SMPTE Amendment 1:2011 to ST 352:2011

Prior to the revision of this document in 2010, SMPTE ST 352 was developed as a stand-alone document containing all of the information required to implement the payload ID for a wide range of video formats and interfaces.

As part of the 2010 revision, SMPTE ST 352 has begun the transition into a controlling standard in which the general format of the payload packet is defined, but the specific definition of the payload packet and its preferred horizontal and vertical position in the horizontal ancillary data space is contained in separate reference documents.

As part of this transition, all of the legacy payload definitions for existing formats and interfaces were included in normative Annex B. It is intended to remove specific language relating to these legacy formats and interfaces from SMPTE ST 352 over time as and when such legacy standards are revised to include the payload definitions directly.
