摘要： A method of encoding non-key frame data is disclosed. The method includes forming a bit stream from the data by arranging the bits from the data in a known order. The bit stream is interleaved to form an interleaved bit stream, and parity bits are generated for each of the bit stream and the interleaved bit stream. Bits are deleted from the generated parity bits dependant upon the bit plane of those bits, and an encoded bit stream is created from the remaining parity bits.
摘要翻译：公开了一种对非关键帧数据进行编码的方法。该方法包括通过以已知顺序排列来自数据的比特来从数据中形成比特流。比特流被交织以形成交错比特流，并且为比特流和交织比特流中的每一个生成奇偶校验位。从产生的奇偶校验位中删除比特，这取决于这些比特的比特平面，并且从剩余的奇偶校验位创建编码比特流。

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 method of removing an artefact from an image captured with a motion invariant camera is disclosed. The captured image is de-blurred using a spatially invariant blur kernel. An edge filter with a fixed offset is applied to the de-blurred image to identify the location of at least one artefact. A parameter is estimated based on a region either side of the identified location. The at least one artefact is removed from the de-blurred image using the parameter.

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 turbo encoder (1015) for forming parity bit data from the input frame (1005) 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). 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.

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).

摘要： A method and system (3000) of decoding video data using joint decoding (3100) of independently encoded sources (1010 and 3012) is disclosed. The method includes storing (1030) an initial estimate of first media data from a first source (1010). Second media data (3032) from a second source (3022) is received, with the second media data comprising parity bit data for correcting estimates derived from the first media data. The stored initial estimate is then retrieved, and the retrieved initial estimate and the received second media data are utilized to decode (3100) the media data.
