Video conferencing DC is a form of telecommunications in which individuals may utilize Internet services to speak via video. The service allows numerous locations to connect to one central communications hub and speak to each other through a connected network. This is beneficial in business and in law enforcement.
Is It the Same as Videophone Calls?
No, isdn video conferencing is vastly different from a standard videophone call. A standard videophone call connects a simplistic network service in which two people may speak via microphone and see each other through a web camera. ISDN video conferencing is connected directly to a video telephony system which is more complex than a simple video chat option.
How Does it Work?
ISDN video conferencing utilizes video and audio stream compression. Through this form of compression, the code for both audio and video are transmitted faster and over further distances. A digital stream breaks the transmissions into binary code, which is sectioned into packets and then transmitted over the ISDN network.
Video conferencing DC Components
In a ISDN network utilizing video conferencing; a web camera is used to capture images to transmit through the network from each participant of the video conference. These images are displayed on a variety of options such as a projector, flat-screen television, or a standard computer monitor.
Audio is transmitted and captured through microphones and heard through speakers connected to a computer. The data-transfer process is based on the option the owner selects such as a digital telephony network or through a LAN network connected to the Internet.
Types of ISDN Systems
ISDN videoconferencing options have two standard options. The dedicated system encompasses all components in one system. These systems are typically controlled by one console within a controlled environment.
The hub or center for these communications has multiple cameras situated in areas where they can adjust or follow the speaker. In dedicated systems, a projector is used to display the video images. These systems are used most often by large-scale corporations, law enforcement agencies, and by some legal professionals in law firms.
Desktop Systems
Desktop systems are smaller-scale options for ISDN systems. They are typically set up and connected to one standalone computer. With these systems are capable of operating multiple cameras, microphones, and sound systems.
