Broadpeak was demonstrating its nanoCDN technology at the OTT TV World Summit this week, outlining how the innovative solution can dramatically reduce bandwidth requirements and also reduce costs for streaming video. The use of multicast, rather than unicast, for the streaming is at the heart of the solution. Broadband service providers with multicast networks (like telcos where they have a classic IPTV footprint) can harness this approach.
A video stream is duplicated (multicast) within the local CDN and client software on the home gateway is then used to convert a multicast stream back to unicast. This means that once in the home, there is no change to how the video is delivered from the gateway to the various multi-screen devices, whether these are laptops, tablets or mobile phones.
