VIDEO DECODING SYSTEM HAVING COMPENSATION FUNCTION

摘要

The present invention relates to a video decoding system having a compensation function, the video decoding system comprising: one AD converter; a synchronized signal level detector for detecting a synchronized signal level using a digital signal output from the AD converter; a color burst level detector for detecting a color burst level using the digital signal output from the AD converter; a compensation apparatus for compensating the video level and the high frequency components of an analog signal by using information detected by the synchronized signal level detector and the color burst level detector, and for compensating and transmitting a synchronized signal level to the AD converter; and a decoding apparatus for outputting a digital component image signal (YCrCb) using the digital signal output from the AD converter.

1. A video decoding system which receives an analog signal, the video decoding system comprising:
one AD converter (Analogue to Digital Converter); a synchronized signal level detector configured to detect a synchronized signal level using a digital signal output from the AD converter; a color burst level detector configured to detect a color burst level using the digital signal output from the AD converter; a compensation apparatus configured to compensate a video level and a high frequency component and correct the synchronized signal level with respect to an analog signal using information detected by the synchronized signal level detector and the color burst level detector, and transmit the analog signal to the AD converter; and a decoding apparatus configured to output a digital component video signal (YCrCb) using the digital signal output from the AD converter.
