Description

  Embodiments described herein relate generally to a digital broadcast receiver capable of recording a program received by digital broadcasting and a recorded program display method for a recorded program.

  In recent years, terrestrial digital broadcasting and BS / CS digital broadcasting have been fully operated, and an environment in which many programs can be viewed with high image quality and high sound quality has been established. Digital broadcasting has an electronic program guide (EPG) system, which can display a program guide for up to one week ahead, display program contents such as broadcast times and performers, and information you want to know. Search, program viewing reservation and recording reservation can be made.

  As the number of channels increases, the broadcast time of the program that the viewer wants to watch increases, and the broadcast time may overlap, so the opportunity to record the program and view the program at the convenience of the viewer Has increased. Digital broadcast receivers that can simultaneously record programs of a plurality of channels using a recording device having a plurality of tuners and a relatively large storage capacity have appeared.

JP 2001-186472 A

  A digital broadcast receiver with multiple tuners and a relatively large recording capacity, or an externally connected digital broadcast receiver, can simultaneously record programs for multiple channels. It is possible to select and reproduce a desired program from among a large number of programs.

  The viewer views a desired recorded program by making a selection using the cursor button of the remote controller while pressing the enter button while viewing the program list of the recorded program displayed like the program column of a newspaper. To view another recorded program while watching a recorded program, display the program list of the recorded program again, select the same using the cursor button on the remote control, and press the enter button. Press to watch another program.

  In order to display a program guide of recorded programs, it takes a long time to display a large amount of program information on a screen because a large amount of recorded program information is acquired and displayed together. Since the processing load is large, it is difficult to display the program table of the recorded program at the same time during the reproduction of the recorded program. Even for a mini-program guide in which the number of recorded programs displayed on the screen and the number of channels are reduced, the load for collecting and displaying program information is still large.

  As described above, when viewing another recorded program during playback of a recorded program, display the program guide of the recorded program or the mini program guide of the recorded program and use the cursor buttons on the remote control. You have to select and press the enter button, and the operation is cumbersome. Furthermore, since it takes time to display the program guide of the recorded program or the mini program guide of the recorded program, it is difficult to reproduce another recorded program in a short time.

  Normally, when viewing a broadcast TV program, it is possible to directly select a channel by operating a channel button on the remote controller or to perform a zapping viewing using a channel advance button. Realizing zapping of recorded programs during playback of recorded programs does not mean that all channels and programs are recorded, so it is possible to realize zapping using the channel button or channel feed button on the remote control difficult. Further, as described above, since it takes a plurality of operations and display time to display the program guide of the recorded program, it is difficult to realize zapping of the recorded program.

  An object of the present invention is made in view of the above-described circumstances, and is a digital broadcast reception that allows a viewer to easily play back other recorded programs during playback of a recorded program. And a recorded program display method.

  In order to achieve the above object, according to the embodiment, the digital broadcast receiver includes a recording means for recording a program of a channel designated for recording over a designated time zone for recording, and a first recording being reproduced. A second recorded program closest to the first recorded program before the first recorded program on the same channel as the program, and a third closest to the first recorded program after the first recorded program. Adjacent program information acquisition means for acquiring program information of the recorded program, and a video signal in which the program information of the second, first, and third recorded programs is sequentially arranged together with the image of the first recorded program Video signal output means.

  FIG. 9 is a flowchart showing the operation procedure of the adjacent program display process. In the adjacent program display process, when the viewer presses the adjacent program button 50 of the remote controller 40 during playback of the recorded program or presses one of the cursor buttons 45a to 45d, the control unit 13 detects it. Then, the adjacent program display process is started.

  In S11, the adjacent program information acquisition unit 25 uses the recorded information recorded in the recording device 18 to record a recorded program that is being played back by a previously recorded program on the time axis in the same channel as the recorded program that is being played back. The program information of the recorded program (time adjacent program) closest to the program is acquired, and the recorded program (time adjacent program) closest to the recorded program being played back in the subsequent recorded program on the time axis from the recorded program being played back The program information is acquired, and the meta information of the recorded program is acquired. The adjacent program information acquisition means 25 detects whether or not there is a previous recorded program than the previous recorded program, and further detects whether or not there is a subsequent recorded program than the subsequent recorded program. To do.

  In S12, the adjacent program information acquisition means 25 is a recorded program having a channel number closest to the recorded program being reproduced in the recorded program having the channel number smaller than the channel of the recorded program being reproduced in the same time zone as the recorded program being reproduced ( The program information of the channel adjacent program is acquired, and the recording of the channel number closest to the recorded program being played back is the same as the recorded program being played and the channel number of the recorded program being larger than the channel of the recorded program being played back. The program information of the program (channel adjacent program) is acquired, and the meta information of the recorded program is acquired. The adjacent program information acquisition means 25 detects whether or not there is a recorded program having a channel number smaller than that of the recorded program having the same time zone and a smaller channel number as the recorded program being reproduced. It is detected whether or not there is a recorded program having a channel number larger than that of a recorded program having the same time zone and a larger channel number as the program.

  In S <b> 13, the OSD data generation unit 26 generates OSD data of the adjacent program display 70 based on the meta information of the recorded program acquired by the adjacent program information acquisition unit 25. The display control unit 27 displays the OSD data of the adjacent program display 70 on the screen 9.

  Since the adjacent program information acquisition means 25 only retrieves and acquires program information of a maximum of four adjacent programs of a maximum of two time adjacent programs and a maximum of two channel adjacent programs for the recorded program being reproduced. Meta information can be acquired in a short time. The OSD data generation unit 26 can generate the OSD data of the adjacent program display 70 in a short time because the amount of information to be displayed is small.
