'memory architecture for a multi-format video signal processor'

摘要

"MEMORY ARCHITECTURE FOR A MULTIPLE FORMAT VIDEO SIGNAL PROCESSOR" This is a video decoder (10) that transcodes video data from various input formats into a predetermined output format. The input data can be standard definition data (NTSC or PAL) or compressed MPEG2 data. Standard definition data is reorganized in block format to be compatible with the single display processor (40) of the decoder (10). The display processor processes selectively and conducts both data in MPEG2 format and data in non-MPEG2 format to a display device. A block-based frame memory (20) stores both MPEG2 and non-MPEG2 pixel block data, as well as standard definition data in raster format during processing.
