TiVo HD Picture Quality Vs Freeview HD
 
I have noticed that the Freeview HD picture quality is sharper than the output of my TiVo.

TV set is a Sony 55W805C.

TiVo is connected to TV via Onkyo AV receiver using HDMI cables. TiVo is set to output 1080i. Sony TV set to Full Pixel mode.

I thought the picture would be the same however flicking between BBC one HD on either platforms I see a sharper picture on Freeview HD and a smoother picture from the TiVo.

I have used recommended picture settings as per the avforums video on YouTube for my TV.

Can anyone else see this?

My Freeview HD picture looks worse to me than the TIVO version

To be honest it's also smoothing out on Netflix compared to the app built into the TV too.

Have to say my Freeview HD quality is noticeably better than TiVo.

The BBC is required to supply the same quality of broadcasts irrespective of provider(freeview, cable, satelite etc). Any differences will come from the TV itself via picture settings that are specific to the source of the images (internal freeview, HDMI etc). Eg my 3 year old Samsung has a "Game Mode" setting, which obviously doesn't apply to the internal Freeview picture.The option says that it may degrade picture quality. The TV may do the freeview decoding and upscaling in the same chip, which means the upscaling might be different between freeview and external HDMI source.

Same tv settings on both inputs, Freeview is better than Tivo. Just on HD, SD they're the same.

The "Game Mode" setting on my TV is not in the picture settings. It is hidden away in the System, General settings.

VM use the Astra satellites for most SD feeds, but HD channels are usually supplied direct to the Super Headend at Langley on an uncompressed fibre feed from the broadcaster.

There is a noticeably softer picture from my TiVo STB and I find it unusual that all HD channels are not as good to watch via the TiVo when compared to Freeview HD.

There is a (legal?) requirement that the BBC supply the same quality level on all platforms. Freeview, VM, Sky, etc will all be the same.

Some Freeview is in 1080p. Having said that, my Sony's BBC HD channels look better than my TiVo's. C4 looks better on TiVo. ITV is not notably better on Frreview unless it's a 1080p programme.

Of course you meant 1080i ,1080p broadcasts in the UK don't exist .:dunce:

I'm in two minds whether to try Sky and their new Q box to see if this improves my experience because I don't feel I'm getting good value for money paying out for kit that doesn't deliver a decent picture. Or wait for the V6 STB from Virginmedia.

And possibly find that the "problem" is still there as it's related to whatever is plugged into the HDMI ports.

True, there is a possibility.

Freeview HD channels often broadcast in 1080p. ITV and Channel 4 appear to use it most frequently. I was surprised the BBC didn't use it for the Rio Olympics.
It's been available of Freeview since 2011.

Indeed, http://www.bbc.co.uk/blogs/researcha...bc-hd-on.shtml caused a few issues at the time with sony tvs because they maintained different settings for each picture type mode.

no they don't
Sky is UHD not 4K Sky also say its UHD.

BT say its 4K but it really is UHD.

HD is 720 to 1080

UHD is 2160 to 3240

4K is 4320.

Out of interest do VM honour 1080p broadcasts when they're available?

Are you in agreement of the systems they use to delivery these higher resolution signals?

yorkshireborn 08-10-2016 16:54
Re: TiVo HD Picture Quality Vs Freeview HD
 
they get the signal from the source its wot they do with the signal when they get it and resend it to us.

you could compare it to a tin of beans there all the same ingredients, but all taste different.

No, broadcast HD on VM is always 1080i. The V+ and V-HD boxes don't support 1080p.

The only 1080p available on VM is from Netflix.

Have to say that Sky Sports 1 HD is bad today.

Not sure if its down to the host broadcaster as watching the football or down to VM

I asked about how upscaling was done by the STB/TV on a technical forum and was told that the STB/TV plays no part in upscaling as this is done completely by the broadcaster and it just reproduces the feed it's given.

When I asked if upscaled material used the same HDD space as true HD material when recording, I was told that it actually uses more!

I have read people say on forums that XYZ box is good at upscaling though :confused:

Just type into Google - what resolution is 4K. Or to save you some time, here is a link from that search... Which shows it isn't 100% straightforward

I'm absolutely sure some BBC Freeview Broadcasts are 1080p on the T2 platform.
This has been discussed on many tech sites.

Digital Cinema 4k resolution is 4036 x 2160.
4k UHD Resolution is 3840 x 2160.
I'm sure that BT say 4k UHD which is correct.
My TV will take the larger resolution of 4036 x 2160 and ignore the extra vertical lines so the picture shows with no stretching or shrinking.

Ultra High Definition, or UHD for short, is the next step up from what’s called full HD, the official name for the display resolution of 1,920 by 1,080. UHD quadruples that resolution to 3,840 by 2,160. It’s not the same as the 4K resolution made above — and yet almost every TV or monitor you see advertised as 4K is actually UHD. Sure, there are some panels out there that are 4,096 by 2,160, which adds up to an aspect ratio of 1.9:1. But the vast majority are 3,840 by 2,160, for a*1.78:1 aspect ratio.

that paragraph alone tells you its different.
