Publisher: SMPTE — White Plains, NY, USA
Suite/Collection: Television
Doc Type: Standard (ST)
Pages: 1–13
Abstract: This standard provides the mechanisms necessary to facilitate the transport of packetized data over a synchronous data carrier. The HD-SDTI data packets and synchronizing signals provide a data transport interface which is compatible with SMPTE 292M (HD-SDI) such that it can be readily used by the infrastructure provided by this standard. — The standard uses a dual-channel operation where each line carries two data channels each forming an independent HD-SDTI data transport mechanism. The two channels are word-multiplexed onto the HD-SDI stream such that one line-channel occupies the C data space and the other line-channel occupies the Y data space. — The standard provides for a baseline operation which supports a constant payload length per line-channel having a maximum payload data rate up to approximately 1.0 Gb/s. It further provides for an extended operation which supports a variable payload length through the advancement of the SAV sequence to ensure a constant payload data rate regardless of the HD-SDI frame rate. — The HD-SDTI protocol is compatible with SMPTE 305M. — Additional documents shall be used to describe the payloads of particular applications of this standard including details of the data formatting and other parameters such as compression and error correction, if applicable.
