<br> is on the threshold of getting cheap.<br><br>d) The DRM community also has a long term plan to get rid of analog HD outputs,<br> forcing boxes to down-res the analog.<br><br><br>So if you are investing, you must first consider that the "stand alone PVR"
<br>market, while not nothing, has remained modest. However, the hardware encoder<br>chips able to do HD will remain in high demand for the camcorder market, so<br>they will be available. Those all go directly from sensor, so A2D is not needed.

<br>I hope somebody does, but they will sell much smaller numbers than they would<br>in an open world.<br><br><br>(Well, not quite, because in an really open world there would be no need for capture<br>cards, so they would sell none!)

i've heard they tend to be ~3 MHz wide, have a 2 Mbps data signal, and reside somewhere between 0 and 100 MHz.<br>
eventually having myth follow the unencrypted digital channels around the spectrum automatically would be nice.
