Description

  The present invention relates to, for example, a broadcast program reservation method and a broadcast program reservation device for reserving viewing or recording of a broadcast program in digital broadcasting, and a digital broadcast receiving device and a video recording / reproducing device to which the broadcast program reservation method or device is applied. And an image display device.

  In general, in digital broadcasting, a video signal, an audio signal, and data are multiplexed and transmitted. Many programs and many types of services included in the multiplexed signal include program arrangement information (SI: Service Information) used to select a program desired by the viewer. The SI is composed of four tables: SDT (Service Description Table), EIT (Event Information Table), BAT (Bouquet Association Table), and TDT (Time Date Table). The SDT includes information related to the name of the organization channel, the name of the operator, and the service format (television, voice, data). EIT includes a program title and simple contents of the program, detailed contents of the program, and information of each component constituting the program (video quality, aspect ratio, whether the sound is stereo sound and surround sound, etc.) Information about the genre of the program is included. The BAT includes information regarding the organization channel and the service format that are configured as a bouquet (a set of a plurality of services transmitted by the same operator). The TDT includes information related to the current time and date. Thus, since various information about a program is provided by SI, the program information can be displayed as an electronic program guide (EPG) on a screen in a desired layout.

  When a broadcast program is reserved, a general method is to display a program list in which program titles and the like are listed for a program scheduled to be broadcast for a certain period including the current time, and select and specify a program title to be reserved. However, the program displayed in the program list is always a program scheduled to be broadcast after the present time, and a program broadcast in the past cannot be displayed. For this reason, when a program that has been broadcast in the past (missed, not recorded, or desired to watch again) is checked to see if it will be rebroadcast, When is the broadcast date and time, whether there is a re-broadcast by another broadcast station, where is the other broadcast station that performs the re-broadcast, and when is the re-broadcast date and time by the other broadcast station? It took a lot of time and effort to know if there was a continuous program).

  As an improvement measure, there is a proposal of a technique for setting playback / recording reservation for a next broadcast program or a rebroadcast program by pressing a next broadcast program reservation key on the remote controller while watching the program (for example, Patent Documents). 1).

Japanese Patent Laid-Open No. 10-200805

  However, the above-described conventional reservation method performs reservation setting while viewing a program, and is not a reservation method for a program broadcast in the past. Therefore, when reserving a rebroadcast program or a next broadcast program that has been broadcast in the past, is there any rebroadcast, what is the program title, when is the rebroadcast date and time, rebroadcast by another broadcast station? It takes a lot of time and effort to know if there are other broadcast stations that will re-broadcast, when the re-broadcast date and time by other broadcast stations, if there is a next broadcast program (in the case of a continuous program), etc. There was a problem that time had to be spent.

  Therefore, the present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide a broadcast program reservation method and a broadcast that can easily reserve a program broadcast in the past. A program reservation apparatus and a digital broadcast receiving apparatus, a video recording / reproducing apparatus, and a video display apparatus to which the broadcast program reservation method or apparatus is applied.

  The broadcast program reservation method of the present invention is a method for reserving viewing or recording of a broadcast program, the step of acquiring broadcast program information, the step of setting a past program information storage period, and the acquired broadcast program Of the information, a step of storing information relating to a broadcast program that has been broadcast within the past program information storage period as past program information, a step of displaying the stored past program information, and the displayed past A step of designating a temporarily reserved program based on program information; and a step of registering the temporarily reserved program as a fully reserved program when the program information of the temporarily reserved program satisfies a predetermined requirement. .

  The broadcast program reservation apparatus of the present invention is an apparatus for reserving viewing or recording of a broadcast program, and includes a broadcast program information acquisition means for acquiring broadcast program information and a past program for setting a past program information storage period. Information storage period setting means, the broadcast scheduled program information is stored, and information on the acquired broadcast scheduled program information related to a program that has been broadcast within the past program information storage period is past program information. Storage means for storing; video processing means for displaying the stored past program information; temporary reserved program specifying means for specifying a temporary reserved program based on the displayed past program information; And control means for registering the provisional reserved program as a main reserved program when the program information satisfies a predetermined requirement.

  According to the present invention, program information of already broadcasted programs is stored, the stored past program information is displayed, a temporarily reserved program is designated based on the display information, and the temporarily reserved program When the requirement is satisfied, the execution of the reservation operation is confirmed for the provisional reservation and changed to the actual reservation, and the reservation operation is executed. Therefore, for example, it is possible to easily reserve a program broadcast in the past such as a missed program, a program that has not been recorded, or a program that is desired to be viewed again.

