Standards and domain ontologies are very important for providing semantic interoperability and information access in open environments. The MPEG-7 and MPEG-21 are the dominant efforts for the description of multimedia content and multimedia content services. The MPEG-7 Semantic DS has been shown to have powerful semantic description capabilities, which can utilize complex concepts, relationship...

The H.264 video compression standard provides tools for coding improvements of at least 2 dB, in terms of PSNR, and at least 50% in bit rate savings as compared with MPEG-2 video compression standard. It is expected that the H.264/MPEG-4 AVC will take over the digital video market, replacing the use of MPEG-2 in most digital video applications. The complete migration to the new video-coding alg...

Depth-Image-Based Rendering (DIBR) can synthesize a virtual view image from set of multiview images and corresponding depth maps. However, this requires an accurate map estimation that incurs high compu- tational cost over several minutes per frame in DERS (MPEG-I’s Depth Estimation Reference Software) even by using high-class computer. LiDAR cameras thus be alternative solution to real-time DI...

ATM network is a flexible environment to provide efficient transport of multimedia traffic. MPEG-encoded video information constitutes significant amount of transmitted data in broadband network. The paper investigates a gain which can be obtained when using results of statistical studies on stored MPEG files. Performance of transfer of MPEG information via CBR and rt-VBR links is studied.
