HTTP Live Streaming Wikipedia. HTTP Live Streaming also known as HLS is an HTTP based media streaming communications protocol implemented by Apple Inc. Quick. Time, Safari, OS X, and i. OS software. It resembles MPEG DASH in that it works by breaking the overall stream into a sequence of small HTTP based file downloads, each download loading one short chunk of an overall potentially unbounded transport stream. As the stream is played, the client may select from a number of different alternate streams containing the same material encoded at a variety of data rates, allowing the streaming session to adapt to the available data rate. At the start of the streaming session, HLS downloads an extended M3. U playlist containing the metadata for the various sub streams which are available. Since its requests use only standard HTTP transactions, HTTP Live Streaming can traverse any firewall or proxy server that lets through standard HTTP traffic, unlike UDP based protocols such as RTP. This also allows content to be offered from conventional HTTP servers as origin and delivered over widely available HTTP based content delivery networks. Dsp-Ax763 Manual'>Dsp-Ax763 Manual. HLS also specifies a standard encryption mechanism4 using AES and a method of secure key distribution using HTTPS with either a device specific realm login or HTTP cookie which together provide a simple DRM system. Later versions of the protocol also provide for trick mode fast forward and rewind and for integration of subtitles. Lynk has also added the AES scrambling and base 6. DRM content key with a 1. SWF applications together with a sequential initialization Vector for each chunk to its implementation of the standard. Apple has documented HTTP Live Streaming as an Internet Draft Individual Submission, the first stage in the process of publishing it as a Request for Comments RFC. As of December 2. RFC Independent Stream Editor ISE to publish the document as an informational non standard RFC outside of the IETF consensus process. August 2. RFC8. 21. ArchitectureeditHTTP Live Streaming uses a conventional web server to distribute audiovisual content and requires specific software to fit into the proper format transmission in real time.

Codify and encapsulate the input video flow in a proper format for the delivery. Then, it is prepared for distribution by segmenting it into different files. In the process of intake, the video is coded and segmented to generate video fragments and index file. Encoder codify video files in H. AAC, MP3, AC 3 or EC 3. This is encapsulated by MPEG 2 Transport Stream to carry it. Segmenter divides the MPEG 2 TS file into fragments of equal length, kept as. It also creates an index file that contains references of the fragmented files, saved as. Algorithm In C++ Sedgewick Pdf. Distributor. Formed by standard web Server, accepts requests from clients and delivers all the resources. Client. Request and download all the files and resources, assembling them so that they can be presented to the user as a continuous flow video. The client software downloads first the index file through a URL and then the several media files available. The playback software assembles the sequence to allow continued display to the user. FeatureseditHTTP Live Streaming provides mechanisms for players to adapt to unreliable network conditions without causing user visible playback stalling. For example, on an unreliable wireless network, HLS allows the player to use a lower quality video, thus reducing bandwidth usage. HLS videos can be made highly available by providing multiple servers for the same video, allowing the player to swap seamlessly if one of the servers fails. AdaptabilityeditTo enable a player to adapt to the bandwidth of the network, the original video is encoded in several distinct quality levels. The server serves an index, called a master playlist, of these encodings, called variant streams. The player can then choose between the variant streams during playback, changing back and forth seamlessly as network conditions change. AvailabilityeditThe master playlist can list duplicate variant streams that have the same level of quality but are hosted by different servers. This enables the player to swap to a different server for a given bitrate if one of the servers fails. This grants a degree of high availability to serving streams. This can be combined with adaptability by listing multiple variant streams for each distinct quality level. Using fragmented MP4editOn WWDC2. Apple announced9 the inclusion of byte range addressing for fragmented MP4 files, or f. MP4, allowing content to be played in HLS without the need to multiplex it into MPEG 2 Transport Stream. The industry considered this as a step towards compatibility between HLS and MPEG DASH. Server implementationseditAdobe Media Server supports HLS for i.
