These standards made interactive video on CD-ROM and Digital Television possible. MPEG-4 is the result of another international effort involving hundreds of researchers and engineers from all over the world. MPEG-4, whose formal ISO/IEC designation is ISO/IEC 14496, was finalized in October 1998 and became an International Standard in the first months of 1999. The fully backward compatible extensions under the title of MPEG-4 Version 2 were frozen at the end of 1999, to acquire the formal International Standard Status early 2000. Some work, on extensions in specific domains, is still in progress. MPEG-4 builds on the proven success of three fields: • Digital television; • Interactive graphics applications (synthetic content) ; • Interactive multimedia (World Wide Web, distribution of and access to content) MPEG-4 provides the standardized technological elements enabling the integration of the production, distribution and content access paradigms of the three fields. More information about MPEG-4 can be found at MPEG’s home page (case sensitive): http://www.cselt.it/mpeg . This web page contains links to a wealth of information about MPEG, including much about MPEG-4, many publicly available documents, several lists of ‘Frequently Asked Questions’ and links to other MPEG-4 web pages.

  • Structural Analysis of Low Latency Audio Coding Schemes
    Structural analysis of low latency audio coding schemes Manfred Lutzky, Markus Schnell, Markus Schmidt and Ralf Geiger Fraunhofer Institute for Integrated Circuits IIS, Am Wolfsmantel 33, 91058 Erlangen, Germany Correspondence should be addressed to: [email protected] ABSTRACT Low latency audio coding gains increasing importance among upcoming high quality communication applications like video conferencing and VoIP. This paper provides a comparison of two low latency audio codecs suitable for these tasks: MPEG-4 ER AAC-LD and ITU-T G.722.1 Annex C. Despite their similar coding strategies, both codecs show significant differences with respect to used tools and coding performance. A comparison of the coding tools is provided and the influence on different signal classes is discussed. Highly sophisticated audio codecs are necessary for 1.

  • Video Encoding with Open Source Tools
    Video Encoding with Open Source Tools Steffen Bauer, 26/1/2010 LUG Linux User Group Frankfurt am Main Overview Basic concepts of video compression Video formats and codecs How to do it with Open Source and Linux 1. Basic concepts of video compression Characteristics of video streams Framerate Number of still pictures per unit of time of video; up to 120 frames/s for professional equipment. PAL video specifies 25 frames/s. Interlacing / Progressive Video Interlaced: Lines of one frame are drawn alternatively in two half-frames Progressive: All lines of one frame are drawn in sequence Resolution Size of a video image (measured in pixels for digital video) 768/720×576 for PAL resolution Up to 1920×1080p for HDTV resolution Aspect Ratio Dimensions of the video screen; ratio between width and height. Pixels used in digital video can have non-square aspect ratios! Usual ratios are 4:3 (traditional TV) and 16:9 (anamorphic widescreen) Why video encoding? Example: 52 seconds of DVD PAL movie (16:9, 720x576p, 25 fps, progressive scan) Compression Video codec Raw Size factor Comment 1300 single frames, MotionTarga, Raw frames 1.1 GB - uncompressed HUFFYUV 459 MB 2.2 / 55% Lossless compression MJPEG 60 MB 20 / 95% Motion JPEG; lossy; intraframe only lavc MPEG-2 24 MB 50 / 98% Standard DVD quality X.264 MPEG-4 5.3 MB 200 / 99.5% High efficient video codec AVC Basic principles of multimedia encoding Video compression Lossy compression Lossless (irreversible; (reversible; using shortcomings statistical encoding) in human perception) Intraframe encoding
