DGy™ JPEG2000 Graphics Codecs

DGy 201HD, 301x, 302x & 501x Codecs

DGy™ JPEG2000 graphics codecs stream, record, and transmit high scan rate images. Models are available in either single channel or dual channel. The DGy sets a new standard in terms of image quality, using JPEG2000 compression to achieve visually lossless digital recording. This wavelet-based codec provides results superior to the more common DCT based compression schemes.

The system streams, captures, compresses, stores, and replays imagery at up to 1600 x 1200 pixel resolution. It supports computer, radar, sonar, FLIR, X-Ray, and HD signals, plus stereo audio. All models can stream or record 1600 x 1200 resolution inputs at up to 20 frames per second or 1280 x 1024 resolution inputs up to 30 fps. In addition, the model 301HD can record to and replay from an external network attached storage device at resolutions up to 1920 x 1200 at 30 fps.

The codecs use external network attached storage, such as a RAID, for centralized recording storage and retrieval. The 501x can record two inputs at half rates, with fully synchronized playback. The 302x offers all of the functionality of the standard model 301x but in a more compact format designed for desktop use.

DGy codecs offer standard JPEG2000, plus interframe compression, making them an ideal solution for streaming graphics across networks where higher compression rates are necessary to avoid overtaxing network bandwidth. The codecs also support file transfer with remote computers or file servers using standard FTP protocol.

The DGy codecs offer an unparalleled feature set. including external time code synchronization (IRIG-B or Network Time Server), event marking, and random access. Multiple DGy units can be interconnected to support simultaneous, synchronized digital recording of multiple channels. Remote playback on a Windows PC is supported using our X.TV® JPEG 2000 plug-in to the standard Windows Media Player. The simultaneous record and replay option allows review of imagery while recording is still in process.

A combination of superb image quality, rich feature set, and outstanding performance make DGy codecs the ideal solution for demanding, mission critical applications.

DGy JPEG2000 graphics codecs can be used in conjunction with our multicast video server (MVS) to provide a complete multi-channel streaming solution in complex environments.
