Abstract:


    With the introduction of H.264, the complexity on video encoders has increased dramatically. As hardware based encoding solutions profit from the strict sequential design and already feature real time capabilities for high definition material, software solutions lack most of the encoding performance. More precisely, the performance of software encoders is limited due to the computation power of encoding system as well as the high level of codec-intern dependencies. As a consequence, software encoders supporting high definition needs are very rare.
