A video conference is a real-time, visual connection between two or more remote parties over the Internet that simulates a face-to-face meeting. Video conferencing is important because it connects you with people you can’t normally form face-to-face relationships with.
In its simplest way, video conferencing transfers static images and text between two locations. The most sophisticated transfer of full-motion video images and high-quality audio between multiple locations.
In the business world, desktop video conferencing is a key component of a unified communications platform that also includes calling and messaging capabilities. Standalone on-premises and cloud-based video conferencing platforms are available from numerous vendors supporting desktop and conference room-based video, as well as the ability to embed video conferencing into business applications such as telemedicine, customer service, and distance education.
The widespread availability of cloud-based services enables organizations to implement video conferencing with minimal up-front investment and leverage rapidly emerging AI-powered capabilities to improve audio and video performance. The video conferencing process can be divided into two phases: compression and transmission.
During compression, the camera and microphone capture the analog audiovisual (AV) input. The data collected is in the form of a continuous wave of frequency and amplitude. Represents the captured sound, color, brightness, depth, and shade. Once captured, the codec converts the data into digital packets, typically through compression to minimize bandwidth usage.
In the transport phase, packets are typically sent over the network to a cloud service provider and then sent to other meeting participants, combining voice and video from multiple participants.
When the packet arrives at the endpoint, the codec decompresses the data. The codec converts it back to analog audio and video. This allows the receiving screen and speakers to see and hear the AV data correctly.
