VIDEO COMPRESSION DECK FOR A MODULAR FLIGHT PCM ENCODER SYSTEM

Gammill, Troy, Stoner, Mark 10 1900 (has links)
International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Overview of video compression modules developed and flown as part of PSL’s flight-proven family of modular PCM components. Wavelet based video compression deck is compatible with PCM Encoder modules, allowing video to be included in instrumentation data stream. Video compression modules allow the user to select video frame rate and video quality, supports 8-16 bits/word, and non-symmetrical PCM matrices. Video Compression and formatting is achieved with a wavelet compression IC and specialized DSP code. Video output is achieved with PSL PCM Decommutator and Video Decompression Module.

A Telemetry System with Fibre Transmission

Qishan, Zhang, Xianliang, LI, Jun, Zhang 10 1900 (has links)
International Telemetering Conference Proceedings / October 17-20, 1994 / Town & Country Hotel and Conference Center, San Diego, California / It is known that a PCM telemetry system features with good accuracy, great dynamic range, and low noise. And when more than fourteen data channels are required, the PCM is generally the best choice. The paper describes the general ideas involved in developing a PCM telemetry system with fibre transmission.
