+PVR350 Video decoder registers 0x02002800 -> 0x02002B00
+=======================================================
+
+This list has been worked out through trial and error. There will be mistakes
+and omissions. Some registers have no obvious effect so it's hard to say what
+they do, while others interact with each other, or require a certain load
+sequence. Horizontal filter setup is one example, with six registers working
+in unison and requiring a certain load sequence to correctly configure. The
+indexed colour palette is much easier to set at just two registers, but again
+it requires a certain load sequence.
+
+Some registers are fussy about what they are set to. Load in a bad value & the
+decoder will fail. A firmware reload will often recover, but sometimes a reset
+is required. For registers containing size information, setting them to 0 is
+generally a bad idea. For other control registers i.e. 2878, you'll only find
+out what values are bad when it hangs.

+      bits 0:31
+	Decoder horizontal Y alias register 5
+---------------
+2818
+      bits 0:31
+	Decoder horizontal Y alias trigger
+
+     These six registers control the horizontal aliasing filter for the Y plane.
+     The first five registers must all be loaded before accessing the trigger
+     (2818), as this register actually clocks the data through for the first
+     five.
+
+     To correctly program set the filter, this whole procedure must be done 16
+     times. The actual register contents are copied from a lookup-table in the
+     firmware which contains 4 different filter settings.

+---------------
+2830
+      bits 0:31
+	Decoder horizontal UV alias trigger
+
+     These six registers control the horizontal aliasing for the UV plane.
+     Operation is the same as the Y filter, with 2830 being the trigger
+     register.

+2834
+      bits 0:15
+	Decoder Y source width in pixels
+
+      bits 16:31

+---------------
+2838
+      bits 0:15
+	Decoder UV source width in pixels
+
+      bits 16:31
+	Decoder UV destination width in pixels
+
+     NOTE: For both registers, the resulting image must be fully visible on
+     screen. If the image exceeds the right edge both the source and destination
+     size must be adjusted to reflect the visible portion. For the source width,
+     you must take into account the scaling when calculating the new value.

+	Decoder ?? unknown
+	  Normally = Reg 2854 >> 1
+---------------
+2868
+      bits 0:31
+	Decoder ?? unknown
+	  Usually 0
+
+     Most of these registers either control horizontal scaling, or appear linked
+     to it in some way. Register 2854 contains the 'master' value & the other
+     registers can be calculated from that one. You must also remember to
+     correctly set the divider in Reg 2874.
+
+     To enlarge:
+	     Reg 2854 = (source_width * 0x00200000) / destination_width
+	     Reg 2874 = No divide
+
+     To reduce from full size down to half size:
+	     Reg 2854 = (source_width/2 * 0x00200000) / destination width
+	     Reg 2874 = Divide by 2
+
+     To reduce from half size down to quarter size:
+	     Reg 2854 = (source_width/4 * 0x00200000) / destination width
+	     Reg 2874 = Divide by 4
+
+     The result is always rounded up.

+286C
+      bits 0:15
+	Decoder horizontal Y buffer offset
+
+      bits 15:31
+	Decoder horizontal UV buffer offset
+
+     Offset into the video image buffer. If the offset is gradually incremented,
+     the on screen image will move left & wrap around higher up on the right.

+2870
+      bits 0:15
+	Decoder horizontal Y output offset
+
+      bits 16:31
+	Decoder horizontal UV output offset
+
+     Offsets the actual video output. Controls output alignment of the Y & UV
+     planes. The higher the value, the greater the shift to the left. Use
+     reg 2890 to move the image right.

+	  Moves entire screen horizontally. Starts at 0x005 with the screen

+	  gradually shift the screen to the left.
+
+      bits 11:31

+
+     Warning: Bad values will require a firmware reload to recover.

+--------------------------------------------------------------------------------
+288C
+      bits 0:15
+	osd ?? unknown
+	  Appears to affect the osd position stability. The higher the value the
+	  more unstable it becomes. Decoder output remains stable.
+
+      bits 16:31
+	osd ?? unknown
+	  Same as bits 0:15
+
+--------------------------------------------------------------------------------
+2890
+      bits 0:11
+	Decoder output horizontal offset.
+
+     Horizontal offset moves the video image right. A small left shift is
+     possible, but it's better to use reg 2870 for that due to its greater
+     range.
+
+     NOTE: Video corruption will occur if video window is shifted off the right
+     edge. To avoid this read the notes for 2834 & 2838.
+--------------------------------------------------------------------------------
+2894
+      bits 0:23
+	Decoder output video surround colour.
+
+     Contains the colour (in yuv) used to fill the screen when the video is
+     running in a window.
+--------------------------------------------------------------------------------
+2898
+      bits 0:23
+	Decoder video window colour
+	  Contains the colour (in yuv) used to fill the video window when the
+	  video is turned off.
+
+      bit 24
+	Decoder video output
+	  0 = Video on
+	  1 = Video off
+
+      bit 28
+	Decoder plane order
+	  0 = Y,UV
+	  1 = UV,Y
+
+      bit 29
+	Decoder second plane byte order
+	  0 = Normal (UV)
+	  1 = Swapped (VU)
+
+     In normal usage, the first plane is Y & the second plane is UV. Though the
+     order of the planes can be swapped, only the byte order of the second plane
+     can be swapped. This isn't much use for the Y plane, but can be useful for
+     the UV plane.

