How video conferencing works

Today you have high-speed internet and 4G with 5G around the corner, and infrastructure perfect for video calling. The traditional way was to set up a separate room with video cameras, display screens, microphones, and computers with hardware devices for video switching. It was all very complex, expensive and one had to learn how to use it. Today, you can use VoIP technologies, your smartphone, or a desktop with a webcam and microphone to initiate or participate in a video conference through a simple app or desktop software solution. Then there is telepresence video conferencing that offers full HD Video with multiple displays to give you an “in the face, across the table” feeling.

You can conduct video conferencing through SIP (session initiation protocol), a method that has its pros and cons. You can use H.323. You can opt for WebRTC technologies that permit in-browser conferencing. This too has its pros and cons.

This is how conferencing works through SIP

    • You must have appropriate hardware (camera, microphone, speakers, computer systems) plus SIP gateways/servers in the background.
    • SIP in the software initiates sessions. These can be between two VoIP endpoints as well as include the PSTN line.
    • Video conferencing may be one way or two way or multiway. Single way connection allows you to broadcast messages. Duplex allows interactive conferencing with both parties able to see and talk with each other. Others may join in through an authentication sequence.
    • It must be noted that SIP simply manages the establishment and termination of connections. Transport layer such as TCP, UDP, or SCT and hardware take care of credentials.
    • SIP-based video conferencing also permits users to send data and exchange documents during an ongoing session. It can also allow interoperability with older H.323 based video conferencing.
    • Once a session is established the software combines audio and video inputs and converts them into digital data and further compresses data using codecs to reduce bandwidth usage. The packets have headers and travel across the internet to the destination and are assembled in sequence to reproduce the stream on the device.
    • There are further layers of refinements such as using SVC codec for clarity of audio and to reduce jitter in the video as well as encryption to ensure data is secured. One of the most common codecs in use is H.264 for high-quality audio-video.

This is just touching the surface. Video conferencing could be a point to point or multipoint. In the latter case, you could have centralized multi-point video conferencing or decentralized multipoint video conferencing.

What can you do with it for business?
