It is often needed to use specific extenders that also will often leverage CAT5 or CAT 6 Ethernet cables. Compared to SDI and Ethernet however, HDMI does not provide sufficient cable length. The new Ultra High Speed HDMI (or HDMI 2.1) extends the original 18Gbps bandwidth of HDMI 2.0 to the exact 48Gbps necessary for 8K 60p video transport. A technology that is currently extremely costly, and thereby eliminates a major advantage of using COTS IP products. Working with a modern IP based infrastructure, the 48Gbps of an 8K stream however, would force implementers to settle on the usage of 100Gb Ethernet connections. Use of standard IT technologies, building an agile, flexible, reconfigurable and scalable workflow, dealing agnostically with a multiplicity of formats with a ubiquitous accessibility – all these are advantages of IP. Ultimately, a very complex setup that can easily lead to unstable operation. This in turn increases the number of I/O interfaces and cross points in a matrix switcher, making it necessary to use an 80x80 matrix switcher. In an SDI setting, 8K 60P, 4:2:2, 10bit would require the distribution of a single video stream over 16 3G-SDI cables or 4x 12G-SDI cables. using expensive, high-bandwidth cables.īoth would lead to vast investments and an additional rise in power consumption.Įxisting solutions for carrying 8K uncompressed.Retaining the current approach of uncompressed video, the only options are: The table below shows the required bandwidth arriving with a transition to 8K and higher quality video. Moving to UHDTV2 requires an expensive hardware upgrade, a heavy renewal of infrastructure and will increase the power consumption notably. Uncompressed storage and transmission becomes unaffordable and unmanageable within systems and infrastructures. With 8K on the verge, a future-proof solution has to be found. That’s 8K.Ĭurrently the industry is struggling to upgrade their infrastructures to handle 4K video, which at 60fps, 4:2:2,10bit requires nearly 12Gbps. At 60 frames per second that leads to 120 billion pixel to be transported, managed and stored every minute. Doubling the height and width of 4K again, total pixels reach a whooping 33.2 million pixel per image. Increasing your resolution from HD (1920x1080) to 4K (3840x2160) already quadruples the total pixel count to 8,294,400 pixels. Together with other rapid improvements in video quality such as HDR and higher frame rates, data amounts are skyrocketing. Taking a peek into the future, Japan’s national TV “NHK” has even announced to broadcast the full Olympic games on home turf in 2020 in glorious 8K. Display and projection manufacturers are already presenting their first 8K-capable products and the 2018 Winter Olympics were partly filmed in this currently largest video resolution format. With HD omnipresent and 4K seemingly still in its early stages, an even higher resolution, namely 8K (or UHDTV2) is arising.
