Digital Sign Management: Learn How SNMP Messaging Improves Network Monitoring

The use of simple network management protocol (SNMP) messaging can make it much easier to manage a digital signage network.

If you don't want to be the Erich Brenn of your digital signage network, you might want to consider how SNMP (simple network management protocol) messaging can help you lead a happy, productive professional life.

For those who don't recall my last column, Erich Brenn was "The Ed Sullivan Show" performer who impressed me as a young boy for his ability to keep numerous bowls and plates spinning. His feat required a high-degree of attention and some pretty quick feet.

I envision administrators of digital signage networks without the proper tools to be in a similar space as Brenn -constantly running from one display monitor to the next to confirm playback, inspect presentation quality and identify potential problems on the horizon. Unfortunately, for the network administrators, the distance they must cover isn't the length of a dining room table, but rather can be as great as across a mall, a campus or even around the world.

One tool at the disposal of digital signage network administrators is SNMP messaging. The idea behind SNMP is devices on the network -for instance a local digital signage player, whether it's integral to the monitor or a standalone device connected to the display- are equipped with the ability to monitor their condition and alert a central server of problems or potential problems. Local condition monitoring of these devices is done via an agent that reports information via SNMP messaging.

So, for instance, one simple task of an SNMP agent in a digital signage network is reporting. In this example, an agent can be setup to report in to the central server at specific intervals, letting the system and the administrator know that the device is still connected to the network and on. However, if there's a problem and the agent fails to report in at the expected time, the server immediately knows there is a status problem with the device that must be addressed. Communications in the form or an email or text message can be sent to the administrator so the issue can be corrected. SNMP can allow a variety of conditions to be monitored, reported and acted upon. Others might include temperature, moisture and even component-level warnings where available.

While SNMP messaging is a smart way to monitor, report problems and ultimately take corrective actions, it's also stupid. Or, more accurately, SNMP doesn't have the smarts to do anything more or less than the administrator asks.

Thus, if an administrator tells an SNMP agent to report in to the central server every minute with a status report, that's exactly what it will do. If the action that's tied to a failure to report is to send out an email to the administrator every time the device fails to report that administrator may one morning be greeted with literally hundreds of emails reporting the failure of that player on the network. While an annoyance, simple steps like extending the reporting interval can reduce those emails from hundreds to a handful.

SNMP is a valuable tool that digital signage network administrators can use to sidestep emulating Erich Brenn. Another is serial control, which I'll explore in my next column.

Digital Signage Management: How to Keep All the Plates Spinning

Share |

As digital signage network size and complexity grows, remote monitoring and control become essential.

One of my earliest memories as a small child was sitting down with my folks to watch the "Ed Sullivan Show." Many may remember the variety show for the historic appearance of the Beatles and the beginning of the British invasion. Others still may remember the program for the host's famous catch phrase -something like, "We have a really big show" with the word "show" sounding exactly like the drawn out pronunciation of the word "shoe."

What I remember the most was a stage act in which the performer began spinning bowls on wooden poles protruding from a platform. As the act progressed he also began spinning up dinner plates, positioned between the poles balancing the spinning bowls, on their edges. To keep all of this in motion, the performer would run back and forth between poles, adding more spinning momentum to the bowls as he added more plates and bowls to the action. To the amazement of this little boy watching in awe with his parents, not a single bowl or plate crashed to the ground; rather the performer concluded his act by collecting each spinning object and neatly arranging them on the platform.

This childhood memory paints a mental picture for me of what it must be like to manage an extensive network of digital signs without proper monitoring, alert notification and control functionality. I can see in my mind's eye some poor soul having to run between monitors to make sure they are on, playing back the right content and functioning properly. But instead of traversing the width of platform no bigger than dining room table, this digital signage manager would have to run back and forth between signs scattered around an arena, across a campus or even around town.

Fortunately for digital signage network administrators, tools exist to eliminate the need to visit individual displays in person and instead provide the ability to remotely monitor and control all displays from a central command center.

Various approaches can be taken, but some of the more useful elements in any such system include support for: SNMP (simple network management protocol messaging); snapshot confidence monitoring of all displays on the network; serial control of monitor functions, including on, off and volume control; and some degree of network and device diagnostics.

Without these basic tools, managing, controlling and monitoring the performance of a digital signage network would be a feat akin to keeping all of those spinning plates and bowls in motion.

