AEC

NAME

aec − compress or expand files

aec [−3] [−b BYTES] [−d] [−j SAMPLES] [−m] [−n BITS] [−N] [−p] [−r BLOCKS] [−s] [−t] infile outfile

Aec performs lossless compression and decompression with Golomb-Rice coding as defined in the Space Data System Standard documents 121.0-B-2.

−3

24 bit samples are stored in 3 bytes

−b BYTES

internal buffer size in bytes

−d

decompress infile; if option −d is not used then compress infile

−j SAMPLES

block size in samples

−m

samples are MSB first; default is LSB first

−n BITS

bits per sample

	−N		disable pre/post processing
	−p		pad RSI to byte boundary

−r BLOCKS

reference sample interval in blocks

	−s		samples are signed; default is unsigned
	−t		use restricted set of code options
