Video conferencing software facilitates initiating and conducting live conferences between two or more participants at different sites by using computernetworks to transmit audio, video and text data.
Today, video conferencing software is used by companies of all sizes to stay connected with global partners and employees, to increase productivity and to cut costs. Most video conferencing software let users communicate and share and collaborate on files.
How Video Conferencing Software Works
Video conferencing and Web conferencing software applications enable both point-to-point (two-person) and multipoint (three or more participants) video conferences.
In many ways a point-to-point videoconference is similar to a phone call with video of the other participant. Each participant has a video or Web camera, microphone and speakers mounted on his or her computer, and as the two participants speak to one another their voices are carried over the network and delivered to the other’s speakers. Whatever images appear in front of the video camera appear in a window on the other participant’s monitor.
Multipoint Conferencing Software
In a multipoint conference, the video conferencing software enables three or more participants to sit in a virtual conference room and communicate as if they were sitting right next to each other. Video conferencing software with support for multipoint conferences has become popular with businesses as a way to save on travel costs and facilitate team collaboration among employees in disparate geographic locations.
- video encoding
In video editing and production video encoding is the process of preparing the video for output, where the digital video is encoded to meet proper formats and specifications for recording and playback through the use of video encoder software. Also called video conversion.
- video memory
RAM installed on a video adapter. Before an image can be sent to a display monitor, it is first represented as a bit map in an area of video memory called the frame buffer. The amount of video memory, therefore, dictates the maximum resolution and color depth available. With a conventional video adapter, the bit […]
- video mode
The setting of a video adapter. Most video adapters can run in either text mode or graphics mode. In text mode, a monitor can display only ASCII characters. In graphics mode, a monitor can display any bit-mapped image. In addition to the text and graphics modes, video adapters offer different modes of resolution and color […]
- video overlay
The placement of a full-motion video window on the display screen. There are various techniques used to display video on a computer’s screen, depending on whether the video source has been digitized or is still in analog NTSC format. Since computer monitors are generally analog, NTSC video can be merged with signals coming from the […]
- video standards
There are a variety of video standards that define the resolution and colors for displays. Support for a graphics standard is determined both by the monitor and by the video adapter. The monitor must be able to show the resolution and colors defined by the standard, and the video adapter must be capable of transmitting […]
