Chapter 1 - Overview
Product Introduction
The EN20 is a two-channel High and Standard definition MPEG-2 or H.264 encoder
supporting ATSC and DVB tables through ASI and IP transport streams. The EN20 can be
ordered with optional QAM modulation for distribution applications.
It inherits Adtec’s broadcast quality compression, advanced feature set, service
performance and reliability in the new dense two-channel platform targeted towards
broadcasters, cable and IP compression applications.
The device automatically detects video and audio from two sources (combination of
HD and SD acceptable), encodes, multiplexes and sends them back out as one combined TS
via IP, ASI or optional QAM. Closed captioning and support for Emergency Alert (EAS)
triggering are standard.
EN20-02: Dual Channel SDI HD and SD MPEG-2 Encoder with ASI and GigE outputs. Auto
detects two channels of any combination of high and standard definition sources with
embedded PCM or Dolby audio via SDI inputs. Alternate inputs are CVBS (BNC connector,
supports SD only) and analog audio supplied via DB-9 input. Encodes video to MPEG-2
Transport Stream and encodes PCM audio to Dolby AC3 (with feature key enabled) or MPEG1 Layer 2. Passthru for Linear PCM and Dolby audio (2.0, E, and 5.1) is also supported.
EN-20 then encapsulates MPTS and outputs ASI and GigE concurrently. Supports ATSC A69
PSIP and DVB-SI ETSI EN 300 468 service information, closed captioning support per
embedded SDI or per CEA 608 via composite video input with up-conversion to CEA 708
Digital captions internally and EAS triggering. Condition Access BISS 1 / E encryption
included.

Introduction
Adtec Digital has deployed a web-based configuration and control software application for
our products. The program is optimized to work with the following browser versions:
● Firefox: 3.5 (recommended)
● MS Internet Explorer: 8.0 and higher
● Safari: 3.0 and higher
● Google Chrome: 5.0 and higher
Note for Safari users:
● The program is designed to use the Bonjour Zero Configuration Protocol.
○ When using Safari, click on the " ^^ " symbol to open a networked devices
list.
○ Select the device to point the browser to that device's IPA.
Logging In
Access the application by pointing your web browser to the unit's IP address. The following
screen (image reduced for clarity) will appear:
Log in to the application by clicking the "Proceed to Login" button and typing in the user name
'adtec' and the password 'none' in the pop-up box that appears.
The application has two operating windows, the Status Window and the Main Window:
Status Window: The Status Window is fixed on the left-hand side of the screen- it will display
regardless of what function is being displayed in the Main Window. The current status
parameters of the unit's are always in view and are updated in real time.
Main Window: The Main Window is used to access the device's configurations and operating
settings.
Help Notes: Help blurbs are available for the configurations on each tab; click on the "Question
Mark" symbol next to the configuration name for a pop-up screen explaining the control.
Upgrading your device
To upload new firmware versions, click on the <Upload> button in the top navigation bar next to
Log Out. A pop-up screen will allow you to browse for the firmware file by clicking Upload within
the pop-up screen. After the new version is uploaded, its availability on the device will display
under "available versions".
After the new version is uploaded, Click <Install> to extract the firmware. It will then be
available under Installed Versions.
Once you have the version you wish to use in the Installed Versions list, you can select into it
by clicking the select button. The unit will reboot and come up running in the new version.
Chapter 4 - How-To Guides
How to Complete a Manual Upgrade
You can upgrade your Adtec device's firmware via built-in web-based application, described
in the Upgrade Tab section, or via a Telnet/FTP session, described in this article.
To update your Adtec device 's firmware via a Telnet session, perform the following:
Manual Upgrade Process
Step Action
1 Obtain the desired firmware version file from www.adtecftp.com
note*: Firmware releases are found in the Public Folders -> Firmware -> Release
-> section of the website, in a folder marked with the product name. username:
adtecftp password: adtecftp2231
note**: Windows Internet Explorer renames adtec firmware file extensions to .gz .
When saving please add a t within the extension to read .tgz if IE has renamed
your file.
