VideoFlow enhances video protection performance with the DVP100X

Large flexible networks can now be created more cost effectively to deliver error-free, live, high quality video over unmanaged networksIBC 2014 booth B20 in Hall 3

Rosh Ha’ayin, Israel — 21 August 2014 – VideoFlow will be launching an important addition to its range of Digital Video Protection (DVP) solutions for delivering live, high quality video (SD, HD and above) over unmanaged, best efforts networks.

VideoFlow DVP100x

The new DVP100X handles up to 80 streams and 80 virtual private network (VPN) tunnels simultaneously reaching 300 Mbps.  This means that large multi-point networks can be created cost effectively using VideoFlow’s technology which enables live content to be delivered over unmanaged networks like the Internet with no packet lost and nullifies the jitter caused by transiting the Internet.  The DVP100X provides broadcasters, teleports and operators a highly advanced, cost effective solution for broadcast quality, live video over standard Internet connections thereby eliminating the need for expensive service level agreement (SLA).  In addition, the DVP100X offers secured video connections with IPsec for maximum security level.  VideoFlow’s products offer one time capital costs, with very rapid ROI’s, in place of never-ending and ever-increasing operational costs.

There are three versions available.  The DVP100X Protector, which stores the packets in the case a packet retransmission, is needed.  The DVP100X Sentinel eliminates the jitter by locking to the video stream, monitors the health of the video stream and requests packets to be resent from the Protector only if required.  The DVP100 Fortress for the transit network which acts as Protector and Sentinel in the same time hence allow isolating the distribution network from the contribution network further reducing the cost of delivery by decreasing the required uplink bit rate for a point-to-multipoint delivery as well as the additional overhead for packet recovery.
Mrs. Ronit Kalujny, VideoFlow’s CEO, explained, “All our DVP products can be used in a mix and match manner.  For example, several DVP100X Protectors can feed into one DVP1000 to gather content from many different locations.  Similarly, one DVP100X Protector can distribute content to numerous DVP10X or DVP100 Sentinels.  The DVP100X is designed to meet our customers’ need for more cost effective, large network configurations.”
Mr. Adi Rozenberg, VideoFlow’s CTO, stated, “Our customers are very happy with how rock solid our live video and audio streams are going over the standard Internet. They immediately realize that VideoFlow’s DVP enables them to achieve exceptional quality coupled with considerable savings unlike existing solutions.  The DVP100X enables the creation of large scale networks cost effectively and the flexibility to adjust them as needs change.  In addition IPsec has become an important requirement for our customers.  The DVP100X enables supporting IPsec in high capacity networks.”

VideoFlow technology

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.  By doing so, it affords broadcasters, teleports and operators the opportunity to use a highly advanced, low cost solution for live, high quality video streams in place of existing, expensive solutions.

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 VideoFlow’s patents, which cover techniques to minimize the number of packets that have to be resent.  VideoFlow’s solution is highly flexible working with internet connections as slow as 200Kb/s or as fast as 800Mbps yet delivering the desired high quality.  VideoFlow’s patents also covers techniques to reduce bandwidth overhead to the minimum possible and to keep any delays at less than the two seconds, which is the maximum tolerated for true live broadcasts.  VideoFlow’s DVP family of products enables the reduction of bandwidth requirements cutting operational costs compared to the current solutions.

VideoFlow is the pioneer of live high quality video (SD, HD and above) over standard internet connections.  Its DVP (Digital Video Protection) solutions rapidly pay for themselves by making expensive leased lines redundant for live broadcast.  The high quality of the original high quality video input is maintained during its transfer over the internet without artefacts, jitter or latency greater than two seconds.  VideoFlow has four key technology patents covering Live Content Delivery Networking (LCDN) with over a dozen patents pending.
