   Transmission  [m][a][  ][Set  ID][  ][Data00][  ][Data01]   [ ][Data02][ ][Data03][ ][Data04][ ][Data05][Cr]
   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 Number
             NTSC air: 02 - 45, NTSC cable: 01, 0E - 7D
             ATSC air: 01 - 45, ATSC cable: 01 - 87
 Data 01 & 02:   
Major Channel Number 
 Data 01: High byte                    Data 02: Low byte
        Two  bytes  are  available  for  the  Major  and  Minor, normally only the second byte is used. 
 Data 03 & 04: Minor Channel Number 
                            Not needed for NTSC.

   The  table  above  lists  the  binary  code  which  must  be converted to Hexadecimal before sending. For exam-ple:  The  binary  code  to  tune  the  sub  source  to  an NTSC cable channel is “1000 0001”, which translates to “81” in Hex.
    *   
7th bit : For which source do you want to change the channel.
    *   
6th  bit:  Use  a  two  part  or  one  part  channel.  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.  Normally  use  1  for  ATSC since most times it doesn’t  matter what the physical number is.
    * 4th bit: Set to 0.
    * 3-0 bits: Choose signal type.
   * Tune Command Examples:
 1.  Tune to the analog (NTSC) cable channel 35.
      Data  00 = Physical of 35 = 23
     Data 01 & 02 = No Major = 00 00
     Data 03 & 04 = No Minor = 00 00
     Data 05 = 0000 0001 in binary = 01
     Total = ma 00 23 00 00 00 00 01
 2.  Tune to the digital local channel 30-3.
      Data  00 = Don’t know Physical = 00
     Data 01 & 02 = Major is 30 = 00 1E
     Data 03 & 04 = Minor is 3 = 00 03
     Data 05 = 0010 0010 in binary = 22
     Total = ma 00 00 00 1E 00 03 22

OPEN SOURCE LICENSE
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 cop-ies 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 free-dom 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  cov-ered  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  free-dom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute cop-ies 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 sur-render  the  rights.  These  restrictions  translate  to  certain responsibilities  for  you  if  you  distribute  copies  of  the  soft-ware, 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 origi-nal authors' reputations.
Finally,  any  free  program  is  threatened  constantly  by  soft-ware patents. We wish to avoid the danger that redistribu-tors of a free program will individually obtain patent licens-es,  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 LICENSETERMS 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 modi-fications  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 modifica-tion 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 (inde-pendent 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 pub-lish  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  pro-tection 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.
