Amendment 3 to Rec. ITU-T T.800 | ISO/IEC 15444-1 specifies profiles for video broadcast applications. These profiles enable use of the wavelet-based JPEG 2000 codec for the coding and display of timed sequences of images. Such sequences of images are referred to as video. In changes to Annex A, the profiles and levels for video broadcast applications are defined and the associated constraints are specified. A new Annex M is added to specify an elementary stream format for carriage of JPEG 2000 encoded video for broadcast applications.

This amendment was developed as common text in collaboration with ISO/IEC JTC 1/SC 29/‌WG 1. As of the approval of this amendment, ISO/IEC JTC 1/SC 29 was also preparing Rec. ITU-T T.800 (2002) | ISO/IEC 15444-1:2004 Amd.3, which had not progressed to FDAM stage; therefore, it could not yet be considered for approval by ITU. Since this amendment on "Profiles for broadcast applications" to Rec. ITU-T T.800 | ISO/IEC 15444-1 was balloted by ISO/IEC JTC 1/SC 29 as PDAM 4, FPDAM 4, FDAM 4, it was kept as for the ITU-T approval process purposes also numbered as Amendment 4, even though Amendment 3 was neither approved or yet available for consideration under AAP. After approval, in order to keep the temporal numbering approach of the approved Recommendations | International Standards, this amendment was renumbered as Amendment 3 for publication purposes.
