When the OTA analog shutdown finally happens, will the DirecTV SD LiLs be turned off, or will they be replaced with the HD versions? If they are shut off, doesn't that mean more space for potentially more national HD channels???

The SD channels will remain to service the millions of SD-only receivers out there. However, they will be fed by the digital channels not the analog ones.

All (or nearly all) of the SD LILs are already using the digital signals from the stations. Here is the conversion schedule: http://mstv.org/docs/satschedalpha.pdf. I recall seeing that Directv kept the analog feed on a few stations (mainly PBS) which hadn't yet upgraded their digital signal to mirror analog programming. The SD signals are typically center-cut versions of the HD broadcasts, but some are apparently letterboxed.

Since it is digital until it gets to DirecTV, would it be safe to assume that these SD feeds from D* will be higher quality than the current, analog-fed SD feeds?

It depends how they are encoded and sent to the satellite. If they use the same encoders the quality should be the same.

Since DirecTV has been digital don't think you should see a difference.If you are and I am too.It's a downrezzed MPEG2 HD channel.The colors are deeper the picture and faces have a little more definition.It's definitely a better looking SD picture.Don't know if it's DirecTV's doing or the station but I like it!.:)

I noticed some improvements--mainly less ghosting and better color fidelity. You can still see a big difference compared to digital OTA.

Also not to nitpick, but most of us that previously had SD locals on 72.5, are/will NOT be getting SD feeds of any locals up in MPEG4 HD. D* will be using ONLY the HD feeds of these stations for SD only viewers, of whom will require all MPEG4 receivers (R22 for DVR's, H2x receivers for non-DVR receivers), which then can downconvert the HD signal in the receiver for an SD TV.

I think we'll see more Mpeg4 only locals markets in the future too. I wouldn't be too surprised to see all new markets DirecTV adds to be Mpeg4 going forward. In those markets I'd expect only 1 version of the channel to be provided as you described. Only the HD if it's available which will be downresed by the receiver as needed or the SD version if that is the only version available.

True, the last batch of SD local markets (about 1/2 dozen) were done in MPEG4 SD only, such as Palm Springs, CA. Some of them are now getting ready to "convert" to HD, which will mean the same thing like the 72.5 markets I just described.

There is really no reason for D* to waste sat bandwidth putting up a 2nd copy (SD) of every HD local channel out there, when the end-user's receiver can accomplish the same thing - at least for all new markets &/or ones migrating from 72.5, which has been D*'s gameplan all along. ;)

Yup it's part of their slow march towards all mpeg4 equipment and a pretty good way to do it. Markets with out any locals are likely to have much fewer subs so very few legacy receivers to replace.

I'll predict that sports packs like sunday ticket will go mpeg4 only even for SD too. We may even see that as soon as next season.

There are some stations that have shut off their analog signals already. In the Portland/Auburn, ME area, our CW and MyNetwork are ONLY broadcasting digitally.
