i have recently downloaded FUSION HDTV software which plays .ts files and they look incredible even on my pc monitor.

they look so much better than wmv-hd.

is this just because i am playing them on my pc or are they still much better than wmv-hd when output to a hd tv.

Never heard of it. Can you post a link?

Edit: scrub that. Just found it on your other thread.

The difference you'll see on the monitor is the differerce you'll see on the TV

I don't think .ts files are inherently better. WMV-HD files are possibly more compressed though, TS are typically MPEG2

I've only got two wmv-hd titles (We Were Soldiers and Total Recall) but neither are upto the standard I have seen via full length movie TS captures from US broadcasts.
The codec and the compression used are different of course and who knows how good the original source material was and perhaps until we see VC1 used on Blu-ray or HD-DVD any comparison may be questionable.

With identical bitrates, WMV should be markedly superior to MPEG-2 transport streams. But of course bitrates are not the same!

so does this mean that the quality of the hd pictures we see in comet like the formula 1 clip will be alot better than the broadcast pictures of hd when they come out.

is .ts the best hd feed but it just isnt practical because of the huge file sizes due to the better bitrate.

.ts is the actual stream capture isn't it? The files are huge which would suggest that.

if the .ts is the actual footage straight from camera does that mean that all the other type files are compressed and therefore lose alot of the quality.

There is no reason to assume that the actual HD broadcasts will be inferior to those clips or even demos used by retailers. Of course that's not to say that all HD broadcasts will be perfect, lets not fool ourselves

A .TS feed is a Transport Capture, the actual broadcast direct from the satellite, cable or terrestrial source. SKY+ and other DVR's do exactly the same thing by capturing the broadcast without any further compression or processing.

Yes.
The TS files you see around about are virtually identical to the original broadcast although other broadcast data (multiplexed news/weather etc) would have been stripped out.

The TS is not straight from the camera as such, any feed will be manipulated by the broadcaster at source even it's resolution can be changed as desired and inturn the optimal bitrate for the HD broadcast.
The TS that is captured by the PC will be what is broadcast to the viewer. That mpeg2 data file can then be edited to remove any content that is not needed and if required can be recompressed to an AVI using a mpeg4 codec which is were we get the 350meg and 700meg HD source captures from.

sorry to keep going on but is the quality of the .ts streams that i have played on my pc monitor possible to be broadcast by sky hd if the source footage is good enough. without any compression to degrade the picture quality.

As HD "out the back of the camera" is 1.5 Gbit/sec I cannot see Sky transmitting that!!

A typical Back haul to Studio link would be about 50 (Sat) to 100 (fibre) Mbit/sec MPEG2 as it codes quickly.

Emission rates are about 16++Mbit MPEG 2 in the USA - and wodul be about 5++ Mbit/s MPEG 4 pt10

only joking mate seems you are very well clued up about this type of thing.
so do you reckon the quality of the picture from say sky+ or blue ray will be comparable to the .ts feeds that are fed to hd displays like in comet.

Comparing apples and oranges. The .ts files are high bitrate MPEG-2 which is what is broadcast in the US. Sky will not be broadcasting in MPEG-2, but in H.264 (a variant on MPEG-4). H.264 is a much better codec than MPEG-2, which allows bitrates to be lower for the same quality picture.

There is no reason at all why broadcast HD would not be as good or better than the Comet demo.

I noticed that Panasonic HDTV panels are showing a short demo clip called

'Romantic Journey'.

Anyone know the source for this clip and any location I can download it from??


It's the best HD clip I've seen, showing the medium at its best.

SKY's H.264 (mpeg4) based system can match anything that is currently being broadcasting in the US (the primary source of the TS content).
SKY I suspect will do everything they can to make sure their HD service is flawless, there will be to many people in the press and industry out to criticise any weakness or compromise to risk anything else. HD is at the at end of the day all about picture quality, there are no economic savings to be made by adopting this format unlike the move to digital in the first place.

Broadcast HD is a compressed format anyway it's just that SKY's system and the future BBC service will be using a different codec one which has been ratified as a global standard and intime will replace mpeg2 on a number of US services.

Can't find any reference to it in the usual haunts which would seem to indicate it's probably an in house production, Pioneer and LG have their own HD demos as well.

is the link to .ts files

i suggest you download zoom player software off the internet and play the .ts files with that.

the formula 1 .ts files are a big download but the picture quality far surpasses the wmv-hd quality in my opinion.

There are those in the industry who say that VC1 (i.e. WMV) looks slightly soft compared with MPEG-2 (both at "typical" bitrates for each codec).
