1 Scope p. 7

The present document specifies speech and audio media capabilities, operation points and media profiles for 5G Media Streaming in the context of 3GPP services and deployments. Speech and audio media capabilities, operation points and media profiles are also provided for usage in other streaming applications.

2 References p. 7

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.
