AUDIO/VIDEO SIGNAL PROCESSING APPARATUS AND METHOD USING CPLD CHIP

摘要

PURPOSE: audio-video processing unit uses the CPLD chips from source using the audio/video signal that Complex programmable logical device CPLD (logic) chips and its method are provided to processing input, thus exports audio/video signal via output port. ;Analogue audio frequency/video that CONSTITUTION:A/D converters (130) are converted to input enters output digital audio/video signals by simulation input and port. Audio/video encoding/decoding chip (150) compresses or the digital audio/video signals of decompression input. Digital audio/video signals are converted to analogue audio frequency/video by a kind of D/A converter (140). One CPLD chips (160) output digital audio/video signals inputs a D/A converter, and the port and audio/video codec chip of numeral input and output are according to switching mode. ;The 2010 of copyright KIPO submissions
