To watch TV on your PC you need a TV tuner. You have two choices. There are usb sticks and pci cards. The pci is an internal circuit board that goes inside your computer. The pci card is very easy to install. Literally just open the computer and pop it into an available pci slot. Then you will need to install the software that came with the usb stick or pci card. Next attach an antenna to the pci card or usb stick connector. You can scan for channels, save favorite programs, and setup recording schedules. There will also be a program guide to let you see what shows are coming up. If you don't want to do all this you can subscribe to an online on demand service to get programming as well if you have broadband or access to a wifi network.
