Stream morphing is a new approach to scalable video coding similar in scope to those already included in the MPEG standards. It works by exploiting redundancy between a hierarchy of single layer bitstreams of increasing quality. This paper provides an overview of the technique along with results for the constant quantizer SNR scalable case which demonstrate good performance, especially for the class of "low motion" video sequences. In addition to SNR scalability, stream morphing has also been applied to temporal and spatial scalability.
