Abstract

At least one region of each video frame is designated for intra encoding. One or more regions of each video frame are designated for inter encoding. One or more motion vectors are selected for each region designated for inter encoding, wherein at least one motion vector is a non-zero motion vector. The plurality of video frames are encoded in accordance with the designation of regions for intra encoding, the designation of regions for inter encoding, and the selection of motion vectors, wherein the designation of regions for intra encoding and the selection of motion vectors are adapted to ensure error recovery during decoding of the encoded video frames.
