DTT - Rabbit Ears

pandaboy

Hey, I've only just figured out that Saorview has been available for the last few weeks and I've basically set up my tv - Philips: mod. no. 32PFL7762D with a set of rabbit ears to basically store the channels.

I have installed the frequency settings - 666MHz (I'm based in Cork City and I working from the Spur Hill Transmitter). Everything appears fine - Service Provider RTE NL appears and signal quality is excellent. Though when I look to install services (these are channels I'm guessing), zilch appears.

The TV supports DVB-T and the aerial I am using supports UHF-VHF-FM.

I have checked other threads and I noticed one person used a software update to solve their issue, though there is no PC input in the tv and when I registered with Philips there is no mention of a software update for my television.

I'd really appreciate it if someone could help me out with this.

I looked up the specs, the TV supports DVB-T alright, but only MPEG2.

The RTE transmissions are MPEG4.

Aha, that explains why it tells me to go back to analogue mode so.

Thanks for that.

Would a set top box solve this or does the tv still need to support MPEG-4 for a set top box?

A set-top box would sort you out alright. The box will decode the signal, and connect to your TV over HDMI or Scart.

I think there's only two officially approved now: http://www.saortv.info/terrestrial-saorview/saorview-reception/

But there's a good few out there that would receive the pictures, I'm sure someone else can give some better advice.

no. The Setbox does everything. Just uses the TV as SD monitor (SCART) or HD monitor (HDMI).

That's super stuff, thanks guys.

It'll be HDMI all the way methinks. What is the max res for HD? I'm assuming it's not full 1080P? They're working off of 720p?

watty

1080p and 720p is for Americans with their horrid 24fps to 30fps pull down issue.

Europe is all 1080i 25fps / 50Hz Broadcast. Same sharpness as 1080p

pandaboy

Oh right I assumed it was vice versa. Though I've mainly worked with SD only when working on camera for tv work.

Is RTE strictly Interlaced because I have shot some progressive stuff for them before and I couldn't see them performing a conversion of the final footage (unless it's converted at broadcast).

Ah, good ole' framerates. T'isn't PAL just great

watty

Only Film is progressive. It only matters in 30fps countries.

NTSC/30fps is the really nasty stuff.

You'll see a hum bar on some Analogue TVs if you feed them NTSC in 50Hz world, or PAL in 60Hz world. That's why TV is not universally 24fps interlaced 48Hz. (which would be perfect for film and artifically "double" the apparent film shutter speed of 24fps (progressive). Everywhere would have had hum bars. So problem was not either film choosing 25fps when upgrading from 12fps to 18fps to standard, or universal AC mains at 48Hz instead of 60Hz and 50Hz.

If you thought 405, 441, 525, 625, 819, 1125 lines and SECAM, PAL, NTSC and 60Hz PAL was bad

Just looking at that there, near the end in the sentence about HD. Shouldn't that say 1280x720? It says 1440x720 twice.

watty

Ta

yes 1280 is normal "square pixel" 720p
1440 x 1080 is anamorphic pixel 1080i or 1080p
1920x 1080 is "square pixel"
