scope:
This standard defines the digital video coding for 4:4:4 and 4:2:2 color spaces and a virtual parallel interface for 525/625-line interlaced systems. Two luma sampling rates are defined: 13.5 MHz and 18 MHz. The virtual parallel signal interface format is required as the source for the 10 bit serial interface defined in SMPTE ST 259.
Annex D covers video coding for the 4:4:4:4 member of the family, including multiplexing details for ―dual channel" operation.
