IP networks have become the popular, low-cost choice for transporting data, voice and video content. IP communications were originally designed to ensure data integrity, where the criterion for success is complete delivery. If data packets arrive late or are lost, protocols such as TCP exist to resend them without a major impact on the user experience. When it comes to live video, however, completeness is not enough. Packets must be delivered reliably and on time in order to ensure uninterrupted, broadcast quality video. Unfortunately, the inherent nature of IP networks, characterized by packet jitter, packet loss, and link capacity fluctuations – makes them unreliable for professional live video broadcast.

VideoFlow’s Digital Video Protection (DVP) product is used by leading companies worldwide to boost the reliability of IP networks, including the public Internet, for professional live broadcast. DVP enables to confidently contribute and distribute live video over IP with unprecedented levels of service continuity, at a fraction of the cost of leased lines or satellite links. It accelerates ROI by reducing operational costs and enabling new revenue streams across a wide variety of markets.

VideoFlow offers the DVP in a variety of form factors and capacities. You can choose the right DVP for your needs and grow it as you need it by simply adding more capacity and features as you need them with no interruption to the service.

P2P_DVP_Net_DiagTwo DVPs will protect the quality of the video over any IP network connection including the public Internet. The DVP comes as a “Plug and Play” pair – a Protector at the source, which stores the packets until it is certain that they have been correctly received, and a Sentinel at the destination 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. Nine layers of protection are making VideoFlow’s DVP highly flexible working with any IP connection including the public Internet to deliver the level of quality expected by professionals when broadcasting live.
