TH31287A - The stream format for the decoder suitable for MPEG. - Google Patents

Abstract

DC60 (27/07/41) MPEG decoder (14, 18, 22) in high definition television sets will Decodes and decompress MPEG encoded data to create extracted image pixel clusters. And it will include a motion compensation network (90 ...) connected to the frame memory (60) to generate data. The final decoded image pixels for displaying the decompressed MPEG data will be re-compressed by the machine. Repress many parallel signals (40, 42) before saving in frame memory. Each new compressor receives a stream of interlaced pixel data (24, 27; Fig. 5) and will be anticipated and compressing the interlaced pixel values (a, c) during each respective clock cycle (Fig. 20, 27). One of the new compressor (42) will be reduced power. In the data processing module Decreased when pixel data is sub-sampled (36, 38) before reprogramming. Sampled data The sub will be reordered (43) before re-recording. Multiple parallel decomposers (80, 82, 84) attached to frame memory provide pixel information to the control unit motion processing network (356, 360, 364, Fig. 23) It will ensure that uninterrupted interrupted information flows. To the decompression machine by duplicating the last usable data repeatedly when the data source is interrupted.
