SOS Interoperability Interoperability, Drivers and Inhibitors Bernard Barani Attaché - DG INFSO-D [email protected] ETSI Workshop “S.O.S Interoperability” Sophia Antipolis, 26 May 2005 NB: The views expressed herein are those of the authors and are not necessarily those of the European Commission Interoperability There is no “One Size fits all” definition for Interoperability Framework Directive, service focus; Software Directive, focus on portability of codes across various machines and environments; Copyright Directive; EICTA White Paper; DRM High Level Group ???? ⇒ Not a new notion, but rapidly evolving and acquiring new dimensions Interoperability What is changing Once, a notion for ICT industry experts, e.g ATM/MPEG/IP/DVB co- existence or compatibility. But: an exploding number of heterogeneous network infrastructures, context dependent (still); a plethora of (web) services, with multiple combination/bundling capabilities; a bombing of (networked) Consumer Electronic devices, with most of the functionalities unknown to the user; Threats and vulnerability of IP based systems, compared to former TDM based systems ⇒ With networked ICT becoming more and more pervasive, consumers are becoming intuitively aware of what “interoperability” means (e.g DVD regional codes, fairplay DRM on i_pod…). This may be the real change, i.e where the pressure on interoperable solutions may be expected Interoperability, multifaceted • At the Network/Device Level – Wireless/Mobile/Fixed/Cable/ISP/Broadcasting networks need to interoperate • At the Service/application Level – Services need to run across homogeneous or heterogeneous networks • At the Media/Content Level – Different media formats must coexist Interoperability is not an end in itself. It has to answer policy challenges: - Ensuring smooth technological transitions - Creating opportunities for disruption and innovation - Contributing to setting the right collaborative standards and widest market footprint - Optimising for innovation through accrued competition Interoperability & Home Networks Internet, Music and VoD, Video TV/video everywhere streaming, music download, storage Web Tablet Home Laptop Video walkman automation PDA and Control Bluetooth and Wi-Fi Phones Users want their devices to work together and share content Printer Media Centre Voice and video Telemedicine Game Console IP STB and PVR conferencing Telework Interoperability challenge in this context include notably: Consumer issues Home Gateway control Interoperability & Convergence Does convergence push the case for interoperability?? In principle Yes, but: In addition to the plethora of technologies, It introduces novel elements of complexity: m_payments, regulation on contents, rights holder… Untested and risky business models: more opportunities, but more risk; Different sectors (CE, mobile, broadband, broadcast..), with different logics: reducing customer churn and getting increased revenues; mastering content distribution; keeping control of established customer base; starting completely new « opportunity driven » businesses (e.g Skype) ⇒ For some players interoperability, insofar as it implies large scale convergence with significant levels of substitution, may mean risk of disappearing. Interoperability is it a natural trend? Still in the context of convergence: Untested business models, risks, requirement to protect investments may drive proprietary closed solutions, e.g music download fragmentation of devices and technologies; Some do however believe that market forces are enough to break the walls: "If you were to ask me which mobile device will take top place for listening to music, I'd bet on the mobile phone for sure. As good as Apple may be, I don't believe the success of the iPod is sustainable in the long run,“ (Bill Gates, to Frankfurter Allgemeine Zeitung) Some other believe that technology may be used as gatekeeper, no real incentive to move towards real interoperability and that legislative and regulatory intervention is needed (e.g case of Digital content portability and copy right) ⇒ But delicate issue to regulate on nascent markets; The Digital media formats maze Imaging Audio Video • BMP •PCT •a2b •MP4 •ASF •MPEG-1 •CLP•PCX • AAC • MPEG Audio • AVI •MPEG-2 •DCX•PNG •AC-3 •PCM •DAT•MPEG-4 • QuickTime •DIB• PPM • ADPCM •DivX • QuickTime • RealAudio •FPX•PSD •AIFF •DV•RM • PSP •TAC •GIF •ATRAC3+ •FLC•UIS •RAW • TwinVQ (VQF) •IMG •AU •FLI•WMV •RLE •u-law •JIF •CDDA Compression •FLX •TIFF •WAV •JPEG•WPG •DPCM •GIF •MAC •EPAC •WMA •MSP •MP3 Interoperability maze • Numerous competing technologies and alliances with assets and drawbacks • The home networking market is immature and fragmented Services Platforms (standards) Physical Layer (standards) OSA PhonePNA Web Services IEEE802.11 JINI HiperLAN OSGI Bluetooth MHP/DVB Home Plug Interconnect architecture (standards) Personalisation (standards) OSGi CC/PP JINI MPEG 7,21 UPnP Presence Interoperability Regulations and possible impacts (examples) e.g content download authorised on an national basis , as a function of the rights acquired with the local Collecting society. (IP address filtering). Putting restrictions to “fixed mobile convergence”, on the basis of national market organisations? regulation for Home Gateway interconnection or routing of regulated services provided though « foreign » IP platforms, example of DVB-H case, will probably depend from sectorial regulations. It is convergent, interoperable (mobile, broadcast). May depend from sectorial developed regulation: TV w/o frontiers, e commerce directive, regulatory package, copyright directive, …. ( broadcast? Mobile?) ⇒ regulation has a potentially high impact on how “interoperable systems” are deployed. Media and Home Delivery, finding the right equilibrium Consumers’ needs, wants, willingness to pay Interoperability depends critically on cross industry agreements and on associated regulation/contractual framework Technology Technology Media industry industry industry defining what defining what defining what is possible is possible is “allowed” Widespread Supply Side Enthusiasm for Interoperability Industry standard to reduce confusion/aid adoption Other 8% Non-interoperablity 4% will result in a market leading format via 13% competition/ choice Interoperability reduces consumer Not necessarily what confusion/aids consumer would say! adoption (No DRM?) 75% Question asked: Considering the compatibility of audio codecs and DRM technologies and their impact upon consumer adoption of digital music stores and services, please select from the following statements that which best describes your opinion Source: JupiterResearch Music Executive Survey 07/04 (Western Europe only) Interoperability & Standards There is a wide spread agreement that interoperability critically depends on standards.

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.

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
