NAB2015: Sony launches 4K system camera

NAB2015: Sony launches 4K system camera

Sony is claiming a first in the world of 4K system cameras with the launch of the HDC-4300.

The launch of a 4K B4 mount camera for live production was a widely expected move by Sony which didn’t disappoint with the HDC-4300 topping a wide ranging bill of new announcements at NAB.

Sony described the HDC-4300 as the first 4K system camera with three authentic 4K 2/3 inch image sensors.

Designed for use with high magnification wide zoom range lenses currently employed by HD 2/3-inch system cameras, the HDC-4300 is capable of the depth of focus required for sports broadcasting.

The camera also supports the same B4-mount lenses and the same control surfaces as Sony’s industry leading HDC-2000 series cameras.

The camera is capable of 4K/HD operation, and also offers variable speed options up to 8x with a paid for software upgrade.

The camera will support the next-generation ITU-R BT.2020 broadcast standard’s widened color space.

High dynamic range

In a series of other announcements Sony said that it was to focus on developing high dynamic range TV to best show off 4K images.

Sony is demonstrating its HDR technology on its stand this year as well as planning to develop a domestic television with high dynamic range capabilities this year.

The high dynamic range mastering process consists of a combination of enhancements to brightness, contrast, colour gamut and resolution.

High dynamic range televisions are able to show the quality of 4K output from cameras much better than standard 4K TVs.

IP-based production 

Sony is also demonstrating its 4K-ready, IP-based production switcher using the Networked Media Interface at NAB 2015.

The solution is centred around a 4K-ready, IP-networked live production switcher, and the exhibit includes mock-ups of a 4K/HD baseband processor and a 4K/HD Video server – currently in development – that will be necessary for achieving complete live production solutions.

The system uses a single 40 GbE fiber-optic Ethernet cable transmitting multiple 4K and HD video streams from a camera area at Sony’s booth. 

The system includes a hitless failover feature that ensures signal interruption is avoided in the event of IP switch failure.

Sony said that its IP Live Production System is now supported by 30 industry-leading companies.

The new AV over IP interface delivers low latency and noise-free switching of HD and 4K video, audio, and metadata, as part of an IP-based network.

As part of raft of NAB announcements Sony also revealed a new YouTube channel dedicated to 4K content.
