WFSB Picture Quality

[dx1ng]

I've been watching WFSB DTV here in Poughkeepsie lately, and I notice on channel 3.4 the picture pixel-ates (tiny squares) with any movement. This is not the same as a picture lock up due to a fading signal... I don't experience that at all on channel 3. Also, the sound is out of sinc on 3.4... the dubbed Japanese movie effect, with the sound noticeably delayed compared to the picture. Is this due to my converter box, or does everyone have these problems with 3.4. Also, on channel 3.3, the small picture boxes have that same pixel effect. The picture (and sound) are excellent on 3.1 and 3.2 however.

Surprised you're even getting WFSB-DT that far away! Anyways, what you just described for their subchannels is correct. I get the same thing with either an Insignia digital convertor box or an indoor rabbit ear attached to my Sanyo 26" LCD HDTV directly.

3.1 would look even better if they 'd just ditch the 3.2, 3.3, 3.4 etc.

Isn't that the big advantage with DTV is the subchannels with weather and news, classic shows, reruns, sports, etc.

I suppose it is unless you like HDTV. Add just one subchannel and the HD looks like cable HD

That is actually fairly common, the less important the sub channel, the less bandwidth they allocate to it. I havent looked at WFSB on an analyzer yet, but it sounds as if they have the BW clamped down.

While I was toying with my -2 encoder, I brought it down to 1.5MB and up to 15... of course you know how each looked. I have them both set at 9MBPS (18 MBPS total, + some overhead for PSIP, etc) = 19.xxxx MPBS ASI stream to the encoder.
