Independent motion compcnsation loops are maintained for two descriptions i n the encoder. In each description, one slicc group is encoded as main information, while the other slice group is encoded very coarsely, as redundancy. to keep basic information. This coarse slice
more » ... This coarse slice group can be encoded using normal encoding with coarse quantizer, or using predicted motion vectors by the main slice gwup. Mode decision is made to select best encoding method. Results show that our scheme works very well and keeps subjective quality very good for middle and higher bitrate. Redundancy and side quality can be controlled by changing parameters o f coarsely coded slice group, unlike some othcr M D C methods with fixed redundancy.
