Signal Detection

Hello everyone,

I am working on a graduation project, for which I need to check the physical outputs of an AV device for correct functioning. Exactly speaking, HDMI, Composite/S-Video/Component Video and Audio connections.

I want to be able detect if the particular input is connected physically to the Video Capture card inputs and if there is a valid incoming signal from the device. (detect the type/format of the signal as well, if possible)

Is this doable with the BlackMagic Intensity Pro PCIe or Shuttle (USB) devices?
Through the provided SDK or Windows DirectShow APIs ?
Or any other methods or hardware that I can use for this purpose?

I have very limited budget and I want to make sure I spend it on the right card/hardware.

Thanks in advance.

Automatic mode detection
The automatic mode detection feature will notify an application when a property of the video
input signal changes.
This feature is supported on certain DeckLink devices.

You may switch sources and at the callback method of the comming video to check is you have error or not.

The sources that will return to you frames means that are connected.

Doing this way you can be stumbled by specific hardware/firmware behavior (or bug) when video input is 720p and any 1080 mode is applying by software to check possible incoming frames. Some new boards becomes blocked (I reported the issue before).

Since the guy talks about the Intensity Pro (HDMI, Composite/S-Video/Component Video and Audio) i have to tell that this method works on Intensity Pro.

Cheers!
