SR-1000 Standalone Integrated Media Block™

Standalone Integrated
Media Block™

The time-tested IMB with proven consistent performance


GDC Technology has been at the forefront of cinema technology development since the advent of digital cinema. From a commitment to introducing first-to-market solutions to providing outstanding customer services and technical support, GDC is recognized globally as a leader in integrated media block (IMB) technology. The SR-1000 is the company’s sixth-generation digital cinema media server designed for near-zero maintenance and minimal total cost of ownership.

The SR-1000 supports playback of SMPTE and Interop digital cinema packages (DCP) at bit rates up to 500 Mbps1; its DTS:X™ for IAB Immersive Audio solution supports SMPTE ST 2098-2 immersive audio bitstream (IAB) standard, which was developed to deliver a single interoperable audio format for global theatrical distribution.

With its future-proof flexible architecture, the SR-1000 offers several affordable options, including 4K, a built-in diskless 2TB CineCache™ storage, and a built-in DTS Surround audio processor. In addition, there are more upgrade options targeting DTS:X for IAB installations: (i) a built-in 15.1 cinema audio processor to replace an external cinema processor; (ii) a built-in DTS:X for IAB decoder up to 32-channel and (iii) Audio over Ethernet (AoE) output using AES67 standard.

Key Benefits of SR-1000 Standalone IMB™

High Reliability

With built-in embedded power electronics used in medical and military products, the overall system stability is ensured. The SR-1000 is SGS certified for 100,000 hours Mean Time Between Failures (MTBF).


Compatibility with Series 1, 2, 3 and 4 Projectors

The SR-1000 IMB seamlessly integrates with Series 1, 2, 3 and 4 DLP Cinema® projectors including Barco, Christie and NEC to ensure highly reliable and secure content delivery.


The SR-1000 IMB is designed with diskless CineCache (built-in cache memory) available in 2TB offering key advantages:

  1. Movie ingest in just 30 minutes without interrupting concurrent playback
    CineCache enables incredibly fast content ingest during playback. Content ingest and playback can be performed concurrently without local HDD storage. One average+ movie can be ingested within 30 minutes without interrupting playback. It is no longer necessary to wait for the movie to end to ingest content.
  2. Incredibly fast content transfer across IMBs
    For IMBs with CineCache, content can be copied at lightning speed across IMBs via 1Gbps LAN without any IMB playback interruption. An average+ movie would only take approximately 30 minutes to be transferred between IMBs.
  3. High-speed and high-reliability playback of HFR and HBR contents
    CineCache is a superior technology providing high-reliability playback of content with high frame rates and data rates that are much higher than standard DCPs.

+ The running time of an average movie is between 90 and 120 minutes.

Supports the Playback of Thousands of Movies

Take full advantage of show scheduling with Ultra Storage technology which is capable of storing over 2,000 movies when combined with Cinema Automation CA2.0. The content is available for playback on any screen, any time. You no longer need to ingest content to each screen for playback, saving hours of time for content management operation.

Built-in Wi-Fi with Intuitive Web-based User Interface

Both audio and video features can be configured and controlled remotely through the easy-to-use web-based UI. The web-based UI connected to the SR-1000 built-in Wi-Fi is user-friendly and intuitive. With drag-and-drop, filtering and navigating functions, operators can easily switch between tabs or pages. Other than accessing the UI through a computer or a laptop, wireless access is also enabled by using handheld devices such as a smartphone or a tablet.

Built-in DTS Professional Cinema Audio Options

The SR-1000 offers three built-in cinema audio processing options: 1) DTS Surround, 2) 15.1 cinema audio processor with DTS:X for IAB rendering, or 3) a built-in DTS:X for IAB rendering up to 32 channels. As an option, the DTS Surround Cinema certification program allows a path to future-proof your auditorium to DTS:X for IAB immersive audio. The DTS:X for IAB immersive audio solutions support DTS:X playback and SMPTE ST 2098-2 immersive audio bitstream (IAB) standard, representing a major milestone to deliver a single interoperable audio format. IAB allows motion picture studios to efficiently distribute immersive audio content to the DTS:X screens worldwide-exactly as the filmmakers intended.
