摘要： A method (800) of performing distributed video encoding on an input video frame (1005), is disclosed. The method (800) forms a bit-stream from original pixel values of the input video frame (1005), such that groups of bits in the bit-stream are associated with clusters of spatial pixel positions in the input video frame (1005). The bit-stream is interleaved to reduce the clustering. The interleaved bit-stream is encoded to generate parity bits from the bit-stream according to a bitwise error correction method.

摘要： A system (100) for encoding an input video frame (1005), for transmitting or storing the encoded video and for decoding the video is disclosed. The system (100) includes an encoder (1000) and a decoder (1200) interconnected through a storage or transmission medium (1100). The encoder (1000) includes a module (1007) for mapping bit representations of component values of pixels of the input video frame (1005) to form mapped bit representations, wherein the Hamming distance of successive values in the mapped bit representations is at least two. The encoder (1000) further includes a turbo encoder (1015) for forming parity bit data from the mapped bit representations into a first data source (1120), and a sampler (1020) for down-sampling the input frame (1005) followed by intraframe compression (1030) to form a second data source (1110). The decoder (1200) receives data from the second data source (1110) to form an estimate for the frame (1005). The decoder (1200) also receivers the parity bit data from the first data source (1120), and corrects errors in the estimate by applying the parity bit data to the estimate. Each bit plane is corrected in turn by a turbo decoder (1260). A frame reconstruction module (1290) takes advantage of the Hamming distance of the mapped bit representation to compute final pixel values.

摘要： Methods (700, 800) for encoding an input video frame (1005) comprising a plurality of pixel values, to form an encoded video frame, are disclosed. The pixel values of the input video frame (1005) are down-sampled to generate a first stream of bits configured for use in subsequent determination of approximations of the pixel values. Samples from predetermined pixel positions of the input video frame (1005) are extracted to generate a second stream of bits configured for improving the determined approximations of the pixel values. A third stream of bits is generated from the input video frame (1005), according to a bitwise error correction method. The third stream of bits contains parity information, where the first, second and third stream of bits represent the encoded video frame.

The decoder (1200) also receivers the parity bit data from the first data source (1120), and corrects errors in the estimate by applying the parity bit data to the estimate. Each bit plane is corrected in turn by a turbo decoder (1260). The decoder determines how reliably a pixel value was decoded, too. Frame reconstruction module (1290) takes advantage of this and discards unreliably decoded pixels and replaces them with predicted pixel values.
