There was a need to switch.

  Further, when a program is selected from the back program guide and the channel is switched, there is a problem that viewing is interrupted for the currently viewed program.

  In view of the above-described problems, the present invention aims to display information on the back program as well as the back program table so that the viewer can appropriately display the back program together with the currently viewed video. An object of the present invention is to provide a television receiver or the like that can select a back program.

  In order to solve the above problems, a television receiver according to a first aspect of the present invention is a television broadcast receiving means for receiving a television broadcast signal, and a channel for selecting a predetermined channel from a plurality of channels receivable by the television broadcast receiving means. Selecting means; program display means for displaying a program of a channel selected by the channel selection means and received by the television broadcast receiving means; and an electronic program guide for extracting electronic program guide data from the television broadcast signal Displayed by the data extraction means, the back program guide display means for generating and displaying the program guide including the time of the currently viewed program from the electronic program guide data extraction means, and the back program guide display means. Back program selection means for selecting a program of one channel from the back program table as a selected back program, and the program display unit Is characterized by having a counterprogram selected by the off-screen program selection means, the off-screen program display means for displaying said viewing program on the same screen.

  According to a second aspect of the present invention, in the television receiver according to the first aspect, the program display means displays the viewing program, the back program, and the back program guide on the same screen. To do.

  According to a third aspect of the present invention, in the television receiver according to the first or second aspect, the television receiver includes a plurality of tuners, and the tuner that receives the back program receives the viewing program. The tuner is different from the tuner.

  According to the present invention, the program corresponding to the selected channel is displayed as the viewing program, and the back program selected from the back program table including the time of the currently viewed program is displayed. It will be. Therefore, the viewer can view the back program as well as the currently viewed program. Furthermore, since the back program can be visually recognized, it becomes possible to appropriately select the back program at a desired timing.
