1.0 What is CAP


CAP is an acronym for "CATV/CCTV Advertisement Program", which
is a program and utilities developed by David R. Green as a
means to display scrolling multicolor text-based ads with a full
color graphics Banner.

CAP is designed for use by:

Cable companies - as a means to display community events and
bulletins, on a CATV Community Channel.

Businesses - video advertising or video shopping in a
store front window.

Museum/Art Gallery - display daily tour schedules, upcoming
events, or even digitized graphics of
artifacts with technical information.

CAP provides direct support for 36 Ad files of 128 Blocks
(although any number of data files may be present and used).
Each Block consists of 6 lines of 32 characters. That's a total
of 884,736 characters! or just under 40 minutes at the fastest
scroll Speed (0) with no Pauses (0); 19 hours at a comfortable
Speed (2) and Pause (4); and almost 5 days at the slowest Speed
(9) with full Pause (9).

The video display is partitioned into a Banner section and a Text
section. The Banner can be any graphics image either hand-drawn
or video-digitized, composed of 256 colors from a palette of
262,144 colors. The Text section shows the scrolling Ads in 16
text and background colors. The Text background can be any 1 of
16, and each individual line of text can be any 1 of 16 colors.
CAP supports the PCX Graphics file format for all Banners.

The CAP Editor is a full-featured word-processor, with line-wrap,
stream delete, insert/typeover modes, block insert/delete, and
more.


IF YOU FIND THIS PROGRAM USEFUL, PLEASE REGISTER. SEE README.EXE
















1.0 What is CAP 1



2.0 CAP Hardware Requirements


IBM AT or 80286/80386/80486 or PS/2 series computer with
286/386/486 CPU
VGA Video Adapter (100% IBM VGA Register and BIOS compatible)
minimum 256k RAM (160k FREE RAM)
a 1.2MB or 1.44MB Floppy Drive
minimum 20MB Hard Drive is recommended
OPTIONAL - a VGA to NTSC conversion unit

This program makes use of the iAPX 286 instruction set, and
therefore will not run on an XT or systems with 8088 and 8086
processors (80386 and 80486 operate fine). No 80286 Protected
or Privileged instructions are used.

This program requires a VGA card that is 100% IBM Register and
BIOS compatible, and uses modes 13h (320x200x256) and 03h (16
color text). A 16-bit bus VGA card is recommended.

A NTSC conversion unit is required if a standard VGA-output video
card is used, as opposed to a NTSC output VGA card. This is
required only if you need to display CAP over a CATV/CCTV system.
Single CPU/Monitor systems may use only a computer and a VGA card
with VGA monitor.

Use of the DOS Shell [F9] function requires a minimum 320k of RAM.

An 8MHz or faster AT/286 computer is recommended.

A computer with Video BIOS Shadowing capability is recommended,
as the BIOS Screen write facilities are utilized in CAP text
displays. Shadowing will allow for smoother text scrolling.

























2 2.0 CAP Hardware Requirements



3.0 Installing and Starting CAP


While CAP will run OK from a Floppy system, a hard drive is
recommended. A noticeable pause will occur on Floppy systems
during Banner and Data file loads.

Create a directory named CAP on your hard drive. Copy all files
from the CAP diskette to this directory. All Ad data and Banner
files MUST be located in the same directory as the CAP program.


In step form:

C:\> md c:\cap [ENTER]

C:\> cd c:\cap [ENTER]

C:\CAP> copy a:\*.* [ENTER]


The setup should look something like this:


C:\

CAP CAP .EXE Main executable program
CAP .DOC Cap Owner's Manual
~ README .EXE Program and Registration information
* .CAP CAP Advertisement text data files
BANNER .PCX default Banner graphics file
* .PCX Banner graphics files
PALETTE .GIF recommended Banner Palette
(GIF format)
PALETTE .PCX recommended Banner Palette
(PCX format)
PALETTE .LBM recommended Banner Palette
(Deluxe Paint format)


If you are missing any of the above listed files, please contact
the party from whom you obtained the package.
















