+1.1 What the TV decoder can do an what not
+------------------------------------------
+
+The best know TV standards are NTSC/PAL/SECAM. but for decoding a frame that
+information is not enough. There are several formats of the TV standards.
+And not every TV decoder is able to handle every format. Also the every
+combination is supported by the driver. There are currently 11 different
+tv broadcast formats all aver the world.
+
+The CCIR defines parameters needed for broadcasting the signal.
+The CCIR has defined different standards: A,B,D,E,F,G,D,H,I,K,K1,L,M,N,...
+The CCIR says not much about the colorsystem used !!!
+And talking about a colorsystem says not to much about how it is broadcast.
+
+The CCIR standards A,E,F are not used any more.
+
+When you speak about NTSC, you usually mean the standard: CCIR - M using
+the NTSC colorsystem which is used in the USA, Japan, Mexico, Canada
+and a few others.
+
+When you talk about PAL, you usually mean: CCIR - B/G using the PAL
+colorsystem which is used in many Countries.
+
+When you talk about SECAM, you mean: CCIR - L using the SECAM Colorsystem
+which is used in France, and a few others.
+
+There the other version of SECAM, CCIR - D/K is used in Bulgaria, China,
+Slovakai, Hungary, Korea (Rep.), Poland, Rumania and a others.
+
+The CCIR - H uses the PAL colorsystem (sometimes SECAM) and is used in
+Egypt, Libya, Sri Lanka, Syrain Arab. Rep.
+
+The CCIR - I uses the PAL colorsystem, and is used in Great Britain, Hong Kong,
+Ireland, Nigeria, South Africa.
+
+The CCIR - N uses the PAL colorsystem and PAL frame size but the NTSC framerate,
+and is used in Argentinia, Uruguay, an a few others
+
+We do not talk about how the audio is broadcast !
+
+A rather good sites about the TV standards are:
+http://www.sony.jp/support/
+http://info.electronicwerkstatt.de/bereiche/fernsehtechnik/frequenzen_und_normen/Fernsehnormen/
+and http://www.cabl.com/restaurant/channel.html
+
+Other weird things around: NTSC 4.43 is a modificated NTSC, which is mainly
+used in PAL VCR's that are able to play back NTSC. PAL 60 seems to be the same
+as NTSC 4.43 . The Datasheets also talk about NTSC 44, It seems as if it would
+be the same as NTSC 4.43.
+NTSC Combs seems to be a decoder mode where the decoder uses a comb filter
+to split coma and luma instead of a Delay line.
+
+But I did not defiantly find out what NTSC Comb is.

+to generate PAL N, maybe it would work if you use the PAL M settings.
+
+How do I get this damn thing to work
+------------------------------------
+
+Load zr36067.o. If it can't autodetect your card, use the card=X insmod
+option with X being the card number as given in the previous section.
+To have more than one card, use card=X1[,X2[,X3,[X4[..]]]]
+
+To automate this, add the following to your /etc/modprobe.d/zoran.conf:
+
+options zr36067 card=X1[,X2[,X3[,X4[..]]]]
+alias char-major-81-0 zr36067
+
+One thing to keep in mind is that this doesn't load zr36067.o itself yet. It
+just automates loading. If you start using xawtv, the device won't load on
+some systems, since you're trying to load modules as a user, which is not
+allowed ("permission denied"). A quick workaround is to add 'Load "v4l"' to
+XF86Config-4 when you use X by default, or to run 'v4l-conf -c <device>' in
+one of your startup scripts (normally rc.local) if you don't use X. Both
+make sure that the modules are loaded on startup, under the root account.
+
+What mainboard should I use (or why doesn't my card work)
+---------------------------------------------------------
+
+
+<insert lousy disclaimer here>. In short: good=SiS/Intel, bad=VIA.
+
+Experience tells us that people with a Buz, on average, have more problems
+than users with a DC10+/LML33. Also, it tells us that people owning a VIA-
+based mainboard (ktXXX, MVP3) have more problems than users with a mainboard
+based on a different chipset. Here's some notes from Andrew Stevens:
+
+Here's my experience of using LML33 and Buz on various motherboards:
+
+- VIA MVP3
+ - Forget it. Pointless. Doesn't work.
+- Intel 430FX (Pentium 200)
+ - LML33 perfect, Buz tolerable (3 or 4 frames dropped per movie)
+- Intel 440BX (early stepping)
+ - LML33 tolerable. Buz starting to get annoying (6-10 frames/hour)
+- Intel 440BX (late stepping)
+ - Buz tolerable, LML3 almost perfect (occasional single frame drops)
+- SiS735
+ - LML33 perfect, Buz tolerable.
+- VIA KT133(*)
+ - LML33 starting to get annoying, Buz poor enough that I have up.
+
+- Both 440BX boards were dual CPU versions.
+
+Bernhard Praschinger later added:
+
+- AMD 751
+ - Buz perfect-tolerable
+- AMD 760
+ - Buz perfect-tolerable
+
+In general, people on the user mailinglist won't give you much of a chance
+if you have a VIA-based motherboard. They may be cheap, but sometimes, you'd
+rather want to spend some more money on better boards. In general, VIA
+mainboard's IDE/PCI performance will also suck badly compared to others.
