Video Payload Identification Codes SMPTE ST 352

SMPTE Registration Authority, LLC is the registration authority for SMPTE ST 352 Video Payload Identification Codes for Serial Digital Interfaces

This standard, available here, is the specification of a 4-byte payload identifier which may be added to digital interfaces for the purpose of identifying the video payload. The payload identifier is applicable to all serial digital interfaces and all payloads that produce a directly viewable image on a display device. Furthermore, the viewable ima ge must be a recognizable representation of the source image content. 

The standard defines how the payload identifier is placed into a 10-bit ancillary data packet according to SMPTE ST 291

It also specifies the repetition rate of the ancillary data packet, and provides the preferred horizontal and vertical location for the placement of the packet in different digital interfaces. 

The standard also includes definitions for the interpretation of each byte of the 4-byte payload identifier although the values for many video payloads can have custom definitions. 

The standard also defines the Video Payload Identification Code assignment process and associated on-line register for Byte 1 Values. 

See Annex A for details on how to register new values.
