Improvements:
-------------
This software update is provided to enhance your existing Indeo(TM)
Video drivers to the latest video technology for compressing, editing
and playing back video on your Intel microprocessor-based desktop
computer, using Microsoft's Video for Windows* Version 1.1. 

Indeo Video technology gives you the capability to capture and
compress video in a single step using Intel's Smart Video Recorder,
as well as, the ability to encode and/or decode (i.e. playback) video
using only software on your PC.

Intel's Smart Video Recorder product works with camcorders, VCRs and
laser disks to capture Indeo Video.  It immediately compresses NTSC
or PAL format files at: 320x240 pixel resolution up to 15 frames per
second (fps), 240x180 up to 24fps, and 160x120 up to 30fps. 

In addition, the built-in scalability of Indeo technology
automatically adjusts the playback frame rate depending on your
computer's performance capabilities.  This allows you to play Indeo
video files on any Intel Pentium(TM) or Intel486(TM) processor-based
computer.

This version of the Indeo Video R3.2 driver is an update to Indeo
Video R3.1 and Video for Windows V1.1. It provides:
   
   * Improved visual quality.  There is significantly more foreground 
     and background detail for most sequences, particularly at 15 fps 
     with data rates of 135KB/sec or higher.
   * Improved video playback performance at low data rates.
   * Improved 16-bit image quality and playback performance.
   * Improved audio playback at low data rates.
   * Compression and decompression of images up to 640x480 size in
     4-pixel increments.  Note: 640x480x10 video with a 240KB/sec transfer 
     rate, has been measured to play back at close to 10 frames per second.
   * Improved software encoder performance (2 to 5 sec/frame on a Pentium 
     processor system).
   * Faster initialization.
    
Indeo Video Drivers:
--------------------  
Indeo(TM) Video R3.2  -- V3.22.01.30 incorporates the new Indeo 
			 Video R3.2 software codec that produces
			 the highest quality video for software
			 playback on Intel microprocessor based
			 desktop computers.
			 [filename: ir32.dll]

Indeo(TM) Video Raw   -- V1.10.1.4 incorporates the raw/YVU9
			 codec.
			 [filename: iyvu9.dll]

Indeo(TM) Video R2.1  -- V2.17.003 incorporates a decompressor only.
			 It plays back files created with the older
			 R2.1 codec.
			 [filename: ir21.dll]

System.ini Entries:
-------------------
The Setup program installs the Indeo video drivers along with the
latest Video for Windows runtime.  It places the following entries in
the system.ini file for the Indeo video drivers:

[drivers]
VIDC.RT21=ir21.dll
VIDC.YVU9=iyvu9.dll
VIDC.IV31=ir32.dll
VIDC.IV32=ir32.dll

Previously, the recommended system.ini entries looked as follows:

[drivers]
VIDC.RT21=indeov.drv
VIDC.YVU9=indeov.drv
VIDC.IV31=indeov.drv

Indeov.drv was an "umbrella" driver that used a text file called
indeo.ini to point to the various Indeo video drivers.  The indeo.ini
file had the following entries:

[GLOBAL]
DRIVERS=IV31,RT21,YVU9
[IV31]
DEC=ir30.dll
[RT21]
DEC=ir21_r.dll
[YVU9]
DEC=ir21_r.dll

Indeov.drv and indeo.ini are no longer used and may be deleted if desired.
However, older applications, which install the Indeo video drivers, may still
use indeov.drv and indeo.ini.  Since the name of the latest Indeo video driver
has changed from ir30.dll to ir32.dll, this would prevent IV31 files from
accessing the latest driver.  To avoid this problem, an exact copy of the
latest ir32.dll file, named ir30.dll, is also installed by this setup program.
It is hoped the ir30.dll file will not be used.  But if another setup program
should change the system.ini entries to point to indeov.drv, then the correct
driver will still be accessed through ir30.dll.  In the future, this precaution
should not need to be taken.

