ABSTRACT
The Scalable Video Coding (SVC) extension to the H.264/AVC
video coding standard introduces multiple functionalities to the
H.264/AVC decoding process. These functionalities include
spatial, quality and temporal scalability. In this document, we
introduce an additional capability that is supported by the SVC
extensions. This feature is commonly referred to as bit-stream
rewriting, and it allows a multiple layer, scalable bit-stream to
be converted to a single layer, H.264/AVC compliant bit-steam
without loss and without reconstruction of image intensity data.
