What does this sign mean when it is posted at the entrance of the cinema that you are thinking of spending your money and time at?

It means that the owner bought test equipment that will allow the technical staff to perform tests of the ‘HI/VI’ glasses and hearing equipment on a regular basis.

If they do those tests then they at least will know some important details, such as, does the equipment work, is it being maintained, or has it just been sitting in a box for the last month?

Here is what we mean by that.

It all seems so simple. Just make certain that all the equipment has perfectly charged batteries so that when I come with my friends to the movies, that I don't have to make a special production about getting the a closed caption set that works?

But like many things, not difficult, but detailed means that the test has to be on the list of things to get done, and there has to be someone who does it, and that someone has to know enough and care enough.

The Digital eXperience Guardian does two of these things: it creates a list (we'll test all the sound equipment on Tuesday, for example, and the picture equipment on Wednesday. It also steps a person trough the tests that makes it possible to tell if the equipment is working.

What it doesn't do is the actual testing. That is up to management to coordinate. But if they are clever they will make a display that proudly shows that they have done the tests.
