The development of a network protocol support, the media raises many questions. Datagram protocols, such as the User Datagram Protocol (UDP), send the river as a series of small packages. This is simple and effective, but the packages may be lost or damaged. Depending on the protocol, and the extent of the loss, the customer can be in a position to the data with techniques for the correction of errors that can interpolate to a lack of data, or can be abandoned. The Real-Time Streaming Protocol (RTSP), Real-time Transport Protocol (RTP) and the Real-time Transport Control Protocol (RTCP) were specifically for the media streams over the network. The last two are placed on the roof of the UDP.

Reliable protocols such as Transmission Control Protocol (TCP), the smooth running of each bit in the data stream. But they are doing this with a system of deadlines, and trials, the most difficult to implement. This also means that if the loss of data through the network, the media feed market stalls, while the maintenance personnel identify loss and forwarding of data are missing. Customers can buffer the effect of these data for the display.

Another problem is that the firewall is more likely to block UDP, TCP protocols. Unicast protocols, a copy of the stream between the server and each client. It is simple, but can lead to jobs that duplicate data on the network. Multicast Protocol commit themselves to a single copy of the press for a network connection, ie on the road between two routers in the network. It is a more efficient use of the capacity of the network, but it is much more complicated to implement.
