When it comes to video technology, “cloud computing” remains a popular industry buzzword even though the term began trending well over a decade ago. Over the years, having a cloud-enabled or cloud-native platform meant your software could support the future. It was flexible enough to run on different hardware platforms and in different environments. It was elastic, so it could scale based on demand and it could be more easily managed using standardized tool sets. These days, almost every video solution provider offers cloud capable technology and yet, cloud remains a top marketing term despite that fact. Why is that?

Reducing latency for live video streams delivered using HTTP adaptive bit rate (ABR) technology has become a top priority for service providers that are seeking to deliver a better multi-screen viewing experience to consumers. Latency is characterized as the delay between the time an event actually occurs (real-time) and the time the event is viewed by a consumer on their screen. With legacy broadcast TV signals, latency is approximately 5 seconds. With the introduction of traditional IPTV services a decade ago, latency rose to around 10 seconds. Today’s over-the-top (OTT) implementations of HTTP ABR technology can exhibit latency of 30 seconds or more for live content. Latency reduction requires a holistic approach to identifying and addressing sources of delay within the video streaming workflow. With the right approach, service providers can reduce latency for OTT streams to broadcast levels or better.
