International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Various forms of 'lossy' and 'lossless' encoding have been implemented or proposed to allow compression of still and motion picture images, with varying degrees of success which in turn depend on how success is defined. Proponents of various systems claim 'compression ratios' which by their nature defy comparison of one system with another and suggest there actually may be something like a free lunch. This paper compares various compression methods as well as the implications involved in using them and what happens when different systems encounter the problems associated with the uses of the restored picture.

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The ability to acquire real-time video from flight test platforms is becoming an important requirement in many test programs. Video is often required to give the flight test engineers a view of critical events during a test such as instrumentation performance or weapons separation. Digital video systems are required because they allow encryption of the video information during transmission. This paper describes a Digital Video Telemetry System that uses improved video compression techniques which typically offer at least a 10:1 improvement in image quality over currently used techniques. This improvement is the result of inter-frame coding and motion compensation which other systems do not use. Better quality video at the same bit rate, or the same quality video at a lower bit rate is achieved. The Digital Video Telemetry System also provides for multiplexing the video information with other telemetered data prior to encryption.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Conventional video image transmission requires large data bandwidths, whether the signals are transmitted in analog or digital form. Many applications are limited to bandwidths that will not support image transmission unless high compression ratios are employed. Video compression techniques based on wavelet functions provide high data compression while preserving image quality, but are computationally demanding. Recently available high-integration devices that utilize wavelet basis functions for video compression have made possible low-cost high-performance video compression systems. Image data is more useful when provided with other data such as position information, telemetry, or other user data. This paper describes the technology, features, and limitations of a versatile low data rate system incorporating compressed video data.

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / In this paper, we present an efficient real-time implementation technique for Motion-JPEG2000 video compression and its reconstruction used for a real-time Airborne Video Telemetry System. we utilize Motion JPEG2000 and 256-channel PCM Encoder was used for source coding in the developed system. Especially, in multiplexing and demultiplexing PCM encoded data, we use the continuous bit-stream format of the PCM encoded data so that any de-commutator can use it directly, after demultiplexing. Experimental results show that our proposed technique is a practical and an efficient DSP solution.