In future columns, I'll layout more details about each of the important elements of digital signage network monitoring and control, but for now, I just wanted to set the table with lots and lots of spinning plates and bowls.

One final note: If you are interested in seeing the spinning plate and bowl act, go to YouTube and search for "Erich Brenn 'Plate Spinning' on The Ed Sullivan Show."

Cheers & Happy Holidays

Digital Media: Keeping it Relevant in a Changing Landscape

Share |

As mobile media makes inroads into the public consciousness, digital sign communicators can use relevancy and timeliness to cut through the clutter.

One open secret about the success of dynamic signage as an out-of-home medium is that often the audience for the signs does not have a whole lot of choice when it comes to selecting what media to consume.

That's not to say dynamic sign viewers are a "captive audience," but they often have been easy to grab because they typically didn't have other video-based media competing for their attention. Congregating in lobbies, cafeterias, medical and dental waiting rooms, car dealer service areas and other common areas, many members of digital signage audiences welcomed the chance to let their attention focus on the sign rather than reading a newspaper of magazine they may have already seen.

But that's all changing. Wireless 3G and 4G networks turn mobile phones into media players, and YouTube, Hulu, and other video Web portals make Internet TV easy to access. Add to that the fact that new mobile digital TV broadcasting capable of delivering local TV broadcasts to personal/portable devices is right around the corner.

Suddenly, just having a digital sign located where people congregate isn't good enough. Suddenly, there is competition for the attention of viewers. Suddenly, it's more important than ever to create fresh content that is relevant to the intended audience of the digital sign and to make sure it is timely.

A recent article in a Connecticut college newspaper discussed the attempt of the leader of a student government group to build support among school administrators for installing digital signage on campus. The student government leader saw digital signs as a way of building school spirit and creating a more unified campus community. As part of effort, students were surveyed to find out what they thought about the idea.

Of 400 students polled, 56 percent said they thought digital signage would likely raise awareness among students about the goings on around campus -a respectable finding for proponents of digital signage.

Another finding, however, speaks to the importance of keeping digital sign content timely, relevant and informative. Respondents to the survey told researchers that the effectiveness of any digital sign installed on campus would be tied closely to updating information regularly on the signs.

The college students responding to the survey expressed an opinion that's likely to grow increasingly prevalent among digital signage audiences as wireless video media become available to a growing segment of the population. For dynamic signage content to be consumed, it needs to be fresh and a valuable source of information. Otherwise, the audience that once could only choose between a back issue of some mildly interesting magazine and a dynamic video sign may increasingly turn to a third alternative, namely personal mobile media devices.

For some digital sign communicators the concept of competition for attention may be a foreign one. But the evolving media landscape in this nation that's putting video content within easy reach of anyone on the go is changing all of that. It's time to redouble efforts to keep digital signage content relevant, fresh and interesting.

Digital Media Delivers Effective Emergency Communications On Campus

Share |

A new study from the Platt Retail Institute reaffirms how effective digital communications is in distributing emergency warnings and alerts on campus.

In late September, a gunman opened fire inside the library on the campus of the University of Texas in Austin.

For many of us old enough to recall, news of the event immediately triggered memories of Charles Whitman, the sniper who fired down upon the campus from the University of Texas Tower in August 1966. While the specifics of the two events are quite different, a major, yet easy-to-overlook difference is particularly noteworthy: campus communications. Forty-four years ago, radio and television carried the burden of warning the public about the presence of the sniper. Unfortunately, not many people at universities tune into radio or TV during class.

Today, new digital means of communications abound, and spreading the word that a gunman has opened fire on campus can be immediate, focused and highly effective. Text messaging, e-mails and cell phones make it simpler for campus authorities to reach individual students and faculty within minutes of an event occurring.

Digital signage is also an important component in this digital communications mix. After all, many students are advised to turn off their cell phones during class, so the availability of emergency messaging on digital signs strategically located around a campus provides another layer of protection in the process of communicating urgent emergency messages to students, faculty and staff.

A new study from Platt Retail Institute, "Communication Effectiveness in Higher Education" reveals the significant role of digital signage in communicating on campus. A press release announcing the study quotes Steven Keith Platt, PRI Director and Research Fellow as saying: "Our research study found that 97 percent of students prefer to receive information via digital channels, rather than from non-digital sources. Overall, text messages were found to be the most effective distribution channel, followed closely by digital signage."

