Abstract
A forced intra-frame coding method for a video processing system includes steps by which video data is coded in the vertical direction of a frame while coding is performed to permit production of forcibly intra-frame coded macro block lines maintaining a predetermined vertical interval. Whenever the coding for respective frames is finished, the forcibly intra-frame coded macro block lines are shifted downward by one macro block, which allows the original image to be restored relatively rapidly. Furthermore, the coding direction of macro blocks is established as the vertical direction. Vertical coding permits the amount of data for respective macro blocks to stay uniform and, thus, facilitates control of an associated transmission buffer in the video processing system.

In a method of selectively intra/inter-frame coding video data divided into a plurality of blocks of a predetermined size, a forced intra-frame coding method comprising the steps of:
- (a) receiving blocks of a video frame in a vertical direction with respect to said video frame to produce respective received video data blocks;
- (b) selectively intra-frame and inter-frame coding said received video data blocks and forcibly intra-frame coding a plurality of horizontally adjacent blocks to produce a forcibly intra-frame coded block line;
- and
- (c) shifting respective positions of said forcibly intra-frame coded block line whenever one frame of video data is finished coding.
In a method of selectively intra/inter-frame coding video data divided into a plurality of blocks of a predetermined size, a forced intra-frame coding method comprising the steps of:
- (a) receiving a plurality of blocks corresponding to a video frame in a vertical direction with respect to said video frame to produce received video data blocks;
- (b) selectively intra-frame and inter-frame coding said received video data blocks while forcibly intra-frame coding horizontally adjacent blocks defining a forcibly intra-frame coded block line;
- and
- (c) shifting a respective position of said forcibly intra-frame coded block line corresponding to a next video frame whenever a present said video frame has been completely coded.
