Samsung TVs have long supported a native app development technology called NaCl (Native Client) to enable developers to create truly premium, native high performance apps. However, until You.i Engine came along, there wasn't a dedicated workflow and UI tool to take advantage of NaCl on Samsung Tizen TV. You.i TV has developed a video app engine that consists of a unique game - like C++ SDK and workflow based on Adobe After Effects. You.i TV has been working closely with Samsung to integrate this workflow with Tizen TV to help top brands deliver high performance, premium video apps with full motion graphics. The You.i Engine is being used by top brands including Turner Broadcasting (TBS, TNT, Cartoon Network, Filmstruck), Fox and even the NBA. The You.i TV team will discuss: - Lessons learned with NaCl to help developers regardless of the workflow they choose - How to port comprehensive C++ based apps onto Tizen TV App using NaCl - How the You.i Engine workflow integrates with the NaCl API on Samsung Tizen - Demonstrate the full workflow from After Effects design to app implementation and ongoing changes - Answer critical questions regarding our experience with NaCl (developing, testing, deploying, issues to watch for etc)
