1.   What's new in v3.0
-----------------------

Over v2.0:
- Works with Windows 95
- Better allocation of VMC bandwidth for multiple video devices.
- Improved TV tuning for cable stations and weak signals.
- New 'All frequencies' TV mode if no stations are found.

Over v1.0:
-  VESA Media Channel compliant software interface
-  Works with 64-bit GrafixStar range
-  Improved TV tuning and saving TV settings
-  Tuner audio muting when TV video is not displayed


2. Hints and tips for using Captivator Pro/TV
---------------------------------------------

If you are using a GrafixStar card, then always use the VFW runtime DCI 
version that is supplied with GrafixStar.  If the Microsoft VFW Full-
version (includes VIDCAP and VIDEDIT) is installed, you can re-install
VFW DCI using the icon in the GrafixStar group.

To show or hide the title bar of the Captivator Pro/TV Video Window, 
double click in the video area. When the title bar is hidden, you move the
window by clicking in the video area and dragging the window.

When running the Captivator Pro/TV Video Window application, you can 
change channels without using the tuner dialog by pressing number keys: 1
for channel 1, 2 for channel 2, etc. 

When capturing VFW movies, use the Video Format that matches the current
display mode.  For example, use 16-bit 565 DIB when in 65k color display 
mode and 24-bit DIB when in 16.7M color display mode.  If you set a 
different Video Format (such as 15-bit 555 DIB when in a 256 color display 
mode) then you will NOT get better image quality.  The CPU will also have 
to translate the format and so the capture frame rate will be lower.


3. Installing multiple Captivator Pro/TV cards
----------------------------------------------

You can install up to four Captivator Pro/TV cards in your system if you 
have enough I/O and IRQ space available. 

****************************************************************************
*  To install another VMC card, you will need a VMC cable with three or    *
*  more connectors. These cables are available from VideoLogic. To order   *
*  your cable, please contact one of our customer support groups at 415    *
*  875 0606 from the USA, Canada or South America, or at +44 1923 271 300  *
*  from elsewhere.                                                         *
****************************************************************************

Assuming you have already installed one or more VMC option card(s), to 
install an additional Captivator Pro/TV follow the steps below:

(1) Leave the existing card(s) in your system. This prevents the new card 
    taking the I/O addresses of these cards when I/O scanning is performed. 

(2) Re-run the Captivator Pro/TV setup program and select Custom option.

    Setup detects that you already have cards installed and asks if you 
    want to add a new one. 

(3) Select the New option and follow the instructions given.

    Setup recommends a suitable jumper setting for the base address jumper 
    on the card; copies the necessary software; creates new program icons;
    and then prompts you to exit Windows.

(4) Exit Windows and switch off your computer.

(5) Install the new Captivator Pro/TV card in a slot next to one of your 
    VMC enabled cards.

(6) Use your new VMC cable to connect the cards.

    If your VMC cable has more connectors than you have VMC cards, you must
    connect the cards using sequential connectors. That is, if you have 
    three cards and a cable with four connectors, you can use connectors 
    1,2,3 or 2,3,4; you must NOT use a combination like 1,3,4 or 1,2,4.

    If you are using 928/MPEG Player (928Movie with a daughter card MPEG 
    Player), you must connect this card at one end of the VMC chain 
    (although not necessarily to the last connector on the cable - you can
    ignore this connector if it is not used). All VMC cables with more than
    two connectors have a nick in the cable between each connector; this 
    nick is on alternate sides of the cable and is used during the hardware
    sensing that enables your graphics card to identify the other VMC 
    option cards.  Make sure that the section of cable between the 928/MPEG
    Player and the next VMC option card has the nick on the edge of the 
    cable that points towards the front of your computer.


4. Using multiple Captivator Pro/TV cards
-----------------------------------------

Video control and Video Window

The Captivator Pro/TV setup program creates a new Video control panel and 
new Video Window icons for the additional cards. For example, if you install
a second card, its Video control panel icon will be called: "Captivator Pro
/TV-2 Video" and its Video Window icon will be "Captivator Pro/TV-2 Video
Window".

