Abstract
The present invention relates to a broadcast signal receiving device and method thereof in which genre data of a broadcast signal is detected to thereby automatically be converted to an appropriate video and audio signal. According to the present invention a broadcast signal including genre data is processed for being converted into an appropriate signal according to a control signal previously stored in a memory thereby to provide a best condition for the video and audio. Furthermore, the televiewer can change data for the video and audio established to fit the genre data at the time of manufacturing the set, and can adjust the current program being broadcasted to a certain data.
Claims17
A method for automatically adjusting video and audio levels, comprising the steps of:
- receiving a broadcast signal through an antenna from a broadcasting station;
- detecting genre data of a program from the broadcast signal;
- decoding the detected genre data of the program;
- reading a video and audio control signal corresponding to the result of decoding;
- and
- adjusting the video and audio levels according to the control signal.
A broadcast signal receiving device having automatically adjusted video and audio signal levels, comprising;
- receiving means for receiving a broadcast signal from a broadcasting station;
- means for detecting and decoding genre data of a program from the broadcast signal;
- means for generating a video and audio control signal corresponding to the result of the decoded genre data;
- and
- adjusting means for adjusting the video and audio levels according to the control signal.
A broadcast signal receiving device having automatically adjusted video and audio signal levels, comprising:
- a tuner for receiving a broadcast signal;
- a signal processing unit for processing the broadcast signal inputted from the tuner to be converted into an appropriate signal to comply with a set;
- a video and audio signal separation unit for separating the converted signal by the signal processing unit into a video signal and an audio signal;
- an audio signal processing unit for adjusting the level of audio signal separated by the video and audio signal separation unit;
- a video signal processing unit for adjusting the level of video signal separated by the video and audio signal separation unit;
- a genre data detection unit for detecting genre data of a program from the video signal separated by the video and audio signal processing unit;
- a control unit for reading video and audio control data by decoding the detected data by the data detection unit and outputting control signal to control the overall operation of the device;
- and
- a memory for storing a control signal for the read video and audio signal.
