NABShow, Las Vegas, United States – April 24, 2017 – NHK and Village-Island have developed a new innovative system, called VICO-8, that makes possible to transport 8K 4:2:2 60p 10bits on a single 12G-SDI cable using intoPIX TICO (TICO is said “high-efficiency codec” for its video quality and delay compared to the implementation cost (ex: cost of computing or FPGA) compression technology.

VICO-8 takes 8K video as 4x 12G-SDI input as compress by a factor of 4 to 1, in visually lossless (The PSNR (Peak signal-to-noise ratio) is measured commonly as above 48dB) quality, generating a single TICO 8K stream output mapped on a single 12G-SDI interface with a delay of few video lines, so less than 1msec.

8K 60p 4:2:2 (10bits) usually requires 16x 3G-SDI or 4x 12G-SDI for raw quality transport.

Such high number of SDI cables implies many drawbacks such as big space constraints, high costs and high complexity of wiring. Furthermore, a UHD signal spread on multiple SDI cables brings concrete problems for signal distribution, switching, transmission, and other basic operations.

The gain to bring 8K to a single 12G-SDI is huge. It enables to achieve 8K with 4K-ready appliances, wherever it is about switching, distributing, transmitting the signal on optical fiber or other support. Dividing dramatically the cost of infrastructure (The VICO-8 can be configured to generate the 8K TICO stream on 4x 3G-SDI as well, making it possible for 4K (4x3G-SDI) devices to handle 8K), the gain of VICO-8 is even exponential when considering matrix switcher where VICO decreased the number of required input by 4, while decreasing the number of required output by 4, dividing the number of required node by 16.

The VICO-8 was developed in collaboration with the NHK, a pioneer in Super Hi-Vision technology. “The gain of using VICO-8 can be dramatic within our 8K OBVAN where the constraints on space, heat, wirings, energy are the most challenging” says Miyazaki san, senior manager of Engineering Administration Department at NHK. “8K on a single SDI cable simplify our operations and reduce risks inside the OBVAN”.

The VICO-8 can be configured as an encoder or a decoder. As an 8K decoder, it can also be configured to output a down-converted 4K output, thanks to the internal down-scaler available in the TICO compression. It is saving the cost of heavy 8K professional displays, when 4K display are available to monitor the 8K signal..

All of this would not have been possible without intoPIX TICO supporting resolution up to 7680×4320 pixels, while keeping all its famous performances” says Yoshizu Taira, OEM Manager at Village Island. “Our customers are just expecting to work with raw quality and near-to-zero delay, and only TICO would bring this reality on affordable FGPA”.

TICO technology eases the access to 8K to a wide range of users and applications. 12G-SDI is getting more and more popular in new broadcast infrastructures”, says Jean-Baptiste Lorent, marketing director at intoPIX. He adds: “intoPIX is happy to accelerate the transition to 8K broadcasting, the so-called Super Hi-vision. Enabling 8K on TICO for NHK with the development of new FPGA IP-cores was a natural evolution for us”.
