  1. 1. Supporting Video-mediated Communication over the Internet

    Författare :Mathias Johanson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; layered multicast; distributed collaborative work; layered video coding; robust video transmission; Internet video; video gateways; video-mediated communication; congestion control; teleconferencing; stereoscopic video;

    Sammanfattning : The tremendous success of the Internet in providing a global communication infrastructure for a wide variety of applications has inspired the invention of packet video systems for synchronous interpersonal communication. The potential benefits of video-mediated communication are numerous, ranging from improved social interactions between individuals to more efficient distributed collaborative work. LÄS MER

  3. 2. On Enhancement and Quality Assessment of Audio and Video in Communication Systems

    Författare :Andreas Rossholm; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QoE; video quality assessment; video quality metric; multi-linear regression; artificial neural network; support vector machine; quality predictor; machine learning; temporal scaling; spatial scaling; video compression; deblocking filter; noise cancelling; synchronization; audio delay; video delay; GSM interference signal; noise cancellation; notch filtering;

    Sammanfattning : The use of audio and video communication has increased exponentially over the last decade and has gone from speech over GSM to HD resolution video conference between continents on mobile devices. As the use becomes more widespread the interest in delivering high quality media increases even on devices with limited resources. LÄS MER

  4. 3. Internet Video Transmission

    Författare :György Dan; Gunnar Karlsson; Viktória Fodor; Jean-Yves Le Boudec; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic control; MDC; FEC; Multicast streaming; Queuing theory; Telecommunication; Telekommunikation;

    Sammanfattning : The Internet has rapidly evolved from being a scientific experiment to a commercial network connecting millions of hosts that carries traffic generated by a large amount of applications with diverse requirements. Its architecture was however designed to enable efficient point-to-point delivery of bulk data, and can not provide statistical guarantees on the timely delivery of delay sensitive data such as streaming and real-time multimedia.

  5. 4. P2P Live Video Streaming

    Författare :Ilias Chatzidrossos; Gunnar Karlsson; Marco Mellia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; p2p systems; live streaming; mesh-based systems; Telecommunication; Telekommunikation;

    Sammanfattning : The ever increasing demand for video content directed the focus of researchfrom traditional server-based schemes to peer-to-peer systems for videodelivery. In such systems, video data is delivered to the users by utilizing theresources of the users themselves, leading to a potentially scalable solution. LÄS MER

  7. 5. Traffic Control for VBR Video in Packet Switched Networks

    Författare :György Dán; KTH; []
    Nyckelord :Traffic control; VBR video; shaping; FEC; QoS;

    Sammanfattning : The best effort service offered by the Internet is notsatisfactory for the transmission of loss and delay sensitivedata, such as real-time voice and video. In order to provideservice guarantees at reasonably high load levels, additionalcontrol functions haveto be employed in the network. LÄS MER
