Abstract: A video data communication system for transmitting ultra-high definition video or three dimensional video stream over a packet switched network, including: an input receiving or obtaining plural high definition video streams representing a part of the ultra-high definition video stream or three dimensional video stream; a packet switched network transmitting at least part of the plural high definition video streams in parallel from a transmitter to a receiver; a receiver receiving the plural high definition video streams after the transmission over a packet switched network; a videogenlocker for generating a clock for the received high definition video streams and for synchronizing the received high definition video streams; and a combiner combining the synchronized received high definition video streams into a received ultra-high definition video stream or three dimensional video stream.
