RTE One HD and TWO HD

euser1984

Can anyone tell me what resolution these are and even though they are marked HD are they the equivalent to what you would get from a Blue ray?

Thanks.

1440x1080i. I think the bit rate is capped at 8 or 9Mb/s so it would be significantly lower quality than Blu-ray.

Would it be less quality than a proper 720p video? Thanks.

It will be far from Blu-ray quality but good all the same.( I'd be go smacked if it was as low as 8mbps Karsini.)

HD is a broad term and as Karsani alluded too resolution can be very misleading. Two 1080p signals can vary massively in image quality.

Is there any reason you ask because perhaps we could be more definitive if we knew.

The main reason I asked is because we have a new tv and I haven't tried watching a file from a disk or blue ray; although I have watched hd films on other tvs and my laptops.

Compared to what I saw in the past I was disappointed with rte one and two and was hoping that the new tv wasn't sh*te...

Ah okay.

First thing I would suggest is having a quick look into the picture menu. Don't worry, it's really simple and you can't do any damage.

It sounds like the picture is not set up correctly and this can have a massive influence on how good the picture is. Try lowering the brightness and contrast.

There are loads a step by step guides online so I would try that.

OK, I was reading up on getting some calibration cd. Have you any experience with that?

AndersKP

Yip, are you getting the THX disc and glasses?

Ps what TV have you got?

The official spec says:

Capacity Required for HD and SD Services

The following technical specifications are being proposed by RTÉNL and are subject to contract negotiations with broadcasters.

Statistical multiplexing will be used for all video services, audio and data services are fixed bit rate. It is planned to use the following bit rates as part of a statistical multiplexed pool.

High Definition Video (HD)
1 Minimum of 2.0 Mbps
2 Maximum of 9.0 Mbps
3 Weighting 90%
4 Resolution 1440 x 1080i
5 Expected average bit rate 6.0 Mbps

Standard Definition Video (SD)
• Minimum of 1.0 Mbps
• Maximum of 8.0 Mbps
• Weighting 90%
• Resolution 544 x 576
• Expected average bit rate 2.0 Mbps

Audio HD and/or SD
• Main program audio 192 kbps (stereo)
• Secondary program audio 96 kbps (mono), if required.
• Access services 96 kbps (mono), if required.

Wow. Thanks for sharing, that's very low & the beeb isn't much better. True to my word, I am gobsmacked!!

Should still hold up well on a decent panel though with regards to the OP

This is the one I was considering getting because there is a tutorial on lifehacker.

I wish I had the model number to hand but it wasn't bought online - all I can say is it was one of the lower end Sonys....it's at the parents house so they didn't want to go all out...

To be honest I've only ever properly used the THX optimiser but I'm sure it's much the same

Once the disc is playing it's pretty much step by step. It will show you images and ask you to adjust brightness/colour to a certain level. For example reduce the contrast until you can't see a symbol
