1  ScopeWord‑p. 6

The present document provides reference test material and test results for improved usability of technologies in TS 26.118.
The specification TS 26.118 includes several VR media profiles for video and a single media profile for audio with different configuration options. The specification focuses primarily on interoperability requirements for VR360 applications, but does not address performance characterization of the solutions. In order for content providers and the rest of the ecosystem to be able to select and configure the technologies defined in TS 26.118 and to generate content for streaming applications, collecting such information would be most valuable.

2  ReferencesWord‑p. 6

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.
