A low-cost solution to improve video projector management and connectivity using virtualization

The video projector is an essential tool for various activities such as teaching, organizational tasks, and conferences. This article introduces a low-cost and effective architecture designed to enhance video projection resources, including older models, through the incorporation of virtualization for improved management and sharing capabilities. The proposed solution addresses prevalent connectivity issues caused by differing connector types, transmission protocols, and configuration incompatibilities (such as frequency and resolution) between video projectors and computers. These incompatibilities frequently lead to delays and challenges in effectively utilizing video projection resources.

The innovative architecture utilizes a Raspberry Pi combined with three virtualized applications to create a user-friendly system. This system not only facilitates the efficient management of video projection resources but also allows for seamless sharing and connectivity across various devices. By leveraging virtualization, the architecture ensures compatibility and adaptability, reducing the downtime typically associated with setup and configuration issues.

The implementation of this solution is aimed at enhancing the functionality and accessibility of video projectors, enabling new paradigms in working and teaching environments. The approach provides a low-cost and practical method to upgrade existing video projection infrastructure, thereby extending the lifespan and utility of older projectors while introducing modern capabilities and improving overall user experience.
