SMPTE RP 227-2007

The purpose of this recommended practice is to define a minimum set of rules for the carriage of a VC-1 elementary stream in MPEG-2 Systems protocols. In particular, this design is intended to provide a generic method for carrying a VC-1 video elementary stream over specific MPEG-2 transport streams, such as the ones defined by ATSC, DVB and SCTE. It is also intended to provide a generic means of carrying a VC-1 video elementary stream in an MPEG-2 Program Stream as used by the DVD Forum or the Blu-Ray consortium. One of the particular aspects of this Recommended Practice is to make sure that any private fields and private values needed in the mapping is properly scoped by an identifier to avoid any collisions or ambiguity in any of these delivery networks or media.
