MPEG-4 Video standards specify new technologies

 

Redmond, WA(US), 27 July 2004

The Joint Video Team (JVT) has completed its extension of AVC/H.264. Fidelity Range Extension (FRExt), as it called, includes four new profiles that broaden an already wide ranging set of applications that are well suited to AVC/H.264. The new profiles are fully nested beginning with “high” profile (HP) for high definition content. Hi10P incorporates 10 bit coding suitable for film material. Hi422 provides the video community with the capabilities needed in broadcasting and editing. Lastly, Hi444 supports full RGB color resolution and 12 bit precision for professional production and graphics environments. Demanding video production environments are further supported with the ability of carry compressed alpha channel data and the film industry now has the ability to analyze and synthesize the representation of film grain for high quality consumer applications.

The MPEG-4 visual standard completed almost 5 years ago continues to be improved with the addition of two levels to Simple Profile. Level 4a, as it being called, documents VGA resolution in wide use throughout the PC industry today.  Level 5 extends Simple Profile to SD (standard definition) TV resolutions.

In other MPEG News

In response to industry demand for a light weight scene representation that is also compatible with existing technology, MPEG has produced version 1 of LASeR (Lightweight Application Scene Representation). LASeR can be implemented in as few as 30Kilobytes and leverages the functionality of industry standards such as MPEG-4 BIFS, W3C SVG and Macromedia Flash. A fully compatible W3C SVG T1.2  LASeR compressed SVG stream can deliver rich graphic content in as little as 10kbps.

Details of how to obtain MPEG’s Calls for Proposal’s (CfPs) and other public information is shown below.

 

Call for Proposals on MPEG-A Symbolic Music Representation

 MPEG is seeking technology responses that propose solutions for the specification of Symbolic Music Representation format. Symbolic Music Representation is capable of coding symbolic representations of music in a manner that allows its integration into other parts MPEG-4. MPEG-4 permits the encoding of multimedia content, including many different kinds of object types and a scene description allowing precise synchronization among them and specifying object composition rules. This Call is for MPEG-compatible technology to support symbolic representations of music (Symbolic Music Representation) synchronized with other MPEG object types. Proponents are requested to include demonstrator tools able to give evidence of the functionalities they are proposing.

 

Future MPEG meetings are as follows: 70^th meeting in Palma de Mallorca October 18-22, 2004, and the 71^st in Hong Kong, China January 17-21, 2005 and the 72^nd meeting in the Republic of South Korea April 18-22, 2005