3.0 Installing and Starting CAP 3



Batch File Commands


Sections of the following text are excerpted from the DOS 3.30A
manual, consult your DOS manual for additional information
regarding Batch files, in the section titled "Batch Processing".

You must name each batch file with an extension of .BAT.
If you press CTRL-C while the batch file is running, MS-DOS
asks you to confirm that you want to terminate the batch
process. (Note that CAP traps out Ctrl-C processing while CAP
is running).


ECHO

Purpose : Turns the batch echo feature on and off.

Syntax : echo [on] or echo [off] or echo [message]

Comments: turns the displaying of batch commands on or off.


GOTO

Purpose : Processes commands starting with the line after the
specified label.

Syntax : goto [:]label

Comments: allows you to goto different places within a batch
file.


IF

Purpose : Performs a command based on the result of a condition.

Syntax : if [not] errerlevel number command

Comments: allows conditional execution of commands.

















4 3.0 Installing and Starting CAP - Batch File Commands



Starting CAP


To run CAP, simply type (excluding the quotation marks):

"CAP"


To have CAP automatically run a specific data file, enter

"CAP filename"

the filename must be a valid .CAP Text Ad data file. It is not
necessary to add the .CAP extension to the filename.


Unless specified in the OPTIONS menu, CAP will use the default
Banner file named BANNER.PCX.

CAP automatically drops to black and exits to DOS upon
scrolling the last Block with text off the screen. To return
to the Editor, you must press ESC before the last line scrolls
off the screen.

If you miss the last Block, and the program blacks and exits,
you will be at the DOS prompt in 40-column mode. To return to
80-column mode, simply type MODE CO80 (the DOS external command
MODE must be in the path) otherwise C:\DOS\MODE CO80.



Running CAP from Batch Files


To loop one Ad text file indefinitely, create a batch file with
the following:

echo off
cd\cap
:repeat
cap file1
if not errorlevel 2 goto end
goto repeat
:end














3.0 Starting CAP - Running CAP from Batch Files 5



By building the AUTOEXEC.BAT file similar to this example,
multiple Ad files will be played, one after the other, and also
un-monitored systems will automatically restart the program after
power failures:

echo off
cd\cap
:repeat
cap file1
if not errorlevel 2 goto end
cap file2
if not errorlevel 2 goto end
cap file3
if not errorlevel 2 goto end
goto repeat
:end


A batch file may also be written that runs one file through 4
times, then runs a second file once, then loops back to the
beginning. Many different Ad formats can be produced using the
batch file formats.


CAP achieves this due to the fact that 3 different error levels
are returned to DOS at program termination:

0 - standard CAP Editor Quit
1 - CAP quit with an internal error
2 - CAP scroll section exit after completion of text file
scroll


To return to the CAP Editor screen from an Ad Scroll, press ESC.
As soon as the current Block has scrolled off the screen, you
will be put into the Editor section. Please note that the
current file you were working on, or Scrolling, including the
Block number you were at, are still valid in the Editor section.




















6 3.0 Running CAP from Batch Files



3.1 Installation problems



Are you using a 286/386/486 computer system?

Is CAP installed on a hard drive?

Are you using DOS 3.0 or above?

Do you have 256k or more RAM? 160k available for program use?

Do you have a VGA graphics card installed?

Is there an Ad data file present in the CAP directory?

Are you starting the program with the proper syntax?

Remove ALL TSRs (device drivers, disk-caches, pop-ups or other
hot-key programs) from your Config.Sys and Autoexec.Bat files
and try running CAP again. Be sure to make backup copies of
your Config.Sys and Autoexec.Bat files before you change them.

If CAP then runs, re-install each TSR one at a time until you
find the conflicting one. Sometimes the ORDER in which the
TSRs are installed affects the operation of the computer.
Contact the author at the address stated on the Support card
if have found some program that will not work with CAP.

