Abstract
Video data signals are encoded such that the encoded video data signal comprises at least a primary and at least a secondary video data signal. The primary and secondary video data signal are jointly compressed. The primary video data signal is compressed in a self-contained manner, and the secondary video data signal is compressed using data from the primary video data signal. The jointly compressed video data signal is split into separate bitstreams, at least a primary bitstream comprising data for the primary video data signal and at least a secondary bitstream comprising data for the secondary video data signal, whereafter the primary and secondary bitstreams are multiplexed into a multiplexed signal, and the primary and secondary signals are provided with separate codes.
