Re: A New Approach to Components in a Digital World - Something to think about
Hi Robert,
(Long post alert....)
The two box solution does give much greater flexibility in upgrading and matching the needs of a system. For example if one was happy with their existing pre-pro/receiver but wanted HDMI switching to their system a HDMI switchbox can be added to take care of this without having to scrap the pre-pro/receiver they are happy with. If the needs were for video processing to handle a constant height front projection system an appropriate scaler (such as the DVDO or Lumagen) could be added to the existing pre-pro/receiver.
However, this does add some additional challenges to the system. One of the big ones is as you mentioned the everyday usage of the system. Instead of having a single box running everything you know have two. The user know needs to turn on/off both boxes and switch audio inputs on one box and video inputs on another to keep everything in sync. The complexity of using this more flexible setup increases.... the WAF decreases.
"I hope to see some of them jump in with some alternative control suggestions."
Macros in a remote is one way of dealing with the need to syncronize two boxes to each other. This can work pretty well but does have some downsides. The most obvious is it only works with that one remote. If a person uses a different remote the audio and video get out of sync again as there is nothing to tie them together. Or if one switches inputs on the pre-pro/receiver front panel itself, say when loading a DVD, the audio and video are again out of sync. Another potential downside with macros is in simple IR reception. This likely won't be an issue for you with the IR flasher system you will be using, I use the MX-3000 as well, but for those that still have to aim their remotes at the systems while performing macros sometimes a code gets missed which again results in out of sync audio and video.
When using a two box system in this manor it still is fairly obvious that it is a two box system as you have to keep in mind only using the macro programmed remote, aim it and wait for macros to complete, don't touch the front panel of the pre-pro/receiver, etc...etc..
Because of all of this I build a little device which integrates two box systems together so they work together no matter what. Turn on your pre-pro/receiver, by front panel or any IR remote you want, and the video box turns on. Switch inputs on the pre-pro/receiver, again by front panel or any IR remote, and the video box switches inputs to match automatically and with no worries about missed IR commands or anything like that.
My box works by using the RS232 serial control port that is on many different pre-pro/receivers and on numerous video scalers and video switch boxes. In effect it watches, and in some cases queries, the pre-pro/receiver for power status and input selected and when they change it sends the appropriate RS232 command to the video switch/scaler to keep audio and video inputs in sync. Because my box is actively looking for feedback from the receiver/pre-pro it does not matter how the receiver/pre-pro is controlled, the second video box will stay in sync. It makes the syncing of the two boxes really seamless so they act as one all the time.
There is another potential problem of two box systems that should be considered. That is simply getting feedback from your pre-pro/receiver about what it is doing... volume setting and so on. If the pre-pro/receiver is in line of site then one can just look at the front panel to see what is going on. However, if the pre-pro/receiver is located out of the line of site the user has likely relied on the pre-pro/receivers On Screen Display for feedback. If all the video sources are routed through a seperate video box the user has lost the On Screen Display from the pre-pro/receiver which is likely going to be a problem. Same problem for video sources that can't be routed through the existing pre-pro/receiver such as HDMI or SDI.
There are a couple of ways of dealing with this.
The first is to run the video output of the receiver/pre-pro into a different input on the video box and when needed change inputs on the video box just to see the OSD. This works but is fairly ugly in practice since it makes control more complex and is of course distracting to have to drop your active video input, switch to another input just to see volume level or whatever, then switch back.
A second way to deal with this is to get a small say 7" LCD display like what is used in car video systems and run the OSD output from your pre-pro/receiver to that. Put the LCD in line of site of the user and they can simply look at it to see what the pre-pro/receiver is doing. Doing this can work well, I have used it in my theater, but one typically needs a manor of turning the little display on/off by remote if they have a 'bat cave' of a theater to avoid un-needed light polution when they don't want the LCD display on.
Lastly for very specific systems I have just added a new function to my box in the latest software release to solve this problem. Lumagen video scalers have the ability to basically put up messages On Screen via the RS232 interface. Using this special feature of the Lumagens my box can take whatever is on the Front Panel display of a Lexicon and make the Lumagen display it On Screen as an overlay. This way even if no video sources passes through the Lexicon at all I still get an OSD from the Lexicon of whatever is on the Front Panel. As you know in a Lexicon the entire box can be configured via the Front Panel display alone. This feature is specific to the combination of Lexicon's and Lumagen scalers for now. A few DVDO owners have requested this sort of feature be added to the VP50 and if it is added I will add support for the DVDO to my box as well. If there are times when one doesn't want this function active they can simply turn off the front panel of the Lexicon (FP button on the remote) and the On Screen Display function turns off as well. I have a couple of Quicktimes up on my site showing this in action.
Thanks,
Shawn
