It support analog tv,DVB-T and radio in a single chip. The chip has been used in several dongles, such as aeromax DH-9000: http://www.b2bdvb.com/dh-9000.htm You can get more info from: [1] http://www.telegent.com/ [2] http://www.telegent.com/press/2009Sept14_CSI.html The driver is based Mauro's subtree(2.6.33-rc4). about country code: The country code is needed for firmware, so I can not remove it. If I remove it, the audio will not work properly. about hibernate: My test environment: PC: dell vostro 200, 2G RAM, dual core 2G OS: Fedora 12 (kernel is compiled with Mauro's subtree, 2.6.33-rc4) my test shell script: ------- file begin ------------- " echo shutdown > /sys/power/disk" " echo disk > /sys/power/state" ------- file end ------------- the test result: [1] ANALOG TV : video runs well after hibernate,but alsa system did not resume the snd_pcm_substream. [2] DVB-T : runs profectly. [3] FM: Mplayer will be terminated for the long delay of hibernate makes it close the audio. This is not a problem, just re-open it. v1 --> v2 : [1] use the videobuf-vmalloc,remove old queue code. [2] change the V4L2 implementation, use the videobuf-core's code. [3] optimize the power management code. [4] misc bugs. Huang Shijie (10): add header files for tlg2300 add the generic file add video/vbi file for tlg2300 add DVB-T support for tlg2300 add FM support for tlg2300 add audio support for tlg2300 add document file for tlg2300 add Kconfig and Makefile for tlg2300 modify the Kconfig and Makefile for tlg2300 add maintainers for tlg2300 Documentation/video4linux/README.tlg2300 | 231 +++++ MAINTAINERS | 8 + drivers/media/video/Kconfig | 2 + drivers/media/video/Makefile | 1 + drivers/media/video/tlg2300/Kconfig | 16 + drivers/media/video/tlg2300/Makefile | 9 + drivers/media/video/tlg2300/pd-alsa.c | 332 ++++++ drivers/media/video/tlg2300/pd-common.h | 280 +++++ drivers/media/video/tlg2300/pd-dvb.c | 593 +++++++++++ drivers/media/video/tlg2300/pd-main.c | 566 ++++++++++ drivers/media/video/tlg2300/pd-radio.c | 351 +++++++ drivers/media/video/tlg2300/pd-video.c | 1648 ++++++++++++++++++++++++++++++ drivers/media/video/tlg2300/vendorcmds.h | 243 +++++ 13 files changed, 4280 insertions(+), 0 deletions(-) create mode 100644 Documentation/video4linux/README.tlg2300 create mode 100644 drivers/media/video/tlg2300/Kconfig create mode 100644 drivers/media/video/tlg2300/Makefile create mode 100644 drivers/media/video/tlg2300/pd-alsa.c create mode 100644 drivers/media/video/tlg2300/pd-common.h create mode 100644 drivers/media/video/tlg2300/pd-dvb.c create mode 100644 drivers/media/video/tlg2300/pd-main.c create mode 100644 drivers/media/video/tlg2300/pd-radio.c create mode 100644 drivers/media/video/tlg2300/pd-video.c create mode 100644 drivers/media/video/tlg2300/vendorcmds.h ^ permalink raw reply [flat|nested] 18+ messages in thread

