$Revision: 11 $
* Purpose:	
*
*			Global symbols needed to build the Video Lab software.
*			All Analog Devices modules and include files expect the
*			symbols and typedefs herein, and may fail to compile if any
*			such items are missing.
*			
* Notes:

$History: GLOBSYM.H $
 * 
 * *****************  Version 11  *****************
 * User: Dstarr       Date: 6/30/97    Time: 9:52a
 * Updated in $/601test
 * Add #define SQUARE_PIXEL  as a bit passed to various init routines
 * telling them to set up for square pixel operation. Note. the SAA7111
 * can't do square pixel, so you either have to switch over to a SAA7110
 * or just do square pixel decode.
 * 
 * *****************  Version 1  *****************
 * User: Stevel       Date: 6/09/97    Time: 4:54p
 * Created in $/601cman/sqpix
 * 
 * *****************  Version 10  *****************
 * User: Dstarr       Date: 10/03/96   Time: 3:34p
 * Updated in $/601test
 * #define DSP_BWC as a bit flag to enable a DSP on the serial port to do
 * the bin width calculations.
 * 
 * *****************  Version 9  *****************
 * User: Dstarr       Date: 8/07/96    Time: 1:28p
 * Updated in $/601cman
 * #define PHILLIPS
 * 
 * *****************  Version 8  *****************
 * User: Stevel       Date: 7/25/96    Time: 8:13p
 * Updated in $/601cman
 * Add two constant for YC or RGB video output.
 * 
 * *****************  Version 7  *****************
 * User: Stevel       Date: 7/06/96    Time: 2:37p
 * Updated in $/601rpman/ihbmbwc
 * Add 2 new symbol.
 * 
 * *****************  Version 6  *****************
 * User: Stevel       Date: 6/23/96    Time: 9:28p
 * Updated in $/601cman
 * Add changes to support run time Bin Width Calculation.
 * 
 * *****************  Version 5  *****************
 * User: Dstarr       Date: 6/14/96    Time: 10:03a
 * Updated in $/601test
 * Add #define ASAP_FIFO  0xF1
 * 
 * *****************  Version 4  *****************
 * User: Dstarr       Date: 6/07/96    Time: 1:54p
 * Updated in $/601test
 * #define STD_FIFO_THRES 
 * 
 * *****************  Version 3  *****************
 * User: Dstarr       Date: 5/02/96    Time: 2:03p
 * Updated in $/601cman
 * Spell DIG_VIDEO with an O not a 0 (zero)
 * 
 * *****************  Version 2  *****************
 * User: Dstarr       Date: 4/24/96    Time: 9:17a
 * Updated in $/601test
 * Added symbols to support verbose mode
 * 
 * *****************  Version 1  *****************
 * User: Stevel       Date: 3/06/96    Time: 7:55p
 * Created in $/601cman
 * Initial release
