Abstract

The transmission of any data is always subject to corruption due
to errors, but video transmission, because of its real time nature must
deal with these errors without retransmission of the corrupted data. The
error can be handled by using forward error correction in the encoder or
error concealment techniques in the decoder. The MPEG-2 compliant coder
described here uses steganography to transmit data for error correction
in conjunction with several error concealment techniques in the decoder.
The decoder resynchronizes more quickly with fewer errors than
traditional resynchronization techniques. This provides for a much
higher quality picture in an error-prone environment while creating an
almost imperceptible degradation of the picture in an error free
environment