I'm assuming that you're referring to the analog part, right? Instead of a country code, the driver should use the V4L2_STD_ macros to determine the audio standard. Please take a look at saa7134-tvaudio code. It has an interesting logic to associate the V4L2_STD with the corresponding audio settings: For example, the audio carrier frequency and the audio standard are at tvaudio array: static struct saa7134_tvaudio tvaudio[] = { { .name = "PAL-B/G FM-stereo", .std = V4L2_STD_PAL_BG, .mode = TVAUDIO_FM_BG_STEREO, .carr1 = 5500, .carr2 = 5742, },{ .name = "PAL-D/K1 FM-stereo", .std = V4L2_STD_PAL_DK, .carr1 = 6500, .carr2 = 6258, .mode = TVAUDIO_FM_BG_STEREO, },{ .name = "PAL-D/K2 FM-stereo", .std = V4L2_STD_PAL_DK, .carr1 = 6500, .carr2 = 6742, .mode = TVAUDIO_FM_BG_STEREO, },{ .name = "PAL-D/K3 FM-stereo", .std = V4L2_STD_PAL_DK, .carr1 = 6500, .carr2 = 5742, .mode = TVAUDIO_FM_BG_STEREO, },{ .name = "PAL-B/G NICAM", .std = V4L2_STD_PAL_BG, .carr1 = 5500, .carr2 = 5850, .mode = TVAUDIO_NICAM_FM, },{ .name = "PAL-I NICAM", .std = V4L2_STD_PAL_I, .carr1 = 6000, .carr2 = 6552, .mode = TVAUDIO_NICAM_FM, },{ .name = "PAL-D/K NICAM", .std = V4L2_STD_PAL_DK, .carr1 = 6500, .carr2 = 5850, .mode = TVAUDIO_NICAM_FM, },{ .name = "SECAM-L NICAM", .std = V4L2_STD_SECAM_L, .carr1 = 6500, .carr2 = 5850, .mode = TVAUDIO_NICAM_AM, },{ ... } Btw, probably the most complicated device, in terms of firmware, is the xc3028. It has one different firmware for each different combination of standard. There are 80 different firmwares at the version 3.6. Each time a firmware changes, a reset via GPIO should be sent to the device. The tuner-xc3028 has a logic that re-loads the firmware if the standard changes, and the new standard is not supported by the current firmware. So, it may help if you also take a look at tuner-xc2028. -- Cheers, Mauro ^ permalink raw reply [flat|nested] 18+ messages in thread

In the case of radio, the frequency ranges are controlled via the tuner ioctls. There's no standard way to control the preemphasis, but I recommend adding a ctrl to select between 50us/75us and no preemphasis. -- Cheers, Mauro ^ permalink raw reply [flat|nested] 18+ messages in thread

No, I don't meant that. The differences of FM radio standards are basically the preemphasis and the frequency ranges. For frequency ranges, V4L2_TUNER_RADIO allows specifying the maximum/minimum values. For preemphasis, you should implement V4L2_CID_TUNE_PREEMPHASIS ctrl. This CTRL has 3 states: static const char *tune_preemphasis[] = { "No preemphasis", "50 useconds", "75 useconds", NULL, }; At v4l2-common.c, there are some functions that helps to implement it at the driver, like: v4l2_ctrl_get_menu, v4l2_ctrl_get_name and v4l2_ctrl_query_fill. Take a look at si4713-i2c.c for an example on how to use it. Ah, please submit those changes as another series of patches. This helps me to not needing to review the entire changeset again.

Unfortunately, userspace applications take some time to follow kernel changes. Yet, there are a few generic applications for it, both hosted together with the v4l-dvb mercurial tree: v4l2-ctl and qv4l2. On both applications, the controls are retrieved dynamically. In particular, v4l2-ctl is a command-line application. So, you may call it when the device is detected (for example, by udev) or before starting the application. This is very useful with dumb applications that doesn't give full control over the device. For example, I use it on my environment to pre-adjust my webcam to give a clearer image, when using on skype, with this script: export LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so v4l2-ctl -cexposure=1000 v4l2-ctl -cwhite_balance=47 export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype.real $_ > [2] I do not know how to use the VLC to listen the radio with ALSA, I > tried many times, but failed. Does someone know this ? I've no idea. Never tried vlc for radio here. > Btw: I will be on my vacation for the following two weeks, I will come > back to > work at 20th of this month. I afraid I can not finish the patches to > remove the > country code in the two days(today and tomorrow). -rc7 is about to be released. So, it is late for 2.6.33 cycle. I think we'll have -rc8 again, as there were several changes at drm/nouveau/x86 arch. I may be wrong though. Assuming that I did a good guess, we'll have +2 weeks for the next merge window. Also, as this is a new driver, if we miss the merge window, we may try to submit it for -rc1 or -rc2. So, providing that, on your return, you focus on it, I think it would be possible to have it added for 2.6.34. -- Cheers, Mauro ^ permalink raw reply [flat|nested] 18+ messages in thread
