MPEG-B Part 1 “Binary MPEG format for XML” (BiM) was originally developed a the technology to compress MPEG-7 Descriptors and Description Schemes and placed in MPEG-7 Part 1. BiM was then made a generic technology and moved to MPEG-B part 1. It provides a standard set of generic technologies to…
Generic MPEG Video Standards
MPEG-C Part 1 “Accuracy specification for implementation of integer-output IDCT” specifies the IDCT accuracy that is equivalent to or extends the IEEE 1180 standard. This standard referenced by quite a few image and video compression standards had been withdrawn and MPEG needed to restore the reference. Part 2 “Fixed-point 8×8…
Generic MPEG Audio Standards
MPEG-D Part 1 “MPEG Surround” provides an efficient bridge between stereo and multichannel presentations in low-bitrate applications. The MPEG Surround technology supports very efficient parametric coding of multi-channel audio signals, so as to permit transmission of such signals over channels that typically support only transmission of stereo (or even mono)…
Reconfigurable Media Coding
While MPEG was busily developing more and more video compression standards, China decided that it could well afford to have its own national digital audio-video-system technology and in June 2002 established the Audio and Video Coding Standard Workgroup of China (AVS). The group achieved its goal and in December 2003…
MPEG-4 Inside – Graphics
At the Tokyo meeting in July 1995 Hiroshi Yasuda showed up and proposed to address the coding of information that is partly natutal (e.g. a video, a music) and partly synthetic (e.g. 2D and 3D graphics). Work started in earnest, first as part of the AOE group and then, after…
Interaction Between Real And Virtual Worlds
Digital Media started with the digitisation of audio, video and images. But Digital Media is not confined to audio, video and images. So the MPEG-4 mission has been about implementing a plan to add more and more media types: composition, characters and font information, 3D Graphics etc. Other standards, like…
Technologies To Interact With Digital Media
The user interface is a very important component of Digital Media devices, services and applications. The sleek user interface offered by Apple products is quoted as a key element for their success. Recently user interfaces have evolved in two main directions: inclusion of more media types such as audio, video,…
Augmented Reality Application Format
Starting from Video, MPEG has gradually covered most of the media and related spectrum: Video Audio Systems technologies holding the two together, the interfaces with transport and, in the case of MPEG-2, the transport itself 3D scenes creation with such “objects” as 2D and 3D graphics, synthetic audio and their…
Inside Digital Media Devices
In its quest to provide the necessary standards for the Digital Media industry, MPEG started the MPEG Multimedia Middleware (M3W), a complete set of standards defining the software environment of a multimedia device. When responses to the M3W CfP were received MPEG selected the proposal coming from the Universal Home…
Getting Things Done My Way
Six months after leaving my employer of 32.5 years, I became CEO of CEDEO, an Italian company I had already a participation in, and made it the vehicle of my forays into the new business of technology use. Today the mission of CEDEO is To conceive, design, implement, deploy and…
