I wonder why they went with such an odd PSIP designations? 22.2 & 22.6? I wonder if this is just first draft tuning to get them online by the May 1st date.

I would bet that 22-2 and 22-6 are not the permanent sub-channels. My guess is the engineer is getting familiar with the encoder.


Are you guys getting sound on 22-2? My Sony HD-200 isn't decoding the audio. My Onkyo receiver has the Dolby Digital 3.2 indicator lit.


I looked at the PBS HD feed on 22-6 and really could not pick up any degredation after the SD channel was added. There was a waterfall scene in the NJN footage that turned into a pixeled mess but I don't know if it was that way before.


I think WMPB is due to come up on May 1st on Digital Channel 29 isn't it?

I get no audio for 22.2 either. Wmpb is questionable for May 1. I do know that Wfpt was supposed to be on May 1st but is pushed back until late Fall. I would not be surprised if Wmpt is the only digital station they have on for a while. Jeff

antennaweb.org now has WFPT has Sep 2003, and the other MPTs as June.


Its funny that WMPT-DT annapolis isn't even listed on Antenna web. The analog is.


On other News, WHUT-DT is listed as May 1st and Univision is listed as May 15th. I don't regularly watch either channel, but If HUT has a HD loop well that will be better than nothing.

I tried to get Smart Travels at 7:30 pm. I tried all the subchannels on 22, 42 and 80. On 42.6, I got Smart Travels only as NTSC (from composite not component outputs).


Did anyone get HD on WMPT last night? Have they starting doing their HD broadcasts after 8 pm, like WETA?

MPT sent me an email and said that their Frederick MPT station would not be Digital until late fall. Sorry.

I succeeded in getting WMPT HD on 42.6, which switches to 22.6, but only by using my other set top box, the old Panasonic DST-50. My RCA DTC-100 is not capable of receiving it, even though WETA-HD comes in fine. Signal strength is good for both stations.


There is clearly been a deterioration in PQ on WMPT-HD though ... almost as bad as WETA-HD.

Hopefully the problems I'm seeing are just because MPT is still in transition, but I haven't seen anyone else mention the same symptoms, so here they are...


22.6 is fine, no problems.


22.2 I get picture & sound immediately. Picture freezes after about 5 seconds, sound continues. Sometimes picture will refresh every 5 seconds or so, while the sound continues normally. Other times, my STB will just go to a "No Signal" state, even though there is a strong signal as indicated by 26.6. The STB is a Samsung SIR-T150.


Anyone else with similar problems? I got to believe at is an encoding problem, but it sure is taking a while to get corrected. Seems like its been a week or 2 now.

jswclw,


Same here. A check today revealed that 22.2 is just as you describe - no picture for a while, and then periodic frame updates every 5 seconds or so. Strange, since it was fine last week. I have a SIR-T150 as well.


I still can't decide whether the picture quality on 22.6 is lower than it used to be before WMPT-DT started multicasting. It might be a little worse, but if it is, it's pretty minimal.

Thanks for the responses...


I have been seeing this problem off and on ever since WMPT started multi-casting. I'm surprised its taking them so long to get it squared away. When its working, I like the option of watching the HD feed or the local MPT programming.

22.2 and 22.6 both are functioning properly now.

Well 22.2 certainly doesn't look very good at all, picture-quality-wise. On the other hand, 22.6 still looks quite nice. So maybe you're right, even though there's obviously not much bandwidth to sacrifice to start with on a 480i feed. If you're watching 22.2 anyway, it's for content rather than picture quality, so if that's what they're doing, it's the right choice.

I still wonder about the odd sub channel number assignments. 22..2 and 22.6? I wonder if that will persist?
