Making Every (Milli) Second Count: Reduced Latency for Improved Audio & Video Experience

Making Every (Milli) Second Count: Reduced Latency for Improved Audio & Video Experience

Online education has found many takers owing to its ease of delivery, reach and flexibility. In many situations, it is being looked upon as a viable substitute for conventional education, allowing for a lifelike teaching and learning environment in a virtual classroom.

The audio and video communication in a virtual classroom is a key feature that makes online teaching and learning engaging, real, and compelling. To maintain the quality of this experience, state-of-the-art IT infrastructure is needed, which can seamlessly deliver information to individuals across geographies in an agile and consistent manner.

Audio and Video Experience: Agility Matters

The quality of audio and video communication depends on, among other things, the agility of the IT network. In simpler words, it is about how fast information can travel in the form of packets of data from the point of origin to destination over a network. The idea is to keep the latency to a minimum while this happens.

Latency is the time delay that occurs when data travels from a source to destination.  There are various causes of latency, including analog-to-digital conversion, buffering, digital signal processing, queuing, transmission time, and digital-to-analog conversion.

To understand the concept of latency in a better way, you can imagine yourself standing on a hill and calling out to your friend in the valley at the bottom of the hill. Even if you are loud enough, there will be some delay before your friend can hear your voice.  This delay is latency.

When it comes to audio and video communication using an IT network, packets of data containing digitized audio and video signals travel a long distance over a data network with several gateways before they are received by the user.  A long delay in receiving the data adversely affects the user experience in terms of audio and video delays.

Reining in the Latency: The WizIQ Solution

At WizIQ, we continuously strive to raise the bar for ourselves and enhance user experience in the Virtual Classroom.  To this end, we recently added a few more servers to our IT ecosystem, thereby making our technology infrastructure more robust than before. With this addition, WizIQ now has servers in the US (Washington D.C., California, and Texas), Ireland, Sao Paulo, Singapore, Tokyo, and Sydney (see Figure 1.1). These multiple servers allow us to provide best-in-class services to our users in every part of the world.

In addition, we have improved the manner in which data is transmitted between users by adopting the shortest possible route for data transfer. These changes have considerably reduced the data transmission time, resulting in lower latency and better audio and video communication and screen sharing in the Virtual Classroom. WizIQ is committed to continuously improving its services with a steady and sizable investment in IT infrastructure.

User Experience takes Center Stage

While all the above-mentioned technical improvements sound great, the litmus test of the enhancements lies in the improved user experience which takes center stage at WizIQ. We hope you will find the overall experience of using the WizIQ Virtual Classroom more satisfying now.

If you have any questions about the upgrade, or wish to share your feedback, write to us at support@wiziq.com.
