This article outlines a case study in which the author employs a Raspberry Pi 3 miniature computer as a Digital Signage System, which can be managed from either laptop, smartphone or desktop computers. The author presents it as a case study that high school students (and their teachers) can follow, as a collaborative project that delivers a cost effective and flexible, digital signage system for their school. While it does not require any coding on their part, it presents an excellent use of ICT, by configuring multiple interrelated hardware and open software, in a school community setting, that would fit in with many contemporary digital technology curriculums.

Digital signage systems are large format displays that are typically installed in public areas for advertisement and informative publications. This emerging technology is considered as a major category in the large format display market. In general, a digital signage system consists of a flat panel display consisting of high brightness screen and operation circuits. Also, special features of high performance embedded computing system exist in very small form factors. Such products, however, are accompanied with high heat dissipation of the internal components and are usually exposed to very harsh environments for more frequent exposure to customers. Also the installation schemes of the products vary for different objectives, and a robust thermal design is required to guarantee the system reliability considering corner scenarios within the design space. The objective of the present study is to investigate the effect of installation environment on the thermal performance of a display assembly resembling a digital signage system. Design criteria for a proper thermal management scheme are proposed. The thermal characteristics of a digital signage system are presented in various operation conditions and each thermal design parameter is discussed thoroughly to ensure the reliability requirements of the digital signage system are met.

Client Side

Interactive digital signage is an important Internet of things application and has been becoming a common type of human–machine interface for multiple users. By integrating with wireless sensor networks, a digital signage system can provide smart features and on-demand contents to users. However, the performance of current interactive digital signage systems depends heavily on the server. An increasingly high number of digital signage clients and sensor devices attached to the system generating a huge amount of traffic flowed to the server may create bottleneck, management and scalability issues at the server, especially in large-scale digital signage systems. In addition, the current system requires application installation and configuration at the client side, thus leading to a high cost and complexity of deployment as well as management. This article proposes and implements a container-based distributed virtual client architecture for interactive digital signage to solve the above issues. In the proposed architecture, a number of digital signage clients and Internet of things devices are virtualized and managed by a container-based middleware. Each container-based middleware is responsible to manage and process data for a cluster of digital signage clients and corresponding Internet of things devices to (1) reduce load to server and improve the service performance and (2) enable lightweight clients to reduce cost and complexity in deployment as well as management. Implementation and obtained analysis results show the advantages of the proposed architecture.
