Advertisements No, I meant something like this (encryption aside). Analog Signal Timeline: Coax transmission comes into electronic tuner. Tuner is set to filter out ONE frequency. Info encoded in filtered frequency is processed by video electronics. Video electronics outputs TV signal to plugs. Digital Signal Timeline: Coax transmission comes into receiver. Receiver reads ALL frequencies and dumps it into computer (RAM most likely). Software in computer extracts whatever "frequency" it wants to look at. Info encoded in extracted frequency is processed by software. Software sends data to video electronics. Video electronics outputs TV signal to plugs. In the second method, a faster CPU (running parallel software?) can theoretically extract as many "frequencies" (if that still has the same meaning) as it is capable of from the RAM. The issue is, how many streams can you write to a HD at once...maybe it will be more with SATA 6GB later...or even more with large SSD's of the future. This may be a bit off as I'm just guessing mostly as to what it means for a transmission to be "digitally processed".
