The MD6000™ provides high performance video transport system over SDH/SONET Networks. Advanced technologies, including error correction, hitless protection switching, and differential delay adaptation allow flawless transport of the most demanding types of video signals. Uncompressed HD-SDI, SD-SDI, SDTI, STM-I and DVB/ASI signals along with 10/100BT Ethernet can all be transported over a variety of networks, including OC-48/STM-16, OC-192/STM-64 or dark fiber.
IP Technology is key to the performance of the MD6000. Every incoming signal is divided into standard IP packets prior to transmission. This benefits users in several ways:
Forward Error Correction can be applied to each packet, eliminating the few inevitable bit errors that occur on fiber optic links.
Packet sequence numbers allow rapid, automatic detection of lost or delayed packets, which can be corrected with hitless switchover.
Smooth migration path from traditional SONET/SDH networks to IP core networks can be easily accomplished through an available software upgrade to support PPP protocol or to support Media Links video routers.
It avoids all the problems that result from compressed video, including:
Delays in both the encoding and decoding process.
Hidden compression artifacts in the video image.
Painstaking process to match encoding parameters to video/audio/data signal source with uncompressed video, its just "connect and go" regardless of the video format and frame rate - 1080i, 720p, 525/625 line, 50, 60 or 59.94 Hz, plus all types of embedded audio and data.
The MD6000 system works best for even the most challenging video transport applications, live transport of uncompressed video signals, and high quality news and live entertainment. Broadcasters have discovered that utilizing uncompressed video links is the most efficient way to transport content from one location to another, even for pre-recorded content. The MD6000 has a strong history of satisfying the most demanding users:
This technology was used to transport uncompressed HD and SD signals from stadiums in Japan to seven Tokyo-based broadcasters for live covereage of the 2002 FIFA™ World Cup.
MD6000 units successfully transported uncompressed video signals from Europe to Japan across North America via the Atlantic and Pacific oceans for the 2004 summer games in Athens and the 2006 winter games in Torino.
A permanent multi-broadcaster network has been established in Tokyo, and is expanding to other principal cities in Japan using MD6000 units. This network receives heavy use for both live traffic and for transporting pre-recorded material because of the network's low cost, high reliability, and uncompromising video quality.
Chassis and Power Supplies - Built with the most demanding users in mind, these components are designed for maximum durability and maintainability. All active modules (including fans) are hot swappable and monitored by the network management system.
System Management - All top-quality networking hardware needs to support performance monitoring and fault isolation. The MD6000 offers three different management interfaces:
A built-in web-server works with a user's normal web browser to give complete system status in an easy-to-read graphical layout. This server also provides a graphical user interface that simplifies system installation and configuration.
A detailed SNMP MIB is provided on each IP Switch to report critical system operational status in a machine readable form, allowing integration into popular software packages.
Hard-contact relays are provided for local alarming and in case of a complete input power failure

Hitless Protection Switching ensures delivery of pure, uninterrupted video signals even if the underlying SONET/SDH or IP network suffers a momentary outage or a 50msec protection switch. By using reduntant paths, and performing a packet-by-packet comparison of the incoming signals, the MD6000 can prevent minor or major network faults from impacting valuable video signals.
Differential Delay Adaptation allows hitless switching to work by automatically compensating for any differences in the signal transit times on the primary and secondary network links. To the user, this unique technology means that each signal interface can continue to provide clean, uninterrupted service even if either the primary or secondary network is interrupted.
System Components
Video Interface Module - One card handles all types of serial digital video, including SD-SDI, DVB-ASI, SDTI and HD-SDI. Each card is bi-directional, capable of simultaneously sending and receiving any signal type (even different types in each direction).
STM-I + Video Module - This multifunction card carries a full bandwidth, bi-directional OC-3/STM-I plus a 90 Mbit/sec DVB-ASI signal in each direction. This card can support all major types of 155 Mbit/sec signals, including ATM, IP, voice, compressed video, and audio.
HD-DPCM - This module accepts HD-SDI and utilizes high quality DPCM compression to reduce the signal rate to approximately 1Gbps which allows two HD-SDI signals and one SDI signal to be transported on an OC-48/STM-16.
SD-DPCM - Utilizes ITU J.81 DPCM compression to accept 2 SDI signals and carry them in half of the bandwidth providing twice the signal carrying capacity.
IP Switch Modules - The heart of the MD6000 system, these cards generate the high-speed output signals for a shelf full of video and data interfaces. One IPSW is enough to run the entire shelf; two are required for hitless protection switching over a redundant network. Two versions are available: the 2.4G model for STM-16/OC-48 networks, and the 10G model for STM-64/OC-192 networks.
Ethernet User Interface Board - The MD6000 Ethernet user interface module includes three 10/100BT Ethernet ports and one 10BT port. Four RJ45 connectors are located on the rear connector module. The MD6000 provides full bandwidth, full duplex point-to-point Ethernet connections between shelves.
