Abstract:
Scalability is becoming an important characteristic for audio coding, particularly with the increasing variety of audio coding applications and equipment. The concept that more unified approaches to audio coding can elegantly scale and adapt across a wide range of deployment scenarios, while still delivering good levels of coding performance, is very appealing. Scalable audio coding is often considered in the context of scaling the coded bit-rate, but many other important forms of coding scalability exist. A panel of experts will discuss coding scalability across various characteristics, including coded bit-rate, computational complexity, robustness, and type of audio content. Consideration will be given to the challenges that real-world applications present for scalable audio coding and how future coding techniques might evolve to promote higher levels of scalability.
