DATA COMPRESSING DEVICE, DATA DECOMPRESSING DEVICE, AND DATA COMPRESSING/DECOMPRESSING APPARATUS
A data compressing device according to an embodiment includes a data cutting unit configured to divide continuously inputted data into W-bit data blocks and to output the data blocks in segments such that each of the segments is composed of N data blocks, and a compression-method determining unit configured to select, as a compression portion for each of the segments, a run length system, a flag system, or no compression, according to a ratio of data blocks of specific data in any of the segments. The data compressing device further includes an RL compression unit configured to execute, on any of the segments, a run length system of storing a consecutive amount of the specific data into compressed data, and a flag compression unit configured to execute, on any of the segments, a flag system of storing positional information of the specific data into compressed data.
Golomb-rice/EG coding technique for CABAC in HEVC
A system utilizing a high throughput coding mode for CABAC in HEVC is described. The system may include an electronic device configured to obtain a block of data to be encoded using an arithmetic based encoder; to generate a sequence of syntax elements using the obtained block; to compare an Absolute-3 value of the sequence or a parameter associated with the Absolute-3 value to a preset value; and to convert the Absolute-3 value to a codeword using a first code or a second code that is different than the first code, according to a result of the comparison.
Interleaved encoding of compressed attribute and color planes
An example embodiment may involve obtaining an ab pixel macro-cell from an image with one or more color planes, and an ab attribute macro-cell. The ab pixel macro-cell may contain 4 non-overlapping mn pixel cells, and the ab attribute macro-cell may contain 4 non-overlapping mn attribute cells. The pixels in the ab pixel macro-cell may be associated with respective color values. The example embodiment may also involve determining 4 attribute output values associated respectively with the 4 non-overlapping mn attribute cells. The example embodiment may further involve determining 1 to 4 color-plane output values for the non-overlapping mn pixel cells, and writing an interleaved representation of the 4 attribute output values and the determined color-plane output values.
System and method for serialized communication
A method for serializing communications in the computing field includes serializing input data into a serialized stream of symbols, based on one or more encodings, at a serializer, each symbol including a disparity code selected based on a running disparity (RD) of the serialized stream of symbols. The running disparity (RD) is tracked by setting the RD to an initial value, and then adding a disparity of each symbol to the RD to ensure the RD does not exceed a desired maximum, e.g., three. A positive disparity encoding or a negative disparity encoding of each symbol is selected for transmission based on the RD. The serialized data stream of symbols is transmitted along a data conduit, to a deserializer, in which the serialized data stream of symbols is deserialized to determine a corresponding bit value, for outputting decoded information in parallel form.

Adaptive compression of collection frames
A measurement transmission method is implemented in a meter and includes the steps of detecting at least one period of constant consumption formed by successive time intervals during each of which the consumption is equal to a constant value, and producing and transmitting a collection frame containing the measurement data associated with the time intervals of the measurement period, by replacing, for each constant consumption period, the measurement data associated with the successive time intervals of said constant consumption period with compacted data including a first data enabling it to identify the time intervals of the constant consumption period and a second data containing the constant value.
