Abstract: Data compression and decompression methods for compressing and decompressing data based on an actual or expected throughput (bandwidth) of a system. In one embodiment, a controller tracks and monitors the throughput (data storage and retrieval) of a data compression system and generates control signals to enable/disable different compression algorithms when, e.g., a bottleneck occurs so as to increase the throughput and eliminate the bottleneck.

Abstract: A system having one or more different asymmetric data decompression algorithms and a processor. A first asymmetric data decompression routine is configured to produce decompressed data with a higher data rate for a given data throughput than a second asymmetric data decompression routine of the plurality of different asymmetric data decompression routines. The processor is configured to analyze one or more data parameters from one or more data blocks containing video data and to select two or more different data decompression routines.

Abstract: A system and method including one or more asymmetric data compression algorithms is disclosed. A first asymmetric data compression algorithm of the one or more asymmetric data compression algorithms compresses data at a higher data compression rate than a second asymmetric data compression algorithm of the one or more asymmetric data compression algorithms. The system and method also include one or more processors that determine one or more data parameters from one or more data blocks and select one or more asymmetric data compression algorithms from among the one or more asymmetric data compression algorithms based upon, at least in part, the determined one or more data parameters.

The system and method include one or more data compression algorithms with at least one data compression algorithm from among the one or more data compression algorithms utilizing an asymmetric data compression. The system and method determine a type of data having one or more parameters, attributes, or values of the data from at least a portion of a data block; select one or more data compression algorithms from among the one or more data compression algorithms based upon the determined type of data and a throughput of a communications channel; and perform data compression with the selected one or more data compression algorithms on at least the portion of the data block.

Abstract: Method for coding a video signal using hybrid coding, comprising: reducing temporal redundancy by block based motion compensated prediction in order to establish a prediction error signal; performing quantization on samples of the prediction error signal or on coefficients resulting from a transformation of the prediction error signal into the frequency domain to obtain quantized values, representing quantized samples or quantized coefficients respectively; calculating a quantization efficiency for the quantized values; calculating a zero efficiency for a quantization, when the quantized values are set to zero; selecting the higher efficiency; and maintaining the quantized values or setting quantized values to zero, for further proceeding, depending on the selected efficiency.