  FIG. 1 shows a configuration of a digital broadcast receiving apparatus (that is, a digital broadcast receiving apparatus including a broadcast program reservation apparatus according to an embodiment of the present invention) that can execute the broadcast program reservation method according to the embodiment of the present invention. FIG.

  The digital broadcast receiving apparatus shown in FIG. 1 is merely an example of an apparatus that can execute the broadcast program reservation method according to the embodiment of the present invention, and executes the broadcast program reservation method according to the embodiment of the present invention. Examples of devices that can be used include a video recording / playback device, a video display device (television), a personal computer (PC), and the like.

  The digital broadcast receiving apparatus shown in FIG. 1 includes a receiving antenna 1 that receives broadcast waves, a demodulation processing unit 2, a descrambling / demultiplexing unit 3, a video / audio decoding processing unit 4, and graphic generation / superimposition. Unit 5, video processing unit 6, display device 7, audio processing unit 8, speaker 9, first storage unit 10 for storing program information and the like, and second storage for storing video and audio data Unit 11, main control unit 12, clock processing unit 13, self-issued mail processing unit 14, remote control processing unit 15, and remote control 16.

  The broadcast wave transmitted from the broadcast station is received by the receiving antenna 1 and then sent to the demodulation processing unit 2. The demodulation processing unit 2 performs demodulation processing on the received broadcast wave and sends the demodulated signal to the descrambling / demultiplexer processing unit 3. The descrambling / demultiplexer processing unit 3 performs descrambling of the demodulated signal and separation of video data, audio data, other data, and the like. The separated video and audio data is sent to the video / audio decoding processing unit 4. The video / audio decoding processing unit 4 performs MPEG2 decoding processing on each of the video and audio data. Next, the stored program information data after the current time is sent to the graphic generation / superimposition unit 5 via the main control unit 12 to generate and decode an electronic program guide in a program list. It is superimposed on the data.

  The video data on which the electronic program guide is superimposed is converted into a video format selected and set in advance by the video processing unit 6, then sent to the display device 7, and the video is displayed on the display device 7. The decoded audio data is sent to the audio processing unit 8 and converted into an analog audio signal, and then output from the speaker 9 as audio.

  When a user of a device makes a program reservation, he / she browses an electronic program table listing programs after the current time (that is, a broadcast scheduled program) superimposed on the video data, and makes a reservation by operating the remote controller 16 or the like. A reserved program is determined by selecting and specifying a program to be performed. When the reservation start time coincides with the current time managed by the timing processor 13, the viewing reservation or the recording reservation is executed, and the viewing or recording operation is started. Further, when the reservation end time coincides with the current time managed by the timing processing unit 13, the viewing or recording operation is ended. In addition, when a recording reservation is performed, video and audio data are sequentially accumulated in the second storage unit 11. The above is the normal reservation operation.

  Next, a broadcast program reservation method in the present invention will be described. As already described, the program information after the current time sent together with the video and audio data is sequentially stored in the first storage unit 10. At this time, the program information related to the program ended before the current time is held in the first storage unit 10 for a certain period according to the past program information holding period set in advance by the user of the apparatus. If the past program information retention period is specified as, for example, one month, the past program information from the current time to one month before is retained, and old past program information exceeding one month from the current time is automatically deleted. To do.

  If there is a program that the user of the device has previously missed (or a program that was previously viewed but wants to be watched again, or a program that was not previously recorded), by pressing the missed program reservation key on the remote control 16, A signal from the remote control 16 is received by the remote control processing unit 15, and the missed program reservation key is determined and transmitted to the main control unit 12. As a result, the main control unit 12 calls the data to the area of the first storage unit 10 in which the past program information is stored in the first storage unit 10 and stores the past in the graphic generation / superimposition unit 5. Program information is sent, a past program list is generated and superimposed on the video data, and displayed on the display device 7 via the video processing unit 6 so that the user of the device can view it. The user of the apparatus can search for a missed program from the past program list.

