The channel selection program information acquisition unit 813 includes channel selection channels recognized by the channel selection channel recognition unit 811 and date / time information acquired by the date / time information acquisition unit 812 from the EPG information stored in the EPG information storage device 62. Based on the above, channel selection program information relating to a program currently broadcast on the channel selected by the viewer is acquired.
In the present embodiment, an identification number and a program name are acquired.

When the channel selection program information is acquired, the channel selection program information storage step S4 is executed by the memory 82.
The memory 82 stores an identification number among the channel selection program information acquired by the channel selection program information acquisition unit 813.
In addition, when the memory 82 overflows by storing the identification number, the old information is deleted in order.

When the identification number is stored in the memory 82, the channel selection program information comparison unit 814 executes the channel selection program information comparison step S5.
The channel selection program information comparison unit 814 compares whether or not the identification number previously stored in the memory 82 has the same identification number as that acquired by the channel selection program information acquisition unit 813. .

When the identification numbers are compared by the channel selection program information comparison unit 814, the display control unit 815 executes the display control step S6.
The display control unit 815 changes the display state of the channel selection program information to be displayed on the display of the image display device 9 based on the comparison result by the channel selection program information comparison unit 814, and then the channel selection program information acquisition unit 813. The channel selection program information acquired by the above is superimposed on the television video via the video output device 72 and displayed on the display of the image display device 9.

For example, in this embodiment, the display control unit 815 sets the display color to “yellow” when the same identification number exists as a result of comparison by the channel selection program information comparison unit 814 (S61). If it does not exist (S62), the display color is set to "white" (S63).
Then, the display control unit 815 superimposes the channel selection program information, in this embodiment, the program name, together with the channel number information related to the channel selection, on the television video via the video output device 72. It is displayed on the display (S64).

Next, the display control unit 815 starts a timer (S65), and monitors the timer until the channel selection operation detecting means 4 detects a channel selection operation by the viewer or a predetermined time elapses (S65). S66, S67). At this time, when the channel selection operation detecting means 4 detects the channel selection operation by the viewer (S66), the display control unit 815 detects the channel number information displayed on the display of the image display device 9 and the program. The name is deleted (S68). Then, the channel selection channel recognition unit 811 executes the channel selection channel recognition step S1 again.
On the other hand, when the predetermined time has elapsed (S67), the display control unit 815 deletes the channel number information and the program name (S69).

Next, the state of the display of the image display device 9 when the viewer switches the channel will be described in detail with reference to FIG.
First, it is assumed that the viewer is watching “Drama 21” of Ch (channel) 2 (G1).

Next, when Ch3 is selected by the viewer, for example, if the identification number of “Movie [Patman]” broadcast on Ch3 is “1”, the memory 82 stores “1”. If the identification number of “Drama 21” broadcast on Ch2 is “0”, the memory 82 stores “0” by the channel selection operation of the previous channel.
Here, since the identification number “1” of “movie [patman]” is different from the identification number “0” previously stored in the memory 82, the same identification number does not exist, so the display control unit 815. Displays the channel number information and the program name in “white” (G2).

Similarly, when Ch4 is selected by the viewer, for example, if the identification number of “News Stop” broadcast on Ch4 is “2”, the memory 82 stores “2”.
Here, since the identification number “2” of “news stop” is different from the identification numbers “0” and “1” previously stored in the memory 82, the same identification number does not exist. The control unit 815 displays the channel number information and the program name in “white” (G3).

Next, when Ch3 is selected again by the viewer, for example, if the identification number of “movie [patman]” broadcast on Ch3 is “1”, the memory 82 stores “1”. .
Here, the identification number “1” of “Movie [Patman]” is the same as the identification numbers “0”, “1”, and “2” previously stored in the memory 82. Therefore, the display control unit 815 displays the channel number information and the program name in “yellow” (G4).

Next, when Ch4 is selected again by the viewer, for example, if the identification number of “others in winter” broadcast on Ch4 is “3”, the memory 82 stores “3”.
Here, since the identification number “3” of “others in winter” is different from the identification numbers “0”, “1”, and “2” previously stored in the memory 82, the display control unit 815 displays The number information and the program name are displayed in “white” (G5).
In Ch4, “News Stop” was broadcast before, but when Ch4 is selected again by the viewer, the “News Stop” broadcast ends, and “Winter Other” is displayed. Since it is broadcast, the identification number is different.

The television receiver 1 according to the embodiment has the following effects.
(1) The identification numbers previously stored in the memory 82 are compared with each other to determine whether or not the same identification number as the identification number acquired by the channel selection program information acquisition unit 813 exists. Since the channel number information displayed on the image display device and the display color of the program name are changed to “yellow” or “white”, the viewer can easily determine whether the program has already been viewed when selecting a channel. Can be judged.

(2) Since the comparison is based on the identification number, even if the same channel is selected, if the program being broadcast is different, the display color is changed as a program that has not yet been viewed. be able to.
(3) Since the channel number information of the channel selected by the viewer and the program name are superimposed on the television video via the video output device 72 and displayed on the display of the image display device 9, the selected program There is no need to secure an area for displaying information, and the visibility of television images can be improved.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, whether or not the same identification number as the identification number acquired by the channel selection program information acquisition unit 813 exists in the identification numbers previously stored in the memory 82 is compared by the program name or the like. In short, it may be channel selection program information that allows the viewer to determine whether the program has already been viewed.

The memory 82 stores channel selection program information every time the channel selection operation detecting means 4 detects a channel selection operation by the viewer. For example, after the channel selection operation by the viewer is detected, the memory 82 stores a predetermined channel information. The channel selection program information may be stored when the time has elapsed, in short, as long as it is possible to determine whether or not the program has already been viewed by the viewer.
In addition, the display control unit 815 has changed the display state of the channel selection program information by changing the display color. However, the display control unit 815 may change the display state to semi-transparent display, flashing display, or the like. It suffices as long as it can be easily determined whether or not the program has been played.

Further, the channel number information of the channel selected by the viewer and the program name are superimposed on the television video via the video output device 72 and displayed on the display of the image display device 9, but they are displayed in different areas. Each may be displayed. In short, it is only necessary that the television video signal and the channel selection program information can be displayed on the display of the image display device 9.
The channel selection program information displayed on the display of the image display device 9 is only the channel number information and the program name. However, for example, the program content and genre may be displayed. Information corresponding to the signal may be displayed.

It is a block diagram of the television receiver in embodiment of this invention. It is a block diagram which shows the control apparatus of the television receiver.
