castLabs has announced a Common Media Application Format (CMAF)-compliant solution designed for low end-to-end latency video playback with Broadpeak. The solution is intended to reduce transmission time to less than a second for use cases around interactive TV and live sports.

The combined solution uses castLabs' PRESTOplay video player SDKs, Broadpeak's nanoCDN technologies, and a choice of live encoding service to reduce latency at all stages of the content streaming workflow.

At the packaging level, CMAF combined with chunked transfer encoding (CTE) enables encoding of small chunks that can be processed on-the-go before they are finished downloading.

At the CDN level, Broadpeak's nanoCDN multicast ABR technology is designed to reduce jitter and remove the need for high amounts of buffering on player side that cause playback delays.

At the player level, PRESTOplay video player SDKs take CMAF content encoded into smaller chunks and can play them sooner.

"This easy-to-deploy joint solution allows streaming service providers to minimize end-to-end latency while preserving video quality and benefiting from fully featured player applications for all screens," said Michael Stattmann, CEO at castLabs.

"Decreasing latency is mandatory in our video delivery systems that play along with very reactive social medias," said Jacques Le Mancq, CEO at Broadpeak. "But this cannot be done at the expense of the quality of experience. Broadpeak nanoCDN multicast ABR solution creates the network conditions that allow castLabs player to perform at its best - with high quality combined with low latency."

The combined solution will be shown at IBC2018 in Amsterdam in September.
