The first few steps of COBRA, and the molecular changes caused by each step to methylated and unmethylated CpG sites. Combined Bisulfite Restriction Analysis (or COBRA) is a molecular biology technique that allows for the sensitive quantification of DNA methylation levels at a specific genomic locus on a DNA sequence in a small sample of genomic DNA.

Typically, the soft output is used as the soft input to an outer decoder in a system using concatenated codes, or to modify the input to a further decoding iteration such as in the decoding of turbo codes. Examples include the BCJR algorithm and the soft output Viterbi algorithm.
Whereas a hard-decision decoder operates on data that take on a fixed set of possible values (typically 0 or 1 in a binary code), the inputs to a soft-decision decoder may take on a whole range of values in-between. This extra information indicates the reliability of each input data point, and is used to form better estimates of the original data.
On April 3, 2013, ATEME announced the availability of the first open source implementation of a HEVC software player based on the OpenHEVC decoder and GPAC video player which are both licensed under LGPL. [30] [31] The OpenHEVC decoder supports the Main profile of HEVC and can decode 1080p at 30 fps video using a single core CPU.
Hence, if we were lucky that these positions of the received word contained no errors, and hence equalled the positions of the sent codeword, then we may decode. If t {\displaystyle t} errors occurred, the probability of such a fortunate selection of columns is given by ( n − t k ) / ( n k ) {\displaystyle \textstyle {\binom {n-t}{k}}/{\binom ...
Once each order of the polynomial is decoded, the received word is modified accordingly by removing the corresponding codewords weighted by the decoded message contributions, up to the present stage. So for a rth order RM code, we have to decode iteratively r+1, times before we arrive at the final received code-word. Also, the values of the ...
CAVLC requires considerably less processing to decode than CABAC, although it does not compress the data quite as effectively. CAVLC is supported in all H.264 profiles, unlike CABAC which is not supported in Baseline and Extended profiles. CAVLC is used to encode residual, zig-zag ordered 4×4 (and 2×2) blocks of transform coefficients.
The Sigma Designs RealMagic ISA MPEG decoder card. RealMagic (or ReelMagic), from Sigma Designs, was one of the first fully compliant MPEG playback boards on the market in the mid-1990s. RealMagic is a hardware-accelerated MPEG decoder that mixes its video stream into a computer video card's output through the video card's feature connector.
