Adaptive bit-rate audio will be rationalized into a single efficient encode.
DTS has introduced its adaptive solution to the varied needs of media streaming. DTS-HD Layered Audio has several goals, but namely the idea is to deliver the best quality audio to consumers whenever they are streaming video. How DTS plans to accomplish this is in a design that streamlines the effort and space required by streamer's host and video encoder.
As with other DTS designs, DTS-HD Layered Audio contains down step streams, which allow for one single encode to handle a variety of bandwidth and hardware configurations from the best available on the high end to the only realizable on the low end.
Along with streamlining the encoding process and resulting single container of multiple adaptive bit-rate audio streams, DTS has also applied binary compression techniques learned from development of lossless standards like DTS-HD MA in order to keep the footprint of a DTS-HD Layered Audio encode to a minimum.
"Benefits of DTS-HD Layered Audio include:
Enables adaptive bit-rate audio streaming at almost no additional cost from a single encode
Ideal for live streaming, eliminating the need to time align multiple encodes of the same track at various bit-rates
Smaller storage footprint compared to traditional adaptive bit-rate audio solutions"
