I've tested with other ATSC tuners just to confirm, using:

Anyhow, as it turns out, the tuner-xc2028 *does* require a tuning offset
for ATSC. Even though the linux-dvb api passes in center frequencies
from userspace, apparantly the xceive firmware is already factoring in
the tuning offset to center.

This patch should fix the 'muted audio' and 'raspy audio' problem for
mpeg2 streams out of cx88-blackbird devices.
Especially mythtv users would find that the audio would often sound bad
(aliased, or 'raspy'), mainly related to channel changes, many (all?)
other users would find that there was no audio at all in the mpeg data
from the encoder chip, unless the audio was manually unmuted.
The patch includes the following modifications:
Don't actually start the mpeg2 encoder until the device is read from
by the application.
Wait until the audio is stable for at least 400ms before starting the
mpeg encoder.
Mute/Unmute the audio when starting/stopping the mpeg encoder.
Stop the mpeg encoder when changing parameters and when changing tuner
frequency.
Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of
whether or not the mpeg2 encoder is active.

Previously, all yuv data written to /dev/video48 had only basic support with
no double buffering to avoid display tearing.
With this patch, yuv frames written to video48 are now handled by the existing
IVTV_IOC_DMA_FRAME framework. As such, the frames are hardware buffered to
avoid tearing, and honour scaling mode & field order options. Unlike the
proprietary IVTV_IOC_DMA_FRAME ioctl, all parameters are controlled by the
V4L2 API.
Due to mpeg & yuv output restrictions being different, their V4L2 output
controls have been separated. To control the yuv output, the V4L2 calls must
be done via video48.
If the ivtvfb module is loaded, there will be one side effect to this merge.
The yuv output window will be constrained to the visible framebuffer area. In
the event that a virtual framebuffer size is being used, the limit to the
output size will be the virtual dimensions, but only the portion that falls
within the currently visible area of the framebuffer will be shown.
Like the IVTV_IOC_DMA_FRAME ioctl, the supplied frames must be padded to 720
pixels wide. However the height must only be padded up the nearest multiple
of 32. This would mean an image of 102 lines must be padded to 128. As long
as the true source image size is given, the padding will not be visible in
the final output.

Interlace mode selection code moved into the frame setup phase, so it's now
run before the frame is loaded into a hardware buffer. Given that it can
affect how a new frame is displayed, it was a bit stupid running it after the
frame was already visible.
A few stray interlace related variables which were linked to individual frames
have now been moved into the yuv_frame_info struct. This means that all
variables linked to a specific frame are in the same place & not scattered.
Minor code reformatting in areas touched by the above changes.

To reduce the number of display register accesses, the yuv code keeps track of
the current video settings. Should there be a change in any single parameter,
it will update the associated display registers to ensure everything is
displayed correctly.
The existing check also looks at the field order for the video. This is not
required, since field reversal does not require any display register changes.
This patch removes the field order from the check.

Currently the yuv output stream buffer is divided into blocks whose size
depend on the broadcast standard selected during the driver init phase.
However, the standard can be changed after the init phase. This effectively
breaks the yuv output stream handler, since it relies on the different yuv
planes being block aligned.
This patch changes the setup, so that the block size is always the same. The
decoder dma function has been modified to cope with the fact that the second
yuv plane may no longer be block aligned. The start of the yuv frame must
still be at the beginning of a block, so the stream write function has also
been modified to ensure this is always true.
Also, the stream write function will now initiate a yuv dma transfer as soon
as a full frame is ready. It will not wait until the current write request
has completed, or the stream buffer becomes full.

For Hauppauge 24xxx devices, the IR receiver is a custom piece of
logic that is very specific to the device. The pvrusb2 driver can
virtualize this to make it look like a more normal IR receiver found
in other Hauppauge devices. The decision of whether or not to enable
this virtualization however is a device-specific attribute, thus this

The exact routing of video and audio signals within a device is a
device-specific attribute. Hauppauge devices do it one way; other
types of device may route things differently. Unfortunately it is
rather impractical to define chip-specific routing at the device
attribute level, so instead what happens here is that "schemes" are
defined. Each chip level interface implements its part of a given
scheme and the scheme as a whole is made into a device specific
attribute controlled via a table entry in pvrusb2-devattr.c. The only
scheme defined here is for Hauppauge devices, but clearly this opens
the door for other possibilities to follow.

This is a new implementation for video pipeline control within the
pvrusb2 driver. Actual start/stop of the pipeline is moved to the
driver's kernel thread. Pipeline stages are controlled autonomously
based on surrounding pipeline or application control state. Kernel
thread management is also cleaned up and moved into the internal
control structure of the driver, solving a set up / tear down race
along the way. Better failure recovery is implemented with this new
control strategy. Also with this change comes better control of the
cx23416 encoder, building on additional information learned about the
peculiarities of controlling this part (this information was the
original trigger for this rework). With this change, overall encoder
stability should be considerably improved. Yes, this is a large
change for this driver, but due to the nature of the feature being
worked on, the changes are fairly pervasive and would be difficult to
break into smaller pieces with any semblence of step-wise stability.

But these mostly hybrid tuners are not fully backward compatible, since
they must power down and mute regardless.

to the TV input is functional and backward compatible for the applications,
