Enabling Your Broadcast-Quality HDTV Experience With ZiXi

ZiXi enables the marketability of brand new HDTV, 3D and multimedia delivery, viewing, communications and interactivity globally over the Internet for broadcasters, business users, organizations and consumers.

For live and on-demand HDTV, 3D and multimedia delivery and collaboration, the ZiXi Video Transport Platform delivers outstanding performance (only a split-second latency), superior reliability (near-zero packet loss) and the highest video quality (at the physical end-to-end bandwidth available and up to 1080p/60fps) all at the same time with no tradeoffs to delay, resolution and stutter. In spite of the varying and nondeterministic network conditions of the public Internet — where the amount of network errors, packet loss, jitter and out-of-order packets fluctuate every second — ZiXi's proven and patented technology dynamically resolves the issues in sub-millisecond response time to deliver pristine, uninterrupted and very low latency video. With minimum overhead to physical bandwidth, this dynamic mechanism provides low end-to-end latency, removes jitter, recovers and re-orders packets, smoothens video flow and regenerates video in its original form, all in real-time and before it's time to play every frame of the video. ZiXi's superior multimedia transport technology resides at the source and destination of delivery (in ZiXi Feeder and Receiver™), as well as in the cloud (ZiXi Broadcaster™ in the Internet video network, or the broadcast, distribution or content delivery network). Latency is kept to a minimum with a guarantee of a maximum of 500ms over any distance. ZiXi also guarantees zero packet loss, even in networks that are failing at the rate of more than 30%! Finally, ZiXi ensures no overhead to maximize use of the available physical bandwidth end-to-end.

Other solutions (Forward Error Correction (FEC) and Scalable Video Coding (SVC)), add excessive overhead (30% or more!) to the available bandwidth for video. This overhead further limits the already constrained links between nodes and uses up bandwidth that could have been used to improve video quality. Furthermore, such alternative video transport methods can provide low latency but cannot guarantee recovery from packet loss due to the unpredictable behavior of the network and the statistical nature of their packet recovery mechanism. To overcome these limitations, these alternative solutions require the source and destination ends of video delivery to reside in network locations that are behaving in good condition, which increases costs, reduces security and protection, and limits deployment flexibility. The ZiXi solution is superior to these alternative approaches by dynamically adjusting and consistently optimizing the end-to-end experiences of video reporting, collaboration, broadcast and distribution. Users will experience no startup delay, no buffering or pauses, and no lowering of video resolution. Furthermore, the ZiXi technology, with up to 256-bit AES security, may reside entirely in the customer's premises to offer the highest levels of performance, reliability, security and quality over the public Internet.

ZiXi has introduced a new multimedia transport platform that is based on RTSP framework and leverages the efficiencies of the standard UDP over IP protocol. ZiXi has optimized the end-to-end video source to destination experience with no startup delay, no buffering or pauses, no lowering of video resolution and ensuring the highest degrees of security. ZiXi enables customers to retain their existing encoded content formats, existing HTTP/ HTTPS/ RTMP/RTSP streams, existing front-end applications, and existing business-process workflow, minimizing impact and changes to their existing infrastructure, applications and operations. ZiXi enables flawless, broadcast-quality multimedia transport service end-to-end over the Internet, connecting content sources to intermediaries, and intermediaries to end users. The result is a flexible HD multimedia transport service suitable for supporting a wide range of video/multimedia delivery needs and applications.
