Tvheadend

The reason a particular standard is not supported is most likely a combination of factors. Access to hardware/network using the technology and developer interest in the feature is probably the biggest reason for lack of implementation. (This can be likened to Tvheadend's lack of support for CableCARD tuners without workarounds.)

I think this particular instance falls under the "if you want this feature you must implement it yourself" category.

Support is in "Chinese hands"

Honestly, yesterday coming back from work I thought it but have a lack of knowledge about everything involved with the standard itself and the coding. Also there is no other way for me. I would be VERY pleased if you give me some tips to get started. For instance: programming language, required hardware (if you know about it), some related plugins and last but not least how to integrate this future "thing" with Tvheadend. Anyway thanks a lot for your reply. I had to come here to get an answer because nobody even in stackexchange platforms could get an answer. It's funny how cuban government "adopts" this standard only because China is gifting the government the old equipment. Yeah, great "leaders".

@saen_acro Any chinese DTMB support forum?

Because standard is Chinese, https://en.wikipedia.org/wiki/Digital_Terrestrial_Multimedia_Broadcast
Provide more info about frequency used and etc.
There is a support in DVBAPI

Thanks a lot @saen_acro altought this kinda looks very big for me. However this is a reference to someone else. I wiped the web looking for this (not chinese forums) and nothing.

Ohh hold up! The second link you posted looks very promising!

Add new issue for DTMB (and link to this topics)

p.s.
there is a Honk Kong forums in English
if mumudvb or Cesbo Astra work you can use it to fill streams to TVH
But they do not support on-demand tunning
Chinese have patched VDR and MithTV
there is some Chinese Distro's with English UI.
NFVDR http://bbs.nfvdr.com
OPENPCTV https://sourceforge.net/projects/openpctv/
YaVDR http://www.yavdr.org

Issued on https://tvheadend.org/issues/4717 @saen_acro. Hope some developer looks into it. Doesn't seems to be a bad idea after all. Would spread Tvheadend across the entire China, Hong Kong, Macau, Cuba, ...
More users, more support and maybe more developers.

Support added just build last version from GIT
howto manual

p.s.
As I read DTMB terrestrial standard have some of specs DVB-T2 for signal coding
https://www.semanticscholar.org/paper/Analysis-and-Performance-Comparison-of-DVB-T-and-D-Liu-Crussière/16ee852f1e5e6c825703e216ce7ee14431e788cf

Wait a second, have you just added the DTMB support some minutes ago?? I'm asking because I am a sysad interested on Tvheadend but have a lack of knowledge about signal proccesing. I guess you are telling my DVB-T2 have some similar specs with DMTB so basically you modified DVB-T2 support for DTMB. Am I right? Oh boy you rock!!

Not exactly just both standard have some similar parameters for IN-AIR coding

hardware is interested by this standards
software need to tell to hardware parameters for tunning
then hardware send full MPEGTS to software /in some hardware just channel pids/
and then pids are (re)muxed to channel streams with player plays

not so simple as this explaining but nearly

Test and share results.

@saen_acro The topic is getting a very welcome attention (Mark Clarkstone, Jaroslav Kysela and you) on https://tvheadend.org/issues/4717. I'm kinda happy

I'm willing to build .DEB using this link http://tvheadend.org/boards/4/topics/24116 provided by you and test this new feature in Cuba but as I said my knowledge about signals is very poor. So I'd like to know required hardware for testing besides computer (TV streaming server) and networking devices to share the captured video. Government is selling 'litle boxes' for this but this is a builtin system we have no store for this kind of hardware. Basically we have no store at all for engineering purposes. You could suggest me the required hardware or alike and I'll try to somehow get it from abroad.

Hey man thanks for helping me out

In order for you to test/use tvheadend with DTMB you need a device supported by Linux. There's a somewhat outdated list here.

You won't need to create a deb as it's already been done

"You won't need to create a deb as it's already been done"

Do you mean already DTMB support has been added to Tvheadend's repository? That was fast and unexpected

I'm search from other Open-source software with support DTMB standard
only I found is https://github.com/aospan/libjokertv

Yes, the unstable branch is built on each commit.

Awesome, this is awesome. We cuban people are disconnected from real world and the advance. Changing a software in Cuba would take a lot of time. For years government has blocked internet access to people and look what we have been losing. I have to say now we are getting more access (expensive but what to do). I'm thinking about create an article or maybe a blog to share this info and somehow "pay" this help to you guys by giving some coleagues reference about you.

http://tvheadend.org/projects/tvheadend/wiki/Donate

I don't have access to international credit cards. But If you have any related coworker here in Cuba I could give a donation. Very small but a donation. Maybe some help instead in any way.

PS: I deleted my previous comment because was politically biased and it's not related with this topic directly.

@Pedro Pablo Delgado Martell

I have found article about DTT in Cuba on
http://bohemia.cu/nacionales/2018/01/iniciaran-apagon-parcial-de-television-analogica-este-ano/

My question is, have you found TVHeadEnd working with DTMB and what hardware have you used?

How many transmitters are now transmitting in DTMB across Cuba? And is there somewhere list of all of them?

There is a list of television program transmitting in DTMB: http://dtmb.saoing.com/
And there is a device working well with DTMB: https://www.hkepc.com/forum/viewthread.php?fid=116&tid=2455515&page=1
There is a application about a DTMB device: https://www.cnblogs.com/DirWang/p/17063658.html
