SR-1000 Standalone Integrated Media Block™

Standalone Integrated
Media Block™

The time-tested IMB with proven consistent performance


GDC 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 service, GDC is recognized globally as a leader of 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.

With its future-proof flexible architecture, the SR-1000 offers several affordable options, including 4K, a built-in diskless CineCache™ 2TB and a built-in 5.1/7.1 cinema audio processor. In addition, there are two other optional upgrades: (i) a built-in 15.1 cinema audio processor is available to replace an external cinema processor for a DTS:X™ installation; and (ii) 16-/24-channel DTS:X decoding capability to feature DTS:X Immersive Audio Solution.

The SR-1000 supports playback of SMPTE and Interop digital cinema packages (DCP) at bit rates up to 500 Mbps1; its DTS:X solution supports SMPTE’s ST 2098-2 immersive audio bitstream (IAB) standard delivering a single interoperable audio format for theatrical distribution.

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 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 in a 3D dual projector system
    CineCache is a superior technology providing very high-reliability playback of 3D content at 120 fps-per-eye in a dual projector system.

^ 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 Audio Solutions

The SR-1000 offers various built-in audio options of 5.1/7.1/15.1 cinema audio processor and 16-/24-channel DTS:X decoder. DTS:X immersive audio solutions provide full support of SMPTE’s ST 2098-2 immersive audio bitstream (IAB) standard, representing a major milestone to deliver a single interoperable audio format. Supporting SMPTE’s IAB will bring even more immersive content to the big DTS:X screens worldwide – exactly as the filmmakers intended.