The command lines for the Video control and the Video Window icons are:
VLPOWER\CPLAPP.EXE "CaptivatorPro/TV" <n>
VLPOWER\VWINAPP.EXE "CaptivatorPro/TV" <n>
Where the number <n> indicates the board number 1 (board 2) to 3 (board 4)
and VLPOWER is the directory where you installed the Captivator Pro/TV 
files.

TV Snap
To switch cards in TV Snap, select one of the multiple MSVIDEO entries in 
the OPTIONS menu. This will open the capture driver for the corresponding 
board.

The installer creates multiple MSVIDEO entries in the Windows SYSTEM.INI 
[Drivers] section for each of the cards. The entries created depend on 
whether MSVIDEO entries already exist for other capture drivers. Assuming
no other capture drivers, the following entries for up to four cards, will
be created:
MSVIDEO  = VLPOWER\tgcapdrv.drv CaptivatorPro/TV 0
MSVIDEO1 = VLPOWER\tgcapdrv.drv CaptivatorPro/TV 1
MSVIDEO2 = VLPOWER\tgcapdrv.drv CaptivatorPro/TV 2
MSVIDEO3 = VLPOWER\tgcapdrv.drv CaptivatorPro/TV 3

Using VidCap
To create a VidCap icon for boards that do not use the default MSVIDEO 
entry, create an icon with a command line as follows:
VFW\VIDCAP.EXE -d<n>
Where <n> is the number of the MSVIDEO entry (e.g. 1 for MSVIDEO1) for the
board as described above.

9. How to get the PC to start up automatically as a TV
------------------------------------------------------
It is possible to get the PC to start up as a TV from power-on.
The user must first be familiar with the Windows Program Manager,
and must first have tuned to the local TV stations by following
the CaptivatorPro/TV instruction manual.

i) Windows 3.1

	a) Start by selecting 640x480 65,000 colour mode.
	(larger sizes may be possible depending on the
	type of graphics card).
	 
	b) Copy the 'Captivator_Pro TV Video Window' Program Manager item
	to the start-up	group. (control drag & drop)
	
	c) Remove any start-up passwords from the system.
	
	d) Launch the Captivator_Pro TV application, maximise the window, and
	double click on the video to get rid of the window border.
	
	e) Press Alt-F4 to quit the app.
	
	f) Start Windows automatically by changing the autoexec.bat start-up file.

ii) Windows 95

	a) Start by selecting 640x480 65,000 colour mode.
	(larger sizes may be possible depending on the
	type of graphics card).
	 
	b) Copy the 'Captivator_Pro TV Video Window' shortcut to the
	Windows\Start Menu\Programs\StartUp area.
	
	c) Remove any start-up passwords from the system.
	
	d) Launch the Captivator_Pro TV application, maximise the window, and
	double click on the video to get rid of the window border.
	
	e) Press Alt-F4 to quit the app.
	

Note: to remove any grey borders around the video, enter this line in the
[vdi api] section of the VDI.INI file in the WINDOWS directory:
	BlackBorder=1

To change channel, press <Ctrl>1 for channel 1, <Ctrl>2 for channel 2 etc., but
this will only work if the tuner buttons have been assigned to channels using the
scan dialog.


10. Tuning : new features
-------------------------

Version 3.0 allows the tuner to find weaker signals during the scan procedure.
This is done automatically during a scan.

Also, if the regional frequencies are not found by the scan facility, a new
'all frequencies' mode is available which scans all VHF and UHF frequencies.

The 'all frequencies' scan takes approximately five minutes, and so it should
only be used if the regional scan has not found all the channels.

To select the 'all frequencies' mode, the region dialog needs to be run.
This is done at install time or alternatively by deleting TUNER.INI from the
WINDOWS directory and then launching the tuner dialog from the TV   app.
 
At the region dialog, select 'UK/Europe: All Frequencies' for PAL tuners,
or 'USA/Japan: All Frequencies' for NTSC tuners.

Scanning will then test all frequencies within the range of the tuner hardware.

Finally, some problems with the cable TV scanning facility have been fixed,
and the 'all frequencies' mode is also available for cable TV, if required.
