Sentence examples for by the decoder to from inspiring English sources
The amount of residual of every block of 4 × 4 pixels is used by the decoder to reconstruct the decoded MB, so this information will be available in the decoding process.
The encoder of the proposed DVC generates only a simple hash that is used by the decoder to select the corresponding VQ codeword.
In essence, the algorithm constitutes a low-complexity variant of the motion-compensated interpolation (MCI) method employed by the decoder to generate SI.
The most important problem that affects video quality is error propagation where an error in a reference frame is propagated by the decoder to all future reconstructed frames, which are predicted from the corrupted reference frame.
For this reason, in the case of block codes, the required parameters to perform the decoding operation are the number of inputs, denoted as k, the code word length, denoted as n, and a parity check matrix, denoted as H. Indeed, the matrix H will be used by the decoder to detect or/and to correct the errors.
These bits will be used by the decoder to correct a suitable estimate of the current image, which is produced using the available information such as images from the same camera at different time instants, or, for multiview systems, images from different cameras at the same instant.
In the first method, special information in the video packet header is exploited by the video decoder to isolate the effect of error propagation.
Let Lu 1 Net , Lu 2 Net , and L u Net be the extrinsic LLRs of the information bits sent by the network decoder to SISO decoder 1, SISO decoder 2, and SISO decoder R, respectively.
It uses partially decoded WZ frames generated by the WZ decoder to improve SI generation.
Taking advantage of the soft information fed back by the decoder, at each iteration the detector produces more reliable extrinsic information to be passed to the decoder itself: λ t ( n ) = ϕ t ( n ) - ξ t ( n ).
The vector denotes the samples received by the decoder at the channel output.
