored in the current content information storage unit 1204.
(Step S402) The output unit 1209 places a predetermined number of current content information in an approximate circle. The output unit 1209 usually places two or more items of current content information equally spaced apart. The predetermined number may be previously determined, or may be the total number of current content information.
(Step S403) 1 is substituted into counters i and j. 1 is substituted into a blurring coefficient. A blurring coefficient is information indicating a degree of blurring of past content information or future content information to be displayed. It is assumed here that a content to be displayed is displayed in a more blurred manner as the value of the blurring coefficient increases.
(Step S404) The output unit 1209 judges whether or not the “i”th circle of the past content information is to be displayed. Since the number (the value thereof is “n”) of concentric circles is usually determined for a display of past content information, and the output unit 1209 makes the judgment based on the comparison between this value “n” and “i”. If it judges that the “i”th circle is to be displayed, the process goes to Step S405, while if it judges that the “i”th circle is not to be displayed, the process jumps to Step S412.
(Step S405) The output unit 1209 judges whether or not the “j”th past content information can be placed on the “i”th circle. It should be noted that the number of content information to be placed on a single circle is usually predetermined, and if the number of content information exceeds this number (a predetermined number), the “j”th past content information is not placed on the “i”th circle. If the “j”th past content information can be placed, the process goes to Step S406, while if the “j”th past content information cannot be placed, the process jumps to Step S410.
(Step S406) The output unit 1209 judges whether or not there is the ((i−1)×predetermined number+j)th latest past content information. If there is the ((i−1)×predetermined number+j)th latest past content information, the process goes to Step S407, while if there is no such information, the process jumps to Step S412.

(Step S408) The output unit 1209 places the ((i−1)×predetermined number+j)th latest past content information at a predetermined position on the “i”th circle. It should be noted that placing means the processing for writing information at a predetermined coordinate position in a VRAM.
(Step S409) The output unit 1209 increments “j” by one. The process returns to Step S405.
(Step S410) The output unit 1209 increments “i” by one.
(Step S411) The output unit 1209 increments the blurring coefficient by one. The process returns to Step S404.
(Step S412) The output unit 1209 substitutes 1 into the counter i. The output unit 1209 substitutes 1 into the blurring coefficient.
(Step S413) The output unit 1209 judges whether or not to display the “i”th circle of future content information. If it judges that the “i”th circle is to be displayed, the process goes to Step S414, while if it judges that the “i”th circle is not to be displayed, the process goes to Step S418. Note that it is assumed that the number of circles to be displayed is previously determined for future content information.
(Step S414) The output unit 1209 obtains all the future content information to be placed on the “i”th circle from the future content information storage unit 1205. It should be noted that the number of future content information which can be placed on a single circle may be previously determined, or all the future content information to be broadcast within a predetermined period of time (for example, three hours from now on) may be placed on a single circle.
(Step S415) The output unit 1209 places all the future content information obtained in Step S414 on the “i”th circle.
(Step S416) The output unit 1209 increments “i” by one.
(Step S417) The output unit 1209 increments the blurring coefficient by one. The process returns to Step S413.
(Step S418) The output unit 1209 renders the placed content information. The processing of the output unit 1209 in this step is, for example, processing for outputting the screen images written in a VRAM on a screen.
It should be noted that in the flowchart of

Past content information stored in the past content information storage unit 1203 includes a recorded program and program information including information of the broadcast time slot of the program, program title, performers' names and the like. Past content information stored in the past content information storage unit 1203 is shown in
A current content is a program which is being broadcast currently. It is assumed that the current time is Aug. 5, 2004, 19:15. Current content information stored in the current content information storage unit 1204 is assumed to be information (SI information) of a previously received and accumulated electronic program table. Program information includes information of a broadcast channel, a broadcast date, a broadcast time slot, a title, a category and performers.
Furthermore, a future content is a program to be broadcast from now on. Future content information stored in the future content information storage unit 1205 is assumed to be previously received and accumulated program information (SI information). In other words, future content information and current content information are the same information here. The information output apparatus 12 contains a clock, and obtains current content information or future content information from the information of the stored electronic program table, based on the current time information of the clock.
Note that

Next, the output unit 1209 substitutes 1 into the blurring coefficient. Then, the output unit 1209 performs the following processing in order to display the first approximate circle of the past content information. To be more specific, it searches for the past content information which has been accumulated in the recent past. In more detail, the output unit 1209 first obtains, from the past content information management table of
Next, the output unit 1209 changes the blurring coefficient to 2. Then, the output unit 1209 performs the following processing in order to display the second approximate circle of the past content information. To be more specific, the output unit 1209 obtains the ninth to seventeenth items of past content information (the ninth to seventeenth items of information from the latest one in the broadcast time slots in the table of
Next, the output unit 1209 changes the blurring coefficient to “3”. The output unit 1209 performs the following processing in order to display the third approximate circle of past content information. To be more specific, the output unit 1209 obtains the eighteenth to twenty-fifth items of past content information.
