SMPTE 314M

Description

SMPTE 314M – Television – Data Structure for DV-Based Audio, Data and Compressed Video – 25 and 50 Mb/s

This standard defines the DV-based data structure for the interface of digital audio, subcode data, and compressed video with the following parameters: 525/60 system – 4:1:1 image sampling structure, 25 Mb/s data rate; 525/60 system – 4:2:2 image sampling structure, 50 Mb/s data rate; 625/50 system – 4:1:1 image sampling structure, 25 Mb/s data rate; 625/50 system – 4:2:2 image sampling structure, 50 Mb/s data rate. This standard does not define the DV-compliant data structure for the interface of digital audio, subcode data, and compressed video with the following parameters: 625/50 system – 4:2:0 image sampling structure, 25 Mb/s data rate. The compression algorithm and the DIF structure conform to the DV data structure as defined in IEC 61834. The differences between the DV-based data structure defined in this standard and IEC 61834 are shown in annex A.