2 Using your favorite FTP client to upload the firmware file to the device.
If you are unfamiliar with FTP you may use a 'My Computer' window and type in
the address bar, ftp://adtec:none@192.168.10.48 where 192.168.10.48 should be
replaced with the IP Address of YOUR device. You may then drag and drop the
firmware file into the hd0 folder.
3 Open a Telnet session and enter the IP address of the unit you are going to
update.
note*: If you are unfamiliar with telnet, open a command prompt window
(windows: start -> run.., mac: macintosh hd -> applications -> utilities ->
terminal) and type: telnet 192.168.10.48
4 Enter the username as ' adtec ' and the password as ' none '.
5 Enter the following in sequence: *.ecmd stop
6 *.sysd vrn search - from the results, look for the pathname of recently uploaded
firmware file
7 *.sysd vrn install [pathname of the .tgz file]
ex: *.sysd version install /media/hd0/EN-20-v1.00.12.nfcms.tgz
How to Connect via Telnet
* Using Telnet (standard 23 port)* To connect to your device using a terminal session, you
will need to set the IP address of the unit. See earlier instructions on setting the IP via the
front panel.
Using a terminal window, complete the following:
Step Action
1 Type 'telnet x.x.x.x' in a terminal window, without quotes, where x.x.x.x is the IP
address of the unit.
2 Press <Enter>.
3 When prompted for a username, enter adtec.
4 When prompted for a password, enter none.
Once you see "User 'adtec' connected", the session is open and you may issue API
commands to the unit.
For the EN-20 device, there are specific commands for the modulator, encoder, and the
unit's operating system. Each has a unique way of accepting commands. If using telnet is
your preferred method of communication to your device, familiarize yourself with the API
commands and their respective command handlers. For more information on this, point your
browser to the IPA of your unit and look through the API notes that are described for the
device.
How to Connect via FTP
FTP connections can be made to the adtec device using any ftp client.
Host: <ipa of the unit>
Default Username: adtec
Default Password: none
Port: 21
FTP is only useful for collecting logs from the device.
How to Use API Commands
The Adtec EN-20 device is unique in that it handles two physical encoders. To accomodate
commands for controlling both encoders, you will need to specify which encoder you are
working with for each command you issue.
Please make the following adjustments:
● Instead of using *.ecmd as noted the API descriptions, you will need to use.
○ *.ecmd0 to specify the first encoder.
○ *.ecmd1 to specify the second encoder.
Example: (*.ecmd0 TRA) will give you the transport status of the first encoder.
How TMR is Configured
The EN-20 is sold with an optional integrated QAM modulator. TMR is affected differently when
the modulator is installed. Below outlines the differences.
When the QAM modulator is present the TMR (Transport Stream Mux Rate) is controlled
by the modulator’s clock.
When in Annex B mode, the rates listed below will be configured and can not be changed.
Annex B QAM 256 the TMR is set to 38.810671 bps.
Annex B QAM 64 the TMR will be set to 26.970186 bps.
When in Annex A mode, the symbol rates are adjustable and that in turn affects the configured
TMR. The higher the symbol rate, the higher the data rate.
When the QAM modulator is not present, TMR can be configured via the webUI or from
the front panel Services Menu / TS Mux Rate (bit/s). The maximum TMR is 80 Mbps.
How Video Rates are Configured
Video rates can be configured manually or automatically. The factory default is to automatically
set the video rate based on TMR. This option is referred to as VAF (Video Autofill). VAF
determines what the TMR is. It reserves 3.5% for null packets. It detects the video input
resolution for each channel. It automatically calculates the required headroom for audio pids. It
sets the video bit rate for each channel accordingly to maximise available bandwidth.
SD encode bitrate = 1.00 to 15.00 Mbps
HD encode bit rate = 7.00 to 60.00 Mbps
Example:
TMR is set to 40 Mbps.
Channel 1 has a SD 720x480i source.
Channel 2 has a HD 1920x1080i source.
