[0016]
In FIG. 1 and FIG. 2, the program information processing unit 21 receives a terrestrial broadcast received by an antenna or a signal transmitted through a satellite broadcast such as CS or BS although not shown in this example. Is done. For example, the transmission signal is obtained by superimposing program information, which is data for creating a program guide, in the form of a digital signal in a vertical blanking period of a video signal constituting a video of a program. This program information includes channel information such as broadcast station identification data, broadcast channel number, broadcast station name, broadcast date and time, program title, program information, program category, etc. for each program. The character information indicating the program title and the like is represented by a 2-byte character code defined by JIS (Japanese Industrial Standard) used in personal computers, for example. For example, the character code representing the English letter “A” is “2341”, and the character code representing the hiragana “na” is “244A”. In addition, program category information is added to each program broadcast as an identification code indicating the type of “movie”, “news”, “drama”, etc. for each program, and the channel information and the like are the same. .
[0017]
The signal input to the program information processing unit 21 is supplied to the signal separation unit 22. The signal separation unit 22 separates data information including various program information from the input signal, and the data information is output to the data extraction unit 23. Is done. The data extraction unit 23 extracts and decodes program information and channel information from the data information output from the signal separation unit 22, and outputs the program information and channel information to the data storage unit 25. The data storage unit 25 accumulates input program information and outputs it to the display data creation unit 26 when creating image data of the program guide. The display data creation unit 26 creates and outputs program guide image data based on the program guide information output from the data storage unit 25. At this time, the display data creating unit refers to the character code dictionary stored in the memory 27 and converts the character code included in the program information into the corresponding character display data. The program table image data output from the display data creation unit 26 is input to the image composition unit 11.
[0018]
The data storage unit 25 is a format in which broadcast time for each channel is represented using one axis as time and the other axis as a channel, as shown in newspapers and magazines, or a category in which programs are classified for each category regardless of the channel. Program information is stored in the form of a separate program list. The display form of the program guide displayed on the screen is determined by this storage form.
[0019]
The image synthesizing unit 11 synthesizes the video signal output from the video processing unit 9 and the image data of the information program guide output from the display data creating unit 26 into one image and outputs it. The output video is output from the video output unit 12 and displayed on the screen by the CRT 14.
[0020]
The control process 18 controls the video processing unit 9 and the information processing unit 21 in response to a command input from the control input unit 17 such as a remote control operated by the viewer. For example, the video processing unit 9 is controlled for image display size and image quality correction. Further, the information processing unit 21 is subjected to control of program information storage, editing, search, and display mode control or processing for each channel or category.
[0021]
When the command for displaying the program guide is received from, for example, the remote control 28 for the television receiver shown in FIG. 3, the display data creation unit 26 refers to the time information representing the current time from the clock device 24 and is currently broadcasting. And the program after that is displayed on the screen according to a predetermined format as shown in FIG. This command is issued, for example, when the program guide button 35 of the remote controller 28 is pressed.
[0022]
Here, the channels displayed in the program guide are displayed based on broadcast station identification data and broadcast channel number data as channel information obtained from the program information. In general, in the case of terrestrial broadcasting, a relay station is provided to cover a difficult viewing area. For example, when the key station is a VHF channel, the relay station converts a broadcast wave from the key station into UHF and retransmits the broadcast wave. In the area where the broadcast wave from the relay station is received, for example, 1ch is converted to 51ch, 2ch is converted to 52ch, etc., but the channel in the TV column of the newspaper displays the channel of the key station. Since there are many cases, the channel actually received is the UHF channel, but it may be more convenient to match the channel display with the channel display of the key station.
[0023]
4 and 5 show examples of channel setting menus on the television side. When the menu button 29 of the remote controller 28 is pressed, a channel setting screen is selected from several menus. In this example, “Channel button” is a number corresponding to the channel selection button 36 of the remote controller, “Channel” is the channel that is actually received, and “Display” is displayed on the screen when the channel selection button 36 is selected. The number “broadcast station identification number” is a number assigned in advance for each broadcast station obtained from the program information.
[0024]
FIG. 4 is an example of setting in an area where the 4ch of the key station can be directly received. That is, when “4” of the channel button 36 on the remote controller is pressed, the 4th channel is selected and “4” is displayed on the screen. Further, the program information processing unit 21 means that when the broadcast identification data obtained from the program information is 123, it is set to associate that the reception channel on the television side corresponds to 4ch. The same setting can be made for other channels. The control processing unit 18 stores the setting content in the memory 20 and transmits data in which the display number of each channel button is associated with the broadcast station identification number to the program information processing unit 21.
[0025]
Next, when the program information is received by the program information processing unit 21, the program content that matches the broadcasting station identification number in the program information is displayed for each channel, with one axis as a time and the other axis as a channel as shown in FIG. Display broadcast time. The channel number displayed at this time, for example, by displaying a number corresponding to the “display” set above, the program content selected by the user and the reception channel are associated with each other.
[0026]
FIG. 5 shows a setting example in an area where 4ch of the key station is converted to UHF54ch and retransmitted. That is, when “4” of the channel button 36 of the remote controller is pressed, 54 channels are selected and “4” is displayed on the screen. Further, the program information processing unit 21 means that when the broadcast identification data obtained from the program information is 123, it is set to associate that the reception channel on the television side corresponds to 54ch. As in FIG. 5, when the program information is received by the program information processing unit 21 with such settings, the program content that matches the broadcast station identification number from the program information is displayed on one axis as shown in FIG. The broadcast time for each channel is displayed with the other axis as the channel.
[0027]
Next, the case where the channel of the receiving device is selected from the channel number displayed in the program guide will be described. When the cursor movement keys 30 to 33 of the remote control shown in FIG. 3 are operated to move the cursor (black thick frame in FIG. 5) to the information display area of the desired program and then the decision button 34 is pressed, In this case, the TV display number data corresponding to the program is transmitted from the program information processing unit 21 to the control processing unit 18. The control processing unit 18 searches for a channel selection button that matches the received display number data, and selects the actual reception channel set there. In the case of a program of the previous time, the full text of the content title and other detailed information may be displayed at the top of the program guide.
[0028]
Here, in addition to using the channel number displayed in the program guide as the display number as in this example, it is also possible to display the reception channel as it is or to display the broadcast station name instead of the channel number. Needless to say, the remote control buttons 36 can be arranged in the order of numbers, and can be rearranged by the user freely changing the setting channel.
[0029]
【The invention's effect】
As described above, the present invention is a receiver for displaying a program guide, and can easily match the channel number of the program information with the channel number received on the television.
