HD picture looks very soft.

It's not even proper HD, it's upscaled SD according to the programme synopses.

Graham, your images in post #21 are missing. Did you upload them? or did you copy and paste the text containing the images?
 
It's a copy and paste of programme details. Any images will only be channel icons which do appear in my browser. Most odd

The significant info is Upscaled SD
 
Black Hole roughly how long will it take to auto-decrypt the very short recording segment of Midsomer Murders so I can have a look at the contents ? I have a thumbnail file now

It has to have been DLNA indexed before it will decrypt. Alternatively do a manual copy to USB (auto-unprotect should have kicked in pretty quickly).

What platform - Satellite or Freeview.?

As already said Freeview HD has 1080p25 content. If it's your HD FOX T2 do you have the output scaler set to de-interlace (1080p). If so your TV will report 1080p because that's what it's getting.

Recording a bit to see what the actual broadcast is.

It's Freeview using the TV tuner. It thinks it's getting 1080p.

Second half about to start!

Of course I know the difference, you clearly do not

Interlacing versus progressive has nothing to do with picture resolution.

1080i sends 1920 x 1080 pixels in two chunks known as fields. In the UK this consists of lines 1 3 5 etc (odd lines - upper field first), followed by the even lines 2 4 6 8 etc.). Each field is transmitted in 1/50 second. In 1/25 second you have a full frame of 1920 x 1080 pixels. The TV will produce this frame in a process known as de-interlacing. All HD broadcasts in the UK now use this system apart from some Freeview-HD content (more later). There may be a 1/50 second between the generated data for each field, this gives the slight jagged edge unless the two fields are derived from the same image as they would be from a movie created from the original film stock. This creates an identical image to 1080p25.

108op25 simply sends the data progressively line 1 2 3 etc. The whole frame takes 1/25 second.

You are expressing a misunderstood myth perpetuating the Sky installers dodgy advice (They aren't Engineeers simply tradesmen taught how to install a satellite dish a task that's not very difficult).

When 1080ps is bandied about they mean 1080p50 which has the full resolution of 1920 x 1080 pixels and the 50 frames/second of 720p50. There aren't any 1080p50 broadcast sources. Many HD Video Camcorders/Digital Cameras and DSLRS can shoot in 1080p50 format (I have 3 such devices).

Deleting a load of video data and then guessing what was deleted is ridiculous.

Wow you do know! I love all your number crunching, but how come you still don't know why my picture and others is sharper on 720p? Your very much a two plus two equals four type of person, when something's happening that doesn't add up your lost! So the sky installers dodgy advice to leave it on the clearest setting was wrong! Just like mine everyone could see it was better. Well I guess that's fine, you go by what the numbers say, and we'll go by how good the picture looks.

I'm an Engineer not a Sky Fitter. They say there's one born every minute :)

Now if your Samsung actually has a 768 line panel that would explain it. What model is it ?
 
Seeing as this discussion as branched out somewhat, am I correct in thinking there would be little difference in the bit rate for an up-scaled transmission compared to the original? It seems to me that decoding the data over a larger number of pixels in the frame results in up-scaling as a side benefit.
 
You are correct the bitrate is similar and stat muxed over the other HD channels. The measured bitrate for the clip was 8672Kbps which is quite high for a HD channel. It's also likely a broadcaster has a much more expensive and superior encoder than you will get in domestic kit.

The same broadcast on ITV1-SD would have a much lower bitrate, the best SD channels in the past used up to 7000Kbps, they are now much lower. Channel 5 is dire, a result of simply squeezing too many channels into the available bandwidth. The worst SD 576i channels have a resolution of 544 x 576 pixels (Yuk :eek:) BBC channels are 720 x 576 and ITV 704 x 576 (no practical difference at all)

Mind you domestic encoders have improved dramatically in recent years.

I have an expensive Denon DVD player some years old that has what was considered the best scaler available (Made by Faroujda), a newer Sony Blu-ray player costing less than a third of the price makes DVD's look significantly superior than on the older Denon. Indeed one THX test DVD I have is hard to tell from Blu-ray when upscaled by the Sony, unless you get very close to the screen and then of course you can see the inevitable scaling artefacts.

I only keep it because the Denon sounds dramatically better playing CD's than the Sony.
