Support Digital Video Broadcasting hardware. Enable this if you
own a DVB adapter and want to use it or if you compile Linux for
a digital SetTopBox.
API specs and user tools are available from <http://www.linuxtv.org/>.
Please report problems regarding this driver to the LinuxDVB
mailing list.
If unsure say N.

Support for PCI cards based on the Bt8xx PCI bridge. Examples are
the Nebula cards, the Pinnacle PCTV cards, the Twinhan DST cards,
the pcHDTV HD2000 cards, the DViCO FusionHDTV Lite cards, and
some AVerMedia cards.
Since these cards have no MPEG decoder onboard, they transmit
only compressed MPEG data over the PCI bus, so you need
an external software decoder to watch TV on your computer.
Say Y if you own such a device and want to use it.

config DVB_CINERGYT2
tristate "Terratec CinergyT2/qanu USB2 DVB-T receiver"
depends on DVB_CORE && USB
help
Support for "TerraTec CinergyT2" USB2.0 Highspeed DVB Receivers
Say Y if you own such a device and want to use it.
config DVB_CINERGYT2_TUNING
bool "sophisticated fine-tuning for CinergyT2 cards"
depends on DVB_CINERGYT2
help
Here you can fine-tune some parameters of the CinergyT2 driver.
Normally you don't need to touch this, but in exotic setups you
may fine-tune your setup and adjust e.g. DMA buffer sizes for
a particular application.
config DVB_CINERGYT2_STREAM_URB_COUNT
int "Number of queued USB Request Blocks for Highspeed Stream Transfers"
depends on DVB_CINERGYT2_TUNING
default "32"
help
USB Request Blocks for Highspeed Stream transfers are scheduled in
a queue for the Host Controller.
Usually the default value is a safe choice.
You may increase this number if you are using this device in a
Server Environment with many high-traffic USB Highspeed devices
sharing the same USB bus.
config DVB_CINERGYT2_STREAM_BUF_SIZE
int "Size of URB Stream Buffers for Highspeed Transfers"
depends on DVB_CINERGYT2_TUNING
default "512"
help
Should be a multiple of native buffer size of 512 bytes.
Default value is a safe choice.
You may increase this number if you are using this device in a
Server Environment with many high-traffic USB Highspeed devices
sharing the same USB bus.
config DVB_CINERGYT2_QUERY_INTERVAL
int "Status update interval [milliseconds]"
depends on DVB_CINERGYT2_TUNING
default "250"
help
This is the interval for status readouts from the demodulator.
You may try lower values if you need more responsive signal quality
measurements.
Please keep in mind that these updates cause traffic on the tuner
control bus and thus may or may not affect reception sensitivity.
The default value should be a safe choice for common applications.
config DVB_CINERGYT2_ENABLE_RC_INPUT_DEVICE
bool "Register the onboard IR Remote Control Receiver as Input Device"
depends on DVB_CINERGYT2_TUNING
default y
help
Enable this option if you want to use the onboard Infrared Remote
Control Receiver as Linux-Input device.
Right now only the keycode table for the default Remote Control
delivered with the device is supported, please see the driver
source code to find out how to add support for other controls.
config DVB_CINERGYT2_RC_QUERY_INTERVAL
int "Infrared Remote Controller update interval [milliseconds]"
depends on DVB_CINERGYT2_TUNING && DVB_CINERGYT2_ENABLE_RC_INPUT_DEVICE
default "50"
help
If you have a very fast-repeating remote control you can try lower
values, for normal consumer receivers the default value should be
a safe choice.

help
DVB core utility functions for device handling, software fallbacks etc.
Say Y when you have a DVB card and want to use it. Say Y if your want
to build your drivers outside the kernel, but need the DVB core. All
in-kernel drivers will select this automatically if needed.
If unsure say N.
config DVB_CORE_ATTACH
bool "Load and attach frontend modules as needed"
depends on DVB_CORE
depends on MODULES
help
Remove the static dependency of DVB card drivers on all
frontend modules for all possible card variants. Instead,
allow the card drivers to only load the frontend modules
they require. This saves several KBytes of memory.
Note: You will need module-init-tools v3.2 or later for this feature.
If unsure say Y.

** ------

** 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), 0);
** 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.
** Two or more writers must be locked against each other.

/* DVB USB compliant linux driver for Conexant USB reference design.
*
* The Conexant reference design I saw on their website was only for analogue
* capturing (using the cx25842). The box I took to write this driver (reverse
* engineered) is the one labeled Medion MD95700. In addition to the cx25842
* for analogue capturing it also has a cx22702 DVB-T demodulator on the main
* board. Besides it has a atiremote (X10) and a USB2.0 hub onboard.
*
* Maybe it is a little bit premature to call this driver cxusb, but I assume
* the USB protocol is identical or at least inherited from the reference
* design, so it can be reused for the "analogue-only" device (if it will
* appear at all).
*
* TODO: Use the cx25840-driver for the analogue part
