The stereoscopic image formats to be transported using this standard are the 4:2:2 and 4:4:4 image formats enumerated in SMPTE ST 425-3. Mapping structures for the video essence and ancillary data are as defined in SMPTE ST 425-3.
This standard also defines the carriage of ancillary data such as the audio data, the audio control packets, the payload identifierand the time code.
It is not necessary for implementations to include support for all image formats, nor is it a requirement to support both mapping modes to conform to this standard. Implementers are encouraged to indicate supported formats and supported mapping modes in commercial publications.
