Here is the scenario - best explained visualising a TV.
For example, there are 9 destinations with 9 multiple cameras.
On a decent computer screen, the 9 destinations are shown in ONE window, i.e. 3 x 3 plus room at the bottom for controls.
Step 1: Now, if one clicks on (example) destination screen Number 1, it opens (enlarges) the current window to show the 9 multiple cameras.
Step 2: The user should be able to "go back" to the main screen without leaving the main screen.
In principle, a form of "big brother" if the terminology means anything, drilling down in 9 multiple locations.
Step 3: The biggest challenge: The above, which is viewable on the "main operator screen" - can be viewed on anybody´s computer. At the same time, the main "operator" is able to switch off any of the nine destinations.
Last: It should run on a general platform like youtube, etc - without proprietary software to be installed.
Big list... on paper with a pen easy to explain. I am looking forward to responses.
