Parental Rating Labels

Continuing the discussion from MR #1871, I created this thread to avoid polluting the MR discussion. @DeltaMikeCharlie

In summary, Greece OTA EPG contains parental_rating_descriptors for both gbr and gre and because gbr appears first, TVH is (by current design) ignoring the gre rating codes.

As a quick fix, in a private branch, I have changed TVH so that it saves all rating labels, but still uses the first. This was done due to upcoming travel commitments. In order to use subsequent rating labels, the rating labels for the first country need to be disabled and the EPG grabber rerun.

This can only be a short term hack because applying this at a system-wide level will mean that systems that genuinely receive rating labels from multiple countries will be forced into selecting one.

A long term solution requires much more thought and analysis.

I have analysed some Greek and Cypriot mux dumps provided with the following findings:

Country	Raw_Age	Display_Age	Display_Label	Raw_Label	Authority	Icon

Greece

GRE	0	0		K		K		NCRTV		ncrtv-k.png
GRE	5	8		8		8		NCRTV		ncrtv-8.png
GRE	9	12		12		12		NCRTV		ncrtv-12.png
GRE	13	16		16		16		NCRTV		ncrtv-16.png
GRE	15	18		18		18		NCRTV		ncrtv-18.png

Cyprus

CYP	1	4		4		4		CRTA		crta-4.png
CYP	9	12		12		12		CRTA		crta-12.png
CYP	12	14		15		15		CRTA		crta-15.png
CYP	15	18		18		18		CRTA		crta-18.png

Cypriot data also contained country code '902' which is a DVB country group designating 'All Countries'.

For a more complete solution, my first thought was to add a user-defined 'priority' field to the existing rating labels, when multiple labels are broadcast, TVH will use the one which the user has allocated the highest priority. However, this would be system wide and not allow a user to select the rating label of their preferred country when receiving multiple services from multiple countries. It would also not accommodate parental ratings sourced from XMLTV.

I am now favouring adding a 'parental rating priority list' to each service as well as the 'EPG grabber channel'. It will contain a comma separated list of countries/authorities. The first item will have the highest priority and so on.

As previously stated, I have upcoming travel commitments. Consequently, I will not be able to work on this until October 2025.

gbr and gre are the systems provided by the greek private channels. Greek state owned channels seem to only have 902. I have the EPG language set to Greek so one would expect TVHeadend to automatically choose gre.

A reasonable assumption, however, the EPG's parental rating is associated with a country, not a language.

If you were in Cyprus and your language was set to Greek, but you received both Greek and Cypriot parental ratings in your EPG, you would want to see the Cypriot parental ratings, not the Greek ones. Expand that example to a language like Arabic where there are 20+ countries that use that language and hopefully the issue becomes clear.

I see, another option would be to return multiple rating systems when available instead of just one. The API of the provider on the web does that.
