MVS8k Delay from PGM

Hi all,

I'm pretty new to this forum, have some questions on the MVS.

We're currently studying the possibility of upgrading from our operations of using 3x DVS-2000C to a single MVS-8000G.

We've specific concerns listed below...hope someone would help us..

1. Existing DVS-2000C has a 1-line input to PGM delay. As we sometimes chain our PGM one to another, it is important to have minimal delay, for our PGM output to a live LED screen.

Is there a delay spec for the MVS-8k's PGM output.

Will the delay increase as the M/E PGMs are chained one to another?

Also, will using the DME option board, or the external DME increase the delay, and by how much?

2. Is there a limit to how many M/E control panels that I could remote out to various rooms?

ie. To have different rooms having 1 or 2 M/E boards seperately, while I maintain a 4M/E full control in a master control room? Is this do-able?

3. We're totally new to multiple M/E operations, any specific things I need to be aware of?

Thanks everyone ! This is a great forum!

I don't know anything about pricing. Sorry. The resizers don't work on the background Bus, so if you want to do a DME wipe like you can on the 2000C (if you had the DME-3000 or DME-7000) you need the 3D DVEs. Remember though that the built-in Resizers don't have rotation. So if you ever want that you have to get the 3D. No worries, you can just buy, say, 2 channels of 3D and they work everywhere in the switcher. You don't have to buy them on an M/E by M/E basis like a lot of other switchers. The 3D channels are shared throughout the switcher. RE [quote="melvinchen"]Hi Rick, Thanks for your great help! Sounds like the MVS-8000G would be what we want to go...couldn't afford the 1-frame, cause of the Live LED screen. Thought of going with the Snell's Kahuna, but the interface is really quite different. We still own 2 sets of Switchpack from them, that's barely two years old and trying to let go to any Snell lovers...tat's besides the point, but anyway... One other thing to ask...will I need the DME to do box-in, Picture-in-Picture? Can the standard set do it, or the DME board ? Or should I get the external DME? I worked out a rough budget based on prices listed on Sony USA's site, is the actual price around those figures? We had planned for about Singapore $600k (USD$400k) for a 4 M/E + 2 + 1 M/E configuration, in 3 seperate rooms seperately. Would this be about sufficient in a SD-only configuration? Thanks! I still think this is the BEST forum for TDs![/quote]

Hi.... Wow! A DVS-2000C... I used one of those years ago. What a great switcher! Very under-rated..... To try to answer your questions..... With a few exceptions, there are two types of switchers: Minimal delay and frame-delay. Most minimal delay switchers have one-line delay from input to output. The Sony switchers are of this lot. The other kind is a frame delay switcher. The old Abekas switchers were like this as is the current Snell & Wilcox. There's not really anything inherently wrong with frame-delay switchers, it's just whether you want everything delayed a frame or not. The Sony MVS-800G (as were all Sony switchers) have a one-line delay from input to output, no matter how many times you cascade M/Es. If you go through a DME, you will addd ONE FRAME to that video's path. That does not mean if you go into a DME, that everything delays a frame, just the video that's in the DME. Thomson (what used to be Grass Valley), and most other switchers, work like that as well. Actually, your DVS-2000C was/is exactly the same. Sony's MVS series can have 4 control panels, of any type, connected to a single mainframe. I say any type because the 8000 control panel is completely modular. You can build virtually any type of panel. So, yes, you could have a 4 M/E panel one place, a three M/E panel in the next room and a couple of 1 M/E panels elsewhere. You could have four 4 M/E panels (if you have $$$). The individual M/Es on each panel can me active or inhibited. You can also choose whether inhibited means the lights will light but you can't push the buttons (just to see what someone else is doing) or be turned completely off. Sony has a very cool feature here. If you use with Multi-Program split M/E feature, you can put the "MAIN" and "SUB" outputs of each M/E on a different panel surface. Normally you have a toggle button to do this on a single M/E, but if you are only going to assign 2 M/E's to a room, you could have a 3 or 4 M/E panel for those two M/Es and have, say, M/E 1 MAIN on the top row, M/E 1 SUB on the second row, etc etc. VERY cool feature. Adding an M/E row to the panel is relatively inexpensive. There's nothing to "worry" about with multi-M/E operations at all. Just more of a good thing. Good luck! I'd stick with the 8000G. The operation will be very familiar to those that work your 2000C, so training time should be reduced (don't misunderstand -- there will be a learning curve, just not as bad as starting from scratch).