Try running the program on a different IBM compatible computer,
possibly at a computer store.

If you are using some non-standard hardware (ie a particular
brand of VGA Video card), and you determine that there is a
conflict with CAP or any of the Utilities, please contact the
author.

Contact the author via mail, with a FULL description of the
problem, your equipment and setup, in addition to what TSRs you
are using. You will be notified as soon as possible about any
corrections. This Support feature is for Registered users only.

10 5.0 How Do I Use CAP?



OPTIONS BOX


Scroll Speed - determines the speed the lines scroll up
the screen. It is based on the
computer's Tick clock which is equivalent
to about 1/18th of a second.

Scroll Pause Time - the amount of time the Block text remains
on screen before it scrolls up and off.
In seconds.

Scroll Cycle Times - the number of times the Ad file will
repeat. 0 is NO repeats, 1 is 1 repeat
or 2 total scroll times.

Foreground Color * - the global color for all text Blocks.

Background Color * - the global color for the backdrop or
background behind the text.

Banner File - the name of the Banner file associated
with the Ad file. The default file
BANNER.PCX will be used if this is left
blank.



* These values will override and reset any settings done on
individual lines with the [F7] Color function.

If you accidently press [F8] Options Box, you may press [ESC] to
exit the Options section without disturbing your current settings.

You will be prompted with "Update the Color Set? [Y/N]" when you
press [ENTER] from the Options Box. If you wish to update all
other values EXCEPT the colors, press [N]. Pressing [Y] resets
any text colors to the new ForeGround value.

It is recommended that you select the Options Menu and set the
desired values BEFORE you assign color to individual lines.

You CANNOT Insert or Delete Block 1, as it contains all of the
Option parameter values. The Insert function will lose any text
in Block 128 as it moves all Blocks from the current Block up one.
The Delete function deletes the current Block, moves the next
Block down to its place, and clears Block 128 as all other Blocks
move downward.










5.0 How Do I Use CAP? 11



5.1 Creating Ad Files in CAP


The basic flowchart for creating Ads follows this sequence:

1. Use the Option menu to select the global color set for the
text. Any 1 of 16 colors may be selected for the Foreground
(text) and any 1 of 16 colors may be selected for the
Background. You may also select the Scroll Speed, message
Pause time, number of times you want the Ad file to loop in
it's scroll, and the name of the Graphics Banner you would
like to use for this Ad file.

2. Type the Ad text into each Block, using the Editor Window and
text editing Control keys.

3. Hi-light any lines of text, by changing their color using the
Color Function key [F7]. NOTE that these settings can be
reset if you go through the Options menu. See the section
above titled Scroll Options.

4. Save the Ad file.

5. You may run the Ad file directly, by pressing [F10], or quit
the program and enter "CAP filename" with filename being the
name of the file you just created.

6. To return to the Editor section, from a Scroll, press [ESC].
As soon as the current Block is finished, you will be returned
to the Editor section, with all Editor settings exactly where
you left off prior to running the Scroll [F10].

7. If you do not press [ESC] during the Scroll, when all Blocks
with any text have scrolled by (they will scroll by the number
of times specified in the Cycle Times OPTION menu) the picture
will drop to black, then exit to DOS.

* To make one file Scroll continually, create a batch file using
the name of the Ad file. See the section on Starting CAP.

* If your Banner picture is not being displayed, but the
Copyright Banner is, make sure you have not misspelled the
Banner name in the Options Box.















12 5.1 Creating Ad Files in CAP



5.2 Creating Color Banner Files


CAP uses the Industry Standard PCX Graphics format for its Banner
files.

Using most any Paint program such as Deluxe Paint II Enhanced or
PC PaintBrush IV+, draw your Graphic picture (remember to use
320x200 256 color mode only). You may use the PALETTE.* file, as
it displays the border area you may paint within, and has the
first 16 colors set correctly.

