Hybrid Content Generation Workflows: From MPEG-2 TS To Adaptive Streaming And ISO-BMFF (2015)

By Yasser Syed, PhD and Alex Giladi, Comcast/Technology & Product: VIDEO Architecture Group, InterDigital Communications, Inc.

A transformation is happening in the content network delivery systems of the cable / IPTV world, which is increasingly moving us from a traditional MPEG-2 TS [Transport Stream] push-based ecosystem, toward a pull-based unicast ecosystem. As this transformation is occurring, we still need to maintain a consistent service experience, including aspects such as linear programming, DVR, accessibility features, etc. An established set of mechanisms and operational procedures already exists, via the traditional MPEG-2 TS model. Rather than rebuilding these mechanisms and operational procedures again, a hybrid content generation workflow model can be utilized to convert these services. This paper examines how this conversion can occur, such that the source content & service data may originate, be conditioned, and processed in a traditional MPEG-2 TS environment – but ultimately delivered to the customer in one or more adaptive streaming formats.
