Abstract

Wireless camera feeds are an integral source of content for programme making, and are typically done using 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. The use of private5G to support this contribution workflow has been well documented, such as the coronation of King Charles III. 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, networks are able to support bi-directional connectivity and facilitate these additional services alongside ultra-low latency video. This paper explores the use of (private) 5G to support full low-latency wireless production workflows, along with discussion on device connectivity, augmenting existing wireless systems, and practical advice for configuring camera control systems over 5G.
