DIGITAL VIDEO DECODING, BUFFERING AND FRAME-RATE CONVERTING METHOD AND APPARATUS

摘要

A digital video presentation system (30) is provided with a decoder (56) to decode full frame MPEG-2 video by a single method that applies regardless of buffer memory (42) and frame rate conversion considerations. A display control module (82) handles frame rate and field sequence in response to host configuration, particularly buffer memory (42) size and display type (NTSC or PAL), to host trick play command signals, and to information in the received bitstream. Pictures are decoded as buffer memory (42) for the decoded pictures becomes available, and picture display attributes are assigned and stored in a table (83), one string for each decoded picture.