It's important to note that emergency messages delivered via digital means like text messages and digital signs do not have to relate simply to shootings. A variety of emergency situations require quick, accurate communications. Universities and other institutions regularly plan for contingencies such as fires, earthquakes, tornados, severe thunderstorms and many others. Developing an effective communications strategy that taps the power of digital communications should be part of that contingency planning.

When it comes to digital signage and emergency communications, a variety of specific pages with the appropriate emergency-related information should be prepared prior to any event as part of a well-planned, campus-wide digital signage network. In the event of any given contingency happening, pages can quickly be updated with event-specific information and distributed to all or some of the signs on the network.

Having been involved with the planning and roll out of some of these systems, I want to offer a few ideas for those who haven't given digital signage and emergency communications much thought. First, the digital signage network administrator should coordinate with on-campus and off-campus first responders as digital signage pages are prepared for various contingencies. Often, plans already exist and can be drawn upon to create effective communications.

Second, provide for Internet access to digital signage control in case the emergency circumstance prevents access to the campus command and control center and the computers ordinarily used to drive digital signage messaging. Third, be sure to password protect access to the digital signage network.

While the very thought of a gunman on campus, a tornado striking a building or some other contingency is tremendously disturbing, it is necessary to plan for them before they happen. Effective communications can save lives, and supplementing text messages and emails with emergency digital signage messaging might mean the difference between preserving innocent life and a lifetime filled with regret.

OOH Advertising: Out-of-Home Advertising Boosts Impact of Other Media, Delivers Sales Lift

Share |

A new study from Clear Channel Communications and MarketShare Partners demonstrates the benefits marketers can expect from adding out-of-home advertising to their media mix.

Marketers looking for evidence that out-of-home advertising can improve sales and amplify the effectiveness of their other advertising need look no further than a new study from Clear Channel Communications and MarketShare Partners.

The study, "How Out-of-Home Advertising Works," examines the return on investment of using out-of-home advertising as an ingredient in a larger marketing mix. Specifically, the report finds OOH advertising provides a significant, incremental sales lift that equals, or is often greater than, other drivers.

"After careful analysis of thousands of marketing optimization models, and considering decades of research and applied marketing science, independent research from MarketShare Partners conclusively shows that OOH is an effective marketing vehicle and should be included as a component of the optimal marketing mix across a broad range of industries," said Debbie Reichig, senior vice president of Business Development and Marketing at Clear Channel Outdoor.

So what can marketers expect from OOH advertising? Quite a lot, actually. A press release announcing the report outlines some of key benefits, including:

Adding OOH in the media mix, for industries and products where it provides observable sales lift, makes other media more effective.
OOH can provide a significantly higher sales lift in conjunction with TV when the creative messaging is coordinated across platforms.
OOH can provide a significantly higher sales lift in conjunction with radio when there is a call to action.

As I've discussed before, out-of-home advertising using a medium such as digital signage networks is making great strides these days. Recent developments in technologies and techniques to count audience elevate the stature of OOH advertising in the minds of marketers and ad agencies alike.

The latest study from Clear Channel Communications and MarketShare Partners advances the medium further still. It not only demonstrates how OOH ads can provide a sales lift when used together with radio and TV advertising, but it makes specific recommendations on the optimum allocation of marketing resources to out of home.

The study finds the best allocation of marketing dollars to OOH advertising falls somewhere between 5 percent and 25 percent of the total advertising budget for most products and brands.

While some may discount this study as self-serving -after all Clear Channel Communications recently announced its recommitment to OOH ad networks and is one of the largest purveyors of outdoor advertising in the world- to do so would be shortsighted in my opinion. Sure this company has an interest in OOH advertising, but both Clear Channel and MarketShare Partners have an equally strong interest in protecting their reputation in the industry. To do anything other than to look honestly and completely at OOH advertising in the report would be harmful to both enterprises.

I applaud the companies and the release of "How Out-of-Home Advertising Works." The study offers the advertising and marketing communities key insights at this important stage in the development of OOH advertising on digital signage networks. Not only does the study demonstrate how OOH advertising can help marketers achieve their goals, it quantifies what portion of their ad budgets should be allocated to this medium to maximize the effectiveness of their advertising efforts.
