1  Scopep. 7

The present document provides a study of stereoscopic 3D video services over 3GPP networks and terminals. Technical definitions, use case descriptions, working assumptions, subjective tests results and technical studies are presented.
This document identifies the gaps within the Release 10 3GPP specifications in order to enable the implementation of the mobile 3D video use cases.

4.1  Introductionp. 10

This Technical Report provides a study on mobile 3D stereoscopic video in 3GPP. Use cases and technical solutions are investigated regarding a variety of setups using 3GPP's streaming, multicast/broadcast, download and progressive download as well as conversational services. Clause 5 provides a definition of the stereoscopic 3D video technologies and terminology as well as a video codecs performance comparison. Clauses 6 and 7 focus on use cases for which the working assumptions and the operation points are defined before providing a technical analysis, whereas clause 8 provides a set of use cases in which further study is required so as to identify the gaps. Clause 9 introduces subjective tests conducted on a 3D capable mobile terminal and clause 10 presents a generic approach for 3D content adaptation depending on the client terminal charasteristics. The conclusion summarizes the recommended way forward for the introduction of 3D stereoscopic video support in 3GPP specifications.
