VideoFlow DVP enables Italian broadcaster to cut satellite backup

August 18, 2014 // By Jean-Pierre Joosting
Teleradio Padre Pio, an Italian broadcaster, is now using VideoFlow's Digital Video Protection (DVP) technology to replace the expensive satellite backup that it had been using for its fibre connection.

DVP enabled the transport of high quality, live content over the Internet so that annual connection costs are around a tenth of using a satellite connection. The one-off capital costs are low providing an ROI of only a few months.

Live video broadcast are sent as a continuous bit stream, which the Internet was never designed to handle, resulting in artefacts caused by jitter, and packet loss. More than a couple of seconds of latency is unacceptable by customers expecting to enjoy the excitement of live events like sport as they happen. VideoFlow's patent pending technology opens the Internet for delivering content by ensuring that no packet is lost and nullifying the jitter caused by transiting the Internet.

The DVP comes as a "Plug and Play" pair - a Protector, which stores the packets until it is certain that they have been correctly received, and a Sentinel which monitors the health of the video stream by watching for packet loss and requests packets to be resent from the Protector's cache only if required. This is ensured by the company's patents, which cover techniques to minimize the number of packets that have to be resent.
