  5. 4. Preferential Coding for Mobile Multimedia Services

    Författare :Muhammad Imran Iqbal; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Different parts of source encoded multimedia streams such as those associated with standard image or video formats possess different levels of importance with respect to their contribution to the quality of the reconstructed image or video. This unequal importance among data within a codestream gives rise to preferential treatment of the more significant parts of the codestream compared to the less important parts. LÄS MER

  7. 5. Football on mobile phones : algorithms, architectures and quality of experience in streaming video
