First, the Tv program (either prerecorded or captured dwell with a video digital camera) has to be transformed into a digital format that can be delivered as packets using the Internet protocol. When you browse a website, you are effectively making a temporary hyperlink between two computers so one can "suck" info off one other. Your laptop (the shopper) pulls info off the other, typically way more powerful computer (the server) by linking directly to an IP address that corresponds to the website you want to look at. The shopper and server have a brief, intermittent dialog by which the consumer requests from the server all the recordsdata it needs to build the web page you're taking a look at.

The Internet efficiently hyperlinks virtually all the world's computer systems as a result of all of them agree to speak to one another in the identical approach utilizing prearranged technical procedures called protocols.
As an alternative of utilizing the peculiar, standard, internet-based protocols for downloading (technically, they go by the names HTTP and FTP), streaming involves utilizing protocols tailored for simultaneous downloading and taking part in, corresponding to RTP (Actual-Time Protocol) and RTSP (Actual-Time Streaming Protocol).
