Abstract

PURPOSE:To enable a desired program to be selected even without confirming a program schedule table by providing a function to identify a program code attached on a broadcast single from a program code designated by a viewer and to select a broadcast program for which coincidence can be obtained between them. CONSTITUTION:An audience selects any one among (news), (sports), (movie), or (drama) provided on the equipment control operating part 5 or the remote operation control signal transmitter 6 of a receiver main body. By performing such operation, a microprocessor 4 inputs the information of a selected program to a program identification function part 7. And all the broadcast stations are detected with a signal detection function part 2 sequentially, and sent to the function part 7. The function part 7 detects the video signal of the broadcast signal and the data line of a program information code inserted to a prescribed horizontal scanning period in a vertical blanking period, and performs the identification processing of program information. When the information coincides with a designated program code, a processor 4 issues a command to select the broadcast station to receive the information to the function part 2. In such a manner, it is possible to designate the desired program even without confirming the program schedule table by the audience for that purpose.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a receiving broadcast station selection device used in a television receiver or the like, which selects a desired broadcast station from among a large number of broadcast stations.

[Conventional technology]

FIG. 2 is a system configuration diagram of a reception broadcasting station selection device conventionally employed in, for example, color television receivers manufactured by Mitsubishi Electric Corporation. In the figure, 1 is a broadcast signal antenna, and 2 is a signal detection function unit that detects a signal received by the broadcast signal antenna 1 and sends out a detected signal. Reference numeral 3 denotes a detection signal processing and reproduction function section, which outputs the detection signal as audio or video information. 4 is a microprocessor, 5 is a device control operation unit, 6 is a remote control signal transmitter,
The microprocessor 4 is operated in accordance with control signals from the device control operation section 5 and the remote control signal transmitter 6, and a command for the broadcasting station to be received is given to the signal detection function section 2.

Next, the operation will be explained. When a viewer selects a program of his or her choice, the viewer specifies a broadcasting station using the device control operation unit 5 of the receiver body or the remote control signal transmitter 6. In response to this operation, the microprocessor 4 gives a command regarding the broadcast station to be selected to the signal detection function unit 2. The signal detection function unit 2 matches the command from the microprocessor 4 from several types of broadcast signals received via the broadcast reception antenna 1. The broadcast signal is detected and sent to the detected signal processing and reproduction function section 3, where the detected signal is used to provide the viewer with the program selected by the viewer as audio output or video output.

[Problem to be solved by the invention]

Although the conventional reception broadcasting station selection device is configured as described above, it has the following problems.

■ When a viewer wants to watch a program of his or her choice, he or she must first check the program previews posted in newspapers, etc., check the broadcasting station, and then select the program.

Furthermore, if the viewer does not have a number notice table at hand, it is expected that the viewer will have to spend time and effort searching for the desired program while checking the program content each time he or she selects a channel.

This invention was made in order to solve the above-mentioned problems, and it is a receiving broadcasting station selection method that allows the viewer to select a desired program to some extent without having to take the trouble to check the program preview list. The purpose is to obtain equipment.

[Means to solve the problem]

The received broadcasting station selection device according to the present invention includes a program identification function unit that identifies and selects a designated program code by comparing a program code added to a broadcast signal with a program code designated by a viewer. It is something.

[Effect]

This invention includes a program identification function unit that compares and identifies the broadcast program code specified by the viewer with the broadcast program code added to the broadcast signal, and selects the matching broadcast program. The trouble of checking the program preview table and selecting a program can be reduced.

(Example〕 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a receiving broadcasting station selection device according to an embodiment of the present invention, and in the figure, numerals 1 to 6 are the same as a conventional receiving broadcasting station selection device. 7 is a program identification function section which inputs information from the microprocessor 4, outputs information to the microprocessor 4, and inputs a detected signal from the signal detection function section 2.

Furthermore, as an example of the program code added to the broadcast signal, FIG. 3 shows a waveform of the video signal of the broadcast signal, with a data line of the program information code inserted in the n-th horizontal scanning period of the vertical blanking period. In the figure, 10 is a data line.

The operation of the above embodiment will be explained. The viewer inputs a program code key, for example, r news j
Select one of Sports J R Movie 1 and R Drama 1. Through this operation, the microprocessor 4 inputs the information of the selected program to the program identification function section 7, while giving a command to the signal detection function section 2 to sequentially detect all broadcast stations stored in the microprocessor 4. It will be done.

The signal detection function unit 2 sequentially sends the detection output to the program identification function unit 7 in response to instructions from the microprocessor 4.The program identification function unit 7 detects the data line 10 as shown in FIG. 3 included in the detection output. The detected code is detected, the program information is coded, and the detected code and the program information input from the microprocessor 4 are compared and processed individually. If they are sequentially processed and match, the microprocessor 4 sends information on the broadcasting station to be received to the microprocessor 4.Based on this information, the microprocessor 4 instructs the signal detection function unit 2 to select the broadcasting station to be received and detected. As a result, the detected signal of the program specified by the viewer is provided from the signal detection function unit 2 to the viewer as an audio or video output via the detection signal processing and reproduction function unit 3.

〔Effect of the invention〕

As described above, according to the present invention, in a device incorporating this reception broadcasting station selection device, a viewer does not have to take the trouble of checking the program schedule 1i11 (but can specify a desired program within a certain range). This has the effect of improving the skill with which you can use the technique.
