JPH06276454A - Automatic slave pattern display device - Google Patents

Abstract

PURPOSE:To provide the display device able to reserve all programs belonging to a genre by having only to enter a code of the genre of a desired program. CONSTITUTION:When a code of a reserved genre is entered from an entry section 12 to a control section 13, the control section 13 stores the code to a memory 16. The reservation genre code and a genre code from a tuner section are compared by a discrimination section 14, and when they are coincident, the control section 13 provides an output of a channel switching signal to a channel changeover section to switch a channel for a slave pattern. When the program is finished, the control section 13 sends a channel switching signal to the channel changeover section to replace the channel of the slave pattern with the original program and continues the program while a succeeding genre code is coincident with that from the tuner section.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television set or the like having a child screen display function.

[0002]

2. Description of the Related Art A program of a desired genre is broadcast by making it possible to simultaneously watch a plurality of channels on one television receiver, or by changing a channel of a sub-screen without changing a current program of a parent screen. There is a multi-screen method in which images of a plurality of channels are projected on one screen for the purpose of searching whether or not the screen is displayed. This system has the configuration shown in FIG. In the figure, the video signal from the antenna 1 is demodulated in one tuner unit 2 and output to the synthesizing unit 3 as a video signal of the parent screen. The video signal demodulated by the other tuner unit 4 is A / D converted by the A / D conversion unit 5 and written in the image memory 3. The written image data is read by a read timing signal from the controller 8 and output to the synthesizing unit 3.
The read timing signal from the controller 8 is
The D / A conversion unit 9 performs D / A conversion on the image data generated by the synchronization processing unit 7 and read from the image memory 6 by using the synchronization signal of the video signal of the tuner unit 4.
Output to the synthesis unit 3. The image signal of the child is switched by the synthesizing unit 3 at a predetermined timing, output to the display unit 10 and displayed on the main screen. However, conventionally, in order to search whether a program by genre such as movie, drama, or news is being broadcast on the child screen while watching the main screen by this method, the program of the child screen currently being watched is temporarily Since it was necessary to interrupt and switch the channel, it was necessary to switch the channel of the sub screen of the TV by pressing the sub screen channel button of the remote control device or the like.

[0003]

As described above, conventionally, when searching for a program, it was necessary to switch the channel of the television by pushing a channel button of a remote controller or the like, which is troublesome. It was troublesome and troublesome. In addition, in order to perform the above operation, there is a problem that the child screen that has been viewed until then must be temporarily suspended. In order to solve the above problems and make a reservation, the present invention only needs to input the code number of the program, and when the start time of the broadcast program of the desired genre is reached, the sub-screen channel can be switched to that channel. To provide.

[0004]

In order to solve the above problems, according to the present invention, when a code of a genre to be reserved is input from the input section to the control section, the control section stores this code in a memory. The genre code to be reserved and the genre code from the tuner section are compared by the discriminating section, and if they match, the control section outputs a channel switching signal to the channel switching section to switch the channel of the small screen to the matched program. When the program ends, the control unit sends a channel switching signal to the channel switching unit to switch the channel of the small screen to the original program and continue the program until the next genre code matches.

[0005]

With the above-described structure, in the automatic child screen display device according to the present invention, when a genre code of a specific program is designated by a key such as a remote controller, the genre code is stored in the memory. When a program broadcast belonging to is received, the channel is switched to that program.

Embodiments will be described in detail below with reference to the drawings. FIG. 1 is a block diagram of an automatic child screen display device according to the present invention, in which 12 is a code input section for inputting a code, and 13
Is a control section, 14 is a section for comparing the stored genre code with the genre code from the tuner section, 15 is a genre code memory for storing the contents of the program, and 16 is a memory for storing the genre code of the selected program. Is.
Reference numeral 17 is a part for displaying a message such as "program has started" on the sub-screen when a program of a desired genre is started in the display data generating section.

Next, the structure of the program memory for storing a list of programs in the figure will be described. Reference numerals 18 to 20 are data groups for storing program contents. Input unit 12 to control unit 1
When the code of the reserved genre is entered in 3, the control unit stores this code in the memory 16. The discriminator 14 compares the reserved genre code with the genre code from the tuner. If they match, the controller 13 outputs a channel switch signal to a channel switch (not shown) to match the sub-screen channels. Switch to the program you did. When the program ends, the control unit sends a channel switching signal to the channel switching unit to switch the channel of the sub-screen to the original program and continue the program until the next genre code matches.

Next, a method of reserving a desired genre broadcast program by the automatic child screen display device according to the present invention will be described. For example, a genre-specific code is transmitted by utilizing a portion (vertical blanking period) that cannot be effectively used as a video signal of a broadcast radio wave of a television station, such as is used for text broadcasting. This has a structure as shown in FIG. 3, and 41 in the figure is for identifying that the control data is a teletext signal.
2 is code data for each genre, 43 is check data for performing error correction, 44 is a succeeding teletext signal, and 45 is a horizontal synchronizing signal.

By providing a "update" code in the genre code, it is possible to monitor whether the content of the teletext program has been updated. When the code is updated, for example, "the program content is updated on the child screen. It is possible to know that the content of the desired teletext program has been "updated" while looking at the main screen, by viewing the main screen, and seeing the updated content by switching the channel to the teletext program. Can be done.

[0009]

As described above, according to the automatic child screen display device of the present invention, when the code of the desired genre is entered by the key of the remote controller or the like, the child screen is displayed when the program is started. Will switch to the screen of the desired genre, select the desired program in advance,
It is convenient and convenient to set reservations for the channel, broadcast start time, broadcast end time, etc. Also, it becomes convenient to automatically know information about whether the content of the teletext program has been updated.
