摘要:
A system and method is disclosed for converting a codec of image data. The system comprises a syntax converter for selectively converting first image data having a first syntax into second image data having a second syntax in response to a comparison of the first image data and the second image data, and a decoder for decoding a bit stream outputted from the syntax converter.

A streaming contents recording method of a mobile terminal including comparing a length of streaming contents with a remaining memory capacity of the mobile terminal, and recording the streaming contents by omitting a specific frame type if the length of the streaming contents is greater than the memory capacity. Further, the omitted specific frame types include a B-frame type or a B-frame type and a P-frame type.
摘要:
A method for judging a lost block characteristic in a video processing system including certifying whether a lost block exists among transmitted video blocks, calculating a temporal difference cost1 between neighborhood pixels of the lost block in a present frame and a previous frame, and calculating a motion vector distribution value cost2 of peripheral blocks of the lost video block. The method also includes comparing the temporal difference cost1 and the motion vector distribution value cost2 with preset threshold values, and determining a characteristic of the lost block based on a result of the comparison. The automatically judged characteristic of the lost block is utilized as information for recovering the lost block to thereby reproduce a recovery video close to the original video.
摘要:
A method for extracting a macro block at a high speed is disclosed to re-set a motion vector in a DCT (Discrete Cosine Transform) region. A macro block is extracted by using an overlap phenomenon where a previously extracted macro block information and macro block information to be currently extracted overlap with each other, so that the amount of calculation can be considerably reduced.
