Dynamic ad-insertion and content orchestration workflows through manifest manipulation in HLS and MPEG-DASH

The described proof-of-concept demonstrates, how manifest manipulation enables dynamic ad insertion and flexible over-the-top streaming workflows including ondemand-to-live services across a multitude of devices and platforms via MPEG-DASH, HLS and hybrid TV environments like HbbTV. Content manipulation and dynamic ad insertion is realized through non-video-intrusive technologies operating on manifest level in a highly flexible and scalable system architecture. APIs allow for individual stream management and channel orchestration. Dynamic digital video contents and advertising can be integrated per user and on the fly, in both linear and ondemand content. The evaluated system incorporates recent content stitching and content insertion techniques as DASH events, Xlink, SCTE35 and manifest rewriting for on demand and live sources. The different technologies have been evaluated against state-of-the art HLS and MPEG-DASH video players in multiscreen environments to derive best practices for short term utilization. In addition, recommendations for content creation and player implementations have been evaluated to further support the integration of those technologies in future solutions.
