Robust and efficient compression/decompression providing for adjustable division of computational complexity between encoding/compression and decoding/decompression

摘要

Various embodiments of the present invention include compression/decompression methods, systems, and devices that adjust a division of a total computational complexity of compression and decompression between encoding and decoding. These embodiments include an encoder that encodes a received signal at a selectable level of computational complexity and a decoder that decodes a received, encoded signal at a selectable level computational complexity. Video-codec embodiments of the present invention may be incorporated into relatively inexpensive video-recording devices, including hand-held, video-recording consumer devices such as video recorders and cell phones.
