We're entirely 720p here, which >was my choice. I'm sure you'll get a kick out of that ;) I'm confused... Perhaps you are constrained currently by the camera you are using to acquire video. I'm not certain that this is what you are trying to express, but I do have a few tips/observations. - Just because a display has more resolution than you can capture with a camera today, it does not mean you cannot use a lower resolution camera (i.e. 1280 x 720P), and then upsample to 1920 x 1080. This works quite well for 720P. - There are HDTV cameras that shoot 1920 x 1080P at 24 and 30 frames per second, which should be adequate for MANY applications. - As is the case with many forms of new media, it is not always necessary to fill the entire screen with one video stream. In the case of digital signage, video is OFTEN presented in a window along with non-Nyquist filtered graphics. As for playback performance, it really depends on what you are doing. Panasonic is shipping Plasma panels with built in modules to handle all of this . They can support MPEG-2 MP@HL playback, HTML graphics generation, and some forms of interactivity; another module offers a broadband connection that can be used to upload files to the display for play out. At NAB Panasonic also demonstrated a variety of Macs playing out HDTV to projectors. You can use a Powerbook, a desktop, or an Xserve. A couple of X-serves can now handle all of the storage and playback requirements of a film festival. I suspect that we will soon be seeing 17" and 20" G5 iMacs being used for digital signage applications. And yes I did get a little kick out of your 720P admissions. But this is just common sense for this application which is NOT just a video play out system, but an integrated mediua application that can take full advantage of the display capabilities to maximize the functionality of the digital sign.
