Raspberry Digital Signage (RDS) is an operating system designed for digital signage installations on the Raspberry Pi. It displays a full-screen browser view restricted to a specified (web) resource. The project has released a new version, Raspberry Digital Signage 10.0, which is based on Raspbian "Stretch". The release announcement reports: "Marco Buratto has released Raspberry Digital Signage 10.0 today, which comes with the latest and greatest Chromium build (featuring advanced HTML5 capabilities, Adobe Flash support and H264/AVC video acceleration), so you can display more attractive resources, more easily. System parameters are set by a web interface which wraps lower terminal commands. SSH and VNC remote management systems are available as well. Changelog for version 10.0: The underlying operating system has been moved to Raspbian Stretch; the overall performance is sensibly better and HTML5 videos play a lot smoother; some improvements on code and bug fixes (the most important ones concern WiFi networks' discovery and local WordPress virtual host, which remains disabled if unused)."
