Streaming protocols

Option Description
Streaming protocols Specifies the protocols Windows Media Player can use to receive a stream. The Player receives streams through UDP, TCP, and HTTP. It can also receive multicast streaming. By default, all protocols are selected, which means that the Player tries to use each protocol to receive a stream. Because the Player can receive files by using a variety of protocols, it is recommended that you select all protocols. However, if your network implements a firewall that prevents you from receiving streams that use the UDP or TCP protocols, you may want to clear the UDP or TCP check boxes.
Use ports <port number> to receive data Specifies a particular port if UDP is the protocol used to receive streaming content. This option is useful if your network or firewall administrator has established a specific port that allows streaming content to pass.

Unless otherwise instructed, Windows Media streams try to pass through firewalls using the following default port for the selected protocol:

  • HTTP protocol. Port 80.
  • MMS protocol. Port 1755.
  • RTSP protocol. Port 554
