If by music and video sites, you mean web servers you can access with a web browser, then the protocol in use is the one you see at the beginning of the URL within your web browser, ex.:


. It is plain HTTP (i.e. 80/tcp) or HTTPS (i.e. 443/tcp).


There are many network protocols at play. Some at the network layer (IP), some at the transport layer (TCP / UDP). Then there are formats or codecs for the media such as mp3 and mp4 and webm.
