+      **  XFree86 driver for TV output on ATI Radeon cards **
+      *******************************************************
+
+Copyright (c) 2003-2004, by Federico Ulivi <[e-mail]>
+Released under the GNU General Public License, version 2.
+
+1. About this driver
+--------------------
+
+This driver was developped as a part of ati.2 project. Its purpose
+is to enable the TV output of ATI Radeon cards when running the
+XFree86 graphical environment.
+
+2. Status of the driver
+-----------------------
+
+The driver is in early development stage. It currently works with
+those cards having a Rage Theater chip for TV output or with cards
+having the tv module inside the Radeon chip (ERT, Embedded Rage
+Theater, is my name for the latter).
+The driver was successfully tested on these cards:
+- Radeon 7200 / European model (TV out hw: RT 100)
+- Radeon 9000 (TV out hw: ERT)
+- Radeon 9200SE (TV out hw: ERT)
+- Radeon 7000 (TV out hw: ERT)
+
+3. Making it work
+-----------------
+
+The driver is always loaded by the Radeon driver. If you need to
+disable this auto-loading mechanism, just set the "TVOutput" option
+(see below) to "NOLOAD".
+In principle the driver should coexist with video grabbing functions,
+especially on those AIW cards where TV output is done by ERT
+inside Radeon.
+
+Principle of operation of the driver is very simple. Driver enables 
+tv output whenever the current screen resolution and tv standard match
+one of a set of pre-computed combinations. In all other cases tv output
+is simply kept disabled.
+The driver currently works in the so-called "clone" mode only. This means
+that the image on the TV screen is exactly the same as the one on the
+monitor.
+
+The driver is enabled by adding a "TVOutput" line in the "device"
+section of XF86Config-4 file (this file is usually located in /etc/X11
+directory). Syntax of this option is very simple:
+
+Section "Device"
+ ..
+ ..
+ Option "TVOuput" "<name of tv standard>"
+EndSection
+
+Names of recognized TV standards are:
+"NTSC"
+"NTSC-J"
+"PAL"
+"PAL-CN"
+"PAL-M"
+"PAL-N"
+"PAL-60"
+
+If "TVOutput" is not present or its value is invalid, TV output is kept disabled.
+
+In the current version of the driver these are the recognized TV standard &
+resolution combinations:
+
+PAL	800x600
+NTSC	800x600
+
+More combinations will be added in future releases.
+
+4. XV Interface
+---------------
+
+The driver has an external interface through some Xv attributes. 
+You can change the value of these attributes by using the tvo_set utility
+(see below).
+
+XV_TVO_STANDARD		Settable/Gettable
+	This is the tv standard in use by the driver. Its value is encoded
+	according to this table:
+
+	0	NTSC
+	1	PAL
+	2	PAL-M
+	3	PAL-60
+	4	NTSC-J
+	5	PAL-CN
+	6	PAL-N
+	7	Keep TV off
+
+XV_TVO_MODE_COMPAT	Gettable
+	This attribute is set to 1 whenever TV output is enabled, i.e.
+	whenever the current resolution & tv standard combination is 
+	recognized by the driver. 
+
+XV_TVO_HPOS	Settable/Gettable
+	Horizontal position, valid range is [-5..+5]. 
+	This attribute defines the horizontal position of the TV image.
+	Higher values shift the image to the right, lower values to the left.
+
+XV_TVO_VPOS	Settable/Gettable
+	Vertical position, valid range is [-5..+5]. 
+	This attribute defines the vertical position of the TV image.
+	Higher values shift the image upward, lower values downward.
+
+XV_TVO_HSIZE	Settable/Gettable
+	Horizontal size, valid range is [-5..+5]. 
+	This attribute is used to set the horizontal size of TV image.
+	Higher values enlarge TV lines, lower values reduce them.
+
+Default value for XV_TVO_HPOS, XV_TVO_VPOS & XV_TVO_HSIZE just after
+X Window start is 0.
+
+You might ask where a vertical size attribute has gone. It was not included
+because it's quite hard to implement (it requires changing many timings in
+the CRTC). For the moment I'm not planning to work on it.
+
+5. tvo_set utility
+------------------
+
+tvo_set is a command line utility that is used to change TV output
+attributes while X Window is running. It offers a somewhat more
+friendly interface to XV_TVO_* attributes.
+
+This is how to compile tvo_set:
+- cd to tvo_set directory
+- xmkmf
+- make
+- make install
+Last step should place the executable (tvo_set) in /usr/X11R6/bin.
+
+This is the invocation syntax:
+tvo_set [-display host:dpy] [<cmd> <attribute> [<value>]]
+
+tvo_set is not case sensitive for <cmd>, <attribute> & <value>
+fields.
+When no <cmd> is given, tvo_set just dumps the current state of
+TV attributes.
+
+Recognized commands:
+set <attribute> <value>   Set <attribute> to <value>
+inc <attribute>           Increment <attribute> by 1
+dec <attribute>           Decrement <attribute> by 1
+zero <attribute>          Set <attribute> to 0
+
+Recognized values for <attribute> field:
+hpos	Horizontal position
+vpos	Vertical position
+hsize	Horizontal size
+std	TV Standard
+
+When setting "std" attribute, both the numeric value and the name of the 
+standard are valid, see following table.
+
+Table of TV standards:
+0	NTSC
+1	PAL
+2	PAL-M
+3	PAL-60
+4	NTSC-J
+5	PAL-CN
+6	PAL-N
+7	OFF
+
+Examples:
+"tvo_set set std ntsc"
+	Set standard to NTSC
+
+"tvo_set set std off"
+	Turn off TV output
+
+"tvo_set set hsize 5"
+	Set hsize to 5
+
+"tvo_set inc hpos"
+	Shift image a bit to the right (increment hpos by 1)
+
+"tvo_set zero vpos"
+	Restore default value for vpos
+
+
+6. WARNING
+----------
+
+It's important that you are aware of the fact that, when TV output is active,
+the monitor is driven at the same vertical refresh frequency as that of the
+TV output. This means 50 or 60 Hz according to the standard you're using.
+NO CHECK IS DONE IN THE DRIVER ABOUT THE CAPABILITY OF THE MONITOR TO
+SUSTAIN THESE FREQUENCIES. You should look up in the monitor manual
+and check that 50/60 Hz is within the limits. IT IS POTENTIALLY HARMFUL
+TO THE MONITOR TO BE DRIVEN AT A FREQUENCY OUTSIDE ITS OPERATING RANGE.
+
+Note, however, that most monitors should accept a 60 Hz vertical frequency,
+since this is used in standard VGA modes. You should really check for 50 Hz 
+compatibility if you are going to use any related standard (PAL mostly).
+ATI manuals recommend checking for 50 Hz compatibility (they take
+60 Hz for granted).
+
+One last thing: I did no testing on cards having DVI/LCD outputs
+so I'm not sure about the driver behaviour with this kind of displays. 
+Be warned.
