Tvheadend

Can I add a "YES PLEASE" to this request?

tvheadend users in Auckland NZ can be up and running immediately with a 7 day EPG straight out of the box.

Those of us outside Auckland have to fiddle around with XMLTV along with an EPG file which is tricky to nail down. I'm getting close to sticking tvheadend in the "too hard" basket because of it.

I upgraded to 4.1 hoping the "EIT - skip TSID check" option would make things work but it doesn't help. I still get "epggrab: EIT: DVB Grabber - data completion timeout for 578MHz in TVNZ" and "epggrab: EIT: DVB Grabber - data completion timeout for 562MHz in Mediaworks" which are the 2 main networks in NZ.

Some way of specifying what transport stream to pull EIT data off for each MUX would be FABULOUS.

After years of only including now and next EIT information, DVB-T broadcasts in New Zealand now include a full 7 day schedule.

Unfortunately for viewers outside the Auckland region, the 7-day EIT EPG data only shows up in Tvheadend for a few channels. This is because the Auckland 7-day EPG is broadcast nationally, and EPG data for most channels does not map on to the regional multiplex channels, although the programme content is identical to that for the Auckland region.

I think that the reason is this: (quoted from http://www.freeviewnz.tv/media/1055/freeview_dtt_transmission_rules_2_1.pdf )

_
5.12 EIT Schedule actual and other
The DTT Freeview network will not Transmit EIT schedule (actual or other) information. The EPG data will be handled by an MHEG-5 EPG application, however due to the introduction of MHEG enabled PVR devices, the Freeview DVB-T Network now does carry limited CRID data in the EITSchedule actual and other tables.

To limit the EITschedule bandwidth broadcast on each multiplexer, EITschedule_actual and EITschedule_other tables are activated on Transport_streams;-
0x19 TVNZ Auckland multiplexer,
0x1d TVWorks multiplexer
0x21 Kordia multiplexer.

The TVNZ regional multiplexers transport_stream_ids 0x1a, 0x1b and 0x1c are deemed identical to transport_stream_id 0x19 since they are made up from exactly the same service_ids, event_ids and associated CID data, differing in advertorial content only. EITschedule_actual data is not activated on these multiplexers.
For a PVR device to fully populate its event information database with every Freeview services event_ids, irrespective of its current active multiplexer it must parse both the EITschedule actual and other tables. If the database includes duplicate service_ids irrespective of their transport_stream_ids it shall discard the service_id with the lesser signal quality.

_

Is there any way to make the broadcast EIT data map correctly on to the regional multiplex broadcasts?

Could you (just for a test) do this change:

And activate the 'VIASAT: Baltic' EPG grabber ? Do you see any extra EPG data from '0x19 TVNZ Auckland multiplexer' ?

Hi Jaroslav,

Thanks for looking at this! I currently have TVH running on a Synology NAS, so I'll give your patch a try, but it may be a few days before I get everything set up to compile and run TVH on my desktop.

I asked for MHEG-5 EPG support a while back got accepted as Feature #3783. I'm in the Wairarapa wonder if this would work for me two as I am using the XMLTV script, it works but it can be frustrating

If I've understood other people's postings correctly, Freeview in NZ started out with the full 7 day EPG only being broadcast in MHEG-5 format, while the EIT guide was limited to Now and Next info. It was and is possible (but quite fiddly!) to extract the MHEG5 EPG data to an XMLTV file using https://sourceforge.net/projects/mheg2xmltv/

The MHEG-5 EPG is still being broadcast, but at some time in the past year or so, Freeview quietly started broadcasting the full 7 day EPG in EIT form as well. Unfortunately, they're doing it in a slightly non-standard way, which TVHeadend doesn't currently cope with (I get a full 7 day EIT EPG in Wellington for some channels such as Maori TV, but not for the TVNZ and Mediaworks channels). Other software such as NextPVR and MythTV have apparently been able to make changes so that users throughout New Zealand receive the full EIT EPG.

