Multiplexing and Transmission Media


MULTIPLEXING

Whenever the bandwidth of a medium linking two devices is greater than the bandwidth needs of the devices, the page link

can be shared. Multiplexing is the set of techniques that allows the simultaneous transmission of multiple signals

across a single data link. As data and telecommunications use increases, so does traffic.

About Project

Existing System
The Existing system in the organization involves maintenance of phone numbers of all the people working in any organization. Whenever the administrator want to have the communication with his subordinates, he have to look up the corresponding phone numbers, dial up and talk to them which is a time taking process. If the phone number is not available he have to take the help of other people. When a person starts to interact with the system, a bookkeeping system is used in order to know the login time a ....etc

Abstract

Businesses, schools can benefit greatly from technologies that enable information sharing through videoconferencing systems. Researchers at the University of Pittsburgh have developed a highly programmable and replicable solution. Using an IP-based network connection, small electronics and application programming interfaces of the Java Media Framework (JMF) v2.1.1, developers have created a flexible videoconferencing system that permits users to connect to one camera or many, remotely control a camera's pan and tilt angle and adjust ....etc

In the today's cyber world, we are largely dependent on computers. With the advancement of technology and complexity of computers, the need for massive storage is mandatory. Hard disks have been a major storage media for the past several years. Hard disks continue to shrink in size, gain increased storage capacity and increased transfer speeds.

The focus of development has been on increasing the density. But this may ultimately lead to saturation to atomic levels one day. Hence in this paper, on the basis of domain theory, different states h ....etc

This protocol controls telephony gateways from external call control elements called media gateway controllers or call agents. Converting among the audio signals carried on telephone circuits and data packets carried over the Internet or over other packet networks is done by telephony gateway. According to the call control architecture assumption of the MGCP the call control intelligence is outside the gateways and handled by external call control elements and these call control elements, or Call Agents, will synchronize with each other to send ....etc

INCREMENTAL MODEL ON MEDIA PLAYER
Definition of Incremental Model
> The incremental model combines elements of the linear sequential model with the iterative philosophy of prototyping.
> Incremental model is used when the staff is not sufficient. As in my project staff is not sufficient I developed basic needs of the project.
^ In First Incrememt we are giving the basic structure for the media player.
> it consists basic features ....etc

The Megaco protocol is used between elements of a physically decomposed multimedia gateway and is the result of cooperative efforts of the IETF and the ITU-T Study Group 16. The protocol definition of this protocol is common text with ITU-T Recommendation H.248. There are no functional differences from a system view between a decomposed gateway, with distributed sub-components potentially on more than one physical device, and a monolithic gateway such as described in H.246 . The Packet network interfaces may include IP, ATM or possibly ot ....etc
