4 Overview p. 9
The speech and audio media capabilities defined in this specification are primarily introduced in order to be used as content format in the context of 5G Media Streaming, but not restricted to this use case. Parameters for audio encoder/decoder, content format and transport are defined.
The present document defines:
- Media decoding capabilities: the requirements for a receiver in terms of decoding
- Media encoding capabilities: the requirements for a sender in terms of encoding
-
Operation Points: A collection of discrete combinations of different content formats and the encoding formats. Operation Points are supported by
- Bitstream Requirements: A media bitstream that conforms to an audio or speech encoding format and certain Operation Point.
- Receiver Requirements: A function that can decode and playback any Bitstream that is conforming to a certain Operation Point in real-time.
- Sender Requirements: A function that can process and encode any Bitstream that is conforming to a certain Operation Point in real-time.
- The integration of each Operation Point in 5G Media Streaming as defined in TS 26.501 and TS 26.511.

5.1 Introduction p. 10
This clause documents speech and audio media capabilities in terms of decoding capabilities.
5.2 Decoding Capabilities p. 10
The following speech media decoding capabilities are defined:
- AMR: All decoding requirements for the AMR speech codec as specified in TS 26.071, TS 26.090, TS 26.073 and TS 26.104) including all 8 modes and source-controlled rate operation TS 26.093.
- AMR-WB: All decoding requirements for the AMR-WB codec as specified in TS 26.171, TS 26.190, TS 26.173 and TS 26.204 including all 9 modes and source-controlled rate operation TS 26.193.
- EVS: All decoding requirements for the EVS codec as specified in TS 26.441, TS 26.445, TS 26.442 and TS 26.443 as described below including functions for backwards compatibility with AMR-WB (TS 26.446) and discontinuous transmission (TS 26.450).
5.3 Encoding Capabilities p. 10
The following speech media encoding capabilities are defined:
- AMR: The encoding requirements for the AMR speech codec as specified in TS 26.401, clause 73 [21], 3GPP TS 26.404 [22] and 3GPP TS 26.405 [23].TS 26.403, TS 26.404 and TS 26.405.
- AMR-WB: The encoding requirements for the AMR-WB by one of the following methods:
- EVS: The encoding requirements for the EVS codec by one of the following methods:
- eAAC+: The encoding requirements for the AAC+ audio codec as specified TS 26.401, clause 73 [21], 3GPP TS 26.404 [22] and 3GPP TS 26.405 [23].TS 26.403, TS 26.404 and TS 26.405.
- AMR-WB+: The encoding requirements for the AMR-WB+ audio codec by one of the following methods