+You'll noticed the DC10+/DC30+ aren't mentioned anywhere in the overview.
+Basically, you can assume that if the Buz works, the LML33 will work too. If
+the LML33 works, the DC10+/DC30+ will work too. They're most tolerant to
+different mainboard chipsets from all of the supported cards.
+
+If you experience timeouts during capture, buy a better mainboard or lower
+the quality/buffersize during capture (see 'Concerning buffer sizes, quality,
+output size etc.'). If it hangs, there's little we can do as of now. Check
+your IRQs and make sure the card has its own interrupts.
+
+Programming interface
+---------------------
+
+This driver conforms to video4linux2. Support for V4L1 and for the custom
+zoran ioctls has been removed in kernel 2.6.38.
+
+For programming example, please, look at lavrec.c and lavplay.c code in
+the MJPEG-tools (http://mjpeg.sf.net/).
+
+Additional notes for software developers:
+
+ The driver returns maxwidth and maxheight parameters according to
+ the current TV standard (norm). Therefore, the software which
+ communicates with the driver and "asks" for these parameters should
+ first set the correct norm. Well, it seems logically correct: TV
+ standard is "more constant" for current country than geometry
+ settings of a variety of TV capture cards which may work in ITU or
+ square pixel format.
+
+Applications
+------------
+
+Applications known to work with this driver:
+
+TV viewing:
+
+* xawtv
+* kwintv
+* probably any TV application that supports video4linux or video4linux2.
+
+MJPEG capture/playback:
+
+* mjpegtools/lavtools (or Linux Video Studio)
+* gstreamer
+* mplayer
+
+General raw capture:
+
+* xawtv
+* gstreamer
+* probably any application that supports video4linux or video4linux2
+
+Video editing:
+
+* Cinelerra
+* MainActor
+* mjpegtools (or Linux Video Studio)
+
+
+Concerning buffer sizes, quality, output size etc.
+--------------------------------------------------
+
+
+The zr36060 can do 1:2 JPEG compression. This is really the theoretical
+maximum that the chipset can reach. The driver can, however, limit compression
+to a maximum (size) of 1:4. The reason for this is that some cards (e.g. Buz)
+can't handle 1:2 compression without stopping capture after only a few minutes.
+With 1:4, it'll mostly work. If you have a Buz, use 'low_bitrate=1' to go into
+1:4 max. compression mode.
+
+100% JPEG quality is thus 1:2 compression in practice. So for a full PAL frame
+(size 720x576). The JPEG fields are stored in YUY2 format, so the size of the
+fields are 720x288x16/2 bits/field (2 fields/frame) = 207360 bytes/field x 2 =
+414720 bytes/frame (add some more bytes for headers and DHT (huffman)/DQT
+(quantization) tables, and you'll get to something like 512kB per frame for
+1:2 compression. For 1:4 compression, you'd have frames of half this size.
+
+Some additional explanation by Martin Samuelsson, which also explains the
+importance of buffer sizes:
+--
+> Hmm, I do not think it is really that way. With the current (downloaded
+> at 18:00 Monday) driver I get that output sizes for 10 sec:
+> -q 50 -b 128 : 24.283.332 Bytes
+> -q 50 -b 256 : 48.442.368
+> -q 25 -b 128 : 24.655.992
+> -q 25 -b 256 : 25.859.820
+
+I woke up, and can't go to sleep again. I'll kill some time explaining why
+this doesn't look strange to me.
+
+Let's do some math using a width of 704 pixels. I'm not sure whether the Buz
+actually use that number or not, but that's not too important right now.
+
+704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block;
+3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block;
+1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum
+output becomes 512 bits per block. Actually 510, but 512 is simpler to use
+for calculations.
+
+Let's say that we specify d1q50. We thus want 256 bits per block; times 3168
+becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes
+here, so we don't need to do any fancy corrections for bits-per-pixel or such
+things. 101376 bytes per field.
+
+d1 video contains two fields per frame. Those sum up to 202752 bytes per
+frame, and one of those frames goes into each buffer.
+
+But wait a second! -b128 gives 128kB buffers! It's not possible to cram
+202752 bytes of JPEG data into 128kB!
+
+This is what the driver notice and automatically compensate for in your
+examples. Let's do some math using this information:
+
+128kB is 131072 bytes. In this buffer, we want to store two fields, which
+leaves 65536 bytes for each field. Using 3168 blocks per field, we get
+20.68686868... available bytes per block; 165 bits. We can't allow the
+request for 256 bits per block when there's only 165 bits available! The -q50
+option is silently overridden, and the -b128 option takes precedence, leaving
+us with the equivalence of -q32.
+
+This gives us a data rate of 165 bits per block, which, times 3168, sums up
+to 65340 bytes per field, out of the allowed 65536. The current driver has
+another level of rate limiting; it won't accept -q values that fill more than
+6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be
+a safe bet. Personally, I think I would have lowered requested-bits-per-block
+by one, or something like that.) We can't use 165 bits per block, but have to
+lower it again, to 6/8 of the available buffer space: We end up with 124 bits
+per block, the equivalence of -q24. With 128kB buffers, you can't use greater
+than -q24 at -d1. (And PAL, and 704 pixels width...)
