when configuring my atsc usb tuner I got to this point


all modules are loaded and dmesg shows no errors.


Is there a way I can map manually ATSC channels? can you add native support for this? dreambox can play natively the TS and the usb hardware does the demodulation so, it should work.

thanks

Hi elchubi,
I think there is no default frequency table for ATSC in current OpenPli images. Probably there is very little demand for this standard.

Anyway, making it work should not be too difficult. All you need is a terrestrial.xml file with a list of all the possible frequencies used in your country.
For ATSC, the relevant parameters are frequency, bandwidth and modulation type (often called also "constellation").
See the file /etc/tuxbox/terrestrial.xml for examples (for the DVB-T and DVB-C standards).

If I remember correctly, ATSC bandwidth is always 6 MHz and modulation type is always 8-VSB for terrestrial and QAM256 for cable. Anyway, I think you can just set this parameters to "auto". So in the end you just need a list of frequency for your country.

thanks for your attention

I thought about terrestrial.xml, I even edit mine, problem is the list is not being picked up by enigma and it keeps showing "nothing". At parenthesis you can see how it is recognized as ATSC instead of DVB-T, I haven't looked at enigma sourcecode but it might be because of that that it doesn't read terrestrial.xml.

In another linux box with w_scan (would you please add as well dvb-apps from v4l? dvbsnoop works only for dvb) I got this frequencies

The support for ATSC should be already enabled in new images:

http://openpli.git.s...90c883ee149b514

Lurking in the code, I see a reference to an "atsc.xml" file. Try to rename the terrestrial.xml file in this way.
But the code may be still incomplete:

http://openpli.git.s...c34756b1f4fc641

[elchubi]

you are right, it is incomplete

[littlesat]

I suggest we need help here from someone who lives in the USA to get it complete.... As we have DVB-T here so we are not able to debug/test from here.

[elchubi]

I can give access to my box to someone willing to do so.

In the meantime, would you please include "dvb-apps" to the repository? I want to be sure usb tuner is working fine at dm800/openpli-2.1; I have used that tool with a pc/debian to test it.

What can I do to help? Has any progress been made with "atsc.xml"?
 

I have a WinTV-HVR 850 usb device for atsc. My main receiver is a Vu+ Duo2. When this atsc device is plugged into the Duo2, it is not recognized by the current OpenPLi image. 

Any help in this area would be appreciated.  Thanks. EB

good friends i know this an old tread i would like to know how did you get your atsc tuner setup to get it to show under nims?

 

I also have WIN-TV hvr 950q  with all the drivers loaded and i can also use the dvb-apps and tstools from debian mipsel to scan and display channels to an external machine.

 

i used usbtunerhelper file that was written by one of the great people that has the atsc detection built in and was able to compile it so it will run on my mips azboxme.

 

the problem that i run into is that the vtuner0 relate itself to frontend0 rather than frontend1 were frontend0 is the internal dvbs2 tuner.

 

so any help would be appreciated 

[sundtek]

To follow up here we are going to add support for our ATSC devices as well, the first units have been shipped to US already.

 

http://support.sundt...pic,1796.0.html

 

The guys at legitfta.com are testing it with various settopboxes.

[sundtek]

For Settopboxes we dynamically rewrite the ATSC stream tables to report as native DVB-T:

 

 

 

 

 

it is work in progress but it already works. We only used this image because it was pre-installed, however the OpenPLI Image is better of course.

[athoik]

Hi,

I have enabled additional support for ATSC tuners.

Here is the patch https://github.com/a...b2b35abf95a1e6e

Anyone to test?

[athoik]

...coming soon...

[pop_eye]

Good work @athoik, finally someone picked up the slack.

[el bandido]

ATSC is now working in OpenPLi images using the Hauppauge 850 usb device. Special Thanks to Athoik, OpenPLi, and others that made this possible!

The only problems I see are the satfinder does not show a signal strength and there is no astc.xml file located in etc/tuxbox. I have attached an updated atsc.xml and hope it can be added to the image. Channels may be scanned and they play fine Thanks again for all the work! EB

I see a small bar for the signal strength... It would br nice to know the values the tuner gives so we can rescale them.

I have it ready on SatDreamGr, I will commit this later.
