Abstract:
1. An encoder comprising: a first module responsive to a video frame, the first module configured to divide the video frame into macroblocks; a mode selection element configured to select each of the macroblocks for intra-frame coding mode (I-mode) encoding or for predictive coding mode (P-mode) encoding; an I-mode module configured to encode a first macroblock that is selected for I-mode encoding by coding color values of the first macroblock into an I-mode first description of a multiple description coding scheme and into an I-mode second description of the multiple description coding scheme; and a P-mode module configured to encode a second macroblock that is selected for P-mode encoding by coding both a motion vector and an error into a first P-mode description and into a second P-mode description by predicting the second macroblock based on a previously encoded frame.
