METHOD AND APPARATUS FOR MULTIPLE DESCRIPTION VIDEO CODING

摘要

An encoder includes a controller to determine whether macroblocks of a frame of video content are to be processed by intra-frame encoding or by predictive coding. The encoder includes a switch coupled to the controller. The encoder includes an intra-frame unit to receive the macroblocks via the switch when the controller determines to process the macroblocks by intra-frame encoding. The encoder includes a predictive unit to receive the macroblocks via the switch when the controller determines to process the macroblocks by predictive encoding. The encoder also includes a redundancy allocation unit coupled to the controller. The controller determines whether to process the macroblocks by intra-frame encoding or predictive frame encoding based on information received from the redundancy allocation unit.

1. An encoder comprising:
a controller to determine whether macroblocks of a frame of video content are to be processed by intra-frame encoding or by predictive coding; a switch coupled to the controller; an intra-frame unit to receive the macroblocks via the switch when the controller determines to process the macroblocks by intra-frame encoding; a predictive unit to receive the macroblocks via the switch when the controller determines to process the macroblocks by predictive encoding; and a redundancy allocation unit coupled to the controller, wherein the controller determines whether to process the macroblocks by intra-frame encoding or predictive frame encoding based on information received from the redundancy allocation unit.
