Abstract
Improved video coding is described to encode video data within a sequence of video frames. To this end, at least a portion of a reference frame is encoded to include motion information associated with the portion of the reference frame. At least a portion of a predictable frame that includes video data predictively correlated to said portion of said reference frame is defined based on the motion information. At least said portion of the predictable frame is encoded without including corresponding motion information and including mode identifying data. The mode identifying data indicate that the encoded portion of the predictable frame can be directly derived using at least the motion information associated with the portion of the reference frame.
