I like many vp50 owners are slowly running out of hdmi ports. We have to resort to external switches that don't integrate that well. It means more remotes
and more inportant the loss of settings per port. Now i have been thinking of a way they you can solve this in a very nice way that doesn't mean you have to
build 7 or 10 or ... hdmi ports on your next scaler but reuse hardware that you already sell.
You sell a rs232 controller 4 ports switch and the vp line of scalers both have rs232 so they can interact. Only software changes need to be made and as far
as i can see (i can't be sure) this can be done seemless the end user should not even know he doesn't have say 7 ports instead of 4.
Idea : vp50 now has 4 hdmi ports, when a vp4 unit is attached to port 4. Extend the menu from htmi1 to hdmi7. When 4 to 7 are selected just pick input 4 and send
a switch to 1 signal to the switch. when 5 then 2 to the switch etc etc. Since you now 'know' hdmi4 (really port for but with external on 1) is not the same as htmi6 (real
port 4 but external on 3) you can also support settings again on that port.
The end result would be that the user sees 7 hdmi's and they all act the same with full settings support and fully integrated. This also means for installers alot easer since
the vp50 control protocol could not support hdmi1 to hdmi7 and just 'abstract' the slave switch making it easer to integrate.
This could also be used with switches that have more inputs and even on the output side (since you can only have 1 active anyway). The nice thing is that you can extend this in many ways and the products keep their own value the switch (made by you or oem) can be sold on its own.
Please consider that people who use $3000 or up external scalers will probably run out of hdmi inputs and even outputs and adding 1 or 2 ports to a next scaler design is
a bad way to fixing the problem maybe this is a good way with low cost on your side and a very flexible setup for end users.
Hope this makes sense, i am a software designer by trade so i am more than willing (with the dutch importer) to beta test think more on how this can be done.
