Nevion LIS-SDI SD-SDI LINE SYNCHRONIZER

The flashlink LIS-SDI line synchroniser synchronizes the output SDI to the Black&Burst signal with an adjustable phase relative to Black&Burst signal. The LIS-SDI deglitches the digital signal when upstream switching is performed. It is possible to correct false F (Field), V (Vertical blanking) and H (Horizontal blanking) bits in TRS sync words. The LIS-SDI has an option to shift the whole video picture up and down with respect to the Vertical sync.

The LIS-SDI can operate in two modes, with or without line sync (switch 3 or lsync on/off command). When the line sync mode is off the card is used as a deglitcher. Then the output phase is not adjustable.
It is recommended that the Black&Burst is connected also when the card is just used as a deglitcher. The Black&Burst will insure that the output frequency is correct even if the input signal is lost. When the line sync mode is off, the SDI output is delayed by half a line with respect to the first SDI input detected. Any SDI used as input to the deglitcher must not be off phase by more than half a line with respect to any other input presented to the deglitcher.

When the line sync mode is turned on the LIS-SDI is used as a line synchroniser and a deglitcher. The output is synchronized to the Black&Burst. The output phase is adjustable over a full frame with respect to the Black&Burst. The internal video buffer is only one line long. Therefore the phase of the output SDI must be from 41 samples to 1 line and 41 samples after the input SDI. The internal processing delay is 41 samples. It is important to know the phase of the input SDI signals.
