active, Most Current
Organization: ETSI
Publication Date: 1 February 2018
Status: active
Page Count: 293
scope:

The present document specifies a coded presentation of audio information and specifies the decoding process. The coded presentation specified herein is suitable for use in digital audio transmission and storage applications. The coded presentation may convey full bandwidth audio signals, along with a low-frequency enhancement signal, for multichannel playback. Additional presentations can be included, e.g. targeting listeners with visual or hearing disabilities. A wide range of encoded bit rates is supported by decoders implemented according to the present document, ranging from state-of-the-art compression to perceptually lossless rates. The coded presentation is designed with system features such as robust operation, video frame synchronicity, and seamless switching of presentations.
