1. File-based OTT Streaming (VOD Content)

File-based OTT streaming refers to the delivery of encoded VOD content over the internet.

Before delivery, file-based contents are encoded and packaged as MPEG-DASH or HLS packages. These packages are then transferred to webservers for HTTP delivery to the end-users. HTTP-based streaming enables the delivery of audio and video content over HTTP from ordinary web servers. To provide better streaming performance, content services use Content Delivery Network (CDN) systems. The CDN distributes the content across multiple servers and locations worldwide, so when someone hits play, they’re getting it from the closest, most efficient point.
