Foreword
SMPTE (the Society of Motion Picture and Television Engineers) is an internationally recognized standards
developing organization. Headquartered and incorporated in the United States of America, SMPTE has
members in over 80 countries on six continents. SMPTE’s Engineering Documents, including Standards,
Recommended Practices and Engineering Guidelines, are prepared by SMPTE’s Technology Committees.
Participation in these Committees is open to all with a bona fide interest in their work. SMPTE cooperates
closely with other standards-developing organizations, including ISO, IEC and ITU.
SMPTE Engineering Documents are drafted in accordance with the rules given in Part XIII of its
Administrative practices.
SMPTE Standard 425M was prepared by Technology Committee N26.
Introduction
SMPTE 292M was originally developed to provide a serial digital connection between HDTV equipment
operating largely with 10-bit Y’/C’

R
4:2:2 signals to a maximum frame rate of 30 frames per second. Over
time, SMPTE 292M applications were expanded to include larger picture formats, higher refresh rates and to
provide support for R’G’B’ and 12-bit source signal formats and the carriage of packetized data.
The total data rate required to support these additional applications is 2.970 Gb/s or 2.970/1.001Gb/s and the
digital interface used to carry these payloads is currently realized using a dual-link structure as defined in
SMPTE 372M.
This standard defines the mapping of various source image formats onto a single link serial digital interface
operating at a nominal rate of 3Gb/s, offering an alternate method to SMPTE 372M for the transport of signals
with a total payload of 2.970 Gb/s or 2.970/1.001 Gb/s.
