-<H3>Reading Images</H3>
-Each call to the <b>read</b> syscall returns the next available image
-from the device. It is up to the caller to set format and size (using
-the VIDIOCSPICT and VIDIOCSWIN ioctls) and then to pass a suitable
-size buffer and length to the function. Not all devices will support
-read operations.
-<P>
-A second way to handle image capture is via the mmap interface if supported.
-To use the mmap interface a user first sets the desired image size and depth
-properties. Next the VIDIOCGMBUF ioctl is issued. This reports the size
-of buffer to mmap and the offset within the buffer for each frame. The
-number of frames supported is device dependent and may only be one.
-<P>
-The video_mbuf structure contains the following fields
-<P>
-<TABLE>
-<TR><TD><b>size</b><TD>The number of bytes to map</TD>
-<TR><TD><b>frames</b><TD>The number of frames</TD>
-<TR><TD><b>offsets</b><TD>The offset of each frame</TD>
-</TABLE>
-<P>
-Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the
-capture to a frame using the format and image size specified in the
-video_mmap (which should match or be below the initial query size).
-When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em>
-captured yet, the driver just instructed the hardware to start the
-capture. The application has to use the VIDIOCSYNC ioctl to wait
-until the capture of a frame is finished. VIDIOCSYNC takes the frame
-number you want to wait for as argument.
-<p>
-It is allowed to call VIDIOCMCAPTURE multiple times (with different
-frame numbers in video_mmap->frame of course) and thus have multiple
-outstanding capture requests. A simple way do to double-buffering
-using this feature looks like this:
-<pre>
-/* setup everything */
-VIDIOCMCAPTURE(0)
-while (whatever) {
- VIDIOCMCAPTURE(1)
- VIDIOCSYNC(0)
- /* process frame 0 while the hardware captures frame 1 */
- VIDIOCMCAPTURE(0)
- VIDIOCSYNC(1)
- /* process frame 1 while the hardware captures frame 0 */
-}
-</pre>
-Note that you are <em>not</em> limited to only two frames. The API
-allows up to 32 frames, the VIDIOCGMBUF ioctl returns the number of
-frames the driver granted. Thus it is possible to build deeper queues
-to avoid loosing frames on load peaks.
-<p>
-While capturing to memory the driver will make a "best effort" attempt
-to capture to screen as well if requested. This normally means all
-frames that "miss" memory mapped capture will go to the display.
-<P>
-A final ioctl exists to allow a device to obtain related devices if a
-driver has multiple components (for example video0 may not be associated
-with vbi0 which would cause an intercast display program to make a bad
-mistake). The VIDIOCGUNIT ioctl reports the unit numbers of the associated
-devices if any exist. The video_unit structure has the following fields.
-<P>
-<TABLE>
-<TR><TD><b>video</b><TD>Video capture device</TD>
-<TR><TD><b>vbi</b><TD>VBI capture device</TD>
-<TR><TD><b>radio</b><TD>Radio device</TD>

-</TABLE>
-<P>
-<H3>RDS Datastreams</H3>
-For radio devices that support it, it is possible to receive Radio Data
-System (RDS) data by means of a read() on the device. The data is packed in
-groups of three, as follows:
-<TABLE>
-<TR><TD>First Octet</TD><TD>Least Significant Byte of RDS Block</TD></TR>
-<TR><TD>Second Octet</TD><TD>Most Significant Byte of RDS Block
-<TR><TD>Third Octet</TD><TD>Bit 7:</TD><TD>Error bit. Indicates that
-an uncorrectable error occurred during reception of this block.</TD></TR>
-<TR><TD>&nbsp;</TD><TD>Bit 6:</TD><TD>Corrected bit. Indicates that
-an error was corrected for this data block.</TD></TR>
-<TR><TD>&nbsp;</TD><TD>Bits 5-3:</TD><TD>Received Offset. Indicates the
-offset received by the sync system.</TD></TR>
