High Definition Television 3Gbps Serial Data Interface
And source image format mapping
1 Scope
This standard specifies the mapping of the TV source image format at a rate of 3Gbps serial data interface (3GSDI), and
Embedded audio data, ancillary data, stream ID in the 3GSDI on the transmission method.
This standard applies to high-definition television program production and program exchange of 3Gbps serial data interface, and can be used as design, production, test
The technical basis for the production, maintenance and maintenance of high-definition television program production systems and their equipment.

3 direct mapping of source image formats
3GSDI data sources should be specified in Table 1 non-compressed 10bit or 12bit video signal, or packet data.
Auxiliary component signal Alpha channel, referred to as A channel. May be available as an option with the R'G'B 'or Y'C'BC'R video signal
Now. The interface containing the auxiliary component is identified as R'G'B 'A and Y'C'BC'RA. In this standard, if the A channel component exists, it should
Has the same characteristics as the Y 'or G' channel defined in the source image format.
