Description

Method for warning at generat cause of broadcasting

The present invention relates to a method of warning a signal when a broadcast station breaks down or a broadcast error due to a broadcast error. In particular, a signal is struck due to a broadcast accident that occurs frequently in a small private broadcast station, and accordingly the television receiver side The present invention relates to a warning method for a broadcast accident to notify a user that a broadcasting accident has occurred in a broadcasting station providing a source to a broadcasting channel that is currently being received.

In general, a large number of private stations operate in developed countries such as Europe and the United States in terms of providing viewers with a variety of attractions. Therefore, viewers watch a wide variety of programs and have a wide variety of programs.

However, as too many private broadcasters are operating, there are also natural private broadcasters, which are often broadcast accidents.

In general, when a broadcast accident occurs, the broadcasting station broadcasts a message instructing the user to wait for a while due to a broadcast accident. As the above-mentioned small broadcast station does not perform such a guide broadcast, the viewer may have a problem with a television receiver or a broadcast accident. It was often pointed out as a problem because it often occurred without knowing cognition.

Also, in the case of a broadcast accident, the broadcast station usually transmits music or still images (beautiful scenery or character screens) so that the viewer is free, but the small station does not provide such services. The problem of being neglected has arisen.

An object of the present invention for solving the problems of the prior art described above is that the user is currently being received by the user when a signal is lost due to a broadcast accident that occurs frequently in a small private broadcasting station, and therefore must be unconditionally waiting on the television receiver side. The present invention provides a warning method for a broadcast accident to notify a user that a broadcasting accident has occurred in a broadcasting station providing a source to a broadcasting channel.

A feature of the present invention for achieving the above object is a warning method in a television receiver capable of retrieving a broadcast program information code inserted within a vertical blanking period of a broadcast signal, wherein a predetermined number of still pictures and warning phrases are specified. A first step of storing in a memory means, a second step of determining whether a synchronization signal is detected by searching for a synchronization signal of a broadcast signal currently tuned and received, and when the synchronization signal is not detected in the second step A third step of determining whether a code indicating a broadcast accident exists by searching for a program information code, and a still picture and a warning stored in the memory means through the first step if it is determined that the broadcast accident is found in the third step. And accessing the phrase and then displaying the fourth step.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a schematic block diagram of a television employed in accordance with a preferred embodiment of the present invention, which includes a key input unit 10, a microcomputer 20, a tuner unit 30, a video / audio signal processing unit 40, and an OSD unit. 50, a monitor 60, a speaker 70, a VPS decoder 80, and a memory 90.

In this configuration, the key input unit 10 is provided with a plurality of keys including a reservation selection key for selecting a reservation category, a movement key for moving a category, a confirmation key for finally selecting a category, and the like. It outputs a corresponding key signal, and transmits / receives a key signal carried on a predetermined infrared carrier using a remote controller that can be input at a remote place and applies it to the microcomputer 20 which will be described later.

The microcomputer 20 is driven based on the constant power supply from the memory 80 to be described later, and the tuner 30, the video / audio signal processor 40, and the OSD are driven based on the key signal from the key input unit 10. By selectively controlling the unit 50 to control the overall operation of the television, and when a reservation selection key signal is applied from the key input unit 10, for example, classified into category information included in the broadcast program information based on the VPS, On the OSD unit 50, a category screen for selecting a desired category, including all categories such as news, drama, sports, and the like, is controlled by the OSD unit 50, and based on the moving key signal and confirmation key signal from the key input unit 10 Control to store the selected category in an internal memory (not shown).

In addition, when the category is selected as described above and the reserved wake-up time (power-on time) and the scheduled sleep time (power-off time) are set by the user through a separate routine, the internal timer (not shown) is shown. Compares the current time with a preset scheduled weather time (power on time), and when the scheduled weather time arrives, stored program information (eg, channel, category, broadcast start / end time, viewing grade, etc.) based on the VPS. (C) search for a channel on which a broadcast program corresponding to a category selected and stored by the user is broadcast, and perform power-on control of the television with the found channel.

Meanwhile, the tuner unit 30 outputs a broadcast signal received by being tuned to a corresponding channel corresponding to the control of the microcomputer 20.

In addition, the video / audio signal processing unit 40 separates the broadcast signal applied from the tuner unit 30 into a video and audio signal under the control of the microcomputer 20 and processes the video signal into a signal capable of display and output, respectively. Are output to the OSD unit 50, and audio signals to the speaker 70, respectively.

In addition, the OSD (On Screen Display) unit 50 is a device for processing text on a television screen, and reads a text signal corresponding to the control of the microcomputer 20 to display the video / audio signal to be displayed at a predetermined screen position The synthesizer outputs a video signal or a blue-back signal (the background color can be set to a color other than blue) applied from the processing unit 40.
