New Report Examines Open and Proprietary Standards Including MP3, MPEG-2, MPEG-4, H.264 Advanced Video Coding, Real Networks, Windows Media and Quicktime.DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c47853) has announced the addition of 2006 Digital Media Technology - Digital TV, Mobile TV, IPTV, MPEG Report to their offering. Trends and frequencies As a prelude to detailed discussion of the various digital broadcasting technologies, we review the propagation of radio waves, the established analogue broadcasting techniques and the resulting spectrum management arrangements in which digital broadcasting takes place. We summarise the key technical and commercial trends and principles we believe characterise the digitisation of broadcasting. DVB and ISD B The distinctions between digital broadcasting for stationary video receivers, for mobile receivers and for small handheld devices. DVB standards which are used in most countries for digital video broadcasting. The report also discuss the Japanese ARIB ARIB - Association of Radio Industries and Businesses ISDB ISDB - Idaho School for the Deaf and the Blind ISDB - Industry Studies Data Base (EPA) ISDB - Integrated Satellite Data Base ISDB - Integrated Services Digital Broadcasting (Japan) ISDB - International Sectoral Data Base (OECD) ISDB - International Society of Drug Bulletins ISDB - Interoperability Standards Database digital standards, which are similar in principle to DVB-T. ATSC and Middleware The North American ATSC digital television broadcasting standard differs greatly from the DVB and ISDB techniques used in other countries. Technologies are looked at which affect broadcast television quality and usage, including real-time vs. offline compression and personal video recorders. The report also discusses the MHEG MHEG - Multimedia and Hypermedia information coding Expert Group and MHP middleware and transmission standards for digital television receivers. Sound and narrowband Three types of digital broadcasting for sound and data applications are discussed. Firstly, the low data rate systems RDS and DirectBand. Then we explain the capabilities and limitations of Digital Radio Mondaile and the two USA-based In Band On Channel HD Radio In-Band On-Channel (IBOC) HD Radio transmits the digital channels in unused portions of the same AM and FM channel. Because the IBOC method uses the same channels, radio stations can add the digital technology with relative ease. In comparison, deploying digital TV (DTV) is a far more costly and time-consuming venture. History iBiquity was formed in 2000 as a merger of Lucent spinoff Lucent Digital Radio and USA Digital Radio. systems. Finally we discuss the major wideband audio broadcasting system Eureka 147 and the satellite systems of WorldSpace, Sirius and XM. Mobile TV Broadcasting real-time and stored for replay sound, video and multimedia material to small handheld devices such as cellphones is the "Holy Grail" of both the telecommunications and broadcasting industries. We discuss the needs of such systems and the major approaches to achieving it: Eureka 147 T-DMB, DVB-H, ISDB-Tsb and Qualcomm's promising MediaFlo. We also discuss the Japanese and South Korean MBSAT 'T-DMB' broadcast system. Streaming media and conferencing The report examines open and proprietary standards including MP3, MPEG-2, MPEG-4, H.264 Advanced Video Coding, Real Networks, Windows Media and Quicktime. Bandwidth restrictions of last-mile technologies such as HFC and ADSL are discussed as well as the advantages and disadvantages of file vs. server streaming for multimedia serving. Video on demand The technical principles behind VoD are described, with special reference to IP multicasting, the need for extensive systems integration for all network elements, and the suitability for VoD and 'triple play' of the various access technologies: FttH, FttC, HFC, ADSL and WiMAX. AAC and Video The report discusses Advanced Audio Coding (audio) Advanced Audio Coding - (AAC) A successor to MP3, allowing lower bit rates and more stable quality. See MPEG-2 AAC Low Profile and MPEG-4 AAC Main Profile. (AAC) and how it improves on MP3. We explain enhancements to both AAC including Spectral Band Replication (SBR), Parametric Stereo and Scalable Lossless Coding. We discuss HILN HILN - Harmonic and Individual Lines plus Noise (algorithm) parametric audio coding and voice compression algorithms including CELP CELP - Cache-Enhanced Low-Profile (socket) CELP - Catalina Environmental Leadership Program CELP - Civilian Employment Level Program CELP - Code Excited Linear Prediction CELP - COMSOC Experts Lecturer Program (IEEE Communications Society). We also explain the process of MPEG-2 video compression, which is the basis of almost all digital television systems. Video and VRML Advanced Video Coding (AVC/H.264) improves on MPEG-2 video compression. The MPEG-4 standards are of unprecedented scope, including animation, synthetic sound and video, VRML interactivity and Java. We introduce these technologies and discuss how they can be used together to provide services and communication systems far beyond the modes we are familiar with today. We also discuss the MPEG-7 metadata and MPEG-21 digital rights management standards. MPEG1 and MP3 The report discussed MPEG-1 and MPEG-2 audio compression (coding) and major non-MPEG audio coding systems including Real Audio, Windows Media and Vorbis. A detailed explanation of the internal mechanism of MP3 (MPEG-1 Audio Layer III) compression serves as a basis for understanding MP3pro Spectral Band Replication (SBR) SBR encodes the high frequencies and stores them in the auxiliary data fields. The decoder restores the high frequencies from the SBR data. and all other perceptual audio codecs, including AAC.
