2. Parallel Video Compression System For Satellites Performed by: Dmitry Sezganov, Vitaly Spector Instructor: Stas Lapchev, Artyom Borzin In Cooperation with:

3. Abstract  Military satellites gather information – Photography.  Higher resolution means more details – info worth more.  Solution – lossless image compression: JPEG2000 algorithm.  Continuous input DataStream – Real time compression. Project Purpose: Design and implementation of prototype compression system for satellite images.

4. System JPEG2000Compression System System Extractor Transmitter Receiver Our Project Satellite Earth Station

5. System Input DataStream 8 km/s 2.5km  The rate for one sensor only.  There are many sensors. 16,000 lines/s 4pix/m² X 2.5km X 8km/s = 80Mpixel/s 5000pix Input pixel data rate: 12 bit/pix X 80Mpixel/s ≈ 1Gbit/s Input bit rate: The system input data rate - Multi Gbit rates!

6. Main Idea  Single chip solution for narrow region Real Time Compression.  Parallel Compression – n must be minimal. N 5000/n5000 pixels5000/n 16,000 lines/sec
