METHOD FOR SIMULTANEOUSLY ENCODING MACROBLOCK GROUPS OF FRAME

摘要

A first frame associated with a video stream is in a prior sequence than a second frame of the video stream. Each of the first frame and the second frame has a plurality of groups, and each of the groups contains a plurality of macroblocks. A plurality of encoding procedures of the groups of the second frame are simultaneously performed to encode the second frame into a plurality of strings of data, and encoded data of the second frame is outputted by the encoder according to the strings of data. Since a plurality of groups of the macroblocks in the second frame are simultaneously encoded, the encoder has a high efficiency of encoding the video stream.

1. A method for simultaneously encoding groups of macroblocks of one of frames of a video stream by an encoder, a first frame associated with the frames of the video stream being in a prior sequence than a second frame of the video stream, each of the first frame and the second frame comprising a plurality of groups, each of the groups containing m×n macroblocks arranged in m rows and n columns, and m and n being integers greater than 1, the method comprising:
simultaneously performing a plurality of encoding procedures of the groups of the second frame to generate a plurality of strings of data, wherein each of the encoding procedures is configured to encode a corresponding one target group of the groups of the second frame and comprises:
performing a plurality of macroblock comparison procedures of the target group to generate a plurality of sub-strings of data, wherein each macroblock comparison procedure is configured to compare a corresponding one target macroblock of the m×n macroblocks of the target group with each macroblock of a macroblock set associated with the target macroblock, and the macroblock set comprises a reference macroblock of a reference group of the first frame; andgenerating one of the strings of data according to the sub-strings of data; and outputting encoded data of the second frame by the encoder according to the strings of data.
