GB/T 32631-20163Gbps serial data interface and source image format mapping for high definition television (English PDF)

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.
