METHOD AND SYSTEM FOR ENCODING A VIDEO DATA SIGNAL, ENCODED VIDEO DATA SIGNAL, METHOD AND SYSTEM FOR DECODING A VIDEO DATA SIGNAL

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 (BSS) 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 (0x1B, 0x20). La presente invenci?n se refiere a se?ales de datos de video que se codifican de modo que la se?al de datos de video codificada comprende al menos una se?al de datos de video primaria y al menos una secundaria. Las se?ales de datos de video primaria y secundaria se comprimen conjuntamente. La se?al de datos de video primaria se comprime en una manera auto-contenida, y la se?al de datos de video secundaria se comprime usando datos de la se?al de datos de video primaria. Las se?al de datos de video comprimida conjuntamente se divide (BSS) en corrientes de bits separadas, al menos una corriente de bits primaria que comprende datos para la se?al de datos video primaria y al menos una corriente de bits secundaria que comprende datos para la se?al de datos de video secundaria, tras lo cual las corrientes de bits primaria y secundaria son multiplexadas en una se?al multiplexada, y las se?ales primaria y secundaria se proporcionan con c?digos separados (0c1B, 0x20).
