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.