+289C
+      bits 0:15
+	Decoder vertical field offset 1
+
+      bits 16:31
+	Decoder vertical field offset 2
+
+     Controls field output vertical alignment. The higher the number, the lower
+     the image on screen. Known starting values are 0x011E0017 (NTSC) &
+     0x01500017 (PAL)
+--------------------------------------------------------------------------------
+28A0
+      bits 0:15
+	Decoder & osd width in pixels
+
+      bits 16:31
+	Decoder & osd height in pixels
+
+     All output from the decoder & osd are disabled beyond this area. Decoder
+     output will simply go black outside of this region. If the osd tries to
+     exceed this area it will become corrupt.
+--------------------------------------------------------------------------------
+28A4
+      bits 0:11
+	osd left shift.
+
+     Has a range of 0x770->0x7FF. With the exception of 0, any value outside of
+     this range corrupts the osd.
+--------------------------------------------------------------------------------
+28A8
+      bits 0:15
+	osd vertical field offset 1
+
+      bits 16:31
+	osd vertical field offset 2
+
+     Controls field output vertical alignment. The higher the number, the lower
+     the image on screen. Known starting values are 0x011E0017 (NTSC) &
+     0x01500017 (PAL)

+      bits 0:31
+	Decoder vertical Y alias register 2
+---------------
+2908
+      bits 0:31
+	Decoder vertical Y alias trigger
+
+     These three registers control the vertical aliasing filter for the Y plane.
+     Operation is similar to the horizontal Y filter (2804). The only real
+     difference is that there are only two registers to set before accessing
+     the trigger register (2908). As for the horizontal filter, the values are
+     taken from a lookup table in the firmware, and the procedure must be
+     repeated 16 times to fully program the filter.
+--------------------------------------------------------------------------------
+290C
+      bits 0:31
+	Decoder vertical UV alias register 1
+---------------

+      bits 0:31
+	Decoder vertical UV alias register 2
+---------------
+2914
+      bits 0:31
+	Decoder vertical UV alias trigger
+
+     These three registers control the vertical aliasing filter for the UV
+     plane. Operation is the same as the Y filter, with 2914 being the trigger.
+--------------------------------------------------------------------------------
+2918
+      bits 0:15
+	Decoder Y source height in pixels
+
+      bits 16:31
+	Decoder Y destination height in pixels
+---------------
+291C
+      bits 0:15
+	Decoder UV source height in pixels divided by 2
+
+      bits 16:31
+	Decoder UV destination height in pixels
+
+     NOTE: For both registers, the resulting image must be fully visible on
+     screen. If the image exceeds the bottom edge both the source and
+     destination size must be adjusted to reflect the visible portion. For the
+     source height, you must take into account the scaling when calculating the
+     new value.

+      bits 0:31
+	Decoder ?? unknown - UV vertical scaling
+
+     Most of these registers either control vertical scaling, or appear linked
+     to it in some way. Register 2930 contains the 'master' value & all other
+     registers can be calculated from that one. You must also remember to
+     correctly set the divider in Reg 296C
+
+     To enlarge:
+	     Reg 2930 = (source_height * 0x00200000) / destination_height
+	     Reg 296C = No divide
+
+     To reduce from full size down to half size:
+	     Reg 2930 = (source_height/2 * 0x00200000) / destination height
+	     Reg 296C = Divide by 2
+
+      To reduce from half down to quarter.
+	     Reg 2930 = (source_height/4 * 0x00200000) / destination height
+	     Reg 296C = Divide by 4

+
+     When the bits-per-pixel is set to 8, the colour mode is ignored and
+     assumed to be 8 bit indexed. For 16 & 32 bits-per-pixel the colour depth
+     is honoured, and when using a colour depth that requires fewer bytes than
+     allocated the extra bytes are used as padding. So for a 32 bpp with 8 bit
+     index colour, there are 3 padding bytes per pixel. It's also possible to
+     select 16bpp with a 32 bit colour mode. This results in the pixel width
+     being doubled, but the color key will not work as expected in this mode.
+
+     Colour key is as it suggests. You designate a colour which will become
+     completely transparent. When using 565, 555 or 444 colour modes, the
+     colour key is always 16 bits wide. The colour to key on is set in Reg 2A18.
+
+     Local alpha is a per-pixel 256 step transparency, with 0 being transparent
+     and 255 being solid. This is only available in 32 bit & 8 bit indexed
+     colour modes.
+
+     Global alpha is a 256 step transparency that applies to the entire osd,
+     with 0 being transparent & 255 being solid.
+
+     It's possible to combine colour key, local alpha & global alpha.
