Well, the encoder is likely in donnybrook. So I'd be surprised if everywhere isn't the same.

RTÉ's plan is to use approx 2 Mbps for SD channels and 6 Mbps for RTÉ 2 HD. The capacity of our muxes is 24 Mbps, so we could fit 4 HD channels @ 6 Mbps in a mux. Radio channels are allocated between 96 and 128 kbps.

Home and Away in HD on a non HD TV isn't any more interesting, surprising that.

12 SD channels per MUX
or 4 HD channels per MUX
Radio channels around 30 per MUX??? I think I am wrong with that???

1. RTÉ One ~ 2.5Mbps
2. RTÉ HD ~ 6.3Mbps
3. TV3 ~ 2.5Mbps
4. TG4 ~ 2.5Mbps
5. RTÉ News ~ 2.2Mbps
6. 3e ~ 2.2Mbps
7. RTÉjr/RTÉ+ ~ 2.2Mbps
200. R1 ~ .1Mbps
201. R1Xtra ~ .1Mbps
202. 2fm ~ .1Mbps
203. Lyric ~ .1Mbps
204. RnaG ~ .1Mbps
205. Pluse ~ .1Mbps
206. 2XM ~ .1Mbps
207. Choice ~ .1Mbps
208. Gold ~ .1Mbps
209. Chill/Junior ~ .1Mbps
Digital Aertel ~2Mbps
Management ~1Mbps
Total ~24Mbps

Are we thinking that RTÉ 1, 2, TV3 and TG4 will take up one mux in HD?

I will delete this if any of this is wrong.

This is RTÉ's planned Mux 1 with bit rates

A/D (while low) goes after ASO??? Also I thought all RTÉ channels will have Digital Aertel, RTÉjr/RTÉ+ doesn't seem to have it.

Again for the second Mux what do we expect that SD channels and Radio will move to Mux 2 while on Mux 1 we will get 4 HD channels. (Long term future).

I am receiving from CH and I don't see what you are getting, all channels working fine with me

watty · 02-12-2010 08:54PM

Analogue is OK. It's the digital.

Elmo
It makes more sense actually to mix 2 x HD and 5 x radio on each Mux.

channelsurfer2 · 02-12-2010 09:00PM

so is this a permanent thing or will it be intermittent testing of rte2hd? whats the guesses at this stage? its pretty impressive the wildlife programme on now.
Ps I was in tesco tonight and they had all their mpeg4 tv's showing tv3 from the DTT tranmission.(all the others were showing sky news or turned off).

A/D = Audio Description.

All RTÉ channels will have access to MHEG-5 Digital Aertel with the correct receiver. Text refers to traditional EBU teletext which will only be carried on RTÉ 1, TV3 and TG4.

No official plans have been announced for the second mux.

There are no issues now.
All the encoding is done at Donnybrook - everyone receives the exact same broadcast.

All these TLA's can't keep up, I thought EBU stood for European Broadcasting Union and was in realtion to EuroNews :rolleyes:

The list you provided suggests that RTÉjr/RTÉ+ won't have Digital Text.

So can we speculate as to what we will see on the second MUX?

2HD, 5Radio, 3SD on both muxs meaning some movement in the future.

Mux 1 (speculation on arrival of Mux 2)
RTÉ 1 HD
RTÉ 2 HD
RTÉ News Now SD
RTÉjr/RTÉ+ SD
OTHER 1 SD
RADIO 1
2FM
Lyric
RnaG
RADIO 1 Extra

Mux 2 (Speculation)
TV3 HD
TG4 AS
3e SD
IFB/OTV SD
OTHER 2 SD
2XM
CHOICE
JUNIOR/CHILL
GOLD
PULSE

LOL at A/D on TV3 they can even get 888 working.

watty · 02-12-2010 10:29PM

The Film Channel and the Oireachtas Channel are sort of pencilled in.

Mux 1 (speculation on arrival of Mux 2)

RTÉ 1 HD
RTÉ 2 HD
RTÉ News Now SD
Film Channel (if HD at night, News Now to slide show)
2XM

Audio all on AAC+ stereo instead of MP2 saves 1Mbps per mux?
Who knows!

Text in that extract above refers refers to traditional EBU teletext which will only be carried on RTÉ 1, TV3 and TG4 at a bit rate of 300 kbps per channel.

