If, like me, you get some of your TV services via a Linux computer using TVHeadend, MythTV or similar, you will possibly need to know a few technical details to get your system to retune after phase 1 of the switchover for the Meridian region. I personally use TVHeadend and these are the details I had to enter:
Frequency (kHz): 666000 Bandwidth: 8 MHz Constellation: QAM-64 Transmission mode: 8k Guard interval: 1/32 Hierarchy: None FEC Hi: 2/3 FEC Lo: 2/3
Whilst adding the details for the MUX that was moved, you might also want to remove the details for the “B” MUX (on 674.2MHz) as the channels located there are now all also on the moved (now called PSB1) MUX.
You may also want this updated uk-Hannington file. I’ve taken the one which on my Ubuntu system was located in /usr/share/dvb/dvb-t and modified it.
# UK, Hannington # T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy # This is the MUX that was moved on February 8th #T 706000000 8MHz 3/4 NONE QAM16 2k 1/32 NONE # Moved MUX T 666000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE T 650167000 8MHz 2/3 NONE QAM64 2k 1/32 NONE T 626167000 8MHz 2/3 NONE QAM64 2k 1/32 NONE # The channels on this MUX are now duplicates of channels also available on the moved MUX #T 674167000 8MHz 3/4 NONE QAM16 2k 1/32 NONE T 658167000 8MHz 3/4 NONE QAM16 2k 1/32 NONE T 634167000 8MHz 3/4 NONE QAM16 2k 1/32 NONE
The details here are only valid from February 8th and until February 22′nd 2012 when a new retune needs to be performed.
