I use tvtime and mplayer to view ATSC and NTSC content OTA. I have the same input for both and prefer not to split it due to loss. Anyways, with 2.6.24 series and below the drivers seems to pick the inputs 'properly' for my needs. Now they don't. I looked through the source and it seems that things are being structured more sanely.

I have the following output when I set debug=1 for tuner_simple and run 'mplayer dvb://',

tuner-simple 1-0061: using tuner params #1 (digital)
tuner-simple 1-0061: freq = 509.00 (8144), range = 2, config = 0xc6, cb = 0x44 tuner-simple 1-0061: Philips TUV1236D ATSC/NTSC dual in: div=8848 | buf=0x22,0x90,0xc6,0x44

I don't get any output when running either tvtime or 'mplayer tv://'. Is there some userspace ioctl call that should be made to set the antenna input for NTSC content? I also tried setting the atv_input and dtv_input values. This didn't seem to change anything.

I started getting lost in the code. Why does simple_std_setup() check for V4L2_STD_ATSC and then unconditionally use atv_input? Maybe that simple_set_rf_input() is undone at a later time?

Thanks for any info. Search engines are sparse with information on tuner_simple parameter information. Although I expect I need some code that does ioctls to the tuner modules.

Bill Pringlemeir.

Hi
I believe you want use module options for tuner_simple. To my knowledge
this can be set only at module load, Specifically atv_input and dtv_input for analog and digital respectfully,

KWorld ATSC 110 and NTSC [was: 2.6.25+ and KWorld ATSC 110 inputs]

In reply to Bill Pringlemeir

I have experimented with this a bit further. Here are some of my observations,

I switch the antenna feed between top and bottom inputs with no effect on getting the NTSC signal.

Loading with a 2.6.24 (non-SMP) kernel and rebooting will allow the NTSC signals to be found by tvtime and mplayer. Running mplayer with 'dvb://' losses the NTSC signals. I was booting *without* module support previously. My kernel is now SMP with power support (I believe that 2.6.27 is the first kernel with SMP, but I had other kernels that seemed to also break the NTSC without SMP).

I change my 2.6.27.7 kernel to use modules for the saa7134. On advice from others I used the /etc/modprobe.d and created a v4l.local file,

install tuner_simple modprobe -i tuner_simple debug=2 atv_input=2 dtv_input=2
install tuner modprobe -i tuner debug=1
install saa7134 modprobe -i saa7134 disable_ir=1 alsa=1 video_debug=1 install tveeprom modprobe -i tveeprom debug=1

I unloaded and reloaded modules. When I do this, both tvtime shows no signal and 'mplayer tv://' give 'static'. This seems to indicate that the analog path is configured, but the tuner is not working. After I run 'mplayer dvb://', the 'mplayer tv://' just displays a black image. [the applications are functioning with the 2.6.24 kernel].

Reading about this card, I would expect the tda9887 module to be loaded. It seems that loading this module re-activates the static in 'mplayer tv://'. I don't see any reference to the tda9887 when I load the saa7134 (in debug, in /sys/module, or with lsmod). Either that or something like "tuner-simple 1-0061: using tuner params #1 (analog)" in the dmesg output. However, the KWorld ATSC 110 has the 'has_tda9887' set. Is there some problem with my config?

Thanks for any info. Search engines are sparse with information on tuner_simple parameter information. Although I expect I need some code that does ioctls to the tuner modules.

I change my 2.6.27.7 kernel to use modules for the saa7134. On advice from others I used the /etc/modprobe.d and created a v4l.local file,
install tuner_simple modprobe -i tuner_simple debug=2 atv_input=2 dtv_input=2
install tuner modprobe -i tuner debug=1
install saa7134 modprobe -i saa7134 disable_ir=1 alsa=1 video_debug=1 install tveeprom modprobe -i tveeprom debug=1
I unloaded and reloaded modules. When I do this, both tvtime shows no signal and 'mplayer tv://' give 'static'. This seems to indicate that the analog path is configured, but the tuner is not working. After I run 'mplayer dvb://', the 'mplayer tv://' just displays a black image. [the applications are functioning with the 2.6.24 kernel].
Reading about this card, I would expect the tda9887 module to be loaded. It seems that loading this module re-activates the static in 'mplayer tv://'. I don't see any reference to the tda9887 when I load the saa7134 (in debug, in /sys/module, or with lsmod). Either that or something like "tuner-simple 1-0061: using tuner params #1 (analog)" in the dmesg output. However, the KWorld ATSC 110 has the 'has_tda9887' set. Is there some problem with my config?

I use tvtime and mplayer to view ATSC and NTSC content OTA. I have the same input for both and prefer not to split it due to loss. Anyways, with 2.6.24 series and below the drivers seems to pick the inputs 'properly' for my needs. Now they don't. I looked through the source and it seems that things are being structured more sanely.
I have the following output when I set debug=1 for tuner_simple and run 'mplayer dvb://',

I don't get any output when running either tvtime or 'mplayer tv://'. Is there some userspace ioctl call that should be made to set the antenna input for NTSC content? I also tried setting the atv_input and dtv_input values. This didn't seem to change anything.
I started getting lost in the code. Why does simple_std_setup() check for V4L2_STD_ATSC and then unconditionally use atv_input? Maybe that simple_set_rf_input() is undone at a later time?
Thanks for any info. Search engines are sparse with information on tuner_simple parameter information. Although I expect I need some code that does ioctls to the tuner modules.

V4L support for the KWorld ATSC120 is limited. There a numerous threads here which talk about the problems and some work arounds. The developers have talked about adding support but consider new features at the cost of an overhaul of the current driver.

Right now I believe you can not use both ATSC and NTSC tuners w/o power cycling your computer and bringing it up with (only) the appropriate driver. Also, I don't believe the IR receiver works under V4L. This card replaced the Kworld 110 and Kworld 115 tuners. If you can find these older Kworld ATSC tuners, I would buy them instead as I believe they are better supported under V4L (I also have a Kworld ATSC110 - but only use it for ATSC tuning as well).

Go here and read up on how people are setting this card up:

I'm using the Kworld 120 as an ATSC tuner and nothing else in a Debian mythtv slave back end system.