+
+The third example is limited to -q24 through the same process. The second
+example, using very similar calculations, is limited to -q48. The only
+example that actually grab at the specified -q value is the last one, which
+is clearly visible, looking at the file size.
+--
+
+Conclusion: the quality of the resulting movie depends on buffer size, quality,
+whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c
+module to do 1:4 instead of 1:2 compression, etc.
+
+If you experience timeouts, lowering the quality/buffersize or using
+'low_bitrate=1 as insmod option for zr36060.o might actually help, as is
+proven by the Buz.
+
+It hangs/crashes/fails/whatevers! Help!
+---------------------------------------
+
+Make sure that the card has its own interrupts (see /proc/interrupts), check
+the output of dmesg at high verbosity (load zr36067.o with debug=2,
+load all other modules with debug=1). Check that your mainboard is favorable
+(see question 2) and if not, test the card in another computer. Also see the
+notes given in question 3 and try lowering quality/buffersize/capturesize
+if recording fails after a period of time.
+
+If all this doesn't help, give a clear description of the problem including
+detailed hardware information (memory+brand, mainboard+chipset+brand, which
+MJPEG card, processor, other PCI cards that might be of interest), give the
+system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give
+the kernel version, driver version, glibc version, gcc version and any other
+information that might possibly be of interest. Also provide the dmesg output
+at high verbosity. See 'Contacting' on how to contact the developers.

+/* general description */
+/* =================== */
+
+/* Should ease the (re-)usage of drivers supporting cards with (different)
+ video codecs. The codecs register to this module their functionality,
+ and the processors (masters) can attach to them if they fit.
+
+ The codecs are typically have a "strong" binding to their master - so I
+ don't think it makes sense to have a full blown interfacing as with e.g.
+ i2c. If you have an other opinion, let's discuss & implement it :-)))
+
+ Usage:
+
+ The slave has just to setup the videocodec structure and use two functions:
+ videocodec_register(codecdata);
+ videocodec_unregister(codecdata);
+ The best is just calling them at module (de-)initialisation.
+
+ The master sets up the structure videocodec_master and calls:
+ codecdata=videocodec_attach(master_codecdata);
+ videocodec_detach(codecdata);
+
+ The slave is called during attach/detach via functions setup previously
+ during register. At that time, the master_data pointer is set up
+ and the slave can access any io registers of the master device (in the case
+ the slave is bound to it). Otherwise it doesn't need this functions and
+ therfor they may not be initialized.
+
+ The other functions are just for convenience, as they are for sure used by
+ most/all of the codecs. The last ones may be omitted, too.
+
+ See the structure declaration below for more information and which data has
+ to be set up for the master and the slave.
+
+ ----------------------------------------------------------------------------
+ The master should have "knowledge" of the slave and vice versa. So the data
+ structures sent to/from slave via set_data/get_data set_image/get_image are
+ device dependent and vary between MJPEG/MPEG/WAVELET/... devices. (!!!!)

+ ==== master setup ====
+ name -> name of the device structure for reference and debugging
+ master_data -> data ref. for the master (e.g. the zr36055,57,67)
+ readreg -> ref. to read-fn from register (setup by master, used by slave)
+ writereg -> ref. to write-fn to register (setup by master, used by slave)
+ this two functions do the lowlevel I/O job
+
+ ==== slave functionality setup ====
+ slave_data -> data ref. for the slave (e.g. the zr36050,60)
+ check -> fn-ref. checks availability of an device, returns -EIO on failure or
+ the type on success
+ this makes espcecially sense if a driver module supports more than
+ one codec which may be quite similar to access, nevertheless it
+ is good for a first functionality check
+
+ -- main functions you always need for compression/decompression --
+
+ set_mode -> this fn-ref. resets the entire codec, and sets up the mode
+ with the last defined norm/size (or device default if not
+ available) - it returns 0 if the mode is possible
+ set_size -> this fn-ref. sets the norm and image size for
+ compression/decompression (returns 0 on success)
+ the norm param is defined in videodev2.h (V4L2_STD_*)
+
+ additional setup may be available, too - but the codec should work with
+ some default values even without this
+
+ set_data -> sets device-specific data (tables, quality etc.)
+ get_data -> query device-specific data (tables, quality etc.)
+
+ if the device delivers interrupts, they may be setup/handled here
+ setup_interrupt -> codec irq setup (not needed for 36050/60)
+ handle_interrupt -> codec irq handling (not needed for 36050/60)
+
+ if the device delivers pictures, they may be handled here
+ put_image -> puts image data to the codec (not needed for 36050/60)
+ get_image -> gets image data from the codec (not needed for 36050/60)
+ the calls include frame numbers and flags (even/odd/...)
+ if needed and a flag which allows blocking until its ready

+ * in this function (and one or two others in zoran_device.c)
