ST 322:2004 - SMPTE Standard - For Television — Format for Transmission of DV Compressed Video, Audio and Data over a Serial Data Transport Interface

This standard specifies the data structure and the transmission format of DV compressed video, audio, and data over a serial data transport interface (SDTI [SMPTE 305.2M]). The standard is a combination of video, audio, subcode, and control data optimized for the connection between DV-compliant VCRs and disk systems. It ensures high-speed data stream transfer up to five times faster than real time. The video, audio, and subcode data comply with IEC 61834-2 for both 525/60 and 625/50 systems. The bit stream consists of 77-byte DIF data blocks, which are common to other DV based signals. The DIF blocks are mapped onto SDTI using a frame-bounded algorithm preserving ease of manipulating the video and audio data. — The layers of signal processing and related standards are shown in figure 1. — NOTE – For descriptions of the SDTI, refer to SMPTE 305.2M, and for descriptions of video, audio, and subcode data, refer to IEC 61834-2. The standard corresponds to data type [241
