+                    GNU GENERAL 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.
+
+                    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.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser General
+Public License instead of this License.

+/* According to ETSI EN 302 307 5.5.4 the PLS (Physical Layer
+   Scrambling) for DVB-S2 consists of a complex randomization
+   sequence which is ultimately derived from two recursively
+   defined m-sequences  (=MLS or maximum length sequences)
+   x(i) and y(i) of polynomials over GF(2) with m=18
+   (thus their length is 2^18 - 1).
+   These m-sequences with sequence y starting from y(0) and
+   sequence x starting from x(n) are combined to form a set
+   of 2^18 - 1 different Gold code sequences.
+
+   This starting number n of sequence x selects which
+   of those 2^18 - 1 Gold code sequences to use.
+   As a DVB-S2 tuning parameter n is called the scrambling sequence index 
+   (cf. ETSI EN 300 468 table 41) or Gold sequence index,
+   commonly also just called "Gold code".
+   The 18 values of the sequence x starting from x(n)
+   (x(n) ... x(n+17)) are also called the "Root code".
+   So, Gold and Root codes are not different ways of PLS, they are
+   just different ways to select the same sequence start point.
+     
+   The initial values for x(i), i=0..18 are x(0)=1, x(1)=0, .., x(17)=0 .  
+   The polynomial used for the x sequence recursion is 1+x^7+x^18.
+   If the lower 18 bits of a variable "uint32_t X" contain x(n) ... x(n+17),
+   then we can simply calculate x(n+1) ... x(n+18) by doing:
+   X = (((X ^ (X >> 7)) & 1) << 17) | (X >> 1);
+  
+   So, if X contained the "Root code" corresponding to "Gold code" n,
+   it will now contain the "Root code" corresponding to "Gold code" (n+1).
+   Note that X=0 and n=2^18 - 1 do not exist (or rather the lattter is the same
+   as n = 0) and for n=0 to 2^18 - 2 and X=1 to 2^18 - 1 there is a
+   one-to-one correspondence (bijection).
+
+   Note that PLS has nothing to do with encryption for DRM purposes. It is used
+   to minimize interference between transponders.
+
+
+   "Combo code":
+   There is no such thing as a combo code. It is the result of a bug in older
+   STV090x drivers which resulted in a crazy race condition between a Gold->Root
+   conversion in the STV and an ongoing I2C write. 
+   Better forget about it and determine the proper Root or Gold code.

