                             =========

                  TML Version 2.0, January 13, 2000

This package include DOS executable codec of the H.26L Test Model Long Term Number 2 (TML-2) and anchor 
bitsteams generated by the encoder. These might be decoded by the decoder. The included log file log_all.dat
containing output from simulations and is produced following the document "Recommended Simulation Conditions 
for H.26L" (doc.no q15i62).  

Usage encoder :
===============
From DOS command prompt:
lencod <lencod.dat>
For the format of the configuration file, see description in lencod.dat.
During execution, the encoder will produce a log file, a status file and a H.26L bitstream.

   
Usage decoder :
===============
From DOS command prompt:
Decoder :   ldecod <ldecod.dat>
For the format of the configuration file, see description in ldecod.dat.
During execution, the encoder will produce a log file and a decoded sequence.

TML2 description:
=====================
The H.26L Test Model Long Term Number 2 (TML-2) is described in document Q15-I-57, output from Red Bank.


Discrepancies between TML description and software
================================================
- The RD constrained quantization not implemented in this SW, represent a PSNR loss of about 0.25 db.
- The bitstream are not fully compatible with the TML2 description, represent no PSNR discrepancy.
