  2. 2. A/V Meets IT Considerations  Immediate access to information and control  Network and Data Security  Network Management  Remote Service  Remote Tech Support  Remote Configuration
  3. 3. Traditional Matrixes are “Square”  Cross-point Architecture  4 x 4  8 x 8  16 x 16  32 x 32  Exceeding the capacity means moving to a much larger matrix  Central location  Central Control  Not generally expandable  Expensive
  4. 4. IP Matrixes can be:  Large number of sources; few displays
  5. 5. Or . . .  Large number of displays; few sources
  6. 6. Or even . . .  Multiple matrix clusters and displays under common control  Signals do not have to all run to a central location  Very long distances are possible over fiber
  7. 7. Start Small:  Buy only what you need right now  Only requires one Sender per Source; one Receiver per Display
  8. 8. Grow as you need:  Add more sources and/or displays at any time  No need to change existing  Hardware  Cabling  Programming  Network Infrastructure  Up to:  255 Senders (more coming!)  Supports thousands of devices (within network capacity limits)  Mix Source and Display Types:  HDMI  DVI  VGA (Within HDCP Compliance rules)  Long Distance Extension  Up to 100 meters between switches on Cat 6A cable  Up to 10Km over SM Fiber

Up to four users can control a source if desired
  13. 13. Recommended Network Switches Netgear PROSAFE GS728TXS Gigabit Stackable Smart Switch For cascaded or extended switch architecture, more than 1 Gigabit bandwidth may be required between switches. Offers four 10-Gigabit SFP uplink ports for expanded bandwidth between switches. Netgear GS724T A low-cost 24-port Gigabit Smart Switch that meets all of the requirements. It has two Gigabit SFP ports that can be equipped with fiber SFP modules for greater distances. SFP ports can be equipped with a variety of fiber and copper interface modules to allow a choice of fiber or copper media types, depending on the installation requirements. Juniper EX-2200- series Cisco Small Business SG300 or SG500X (“X” indicates it has 10G SFP uplink ports) These switches have been tested by the Gefen Technical Support Team, and we can offer configuration support. Many other products will work, but customers will have to determine the appropriate settings. Typical SFP Module:
  14. 14. Network Requirements: Successful Video‐over‐IP implementation requires involvement of the facility IT administrator as early as possible in the design process. • Managed Gigabit Ethernet switches are required. • 1080p video averages 150Mbits/s (burst transmissions can be higher) • Block all video traffic from any 10/100BaseT ports through switch configuration • Switches must support 8K Jumbo Frames • Switches must support IGMP query and snooping. • Internet Group Management Protocol prevents the multicast video traffic from flooding the network • Enable VLANs to separate video traffic from data and voice. • If data or voice are converged on the same network as video, careful consideration must be given to bandwidth management, or video frame‐rate will be unacceptable.
  15. 15. Simple System Example  Router is not required  PC or external controller sends commands to each Video-over-IP device and parses feedback to maintain matrix status
  16. 16. External System Controller  Pros:  Customizable interface  Can perform basic system routing  Can parse feedback  Good for simple applications (e.g. 2x2)  Cons:  Complex system build  Each unit must be addressed separately  No concurrent switching  Typically expensive  Require a specialist to install and maintain

  34. 34. Gefen Syner-G™ Discovery Tool  Gefen’s Syner-G Discovery Tool, also integrated into the EXT-CU-LAN, offers a solution to IP Addressing issues.  Each Syner-G-compatible device contains a Discovery “beacon” that allows the Discovery Tool to find and connect to the device, even if it is set to an incompatible Address, and even if it shares an Address with other devices, which would normally block it from communicating at all.  All new devices can be added at the same time, and the EXT-CU-LAN will allow each device to be quickly and automatically configured to the proper new Address and settings.  This is a tremendous timesaver, especially when configuring a large number of Video-over-IP devices into a video matrix.
  35. 35. System Design Examples
  36. 36. Simple System Example- with EXT-CU-LAN  Router is not required  Gefen EXT-CU-LAN is optional for control  EXT-CU-LAN manages setup and IP Addressing  EXT-CU-LAN manages commands and sends system status to PC or Control System  Controls devices via UDP for fastest switching
  37. 37. Cascaded System Example  Extend system via 10Gb fiber links between switches  SFP ports allow a variety of media options- copper, SM or MM fiber
  38. 38. Cascaded System Example A careful analysis of the network architecture will allow you to determine if the system will operate at full capacity without network congestion. In this example, with two sources on one switch and one on the other, there would be a maximum of three simultaneous streams through the fiber link. Adding more sources on the first switch would not increase the number of streams, since there are only two receivers connected to the second. 3 x 150Mbps max 1 2 3
  39. 39. EXT-CU-LAN Matrix Controller  Supports Dual LAN Connections  Separate Video and Control Networks  PoE Support on LAN1 Port (Control LAN)  (or 5VDC)  Video on LAN 2 Availability: Shipping
  40. 40. Split System Example  Separate video traffic from rest of LAN  Keep Video off Data LAN for Security  Control devices may be on either side
  41. 41. Using an External Control System:  CU-LAN Manages all devices and allows simple control.  Send either complete routing commands, or just Presets for simplicity.  CU-LAN greatly simplifies programming and configuration!
  42. 42. Resolving LAN Configuration Issues: All of the following settings should be checked to facilitate integration with an existing network (this may require assistance from your Network Administrator): • Remove Flow Control on any network port passing the video stream. • Enable IGMP query and snooping on all supported network switches. • Enable VLANs to separate video traffic from data and voice. • Set Jumbo Frames to 8K or higher. • Allow multi-cast traffic on all network ports through which video streams pass. • The CU-LAN units must have static or locked DHCP addresses. Senders and receivers may use DHCP, although static IP addresses are strongly recommended. For assistance with other configurations, contact Gefen’s Technical Support Team at (800) 545-6900 or
