Abstract
An embodiment of a method is disclosed for encoding a digital video signal including a first video sequence and a second video sequence jointly forming a stereo-view digital video signal. The method includes: subjecting the first video sequence to discrete cosine transform, quantization and run-length coding to produce a sequence of blocks of non-zero digital levels representative of the first video sequence, subjecting the second video sequence to discrete cosine transform, quantization, run-length coding and variable length coding to produce digital messages representative of the second video sequence, merging the bits of the digital messages into the sequence of blocks of digital levels by substituting the bits of the digital messages for respective Least Significant Bits of e.g. the last digital level in the blocks representative of the first video sequence to produce an encoded digital video signal representative of the first video sequence and the second video sequence.
