The Indigo2 IMPACT Compression motion JPEG option card from Silicon Graphics provides two independent channels of full-resolution, full-motion, real-time video compression and decompression for the Indigo2 IMPACT family of desktop workstations. Combined with sophisticated third-party software applications, this option works alone or with the Indigo2 IMPACT Video serial digital video I/O option card to form a powerful tool for video production, digital video distribution, motion video analysis, and video-based training.
Indigo2 IMPACT Compression overcomes the obstacle presented by the colossal data streams of video sources. It is a vital component of the digital studio of the twenty-first century, combining leading computer graphics, image processing, digital video, and high-quality video in an efficient, desktop environment. With this option, you can tap the power of the digital studio without sacrificing image size, frame rate, or storage capacity.
Utilizing the expansive bandwidth of your Indigo2 IMPACT workstation, this option provides the horsepower for processing two channels of JPEG data simultaneously. Encode or decode two channels in any combination. The advanced design of Indigo2 IMPACT enables capture and playback of full-resolution full-motion video, compressed as low as 2:1.
Indigo2 IMPACT Compression provides real-time color space conversion and image scaling when decompressing to main memory - crucial for flexible viewing of video clips and processing sophisticated transitions and effects.
Freedom of Choice
The excessive data rates produced by video sources force difficult decisions. Sometimes image quality rates highest priority. At other times, considerations for storage size and transmission bandwidth are more important. Flexible software controls support settings for constant image quality or constant bit rate. When image quality is your primary concern, you can capture video uncompressed, eliminating the possibility of artifacts.
Stand-Alone or with Indigo2 IMPACT Video
Highly integrated Indigo2 IMPACT Compression provides everything required for most video applications: video I/O (composite or S-video) with genlock, capture, compression/decompression, and playback.
It is compatible with all Indigo2 IMPACT graphics solutions, and is ideal for collaboration, previewing animations, and non-linear editing.
For applications that demand broadcast quality, Indigo2 IMPACT Compression combines with Indigo2 IMPACT Video. The two cards are then linked by a dedicated data path, ensuring the real-time passage of digital video data and allowing compressed digital video streams to be used as elements in sophisticated effects such as real-time keying, blending, and video texture mapping. This complete digital video solution provides ideal environment for broadcast-quality nonlinear editing, spot playback, and still storage.
Digital Media Libraries
Providing a reliable foundation for syn- chronizing audio and video data streams, digital media development libraries (video library, compression library, movie library, and audio library) provide software devel- opers complete control of the this options capabilities.
