State-of-the-Art Technology

Avery Movie Screen

The Avery’s movie screen is a Spectral 240, made by Harkness Screens. The Spectral 240 is a 3D silver screen with an excellent performance history. The base material of the screen surface is coated in silver aluminum flake. This creates “high gain characteristics, strong signal-to-noise ratios, generous viewing angles and excellent color temperature.”

The final product is “a special ultra-high brightness silver screen that gives excellent performance with ‘passive’ 3D applications using polarized light, such as RealD.”  At the same time, it performs well with standard film presentations.

Digital Projector, Data Storage

The Avery’s digital cinema projector is the NC2000C model made by NEC. The projector uses DLP Cinema technology from Texas Instruments and “delivers exceptional image quality, brightness, resolution, contrast and colorimetry.”  The digital cinema projector also allows 3D presentations to be shown using a single projector; it also supports the needs of all major suppliers of 3D movies.

The advanced DLP Cinema® light engine provides contrast ratios up to 2200:1, which enable better reproduction of detail in dark scenes. Images are projected using a 3-chip digital micro-mirror device, or DMD, reflection method. It is capable of projecting 17,000 lumens (when using a 4.0 kW high-efficiency xenon lamp bulb). It projects an image of 2048 x 1080 pixels, also referred to as 2K formatting. With the installation of Doremi’s Integrated Media Block (IMB), the projector has been upgraded and made compatible with 4K technology.

While the industry standard is to film motion pictures using a frame rate, or frame frequency, of 24 frames per second, the Avery’s projector supports a high frame rate of 48 fps which reduces motion blur and flicker to create a greater sense of reality.  A liquid cooling system inside the projector helps with dissipating the heat created by the system. The projector itself is relatively quiet, emitting less than 62 dB when operational.

The IMB/ShowVault by Doremi is a dedicated storage server is needed for downloading and saving the digital content. ShowVault is capable of playing JPEG2000 digital movies that conform to DCI specifications. It was specifically designed to interface and partner with Doremi’s IMB (Integrated Media Block), which is installed inside the digital projector.  The IMB uses 4K media block technology, which makes playback of 4K resolutions possible.

ShowVault loads digital content from the dedicated storage server via Ethernet, USB 2.0 or CRU/ESata. It electronically processes files to the IMB via an external PCI Express cable. ShowVault also allows theater operators to pre-program an entire movie schedule, including preview movie trailers, on-screen advertising, feature films and announcements.

Superior Sound Quality

5.1 Surround Sound vs 7.1 Surround Sound

A 5.1 surround sound system uses 6 channels (feeding into 6 speakers) to create surround sound. 7.1 surround sound systems use 8 channels. The two extra channels of sound (and two extra speakers) provide a slightly better audio quality.

7.1 offers greater depth and precision of sound and, particularly for large room applications. 7.1 Surround Sound formats include Dolby TrueHD, DTS-HD Master Audio; whereas 5.1 surround sound -still the more common sound standard — uses the Dolby Digital and DTS formats.. 5.1 surround sound is achieved with Dolby Digital or DTS. DTS uses less compression but is also less common than Dolby Digital. 7.1 surround sound can be achieved using Dolby TrueHD or DTS-HD Master audio. These are considered “lossless audio,” identical to the movie studio’s original.

Invented by Dolby Labs in 1976, the 5.1 Surround Sound application was not used in the cinema until 1992 with the film “Batman Returns.  The first theatrical use of 7.1 Surround Sound  was 2010’s “Toy Story 3.”  Disney has stated it’s intent to use the 8-speaker format for all of its future #D film releases.

5.1 surround sound has 6 sound channels, and so 6 speakers. It includes a center speaker, subwoofer (for low frequency effects, such as explosions), left and right front speakers and left and right rear speakers. As it has a smaller number of speakers and is the industry standard, it is simpler to set up, cheaper and suitable for small or medium-sized rooms.

7.1 surround sound has 8 sound channels. It uses the same 6 speakers as above, plus an extra two side speakers. The extra two speakers add more depth to the surround sound experience. As it uses more speakers, 7.1 surround sound is more expensive and is only suitable for large rooms.

Closed Captioning & Assisted Listening Devices

The  equipment available for use at the Avery Theater is the UPC-21 Infrared Transmitter, and IRC-21 Emitter/Modulator Panel manufactured by USL, Inc.  The infrared emitter simultaneously broadcasts closed caption text and two channels of audio for both the hearing and visually impaired. The system operates at 95 KHz and has low distortion with high sound clarity. The infrared system does not experience radio frequency interference problems or crosstalk.

The Avery’s headsets are the IRH-230 model, also manufactured by USL, Inc.  The over-the-head cordless headset provides two-channel assistive listening that, at the push of a toggle button, runs at either 2.3 or 2.8 MHz.  There are independent volume controls for each ear.

The headsets provide Descriptive Video Service (DVS) for those movies that provide this service in addition to Closed Captioning. DVS technology provides a description of the important visual elements to help provide a more complete understanding of the action and the plot as a whole.  For feature films, the DVS is kept as a separate part of the digital theater system (DTS) soundtrack.

The infrared Closed Captioning System (CCS), also by USL, Inc., is designed to enhance the movie-going experience for hearing impaired patrons. The Avery has personal closed caption devices, the CCR-100 Closed Caption Receiver, which provide a personal captioning experience that is not a distraction for other patrons. The “Seat Mount” display is attached to an adjustable, gooseneck support that rests in the cup-holder of the armrest. Once adjusted, it is a completely hands-free system.

A limited number of each device is available. Patrons wishing to use either the Headphone or Closed Captioning system are advised to arrive early or contact a manager ahead of time about availability.  The USL infrared system is capable of supporting an unlimited number of devices; more units will be added in response to patron demand, and as funding allows.
