DGy Multicast Video Server

Graphics Resolution – JPEG 2000 Compression

The DGy Multicast Video Server (MVS) is a fully integrated, custom configurable system for recording, storing, and distributing multiple channels of high resolution, real-time imagery using the JPEG2000 compression standard. It is part of RGB Spectrum’s extensive line of JPEG2000 recording and streaming solutions supporting resolutions up to 1600 x 1200.

The Multicast Video Server offers the powerful capability to record and store multiple channels while simultaneously streaming the same imagery out to remote locations. It is used with RGB Spectrum’s DGy codecs for encoding at origination and decoding at destination points to provide a complete solution.

The Multicast Video Server provides a centralized mechanism for handling incoming streams to be recorded and stored while simultaneously streaming out the same or pre-recorded imagery for remote viewing, supporting 4 to 24 simultaneous streams in any combination of incoming and outgoing streams.

In a simulator application, for example, the instructor can view critical data as seen by the pilot on a real-time basis while the same information is being recorded on the MVS. Observers in remote locations can view the same data, in real time or afterward. The MVS offers a complete solution for even the most complex simulator. For example, while a simulation is being recorded and streamed to an Instructor’s Operating Station, previously recorded simulations can be recalled and streamed out to a debriefing room.

The Multicast Video Server provides innovative interframe compression support to minimize network bandwidth requirements. Interframe compression allows the user to increase compression levels to reduce streaming bandwidth. Interframe compression functions by analyzing interframe redundancy and content changes. It exploits the similarities between successive frames, known as temporal redundancy, to reduce the volume of data required in a sequence of frames. The result is reduced data bandwidth during transmission.

Advanced features include event marking, random access, time code synchronization, variable speed playback, and jog/shuttle frame advance/reverse. The Multicast Video Server’s combination of superb image quality, rich feature set, and outstanding performance make it the ideal solution for demanding, mission-critical applications.

RGB Spectrum’s recording and streaming technology has become the de facto standard in mission-critical applications such as simulation, command-and-control, emergency operations centers, missile testing, security, and telemetry. Noteworthy installations include the F-35 Lightning III Joint Strike Fighter simulator program, the U.S. Army Future Combat Systems program, the U.S. Army Space and Strategic Defense Command, the U.S. Army Operational Test Command, and deployments on the U.S. Navy destroyer fleet, the Canada Navy frigate fleet, and the U.S. Missile Defense Agency.
