ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a broadcast signal receiving device and method thereof in which genre data of the broadcast signal is detected thereby automatically being converted to an appropriate video and audio signal in accordance with a broadcasting mode.
2. Description of the Prior Art
A broadcasting station broadcasts various programs such as news, music concerts, sports, drama, education and documentary drama and transmits a broadcast signal over the air to a receiving system such as, a television set.
A televiewer selects a program which he wants to watch from various programs that are available and adjusts the conditions of video and audio to desired levels for the selected program.
However, it is often troublesome for the televiewer to adjust the conditions of video and audio signals each time the televiewer selects a program to watch. Accordingly, functions for adjusting the conditions of video and audio signal are often difficult to use, or it is unknown by the televiewer how to use these functions.
To overcome the problem as above-described, there is disclosed herein a device and method in which the televiewer selects a program, and appropriate conditions for audio and video signal level are automatically adjusted for various programs where audio and video levels are previously set in a memory.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a broadcast signal receiving device and method thereof in which genre data is detected to automatically convert to appropriate video and audio conditions for a given program.
To achieve the above object, the present invention provides a broadcast signal receiving method including 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 the decoding, and adjusting the current video and audio condition according to the control signal.
Furthermore, the present invention provides a broadcast signal receiving device including a tuner for selectively receiving a broadcast signal input through an antenna by a channel selection signal, a signal processing unit for processing the broadcast signal input from the tuner to be converted into an appropriate signal to comply with a set. Also included is a video and audio signal separation unit for separating the converted signal from the signal processing unit into a video signal and an audio signal. An audio signal processing unit adjusts the level of audio signal separated by the video and audio signal separation unit. A video signal processing unit adjusts the level of video signal separated by the video and audio signal separation unit. A genre data detection unit adjusts genre data of a program from the video signal separated by the video and audio signal processing unit. A control unit reads the video and audio control signals by decoding the detected data by the data detection unit and outputting the control signals to control the overall operation of the device, and a memory for storing control signals for the read video and audio signal are also included.
