6 Reasons to switch to digital KVM

Analog technology can’t keep up in the digital marketplace. Digital video is sharper and digital KVM is faster. Don’t get left behind in the digital revolution.

1. The VGA standard is being discontinued.
The VGA standard will not be supported going into 2015. Analog KVM and video won’t work any longer either. VGA sources and displays are getting increasingly difficult to find. We recently heard from a client who had to buy VGA parts on eBay.

2. Digital technology is distinctly better.
Digital technology improves users’ experiences by providing crystal-clear images at any supported distance. HD video is delivered pixel by pixel to digital displays at higher resolutions and increased color depth.

3. Digital systems are bigger and better.
New larger matrices and IP-based systems increase flexibility and enable connecting to a much higher number of endpoints. Thousands of devices can be incorporated into one unified system. On a digital matrix system, I/O ports are interchangeable, making changes and adds as simple as plugging a device into a port.

Case Study: Major broadcaster adopts multiuser matrix system for upgraded studio

Broadcasting studio personnel, from engineers to editors, are on the search for extension and switching solutions that work for multiple users. Issues to avoid are delayed switching times, no simultaneous access for multiple users, and limited USB device support. Broadcast engineers need to reliably extend and switch high-quality video and audio. They also want to use the most up-to-date infrastructure to hand and have a scalable, future-proof system.

A major network studio in Chicago came to us with a wish list for its broadcast studio upgrade. The chief hardware engineer was looking for a video extension and KVM matrix switch that would work over the existing Ethernet network in the studio. The system needed to enable forty producers, directors, studio technicians, and operators to gain access to more than sixty computers, servers, video sources, and camera feeds from any desk location.

The Chicago studio produces live broadcasts. Transmission glitches were unacceptable. The system needed to enable forty producers, studio technicians, and operators to gain access to more than sixty computers, servers, video sources, and camera feeds from any desk location. Flexibility and scalability were vital.

The system that had been deployed prior to our involvement cased daily problems and numerous help desk tickets. The problems included delayed switching time, lack of simultaneous access for multiple users, limited device support for USB HIDs, uneven video and audio quality, and poor system reliability and durability. We needed to address all these issues at once.

Making teamwork a snap in the broadcast booth

The Dayton Dragons are the very successful Single-A affiliate of the Cincinnati Reds, and currently hold the longest sell-out streak in all of North American professional sports. They were even voted one of the top ten hottest tickets to get in all of professional sports in 2007 by Sports Illustrated. Owned and operated by Mandalay Baseball Properties, the team continues to produce high-quality, family-friendly entertainment and provide unsurpassed customer service to a large, loyal fan base. Mandalay Creative Services, a division of Mandalay Baseball, helps meet that goal by providing in-house system design, technical integration, and production services.

The Dragons’ commitment to creating an unmatched fan experience led them to upgrade their video, audio, and control systems prior to the start of the 2014 season. The team is unique in that they produce two separate productions—an in-house and a broadcast feed—with two separate crews sharing core system components. The caveat was that the crews and components were split between two rooms: one space for each production.

Mandalay Creative’s first key goal was to enable the two small but efficient teams to work across multiple systems, producing shows that would normally require big-league budgets and staffing. Their high standards also demanded no sacrifice in video quality, maximum uptime, and enterprise-grade reliability.

Also vital, the Dragons required a solution that would grow with them, providing easy and cost effective ways to add additional servers and users to the matrix routing system.

How to implement multicasting

While IP multicasting has many benefits, it also presents challenges. Multicasting delivers identical data to multiple receivers simultaneously, without transmitting multiple copies. So, when multicast data enter a subnet, the natural reaction of the switches is to send the multicast data to all their ports. This is referred to as multicast flooding and means that all the ports in that subnet (or at least their network interfaces) are required to process that multicast data even if they are not “seeing” this data. This can cause more data to travel across the network and slow or overrun the network infrastructure. IGMP (Internet Group Management Protocol) offers a solution to this issue.

Our MediaCento™ IPX extends HDMI video over any IP network to as many as 250 distant screens—or to video walls. You can run the MediaCento IPX in unicast (one transmitter to one receiver) or multicast (one transmitter to many receivers) mode applications. The unit can also support a video wall, using multicast mode to output a single source video to a matrix of screens, so that you can project your HD content on a larger scale with one image divided over multiple video screens.

For MediaCento IPX multicasting applications, it’s very important to choose the right Ethernet switch, one that can handle the requirements to multicast data in your network without flooding your IP infrastructure.