15.00 Mbps will be allocated to channel 1 because the source is standard definition. 19.10Mbps
will be allocated to channel 2 (this is the available band with after VAFs calculation)
If VAF is set to off the video rate can be manually adjusted for each channel. If you configure a
channel at a video rate that would cause a egress overflow the VAF logic will constrain the
misconfiguration and reconfigure the video rate for both channels.
Example:
TMR is set to 40 Mbps.
Both channels have a HD1920x1080i source.
Both channels audio = 256 kbps
Video fill is set to off.
If both encoders are set to 19.10 Mbps and you want to reconfigure them to say 15.00 Mbps for
channel 1 and 25.00 Mbps for channel 2. This would cause an egress overflow condition
because you have not factored in the 3.5% reserve and bandwidth occupied by audio pids.
Even though VAF is set to off it’s logic will override the configuration request and constrain the
video rates back down to 19.10 Mbps for both channels. To obtain the desired configuration.
You would need to recalculate your rates. Then configure channel 1 to 15.00 Mbps then
channel 2 to 23.00 Mbps.
How to enable EAS mode
EAS can be enabled from an automation system contact closure or from the webUI EAS tab.
To enable EAS in VIDEO+AUDIO via the 9 Pin GPIO, short pin 5 to pin 7.
EAS GPIO Connector Pinout
To enable EAS mode from the webUI. Click the EAS tab. Select the desired EAS mode, then
click the large GO button. To disable EAS mode press the large STOP button.
How to configure Network EAS Triggering
By default the YUV2QAM is configured to send a trigger over the network to all other dual
channel encoders (HDMI2QAM, YUV2QAM, or EN-20) to also enter EAS enabled state. This
feature can be disabled by unchecking the box next to “Network EAS Triggering” then
pressing the apply button on the EAS tab.
Audio passthru - Dolby E, Dolby D, LPCM
The Adtec EN-20 encoder supports one pair of audio encoding or one pair of audio passthru.
An audio passthru consists of a compressed bitstream ( Dolby E 20 Bit / Dolby E 16 Bit /
Dolby Digital / Linear Acoustic Stream Stacker 2 ) or an uncompressed stereo pair ( LPCM )
from embedded SDI passed into the egress transport stream ( IP, RF, ASI ).
To enable Audio passthru for Audio 1:
Step Action
1 On the Audio -> Encoder 1 subtab in the Web GUI Control Application, configure
the "Audio Mode" for <PASSTHRU>.
2 Configure the “Audio Input” for <SDI>.
3 Select the type of audio from the “Type” drop down. <Dolby Digital>, <Dolby
E>, or <Linear PCM / E2>.
note: If Dolby E or Dolby Digital is valid at the input, the bit depth and bit rate
are automatically determined after clicking Apply.
4 On the “PID” tab, type in the desired Audio PID for “Audio 1”.
Common Passthru Problems:
Dolby E Line Placement and/or Dolby E Continuity Count Errors:
Dolby E audio compression technology is designed so that 1 Dolby E audio frame
corresponds to 1 Video frame. This 1:1 ratio of video and audio timing was designed to
assist in Video editing and seamless cuts without losing audio data. Due to the crucial and
sensitive timing, Dolby E encoders must have a reference phase locked to the video. In
other words, the SDI video timing feeding the encoder must match the same composite
reference timing that is connected to the Dolby E encoder. A simple black burst generator
that does not share the same SDI video timing will not work to source a Dolby E encoder. A
composite video reference that shares the same timing as the video source should be used.
The encoder preserves audio and video timing as it is presented. If the audio timing does
not match video timing at the inputs of the encoder, there will be line placement errors
and/or CRC errors seen on a decoder.
