Building optimized systems that scale to meet peak demand delivers broadcast facilities that are orders of magnitude more efficient than their static predecessors. In part 2 of this series, we investigate how this can be achieved.
For many years broadcasters have been working with static systems that are difficult to change and upgrade. This two part series explores the unfolding of a more elastic future based on COTS hardware and flexible licensing.
One of the earliest and most widespread applications of synchronizing was in television.
Part 1 of this series described how network-side QoE (Quality of Experience) measurement is fundamental to proactively assuring the quality of OTT services. At its core, the network-side can be an early warning system for QoS, which in turn correlates to actual QoE performance. This article considers the two types of network monitoring available to us, relative priorities for the points of measurement, and how the video platforms contributing to OTT services are evolving to support OTT quality at scale.
Broadcasting video and audio has rapidly developed from the send-and-forget type transmission to the full duplex OTT and VOD models in recent years. The inherent bi-directional capabilities of IP networks have provided viewers with a whole load of new interactive viewing possibilities.
Synchronizing became extremely important with the growth of AC power systems, which ended up being used to synchronize all sorts of equipment, from Radar to television.
