Broadpeak Highlights Low Latency Streaming and CDN Efficiency at IBC 2017

French vendor of CDN (Content Distribution Network) and video delivery technology Broadpeak will show off enhancements for low latency streaming and bandwidth saving at IBC 2017. The focus will be on combining quality of experience with cost effective delivery to online devices for both traditional operators and pure play OTT services.

The company is aiming to capitalize on its nanoCDN technology, which extends multicast CDN delivery to end devices in the home by recruiting CPE equipment including Set Top Boxes, broadband gateways, routers and cable modems as end nodes of a CDN network. In this way when multiple devices are consuming the same channel in the home it only has to be delivered as a single stream over the access network to the premise.

Broadpeak will be demonstrating its Multicast ABR (Adaptive Bit Rate) technology for nanoCDN, which has already been deployed by various operators including IPTV and OTT service providers, even if the company has struggled to attract the highest profile names. The main appeal of nanoCDN lies in helping operators cost-effectively manage consumption peaks for live multiscreen services when multiple users per home consume popular services. At IBC 2017 Broadpeak will be highlighting new use cases for nanoCDN, including very low latency for live video streaming, which is becoming essential for OTT to compete with broadcast services. Broadpeak is now offering a version of nanoCDN to satellite operators for delivery of both live and on-demand services to connected devices such as tablets, smartphones and smart TVs.

Broadpeak is also targeting cloud PVR where the main appeal for consumers is the ability to record from multiple channels simultaneously without being limited by either available access bandwidth or the number of tuners they have. Broadpeak claims to support all Cloud PVR functions, including start-over, time-shift, and catch-up TV, as well as impulsive recording, via either a shared copy or private copy model. Under shared copy the operator only has to store one copy of each piece of content irrespective of how many users elect to record it on their cloud PVR service, just pointing users to the relevant storage location when they want to play it. But this is still prohibited in some countries, which requires the much less efficient private copy model where a separate copy is stored for each use. Either way, the recorded content can be processed on the fly to be viewed on any device type.

Operators would like to migrate from legacy IPTV or digital broadcast live streams to all Adaptive Bit Rate, according to Broadpeak CEO Jacques Le Mancq.

Broadpeak will be showing its other flagship product, its umbrellaCDN, which allows content providers to select the best CDNs for delivering video content at a given time according to availability, cost, latency and other factors. At IBC 2017, Broadpeak will highlight CDN Diversity, a new function of umbrellaCDN, which allows content providers dynamically to take account of the varying quality of several CDNs under a single service. It can then combine their contributions and deliver the content at a higher level than would be achievable with the best CDN alone.

On the same theme of maximizing QoE while saving costs, Broadpeak will demonstrate BroadCache Box, a local video caching product for broadcasters and content aggregators. The company claims this significantly reduces CDN costs while boosting subscribers' QoE. The idea is that local caches close to subscribers are deployed in telecom or cable operators' networks where the most popular content from a specific content provider is stored. Since the content is streamed from a location closer to end-users, latency and network congestion are reduced, resulting in higher video bitrates, faster start times, and less chance of a viewing session being interrupted. Broadpeak argues that as the most popular content can represent more than 80 percent of video traffic, caching at the ISP level significantly lowers CDN service costs.

But perhaps the most compelling aspect of the company’s offering lies in potential for converging legacy and online services around a common video delivery platform at the access level. “In an ideal world, pay TV operators would transition from legacy IPTV or digital broadcast live streams on STBs to all-ABR, with the benefit of having a single implementation to address all devices,” said Broadpeak CEO Jacques Le Mancq. “Until nanoCDN, two challenges stood in the way: lack of scalability for managing live TV peaks and latency issues during live streaming. NanoCDN solves both issues, in a secure manner. We believe that multicast ABR technology is the missing piece to implementing a fully converged video delivery architecture that is the future of television.”
