Hi,
We're using a Sony DVS 9000 and when we have a feed that has close captioning on line 21 go trought the switcher, the CC ends up on line 22 coming out of the switcher. Does anyone have a fix for this?

Help or suggestions would be appreciated!
Thanks!
Marty

All Sony switchers are line delay switchers and their output will be one line delayed from house reference. Assuming that master control is using the same reference, the production switcher will appear 1 line late to master control which is why you get the one line shift and CC in line 22. Most facilities use a frame sync to correct the timing difference between switchers using the same reference. The reference output phase adjustment in menu 7333 is a separate BNC port on the switcher mainframe used to time an external device, it does not affect your program out and as pointed out, not available on the G series switcher. In menu 7331 there is a switcher phase adjustment, this adjustment moves the input TBC window of the switcher and affects all inputs. The adjustment range is dependent on format and is usually less than one line. This adjustment should not be used to fix an output timing problem. -Max

One more thought - is your switcher feed going through a frameshaker, TBC, or other device before it hits Master Control? If so, the problem could be there. Does your Master Control switcher have input phase adjustments for each input source? If so, you could fix the problem there.

Hi Bob, We checked that and nothing happens. We can move either buttons and the shift is still visible in Master. I imagine that we would see our image shift on the output as well while adjusting those settings but nothing. Not sure if those settings are enabled since there's no change.

[quote="mparadis"]Hi Bob, It's a little odd because when we adjust any of those settings on page 7333 (Ref Output Phase using the Line or the Time), nothing happens. In theory, I should see something move in my scopes right?[/quote] If you adjust it (the output where you're feeding PGM to Master Control), check at Master to see the shift. You'd only see it on your scope if you switched between EXT & INT reference.

In theory, I should see something move in my scopes right? Here's the software versions we currently have on the switcher: Menu: Version 4.01 PNL1: Version 4.00 DCU1: Version 3.00 SWR1: Version 4.00 I also downloaded firmware 7.22 from the Sony webiste but can't install. Thanks. Marty

[quote="mparadis"]Thanks Phil. That works but I still have a vertical shift when Master switches to our control room. Any idea why?[/quote] Again, menu page 7333 will allow you to adjust the output phase of the switcher outputs - you can use this to time your switcher output to master control.

[quote="mparadis"]Thank you all for your input. After looking into this a little more, we found out that the switcher is not timed correctly into our master control. There's a vertical shift when master control cuts to the control room. When looking at it on a scope, you can clearly see the shift. If I route the switcher's output to a DPS575, there's no more vertical shift and the CC is passing through on line 21. We're now trying to adjust our timing on the switcher but not sure where to do so. When playing with the Ref Output Phase on menu page 7333, nothing happens. At this point, we're just scratching our heads...[/quote] Ref Out adjust will not alter anything unless you are use this output as a reference to other devices. However you can change the relative timing of the switcher by adjusting the System phase in menu 7331. Hope this helps. Also just to let people know Ref Out is not availabel on an MVS8000G. Phil

Yes it is. One of the options discussed, was to provide the switcher with a seperate reference.

is the device providing reference to the switcher the same device providing reference to master control?

Ask you engineers if they can advance only your switcher genlock by one line.

My only other thought would be to check/adjust the Ref Output Phase (7333). Or, you might adjust the input phase (7332) of the captioned source.

Bob, thanks for your suggestions. We enabled the THROUGH mode on the specific inputs and outputs. We are not running the sources through a keyer. Unfortunately, CC is still on line 22. Any other thoughts? Thanks, Marty

Try enabling the THROUGH mode on the specific input that you're concerned about (menu 7332), as well as enabling the THROUGH mode on the switcher's output (menu 7333.3) If you're running the captioning source through a keyer, make sure that the KEY DROP mode is off.
