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.

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.

NOTE: For both registers, the resulting image must be fully visible on

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.

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.

--------------------------------------------------------------------------------
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.
--------------------------------------------------------------------------------

Contains the colour (in yuv) used to fill the screen when the video is
running in a window.

Decoder video window colour
Contains the colour (in yuv) used to fill the video window when the
video is turned 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.

output will simply go black outside of this region. If the osd tries to
exceed this area it will become corrupt.

---------------
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.

NOTE: For both registers, the resulting image must be fully visible on

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.

This driver attempts to support the video interface of the devices mounting the
SONiX SN9C101, SN9C102 and SN9C103 PC Camera Controllers.
It's worth to note that SONiX has never collaborated with the author during the
development of this project, despite several requests for enough detailed
specifications of the register tables, compression engine and video data format

The driver relies on the Video4Linux2 and USB core modules. It has been

11. Video frame formats [1]
=======================
The SN9C10x PC Camera Controllers can send images in two possible video
formats over the USB: either native "Sequential RGB Bayer" or Huffman
compressed. The latter is used to achieve high frame rates. The current video
format may be selected or queried from the user application by calling the
VIDIOC_S_FMT or VIDIOC_G_FMT ioctl's, as described in the V4L2 API
specifications.
The SN9C1xx PC Camera Controllers can send images in two possible video
formats over the USB: either native "Sequential RGB Bayer" or compressed.
The compression is used to achieve high frame rates. With regard to the
SN9C101, SN9C102 and SN9C103, the compression is based on the Huffman encoding
algorithm described below, while the SN9C105 and SN9C120 the compression is
based on the JPEG standard.
The current video format may be selected or queried from the user application

One compressed video frame consists of a bitstream that encodes for every R, G,
or B pixel the difference between the value of the pixel itself and some
reference pixel value. Pixels are organised in the Bayer pattern and the Bayer
sub-pixels are tracked individually and alternatingly. For example, in the
first line values for the B and G1 pixels are alternatingly encoded, while in
the second line values for the G2 and R pixels are alternatingly encoded.

To use the driver, it is necessary to load the "zc0301" module into memory
after every other module required: "videodev", "usbcore" and, depending on
the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd".