More info here:
http://www.geekzone.co.nz/forums.asp?forumid=126&topicid=205124

If it's possible to get the working in TVHeadend, then yes, it should be possible for users anywhere in New Zealand to get the full EPG using only the built-in EIT grabbers.

My next couple of weeks are looking very busy, so if anyone else has time to try compiling with Jaroslav's patch above, that would be wonderful!

I think what also would be really helpful here is a mux dump. This would allow Jarosav to confirm his patch is working if needed.

If either of you want to upload one, you can do so here: http://pam.exsilia.net/issues/4198 (avoiding cloudflare's 100Mb limit).

just wget a mux url & upload the resulting ts file

I was going to offer to run something (specified by someone with more knowledge than me) in dvbsnoop and send the output, but a mux dump is more useful?

I was running the Debian package as provided in the repository but downloaded the git source. Made the change and compiled it and it ran (so far so good) but isn't picking up the EIT EPG. I'm having trouble with the EPG from the other muxes so I've probably screwed up somewhere else anyway.

Also, the spec for EIT appears to have been updated...

http://www.freeviewnz.tv/media/1216/freeview_dtt_transmission_rules_3.pdf

"Updated rules around EIT schedule population within the FreeviewNZ DVB-SI. All changes from version 2.4 have been highlighted in pink."

Also:"Strings shall be compressed using sets of static Huffman trees defined by FreeviewNZ. FreeviewNZ will use two lookup tables. Each will be a maximum of 10kilobytes in size. These tables are available electronically from FreeviewNZ."

That newer spec also has changes to the list of transport stream that carry full EIT data:

####
To limit the EITschedule bandwidth broadcast on each multiplexer, EITschedule_actual
and EITschedule_other tables are activated on Transport_streams;-
0x19 TVNZ Auckland multiplexer,
0x1d TVWorks multiplexer
0x21 Kordia1 multiplexer
0x22 Kordia2 multiplexer
0x26 Hawke’s Bay TV Multiplexer ####

The 0x21 and 0x22 TS's are available on the transmitter here in CHCH.

Sorry about rabbiting on.

In my case (Christchurch transmitter but applicable to entire South Island), epggrab needs to pull the EIT from the mux with TSID 0x21, and map anything listed as TSID 0x1d to 0x20 and TSID 0x19 to 0x1c

That's correct?

Is that easily done?

Part way there.

The EPG coming off EIT was very sparse for the channels on that actual feed.

I changed the grabber we were experimenting with from viasat_baltic to uk_freeview and have got much better results. I'm guessing this is because of the Huffman encoding on the EIT data.

I added the pid line:

if (!strcmp(m->id, "uk_freeview")) {
   pid= 0x22;
    m = (epggrab_module_ota_t*)epggrab_module_find_by_id("eit");

and now the EPG has all the info for the channels that are on the "normal" transport streams.

We just need to be able to map EIT data from those TSID's listed above and we're good to go.

Maybe a epggrab module for each NZ region will be required?

Here's a list of my suggestions for their names (based on the formal document) and the TSID's that need to be mapped:

nz_freeview_auckland (no mapping required)
nz_freeview_central 0x0019 -> 0x001a , 0x001d -> 0x001e
nz_freeview_wellington 0x0019 -> 0x001b , 0x001d -> 0x001f
nz_freeview_south_island 0x0019 -> 0x001c , 0x001d -> 0x0020

Where do I find the TSID's. I'm in the wairarapa so I want to check that I have the same as Wellington??

Thanks

Go to Config -> DVB Inputs -> Muxes and the TSID should show in column #6

If you take a look at http://www.freeviewnz.tv/media/1216/freeview_dtt_transmission_rules_3.pdf (18.1.7 Cell_id) it shows a Manawatu TX at Popoiti, which is southwest of Carterton? That shows the same TSID's as Wellington.

