Default DW-TV in widescreen

I just noticed that DW-TV (channel 195) is apparently in widescreen SD (16:9 with no black bars). Has it been this way for long?

My 8300HD is set to output only 1080, so if it is a 480 signal, I'm getting it upconverted. I have a 32" HD LCD TV.

Is this an HD channel now, or can SD customers see it? What does it look like on an SD 4:3 TV? Squished or letterboxed?

Can they do this for other SD channels?

Very interesting. This is still a 480i signal (I have it (480i) and passthrough enabled) on my PVR and seems to behave like other SD channels. However, if I change my PVR to 1080i - Fixed - easy to do under the settings and quick settings, then it appears as a widescreen channel. I'm guessing that there must be some sort of signal in the channel that indicates that it's widescreen and the STB is "seeing" this signal. Note that the "format" under the quick settings is not stretched, but still "normal".

Wonder if there are other channels out there like this...

What does it look like when you are receiving it as 480i? Is it letterboxed or 4:3?

I'm noticing the same thing on WTVS on Rogers, a widescreen picture but I think they are carrying the wrong sub-channel of WTVS because the programming doesnt match the Guide Info? It seems to be airing only PBS Kids programming instead of the normal PBS feed

Deutsche Welle switched to 16:9 over the summer; I watch the channel regularly. Rogers isn't doing anything special; the broadcaster is delivering it that way apparently. There's some great stuff on that channel in English, actually. I get it as part of the News Theme Pack (along with MSNBC, FOX, EuroNews, etc).

Normally a WS programme would be "postage stamped" on a 16:9 TV (bars all around). It is when the STB is set to 480i/passthrough.

It's only when the STB is set to 1080i/Fixed, that it's WS, which is "different" from other SD channels that have WS programming, so there must be something unique about the channel which allows for this to happen under that circumstance.

DW is adopting 16:9 broadcasts (4:3 anamorphic):

>>>I'm noticing the same thing on WTVS on Rogers<<<

Yes, channel 163 is displaying in widescreen as well.

>>>but I think they are carrying the wrong sub-channel of WTVS because the programming doesnt match the Guide Info<<<

The logo shows WTVS-DT Detroit 56.2 and does apparently have a lot of kids programming.

You know, i'd call and let them know but I think its just a waste of time trying to explain it. I'm sure they will figure it out sooner or later, and switch feeds.

The MPEG2 header can be flagged with the aspect ratio of the broadcast, and the HD set top boxes listen to that flag. It's the same as DVDs when your TV switches between 4:3 and 16:9 modes as well.

Could this be done on a show-by-show basis in order to get rid of "postage stamp" shows once and for all?

I don't think it is the TV though, the set-top box senses the flag and presents anamorphic 4:3 AR frame in stretched to 16:9 AR 1080i format...

Well let me be a bit more specific. It is this same method that DVDs use to control TV aspect ratio. But in this case the STB is handling the flag and processing it rather than the TV.

At 9:05 PM, Sunday night, channel 163 has a center cut 4:3 of the same program (Wuthering Heights) being shown on PBS-HD. My guess is that the SD version of PBS Detroit is now being created by conversion from the HD signal in preparation for the shutdown of the analog transmitter. The WS version seen previously might have been a setup error in the downconverter that has now been corrected.

DW looks good in 16:9 SD.

BTW, don't assume that SD STBs can react to MPEG aspect ratio flags or pan and scan instructions. It might be in the MPEG chip but not be activated in the box setup software.
