Summary:
|
This amendment to ISO/IEC 13818-1:2015 specifies the carriage of 'Green metadata' in MPEG-2 transport streams. The amendment does not specify carriage in program streams. Green metadata component is specified using a new stream_type and is associated with media component to optimize display power consumption. Carriage of this metadata consists of a "static" part, which applies to an entire program, as well as a "dynamic" part, which can change for each media access unit. "Static metadata" is specified using a descriptor in the program map table while 'dynamic metadata' is specified using the private table syntax.
