Overview
--------
The purpose of this updated version of INDEO.DRV (V2.11) is to 
improve software playback performance.  This Indeo Video driver supports
software only compression/decompression. While it does not support
playback on ActionMedia(R)II or RTVideo boards, it does provide support 
for software playback of video files captured by Intel's Smart Video
Recorder, including 320x240 video.
   

Installation
------------
Indeo(TM) driver is distributed in compressed format as a 
self-extracting ".EXE" file.  This file is named "INDEOZIP.EXE" and 
contains two files: INDEO.DRV and INDEO.TXT.

To install this updated version of INDEO.DRV:

To replace the older version of the Indeo driver:
   * move to the windows directory [e.g. c:\windows\system]
   * rename INDEO.DRV as a backup [e.g. indeo.old]
   * copy the new INDEO.DRV to the windows\system directory
 
To verify the installation, use the Windows Control Panel, select Drivers,
and double click on Indeo(TM) Video Driver from the list of Installed 
Drivers.  The driver setup information will be displayed and it must
report version 2.11.


Enhanced Features  
-----------------
Indeo(TM) V2.11 driver update contains the following enhancements:

   * Software Playback:
      Supports playback of AVI files captured using Intel's Smart 
      Video Recorder.
       
   * Performance Improvements: 
      Optimized algorithm for decode/color conversion to obtain the    
         maximum performance on current x86 microprocessors.

   * Backoff Strategy: 
      For a smoother picture during playback, improved the backoff
      strategy that determines when to drop frames based on a PC's 
      performance.  Autodetection of a PC's performance is
      determined and adjusted for in a matter of a few frames
      at the beginning of each file.

   * Zoom by 2: 
      By directly implementing the "Zoom by 2" option, improved the
      playback performance of larger video resolutions.

   * RGB24:
      - Implemented full interpolation in Y, V and U, which improves
        the color quality image in high color mode.  In addition, during
        video editing, VidEdit will receive a file in the high color mode, 
        which in turn, will produce a better color quality image after 
        editing than was seen with the previous Indeo Video driver.
      - Fixed bugs in the 24-bit code which improved both speed 
         and color quality.
        
   * Encode Improvements: 
      To be ensure that the compressor is configured for the same
      quality settings whether using software encode (via VidEdit) or
      hardware encode (via VidCap), a new dialog box was added. This
      dialog box allows the user under VidEdit to configure the compressor
      for 1 of 4 states, e.g. 0=Highest Compression, 3=Highest Quality. 
      The quality slider provided by Microsoft in the Compressor Option
      dialog box has been disabled.
      
   * Bug Fixes

Usage
-----
   * Video Capture Optimization & Quality
      - For the best tradeoff between video compression and video
         quality, set the key frame rate to 3.
      - For the highest quality video and for highest quality playback,
         set the key frame rate to 1.
   
Known Problems                            
--------------
   Hardware
   --------
   1. The playback of AVI files captured by Intel's Smart Video Recorder 
        are software only.
   2. This version of the Indeo driver is software playback only.
        Therefore, it does not recognize the video accelerator boards,
        such as ActionMedia II and RTVideo boards, and will disable
        the hardware playback option. 
   [Note: these problems will be fixed in the next release of hardware
          drivers]
