Method and apparatus for concealing errors in a bit stream

摘要

Bit streams are divided on a block-by-block basis based on information of bit numbers and a parity bit added to each bit stream is checked to generate a switching signal. Either each bit stream or a proximate bit stream for each bit stream is selected as an optimum bit stream based on the switching signal, wherein the proximate bit stream is generated based on degrees of proximity for reference bit streams spatially adjacent to each bit stream, and the optimum bit stream is decoded to generate decoded data on a block-by-block basis.
