Everyone is using video conferencing solutions nowadays. Businesses are using these solutions so that they can increase their capabilities. Industries like finance, healthcare, real estate, education or logistics, now everyone is using it. All these organizations are now realizing how important and effective a video conferencing software is to connect with others. These solutions enable you to exchange visual and audio information with your team members and other persons.
Basic requirement for attending a video conference is
- A Computer with webcam and microphone
- A Smart Phone
- Browser or Video Conferencing Application
End To End Network of Video Conferencing
If we look back in time, video calls used to be done between 2 to 4 people only. This limit has extended to 1000. There are so many software available that can connect you to 1000 of people at once in a video conference.
The Internet is the only thing that connects all these devices with one another to make the transaction of information.
All end of the video conferences have a key in software. Whenever one end sends video and audio information, the system encrypts every bit of information during this transmission. The receiving system will decrypt this information at the moment of reception. This encryption assures that your data is secure from the cyber attack on the network. This security gives you a private network where you can chat and share information safely.
Whenever these data are transmitted, it passes through some server box. This software is programmed to choose the closest and optimized server available to the user to create a strong network. These servers can be present around anywhere in the world. Some companies establish their server in their own country to prevent data from going outside their own country.
During the transmission, received data from video and audio is converted from analog to digital. This conversion is necessary for the transmission purpose. This analog to digital conversion is performed by the video conferencing software you are using.
As these signals are converted from analog to digital, they undergo the compression process. This compression is required in order to save the data and load on the Internet. This compression method converts all the information into small packets. These packets make traveling over the network faster and easier. For a real time communication channel, the compression ratio used is 100:1. The average compression rate comes between 13.1 to 17.1.
As the signal reaches its destination the software at the reception end decompresses the signal. Now every signal that was compressed during transmission is arranged back to normal from the data packets.
The Final Result:
These signals are now converted back to analog from the digital signal. It is not necessary that the software will deliver you crystal clear video and audio. To keep the audio and video in synchronization, video softwares takes some extra precautions like acoustic and echo cancelling. This removes the sound interference and overlapping of sound.
There are so many different video conferencing software that are available in the market that basically work on these simple principles. But there are some extra features that one need to learn about before choosing the right video conferencing solution for self. So that was all in how a video conferencing works.
