Technical Summary This memo describes an RTP payload format for the ISO/IEC International Standard 15444-1 | ITU-T Rec. T.800, otherwise better known as: JPEG 2000. JPEG 2000 features are considered in the design of this payload format. JPEG 2000 is a truly scalable compression technology allowing applications to encode once and decode many different ways. JPEG 2000 video stream is formed by extending from a single image to a series of JPEG 2000 images. Working Group Summary This is a reasonably standard RTP payload format, although it has been under discussion since the 52nd IETF. Key discussion points in the working group were the provision of optional IPR-encumbered features (now removed to draft-ietf-avt-rtp-jpeg2000-beam-09.txt) and allowing the use of non-90kHz RTP timestamp rates, for high accuracy synchronisation when non-standard frame rates are used. Document Quality Media type review was conducted starting 24 September 2007, with no objections raised. There is at least one implementation. Personnel The document shepherd is Colin Perkins. The responsible area director is Cullen Jennings.
