not that i have any experience starting a company, but wouldn't it better for you to find a job at a cable company for a time and get to know the industry first? i don't know much about cable tv industry, but it seems to rely quite a bit on connections..
This. It would be better for the author to understand the legal requirements and the legal history of cable TV. The technical side is only a small part of the equation here. He would be dealing with regulations at local, state, national, and international levels.
