Almost all Local TV stations are still using HDV as their standard and their cameras are tape.
That may change in the future but for now that is the reality. I have a number of friends that work in the TV industry in Atlanta, one is a award winning cameraman. He is still using a tape based camera (worth well over $10,000 and broadcast quality) and editing with AVID (the industry standard for many years).
You will not find a camera that will shoot good enough video for Television for under $6000.
Not that you can't shoot with a lesser quality and have that broadcast, but not on network television.
It really depends on what kind of work you are going to be doing for TV. If it is commercials then you will need the best equipment possible as the competition already has it

As far as format for broadcast goes every station will have options, the Apple Animation codec is very popular as the quality is excellent and can be easily edited. Others will take m2t files or even DV AVI for standard definition broadcasts. As Steve says, it is best to contact the stations you will be working with to see what formats work best for them and what they will accept.
Please let us know how you progress and what the TV people have to say
