As online streaming video grows in popularity, increasing audience sizes will put more demands on network operators and content distributors. Massive live events and popular VOD content will require more capacity, better resiliency, and heightened operations. This content may also require potentially different delivery approaches (IP Multicast, UDP vs. TCP, and LTE broadcast) to provide the Quality of Experience (QoE) that viewers want. And such scaling must happen transparently, leveraging resources behind the scenes in a cost-effective manner. In this working group, participating members focus on solving the challenges of the best broadcast approach, event planning, and implementation of the scale required to support rapidly increasing audience sizes.
