在微码控制下,再由数据包分离电路从数据流中分离出视频包与音频包,通过内部总线和存储器接口分别送入图像解包与音频解包电路。图像解包电路(视频解码)采用编码逆运算将MEPG—1视频压缩数据恢复成编码前的图像数据,并处理成8位数据总线的YUV格式(Y为亮度数据,U为色度数据,V为?
Under the control of the microcode, the video packet and the audio packet are separated from the data stream by the data packet separation circuit, and then sent to the image unpacking and audio unpacking circuits through the internal bus and the memory interface respectively. The image unpack circuit (video decoding) uses the code inverse operation to recover the MEPG-1 video compression data into the pre-encoding image data and processes it into the 8-bit data bus in YUV format (Y is luminance data, U is chrominance data, V for?