I've struck a problem with using uk_freeview as the EIT grabber - all my recordings are set to UTC rather than our current UTC+13, so I'm getting the wrong programmes recorded. :^(

You can change the time offset in the network settings - 'EIT time offset' field.

Could you try the above patch? It was applied to v4.1-2460-g003bebf . If I understand correctly, the 'Auckland' grabbler must be enabled and then you should enable the regional grabber which has the higher priority (thus events from these grabbers will override events from 'Auckland').

Hi Jaroslav,

I tried it, but I think it's missing the code to treat all those NZ EIT feeds the same as the UK_Freeview ones - they need the Huffman tables applied?

I think the bit missing is:

if (!strcmp(m->id, "uk_freeview")) {
    m = (epggrab_module_ota_t*)epggrab_module_find_by_id("eit");
    if (m->enabled) return -1;
  }

???

Thanks,

I've got it set to "Local (server) time". It appears to be ignoring that and running on UTC.

UTC+12 and UTC+13 don't appear as options.

I've created a PR that adds a note about the NZ grabbers to the help docs, and added UTC+12 & +13 to the offset list. If you want to manually add them in (instead of waiting for the PR to be merged) you can see how by looking at my PR here.

Getting loads of entries in the EPS with blank Title, which indicates the huffman issue isn't resolved as yet, unfortunately.

Could you check the value of (intptr_t)m->opaque variable in _eit_get_string_with_len() function ?

The TSID's I have off Popoiti are 27 (0x001B) 31 (0x001F) 33 (0x0021) & 34 (0x0022), so which one is transmitting the guide?

Same as Wellington, then.

Full 7 day guide should be on 33 and 34.

Is that what you are after?

Full log, please, start with lines when you subscribe to a channel on a mux with incomplete EPG, wait for 60 seconds and attach (upload) this log to this bug.

subscribe to a channel on a mux with incomplete EPG

Not sure what you mean by that. Do I enable a channel in the DVB Inputs -> Services tab?

While you have debugging going, play a service that is missing EPG data.

Ah! I understand now.

There's just one grabber for NZ now - it enables the huffman decoding and specifies priority for the local EIT info. Both EIT and NZ Freesat may/should be enabled.

I reverted other changes, because the design was wrong (I worked with MPEG-TS PID not TSID - blame me ;-().

I don't think we're quite there yet.

Nothing is appearing in the EPG. I have modules OTA EIT DVBGrabber and OTA NZ Freesat enable.

Also, I think the module should be called NZ_Freeview rather than Freesat.

Thanks!

Traces ? I renamed nz_freesat to nz_freeview in v4.1-2477-g019c946 .

Hang on, I see eit.c has been changed. I'll run another trace and report back.

OK. I get it. The problem is, for us old folks in NZ these used to be all separate networks so when we set stuff up from scratch we fail to realise that technically they're just one network now.

So I deleted all but one network, and loaded the predefined MUXes for Christchurch. That must be old data because they are on different frequencies now.

When I manually changed one to 594MHz everything was fine, but when I changed the 2nd one to 578MHz, I had a crash...

If I try to have the MUXes located automatically they are not found.

If I load the predefined CHCH muxes I have to change the frequencies. They should be 530/562/578/594MHz.

When I change the frequencies for Kordia1 and Kordia2 MUXes (530 & 594MHz), everything is fine and dandy - the 7 day EPG populates and it's perfect.

When I change the frequency for the TVNZ or MediaWorks Muxes, and initiate a scan, I get the crash.

The stuff in the trace log before the crash is:

Yo should delete the directory "tvheadend" and then clone again. Finally, inside the folder "tvheadend" do ./Autobuild.sh

Could you a bit comment SID numbers (you can find the SID - service ID - numbers in the services grid) for the last EPG log? I need to know which SID numbers (services) are without0 EPG data or incomplete data. You can easily verify, if there are EIT entries in log for these SID numbers:

That program actually runs from 7am to 10am local time.

