Digital contentsedit

Traditionally content designs have been created by small, specialist firms However they are often seen to be expensive and have uncertain ROI2 More recently, digital content is created easily and flexibly via a Content Management System This means that new messages are created from a creative inventory of audio, video, image, graphics, words and phrases which assembled in different combinations and permutations to yield new messages in real-time

Digital content displayed on the signage is presented in one of the following formats:

Play media Video clip of a digital sign in Dearborn, MI, USA
  • Text - Scrolling text Either scrolling text, or text dynamically updated via external Newsfeed source
  • Images - Scrolling images, usually in the format of digital advertisement posters
  • Video - Usually in the format of commercial TV advertisements
  • Interactive interfaces - Integration of signage with touch screen, beacons, sensors, RFID technologies, to allow for two-way communications with the users Interactive digital signage helps to engage users and may also assist advertisers to gain insight in customer behaviour
  • Context-aware interfaces 3 - Integration of signage with cameras, sensors and software to monitor the ambient environment and audience, allowing signage to be updated according to the audience profile, weather conditions or some other relevant external factor

Content management systems CMSedit

Since digital signage content may be frequently updated using content management systems, and also because of the interactive abilities available through the accompanying employment of real-world interfaces such as embedded touch screens, movement detection and image capture devices which enable these forms of signage to understand who and how users are interacting with them, they are gaining acceptance as an alternative to static signage

Digital audiovisual av content is reproduced on TVs and monitor displays of a digital sign network from at least one media player usually a small computer unit, but DVD players and other types of media sources may also be used Various hardware and software options exist, providing a range of different ways to schedule and playback content These range from simple, non-networked portable media players that can output basic JPG slide shows or loops of MPEG-2 video to complex networks consisting of multiple players and servers that offer control over enterprise-wide or campus-wide displays at many venues from a single location The former are ideal for small groups of displays that can be updated via USB flash drive, SD card or CD-ROM Another option is the use of DAN Digital Advertising Network players that connect directly to the monitor and to the internet, to a WAN Wide Area Network, or to a LAN Local Area Network This allows the end user the ability to manage multiple DAN players from any location The end user can create new advertising or edit existing advertisements and then upload changes to the DAN via the internet or other networking options

Developments in web services have meant the APIs for some digital sign software now allow for customized content management interfaces through which end-users can manage their content from one location, in a way which suits their requirements

More advanced digital sign software allows content to be automatically created by the media players computers and servers on a minute-by-minute basis, combining real-time data, from news, to weather and prices, transport schedules, etc, with av content to produce the most up-to-date content4

Personalised digital contentsedit

One specific use of digital signage is for out-of-home advertising in which video content, advertisements, and/or messages are displayed on digital signs with the goal of delivering targeted messages, to specific locations and/or consumers, at specific times This is often called "digital out of home" DOOHH56



Interactive Digital Signage allows end users to interact the displayed digital content via Touch Screens, Body Sensor or QR code via smartphones

Digital signs can interact with mobile phones using SMS messaging and Bluetooth SMS can be used to post messages on the displays, while Bluetooth allows users to interact directly with what they see on screen In addition to mobile interactivity, networks are also using technology that integrates social and location-based media interactivity This technology enables end users to upload photos and messages to social networks such as Twitter and Facebook as well as text messages to the displays

The wide spread of smartphones lead to the development of screen–smart device interaction technologies These allow smartphone users to interact directly with the digital signage screen, for example participate in a poll, play a game, or share social network content

Context-Aware Digital Signageedit

As the name suggests, context-aware digital signage leverages a number of technologies such as sensors, cameras, beacons, RFID technologies, software programs and network connectivity including the Internet of Things IoT to monitor the ambient environment, process information in real time, and deliver highly relevant promotional messages based on an interpretation of environmental cues7 Many of the newer context-aware digital signage products are fitted with cameras and gather shopper demographic data by estimating the age, gender and social class of passers-by and use this information to update signage as well as to provide users with back-end analytics and shopper profiles

Other innovationsedit

New technologies for digital sign are being developed, such as three-dimensional 3D screens, with or without 3D glasses see Anaglyph image and Autostereoscopy, 'holographic displays',8 water screens and fog screens9

Markets and applicationsedit

While the term "digital sign" has taken hold throughout most of the world, some companies and organizations prefer to use the terms "narrowcasting", "screen media", "place-based media", "digital merchandising", "digital media networks", "digital out-of-home" or "captive audience networks" The term Digital Signage was first coined in early 1992 when a network of videowalls in UK Shopping Centres run by Neil Longuet-Higgins of ProQuip and Centre Network Television was referred to as a digital sign by a security guard who did not understand the term Videowall Neil Longuet-Higgins from SIS Digital was then the first to use this term to promote the nationwide network of 'Digital Signage'citation neededThe Out-of-Home Advertising Association of America OAAA defines digital billboards those that “offer static messages that rotate every few seconds with typically six to eight advertisers sharing the same location"10 Digital signage is evolving so rapidly that even the OAAA definition appears to be outmoded given that interactive digital signage and context-aware digital signage is anything but static

