0  Introductionp. 6

In this Technical Report, we study the architectural enablers and extensions to the 5G Media Streaming Architecture for edge media processing. It covers aspects such as discovery, configuration, execution, and management of media processing in 5G to address the needs identified for example by the XR5G and FLUS items.

1  Scopep. 7

The present document is a study of use cases for multimedia processing in the edge and the potential 5G media streaming architecture extensions to enable them.

2  Referencesp. 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.
