Sony introduced the worldwide first 4K content distribution system with its first 84″ 4K TV. The complete system comprised a 84″ 4K TV, along with a PC based 4K content player, a tablet to control the 4K content player and a backend service – the content delivery service with feature films was a world-wide first, and a Sony differentiation for more than a year. The tablet application, the 4K server and the content processing pipeline have been developed and operated by the San Diego engineering team. CNet has a video that shows the tablet application in action.
The complete system was announced at CES 2012 by Phil Molyneux (COO and President of Sony Electronics), and developed from scratch afterwards.
