Summary:
|
This amendment to ISO/IEC 13818-1:2015 specifies the carriage of layered HEVC (also called Scalable HEVC) in MPEG-2 transport streams. Similar to other recent amendments, this does not cover carriage in "program streams". The amendment defines four new stream_type values to signal base layers and spatial as well as view enhancements. It also defines a 'hierarchy extension' descriptor to enable enhancement layer assembly and an 'operation point' descriptor which allows receivers to select the streams that match their resources and rendering capability prior to decoding the components of a program.
