I wonder why they show the LA DMA as 113, when the network ID for it is 624? It is confusing that they include DMA numbers in a list of network IDs, especially when each DMA has its own non-overlapping network ID assigned. I have to agree with P Smith here, this data doesn't look particularly reliable so I wouldn't read much into it.
Did you ever add Portland, OR as a secondary market, perhaps to get a certain local station that isn't picking up through the other two DMAs? That's DMA 150, and may be the source of that network ID 150.
Is there a way to wipe out a receiver's OTA configuration - i.e. remove all the primary/secondary markets, and erase all the channels it has scanned? If you do that, does the 150 stay there?
Please check out the "LIL Market" tab of the TPN Map Excel while you read this -- it will help make sense out of all this...........
Let's use Los Angeles as the example:
All at the same time, Los Angeles is:
DMA # 2 --- this is of value to the marketing folks and advertising people and provides the relative ranking, in size, for this DMA in the Nielsen Domestic DMA universe
Network # 624 --- this is Directv's engineering assignment of a Network Identifier. Note these run from 512 through 724. In an engineering view, the Los Angeles Local-into-Local channels all originate in Network 11 or Network 14 and are Re-Directed to Network 624.
Market # 113 --- this is also a Directv assignment; notice these market numbers are simply assigned in sequence to the alphabetical list of DMAs. Yes, there are a couple of exceptions; but that is yet another long, long story.
So a couple clarifying points:
1. Directv, to the best of my knowledge, never uses the DMA number (ranking) outside of the marketing department.
2. The range of Market Numbers and Network Numbers are clearly distinguishable. Market numbers are 1 to 213, Network numbers are 512 to 724. OR just add 511 to the Market to ge the Network OR just subtract 511 from the Network to get the Market.
3. The HoTat2 display appears to include both Network Numbers and Market Numbers. I don't know the motivation to do that, but that certainly appears to be the case.