Digital teletext appears under the heading "Interactive" - "Digital Teletext" at a bit rate of 1.000 Mbps and will be accessible from all RTÉ channels incl RTÉjr/RTÉ Plus.

watty · 03-12-2010 12:19AM

300kbps sounds VERY luxurious for Teletext. I had an idea that it was pretty slow

In the case of the Ceefax and ORACLE systems and their successors in the UK, the teletext signal is transmitted as part of the ordinary analogue TV signal but concealed from view in the Vertical Blanking Interval (VBI) television lines which do not carry picture information. The teletext signal is digitally coded as 45-byte packets, so resulting data rate is 7,175 bits per second per used lines (41 7-bit 'bytes' per line, on each of 25 frames per second).
... using lines 6–22 on the first field and 318–335 on the second field. [ = 16 lines x 50 per second)

via http://en.wikipedia.org/wiki/Teletext

http://www.mrgsystems.co.uk/info/6.htm

one teletext packet comprising 45 x 8 bit bytes is transmitted in one TV line. Most broadcasters dedicate around 8 datalines per field for teletext transmission.

45 x 8 x 8 x 50 = 144,000 bps

So 288kbps is as if 16 lines per field are used.

Hmm.. more than I imagined

Given cost of 28.2E sat I see now why BBC is dropped it. Same space as a decent quality Radio Channel, or two dopey quality Radio channels.

On digital there are NO blank lines, hence 480i = 525 lines, 576i = 625 lines and 1080i = 1125 lines (if there was such a mysterious beast as Analogue, well there are or where HD CRTs, and they need time to get spot back up to top. VBI = Vertical Blanking interval.), so teletext being totally digital, as happily has its own stream in the MPEG-TS as lives in "blank" analogue TV lines in the VBI.

Film and Oireachtas Channel = IFB/OTV

I assume that OTV would only run during daytime hours leaving the evening free for IFB.

watty · 03-12-2010 03:52PM

they do have debates in evening

But maybe a reasonable assumption.

watty · 03-12-2010 09:34PM

Shorthand for EBU Teletext. I.e. the BT/BBC invented 1970s digital Teletext that is on Analogue TV sets

You need MHEG5 to get the new text service, listed as "Digital Teletext" at the bottom 1.000

endakenny · 03-12-2010 10:15PM

Thanks!

Manc-Red · 06-12-2010 07:59PM

The penciled in Movie Channel, anybody any info if this would be in HD if it is indeed given the go ahead on Saorview?

watty · 06-12-2010 08:49PM

It awaits
1) Money from the Irish Film Board thingy
2) 2nd Mux

Likely HD depends on Money, costs, Mux Space.

I agree, it ought to be HD.

In theory BAI has to approved it. They will spend X months humming and hahing so that it looks like they are important and in control and then they will approve it.

Manc-Red · 06-12-2010 09:13PM

A HD Film Channel would be a very welcome addition to this service, SD just wouldn't do it justice imo.

The proposed channel would be made up of mainly Irish and European Film rather than American Blockbusters, it may include some other world cinema. It was also supposed to run without advertising but that is mainly down to the IFB/BSÉs chairperson and former chairperson and co-founder of TV3 James Morris.

Here is their VOD channel http://www.thisisirishfilm.ie/shorts

In relation to RTÉ Two HD as it is currently broadcasting, how does it looking on HD TVs? I am assuming that it isn't really broadcasting in HD.

I would have thought that the BAI have no control in relation to the IFB/OTV channels since they are in the Act. The money is what is required.

Machinehead · 06-12-2010 10:25PM

Watched Kingdom of Heaven on RTÉ TWO upscaled to 1080i last w/e & Con Air on BBC HD 1080i. (TX-L42D25L HD LCD Panny) The difference was obvious, clarity & depth were clearly better on BBC HD. It has been posted here that RTÉ as yet can't play/transmit recorded HD programming but possibly have a live HD play thru' capability (I think that's the phrase), waiting to see if they will transmit (play thru') the football content of the Champions League game on Wednesday in HD.
On the other hand, if RTÉ don't have the capability to transmit recorded HD programming, how were they able to transmit the HD video loop on the RTÉNL channel for the tests? Maybe someone can explain.

In comparison to the SD channels? I also think they may need to get HD rights for movies

Kensington · 06-12-2010 10:37PM

Don't know if they have the HD rights to this season's Champions League. Of course, the programming guys in Donnybrook may go and pleasantly surprise us - here's hoping anyway

A professional grade PC with an HD-SDI output interface patched straight into the encoder would provide a basic test loop like that on the test channel. The scheduling system and more specifically the VTR's they use to play out recorded programming isn't HD capable, although they are in the process of moving to a tapeless environment which will be HD capable.

watty · 06-12-2010 11:21PM

A long time since "James Morris" was editing Guinness ads on a pair of U-matics in Georgian Terrance near St. Stephan's Green. Then Some fun installing an old cinema projector with telecine adaptor in the paint-still-wet Windmill Lane.

In those days people lucky to get 1.5 channels here.

AMD64 Athlon off the shelf I was playing pre-built TS file with 5 channels into PCI DVB-t modulator over two years ago.

If you have an ASI out PCI card you can play a single HD loop (pre-encoded) into your Mux and use any old PC.
