Fix packet loss


Dozer Packet Loss Solution Fix  ip.tv  Linux

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 DOZERbox 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 two-way connection.

Linux® Based, Real Time, 1 RU, "DOZER™" Packet Recovery Enabled Stream Segmenter, Repackager, and/or Protocol Converter for Real Time Conversion of UDP Network Streams to Multicast, Unicast, or HLS Network Streams. HLS Streams are Segmented Using Adaptive Streaming Technology. Supports 80 Streams of 5 Mbps Each or any Combination of Bitrates up to 400 Mbps Aggregate. This is an Embedded Linux® Based Appliance that Boots Quickly with a Simple GUI Interface. All Settings are Remembered when Power Cycled. Ideal WAN Bridging Device for Intercepting Streams and Reflecting and Redirecting Streams to New Locations with Different Protocols and Wrappers like HLS or RTMP.

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.

Standard Features:

  • Converts UDP streams to multicast or unicast streams, or other direction
  • Designed to repackage or chunk raw H.264 transport streams to HLS. This is called segmentation.
  • Input and output format can be MPEG-2, H.264, or H.265 (No transcoding)

The Value Proposition for DOZER

Licensing Terms for “DOZER ARQ: LIC” for CDN's, OEMS, and Middleware Vendors

fix packet loss, HLS Booster™

 

linux  iptv  Intel Platinum Partner

It is agreed that driven high value traffic and the ensuing abundant revenues drive Internet Infrastructure Providers like Verizon, ATT, COX, Time Warner, etc., to continually improve their IP infrastructure. Thanks to Smart Phones, etc., Public Internet keeps Getting much Better in the world.

Sadly in most regions of the world Public Infrastructure is not reliable and drops video packets. (Not true for Japan, Singapore, etc.)

The issue is that public routers do not prioritize video traffic well enough. They were not designed to do that. It's always been an afterthought. We have test data to prove our performance claims.

The DOZERbox and DOZER ARQ: LIC route video through the public internet in a unique way.

The DOZER ARQ: LIC Technology Utilizes Enhanced UDP and manages and optimizes Video Packet Transits across the public internet by doing real time packet reordering on the receive side via proprietary techniques involving multiple tunnels carrying extra information.

By thoroughly understanding the IP stack, switch and router architecture, we have engineered a product that offers enhancements to video traffic over Public Internet:

  1. Packet Loss. Most circuits have some packet loss. We count and control the packets as they leave and arrive. We just manage the packet loss so the packets do not get lost and time out…
  2. “Lower than most” Latency: We “bulldoze” through the routers in a special way.
  3. Packet Jitter. Fiber Optic circuits and radio circuits cause packet jitter. We manage the jitter by time manipulating the packets.

DOZER ARQ: LIC like other similar applications is available for licensing... We are actively negotiating with several IP STB vendors who are embedding the "receive" module in their IP stack. We are also used by some smaller CDN's...

Licensee No 3. Delivers End to End Video Service between Teleports and Post Houses and TV Centers.
