  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. 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.

  4. 3. Streaming Video over Unreliable and Bandwidth Limited Networks

    Författare :Hussein Aziz; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streaming video; Mobile device; Frame splitting; Sub-frame crossing; Time Interleaving Robust Streaming; Region of Interest; Mean Opinion Score;

    Sammanfattning : The main objective of this thesis is to provide a smooth video playout on the mobile device over wireless networks. The parameters that specify the wireless channel include: bandwidth variation, frame losses, and outage time. LÄS MER

  5. 4. Video Signal Processing: Compression Segmentation and Tracking

    Författare :Andrew Backhouse; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis considers three separate research problems within the field of video processing.The first is concerned with segmenting an image, the second with tracking an object and the third with the communication of video across an unreliable network.Segmentation is an application-specific problem.

  7. 5. Distribution and Individual Watermarking of Streamed Content for Copy Protection

    Författare :Karl-Göran Stenborg; Robert Forchheimer; Peter Parnes; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Watermarking; Fingerprinting; Video distribution; Broadcast; Multicast; Telecommunication; Telekommunikation;

    Sammanfattning : Media such as movies and images are nowadays produced and distributed digitally. It is usually simple to make copies of digital content. Consequently illegal pirate copies can be duplicated and distributed in large quantities. One way to deter authorized content receivers from illegally redistributing the media is watermarking. LÄS MER
