At the prestigious international trade fair Inter BEE 2018 in Tokyo, the CESNET association and intoPIX presented a technology for transmission of video at 8K resolution, which is 7680 x 4320 pixels. No comparable solution is available on the market. The technology for transmission of 8K video over the Internet uses a field-programmable gate array (FPGA) with very low added delay. By employing a TICO codec and creating a system working fully in real time in the FPGA circuit, CESNET has cut down the delay to approximately 1 ms. Another advantage of the hardware implementation is high energy efficiency and small dimensions. The encoder and decoder for 8K video consume approximately 20 W each.
At present, the technology can transmit up to 60 frames per second; an upgrade to 120 frames per second will be possible with the same FPGA circuit in future. The solution will find applications in science and research, at cultural and sports events, and has potential for television broadcasting.
