//    Description : Peer to Peer Video Conferencing over the LAN.
//	  Author      :	Nagareshwar Y Talekar ( [e-mail])
//    Date        : 15-6-2004.
//
//    This is the modified version of tmndecode (H.263 decoder) 
//    written by Karl & Robert.It was in ANSI C. I have converted into C++
//    so that it can be integrated into any windows application. I have 
//    removed some of the files which had display and file storing 
//    functions.I have removed the unnecessary code and also added some
//    new files..
//	  Original library dealt with files. Input & Output , both were files.
//    I have done some major changes so that it can be used for real time 
//    decoding process. Now one can use this library for decoding H263 frames. 
//
//
//    File description : 
//    Name    : Tmndec.h
//    Details : Main entry point for decoder.
//
//    Usage : 
//			1) InitH263Decoder
//			2) Invoke DecompressFrame with parameters
//			      compressed data and output data pointers.
//			  Note > Output data must be large enough to hold RGB data.
//                 > Change the DecompressFrame function if you want 
//					 output in YUV420 format only. Just comment out conversion routine
//          3) Repeat the step 2 for each compressed frame , for exit do 4
//			4) ExitH263Decoder  .
