As video use continues to skyrocket in businesses around the world, IT departments need to effectively manage the strain video can place on a network. Considerations include:
First, video CMSs often stream videos using chunked (stateless) delivery. This enables video content to work well with caching proxies that many organizations deploy across their WANs. For frequently accessed videos and simultaneously accessed live events, the ability to use a WAN’s caching framework can substantially reduce overall bandwidth consumption.
Video content management systems typically use adaptive bitrate streaming to serve live and on-demand content. With adaptive bitrate streaming, the video CMS detects a viewer’s bandwidth in real time and adjusts the video quality accordingly (see below for an illustration).
To do this, the video CMS uses an encoder (typically installed on the server) to take a single-bitrate video as input, and encode it to multiple bit rates. For viewers, this results in minimal buffering during playback, faster start time, and a good experience for both high- and low-bandwidth connections.
Adaptive bitrate streaming dynamically switches between video streams of different
quality during playback based on available bandwidth.
Most video CMSs offer deployment options that can offload a portion of video content from the corporate network.
This hybrid option would reduce the load on the internal network for external content and ensure high global availability through integration with enterprise content delivery networks (ECDNs) such as Kollective.
Finally, video content management systems can help existing corporate video conferences achieve greater scale while reducing the load on the network. Popular video conferencing solutions such as Zoom, BlueJeans, Skype For Business, and GoToWebinar reach scalability limits between 500 and 1500 participants.
By contrast, live webcasts delivered through a video CMS can viewed by tens of thousands of viewers simultaneously. Because most video conferencing participants are passive viewers, the video conferencing stream could be routed through a video CMS to reach the desired scale while taking advantage of adaptive bitrate streaming and other bandwidth management capabilities of the video CMS.
