Feature #4463
update predefined mux list for USA
0%
Description
Please pull down the updated pre-defined mux list for the USA/Canada. Neither country currently uses channels 52-69. (frequencies 698Mhz and above)
The list was added to the upstream https://github.com/oliv3r/dtv-scan-tables repo as us-ATSC-center-frequencies-8VSB-062009
This should replace the us-ATSC-center-frequencies-8VSB - but for some reason it was added as an additional pre-defined mux list. It would be better of that were named US-ATSC-2017
Also - as a note - the US will begin moving station frequencies later this year into next year as part of the incentive auction repack. This will happen in phases, but will require most markets to rescan for new services(channels) a few times over the next 3 years. Beginning in 2020, the US will no longer uses channels 37 and above. (frequencies 608Mhz and above)
One could also make a pre-defined mux for US-ATSC-2020 with the smaller list.
The complete list of stations changing channels can be seen here: https://www.rabbitears.info/repackchannels.php

Updated by That only deals with satellite - not with the over the air (ATSC) signals.
And the issues for the USA and Canada is stations will be moving frequencies over the next 3 years in 10 phases. So users will need to rescan when they "lose" a channel.
It just makes sense to update the pre-defined ATSC mux list to the shorter channels 2-51 for now to speed up the scan process.

definitely not informed enough
# US ATSC center frequencies, use if in doubt A 57028615 8VSB A 63028615 8VSB A 69028615 8VSB A 79028615 8VSB A 85028615 8VSB A 177028615 8VSB A 183028615 8VSB A 189028615 8VSB A 195028615 8VSB A 201028615 8VSB A 207028615 8VSB A 213028615 8VSB A 473028615 8VSB A 479028615 8VSB A 485028615 8VSB A 491028615 8VSB A 497028615 8VSB A 503028615 8VSB A 509028615 8VSB A 515028615 8VSB A 521028615 8VSB A 527028615 8VSB A 533028615 8VSB A 539028615 8VSB A 545028615 8VSB A 551028615 8VSB A 557028615 8VSB A 563028615 8VSB A 569028615 8VSB A 575028615 8VSB A 581028615 8VSB A 587028615 8VSB A 593028615 8VSB A 599028615 8VSB A 605028615 8VSB A 611028615 8VSB A 617028615 8VSB A 623028615 8VSB A 629028615 8VSB A 635028615 8VSB A 641028615 8VSB A 647028615 8VSB A 653028615 8VSB A 659028615 8VSB A 665028615 8VSB A 671028615 8VSB A 677028615 8VSB A 683028615 8VSB A 689028615 8VSB A 695028615 8VSB A 701028615 8VSB A 707028615 8VSB A 713028615 8VSB A 719028615 8VSB A 725028615 8VSB A 731028615 8VSB A 737028615 8VSB A 743028615 8VSB A 749028615 8VSB A 755028615 8VSB A 761028615 8VSB A 767028615 8VSB A 773028615 8VSB A 779028615 8VSB A 785028615 8VSB A 791028615 8VSB A 797028615 8VSB A 803028615 8VSB

My point is the following frequencies from that list are no longer in use:
A 701028615 8VSB
A 707028615 8VSB
A 713028615 8VSB
A 719028615 8VSB
A 725028615 8VSB
A 731028615 8VSB
A 737028615 8VSB
A 743028615 8VSB
A 749028615 8VSB
A 755028615 8VSB
A 761028615 8VSB
A 767028615 8VSB
A 773028615 8VSB
A 779028615 8VSB
A 785028615 8VSB
A 791028615 8VSB
A 797028615 8VSB
A 803028615 8VSB
Those have not been used in NOrth American television since 2011 - leaving them in the pre-defined list causes a tuner to waste time scanning frequencies that are not valid. Therefore - let's get the list updated with those removed. :-)
