Need Some Help Tuning Please

[Huevos]

@FatTony, we already know he is receiving from Dover. The problem is that Dover is a repeater of Bluebell Hill, so the DVB tables correspond to Bluebell Hill, because that is what it is repeating.

Can you do a manual complete scan, selecting T2. Then upload the resulting lamedb file.

T2 manual complete scan run. File attached.

Probably because I forgot to paste the link.

I've posted the Dover T2 XML

I think we are a cross purposes or have different interpretations of what a repeater is. Dover is an 80kW transmitter with a number of repeater stations. Bluebell Hill is a separate transmitter (20 kW) with its own group of repeaters. Repeaters normally take the signal from a main station and transpond it on a different frequency to fill-in areas of poor reception. I think you are using the term repeater to cover an instance where the PID/TSID data in the multiplexes is identical to another? In that sense all Saorview transmitters are repeaters according to ABM. I did a bit of a trawl on ukfreetv and found that the PID data (for ITV certainly) is shared across many transmitters in that south east region of England including Heathfield, Hastings, Dover, Bluebell Hill and others (10150). But they all have different UHF channel allocations. Geography is what determines what transmitter you can receive and to a large extent the end-user needs to have his aerial pointed at the correct transmitter (or its relay station) and tune the correct UHF frequency. In an environment where the stream data is not unique the searching algorithm should be frequency first and data content second. TVs and standard STBs don't have PID lists in them and use frequency searching and signal strength/quality to determine which multiplexes to store in the top positions on their channel lists.

In the satellite environment ABM works excellently because there is a single "home" transponder in a unique location in the sky which the dish can see. In the UK, although the principle of a "home" transponder in Freeview still stands, there is the issue of identifying which transmitter it is coming from and that is down to local geography and the end user's knowledge. In Saorview (as you have seen in the other thread) the "home" transponder principle does not hold good at all. I would assume that across Europe the situation would differ from country to country. Nevertheless, you and Peterj have made some great strides with ABM in the terrestrial environment despite the difficulties of transmitter locations and the added complication of DVB-T/T2 in the UK environment.

Tony, call it what you like, repeater, relay, etc, the point I am making is the transmission from that mast is a carbon copy of Bluebell Hill, including the dvb tables.

Can you try with this xml file please? For now, it goes /usr/lib/enigma2/python/Plugins/SystemPlugins/AutoBouquetsMaker/custom/

Would be great if you can also test with no lamedb file in /etc/enigma2/ This ensures a test with no chanenl data on receiver. You must put enigma2 to sleep first with "init 4" command before deleting.

Yes, frequencies are different but data is identical.

Would be nice if we could download the TSID data somewhere.

Deleted the lamedb file, uploaded this XML and ran ABM again . . . I get an HD Bouquet

Please check a few channels on each "channel/frequency" to ensure all is fine before we commit.

It's exactly the point I'm making! If the end-user does not know exactly what frequency he/she is receiving the best signal from and the receiver can see two or more different transmitters/relays, then there is always a risk that ABM will pick up the weaker signal or a DVB-T instead of DVB-T2 (HD) stream. It's almost entirely down to the level of research an end-user goes to in order to find the best transmitter location and select it in the ABM transponder/mux list.

Just flicked through every channel to be on the safe side . . . all good

The scan frequency is set in the XML, so how could it come from the wrong one?

Problem here is Dover is transmitting tables from Bluebell Hill.

Just want to add my thanks for the help received on this thread, you chaps are legends
