how can you download 2 things at the same time - they run along side each other, a certain part of the bandwidth is reserved for cable tv, and the rest is left for the cable modem.

i know here in Australia, we have a big telstra box which splits the cable and handles all this quality of service stuff.

Many Cable Companies use SCDMA and TDMA technologies to do so.
The data pass through a modulation profile at different frequencies.
For the internet .. u have specified downstream and upstream frequencies and your cable modem tuner locks the specified frequency for the internet ..
I think u got it
