Universal Mobile Telecommunications System (UMTS); LTE; Television (TV) over 3GPP services; Video profiles (3GPP TS 26.116 version 13.1.0 Release 13)

Scope

The present document specifies requirements and guidelines on video source formats (frame rate, resolution, aspect
ratio, colorimetry, bit depth…) and encoding parameters (codec format, random access point period, SEI messages…)
for different types of TV services, including linear TV, catch-up TV or on-demand services. A limited set of Operation
Points (e.g. SDTV, HDTV…) are defined to provide confidence to content providers/broadcasters on the quality of
experience offered by 3GPP services when used for TV-like distribution. Operation Points define format and encoding
restrictions, but may also be viewed as compatibility points for UEs.
In particular, the Operation Points defined in the present document may serve as the primary tested configurations for
TV centric video distribution. The initial set of Operation Points are defined based on the analysis and findings in the
technical report TR 26.949 [2].
In addition, in the context of DASH operations, not only the main distribution format are defined, but also a subset of
spatial and temporal resolutions. In order to minimize testing for seamless switching experience, suitable lower
resolutions of distribution formats are defined. Furthermore, to compensate congestion situations, a minimum service
quality is defined in order to provide service continuity.
