Wowza Cuts Latency of Cloud Streaming Service

Wowza Media Systems has updated its cloud streaming service to reduce latency for Apple HTTP Live Streaming (HLS) workflows and also offered trial users access to a development testing environment to work with Wowza APIs and SDKs. Developers can now integrate directly with the Wowza Player.

Like other streaming technology vendors Wowza is responding to pressure for lower latency driven by the proliferation of OTT, especially live services which are less tolerant of delay. Despite the growth of the open MPEG DASH, HLS remains one of the most prevalent standards for HTTP streaming in OTT environments, working by breaking the audio/video streams into sequences of small HTTP-based file downloads, each comprising one chunk lasting typically multiples of one second. Microsoft’s Smooth Streaming and Adobe HTTP Dynamic Streaming are the other two principle streaming technologies, although these have been converging towards DASH more than HLS. All four though follow the same principle of segmenting video into manageable chunks to allow for varying network bandwidth and end user device capability. HLS is still widespread because it runs in just about all Apple connected devices.

Wowza says it can now preconfigure HLS streams to reduce latency to 15 seconds, well below the HLS average of 30 to 45 seconds. It has also adopted new options for managing the sizes of chunks nimbly on the fly so that operators can fine-tune the settings to achieve the optimal balance between video quality and latency.

"Wowza Streaming Cloud is now the ultimate solution for HLS live-streaming when speed is critical, with easy-to-use presets that reduce latency and eliminate the need for difficult configuration," said David Stubenvoll, CEO and co-founder of Wowza Media Systems.

Wowza Streaming Cloud API Sandbox is now available as a testing environment for developers to build and test REST (Representational State Transfer) API calls. This test area directly within Wowza Streaming Cloud gives developers the ability to rapidly deploy, test and make changes, without incurring usage charges or impacting production workflows. In addition Wowza has updated its set of code samples and development documentation to help rapidly deploy streaming applications.
