Dolby Cinema

Dolby Cinema is a premium cinema concept created by Dolby Laboratories that combines Dolby proprietary technologies such as Dolby Vision, Dolby Atmos, signature entrance and intrinsic design features. The technology is expected to compete with other formats such as IMAX and exhibitors own premium large format packages.

The first installations featuring Dolby Cinema were JT (now Vue) Bioscopen Cinema in Eindhoven, Netherlands on 18 December 2014; followed by Cinesa La Maquinista in Barcelona, Spain. Dolby Laboratories has partner contracts with Cinesa, Vue Cinemas, AMC Theatres,Cineplexx Cinemas, Wanda Cinemas and Jackie Chan Cinema to install Dolby Cinemas.

Dolby Vision is an in-house projection system developed by Dolby Laboratories in conjunction with Christie Digital. The system consists of dual Christie 4K 6P (primary) modular laser projectors featuring a customized design to allow for unique light path. The system is capable of delivering up to 14 foot-lambert on unity-gain matte-white screens for 3D (and up to 31 foot-lambert for 2D), a substantial improvement on current generation 3D systems which deliver in the range of 3 to 4 foot-lambert for 3D. The result is improved brightness, color and contrast compared to traditional xenon projectors. The first theatres temporarily used off the shelf dual Christie 4K laser projectors until the Dolby Vision-capable ones were shipped out in spring 2015.

Dolby 3D uses spectrum separation, where the two projectors function in stacked operation and each projector emits slightly different wavelength of red, green and blue primary. There is no polarization present on the projector and the 3D spectacles have notch filters that block the primaries used by the projector that projects the image intended for the other eye.

Dolby Vision is able to display the following resolution / frame rate combinations:

Although the twin projectors are capable of displaying the 7,500:1 contrast ratio defined by the DCI fixed luminance gamma function; for movies not graded with Dolby Vision, the projectors are limited to 5,000:1 contrast ratio.

Dolby Atmos is an object and channel based hybrid sound format developed by Dolby Laboratories. The system is capable of reproducing ten bed channels and 128 objects, through 64 individual speakers in order to pan sound around and through the auditorium. This allows recreation of effects such as thunder and flyover using the ceiling channels as well as pin point effects such as bumps or bullets using objects.
