HaiVision partners with MASERGY to provide system integrators with network video solutions

January 17, 2008 | Chris Payatagool



HaiVision is the industry leader in providing high performance video encoding and decoding systems for interactive boardroom communications. MASERGY is the industry leader in providing video specific, absolute QoS IP network solutions globally. The formula for high performance video communications - a quantum step beyond traditional videoconferencing - includes the best codec systems and the most reliable QoS sensitive broadband network, combined with audio visual systems and room design expertise.


Interactive Streaming - Without relying on MCUs, or being hindered by quad-split sessions, interactive communication systems deliver the highest quality AV from one point to the other, free of transmission delays or poor picture quality associated with traditional videoconferencing systems.

Point-to-point sessions are simple, bi-directional provisioning of network video streams. Multi-point sessions are accommodated by mapping a source camera onto dedicated monitors at each receiving location - every participant is represented on his or her own display. Using IP unicast and multicast technology, the network is the AV router!!!

MASERGY_SLA.jpgHigh Quality Connections - MASERGY provides a premium grade of IP bandwidth specifically engineered to deliver consistent performance of real-time (low latency) video with true TV quality at all times and under all network conditions.

MASERGY easily accommodates dedicated and secure network connectivity for video systems with little or no impact on your company’s IT infrastructure. Alternatively, MASERGY can accommodate a company-wide convergence of voice, video, and data connectivity. In addition to providing the raw, extremely high quality bandwidth to video destinations, MASERGY provides world class monitoring of its global IP/MPLS network that assures continuous operations. MASERGY can also provide clients with advanced management and provisioning tools to best tune network performance and meet the needs of your business.

Getting Started - In order to address your next interactive video deployment, regardless of global location, you need to consider 1) room design and components, 2) network video components, and 3) network connectivity. To estimate the network charges, MASERGY (the network provider) simply requires the aggregate full duplex bandwidth required at each location (see reverse page for guidelines) and the phone numbers and zip codes of the endpoints. Typically, they can estimate the one-time setup and recurring monthly charges within 24 hours for “the NFL��? cities (major US metropolitan areas). HaiVision and MASERGY provide a simple form to initiate the estimate process or you can contact MASERGY directly.

Hai_Bandwidth.jpgBandwidth Basics - HaiVision's network video systems are optimized for extreme performance, and are based on either the MPEG-2 standard for video compression or the MPEG-4 AVC (also known as H.264) standard. Although the MPEG-4 AVC standard can increase bandwidth efficiency by as much as 60%, systems based on this standard are only now emerging - with 100% mission critical systems requiring the tried and true MPEG-2 format. The overall bandwidth required is a direct result of the required picture quality (resolution) and the scene texture and speed (action vs. talking heads). The required bandwidth per video stream must take into account the associated video bitrate, the audio bitrate, and an allocation for network overhead (~26%). Planning and testing for the client’s subject matter is essential. Furthermore, in such continuous presence systems (no quad split) each remote participant (i.e., their video stream) must be mapped to an individual boardroom monitor. The required total bandwidth is the maximum of inbound or outbound streams.


Example - In the diagram above, a client wishes to establish a 4 point system. Each location needs to see the 3 other locations - so 3 displays are required. Each location needs to be seen as well, so 1 camera is required. The codec configuration needed is a single encoder and 3 decoders, or what is sometimes referred to as a 1x3 system. HaiVision accommodates this with the hai1060, combining both encoder/decoder blades and dual-decoder blades (see lower diagram). The encoder blade can either multicast or "multiple-unicast" the camera to each of the 3 remote destinations. In both cases, the maximum of either inbound or outbound streams at each site is 3. If the video requirements indicate that a 2.7 Mbps video bitrate is appropriate per stream, and a 256 kbps audio bitrate is required, and allowing for the 20% IP overhead, a total of 10.64 Mbps full duplex bandwidth is required [= 3 streams x ((2.7 Mbps + 0.256 Mbps) x 120%)]. Additional bandwidth might be allocated for a document camera, or for the transmission of high resolution computer displays using HaiVision’s hai220 xGA Presentor technology (to transmit computer displays WITHOUT scan converting).