If your paint program saves in a different format, for example
Deluxe Paint II saves in LBM only, AutoDesk Animator saves in GIF
only, obtain a graphics file conversion program. Many good
shareware converters such as VPIC are available on many BBSs.
You may even have a converter program included with your paint
program, such as Deluxe Paint's Convert program.


! Be Sure your Banner uses only the upper half of the screen (320
pixels by 100 pixels). The bottom half of the screen MUST be
Black (using Palette Color 0, the first color). If you place
any graphics in the lower of the screen, it will be written
over by the scrolling text.

0 319
0


BANNER


99
100

text scrolls here


199

! The first 16 colors in the picture palette MUST be the standard
VGA 16 colors (they are used by the Scrolling Text). If you
are unsure, use the supplied default palettes.

Color 0 - Black Color 8 - Gray
Color 1 - Blue Color 9 - Light Blue
Color 2 - Green Color 10 - Light Green
Color 3 - Cyan Color 11 - Light Cyan
Color 4 - Red Color 12 - Light Red
Color 5 - Magenta Color 13 - Light Magenta
Color 6 - Brown Color 14 - Yellow
Color 7 - White Color 15 - Light White


! You may use all 256 supplied VGA colors within your Banners.


5.2 Creating Color Banner Files 13



5.3 Video Hardware & NTSC Color Information


Graphics Banners may also be input into CAP, by utilizing Video-
Digitization hardware. This allows any image to be captured from
a Video Camera or VCR into the computer. Many systems are
available, contact your computer retailer. Compuserve, Event
Horizons, in addition to many other BBS systems, have many
professionally digitized pictures available for consumer use.
These may be cropped or reduced to proper 320x100 size, then used
as a banner.


The current IBM standard VGA video cards are not directly NTSC
signal compatible. In order to get your CAP presentations
converted to this format, the use of specialized hardware is
required. The following devices are some of the hardware that is
available for this task.

VGA-TV Card
Willow Peripherals
190 Willow Ave
Bronx, NY 10454
(212) 402-0010

VGA Producer
Magni System Inc
9500 SW Gemini Drive
Beaverton, OR 97005
(503) 626-8400 or (800) 237-5964


When creating Graphic Banners, some limitation is placed on the
image due to the inherent limitations of the NTSC signal.

The use of certain colors and color blends should be avoided.
Reds tend to bleed and fuzz more than other "stable" colors.

Most Stable - Black, White, Grays
Stable - Green
Almost Stable - Blues, Browns, Yellows
Unstable - Red, Magenta

For best results, use stable colors for large solid-color areas
or backgrounds. If you must use reds, add a little green to help
stability.

The following combinations of colors bleed into each other and
cause a cancellation of both.

Red with Cyan
Blue with Yellow
Green with Magenta





14 5.3 Video Hardware & NTSC Color



5.4 CAP Limitations


Maximum 36 Ad files displayable in the Load/Save Directory
Window. CAP can use any *.CAP data file, but only the first 36
in the CAP directory will appear in the directory box. To use
any other data files, simply enter their appropriate name.

Maximum Advertisement File of 128 Ad Blocks.

Maximum 6 lines of 32 characters per Block.

Maximum 16 colors of text. (1 of 16 foreground, 1 of 16 background)

Maximum 256 colors for each Banner picture.

Maximum 320x100 pixels for each Banner picture.

Appendix A CAP File Format Information



CAP File Formats. May 1991


1. CAP Ad File Format.

Ad files are created within the CAP program, using the Editor
section of CAP.

CAP provides for 128 "Blocks" each consisting of 6 lines of 32
characters.


Each Block is 256 bytes in size, and only used blocks are saved
to disk, therefore, the number of blocks in a file can be
calculated by dividing the file size by 256.



line 1 32 bytes
line 2 32 bytes
