The fireware facilities designed by Reliable Digital Solutions and iVAST (USA) companies can become the components of streaming integrated system, composed on end-to-end principle, comprising all components such as devices in the range from multi-format coding of information and its spreading on networks up to acceptance and decoding in required TV standard.

These facilities vastly increase the possibilities of traditional video systems. They allow joining a live web-stream, the archiving, transcoding and interactiveness with existing TV or information system. Their particularity is that information can be encoded in real-time practically in any existed format: MPEG-1/-2/-4, Windows Media, Quicktime, Real Media, Divx, etc. Such multi-formatness allows to increase the user network geographically, and realization of the most latest technologies of signal and coding processing makes a content cheaper and technically available for user, since allows to get effectively compressed digital videosignal with synchronous audio in any stream in the range from 40 Kbit/s to 50 Mbit/s. Thereby it is possible greatly raise the transmission capacity of networks in contrast with traditional ways of the video- and audio signal processing, providing herewith a similar or higher quality.

Total features of the mechanism of the media information processing

The core of all coding devices provided by Reliable Digital Solutions company is a mechanism of the media information processing (MIP). Streampress Encodecoder can be provided by one or two MIP-channel, which enable to process 1-2 video streams and up to 8 audio streams in realtime simultaneously. Each MIP-channel allows, for instance, to execute the recovering of progressive scanning adapted to motion (the mechanism of the step-by-step, or incremental, processing of movement), the correct recognition of TV-movie materials, as well as the thriaxial noise suppression adapted to motion.

Under incremental motion processing (Motion Adaptive De-interlacing) each pixel is processed independently, and created picture is got the highest quality. The areas with absence of the motion are statically separated, but areas with discovered motion are processed by individual technology of filtering, providing high-quality picture in progressive scanning. This is an extended process of the video processing allows to perfect the inferior videosignals and optimize the high-quality signals. As a result the datastreams of higher resolution are got. The Streampress Encode units are provided by the high effective algorithms for noise processing. For instance, algorithm of thriaxial noise suppression is based on pixel agglomeration of information from a great many video pictures to solve what processing volume is needed for each pixel in final frame. Since each pixel is computed individually, such noise suppression provides the final result with greatly smaller amount of motion blurs, than under any other processing mode.

The standard audio possibility of these devices is the support of eight 24-bit audio channels. Each channel has seven-band parametric equaliser, allowing varying the levels and frequencies of the processing. Control of compression and dynamic range extension on each stereopair allows obtaining the loud and clear voice.

The main technical features of Streampress Encode Total series are as the following.