No Detection of Dolby E / Dolby Digital, Front Panel shows “DE ---”, “DP ---”, “LP ---”:
The encoder will automatically detect the bit depth of Dolby E ( 16 / 20 bit ) and the bitrate
of Dolby E / Dolby Digital. If Dolby E is selected and Dolby Digital is presented, the encoder
will change automatically and vice versa. If Dolby Digital is selected and Dolby E is
presented, the encoder will change the configuration automatically. If the front panel shows
dashes for the detected bitrate ‘---’, Dolby is not being detected. This is most commonly
due to a mis-configured SDI Audio Matrix or Dolby not being present on the specified input
pair. Look at the SDI signal on an SDI analyzer to verify that Dolby is present on the pair
intended. If an SDI analyzer is not available, one troubleshooting tip is to set the mode to
ENCODE. If silence or regular audio is heard on the decoder, a compressed bitstream is
not being presented on the corresponding input. The SDI matrix can be changed to each
pair without restarting the encode session. Once hash is heard, then a compressed
bitstream should be present. Set the mode back to Passthru for the automatic detection
mechanism to configure the Dolby type and bitrate.
Vertical Interval Time Code
Vertical Interval Time Code (VITC) is typically used in transmissions that require time code
from the originating source to be preserved. It was originally developed for analog
television recording systems, but has new standards for transmitting in digital systems
(SMPTE-12M-1 / SMPTE-12M-2). Preserving time code is beneficial for future editing and
playback of captured material.
EN-XX-series devices with an SDI input can pass VITC ancillary data as part of the ANC PID.
The ANC PID is a separate PES located in the transport stream. Additionally, time code
within the GOP of the video will also be adjusted at encoder start up to match the incoming
ancillary VITC.
VITC data packets will contain a DID of 0x60 and an SDID of 0x60. The VBI tab contains an
SDI ancillary inspector that allows users to view ANC data present at the input. This tab
can be viewed for verification of present ancillary data at the SDI input.
To enable VITC passthrough:
Step Action
1 On the VBI Tab in the Web GUI Control Application, configure the "VBI Source"
for <SDI>.
2 On the PID Tab in the Web GUI Control Application, select the <On> setting for
"ANC PID Active".

Everyone is permitted to copy and distribute verbatim copies of this license document, but
changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change
it. By contrast, the GNU General Public License is intended to guarantee your freedom to
share and change free software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software Foundation's software and to
any other program whose authors commit to using it. (Some other Free Software
Foundation software is covered by the GNU Library General Public License instead.) You can
apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public
Licenses are designed to make sure that you have the freedom to distribute copies of free
software (and charge for this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it in new free programs;
and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these
rights or to ask you to surrender the rights. These restrictions translate to certain
responsibilities for you if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you
must give the recipients all the rights that you have. You must make sure that they, too,
receive or can get the source code. And you must show them these terms so they know
their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this
license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone
understands that there is no warranty for this free software. If the software is modified by
someone else and passed on, we want its recipients to know that what they have is not the
original, so that any problems introduced by others will not reflect on the original authors'
reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the
danger that redistributors of a free program will individually obtain patent licenses, in effect
making the program proprietary. To prevent this, we have made it clear that any patent
must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION
AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the
copyright holder saying it may be distributed under the terms of this General Public License.
The "Program", below, refers to any such program or work, and a "work based on the
Program" means either the Program or any derivative work under copyright law: that is to
say, a work containing the Program or a portion of it, either verbatim or with modifications
and/or translated into another language. (Hereinafter, translation is included without
limitation in the term "modification".) Each licensee is addressed as "you". Activities other
than copying, distribution and modification are not covered by this License; they are outside
its scope. The act of running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the Program (independent of
having been made by running the Program). Whether that is true depends on what the
Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive
it, in any medium, provided that you conspicuously and appropriately publish on each copy
an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that
refer to this License and to the absence of any warranty; and give any other recipients of
the Program a copy of this License along with the Program. You may charge a fee for the
physical act of transferring a copy, and you may at your option offer warranty protection in
exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a
work based on the Program, and copy and distribute such modifications or work under the
terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed
the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains
or is derived from the Program or any part thereof, to be licensed as a whole at no charge
to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must
cause it, when started running for such interactive use in the most ordinary way, to print or
display an announcement including an appropriate copyright notice and a notice that there
is no warranty (or else, saying that you provide a warranty) and that users may redistribute
the program under these conditions, and telling the user how to view a copy of this License.
