Interworking of the different real-time terminals like mobile phones and PDAs requires unified signaling, a protocol for introducing different capabilities of terminals. A PDA with integrated camera and conferencing support has to know how to talk to a plain old phone. To fulfill this requirement, a Session Initiation Protocol (SIP) was created. It is very scalable and extendable protocol that can be used in negotiation with almost every service on the Internet.
Exponential increase of connection bandwidth has created new opportunities for audio and video delivering. Couple of years ago a new protocol for streaming audio was developed. This protocol called RTP (Real-time Transport Protocol) is very scalable for different wired and wireless networks and can be easily extended and implemented to new frameworks.
For example, RealPlayer is one of the most well-known methods of delivering streaming audio and video through the Internet. Its core is based on a protocol also known as RTSP (based on RTP) that supports media transmission on different protocols, like UDP, multicast UDP and TCP.
Gaming is maybe the most important application area of the real time world because of its high potential of consumers. On the Internet, people buing for their entertainment will be the key element of the future-driven business making. Virtual worlds with different parts dedicated for action, romance, shopping and social life will be the places people will spent most of their spare time and money.
