The world is now awash with affordable bandwidth. Video delivery over IP is rapidly overtaking Satellite and Microwave. Pretty soon many inanimate objects and appliances will have their own IP addresses. The only problem is that the Ethernet/internet protocol was not designed with video packets in mind. The issue is that video packets must arrive at their destination within a set time otherwise they "expire" like spoiled food and are discarded. The other issue with video is that the UDP protocol does not do well with traffic congestion.

ARQ based DOZER is a proven packet loss correction technology that enables reliable delivery of UDP traffic across WANs and LANs. It corrects for packet loss, fixes jitter, and encrypts your traffic with AES 128. It is interesting that low level of packet loss can be found even across dedicated TELCO lines due to TCP packet contention. DVEO's DOZER operates at layer II of the OSI stack. This makes our technology more resilient and suitable for video and VoIP over wired or wireless links.

The DOZER Rack is designed for compressed video but accepts almost any bitstream with any protocol, with any kind of content. A growing list of customers are using it to transfer VoIP traffic, and others use it to send uncompressed (SMPTE 292) or lightly compressed digital video (NewTek™ NDI®) across public or private networks and LANs. The DOZER technology can be adapted for any kind of “bit” delivery task as long as there is a twoway connection.

We all know that the Public Internet has improved dramatically all over the world, but especially in the Western World. We have all become voracious consumers of bandwidth by using video sites like YouTube, Hulu, CNN, and other streaming services. The Internet has largely kept up. But like in any jungle, there are thin and thick areas to penetrate through. When the jungle gets thick the traffic slows down.

Despite the abundant bandwidth, mission critical video traffic has been relegated to dedicated lines, services, or CDNs. This is because of fear, uncertainty, and doubt. Our engineers recently developed a “technique” that allows video traffic to consistently bulldoze through slow and congested routers when UDP protocol is employed. Basically – we send a minimal set of unique signaling packets along with original packets. In the interest of security we encrypt all traffic with AES128.

The DOZER ARQ: LIC “bulldozes” through routers and enables IPTV operators and Over The Top video providers to improve their video distribution by enabling smooth low delay High Definition and Adaptive video streaming. It's the ideal technology for CDN operators or mobile network operators who are deploying vast networks across their own and others' backbones. The DOZER ARQ: LIC optimizes IP capacity utilization by managing and optimizing video packet throughput.

RELIABLE LIVE MEDIA OVER IP


     

Tiny (5.5 in square), real time, quick starting, embedded Linux® based, remotely manageable, SD or HD, H.264 or H.265 video and audio decoder for receiving live DOZER streams from some DOZER enabled sources. This end point is designed as an enhanced set top box with ability to receive the "DOZERIZED" streams and decode the compressed stream into uncompressed HDMI. Supports H.264 at .1 to 15 Mbps. Ideal End Point for delivering content over great distances reliably and inexpensively. Supports RIST protocol.

Windows® based live streaming accelerator to alleviate packet loss and jitter between two Windows® 7 or 10 based computers. Completely transparent to any streaming application since it relies on OSI Layer II handshaking between the two devices. Install it and forget it. Ideal application for live video transfers across long distances. Designed for professionals who need reliable communication across long distances over congested internet.

Easy to implement (ARQ) error correction and AES encrypted point to multipoint content distribution service based on DVEO DOZER™.  This is a build-your-own network you set up by purchasing licenses from us.  You do not buy any hardware (CAPEX) and do not maintain the hardware (OPEX).  You set up your own cloud or you set up the licenses on Amazon Elastic Cloud or Azure Cloud.  Target customers want to deliver content from their local source to overseas affiliates and expect significant packet loss and also desire AES128 security.  Savings come in CAPEX and OPEX since there are minimal up front expenses and very low manpower is needed.

Forward Error Correction (FEC) is a method for finding and correcting bit and low packet loss errors in data transmissions. Extra data, called multi row and multi column checksum packets, are transmitted in parallel to the outgoing video stream so that errors can be corrected at the receiving end. The original UDP stream is not modified in any way.

The FEC Box IP IP reduces packet loss over a lossy network transport by mathematically reconstructing the missing data packets using the added FEC data.

The FEC Box IP IP is a very small, DC brick powered, computing device with two 10/100 Ethernet jacks. The purpose of the device is to ensure UDP traffic reaches the destination even when errors occur during transmission.

Compact (5.5 Inches Square), Real Time, End to End FEC SMPTE 2022 Error Correcting Router for UDP Traffic. Corrects Bit Errors and Packet Loss which Impacts UDP (and RTP) Traffic on both LAN and WAN Communications. Features Bit Rates of 25 Kbps to 120 Mbps. Commonly Used to Fix or Protect Against Frame Loss, Picture Artifacts, Audio Drop-Out and Other Video Decoding Errors Caused by Packet Loss. Unlike TCP-IP Retry Solutions, FEC Does Not Increase Jitter and Only Minimally Increases Latency. Sold in Pairs. Adds FEC to Encoders or Decoders that Do Not Support It.

Compact (1 RU), Real Time, End to End FEC SMPTE 2022 Error Correcting Router for UDP Traffic.
