Embedding media player with streaming TV (Capturing streaming for a preview?)

Hello,
let's say, I have a web page where there is a link for the streaming TV. Instead of just having a hyper link, I want to embed a media player to preview what is playing on my streaming TV. I was thinking about when someone uploads my page, it makes a call to my streaming server and captures some streaming data which I'll use to preview. This preview will give some idea to the user, what is playing on the streaming TV. Do I have to incorporate some kind of middleware or some other technology??? any suggestion will be welcomed!!!
