Sony BDV-T20W User Manual

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.

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.
