Digital signage is revolutionizing the media and information industries by suffering the tonal and rapid update of content and its immediate delivery to specific audiences in specific locations. Components of Digital Signage The components needed for a digital signage system include: An authoring console, equipped with content management software, indulgent the definition of content in a variety of playback formats. A server, to which finished content is uploaded and from where it is distributed to different displays in the network. A distribution infrastructure, consisting of a data network or fiber optic or CAT5 cable, which broadcasts media from the server to the displays. Digital signage displays, which can be plasma displays, LCD monitors, CRT monitors, or kiosk stations. Benefits of Digital Signage Digital signs have thus far brought significant benefits to businesses and media vendors alike: Attention grabbing promotion A digital sign brings innovation and movement to previously static media locations, and has the power to get customers' attention, making it a particularly effective form of advertising. Real-time and information Digital signage allows build-up and information to be updated on the fly from one remote authoring station and commercial program immediately to audiences regardless of location. Relevant audiences With digital signage, publicity focuses on the best potential customer: an existing one. Supermarkets have formerly found that current customers are more likely to purchase products advertised on their digital signs. Cost savings Every time digital signage users equal their message or campaign, they save on printing costs and processing time. Profit center opportunities Businesses can create instant profit centers by selling time on their digital signs to customers or suppliers. DIGITAL SIGNAGE Uses of Digital Signage It is not surprising that, with all the benefits of digital signage, there are so many uses for it worldwide. They include: Advertising networks In-store advertising Interactive kiosks Tradeshow displays Corporate identity self-immolation Electronic menus and lobby displays Branch office communication Campus tally boards Community communique boards Arrival and departure schedules Franchise translation systems Emergency transference systems Corporate reply systems Back office employee training Digital Signage Distribution Technology: “What Lies Beneath” When considering a digital signage project, users usually focus on display types and content management software. For the integrator, however, there is an important component that the user rarely considers: the distribution technology and platform. This infrastructure transmits the digital video and phonic from the server to the appertaining displays, and is a key contributor to incontestable digital signage performance. In addition, as the connecting component for all displays, the distribution technology can be a significant part of the project budget. That’s why selective the correct distribution technology is vital in ensuring a successful digital signage installation. Options for Digital Signage Distribution There are three main options for digital signage distribution: Data network Fiber-optic cable CAT5 lead In this paper, these options will be presented together with the core considerations in first choice a distribution technology: Cost Performance Existing infrastructure Digital Signage Distribution Options: Platforms & Combinations Each platform has its own benefits and drawbacks. When harnessing more than one platform. There are a number of interesting combinations as discussed below. Data Network Platform A data network platform uses a computer network infrastructure in order to transmit content in the form of compressed multi-media files (such as MPEG files) from the management station to the flat server and from there to the computer connected to the display device. The prime server handles distribution to multiple displays, and the display-end computer decompresses the file for display on the display device. Alternatively, if only one display is required, the network can transmit the compressed file directly from the management station to the display-end computer, which then decompresses and displays the file. Benefits & Drawbacks The usefulness of data networks depends largely on existing infrastructure. If there is an existing computer network infrastructure, using a data network platform for digital signage can save costs significantly. However, if no computer network then as previously exists, the need to implement such an infrastructure will increase costs considerably. An collateral cost related to data networks is executed by the need for display devices to be connected to local computers or equipped with embedded CPUs, resulting in extra investment in hardware, an important factor when costing the project as a whole. In addition, from a performance standpoint, using a data network platform has several disadvantages. A data network platform limits the user to the compression technologies approachable on the market today, technologies that significantly downgrade the quality of the multimedia content and the displays’ dependence on the network is added major consideration for 24x7 locales that cannot tolerate display downtime. Fiber Optic Extenders Fiber optic day letter is a transmission medium favored for applications that need high bandwidth, long distances, and complete immunity to electrical interference. That makes it ideal for digital signage, which requires high resolution and transmission over long distances. Unlike network platforms, fiber optic party line does not require CPUs or special software at the display end. All that is required is a transmitter and receiving unit for each display. There are two options for fiber-optic cable: single mode or multi-mode. Single-mode fiber provides a higher transmission rate and up to fifty times more distance than multimode, but it also costs more. In general, the decision needle different types of fiber should be the result of a simple cost-benefit evaluation: the distance and level of resolution or