How can you broadcast TV over the internet?

Here's what you'll need. A source for TV programming. Jacked into a "TV card" in a computer (to convert the video w/audio into a digital format that can be treated as a data stream), and a high speed link to some ISP's server that will be fast enough to handle the data stream. And the real trick is the server connection. The streaming of video programming onto the web requires an ISP that will "tolerate" the (continuous) high data load. The user will have to have a subscription to an ISP that will support the desired activity. And the person on the other end will need similar connectivity. The answer is designed for one-to-one program transmission. Hit the www and talk to some compter types for more information. Certainly, there's WikiAnswers. If someone wants a web site that allows for a number of users to connect, a different set of rules apply. Tons of computer power and connectivity will be required and laws will come into play. Perhaps more questions on the boards will be required. Read the article on streaming media posted by our friends at Wikipedia, where knowledge is free. It's a great place to start.
