IDEA Active X Demo Using Visual Basic and IDEA API Example 
Program are the two example programs recommended for use to 
evaluate the full functionality of the frame grabbers and 
video streamers.  They are included in:
Start/Programs/IDEA Version 2.3/IDEA Example Programs.

Upgrading to revision 2.3 from a previous revision of IDEA:
=========
For Developers Releasing an Application:
Your exisiting IDEA based application must be recompiled and 
relinked using the new IDEA libraries, header files, & OCX 
wherever applicable. Only updating the DLL's and Drivers 
without rebuilding may result in unstable operation.


For an end-user based system using IDEA TWAIN, Video for 
Windows, Image-Pro Plus, CVB, or the IDEA demo programs:
*   In "Control Panel", "Add/Remove Software", uninstall 
    the current IDEA software.
*   Decompess and run the "InstallScan20.exe" program on 
    the IDEA v2.3 CD or the downloaded version located 
    in the "ADDONS", "INSTALLSCAN" directory.  Select "Clean
    Installation"
*   Then install the new IDEA software.

Updates from the IDEA 2.2 Release
(Details)
==================================
New Additions Detailed:
1)  Monochrome input on AccuStream 170 and I-RGB 165 & I-RGB 200
	This revision contains application support for Monochrome capture on
	AccuStream 170, I-RGB 165 & I-RGB 200 boards.
	Refer to the RGBMONCHROME.PDF  file in the FORESIGHT\IDEA\DOCUMENTS
	directory for detailed information.
	Note: This mode of operation is not supported by the AUTOSYNC 
	configuration utility. Thus, these CHP files must be edited manually.


2) Native Library Functions:
   a) The native library will now automatically put any streaming-capable board
   into continuous capture mode.  What this means is that the library has the
   board streaming to a small set of circular buffers.  A capture via the 
   eHP_SnapToBuffer() API will transfer the newest buffer to the application. 
   This results in much faster static grabs since the the grab operation no longer
   requires internal setup and waiting for the proper syncs.  Its possible that this
   may lead to an incompatibility with your application.  To disable this feature
   add the following code to your application after you have obtained a board handle
   through the claim API:

    UpdateVideoSettingLong uvsl;
    uvsl.lValue = 0;
    uvsl.pRSet  = 0;
    eHP_SetControlValue(bh, "ContinuousGrabEnable", sizeof( uvsl), (void *)&uvls);
  
   This will put the library back to its previous mode.  Note that continuous
   capture is not supported for I-Color.

   b) nHP_CLaimAll will no longer automatically usurp board handles.  This
   function used to give access and control of all boards to the last application
   to make the call.  This lead to instability in multi-board, multi-application
   environments.  So now nHP_ClaimAll will only give the applications access to
   all "previously unclaimed" boards.  It is possible that your application took
   advantage of this old behavior to indiscriminately claim boards at various 
   points in your application.  This will no longer work.  You must explicitly
   unclaim your boards before calling nHP_ClaimAll if you expect to retrieve 
   valid board handles.

   c) You must pass a valid rset structure when making a call to query the current
   IRGB/Accustream cable type.  This is done through a call to:

     eHP_GetControlValue( bh, "IRGBCable", sizeof( uvl ), &uvl );

   The prset member of uvl must now point to a valid, up-to-date rset structure.

3) ActiveX Control
    a) You can no longer invoke the configuration dialog when doing continuous
    capture and display - also known as GDI live display.

    b) Since the native library will now automatically put a streaming-capable
    board into "continuous capture mode", there is no reason to do this in
    the ActiveX control.  Applications that use this method can safely remove
    it while still getting the benefits of faster static capture.

4) TWAIN Driver:
    a) The dialog box is now fully resizable.  To change the size of the
    dialog box, grab one of the outer borders and drag to the appropriate
    size.  The driver retains the position and dimensions the next time
    it is invoked.

    b) Live video display no longer requires a direct draw compatible 
    display card.  This means that the update may be a little slower, but 
    will not have problems scaling or re-sizing the image with older 
    video display cards.

5) Video For Windows Driver:
    a) Pause command truly pauses streaming video instead of stopping and
    restarting.

    b) A new support application call VFWINIT is included in the release.
    This application should be used to set up the hardware profile and the
    display options before using the driver with a VFW compliant application.
    All of these parameters can be changed in the applicaton by invoking the 
    "Video Source" or the "Video Format" dialogs.

6)  Improved throughput performance of the AccuStream 170 to 250 MB/second 
    when using 64 bit/66 MHz PCI

7)  Added Auto-SYNC support for DVI signals with AccuStream 170

8)  Added YUY-RGB (SMPTE 170M/ITU-R BT.601 only) software conversion with 
    AccuStream 170, I-RGB 165, and I-RGB 200

9)  Added DVI configuration utility for setting default pass-through 
    resolution, behavior of hot plug detect, and enable/disable of DDC.  
    This utility can be found in FORESIGHT/IDEA/UTILITIES

4. Click on the "Video Capture Devices" entry.
5. Click the "Add" button.
6. Make sure that "Unlisted or Updated Driver" is highlighted 
   and press "OK".
7. Browse to the driver directory, "\Foresight\Idea\drivers\NT_2K"
   and press "OK".
8. The "Add Unlisted or Updated Driver" dialog should be showing 
   "Foresight Imaging Frame Grabber".  Press "OK".

   compliant application.


===========
Other Notes:
============
1) Auto-SYNC requires  SHLWAPI.DLL.  This is usually 
   installed with versions of the Internet Explorer 
   from version 4.0 onward.  If you are installing to 
   an older version of NT 4.0, you may not have this 
   DLL.

2) You must install the DirectX SDK (available from 
   Microsoft) in order to recompile and build the 
   VideoTest application.

3) You must install the LeadTools Imaging library to 
   build the DICOM DLL and use the DICOM functionality.

4) You must install the Pegasus Compression CODECS to 
   use compression in the demos.
