streaming isdb-t setup.

leandro roggerone

Hi guys , im trying to set my tvh server to stream isdb-t signal over my lan network.
This is what I have:
tvh 4.2.7 daemon running on centos7 server.

tbs6814 pci board (drivers installed).

This what I did:
1
add new network:
name: TDA
type: ISDB-T
Pre-defined muxes:Ar-Argentina

save(This automatically adds 55 muxes.)

2
Under TV adapters , I can choose between 4 adapters related to my tbs6814 (dont know why there are 4).

click (tryed on all devices), set enable, set my TDA network and save.

This is the result:

At the muxes section I can see is showing FAIL for all the frequencies.

Questions:
Is my preceadure ok? There are so many checks and options ... perhaps there is something missing.
Is there any tutorial / documentation to follow ? (I can not find it on tvh docs).

Is there some whay to see the received signal level?

Regards,

Leandro.

Under TV adapters , I can choose between 4 adapters related to my tbs6814 (dont know why there are 4).

Because card have 4 tuners ;)

Are you shure that this predefined frequency's are available in your area?

Dear Saen , thanks for your response:
"Are you shure that this predefined frequency's are available in your area?"
Im not sure , im just using the muxes that apeared by defautl.
Im trying to find this data.

Anyway ... is there any way to perform a full frequency scan? similar than tv does when looking for channels.

In canse I get the frequency details:

Should I create a mux for each channel ? Should I do it on the web interface or adding to text file ?

Regards,
Leandro.

You can do that in terminal with


w_scan -f a -x

at final of scan you will see frequency table.

/you need to disable adapter or stop tvh service to work/

compare your frequencys with this one

Dear saen , thanks for your response;
Here are my results,
installed w_scan , and exec as you mention and othere alternatives.
I installed drivers according to tbs documentation and stoped the tvh service but scan result can not be done, this is the result:

I do can see the adapters at tvh gui, like attached image.

Regarding the channel list you provided.

How can I load this list to try ?

#########

Last; is there some way to measure the signal level at the adpater input?

Thanks for your support.
Im trying to reach tbs support as well but have not luck yet.

That also makes me think , drivers are ok ....
I have the feeling it is a rf reception related issue.

Read command from my post then be more careful what ask from w-scan.

Be more critical to your knowledge.

Your command not work and there is no logic to work

You use ISDB-T, but you set frontend to DVB-T

Dear Saen:
Regarding:
"You use ISDB-T, but you set frontend to DVB-T"
I never tweak this parameter and at tvheadend gui it seems to be ok.
this is how it is listed:

Turbosight TBS 6814 (Quad ISDB-T) #0 : ISDB-T #0

It is not same situation mentioned on the link you provided.(RE: TBS6814 ISDB-T Unable to link TV Adapter to Network)

So .. where you see im using DVB-T front end ?

Sorry about this , im newby working with video cards.

Executing:
w_scan -f a -x
also yelds:

main:3886: FATAL:*** NO USEABLE TERRESTRIAL CARD FOUND.***.

Thanks for the support.

Leo.
