DStv HD improvement

I bet you they will not stop charging you even though your decoder is not up to scratch. Not unless you tell them to. People should keep their fingers on the number for calling up the Credit Protection Act people so long.

Hummm...

Huh??
I think your brain slipped pass the IPA (idiot protection act)

Note that your viewing environment has to be set to "all channels" to access channel 425. Press the TV button to check your viewing environment. I had mine set to "my channels" initially, and kept getting an error message.

You da man...sweated a bit when I couldn't find the channel.
 
So what is it that the installers have to do to fix the problem?

I am just glad to see the DSTV dish that i installed works perfectly :P
 
I tried the channel 425 and get a picture - some humming bird. So I guess my setup is a-okay.

Although my TV is only HD ready - so I am missing out. That will change soon when I upgrade the TV though.

So does this mean more HD channels and at a better quality? (Higher res? )

More channels, maybe less compression. Not higher res.

I believe the motivation is more HD channels (or HD simulcast of existing ones).

As far as quality goes we'll have to see what, if any, difference the switch from DVB-S (MPEG2/H.263) to DVB-S2 (MPEG4/H.264) will make. There will not be any change to res at 1080i.
 
Problem is that this image doesn't look very HD to me.

They have been using MPEG4 for HD, since the start of HD in 2008... This change is for the modulation and not the compression. QPSK changes to 8PSK.

Strange, I thought MPEG2 compression was a mandatory part of DVB-S spec?

Does the modulation changes alone provide significant bw saving, otherwise what would be the point?

They are running hybrid.

DVB-S is MPEG2 with QPSK.
DVB-S2 is MPEG4 with 8PSK
They are using QPSK with MPEG4 for HD, until month end.

Quantum Theory said:
They are gaining quite a bit of bandwidth actually... 30% performance gain from QPSK to 8PSK and 5 of the 19 transponders will now be DVB-S2. Obviously they have been using MPEG4 for HD since 2008, so no gain there.

So do we need a bigger dish to receive this, I seem to have the standard size on my roof.
 
I have a pretty small dish, seems to be fine.

I couldnt find the channel last night, will try again today after work, I have a pretty big dish, signal strength and quality are not below 90.
 
I think this is going to cause MC lots of ***.
I can picture most of their subscribers going dark.
