Video over internet erstatter kostbar satellit-backup

Den italienske broadcaster Teleradio Padre Pio har med stor succes og markant kostreduktion implementeret firmaet VideoFlow's såkaldt Digital Video Protection (DVP) teknologi (in english).

Nicola Palazzo, Managing Director at PSE, an Italian system integrator, explaines:
-We maintain and service the uplink and distribution system for Teleradio Padre Pio and, as part of that contract, we are always looking for ways to improve and reduce costs. Over the past year, we have been working closely with VideoFlow's Italian distributor, Diem Technologies, to test and evaluation how effective and robust VideoFlow's technology is in a variety of real world conditions where the quality of the network connection can vary.

It passed every test we put the VideoFlow solution through delivering robust, stable high quality video by accurately correcting for packet losses and eliminating packet jitter during transit over the Internet. This gave us the confidence to recommend replacing the satellite-based backup with the VideoFlow over Internet solution. A 24x7 service demands reliable backup hence you have to know that the backup will work every time! 

Teleradio Padre Pio broadcasts to over two million followers in the EU. Content such as coverage of celebrations, festivals, special events etc., is generated in the company's studios in San Giovanni Rotondo in Southern Italy and then sent to Telespazio dish farm in Avezzano some 500 km to the West where it is sent onto a satellite for distribution across Europe. The connection between San Giovanni Rotondo and Avezzano uses a dedicated fibre connection that is now backed up by VideoFlow's solution. This uses a pair of VideoFlow DVP10s linked by a 2MB/s Internet connection.

Padre Mariano Di Vito, President of Teleradio Padre Pio, commented that the links were costing them a fortune and that Teleradio Padre PIO is constantly looking at optimizing the operational costs hence looking for a solution that will reduce the cost of video delivery without compromising the quality of the service.

Eran Shalev, VideoFlow's VP of Marketing, explaines:
-  The real proof came when the main fibre connection went down a couple of times for several hours and the VideoFlow connection took over without any break in transmission or change of quality. The high confidence in the VideoFlow technology means that Teleradio Padre Pio is now considering replacing the main connection with a VideoFlow solution for even more savings as well as using VideoFlow technology to protect the quality of an Internet connection between San Giovanni Rotondo and EWTN, a global catholic network, in Irondale, Alabama, USA. 

Mrs. Ronit Kalujny, VideoFlow's CEO, adds:
- Teleradio Padre Pio is our latest addition to VideoFlow's growing religious broadcasting vertical. The eco system of the religious broadcasting is changing with the ability to now utilise unreliable networks as a reliable transport for delivering broadcast quality video and reach new audiences and followers. Our DVP product line delivers high quality, live content over unreliable, unmanaged networks, including the Internet, making it a reliable communication channel for broadcasters at a fraction of the costs of current legacy systems. As our installed customer base continue to grow, it becomes easier and easier for prospective customers to see for themselves how reliable and effective our solution is. Seeing is believing. 

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.