  FIG. 2 is a display example of a program list for the past seven days generated based on program information before the current time. From the past program list before the current time, a search is made as to whether there is a missed program (or a program that has not been recorded or that you want to watch again). FIG. 3 shows a display example in the case where there is a program missed from the past program list before the current time (or the program has not been recorded or the user wishes to view it again). In FIG. 3, when the missed program is a movie 21, a provisional reservation (a provisional viewing reservation or a recording provisional reservation) can be performed by selecting and specifying a location where the program is displayed. Here, the “provisional reservation” is a reservation set by the user of the apparatus based on the past program information, and execution of the reservation operation is unconfirmed (that is, viewing or recording may not be executed). The word “temporary” is attached in the meaning. The temporary reservation becomes a main reservation (viewing book reservation or recorded book reservation) when the program information of the temporarily reserved program satisfies a predetermined requirement. Here, “book reservation” is given the letter “book” in the sense that execution of the reservation operation is confirmed (ie, viewing or recording is executed).

  The case where the program information of the temporarily reserved program satisfies the requirement is, for example, the case where the program information of the temporarily reserved program includes date / time information of rebroadcast or next broadcast and the date / time information has not passed the current time.

  If the program information of the provisional reserved program satisfies the requirements, for example, the provisional reservation is included in the broadcast scheduled program information already acquired when the provisional reserved program is specified or the broadcast scheduled program information acquired after the provisional reserved program is designated. This is a case where there is a broadcast program having a predetermined common point with the program information of the program. Here, a broadcast program having a predetermined common point is a character string that matches a character string that constitutes a program title of a temporarily reserved program (a match of a predetermined number of characters, a match of a predetermined number of consecutive characters, or a complete match, etc.) , A rebroadcast program having a program title including, a next broadcast program, or a related program.

  FIG. 4 is a flowchart showing the provisional reservation setting process. The processing procedure up to the completion of provisional reservation setting will be described based on this flowchart.

  First, by pressing a missed program reservation key provided in the remote controller 12 (step S1), a past program list generated based on past program information is displayed on the display device 7 (step S2).

  Next, the user of the apparatus browses the past program list and confirms whether there is a program that has been missed before (or a program that has not been recorded, etc.) (step S3). As a result, if the previously missed program is not on the past program list (when the determination in step S4 is “None”), the provisional reservation setting operation is terminated as it is. If it is on the past program list (when the determination in step S4 is “Yes”), the program that has been missed is selected and specified from the program list.

  Next, it is selected whether the reservation is set as a viewing reservation or a recording reservation for the rebroadcast or the next broadcast of the missed program (step S6). As a result of the selection, setting of provisional viewing reservation (step S8) or provisional recording reservation (step S7) is selected, and provisional reservation setting is completed (step S9).

  FIG. 5 is a flowchart showing the reservation setting process. The processing procedure up to the completion of the reservation setting will be described based on this flowchart. This process is executed after the provisional reservation setting is completed.

  First, it is checked whether the program information of the temporarily reserved program includes date / time information related to rebroadcast or next broadcast (step S12). If there is date / time information related to rebroadcast or next broadcast in the program information of the provisional reserved program, it is further checked whether the date / time information has passed the current time (step S13). If not, the provisional reservation setting is updated to the actual reservation setting (step S14), and an internal mail for notifying the reservation update completion is sent to notify the user of the apparatus that the reservation setting status has been updated. Issued (step S15). If the date and time information related to the rebroadcast or next broadcast has passed the current time, the program information of the program that has passed the current time is automatically retrieved and re-acquired, and the broadcast program that has passed the current time is newly acquired. A reserved program is set (step S16), and the process of step S12 is executed for a new temporary reserved program.

  Next, if there is no date / time information related to the rebroadcast or the next broadcast as a result of checking whether there is date / time information related to the rebroadcast or the next broadcast in the program information of the temporarily reserved program, all after the current time It is confirmed whether there is a program with the same program genre and the same program title in the program information (step S17), and if there is a program with the same program title, it is updated to the present reservation setting (step S14). If there is no program of the same program title, it is checked whether or not the provisional reservation setting has passed the provisional reservation retention period preset by the user of the device (step S18), and the provisional reservation retention period has expired. If so, the provisional reservation information whose retention period has expired is deleted (step S19). If the provisional reservation retention period has not passed, the program waits until new program information is updated (step S21), and after the program information is newly acquired and updated, the process is re-executed from step S17. For example, if the provisional reservation retention period is set to one month, the provisional reservation information is retained in the apparatus for one month from the provisional reservation time point.

  As described above, according to the broadcast program reservation method or the broadcast program reservation device of the present embodiment, a related program (for example, a rebroadcast program, a next broadcast program, or a title with the same title) that has been overlooked. By making a provisional viewing reservation or recording provisional reservation for a program), an automatic update setting to the viewing book reservation or the recording book reservation is performed, so that it is possible to easily make reservations for related programs of programs broadcast in the past. .
