1. tet 2 Parameters HTTP Live Streaming HTTP Live Streaming is a protocol designed to deliver live streaming content to clients on the Internet using a standard unmodified Web Server and the standard HTTP protocol as depicted below 46 Encoder MVN EN460 soc Web Server IPSTB IPSTB Location 1 Location 2 Location N The highlights of the protocol are e The encoder segments the bitstream into small files of similar duration at some suitable points e The encoder continuously uploads the files as they are created to a standard web server e Every time the encoder uploads a new file it also updates a special playlist file in the server which informs the clients of which segments are available e The encoder also takes care of deleting old files from the server e The clients can connect to the web server at will they download the playlist file and start playing the segments as they come e A standard unmodified web server can be used HTTP Live Streaming is supported in the MVN EN460 The content can be uploaded to an external server or served directly from the unit When uploading to an external server the configurable parameters are A license is required for this feature please contact ImmediaTV 47 Output Protocol HTTP Live Streaming hod Server Location Remote Local Transfer Protocol G FTP O SFTP Server Address 10 10 9 48 Username encoder Password