Microsoft Setup Utility:
------------------------
The Setup.exe used to install this update is a modified version of the Setup
utility Microsoft provides to install the Video for Windows runtime.  It is
possible to make further changes to this program.  The Microsoft Setup program
used to come with V3.1 of the Windows SDK.  It is now available to registered
users of Visual C++ by calling Microsoft Product Support.

Software Prerequisites:
-----------------------
  * Video for Windows V1.1
  * Windows 3.1

Optimum System Requirements:                     
----------------------------
For the highest image quality and playback, the following system 
requirements are recommended:

   * Intel Pentium processor
   * System RAM: 12+ MB
   * PCI local bus graphics controller
   * SCSI hard drive

For best frame rate performance, put the graphics card in 8-bit
color mode.  For best image quality, put the graphics card in
24-bit color mode.     
   
Based on the application and the size of the video file, some
performance tuning of your computer's resources may be required. 

Updates:
--------
As new Indeo video drivers are released, they will be available on  
CompuServe INTELARCH and Intel's Application Support BBS at

This software update to Indeo Video R3.2 is a software codec change
only.  There have been no changes to the Intel Smart Video Recorder Driver.

Driver, V2.00.009 it is available on CompuServe* INTELFORUM and on
Intel BBS, (503) 645-6275. If you would like more information on
Intel's Smart Video Recorder, call:

Developers of AVI Editors:
-------------------------------
The following recommendation is for developers of AVI file editors.

To avoid unnecessary recompression, it is recommended the IV31 and
IV32 video formats be treated as the same video format. This speeds
up editing operations and improves video quality.  When a video editor
saves an edited AVI file, the video formats of the source video frames
are compared to the video format chosen for the target file.
Typically, any frames not in the target format are recompressed.  If
a clip contains a mixture of IV31 and IV32 frames, and the output
format is IV32, it is not necessary to recompress the IV31 frames.
The Indeo video R3.2 codec will play back both video formats.  

Known Operating Characteristics:
--------------------------------
 1) This version of Indeo video supports an active or dynamic
    palette.  However, a future update to the VfW runtimes from
    Microsoft is needed to use this feature. See item number 10
    below for details on using Indeo video's fixed palette.

 2) The new Indeo Video R3.2 driver can play back AVI files
    compressed using the older R3.0 and R3.1 drivers.  However, AVI
    files created by the R3.2 software encoder cannot be played back
    using the Indeo video R3.0 or R3.1 drivers.  Microsoft's Media
    Player will report the error "Video not available, cannot find
    'vids.iv32' decompressor."   
 
 3) The latest R2.1 driver does not display a setup dialog box from
    the Control Panel.

 4) ActionMedia(R) II boards and RT Video boards can not be used
    to provide hardware capture or accelerated playback of Indeo
    Video R3.x files.  Intel is considering options to provide
    these hardware drivers; however, there is no specific timeframe
    to announce at this time.

 5) Frames are dropped when capturing 320x240 or 240x180 images
    at frame rates greater than 15 or 24, respectively.  With
    the current hardware and software technology, this is the
    maximum frame rate that can be captured with 0 frames dropped.
   
 6) Using a Smart Video Recorder in systems with disk drives
    that have a transfer rate < 1.4 Mbytes/sec, random dropping
    of frames may occur.
 
 7) In VidCap, the overlay option is not supported.

 8) If you experience audio playback being out of synch with the
    video, try:
    a. Playing video from Media Player and configure playback
       (select Device/Configure...) to set "skip video frames if
       behind."
    b. Removing any TSRs.

 9) If you have an ATI Mach 32 graphics board you may need to set
    the "Device Bitmaps" to OFF to utilize the correct palette.

10) On systems using 8-bit graphic displays, a paletted shift may be
    observed in some applications.  To improve video performance,
    the Indeo video codec uses a fixed 8-bit palette.  One way to
    minimize this color shift, is to capture the palette  used by
    the Indeo video codec and apply it to the application that is
    incorporating video by:
	a) Loading an AVI file into media player. 
	b) Selecting copy object
	c) Opening PalEdit program and pasting the copied object
	d) Saving the palette
	e) using this .pal file as the color palette in the
	   presentation bitmap image.