It looks like time(zone) issue again. Check, if your server settings has really correct time and timezone and try to return back the 'timezone' settings for tvh network to 'local time'.

  (7-13)+24 = 18 : start=2017-03-22;18:00:00(+1300)

Before switching over to the dev version of tvheadend I had no problems with timezone.

The dev version allows to override the timezone but keeps the local time / UTC time functionaly. Here's the diff between 4.0 and 4.1 latest code:

-dvb_convert_date(const uint8_t *dvb_buf, int local)
+dvb_convert_date(const uint8_t *dvb_buf, int tmzone)
 {
   int i;
   int year, month, day, hour, min, sec;
@@ -433,7 +566,50 @@
   dvb_time.tm_isdst = -1;
   dvb_time.tm_wday = 0;
   dvb_time.tm_yday = 0;
-  return local ? mktime(&dvb_time) : timegm(&dvb_time);
+
+  if (tmzone == 0) /* UTC */
+    return timegm(&dvb_time);
+  if (tmzone == 1) /* Local time */
+    return mktime(&dvb_time);
+
+  /* apply offset */
+  return timegm(&dvb_time) - tmzone * 60;
+}

Enum table:

static struct strtab dvb_timezone_strtab[] = {
  { N_("UTC"),        0 },
  { N_("Local (server) time"), 1 },
....

Just try to return the time configuration back as in 4.0.

OK. Here's the current status of the NZ Freeview EIT grabber module when run in CHCH.

If enabled only on the 562MHz (Mediaworks) mux, nothing happens
If enabled only on the 578MHz (TVNZ) mux, nothing happens
If enabled only on the 594MHz (Kordia) mux, the full EPG data for only the 594MHz Kordia mux is successfully grabbed
If enabled only on the 530MHz (WorldTV) mux, the full EPG data for only the 594MHz Kordia mux is successfully grabbed

As stated previous, the EPG data for all 4 muxes should be showing up on both the Kordia and WorldTV muxes.

Suggestions please?

Trace logs with the description?

The trace lines shows SID and TSID numbers. If you see 'svc=' line, then the EIT event is decoded and should be pushed to the database (unless the time is in past or something else is wrong). If you don't see 'svc=' line, then something is wrong and I need to know also TSID of the tuned mux (see mux grid).

Also note that tables 4E and 4F (tableid=) are for present/following events only. The full EPG info is in tables 5X and 6X.

I would start with 562Mhz, because it does not work. Watch one service (channel) from this mux when TVH is idle (no scan or EPG grab is running) and attach the logs between 'subscribe' and 'unsubscribe' operation. Give me TSID of 562Mhz mux, and describe one or more SID numbers which you see in the log but they are without EPG events.

TvHeadend 4.2.2 has now appeared in LibreElec. I see the New Zealand grabber option but for me it didn't seem to do work at all. Is there something I can do to help contribute to this?

I get only now/next for TVNZ and Mediaworks channels. The EPGs for all other channels populate correctly.

I am in Wellington.

I have enabled:
- Over-the-air: EIT: DVB Grabber
- Over-the air: New Zealand: Freeview Base
- Over-the-air: New Zealand: Freeview Local

Has anybody in Wellington or regions other than Auckland got the EPGs working?

If so, are there configuration settings I have overlooked?

Thanks in anticipation.

I'd like to please add my wholehearted support for ensuring robust and reliable support for New Zealand terrestrial EPG. I'm in Auckland and the EPG works to the degree that all channels display full EPG date/time slots for a week or so, but the descriptive elements are sometimes displayed and sometimes not - mostly not.

Seconding the request.

I'm in Auckland and no combination of Freeview Base/Freeview Local results in useful EPG data for me.

The "New Zealand: Freeview" grabber in 4.2 stable worked perfectly for me, so I'm stuck using this very old version.

I can't help with the fundamental code issue here, but have an alternative solution that's working with the mheg-5 data that is broadcast.