+To allow the transport of DVB-S2 baseband frames (BBFrame) across existing hard- and software
+interfaces, we have added the ability to embed the BBFrame data into
+an MPEG2 transport stream.
+
+This feature is available on supported cards as firmware update and
+is currently considered experimental.
+
+Supported hardware:
+
+Cine V7A                  (>=1.7 FW)
+OctopusCI S2 Pro Advanced (>=1.7 FW)
+Duoflex S2 v4 Advanced    (TBA)
+MaxSX8                    (NOT the MAXS8!)
+
+The following cards are based on the broadcast version of the
+DVB-S2 demodulator. The BBFrame output is working but
+not documented. We therefore can not guarantee the
+feature will work under all conditions.
+
+cineS2 V7              (>=1.7 FW)
+OctopusCI S2 Pro       (>=1.7 FW)
+Duoflex S2 v4          (TBA)
+
+
+Current FPGA images (including FW 1.7 for the above mentioned cards)
+can be found here:
+
+http://download.digital-devices.de/download/firmware/html/firmwareupdate.html
+
+
+
+Packet format:
+
+The BBFrames are packetized into MPEG2 private sections (0x80), one section per transport stream
+packet. The PID is fixed at 0x010E.
+
+
+Header packet of frame:
+
+0x47 0x41 0x0E 0x1X 0x00 0x80 0x00 L 0xB8 BBHeader (169 * Data)
+
+L: Section Length, always 180 (0xB4)
+BBHeader: 10 Bytes BBFrame header (see DVB-S2, EN-302307)
+Data: 169 Bytes of BBFrame payload
+
+
+Payload packets:
+
+0x47 0x41 0x0E 0x1X 0x00 0x80 0x00 L N (179 * Data)
+
+L: Section Length, always 180 (0xB4)
+N: Packet counter, starting with 0x01 after header packet
+Data: 179 Bytes of BBFrame payload
+
+
+Last packet:
+0x47 0x41 0x0E 0x1X 0x00 0x80 0x00 L N ((L-1) * Data)  ((180 – L) * 0xFF)
+
+L: Section Length, remaining Data – 1, (0x01 .. 0xB4)
+N: Packet counter
+Data: L-1 Bytes of BBFrame payload
+
+
+
+Automatic detection of input format:
+
+The bridge firmware allows automatic detection of the incoming data.
+To receive regular transport streams in this formats it is still required to setup
+the DVB-S2 demodulator to output BBFrames instead of regular TS Packets.
+When enabled the embedding mode is automatically turned on or off depending on incoming data
+from the DVB-S2/S2X frontend. The decision depends currently only on the first byte of a packet.
+If it is 0x47 it switches to transport stream mode else it switches to embedding mode.
+
+Note that 0x47 can currently not occur in the first byte of a BBFrame header if all reserved
+values of DVB-S2 and -S2X are observed.
+
+
+
+
+API:
+
+Currently DTV_STREAM_ID is misused.
+Set it to 0x80000000 to enable frame mode in the demod.
+
+
+
+Because there were some questions why we use this data format,
+here are some examples for why using this format this makes handling BBFrames easier:
+
+- The start of a frame is easily found  because a new set of sections is
+  started. 
+  
+- Existing software layers like the Linux kernel DVB demuxer can be used unchanged.
+
+- Existing hardware like the OctopusNet SAT>IP server which can only handle TS packets can
+  stream BBFrames via SAT>IP with this method.
+
+- There is at least one demodulator (e.g. on the MaxSX8) which supports this format in hardware.

 For testing one can use a standard application that

+into cable by the modulator.
+
+
+
+The modulator device can be controlled with the
+following properties:
+
+MODULATOR_FREQUENCY:
+
+Set the frequency on Version 2 (FSM) cards
+units - Hz
+range - 114000000-874000000
+allowed values - 114 + 8000000*X
+
+For older cards you have to use the
+DVB_MOD_SET ioctl.
+
+
+
+MODULATOR_SYMBOLRATE:
+
+Set the symbol rate
+units - Hz
+range - Version 1 cards: only 6900000
+        Version 2 cards(FSM): X-7100000
+
+
+MODULATOR_MODULATION:
+
+Set the modulation type
+range: QAM_16 .. QAM_256
+
+
+
+MODULATOR_ATTENUATION:
+
+range - 0-31
+unit  - 1 dB
+
+
+MODULATOR_GAIN:
+
+range - 0-255
+unit  - 0.125 dB
+
+
+The MODULATOR_ATTENUATOR is based on a switched resistor network,
+also it is backward compatible to our old modulator.
+the MODULATOR_GAIN is based on a variable gain amplifier, so it is less
+accurate then the attenuator.
+High gain values will drive the output amplifier into clipping. The
+limit depends on # of channels active.
+
+
+
+
+MODULATOR_INPUT_BITRATE:
+
+The modulator will ALWAY insert null packets if it
+does not get enough data.
+If you specify the input bitrate it will insert additional
+null packets according to the difference between input
+and output bit rate.
+The latter is determined by symbol rte and modulation.
+So, this property should be set last.
+
+unit - 2^-32 Hz
+
+
+
+Debugging features:
+
+MODULATOR_STATUS and MODULATOR_RESET have been added to debug
+possible problems with too high temperatures (overtemperature)
+or PLL lock loss on FSM type cards.
+
+The MODULATOR_STATUS property returns a __u32 with the following status bits:
+
+- bit 0  : Lock status 1=lock OK, 0 = lock lost
+
+- bit 1  : Sticky lock lost indicator
+           0 = no PLL lock loss since last status read
+	   1 = lock has been lost since last status read 
+
+- bit 2  : 0 = no overtemperature
+           1 = overtemperature detected
+
+- bit 4  : 0 = PCIe link OK
+           1 = PCIe link lost
+
+In case of overtemperratur or PCIe link loss you will have to reboot the PC.
+
+
+Putting a MODULATOR_STATUS property with value 2 will enable the lost lock
+interrupt. This will set the gain to 0 and the attenuation to 31 in case
+of a lost PLL lock.
+
+
+The MODULATOR_RESET property can be used to reset the modulator without
+needing to reload the driver or rebooting in case of PLL lock loss.
+All channels should be stopped before using it and restarted after using it.
+Otherwise, results are unpredictable.

