		MEDIAMATICS MPEG ARCADE(tm) Player
		(C) 1993-1996 Mediamatics Inc.
//++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

This is the Release 1.20.19 of the
Mediamatics MPEG Arcade(TM) Player.
This is a OM-1 compatible MCI driver enabling
Software only Decode of MPEG-1 streams.

The playback of VideoCD, CD-I and CD_Karaoke
disks is availabe by using the
"Mediamatics VideoCD Arcade Player" Device
entry.

This player reads MPEG-1 System, Video
and Audio Streams of upto 1.5Mbits/sec
from Hard Disk or ISO/High Sierra CD Roms and 
plays back on a DCI enabled graphics subsystem.


Configuration:
--------------
Whenever you change any configuration - either the
Audio or Video quality from the Device/Configure
Dialog - please stop playing all clips and exit
all running instances of Media Player.  New settings
will take effect when Media Player is re-run.
Also, use the same settings for all instances of
Media Player - you cannot choose to have different
setting for different clips.

Hardware Requirements:
---------------------

(1)	DCI Enabled graphics Card with OffScreen Color 
	space support and DCI software (dciman.dll and
	the DCI service provider).

(2)  	Any 8/16 bit Wave Card with Windows Drivers.
	The factory default is 16bit PCM Wave data.
	For 8 bit Cards - please configure the
	driver using Control Panel/Drivers/Setup

(3)	Pentium 75/90Mhz Processor based System
	with 256K second level cache.

(4)	For playback of CD's - any CD-ROM drive with 
	< 10% CPU utilization while reading 170Kb/sec 
	(see NewMedia Magazine article 1/6/95 - pp 22).
	capable of CD-I or VideoCD playback.
	
Installation:
-------------
1.	Please Install the graphics device driver and DCI software 
	and Video For Windows 1.1d or 1.1e. 

2.	Please Install Mediamatics MPEG Arcade(tm) Player
	by running the program SETUP.EXE on the software disk.

Performance Tuning
------------------

Use a high performance CD-ROM subsystem for playback of
ISO MPEG CD's i.e. - any CD-ROM drive with less than
 10% CPU utilization while reading 150Kb/sec. 
(see NewMedia Magazine article 1/6/95 - pp 22).

The amount of CPU time consumed by your HardDisk driver
or the CD-ROM device driver is the main culprit in
systems with poor performance.  The best performance is
obtained by using Enhanced IDE HardDisks and Enhanced
IDE CD-ROM drives connect to PCI IDE controllers.
SCSI Disks and SCSI CD-ROMS connected to PCI SCSI controllers
also offer good performance.

A performance drop of 20-40% (as seen by 20-40% poorer
framerate) will be seen in systems with slow HardDisk or
CD-ROMs.  Examples are older HardDisk connect to ISA bus
based IDE controllers which take 10% of the CPU
(Pentium 90) to read 150kbytes/sec.  ISA bus based
CD-ROM controllers take typically 30-40% CPU to read
150kbytes/sec - rendering your Pentium 90 to the level
of a Pentium 60 at best.

In comparison, an Enhanced IDE hard disk connected to
a PCI IDE controller takes about 3% CPU, and an Enhanced
IDE CD-ROM device driver (again connected to PCI IDE
controller) takes as low as 6-8% CPU when properly 
configured.

MPEG has a very low data-rate unlike AVI files - therefore
the overall bandwidth available on the drive is not
as important as the amount of CPU time consumed while
reading data from the drive.

Make sure your Pentium system has a Second level cache (at least 256K)
and that it is enabled.


Enhanced IDE configuration tips:

Use Enhanced IDE HardDisk and Enhanced IDE CD-ROM.
Connect only Enhanced IDE components to the PCI IDE
controller on your motherboard.  Any non-enhanced
IDE components on the PCI-IDE controller force
the entire IDE system to operate at normal IDE speeds
(about 2Mbytes/sec).  Enhanced IDE offers upto 10Mbytes/sec
I/O speed.

Enhanced IDE controllers connected to the ISA bus will
not give you the same performance as a PCI motherboard
IDE controller.
