Media content today is increasingly streamed video, and this trend will only grow as the speed of consumer internet and video quality improve. Traditional video streaming platforms, such as Netflix and Hulu, now account for only a portion of this content as more and more live events are streamed over the internet. And consumer-generated content on video-based social networks such as Twitch and TikTok is now more accessible and gaining popularity.
This report focuses on the current state of video delivery, including the challenges content providers face and the various solutions they're pursuing. The findings in this report are based on a recent survey conducted by Edgecast, a content delivery network (CDN) that helps companies accelerate and deliver static and dynamic content to end users around the world.
The video delivery market is segmented into two parts: live and on-demand video streaming. On-demand video is video content that has been produced and transcoded in its entirety prior to delivery, and it may be watched or rewatched at any point in time. Movies and television programs are good examples of on-demand video streams. Live video streaming comes direct from a source, transcoded and delivered to consumers in real time. A good example of live video streaming is a sporting event. Currently, the emerging video streaming protocols, Apple HTTP Live Streaming (HLS) and MPEG-Dynamic Adaptive Streaming over HTTP (MPEG-DASH), follow a similar delivery premise. Small segments of the video are downloaded via HTTP(S). The use of HTTP(S) enables us to take advantage of HTTP/2 and content delivery networks for optimization. While Real-Time Messaging Protocol (RTMP) is still used and can be tunneled over HTTP(S), it will not be the focus of this report.
