NHK is also forging ahead with its “Super Hi-Vision,” or 8k, format, which measures 7,680 by 4,320 pixels. TV manufactures are beginning to produce sets that can show 4k and 8k, named after their horizontal resolution, but content is still scarce. NHK, which aims to launch a broadcast service in Japan by 2020, is working on developing cameras that can shoot in the format and are easy to use.
Early versions were bulky devices the size of small cannons, but the company’s latest creation is on par with standard TV cameras, although it has a slightly lower resolution than true 8k. The massive data requirements are also a challenge, as cameras record at nearly 72 Gbps. To support its latest camera, NHK has designed a small computer with 1.5TB of flash storage, although that can only hold 50 minutes of footage.
