[mythtv] Using original network identifiers in the "temporary" range to identify UK DTT multiplexes

[Roger James]

Hi,

After struggling with reconciling table version numbers in the UK DTT 
network, I am having a rethink. The versioning problem arises because the 
UK DTT network uses a single original network identifier. This identifier 
does not identify a group of transmitters carrying the same multiple, but 
the UK network as a virtual whole. However the DTG (the outfit that manages 
UK DTT) dishes out ranges of transport stream IDs and service IDs for 
individual multiplex operators to use. These ranges are defined in this 
document 
http://www.digitaluk.co.uk/__data/assets/pdf_file/0008/87371/UKDTT_DVBID_Allocation_v1_1.pdf. 
It shows that a multiplex identifier can be extracted from these IDs.

I am thinking of mapping this identifier into the "temporary" range (0xFF00 
- 0xFFFF) of original network identifiers and using this replacement 
original network identifier within the dvb facing side of the EIT code. 
Hopefully this will allow me to limit the UK specific part to a very small 
area of the code.

Comments anyone?

Do you think it will work?

If it does not work I will have to revert to my original plan to maintain 
separate version structures, which is a RPITA (or RPITB if you are in US).
