Transfer of video and related data over serial data interface (sdi) links

A method comprising:

• converting video mix parameter data that is associated with video data into link-compatible video mix parameter data for transfer over a Serial Data Interface (SDI) link, the video mix parameter data having a first range of permissible values and the link-compatible video mix parameter data having a second range of permissible values, the second range being a range of values permissible for the SDI link and narrower than the first range;
• generating, based on the video mix parameter data and data range conversion, error data for transfer over the SDI link, the error data indicative of an error introduced by the data range conversion.

A data decoder comprising:

• an input to receive link-compatible video mix parameter data and link-compatible error data that are transferred over a Serial Data Interface (SDI) link, the link-compatible error data being indicative of an error introduced in generating the link-compatible video mix parameter data from video mix parameter data that is associated with video data;
• an error corrector, operatively coupled to the input, to apply the error data in converting the received link-compatible video mix parameter into recovered video mix parameter data that is associated with the video data.
