“…The first live transmission was demonstrated at IBC 2008, and in 2012 the first UHDTV consumer products became available. 2013 was the year in which some broadcasters started to use High Efficiency Video Coding (HEVC) for transmission [3]. Almost all UHDTV sets have 3D capabilities, and content production started on a larger scale not only for UHDTV, but also for 3D UHDTV.…”

3D UHDTV contents production with 2/3-inch sensor cameras

Most UHDTV content is presently created using single large CMOS sensor cameras as opposed to 2/3-inch small sensor cameras, which is the standard for HD content. The consequence is a technical incompatibility that does not only affect the lenses and accessories of these cameras, but also the content creation process in 2D and 3D. While UHDTV is generally acclaimed for its superior image quality, the large sensors have introduced new constraints in the filming process. The camera sizes and lens dimensions have also introduced new obstacles for their use in 3D UHDTV production. The recent availability of UHDTV broadcast cameras with traditional 2/3-inch sensors can improve the transition towards UHDTV content creation. The following article will evaluate differences between the large-sensor UHDTV cameras and the 2/3-inch 3 CMOS solution and address 3D-specific considerations, such as possible artifacts like chromatic aberration and diffraction, which can occur when mixing HD and UHD equipment. The article will further present a workflow with solutions for shooting 3D UHDTV content on the basis of the Grass Valley LDX4K compact camera, which is the first available UHDTV camera with 2/3-inch UHDTV broadcast technology.