Digital Signage Market size is forecast to be worth USD 2302 billion by 2023; as per a new research report by Global Market Insights, Inc Lower paper wastage coupled with LED backlit panel integration has led to significant energy savings, driving digital signage market growth The emergence of Internet of Things IoT has the potential to transform the technology from mere content displayers to a hub capable of collecting operational data via cloud computing

China currently leads the world in the number of digital sign displays deployed and number of NASDAQ IPOs Total revenue from the digital sign equipment market in the United States – including hardware, software, installation, and maintenance—is expected to grow by about 33% in 200911 Another source for information on digital sign displays and impressions the number of times a viewer reads/views digital sign, is a report provided by Nielsen, the "4th Screen Network Audience Report" In it Nielsen identifies that digital screens in the "fourth screen" category in the US generated over 237 million monthly exposures to persons 18 years or older The report identifies Screenvision, NCM, Captivate, GSTV and IndoorDirect as among the companies that are leaders in the fourth screen category One of the leading digital sign companies in movie theaters is Screenvision, with over 14,400 screens in the US; another leader in the "fourth screen" marketplace is GSTV Gas Station TV, which reportedly generates over 32 million digital sign impressions every month Nielsen estimates these 237 million+ exposures translate into more than half 54% of the adult population being exposed to a place-based video ad during the period measured12

Digital signs are used for many different purposes and there is no definitive list However, below are some of the most common applications of digital sign:

  1. Public information – news, weather, traffic and local location specific information, such as building directory with map, fire exits and traveler information
  2. Internal information - corporate messages, such as health & safety items, news, and so forth
  3. Product information – pricing, photos, raw materials or ingredients, suggested applications and other product information - especially useful in food marketing where signage may include nutritional facts or suggested uses or recipes
  4. Advertising and Promotion – promoting products or services, may be related to the location of the sign or using the screen's audience reach for general advertising
  5. Brand building – in-store digital sign to promote the brand and build a brand identity
  6. Influencing customer behavior – directing customers to different areas, increasing the "dwell time" on the store premises, and a wide range of other uses in service of such influence
  7. Influencing product or brand decision-making - Signage at the point of sale designed to influence choice eg Signage to help shoppers to choose dresses inside a fashion store 13 or devices that on a computerized shopping trolley helping the customer locate products, check prices, access product information and manage shopping lists14
  8. Enhancing customer experience – applications include the reduction of perceived wait time in the waiting areas of restaurants and other retail operations, bank queues, and similar circumstances, as well as demonstrations, such as those of recipes in food stores, among other examples
  9. Navigation – with interactive screens in the floor, for example, as with "informational footsteps" found in some tourist attractions, museums, and the like or with other means of "dynamic wayfinding"

Equipment and network infrastructureedit

Digital signs rely on a variety of hardware to deliver the content The components of a typical digital sign installation include one or more display screens, one or more media players, and a content management server Sometimes two or more of these components are present in a single device but typically there is a display screen, a media player, and a content management server that is connected to the media player over a network One content management server may support multiple media players and one media player may support multiple screens Stand-alone digital sign devices combine all three functions in one device and no network connection is needed Digital signage media players run on a variety of operating systems including Windows, Linux, Android and IOS

LCD and LED displaysedit

Digital sign displays may be LCD or plasma screens, LED boards, projection screens or other emerging display types like interactive surfaces or organic LED screens OLEDs Rapidly dropping prices for large plasma and LCD screens have led to a growing increase in the number of digital sign installations15 An array of these displays is known as a video wall

Digital signage displays use content management systems and digital media distribution systems which can either be run from personal computers and servers or regional/national media hosting providers In many digital sign applications, content must be regularly updated to ensure that the correct messages are being displayed This can either be done manually as and when needed, through a scheduling system, using a data feed from a content provider eg Canadian Press, Data Call Technologies, Bloomberg LP, Thomson Reuters, AHN, or an in-house data source

Whenever the display, media player and content server are located apart there is a need for audio-video wiring between the display and the media player and between the media player and the content server The connection from media player to display is normally a VGA, DVI, HDMI or Component video connection Sometimes this signal is distributed over Cat 5 cables using transmitter and receiver baluns allowing for greater distances between display and player and simplified wiring The connection from media player to content server is usually a wired Ethernet connection although some installations use wireless Wifi networking


JPEG images and MPEG4 videos remain the dominant digital content formats for the digital signage industry For interactive content, HTML5 and Unity3D are widely used due to their popularity among web developers and multimedia designers

There are a number of technologies which are hoped to have improve standardisation and interoperability of the digital Signage industry, such as SMIL and POPAIcitation needed POPAI has released several digital sign standards16 to promote "interoperability between different providers" The objective of these standards documents is to establish a foundation of performance and behavior that all digital sign systems can follow
