Understand VP8 Video Conferencing Bandwidth

The typical high-definition audio stream consumes about 40 Kbps of bandwidth. Now consider that a jump to low-resolution VP8 video conferencing more than quadruples that amount of data per second. Even more impressive is that HD video explodes the streaming requirement to a whopping 1,500 Kbps – greater than 37 times the amount of audio alone.

Interested in our new Video Calling feature, but worried about your internet connection’s capability? You’re in luck because most broadband internet connections will have the ability to transfer HD audio and low-resolution video without an issue. You might even be lucky enough to smoothly stream HD audio and video without a slowdown in the rest of your network.

Part of our job at VirtualPBX is helping you understand the manner in which video calls will take place on our network. We show a few figures below related to internet speed, so take a minute to perform a brief speed test to see how your connection measures up.

A Quick Note About Codecs

All audio and video information that passes through the internet requires the use of a codec, which is simply a computer program that encodes or decodes information. It allows two computers to communicate with one another by using a common language.

The common language our Video Calling service defaults to is VP8. This open-standards codec works in all major web browsers and is supported on many other hardware devices. It’s a great choice, therefore, to match well with testing desk phones and softphones as we prepare for the public launch of Video Calling.

We also support a few other similar codecs. It isn’t necessary that we dig into the details of these codecs and how they work. For most VirtualPBX Phone Plan users, it’s only necessary to know that these codecs help us work with a wide range of devices. You can begin a deeper dive into the VP8 codec with the Wikipedia articles linked here.

Video Conferencing Bandwidth Requirements

VP8 video conferencing bandwidth are the primary concern for video conferencing users. In short, people what to know if their internet will clearly and reliably handle video calls.

We have built our Video Calling feature to respond to the unique needs of all our customers. Some businesses will have more bandwidth to spare than others; this means they can consistently stream video at higher resolutions. However, a common internet connection does not bar you from participating in video. Video Calling will adapt to your needs as a user.

Video Resolution (VP8) Bandwidth
Required

Required (Simulcast)
HD Audio Only 40 kbps
Low-Res Video (240×180)
+ HD Audio
150 kbps 240 kbps
SD Video (640×480)
+ HD Audio

The table here shows the bandwidth requirements for various types of video resolutions that can be used with our Video Calling feature. Simulcast values may be required during conferences with many participants in order to accommodate their device capabilities.

You can compared the values here with the bandwidth shown in your speed test. How does your internet speed align with the values shown here?
