Japan Broadcasting Corporation (NHK) has reportedly developed and demonstrated a Super Hi-Vision (SHV) program on 7680 x 4320 pixels. By comparison HDTV, which is being slowly adopted by TV channels worldwide, has only 1920 x 1080 pixels. The next generation broadcasting technology uses an SHV camera equipped with 8 megapixel CCD image sensors that can take 4k x 8k images. The technology was demonstrated at a sea park in Japan by sending two cameras that sent baseband signals without image compression over a 161-mile long fiber-optic network.
“Super Hi-Vision has huge information and was difficult to transmit,” said NHK research engineer Mikio Maeda. “Using 16 waves on optic fiber, we succeeded in a live relay over a long distance. This means that SHV proved the possibility of being a future TV broadcasting technology.”
