Abstract
A program map table in a transport stream comprising an elementary stream identifier indicating a particular elementary stream, a high dynamic range flag indicating the presence or absence of high dynamic range content within the elementary stream, and a wide color gamut flag indicating the presence or absence of wide color gamut content within the elementary stream.
Claims17
A program map table in a transport stream, comprising:
- an elementary stream identifier indicating a particular elementary stream within a transport stream;
- a high dynamic range flag indicating the presence or absence of high dynamic range content within said elementary stream;
- and
- a wide color gamut flag indicating the presence or absence of wide color gamut content within said elementary stream.
1 more element
A method of encoding a digital video, comprising:
- receiving a video with high dynamic range content and wide color gamut content at an encoder;
- converting said high dynamic range content and wide color gamut content prior to encoding using one or more pre-processing operations at said encoder;
- encoding said video into an elementary stream at said encoder;
- generating a program map table comprising a high dynamic range flag and a wide color gamut flag, said high dynamic range flag indicating the presence of said high dynamic range content in said elementary stream and said wide color gamut flag indicating the presence of said wide color gamut content in said elementary stream;
- and
- including said program map table and said elementary stream in a transport stream.
3 more elements
A method of decoding a video, comprising:
- receiving at a decoder a transport stream comprising a program map table and an associated elementary stream;
- reviewing said program map table at said decoder for a high dynamic range flag and a wide color gamut flag;
- and
- decoding said elementary stream when said high dynamic range flag and said wide color gamut flag indicate that said elementary stream contains high dynamic range and wide color gamut content and said decoder is configured to process high dynamic range and wide color gamut content.
