1. What kinds test patterns should be offered by such a HDMI Test Pattern Generator?
I'd like to be able to load in .bmp files, creating pixel by pixel definitions of patterns in arbitrary resolutions.
2. What type of audio outputs and audio test signals should be provided ?
Allow it to hook to a PC sound card to generate tones. Support 7.1 channel sound. I'd like a HT tester, not a video tester.
If you want to do onboard sound generation, make sure you can get down to 5Hz (to test for rattles in the room) and up past 20Khz.
3. What other features and /or connectivity should be offered ?
USB, because as you can guess, I want to use a laptop to control everything. I have to have a laptop anyway, after all.
4. What would be the most you’d be willing to spend for such a device, assuming that it provided high quality output signals at various resolutions including 1080p ?
Well, if you use a laptop for all the settings and controls, USB for power and data, and include custom software to talk to it, and have a lot of image and sound files on an included CD... $250? $200?
