.TH GYDECODE 1 "QCCPACK" ""
.SH NAME
gydecode \- decoder for the Gersho-Yano AVQ algorithm
.SH SYNOPSIS
.B gydecode
.I channelfile
.I sideinfofile
.I codebook
.I codebook\_coder
.I datfile
.SH DESCRIPTION
.LP
.B gydecode
decodes a channel,
.I channelfile
(CHN format), and side information,
.I sideinfofile
(SID format), both produced by
.BR gyencode ,
and writes the resulting output data to
.IR datfile .
That is, 
.B gydecode
performs VQ-index lookup of the indices in
.I channelfile
while updating the VQ codebook as dictated by
.IR sideinfofile .
.B gydecode
starts decoding using the initial codebook specified
by
.I codebook
(which should be the same initial codebook originally used by
.BR gyencode ).
.I codebook\_coder
(SQ format) gives the scalar quantizer used to decode the side information.
