Philips/TPVision-Innovation Site Europe, the branch of Philips developing TV/SmartTV sets.
Location: Belgium
Certification team: 20p
Member of Philips certification team, I had to design and develop a Remote test automation system to help distant teams in the world (Taipei, Bangalore) to access Philips SmartTVs as if they were in front of it so they can test and debug software versions and reproduce bugs or test cases, and I had also to develop Test Automation scripts for certification and system validation teams.

PROJECT DETAILS
•    Design a system architecture that meets the technical requirements (real-time access, resources access managing, roles / privileges, scalability).
•    Find and study solutions for technical obstacles met when implementing different features of the system (technology and means of implementation).
•    Embedded software development on Embedded Linux based ARM platform: Manipulate all inputs/outputs of a Philips SmartTV(LOGs, Audio, Video, PCMCIA/CI+, LNBs, IR, POWER, USB, Ethernet) and execute commands from control application.
•    Client software development on QT / C++: Remote control client application (real-time video, manipulate all inputs/outputs of the remote equipment), open and manage a VPN connection.
•    Features been implemented on the embedded equipment and control application:
-    VPN connection between ARM Boards and the client application.
-    Boards use a discovery algorithm to register and connected clients are managed with roles/privileges.
-    Real time AV Streaming from boards to clients.
-    File transfer & USB mass-storage emulation function between board and TV .
-    Drive all the switches connected to the board (DiSEqC™ and CI+).
-    Sending IR Commands to the TV.
-    Routing Uart connection to a TELNET console integrated in the client application.
