International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / Modern High Density Digital Recorders (HDDR) are ideal devices for the storage of large
amounts of digital and/or wideband analog data. Ruggedized versions of these recorders
are currently available and are supporting many military and commercial flight test
applications. However, in certain cases, the storage format becomes very critical, e.g.,
when a large number of data types are involved, or when channel-to-channel correlation is
critical, or when the original data source must be accurately recreated during post mission
analysis. A properly designed storage format will not only preserve data quality, but will
yield the maximum storage capacity and record time for any given recorder family or data
type.
This paper describes a multiplex/demultiplex technique that formats multiple high speed
data sources into a single, common format for recording. The method is compatible with
many popular commercial recorder standards such as DCRsi, VLDS, and DLT. Types of
input data typically include PCM, wideband analog data, video, aircraft data buses,
avionics, voice, time code, and many others. The described method preserves tight data
correlation with minimal data overhead.
The described technique supports full reconstruction of the original input signals during
data playback. Output data correlation across channels is preserved for all types of data
inputs. Simultaneous real-time data recording and reconstruction are also supported.
