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.

Method for simultaneously encoding macroblock groups of frame

A first request and a second request are received from a first client terminal and a second client terminal respectively. In response to the first request and second request, a first set of predictions is generated by predicting macroblocks of frames of a video stream. In response to the first request, a first set of quantized transform coefficients is generated by transforming the first set of predictions, and a first coded video stream is generated by coding the first set of quantized transform coefficients. In response to the second request, a second set of quantized transform coefficients is generated by transforming the first set of predictions, and a second coded video stream is generated by coding the second set of quantized transform coefficients. Finally, the first coded video stream is transmitted to the first client terminal, and the second coded video stream is transmitted to the second client terminal.
