right, but i also have the cable modem line and an old school black coax cable coming from the box. i figured they would put some kind of filter on the "internet" line that would block out the tv portion

Yeah. Some older cable systems did require a filter. But the filter could be "inline" with your regular cable TV. What it did was clean up the signal so that the two didn't interfere with eachother. It didn't actually block either one.
You have always been able to simply put a splitter on the end of a cable and plug one into your TV and the other into your cable modem. If a filter was needed, it simply had to be somewhere along the line that went to your modem (but it didn't really matter where along that line).
If you have a cable service that provides digital cable to your area, you shouldn't need any filters and you should be able to plug cable modems and cable TVs into the cable at any point with no problems. Ultimately, it's all just one feed into your house.
