Abstract:
1. Method of assembling a decodable bitstream having a data structure fulfilling the requirements of a first data structure standard, the data of which bitstream include first main overhead data (VIDEO_TS) and multiple data units (DVD_Video VOBU, DVD_VR VOBU), each data unit containing first data unit overhead data (NV_PCK) according to said first data structure standard and encoded video data (V_PCK) and encoded or non-encoded audio data (A_PCK), wherein: said bitstream additionally includes second main overhead data (DVD_RTAV) such that said data structure of said bitstream fulfils also the requirements of a second data structure standard that is different from said first data structure standard; said data units (VOBU) additionally contain second data unit overhead data (RDI_PCK) according to said second data structure standard; said encoded video data (V_PCK) and said encoded or non-encoded audio data (A_PCK) are common to said first and second data structure standards.
