  4. 3. On distributed real-time systems : the mStar environment, net-based learning and context-aware applications

    Författare :Kåre Synnes; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

    Sammanfattning : This doctoral thesis presents two frameworks for distributed real-time systems, the mStar environment for Computer Supported Collaborative Work (CSCW) and the Alipes architecture for context-aware applications, from the perspective of distributed teamwork and net-based learning. The mStar environment was designed to be symmetric and fully distributed, which allows all users equal access and thus full interactivity, as well as scalable through the use of IP multicast and a server-less design.

  5. 4. Towards Optimal Quality of Experience via Scalable Video Coding

    Författare :Pengpeng Ni; Damir Isovic; Mats Björkman; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quality-of-Experience; advanced video coding; MPEG-4; H264 AVC; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : To provide universal multimedia experience, multimedia streaming services need to transparently handle the variation and heterogeneity in operating environment. From the standpoint of streaming application, video adaptation techniques are intended to cope with the environmental variations by utilizing manipulations of the video content itself. LÄS MER