performance required versus the pretty good investment in distribution technology. Benefits & Drawbacks Fiber optic line is optimal for transmitting high-resolution multi-media over long distances, a feature which makes it particularly unique for digital signage. Fiber optic telephone line provides network-independent performance without downtime or transmission lags. It can transfer media over 40 kilometers or more. In addition, it requires no special infrastructure, software or display-side CPUs. However, fiber optic is a point-to-point technology – in other words, a pure fiber optic electric cable solution will not consider the circumstances multiple displays to receive output from a single video source. This can prove a significant obstacle for multiple-display digital signage installations such as malls and airports. In addition, fiber optic braid has a high price relative to other technologies. Fiber optic cable’s expense can prove prohibitive when planning a large digital signage project. A possible solution, discussed below, is the agreement of fiber optic braid with other, less expensive solutions, tolerant the user to contribute to from fiber optic cable’s advantages while reducing the total cost of the project. CAT5 Distribution Systems CAT5 yarn is also a transmission medium favored for local installations that need high bandwidth and high resolution without any existing network infrastructure. CAT5 telex technology provides these advantages at a considerably lower cost than fiber optic cable. CAT5 technology supports real-time multi-media transfer through inexpensive, low density, twisted pair cabling. Benefits & Drawbacks In adducible ways, CAT5 technology as a distribution platform combines the best aspects of fiber-optic and network technologies. Like fiber optic technology, CAT5 technology requires no special software or display-side CPUs, and is completely hardware-based and network independent. Only transmitter and receiving units are required. While CAT5 covers shorter distances than fiber optic telegraph cable (typically 100-300 m/300-1000 ft), CAT5 transmission line costs considerably less than fiber optic cable, making it a leading option for corralling solutions which overcome CAT5 cable’s distance limitations. In addition, CAT5 technology can be used in point-to-multi-point applications, lax the bruit about of media content from one telephonist source to hundreds of display stations. As a result, CAT5 technology solitary or piled with fiber optic telephone line is an ideal solution for multiple-display digital signage installations. Due to its network independence, CAT5 party line allows high performance, real-time transmission of high-resolution multi-media without slowdowns or downtime. If CAT5 technology is blended with a BIOS-level hardware solution for remote wire-puller over IP (such as a KVM IP extender), it can even give the go-ahead remote maintenance and trouble shooting for the content server that manages the content to be displayed, minimizing down time and loss of investment. CAT5 cable’s low expense, ease of installation, and flexibility make it a good discrimination for a primary distribution technology as well as a leading “last mile” option for canvass platforms. Combination Technologies Because of the advantages and drawbacks of each of the technologies listed above, it is frequently wise to use a uniformity of technologies for optimal performance at the lowest possible cost. Fiber optic and CAT5 telex When dealing with high-resolution media over large distances that must be electrical transcription to a group of displays, a suspension of fiber optic and CAT5 radiogram is the optimal solution. In this case, fiber optic rope is used for distance dispersal together with a local CAT5 video master of ceremonies for “splitting” the publish to the various displays. This is a simple solution to install, since all that is needed is to connect the fiber optic receiver with the CAT5 video broadcaster. And the use of CAT5 flash for the last 50-150 meters/150-500 feet of cabling instead of fiber optic line can provide significant savings. Benefits High resolution & performance Hardware solution Point to multi-point No special infrastructure or display-side software required Network independent Long distance Supports groups of displays Lower cost than pure fiber optic Conclusion: By parasitic the two technologies into the same solution and using the true advantages of each type of electric cable you were able to save as good as 17% or $17,500 in direct costs to your customer. Data Network and CAT5 transmission line When managing multiple groups of digital signage displays from a remote location, a solution of data networking and local CAT5 cabling can give the user the best of both worlds: remote management over IP united with low-cost and network-independent infrastructure. The “last mile” use of CAT5 in place of data networks at the display end saves the cost of a computer (or CPU) for every display. All that is needed is a local equidistant server, which is remotely managed through the data network. The local server is connected to multiple displays through CAT5 technology, freeing the local installation from network dependence. The digital signage of each location is network-independent, and each installation is far less expensive to implement. Bandwidth issues are also surmounted by transmitting media to the local computer foresightedly of time for scheduling on-the-fly. At the time of broadcast, media is transmitted locally over CAT5 cabling, which is network independent and not limited by bandwidth. Benefits Point to multi-point High resolution & performance No local infrastructure or display-side software required Locally network independent Low cost Conclusion Distribution infrastructure is an important part of digital signage, and appointive the correct distribution technology is a crucial element of any digital signage project. While each distribution technology has its advantages and drawbacks, the correct brew of technologies can bring to fruition low cost and high performance no matter what the project size or complexity.
