Abstract
H.264/SVC, the Scalable Video Coding extension of the H.264/AVC video coding standard, features spatial, quality and temporal scalability. Backwards compatibility with legacy decoding devices is maintained through an H.264/AVC compliant base layer, which represents the lowest quality of an H.264/SVC bit-stream. However, it is often desirable to also provide the higher quality layers to legacy H.264/AVC devices. This is achieved by a process commonly known as “bit-stream rewriting”, which allows for an efficient H.264/SVC to H.264/AVC conversion by exploiting the similarities of the two codecs. This paper describes a demonstrator showing the advantages of including an improved version of the bit-stream rewriting tool from the existing JSVM H.264/SVC reference software in an H.264/SVC-based multimedia delivery system, by integrating it into a Media Aware Network Element.
