Description: 本系统采用MEPG_4的SVP（Simple Visual Profile）视频解码。视频序列全部为矩形。所以不存在任意形状编码。视频序列按照视频对象层VOL（Video Object Layer）、视频对象平台VOP（Video Object Plane）、宏块MB（Macro Block）视顺序变成一串码流-MEPG_4 the SVP (Simple Visual Profile) Video decoder. All of the video sequence of rectangular. There is no arbitrary shape coding. Video sequences with video object layer VOL (Video Object Layer), Video Object platform VOP (Video Object Plane) Macroblock MB (Macro Block) as the sequence into a series of bitstream

Description: Abstract—In this letter, we propose an efficient decoding algorithm
for turbo product codes as introduced by Pyndiah. The proposed
decoder has no performance degradation and reduces the
complexity of the original decoder by an order of magnitude. We
concentrate on extended Bose–Chaudhuri–Hocquengem codes as
the constituent row and column codes because of their already low
implementation complexity. For these component codes, we observe
that the weight and reliability factors can be fixed, and that
there is no need for normalization. Furthermore, as opposed to
previous efficient decoders, the newly proposed decoder naturally
scales with a test-pattern parameter that can change as a function
of iteration number, i.e., the efficient Chase algorithm presented
here uses conventionally ordered test patterns, and the syndromes,
even parities, and extrinsic metrics are obtained with a minimum
number of operations.

Progressive Edge Growth (PEG) algorithm is presented. Edge
placement of the PEG algorithm is enhanced by use of the Sum-
Product algorithm in the design of the parity-check matrix. The
proposed algorithm is highly flexible in block length and rate.
The codes constructed by the proposed methods are tested in the
AWGN channel and significant performance improvements are
achieved. The flexibility of the proposed decoder optimisation
