Compression/bandwidth on 118.7 sat

[andyg]

Too much green coloring, esp on 118 sat?

ok, guys.

Maybe I am just paranoid and need to have my eyes checked. But, I have noticed too much green coloring on some channels (especially 118 sat international, but also on others 110/119 except HD 129). It is more visible when viewing on HD tv or through my PC, but also is a little visible on SD TVs. What I mean by green coloring are either some green shadows in different places or just in general picture has too much green color in some areas or in general. Yes, I checked all the color temperature on my TV, etc. so all the TV settings are fine.

So, is it bad LNBF, bad receiver, too much compression, poor quality of channels being broadcast, etc.?

let me know what you think. Also, do in general channels from 118 satellite have worse picture quality then say 119?

thanks

Blurry picture on RES channel 712 (118.7)

Does anybody else get really blurry picture on channel 712 - Russian Extreme Sports off 118.7 sat?

thanks

Oh, my. I feel for you. The problems is that all the Internationals at 118 are blurry to some degree. The problem is Dish is really cramming all the internationals and some LIL onto the AnikF3 at 118. In other words Dish is compressing the heck out of all the video. TV5, Eurochannel, Euronews, and every other international that I have seen in free preview is "blurry." Very sad because my internationals had better PQ at 148. Yes, the blurry PQ is bad. However, I noticed that some channels are a bit less blurry than others. This is a Dish compression problem, and that means we probably have to live with it until Dish improves the PQ in someway, perhaps better encoders or the forthcoming plan to use 8PSK for all Dish channels.

Sorry, but that's the way it is. Stinky blurry. Happy viewing.

Anybody knows if compression is too high or bandwidth is too low on the 118 sat (international channels)? the pq looks too poor.

thanks

Unfortunately thats the way many of the channels are sent over to the USA.

A number of the channels are in the clear and can be received with a Free To Air satellite system, and those look just like the Dish Network feeds.

There is nothing Dish can do about it, garbage in, garbage out unfortunately.

sounds good..I mean frustrating..but nothing can do about it. So, you don't think that blurring is my LNBF or singnal strength/quality of the dish.

merged three threads together

opening multiple threads with the same thing isnt going to get your question answered sooner

thanks man..stil wondering about those green colors though

There's also probably some sort of mismatch in the US-RU colorspace correction standards.

 

[highdefjeff]

What is your signal meter reading and where are you located?

 

[harshness]

No amount of signal strength is going to improve a picture that isn't breaking up.

It is possible that your receiver has developed a green bias, but not likely.

 

[aklarvanto]

Could it be also due to PAL/NTSC convertion?

 

[whatchel1]

Standards conversion can cause color shifts. It's not a signal strength issue. It's also unlikely that it is the compression applied to the sat system. The blurriness and color shifts are due to the conversion process and then how it's delivered to E* for rebroadcast.

And there really isn't a bandwidth crunch on the 118.7 bird either. If they were hurting for bandwidth really bad they would have already pulled the HD locals there that are on one or two other birds. Plus they are not using 2 TP's there already.

 

[Mr Tony]

I've seen weird colors on some of the ethnic channels that are available free to air. Its just how they are getting the signal

as Scott said...garbage in...garbage out

I have to disagree somewhat, Scott. My French internationals are 148 were quite good SD quality. Better than some SD at the core sats. Also, many of the internationals have greatly improved their PQ, probably working with Dish to improve the PQ. free previews at 148 had really good SD quality. TVJapan was great; TV5 very nice; I would see a preview of a an international that used to have poor PQ, but looked great later at 148.

This is a massive compression problem at 118. TV5 and Euro channel look like cr#p, as well as just about every other international. Considering the high quality that TV5 and TV Japan had at 148, one can only conclude the diminished PQ is a Dish problem. Perhaps when they get the LIL's off of 118, it might improve.

my 118 are in 50s and I am in Kentucky

I think this totally makes sense...the compression problem on the Dish's end.

any idea what green bias is?? I hooked up my second receiver, and it was doing the same thing. So probably it is not the receiver.
I agree about the signal strength. I have some channels with lower signal strength on those tps as others that are higher, and their pq is much better.

some of the channels look good but some of the channels the originating feed does look like crap.

Also when Dish moved from 148 to 118.7 they went from a DBS sat to a KU Band sat. KU can't have as many channels on a TP as DBS can but Dish crammed the same amount of channels on the KU sat

so 10 gallons of crap in a 10 gallon bucket.....ok
cram that same 10 gallons in a 7 gallon bucket and well......you get the drift
