I am going to start tinkering around with FTA Ku band. Is NHK World still on SES3? Lyngsat doesn’t show it, but ftalist says it’s there. Anyone know for sure?

is it just my impression, or did the bitrate of NHK go down significantly when it moved to its current transponder? The picture quality used to be great and now I find it very mediocre compared to what's on 58W.

They are running in 960x720p instead of 1280x720p video formats.:rolleyes:

I presume they are using full1080i on C-band on 58W* bird?:)
true, but i'm referring to the ugly artifacts that we see on moving stuff, typical of a low-bandwidth stream, independently of the actual stream resolution. I don't remember seeing those on those channels when they were on the old frequency.

Often, a SD channel with a decent bitrate looks better than a bit starved HD channel, unless the motion is slow or inexistant

Is it one of the mux channels? I scan in 4 channels that say no name on the geosat that are 24/7. Not the nbc mux, but some sort of other mux titled no name.

Sounds like some of the OTA channels in my area. The SD subchannels multiplexed along with a 1080i main channel often artifact quite a bit. 6Mhz is pretty narrow.

Yep it adds up to about 19.3 mbps total bandwidth. Depending on what the .1 channel is, the subchannels can be offered quite a bit less bandwidth and thus be subject to more artifacts and poor PQ.
