24 * Let's call the version 0.... until compression decoding is completely
25 * implemented.
26 *
27 * This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
28 * It was based on USB CPiA driver written by Peter Pregler,
29 * Scott J. Bertin and Johannes Erdfelt
30 * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &

44 * (Thanks to Giovanni Garberoglio)
45 *
46 * Added: UK Hauppauge WinTV-USB Vendor ID: 0x0573
47 * Product ID: 0x4D02
48 * (Thanks to Derek Freeman-Jones)
49 *
50 * Feb, 2001 - Apr 08, 2001: (0.3.0)
51 * - Some fixes. Driver is now more stable.
52 * - Scratch is organized as ring-buffer now for better performance
53 * - DGA (overlay) is now supported.
54 * !!!!Danger!!!! Clipping is not yet implemented. Your system will
55 * crash if your video window leaves the screen!!!
56 * - Max. Framesize is set to 320x240. There isn't more memory on the
57 * nt1003 video device for the FIFO.
58 * - Supported video palettes: RGB565, RGB555, RGB24, RGB32
59 *
60 *
61 * Apr 15, 2001: (0.3.1-test...)
62 * - Clipping is implemented
63 * - NTSC is now coloured (Thanks to Dwaine Garden)
64 * - Added SECAM colour detection in saa7111-new
65 * - Added: French Hauppauge WinTV USB Vendor ID: 0x0573
66 * Product ID: 0x4D03
67 * (Thanks to Julius Hrivnac)
68 * - Added: US Hauppauge WINTV USB Vendor ID: 0x0573
69 * Product ID: 0x4D00
70 * (Thanks to Derrick J Brashear)

72 * Adding your devices data to the usbvision_device_data table is all
73 * you need to add a new device.
74 *
75 * May 11, 2001: (0.3.2-test...) (Thanks to Derek Freeman-Jones)
76 * - Support YUV422 raw format for people with hardware scaling.
77 * - Only power on the device when opened (use option PowerOnAtOpen=0 to disable it).
78 * - Turn off audio so we can listen to Line In.
79 *
80 * July 5, 2001 - (Patch the driver to run with Kernel 2.4.6)
81 * - Fixed a problem with the number of parameters passed to video_register_device.
82 *
83 * July 6, 2001 - Added: HAUPPAUGE WINTV-USB FM USA Vendor ID: 0x0573

95 * - Checked the audio channels and mute for HAUPPAUGE WinTV USB FM
96 * - Implemented the power on when opening the device. But some software opens
97 * the device several times when starting. So the i2c parts are just registered
98 * by an open, when they become deregistered by the next close. You can speed
99 * up tuner detection, when adding "options tuner addr=your_addr" to /etc/modules.conf
100 * - Begin to resize the frame in width and height. So it will be possible to watch i.e.
101 * 384x288 pixels at 23 fps.

302 * -Updated makefile to put compiled modules into correct location.
303 *
304 * Aug 21, 2006 - 0.9.8.3cvs Dwaine
305 * -Changed number of bytes for i2c write to 4 as per the NT100X spec sheet. Thanks to Merlum for finding it.
306 * -Remove the radio option for device Hauppauge WinTV USB device Model 40219 Rev E189. This device does not have a FM radio. Thanks to Shadwell.
307 * -Added radio option for device Hauppauge WinTV USB device Model 40219 Rev E189 again. Just got an e-mail indicating their device has one. 8*)
308 *
309 * Aug 27, 2006 - 0.9.8.3cvs Dwaine
310 * -Changed ifdef statement so the usbvision driver will compile with kernels at 2.6.12.
311 * -Updated readme files for new updated tuner list for v4l devices.
312 *
313 *
314 *
315 * TODO:
316 * - use submit_urb for all setup packets
317 * - Fix memory settings for nt1004. It is 4 times as big as the
318 * nt1003 memory.
319 * - Add audio on endpoint 3 for nt1004 chip. Seems impossible, needs a codec interface. Which one?
320 * - Clean up the driver.
321 * - optimization for performance.
322 * - Add Videotext capability (VBI). Working on it.....
323 * - Check audio for other devices
324 * - Add v4l2 interface
325 *

27 * This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
28 * It was based on USB CPiA driver written by Peter Pregler,
29 * Scott J. Bertin and Johannes Erdfelt
30 * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &

34 *
35 * TODO:
36 * - use submit_urb for all setup packets
37 * - Fix memory settings for nt1004. It is 4 times as big as the
38 * nt1003 memory.
39 * - Add audio on endpoint 3 for nt1004 chip. Seems impossible, needs a codec interface. Which one?
40 * - Clean up the driver.
41 * - optimization for performance.
42 * - Add Videotext capability (VBI). Working on it.....
43 * - Check audio for other devices
