Streaming playback and dynamic ad insertion

摘要

There is provided a system and method for dynamically generated client side streaming playlists. There is provided a method comprising receiving a request to stream a video asset for playback, retrieving, from a network, a video asset playlist corresponding to the video asset and an ad campaign playlist, generating a consolidated video playlist including the video asset playlist and the ad campaign playlist, and processing the consolidated video playlist using a media playback framework to stream a plurality of video files from the network for decoding and output to a display. Discontinuity tags within the video asset playlist may be utilized as insertion points for portions of the ad campaign playlist. The consolidated video playlist may be accessed through a local HTTP web server, advantageously allowing the use of commonly installed media playback framework models such as QuickTime X to trigger adaptive bitrate support through HTTP Live Streaming.
