              RTP Payload Format for VC-2 HQ Profile Video
                    draft-ietf-payload-rtp-vc2hq-06

Abstract

   This memo describes an RTP Payload format for the High Quality (HQ)
   profile of Society of Motion Picture and Television Engineers
   Standard ST 2042-1 known as VC-2.  This document describes the
   transport of HQ Profile VC-2 in RTP packets and has applications for
   low-complexity, high-bandwidth streaming of both lossless and lossy
   compressed video.

   The HQ profile of VC-2 is intended for low latency video compression
   (with latency potentially on the order of lines of video) at high
   data rates (with compression ratios on the order of 2:1 or 4:1).

1.  Introduction

   This memo specifies an RTP payload format for the video coding
   standard Society of Motion Picture and Television Engineers ST
   2042-1:2017 [VC2] also known as VC-2

   The VC-2 codec is a wavelet-based codec intended primarily for
   professional video use with high bit-rates and only low levels of
   compression.  It has been designed to be low-complexity, and
   potentially have a very low latency through both encoder and decoder:
   with some choices of parameters this latency may be as low as a few
   lines of video.

   The low level of complexity in the VC-2 codec allows for this low
   latency operation but also means that it lacks many of the more
   powerful compression techniques used in other codecs.  As such it is
   suitable for low compression ratios that produce coded data rates
