Back channel:

	Compilation:  type "make" in BackChannel directory.
	Usage: bakchnl pathfile num_of_frames FOV output_bitstream

Forward channel:
	Compilation: change definition of VM_HOME_DIR to vm directory
		in file tools/entropy/huffman.h
		type "make" in vm directory
	Usage: To use encoder, in vm directory, there should be backchannel 
		bitstream generated by bakchnl command (see above) and mesh 
		file (see bigSA128x128.raw)

		vmencode Parameter_File (see parfile.vds)

		To use decoder, 
		
		vmdecode bitstream_file output_file width height pathfile mesh
