Chapter 1
Introduction
Welcome to Dolby
®
Digital Cinema!
The Dolby Digital Cinema presentation system is a direct result of Dolby Laboratories’
continued leadership in the development of innovative cinema technologies. Dolby Digital
Cinema provides a flexible system designed to deliver the best possible cinema experience.
In creating this new system, Dolby utilized its vast experience with production and
exhibition, processing systems, and cinema equipment design. Designed from the ground
up, Dolby Digital Cinema serves the exhibition and production communities equally well,
ensuring that the cinema continues to provide the optimum environment for experiencing
the director’s vision. Building on the company’s unique experience as a pioneer in
entertainment technologies and as a leading supplier of cinema audio equipment, Dolby
Digital Cinema provides reliability, flexibility of operation, adaptability for the future, and
system security. Containing both image and sound components, it incorporates the open
standards specified by Digital Cinema Initiatives (DCI).
The Dolby Digital Cinema presentation system consists of the following components:
• Dolby Show Store, high reliability storage
• Dolby Show Player, secure high ‐ quality digital content decoder
• Dolby NA10 Network Automation Interface
• Dolby DMA8Plus Digital Media Adapter and a cinema sound processor or a Dolby
CP650 Digital Cinema Processor
• Dolby Show Manager theatre management software
• 1000BASE ‐ T Ethernet Switches
• User ‐ provided USB keyboard, USB mouse, and computer monitor
(minimum 1,024 × 768 resolution at 60 Hz)
• User ‐ provided digital cinema projector (can also include a film projector)
1.1 Dolby Digital Cinema Network Overview
Figure 1 ‐ 1 shows a typical Dolby Digital Cinema network. In this example, a Dolby Show
Store in auditorium 1 sends encrypted and encoded content to a Dolby Show Player in the
same auditorium. The Dolby Show Manager software monitors and controls the entire
theatre complex (which can include both digital and film projectors, as shown in
Figure 1 ‐ 1).
When Dolby Digital Cinema systems are installed in other auditoriums, the Show Store in
each auditorium can send content to its local Show Player and run the Show Manager
Client (along with properly equipped remote PCs). However, only one Show Store (in this
example, the Show Store in auditorium 1) can function as the Show Manager Server for the
entire theatre complex. At the time of the installation, one of the Show Stores is designated
as the Show Manager Server by a Dolby authorized technician. The Dolby Digital Cinema
presentation system can function with or without the Dolby Show Manager software.
