COMPRESSION AND DATA ENCODING FOR TRANSMISSION OVER A CHARACTER-BASED PROTOCOL

摘要

ACARS systems 20 and methods 100 for compiling messages includes a processing device 30 configured for mapping eight-bit characters in an eight-bit character stream into a six bit map to create a generally six-bit character stream. The processing device 30 is further configured for encoding the generally six-bit character stream into an eight-bit character stream. Optionally, the processing device 30 includes a look-up table 38 configured to retrieve substituted six-bit characters in response to the presence of the eight-bit character received at a processor.
