5.3.15. Extract Line
The HD-SDI and higher standards include the current video line number as part of the EAV extension words. The insert line submodule encodes the 11-bit line number in two of these extension words as defined in the SMPTE ST 292 specification.
This submodule decodes the data words and registers them when the Match TRS submodule indicates that the current words are LN0 and LN1 extension words.
