1、 Copyright 2011 by THE SOCIETY OF MOTION PICTURE AND TELEVISION ENGINEERS 3 Barker Avenue., White Plains, NY 10601 (914) 761-1100 Approved March 30, 2011 Document Roadmap The SMPTE 292 suite of documents defines the mapping of various source image formats onto serial digital interfaces operating at
2、a nominal rate of 1.5 Gb/s. This informative “roadmap” describes the documents in the 292 suite. 1 SMPTE ST 292-1 SMPTE ST 292-1 defines a bit-serial data structure and the coaxial cable interface specifications for 1.5 Gb/s nominal Signal/Data Serial Interface to carry either 1280720, 19201080 or 2
3、0481080 active pixel formats mapped into the 1.5 Gb/s payload. This standard defines the method of serializing the parallel source format data to a serial bit stream. This interface may also carry packetized data mapped into the 1.5 Gb/s transport payload providing the constraints imposed by the ref
4、erence source image formats are observed. This standard specifies a coaxial cable interface suitable for application where the signal loss does not exceed an amount specified by the receiver manufacturer, typical loss amounts would be in the range of up to 20 dB at one-half the clock frequency.
