tmndecode			      =========		      Version 1.7, May 7, 1996	  (C) Telenor R&D, Karl Olav Lillevold <kol@nta.no>tmndecode is free software. See the file COPYING for copying conditions.tmndecode is a decoder and player for H.263 bitstreams. It can displaythe decoded sequence at 8, 16, and 24(32) bits colordepths in both X11and Microsoft Win32 window systems. For QCIF resolutions the displayspeed should be real-time on most systems.tmndecode was originally based on mpeg2decode and mpeg2play. What isleft is the file organization, the io-routines and some of thedisplay- routines for X11.  mpeg2decode is (C) 1994, MPEG SoftwareSimulation Group and mpeg2play is (C) Stefan Eckart,stefan@lis.e-technik.tu-muenchen.de.  Most of the 16 and 24(32) bitcolordepth routines are from mpeg_play, which is (C) 1995 Erik Corry.Compatibility=============This H.263 decoder is believed to be compatible with the descriptionof the H.263 standard as of May 7, 1996. All the the negotiable codingmodes described in the standard are implemented: the UnrestrictedMotion Vector mode, the Syntax-based Arithmetic Coding mode, theAdvanced Prediction mode and the PB-frames mode. See the CHANGES filefor changes since the last version. See the TODO file for items notincluded in this version.An H.263 (TMN5) compatible encoder with the same modes (tmn) and somesample bitstreams are also available from Telenor's ftp sitebonde.nta.no in /pub/tmn/software/.TMN was the Test Model Near-term for the ITU-LBC group working towardsa standard for video telephony on normal analogue telephone lines.This standard is called H.263.Installation============This software should work on most 32 bit systems. I have tested itwith OSF/1, SunOS-4.1.3, Linux, and Windows 95/NT. Display works withboth X11 and Windows. Use Makefile to compile under Unix. Windows: The enclosed makefile tmndec.mak can be used with VisualC++. If you use another compiler or makefile, define WINDOWS andUSE_TIME. If you can't get it to compile with a different Win32compiler, I will probably not be able to help you.Bitstreams encoded with older version than 1.6 of our encoder are nolonger decodable. Usage=====Usage:   tmndec {options} bitstream {outputfilename%d}Options:-vn  verbose output (n: level)Instructs tmndecode to generate informative output about the sequenceto stdout. Increasing level (-v1, -v2) results in more detailed output.-on output format               n=0 : YUV              n=1 : SIF              n=2 : TGA              n=3 : PPM              n=4 : X11 Display              n=5 : YUV concatenated              n=6 : Windows 95/NT display    Use -o5 for the same format as the Telenor encoder uses.    You have to choose one output format!-q  disable warnings to stderr-r  use double precision IDCT-t  enable low level tracing-x  interpolate pictures to double size before display    (on Windows, maximize display window to get double size display)-fn  frame rate in frames per second     n=0  : as fast as possible     n=99 : read frame rate from bitstream (default)-l  loop sequence    Setting this flag results in repeated display of the sequence.Contact me at kol@nta.no if you have trouble using tmndecode or findany bugs.

I changedthis with code for both 16 and 24 (32) bits written by Erik Corry, andadded my own routine for 24 bits packed mode. Juha then suggestedimprovements and helped me test the new modes.Patrick Mulroy and Wayne Ellis at BT Labs did most of the SAC workincluded in version 1.4.Anurag Bist at Rockwell had the idea and implementation outline fordouble sized display.Michael Third at Intel Architecture Labs wrote the first version ofthe Windows display running in a separate thread.--Karl Olav Lillevold  <kol@nta.no>   -->  http://www.nta.no/brukere/kol/ Digital Video Coding [H.263/MPEG-4] -->  http://www.nta.no/brukere/DVC/at Telenor R&D
