Streaming Improvements: Low Latency and Multiview

Low latency wireless broadcast production over 5G  - $15

Wireless camera feeds are an integral source of content for programme making, and typically utilize licensed point-to-point radio links or “bonded-cellular” devices. Cellular bonding using public 4G and 5G networks has become a mainstay for electronic newsgathering and remote contribution feeds. These contributions can tolerate latencies up to several seconds. However, such latencies are far too long for broadcast production, where wireless cameras are cut in with cabled systems, or where remote camera control, tally and return video are required. Since 5G is a native IP technology, it can support bi-directional connectivity and facilitate additional services alongside ultra-low latency video. This paper explores the use of (private) 5G to support full low-latency wireless production workflows, discusses how 5G connectivity can augment existing wireless systems, and gives practical advice for configuring camera control systems over 5G.

Solving the Multiview Problem - $15

As streaming services evolve, viewer demand for new and innovative ways to consume content is making multiview an essential feature. There are several ways to provide multiview experiences on end-user devices including encoding composite feeds in desired permutations (“Many Encodes”), spawning multiple independent players on the user device (“Many Players”), or using cloud encoding. These approaches that are currently used in the market all have downsides.

Single-Player Multiview, an alternative to these approaches, is flexible, responsive and scalable. With full knowledge of everything that is happening on the screen and the network combined in a single player, that player can adapt its adaptive bitrate (ABR) decisions and segment retrieval strategy accordingly. Single-Player Multiview is also the only approach that can ensure reliable sync between multiple feeds.
