ITU-T SG16 has begun a project to develop a “Media Coding Summary Database”, which is intended to summarize the key parameters of audio, video, graphic, still-image, and character coding standards around the world. We are interested in media codecs available for general use, from whatever source. This work is taking place within Q.E of SG16.
SG16 requests your help in populating this database, especially with regard to coding standards under your responsibility, both approved and works-in-progress.
The purpose of this database is to identify areas of where additional work may be needed and areas where coordination, cross-referencing, or harmonization may be desirable. A secondary goal is to issue a brochure, web page, or other publication summarizing the available media codecs and their main parameters. SG16 has so far made no decisions regarding which types of information will be published, and at what level of detail.
The spreadsheet accompanying this liaison contains our initial skeleton for the database. In some areas data has been filled in for media codecs under the responsibility of SG16, and in a very few cases for well-known media codecs from other standardization development organizations (SDOs). These data represent the information available at this meeting of SG16, and are not to be taken as reviewed or verified as correct. They are present primarily to offer examples of how the fields in the database are intended to be filled out.
For these reasons we request that you do not distribute this skeleton publicly at this time; however it is our expectation that the completed database will be made available to SDOs for their own use, provided ITU-T is credited as the source.
SG16 requests your input by return liaison. Specifically,
