1. 3 2 4 Subcarrier delay Subcarrier delay fo frames Figure 7 Multicon Gyda view of the Subcarrier delay setting The Subcarrier delay setting will add entire frames to the delay through the module The range is 0 7 frames For strictly periodic signals like Black burst and Tri level the delay is not important as such There are however two good reasons to care about this delay 1 A subcarrier delay of at least one frame must be added in order to use negative phase delays The exact same phase between input and output can be achieved by using a positive phase delay instead it is just a matter of how one likes to think about it 2 The subcarrier of the analog video sync outputs has eight different phases i e it takes eight frames to complete a full cycle Most modern equipment like digital frame synchronizers doesn t need or use the subcarrier phase but many video DACs do Matched subcarrier phases will be necessary to do seamless analog switching between 3 2 5 Linear time code The linear time code LTC is de embedded from the video input When video delay phase is changed by adjusting the Phase delay and Subcarrier delay above the LTC will automatically be delayed the same amount as the video It is possible to add an extra delay to the LTC relative to the video outputs This delay can then be either positive or negative given as a number of 48 Hz audio samples But once again the negative LTC delay can not be larger than

The factory reset is a four step procedure 1 Pull the main card out of the frame and set the two DIPs labelled F RESET and OVR to their On positions 2 Re insert the card into the frame The Status LED will now be a permanent orange colour No further waiting is needed after seeing the Status LED lit up orange 3 Pull the card out of the frame again and return the DIP F RESET to its Off position and set the OVR to the desired mode of operation 4 Re insert the card into the frame and it should now boot as normal again It is only at the end of this boot up that the settings are actually reset and to ensure that the new settings are stored properly it is important that the card is now kept powered for a few seconds after the Status LED has turned green The card will start to operate as normal with the new settings right away nevion com 12 SPG AVA DMUX Rev 0 3 2 Detailed control in Gyda mode All functions of the card can be controlled through the Multicon GYDA control system The Multicon GYDA has an information page and a configuration page 3 2 1 Information page SPG AVA DMUX R SDI out Pa SDI out2 AES 11 ABS LT Electrical Electrical input signal detected Optical input Loss of signal Reclocker Locked Phase delay O samples Video in Electrical Input frequency lock Sot master Tri level standard P20 50p 595 Black Burst standard SO Hz PAL BG BO Hz NTSC 10807251 Error counter 35591 Reset Si
3. The switching is always latching This means that when both physical inputs are missing then the module will look for a valid input in the background But if there is a signal on the physical input selected as first fallback then the module will not go back to the input selected as main unless the fallback disappears The user can however force the module back to main by pressing the latch Reset button Hold time and lock time can also be adjusted These specify how long a signal can be missing before the next input in the prioritized list is attempted and how long a lost signal has to be present before it is considered OK again respectively Main Electrical Video in Backup 2 Latch Reset Lock time fEo0 ms Figure 9 Multicon GYDA view of electrical input selected manually Mode Auto Nain T Video in Backup 1 Electrical Hold time foo ms Latch Reset Figure 10 Multicon GYDA view of the auto mode input selection 3 2 Output switch The board has four SDI outputs organized as two pairs of inverting and non inverting outputs Each pair can be routed either directly from the re clocker Through or via the processing unit Processed When Processed is selected the output can also come from the internal video generators They can act as fallback when video input is missing or the module can be used as a standalone generator This is controlled from the Video in block described the previous chapter
