This paper presents an overview of the video compression standards related to the MPEG family. MPEG-7 and MPEG-21 are specially covered including its latest standard. MPEG-7 is mainly used for object descriptions and MPEG-21 is for DRM (Digital Rights Management). Keyword: MPEG-1, MPEG-2, MPEG-4, MPEG-7, MPEG-21, MPEG-A, MPEG-D I.INTRODUCTION MPEG is the “Moving Picture Experts Group”, working under the joint direction of the international Standards Organization (ISO) and the International Electro Technical Commission (IEC). This paper will provide an overview of the recent standards in the MPEG family. MPEG-7 is developed for Multimedia content description interface ,it uses XML to store metadata, and can be attached to timecode in order to tag particular events, or synchronise lyrics to a song. MPEG-21 is an open framework for multimedia delivery and consumption. It can be used to combine video, audio, text and graphics. The other latest version in MPEG like MPEG-A, MPEG-D is also...

The digital versatile disc (DVD) is a new optical recording medium with a storage capacity seven times higher than the conventional compact disc (CD). The major part of the capacity increase is achieved by the use of optics, shorter laser wavelength, and larger numerical aperture, which reduces the spot diameter by a factor of 1.65. The track formed by the recorded pits and lands, as well as the track pitch, can be reduced by the same factor. The storage capacity is further increased by a complete redesign of the logical format of the disc, including a more poweiful error correction and recording code. The system requirements of the DVD and the related channel coding are outlined in this paper.

ABSTRACT We describe a system for storing, transmitting and presenting digital films in a computer network. The hardware used in the system is standard hardware, as found in typical workstations today; no special hardware is required. The movies are shown in a window of the X Window System. This allows full integration with the classical components of computer applications such as text, color graphics, menues and icons. The X-MOVIE system is based on color lookup table technology. We present a new algorithm for the gradual adaptation of the color lookup table during the presentation of the film.

Digital television is a reality today, but multimedia communications, after years of hype, is still a catchword. Lack of suitable multi-industry standards supporting it is one reason for the unfulfilled promise. The MPEG committee which originated the MPEG-1 and MPEG-2 standards that made digital television possible is currently developing MPEG-4 with wide industry participation. This paper describes how the MPEG-4 standard, with its networkindependent nature and application-level features, is poised to become the enabling technology for multimedia communications and will therefore contribute to solve the problems that are hindering multimedia communications.

Interactive video has seemed to have significant promise for improving learning in schools since the 1970s but never reached its maximum potential in foreign language instruction. Digital Versatile Disc (DVD) now appears poised to make this potential a reality. After a relatively difficult beginning, DVD videos are being made increasingly available as major producers are starting to commit to this new format. After reviewing technical and legal issues surrounding the use of DVD, the writer describes authoring possibilities that, although initially complex, can simplify the ultimate delivery of interactive video materials to language learners. Finally, he concludes the article by detailing the process of creating a DVD

This paper provides a technical overview of MPEG++, a robust video compression and transport system for digital HDTV. MPEG++ forms the basis of 'Advanced Digital Television' (ADTV), the all-digital terrestrial simulcast system currently under development by the Advanced Television Research Consortium (ATRC). ADTV incorporates an efficient MPEG-compatible compression algorithm at its central core, with application-specific data prioritization and transport features added as separable layers. The compression process is based on a 1440x960 (1050-line 2:1 interlaced) HDTV format, producing a selectable bit-rate in the region of 15 20 Mbit/s. The data priorization layer of MPEG++ achieves robust delivery over an appropriate two-tier modem by separating compressed video data into high-and standard-priority bitstreams with appropriate bit-rates. This priorized data is then formatted into fixed length 'cells' (packets) with appropriate data-link level and service-specific adaptation level headers, designed to provide capabilities such as flexible service multiplexing, priority handling, efficient cell packing, error detection and graceful recovery from errors. An outline of each of the above MPEG++ elements (i.e., compression, prioritization and transport) is given, and is followed by a description of a software model for the system. Simulation model based performance results which illustrate MPEG++ image quality and robustness are briefly reported.

With the rapid convergence in telecommunications, computer, and TVIfilm industries, rigorous efforts are in progress for designing the emerging multimedia standard-MPEG-4. The main features of MPEG-4 z e its content-based interactiviry, ejjicient coding, and universal access. For realizing MPEG-4 based application oriented systems, various issues must be carefully addressed. This paper describes a full scale MPEG-4 based interactive multimedia system project underway at the Video Technology Center of the Hong Kong University of Science and Technology. This project aims to provide complete MPEG-4 based interactive services tailored to various applications. In order to do so, a number of key enabling technologies need to be investigated. These include encoding and decoding, multimedia server design, auser interface, and MPEG-4 stream transmission over high speed networks. The unique features ofthe project are: 1) to explore the feasibility of parallel and distributed technology using Network-of-Workstations (NOWs) to hinder thc intensive computation required for realtime encoding; 2) to provide flexibility of software-based encoding/decoding; 3) to design an intelligent transport service mechanism which can satisfy QoS requirement of MPEG-4.

With the development of the MPEG-4 standard in 1998, a new way of creating and interacting with audio-visual media was conceived. This chapter provides an overview of this new standard. Topics covered in the chapter include a description of visual and audio objects, both natural and computer generated, and a description of how scenes are put together in MPEG-4. We also present an overview of the systems necessary for MPEG-4 operation and insight into possible Internet-based multimedia applications. We briefly discuss some research issues in MPEG-2 design and implementations. Interactive multimedia, storage and retrieval of VCR quality video on CD-ROM. Digital TV, HDTV, broadcasting satellite services, electronic cinema, home television theatre. Interactive multimedia, mobile multimedia, content-based storage and retrieval, video games, video broadcast, collaborative scene visualization.
