Digital  channels  have  a  Physical,  Major,  and  Minor channel  number.  The  Physical  number  is  the  actual digital channel number, the Major is the number that the  channel  should  be  mapped  to,  and  the  Minor  is the sub-channel. Since the ATSC tuner automatically maps the channel to the Major number, the Physical number is not required when sending a command.Data 00: Physical Channel NumberNTSC air: 02~45, NTSC cable: 01, 0E~7DATSC air: 01~45, ATSC cable: 01~87Data 01 & 02: Major Channel NumberData 01: High byte  Data 02: Low byteTwo  bytes  are  available  for  the  Major  and  Minor,

Most cases  just  use  0  since  it’s  ignored  when  using NTSC.* 5th  bit:  Use  0  with  NTSC  since  it  can  only  use the  physical  channel  number.

							GNU GENE\bAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software 
Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-
1301, USA
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 
Lesser 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.
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.

OPEN SOU\bCE LICENSE  
						

							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

							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.
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.

							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.

							For example, if you distribute copies of the library, 
whether gratis or for a fee, you must give the 
recipients all the rights that we gave you. You 
must make sure that they, too, receive or can get 
the source code. If you link other code with the 
library, you must provide complete object files to 
the recipients, so that they can relink them with 
the library after making changes to the library and 
recompiling it. And you must show them these 
terms so they know their rights. 
We protect your rights with a two-step method: (1) 
we copyright the library, and (2) we offer you this 
license, which gives you legal permission to copy, 
distribute and/or modify the library. 
To protect each distributor, we want to make it 
very clear that there is no warranty for the free 
library. Also, if the library is modified by someone 
else and passed on, the recipients should know 
that what they have is not the original version, 
so that the original author’s reputation will not be 
affected by problems that might be introduced by 
others. 
Finally, software patents pose a constant threat 
to the existence of any free program. We wish 
to make sure that a company cannot effectively 
restrict the users of a free program by obtaining a 
restrictive license from a patent holder. Therefore, 
we insist that any patent license obtained for a 
version of the library must be consistent with the 
full freedom of use specified in this license. 
Most GNU software, including some libraries, 
is covered by the ordinary GNU General Public 
License. This license, the GNU Lesser General 
Public License, applies to certain designated 
libraries, and is quite different from the ordinary 
General Public License. We use this license for 
certain libraries in order to permit linking those 
libraries into non-free programs. 
When a program is linked with a library, whether 
statically or using a shared library, the combination 
of the two is legally speaking a combined work, 
a derivative of the original library. The ordinary 
General Public License therefore permits such 
linking only if the entire combination fits its criteria 
of freedom. The Lesser General Public License 
permits more lax criteria for linking other code 
with the library.

Preamble
The licenses for most software are designed to 
take away your freedom to share and change it. 
By contrast, the GNU General Public Licenses are 
intended to guarantee your freedom to share and 
change free software--to make sure the software 
is free for all its users. 
This license, the Lesser General Public License, 
applies to some specially designated software 
packages--typically libraries--of the Free Software 
Foundation and other authors who decide to 
use it. You can use it too, but we suggest you 
first think carefully about whether this license or 
the ordinary General Public License is the better 
strategy to use in any particular case, based on the 
explanations below. 
When we speak of free software, we are referring 
to freedom of use, 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 and use pieces 
of it in new free programs; and that you are 
informed that you can do these things.
To protect your rights, we need to make 
restrictions that forbid distributors to deny you 
these rights or to ask you to surrender these 
rights. These restrictions translate to certain 
responsibilities for you if you distribute copies of 
the library or if you modify it.

							We call this license the “Lesser” General Public 
License because it does Less to protect the user’s 
freedom than the ordinary General Public License. 
It also provides other free software developers 
Less of an advantage over competing non-free 
programs. These disadvantages are the reason we 
use the ordinary General Public License for many 
libraries. However, the Lesser license provides 
advantages in certain special circumstances. 
For example, on rare occasions, there may be a 
special need to encourage the widest possible use 
of a certain library, so that it becomes a de-facto 
standard. To achieve this, non-free programs must 
be allowed to use the library. A more frequent 
case is that a free library does the same job as 
widely used non-free libraries. In this case, there 
is little to gain by limiting the free library to free 
software only, so we use the Lesser General 
Public License. 
In other cases, permission to use a particular 
library in non-free programs enables a greater 
number of people to use a large body of free 
software. For example, permission to use the GNU 
C Library in non-free programs enables many more 
people to use the whole GNU operating system, 
as well as its variant, the GNU/Linux operating 
system. 
Although the Lesser General Public License 
is Less protective of the users’ freedom, it 
does ensure that the user of a program that is 
linked with the Library has the freedom and the 
wherewithal to run that program using a modified 
version of the Library. 
The precise terms and conditions for copying, 
distribution and modification follow. Pay close 
attention to the difference between a “work based 
on the library” and a “work that uses the library”. 
The former contains code derived from the library, 
whereas the latter must be combined with the 
library in order to run. 
TERMS AND CONDITIONS FOR COPYING, 
DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software 
library or other program which contains a 
notice placed by the copyright holder or other 
authorized party saying it may be distributed 
under the terms of this Lesser General Public 
License (also called “this License”). Each 
licensee is addressed as “you”.
A “library” means a collection of software 
functions and/or data prepared so as to be 
conveniently linked with application programs 
(which use some of those functions and data) 
to form executables. 
The “Library”, below, refers to any such 
software library or work which has been 
distributed under these terms. A “work based 
on the Library” means either the Library or any 
derivative work under copyright law: that is to 
say, a work containing the Library or a portion 
of it, either verbatim or with modifications and/
or translated straightforwardly into another 
language. (Hereinafter, translation is included 
without limitation in the term “modification”.) 
“Source code” for a work means the preferred 
form of the work for making modifications to 
it. For a library, 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 library.
Activities other than copying, distribution and 
modification are not covered by this License; 
they are outside its scope. The act of running a 
program using the Library is not restricted, and 
output from such a program is covered only 
if its contents constitute a work based on the 
Library (independent of the use of the Library 
in a tool for writing it). Whether that is true 
depends on what the Library does and what the 
program that uses the Library does. 
1. You may copy and distribute verbatim copies 
of the Library’s complete 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 distribute a copy 
of this License along with the Library. 
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.
