Compression / decompression for efficient robust to provide an adjustable distribution of the computational complexity between the decryption / decompression and encoding / compression

摘要

To provide a compression / decompression and efficient robust to provide an adjustable distribution of computational complexity between the decryption / decompression and [challenge] encoding / compression. Various embodiments of the present invention comprises, adjust the distribution of the (2202, 2204) total computation complexity of the compression and decompression of between (2208,2210) and decoding coded (2206,2212) compression / decompression method to, systems, and devices. These embodiments include an encoder for encoding computational complexity of the selectable level received signal, and a decoder for decoding with computational complexity of selectable level encoded signal received . Embodiment of the video codec of the present invention may be incorporated includes a hand-held video recording consumer device such as a mobile phone and a video recorder, a relatively inexpensive video recording device.
