client to capture tv and put on website

i need some kind of sotware that gets the tv signal from a tv cuner card, and embeds it on a website, on real time. this website would be accessed locally, with a local server like xampp. it must work on FF or Chrome. it would be great if it was javascript based but you may use flash or java, or any other technology. your work is just developing the system to put the tv on the website; nothing more, nothing less..
