		  Indeo(tm) Video R3.1 Update -- V3.11.041
			    November 24, 1993

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 1.0. 

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 15fps, 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 486SX 
or DX processor-based PC.

This version of the Indeo Video R3.1 driver is an update to Indeo Video R3.0 
for Video for Windows V1.0, and provides:
   
   * Video off-line compression to achieve CD-ROM data transfer rates
     (150 Kbytes per second). Using the Data Rate box in the 
     Video/Compression Options dialog box of Video for Windows 1.0, you have 
     the ability to generate a video with a low data transfer rate.

   * A single software encoder with multiple levels of functionality. In 
     Indeo Video R3.0, 2 software encoders were referenced, i.e. the quick
     compressor and the super compressor.  The functionality of these 
     compressors have been combined from the user's perspective into the
     quality slider and data rate box.  

  * Compression using delta frames.  This s/w encoder recognizes the 
     specified key frame interval setting.
    
   
For users who have not updated to Indeo Video R3.0 this update also
provides:

  * Video playback that is two times faster than with earlier versions of 
    the technology.  PCs equipped with an Intel486(TM) or Pentium(TM)
    processor are able to playback a 320x240 file in full screen mode 
    at 15 fps using software only,

  * Dramatically improved picture quality and color reproduction, 
  
  * Playback support of files created by earlier Indeo Video versions. 
   

This software update to Indeo Video R3.1 is a software codec change only. 
There have been no changes to the Intel Smart Video Driver.  So, if you 
do not have the latest version of the Intel Smart Video Driver, V1.3.020, 
it is available on CompuServe* INTELFORUM and on Intel BBS, (503) 645-6275.

Updates are available
---------------------
As new Indeo video drivers are released, they will be available on  
CompuServe INTELACCESS and Intel's Application Support BBS, (916) 356-3600.

For Smart Video Recorder, s/w updates will be available on CompuServe 
INTELFORUM and Intel's PC and LAN Enhancement Support BBS, (503) 645-6275. 


Indeo Video Drivers:
--------------------  
There are 2 Indeo Video drivers contained in the self-extracting file,
INDOVW.EXE which is available now on Compuserve INTELACCESS and Intel's
BBS:

  * Indeo(TM) Video R3.1  -- V3.11.041 
      The new Indeo Video R3.1 software codec that produces the 
      highest quality video for software playback on Intel microprocessor-
      based desktop computers.
  
  * Indeo(TM) Video R2.1/Raw -- V2.16.009 
      The Indeo Video R2.1 codec plays video that was captured with the
      earlier R2.1 codec. This version includes an 8-bit dithering algorithm 
      that improves image quality on low end graphic subsystems, so 
      that existing Indeo video content looks better.
      
      Also, includes the code that performs the s/w playback of the raw 
      (uncompressed) YVU9 video data. Intel's Smart Video Recorder allows 
      the "raw" capture of video data and stores it as uncompressed 
      YVU9 data. This driver was previously named "Intel YVU9 Driver". 
			 
      NOTE: (1) This driver is the same one that was included in the 
		Indeo Video R3.0 Update.  
	    (2) DO NOT INSTALL this driver if your system is configured for 
		hardware accelerated playback.

Software Prerequisites:
-----------------------
  * Video for Windows V1.0
  * Windows 3.1

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

   * Intel486 DX2/66 processor
   * System RAM: 12+ MB
   * Local bus SCSI hard drive.

For best frame rate performance, use a local bus 8-bit graphics card.
For best image quality, use a local bus 16-bit graphics card.     
   
Based on the application and the size of the video file, some performance
tuning of your computer's resources may be required. 

Known Operating Characteristics:
--------------------------------
 1) The AVI files produced by this s/w encoder cannot be played back 
    using the older Indeo Video R3.0 driver. However, the new Indeo 
    Video R3.1 driver will play back AVI files compressed using the R3.0 
    driver.   

 2) ActionMedia(R) II boards and RT Video boards cannot 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.

 3) Frames are dropped when capturing 320x240 or 240x180 images at frame 
    rates greater than 15.  With the current hardware and software technology,
    this is the maximum frame rate that can be captured with 0 frames dropped.
