Abstract

A method and a system conceal errors in video data transmission. An encoded current bitstream is received from a demodulator at a first decoder, which decodes the current bitstream. An encoded previous bit stream is received from a memoryat a second decoder, which decodes the previous bitstream. When it is determined that the current bitstream does not include an error, the decoded current bitstream output from the first decoder is selected, and when it is determined that the current bitstream does include an error, the decoded previous bitstream output from the second decoder is selected. The second decoder may operate in parallel with the first decoder.
