Abstract

This memo specifies a packetization scheme for encapsulating uncompressed video into a payload format for the Real-time Transport Protocol, RTP. It supports a range of standard- and high-definition video formats, including common television formats such as ITU BT.601, and standards from the Society of Motion Picture and Television Engineers (SMPTE), such as SMPTE 274M and SMPTE 296M. The format is designed to be applicable and extensible to new video formats as they are developed.

Abstract

   This memo specifies a packetization scheme for encapsulating
   uncompressed video into a payload format for the Real-time Transport
   Protocol, RTP.  It supports a range of standard- and high-definition

1.  Introduction

   This memo defines a scheme to packetize uncompressed, studio-quality
   video streams for transport using RTP [RTP].  It supports a range of
   standard and high-definition video formats, including ITU-R BT.601
   [601], SMPTE 274M [274] and SMPTE 296M [296].

   Formats for uncompressed standard definition television are defined
   by ITU Recommendation BT.601 [601] along with bit-serial and parallel
   interfaces in Recommendation BT.656 [656].  These formats allow both
   625-line and 525-line operation, with 720 samples per digital active
   line, 4:2:2 color sub-sampling, and 8- or 10-bit digital
   representation.

   The representation of uncompressed high-definition television is
   specified in SMPTE standards 274M [274] and 296M [296].  SMPTE 274M
   defines a family of scanning systems with an image format of
   1920x1080 pixels with progressive and interlaced scanning, while
   SMPTE 296M defines systems with an image size of 1280x720 pixels and
   progressive scanning.  In progressive scanning, scan lines are
   displayed in sequence from top to bottom of a full frame.  In