(Exception: if the Program itself is interactive but does not normally print such an
announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that
work are not derived from the Program, and can be reasonably considered independent and
separate works in themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you distribute the same
sections as part of a whole which is a work based on the Program, the distribution of the
whole must be on the terms of this License, whose permissions for other licensees extend to
the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written
entirely by you; rather, the intent is to exercise the right to control the distribution of
derivative or collective works based on the Program. In addition, mere aggregation of
another work not based on the Program with the Program (or with a work based on the
Program) on a volume of a storage or distribution medium does not bring the other work
under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in
object code or executable form under the terms of Sections 1 and 2 above provided that
you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a medium customarily
used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party,
for a charge no more than your cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be distributed under the terms
of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for noncommercial distribution
and only if you received the program in object code or executable form with such an offer,
in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications
to it. For an executable work, complete source code means all the source code for all
modules it contains, plus any associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a special exception, the
source code distributed need not include anything that is normally distributed (in either
source or binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself accompanies
the executable.
If distribution of executable or object code is made by offering access to copy from a
designated place, then offering equivalent access to copy the source code from the same
place counts as distribution of the source code, even though third parties are not compelled
to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly
provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute
the Program is void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However,
nothing else grants you permission to modify or distribute the Program or its derivative
works. These actions are prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the Program), you indicate
your acceptance of this License to do so, and all its terms and conditions for copying,
distributing or modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the
recipient automatically receives a license from the original licensor to copy, distribute or
modify the Program subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein. You are not responsible
for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any
other reason (not limited to patent issues), conditions are imposed on you (whether by
court order, agreement or otherwise) that contradict the conditions of this License, they do
not excuse you from the conditions of this License. If you cannot distribute so as to satisfy
simultaneously your obligations under this License and any other pertinent obligations, then
as a consequence you may not distribute the Program at all. For example, if a patent license
would not permit royalty-free redistribution of the Program by all those who receive copies
directly or indirectly through you, then the only way you could satisfy both it and this
License would be to refrain entirely from distribution of the Program. If any portion of this
section is held invalid or unenforceable under any particular circumstance, the balance of
the section is intended to apply and the section as a whole is intended to apply in other
circumstances. It is not the purpose of this section to induce you to infringe any patents or
other property right claims or to contest validity of any such claims; this section has the
sole purpose of protecting the integrity of the free software distribution system, which is
implemented by public license practices. Many people have made generous contributions to
the wide range of software distributed through that system in reliance on consistent
application of that system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose that choice. This
section is intended to make thoroughly clear what is believed to be a consequence of the
rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by
patents or by copyrighted interfaces, the original copyright holder who places the Program
under this License may add an explicit geographical distribution limitation excluding those
countries, so that distribution is permitted only in or among countries not thus excluded. In
such case, this License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General
Public License from time to time. Such new versions will be similar in spirit to the present
version, but may differ in detail to address new problems or concerns. Each version is given
a distinguishing version number. If the Program specifies a version number of this License
which applies to it and "any later version", you have the option of following the terms and
conditions either of that version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of this License, you may
choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose
distribution conditions are different, write to the author to ask for permission. For software
which is copyrighted by the Free Software Foundation, write to the Free Software
Foundation; we sometimes make exceptions for this. Our decision will be guided by the two
goals of preserving the free status of all derivatives of our free software and of promoting
the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO
THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM
PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO
LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the
public, the best way to achieve this is to make it free software which everyone can
redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start
of each source file to most effectively convey the exclusion of warranty; and each file should
have at least the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.> Copyright (C)
<year> <name of author>
This program is free software; you can redistribute it and/or modify it under the terms of
the GNU General Public License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY;
without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR
PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with this program;
if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA
02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an
interactive mode:
Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with
ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are
welcome to redistribute it under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of
the General Public License. Of course, the commands you use may be called something
other than `show w' and `show c'; they could even be mouse-clicks or menu items-whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to
sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the
names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which
makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into proprietary
programs. If your program is a subroutine library, you may consider it more useful to permit
linking proprietary applications with the library. If this is what you want to do, use the GNU
Library General Public License instead of this License.
