Effective on or after 12/3/2020 we're making Effective on or after 12/3/2020, we're making it
easier to watch the channels you love. We are removing the duplicate HD channels on 1000-1950. You can still enjoy the
programming previously on these channels by tuning into the lower 2 or 3-digit corresponding channel number. What channels will tivo cable card users use to view HD?
that is not the info the channel lineup page.
If your television is connected via equipment other than a mini box, such as a Cox HD receiver or a Cox-provided CableCARD together with a CableCARD compatible retail device (and a Cox-provided Digital Tuning Adaptor for certain channels), programming is available in high definition only at the HD Channel position - typically the four-digit number above 1000.
available in high definition only at the HD Channel position
This is a recent change so Cox probably hasn't updated their web page.
These "positions" are called Virtual Channel numbers and are sometimes remapped. Virtual Channels are what you press on the remote control and not the actually frequency of a transmission.
The "big" networks insist lower Virtual assignments so their programming isn't buried deep within the program guide. I remember when Fox first launched and there was lots of contention for lower channels.
I think providers screwed up back during our transition from analog to digital TV. If Digital TV was to be the future, why didn't the providers originally map (assign) all HD channels to the 2- or 3-digit equivalent and make SD channels 4-digit. "Oh...we didn't want to confuse everyone?" It would have been better to confuse us then rather than now.
Best case: the name of the channel (e.g., WRCDT) doesn't change. In this case TiVo should process it as a channel reassignment. They'll be a big message on your TiVo's identifying all the reassignments. All your One Passes will continue to work. All recordings happen as scheduled.
Not so good case: the name of the channel (e.g., WRCDT) does change (e.g., to WRC) . In this case TiVo should process it as a channel delete and add. They'll be a big message on your TiVo's identifying all the deletes and adds. All your One Passes will need to be updated to reference the new channel name. Some recordings missed if you don't edit the One Pass in time.
Worst case: some channel names change, others don't. Changes happen on different days with new names added on a different day than the old names are deleted. Some recordings missed. Generally a big mess that you'll have to sort out manually.
This is just a remap of Virtual Channels.
TV networks go by lots of names. For example, the name of its national or local affiliation (NBCUniversal), the name of the station (NBC4), the callsign of a station (WRC-TV), UHF or VHF frequency of the station and its provider-assigned Virtual Channel (4).
Cox is responsible to assign the Virtual Channel (4) because they're amassing all these networks onto their cable boxes. If you press "4" on a Cox remote, the Cox cable-box will tune WRC-TV.
The names of affiliations, stations, callsigns and frequencies are not changing...only the Cox-assigned Virtual Channels are changing.
Virtual Channels really depend of the local affiliates within different markets. For example, when I lived in Maine, CBS was Virtual Channel 5. Here's, it's 9.
