Samsung SSSP Controller
Even Samsung Digital Signage SSSP designed for 24/7/365, sometimes it can be freeze when running for long time. Samsung SSSP has protocol for able to remote the TV via LAN, it’s called SDP protocol. At the first release i was develop it using MCU ATMEGA2560 and W5100 ethernet chip. After deploying for several times, it has another problem: board on the TV freeze so can’t remotely turn on and turn off via LAN. Then i added SSR to cut TV power. Nice and well done, TV can be hard reset via remote. This helpful when the TV on unattended location.
