Show Store and Show Player
2.2 Dolby Show Player
The Dolby Show Player receives an encrypted and encoded audio/video bitstream from a
dedicated Dolby Show Store. The Show Player decrypts and decodes the bitstream using
encrypted content keys. The Show Player then reencrypts the video and sends it to the
associated screen’s digital projector. The Show Player also sends eight channels of digital
audio to the associated screen’s Dolby DMA8Plus Digital Media Adapter (or a similarly
equipped Dolby CP650 Cinema Sound Processor).
The Dolby Show Player features a user interface screen that provides easy access to many
of the same functions as the Dolby Show Manager theatre management software.
2.2.1 What’s Included
The Dolby Show Player is housed in a 2 ‐ U (3.5 ‐ inch), 19 ‐ inch rack ‐ mounted custom chassis.
The unit ships with all the required software installed. The system parameters are installed
on one of the Flash ROM drives.
2.2.2 Dolby Show Player Front Panel
The Show Player’s front ‐ panel components include the User Control screen, menu
navigation buttons, an auto on/off button, transport control buttons, an audio/video mute
button, status indicators, and a USB 2.0 port (for use by Dolby authorized technicians only),
