abstract

  • Fully configurable video coding is a novel approach to video compression in which a video decoder can be dynamically constructed based on a decoder description. This paper presents a new syntax for describing
    video decoder functionality and structure, namely, the decoder
    description syntax (DDS). The DDS is a platform-independent syntax that
    can define all aspects of a video decoder in terms of basic processing
    instructions. A DDS description of a video decoder may be coded and
    transmitted, and then executed by a generic processing platform, a
    "universal video decoder (UVD)." Any new or modified video decoding
    function may be described, communicated, and instantiated using the DDS,
    which makes it possible to rapidly implement new coding algorithms, to
    dynamically adapt the coding algorithm to suit the video data, and to
    efficiently implement multiple coding formats on one platform. We
    present examples of video decoding functions implemented in the DDS and
    show how these may be executed on a UVD. We demonstrate that flexible
    configuration, re-configuration, and decoding of video can be achieved
    using a real-time prototype UVD with functions transmitted and
    instantiated on-the-fly using the DDS.
