IEEE 1857.8-2020 PDF

This standard specifies the compression, decompression and packaging tools and mechanism which support the efficient transmission and storage of the multimedia data over internet and flexible configuration of compression parameters for providing better Quality of Experience (QoE) about bit rate and subjective assessment of playback quality, aiming at satisfying the requirement of network user, such as self-made multi-tracks and multi-components audio production, or audio scene coding. These include the bit rate from 16 kb/s/ch to 192 kb/s/ch and multiple channels up to 128 for audio signals with sampling frequency 8 kHz to 192 kHz and quantization resolution 8 bit, 16 bit, and 24 bit.
This standard is the second generation of IEEE Std 1857.2™-2013, which provides more flexible and high efficiency coding tool sets for compression, decompression, and packaging of the audio data, which should double the coding efficiency of IEEE Std 1857.2-2013. The target applications and services include, but are not limited to, the audio accompanying video and other audio services and applications, such as the audio accompanying Internet video, TV audio system, digital audio storage, audio broadcasting, and communication.
New IEEE Standard – Active. This standard is the second generation of IEEE Std 1857.2-2013, which provides more flexible and high efficiency coding tool sets for compression, decompression, and packaging of the audio data, which should double the coding efficiency of IEEE Std 1857.2-2013. The target applications and services include, but are not limited to, the audio accompanying video and other audio services and applications, such as the audio accompanying Internet video, TV audio system, digital audio storage, audio broadcasting and communication, virtual reality and panoramic audio, etc.
