Based on MPEG2-TS, HLS (HTTP Live Streaming) is Apple’s patented streaming format. It is an adaptive streaming communication protocol. Initially, HLS was used only for Apple devices. Now it is supported by other devices like Android-based smartphones.
HLS works by splitting live streams into a sequence of smaller HTTP-based file downloads. Each download loading one small portion of an overall potentially unbounded transport stream. As the stream is played, the client may choose from several different alternate streams containing the same content encoded at a variety of data rates. This allows the streaming session to adjust to the available data rate. It downloads an extended M3U playlist at the beginning of the streaming session, which contains the metadata for the different sub-streams which are available. As an HTTP-based technology, no streaming server is required, so all the switching logic resides on the player.
HLS can distribute both on-demand and live video files. HLS uses the HTTP protocol. Hence, instead of using a specialized streaming server, users can stream media from their regular web server.

That’s because billions are being lost in live event revenue, such as sporting events, to pirates each year. But securing streaming content from theft isn’t an easy task. There are hundreds of possible vectors, everything from network intrusion to player/app doppelgangers to CDN leeching, through which pirates can obtain and redistribute content. In this webinar, SVTA CEO Jason Thibeault will take a look at some of the more prominent vectors, techniques and tips to mitigate potential problems, and discuss the recent SVTA Security Working Group publication, “OTT Streaming Security Checklist.”
