The Importance Of Video Communication
Video has been an important media for communications and entertainment for many decades. Initially video was captured and transmitted in analog form. The advent of digital integrated circuits and computers led to the digitization of video, and digital video enabled a revolution in the compression and communication of video. The growth and popularity of the Internet in the mid-1990’s motivated video communication over best-effort packet networks. Video over best-effort packet networks is complicated by a number of factors including unknown and time-varying bandwidth, delay, and losses, as well as many additional issues such as how to fairly share the network resources amongst many flows and how to efficiently perform one-to-many communication for popular content [26]. …show more content…
For example, video communication application may be for point-to-point communication or for multicast or broadcast communication, and video may be pre-encoded (stored) or may be encoded in real-time (e.g. interactive videophone or video conferencing) [29]. The video channels for communication may also be static or dynamic, packet-switched or circuit switched, may support a constant or variable bit rate transmission, and may support some form of Quality of Service (QoS) or may only provide best effort

It requires streaming media, including telephony, video teleconferencing applications online TV services and web-based features push-to-talk. RTP was developed from transport working group audio-video work www engineering work (IETF) and primary composite with RFC 1996. As 1889, replaced from RFC 3550 in 2003. Most text through its memorandum is generally identical to power RFC 1889 where it becomes obsolete.

694 Words | 3 PagesIntermediate nodes, when overloaded, drop packets and hence the number of dropped packets is the largest compared to the other modes. Mode 1 gives the best performances is due to the fact that the sources distribute their flows on all available paths from the beginning hence reducing the probability of overloaded queues. However, it is observed that mode 3 tries to balance the load of a congested path on the other paths does not succeed in reducing the drop rate when compared to a simpler approach such as mode 2, at least for small network

The protocols cover various issues such as authentication, error detection and correction. Popular network communications protocols used are the TCP/IP and User Datagram Protocol (UDP), while TCP is connection oriented once a connection is established, UDP connectionless Internet protocol. The model for information exchange includes the data source which generates the data to be transmitted, Transmitter which converts the data into transmittable signals, Transmission system which carries the data, Receiver which converts received signals into data and Destination which takes incoming data. TCP/IP uses
