can a station have an hd-1 and 3 with no 2

WJBR was utilizing an HD-1 for their main signal, and HD-2 for radio disney and an HD-3 for the spanish format they also have on W245CJ 96.9. I noticed that the disney format on WJBR HD-2 was the same as WXTU HD-2, which meant overlap. In the past month, if you tune in WJBR you receive the HD-1 then it flips over to the HD-3, there is no HD-2, not an HD-2 with no audio, no HD-2 at all. On my Grundig digital readout it reads HD-1 and HD-3, it skips right to the HD-3 from the HD-1, this also was apparent in my car and with my small Insignia HD radio, so I know its not my Grundig. This happened probably because of the disney overlap with the same programming.
 
What TV channel would that be, also, what you are saying is, a radio station can have an HD-2 and HD-3, but the main signal doesn't have to be in HD, that is really something.
 
Is there any HD-3 signal at all, or an HD-3 signal with dead air. This station has no HD-2, it skips from HD-1 to HD-3. I don't know if its because WXTU HD-3 is Disney and they did not want overlap and looking for another format to put on it, or just some technical problems lasting over a month.

It skips over it.
 
Noticed the same in my car, it skips from HD1 to HD3, hopefully they read my thread about the AWFUL sound quality the HD2 had and are doing something to fix it.
 
As of today, Disney is back on WJBR-HD-2, its the exact same feed as WXTU-HD-3, only thing is there is no readout, it just reads top 40. WXTU has song, title, artist, channel and album art. I would think WJBR's audio should sound better, being its on an HD-2, I don't think HD-3 can carry stereo. I found this out when listening to WIP-HD-3 (WYSP) there is no stereo, its all in mono, have to give it a good listen.

HD 3 can carry stereo.

Essentially, there is one single digital steam. It can be used solely for the HD version of the analog format, or can be subdivided into two or more channels.

Since there is a single stream with a finite bandwidth, if you add HD-2 the bandwidth comes from the HD-1 channel. Each station can determine how to allocate the bandwidth. Each channel can be mono, stereo or even just data.

Think of it as if, for example, the bandwidth allowed for one 320 kbs service on a single channel. Splitting into HD-1 and HD-2, you might leave 256 kbs for the HD-1 and allocate 64 kbs for the HD 3. Or you might cut the HD-1 to less and give the HD-2 96 kbs. If you add a third HD channel, you would similarly reallocate the total bandwidth according to your facility's needs. (I uses the bitrates here as an example, using conventional MP3 metrics to illustrate.

I thought the HD1 had to be 48kbps, with the other 48 for the HD2 and anything else.

If I remember correctly, Ibiquity specifies/requires 48KBPS for the HD1 in their contract.
I'm currently splitting the data for 3 HD channels 32/32/32. Not sure if its legal but all HD channels sound reasonably decent. The Ibiquity cops have not been knocking at my door as they do the moment analog to digital sync slips a sample or two.
