ITU-T T Series Recommendations: New Documents

[ T.Sup2 (03/11) ] - ITU-T T.83x-series - Supplement on information technology - JPEG XR image coding system - System architecture

ven, 26 jan 2012 15:12:19 GMT

Summary

Supplement 2 to ITU-T T-series Recommendations is technically aligned with ISO/IEC TR 29199-1 but is not published as identical text. It was drafted in collaboration with ISO/IEC JTC 1/SC 29/WG 1 (which is informally known as "JPEG").

This Supplement provides a technical overview and informative guidelines for applications of the JPEG XR image coding system as normatively specified in Recommendation ITU-T T.832 | ISO/IEC 29199-2, Recommendation ITU-T T.833 | ISO/IEC 29199-3, Recommendation ITU-T T.834 | ISO/IEC 29199-4, and Recommendation ITU-T T.835 | ISO/IEC 29199-5. The overview of JPEG XR coding technology includes a description of the supported image formats, the internal data processing hierarchy and data structures, the image tiling design supporting hard and soft tiling of images, the lapped bi-orthogonal transform, supported quantization modes, adaptive coding and scanning of coefficients, entropy coding, and finally the codestream structure. This overview provides a basic understanding of how a JPEG XR encoder works and the various modes it supports. It also compares the JPEG XR design with those of baseline JPEG (Recommendation ITU-T T.81 | ISO/IEC 10918-1) and JPEG 2000 (Recommendation ITU-T T.800 | ISO/IEC 15444-1). Following the overview is a discussion of the use of JPEG XR for high dynamic range (HDR) image coding. Clause 8 reviews various JPEG XR profiles and describes their target applications. Clause 9, encoding practices, provides general encoding guidelines and guidelines for encoding for providing random access functionality, including an analysis of tile size selection trade-offs. A decoding process functionality, clause 10, describes the decoding process and output colour conversions, and describes how to make use of JPEG XR scalability features in a decoding application. These scalability features include resolution, quality and spatial random access scalabilities. Finally, clause 11 describes codestream manipulations in the compressed domain. This clause describes methods for trimming a codestream to extract a smaller codestream, switching between spatial and frequency codestream modes, rotation and flipping of images, extraction of a region of interest in the compressed domain, switching between interleaved and planar alpha planes, and modifying the tile structure of an image. This Supplement is intended to help application developers to understand the JPEG XR design and to provide assistance in making effective use of its capabilities.

[ T.88 (2000) Amendment 3 (05/11) ] - Extension to colour coding

ven, 26 jan 2012 15:08:54 GMT

Summary

Amendment 3 to Recommendation ITU-T T.88 | ISO/IEC 14492 is the first amendment to introduce colour extension into JBIG2. There are many ideas and possibilities to incorporate colour information on JBIG2. In this amendment, as the first step of introducing coloured information, the following principles are adopted.

In order to show the text region segment with colour support, a flag to show colour supporting the text region segment and a flag to show its colour space (e.g., sRGB) are defined. Colour information is attached to the end of the text region segment as colour section, and ITU-T T.45 representation is used to code colour change information to keep the decodability by the current decoder. A total of 32 colours are defined by default in this amendment. An additional colour dictionary can be defined using ITU-T T.45-like expression in the colour palette segment. In the generic region segment, if background colour is needed to be defined, another intermediate region segment which has the colour as foreground should be placed under the segment. The order of the priority in the layout is newly defined.

Summary

Recommendation ITU-T T.809 | ISO/IEC 15444-10 is a work item subdivision of ISO/IEC 15444 that provides extensions of Recommendation ITU‑T T.800 | ISO/IEC 15444-1 and Recommendation ITU-T T.801 | ISO/IEC 15444-2 for logically cuboidal data sets. In particular, it respects all existing capabilities and syntax of Recommendation ITU‑T T.800 | ISO/IEC 15444-1 and part of the existing capabilities of Recommendation ITU‑T T.801 | ISO/IEC 15444-2 for multi-component images, while providing alternatives and extensions to some of those capabilities. Within these constraints, it provides an isotropic specification for three-dimensional data sets, i.e., the project provides identical processing capabilities in all three dimensions even though Recommendation ITU‑T T.800 | ISO/IEC 15444-1 and Recommendation ITU-T T.801 | ISO/IEC 15444-2 codestream syntax differentiates between the two spatial axes and the cross-component axis. The context models currently used in this Recommendation | International Standard are as in Recommendation ITU-T T.800 | ISO/IEC 15444-1 and Recommendation ITU-T T.801 | ISO/IEC 15444-2. Improved context models will be introduced through an amendment.

Corrigendum 1 (05/2011, integrated in this new edition) corrects a number of minor mistakes that were present in various formulae of Annex B. It also provides a more formal and unambiguous description on the mandatory use of the CAP marker segment in the codestream, in order to enhance interoperability with the other parts of the JPEG 2000 standard. Furthermore, it introduces a new annex on how quantization should be handled for JP3D images.

[ T.833 (09/10) ] - Information technology - JPEG XR image coding system - Motion JPEG XR

sam, 08 jui 2011 15:34:35 GMT

Summary

Recommendation ITU-T T.833 is technically aligned with ISO/IEC 29199-3 but is not published as identical text. It was drafted in collaboration with ISO/IEC JTC 1/SC 29/WG 1 (which is informally known as "JPEG").

This Recommendation | International Standard is the Motion JPEG XR file format specification. The Motion JPEG XR file format is designed to contain one or more motion sequences of JPEG XR images, with their timing. The format is based on the ISO base media file format. It is intended as a 'building block', specifying only the video format. An application would be expected to combine Motion JPEG XR with suitable audio, metadata, etc., for a complete application specification; that specification would normally select profiles and levels of Motion JPEG XR, and could also specify application profiles and levels that apply to the integration.

Motion JPEG XR is expected to be used in a variety of applications, particularly where JPEG XR image coding technology is already available for other reasons, or where the high-quality frame-based approach, with no inter-frame coding, is appropriate.

Motion JPEG XR is a flexible format, permitting a wide variety of usages, such as editing, display interchange, and streaming.

Summary

This Amendment adds guidelines to ITU-T T.800 | ISO/IEC 15444-1 for the usage of JPEG 2000 in the framework of digital cinema applications.� Three topics are addressed in these guidelines.

The first is dedicated to reliable multicast transmission of JPEG 2000 codestreams because Digital Cinema content may be delivered to the theatres by using several communication channels, and many of them can be wireless, such as DVB-T, DVB-S, and WiMAX.

The second topic is related to implementation guidelines for Digital Cinema distribution. One of the guidelines provides quantization steps for 2K visually lossless compression based on perceptual thresholds. Also included are visual weightings for digital cinema conditions, which improve the quality of the JPEG 2000 DCinema profiles. The third topic gives practical rules for using JPEG 2000 in motion picture archives.

Summary

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.
