.TH GYDECODE 1 "QCCPACK" "".SH NAMEgydecode \- 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 gydecodedecodes 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 gydecodeperforms VQ-index lookup of the indices in.I channelfilewhile updating the VQ codebook as dictated by.IR sideinfofile ..B gydecodestarts decoding using the initial codebook specifiedby.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..SH "SEE ALSO".BR gyencode (1),.BR avqrate (1),.BR QccPackAVQ (3),.BR QccPack (3)A.
