Abstract

Intra-codec scalability in the KOZ audio compression technology is presented in detail. The KOZ codec uses a psychoacoustic model and high-resolution spectral analysis to create, prioritize and layer audio objects, making it inherently scalable by varying the number of layers. The layers are sufficiently fine-grained to allow both smallstep and large-step bitrate variations in a light-weight, real-time process during content delivery. Decoder scalability based on availability of device resources is introduced. An overview of the architecture of the KOZ technology and some of the applications of its scalability are discussed.