+ * @buffer2_length:	Length of the TS data in buffer2.
+ * @source:		Indicates which TS feed is the source of the callback.
+ *
+ * This function callback prototype, provided by the client of the demux API,
+ * is called from the demux code. The function is only called when filtering
+ * on a TS feed has been enabled using the start_filtering\(\) function at
+ * the &dmx_demux.
+ * Any TS packets that match the filter settings are copied to a circular
+ * buffer. The filtered TS packets are delivered to the client using this
+ * callback function.
+ * It is expected that the @buffer1 and @buffer2 callback parameters point to
+ * addresses within the circular buffer, but other implementations are also
+ * possible. Note that the called party should not try to free the memory
+ * the @buffer1 and @buffer2 parameters point to.
+ *
+ * When this function is called, the @buffer1 parameter typically points to
+ * the start of the first undelivered TS packet within a circular buffer.
+ * The @buffer2 buffer parameter is normally NULL, except when the received
+ * TS packets have crossed the last address of the circular buffer and
+ * "wrapped" to the beginning of the buffer. In the latter case the @buffer1
+ * parameter would contain an address within the circular buffer, while the
+ * @buffer2 parameter would contain the first address of the circular buffer.
+ * The number of bytes delivered with this function (i.e. @buffer1_length +
+ * @buffer2_length) is usually equal to the value of callback_length parameter
+ * given in the set() function, with one exception: if a timeout occurs before
+ * receiving callback_length bytes of TS data, any undelivered packets are
+ * immediately delivered to the client by calling this function. The timeout
+ * duration is controlled by the set() function in the TS Feed API.
+ *
+ * If a TS packet is received with errors that could not be fixed by the
+ * TS-level forward error correction (FEC), the Transport_error_indicator
+ * flag of the TS packet header should be set. The TS packet should not be
+ * discarded, as the error can possibly be corrected by a higher layer
+ * protocol. If the called party is slow in processing the callback, it
+ * is possible that the circular buffer eventually fills up. If this happens,
+ * the demux driver should discard any TS packets received while the buffer
+ * is full and return -EOVERFLOW.
+ *
+ * The type of data returned to the callback can be selected by the
+ * &dmx_ts_feed.@set function. The type parameter decides if the raw
+ * TS packet (TS_PACKET) or just the payload (TS_PACKET|TS_PAYLOAD_ONLY)
+ * should be returned. If additionally the TS_DECODER bit is set the stream
+ * will also be sent to the hardware MPEG decoder.

-**     routines are called. For example:
-**
-**     *** write <buflen> bytes ***
-**     free = dvb_ringbuffer_free(rbuf);
-**     if (free >= buflen)
-**         count = dvb_ringbuffer_write(rbuf, buffer, buflen);
-**     else
-**         ...
-**
-**     *** read min. 1000, max. <bufsize> bytes ***
-**     avail = dvb_ringbuffer_avail(rbuf);
-**     if (avail >= 1000)
-**         count = dvb_ringbuffer_read(rbuf, buffer, min(avail, bufsize));
-**     else
-**         ...
-**
-** (2) If there is exactly one reader and one writer, there is no need
-**     to lock read or write operations.
-**     Two or more readers must be locked against each other.
-**     Flushing the buffer counts as a read operation.
-**     Resetting the buffer counts as a read and write operation.
-**     Two or more writers must be locked against each other.
