BBC HD to switch to DVB-S2 on 6th June 2011

The BBC will switch to the higher-capacity modern modulation scheme for the BBC HD and BBC One HD channels on satellite.

The BBC will switch to the higher-capacity modern modulation sc
published on UK Free TV

The high definition (HD) television channels on satellite require a lot more bandwidth (number of bits per second) than the standard definition (SD) ones, as you might expect.

However the additional capacity required is reduced in two ways. First the MPEG-4 compression system is used (rather than MPEG-2) and generally the DVB-S2 modulation system increases the bandwidth of each satellite transponder.

Generally speaking, around nine SD television channels can be carried on a transponder in DVB-S mode, and four HD channels on one in DVB-S2 mode.

For historical reasons, the BBC's Astra 2D transponder 50 has been providing BBC One HD and BBC HD (and also ITV1 HD Merdian South) in the DVB-S mode, and this has used all the capacity on the transponder, because of the lower bitrate.

The changes

One 6th June 2011, the BBC will switch the transponder to DVB-S2. If you watch using Sky+HD, Virgin Media or Freeview HD you will not have to do anything.

If you use a branded Freesat box (or TV set), you may need to put it into stand-by mode for 30 seconds on 6th June. If that doesn't work, perform a 'first time installation'.

Update: Some Panasonic Freesat boxes are unable to deal with the change - see comments below

If you are using a unbranded Freesat box, you may find that you also have to do a 'first time installation' to get the channels back.

Some older satellite equipment will not support DVB-S2. If you can't watch Channel 4 HD, then you will no longer be able to watch the BBC HD channels.

Sky HD, Freesat HD EPG issues

Currently BBC One HD cannot automatically replace BBC One in the Sky EPG at position 101, because there are 15 regional versions of BBC One, and only a single BBC One HD 'stream' on the satellite.

BBC Two carries four regions for England, Scotland, Wales and Northern Ireland. For a BBC TWO HD to appear in the Sky EPG at position 102, the BBC would need to provide four versions of BBC TWO HD.

All the other BBC channels are national, and have no regional components. BBC Three timeshares with CBBC, BBC FOUR timeshares with CBeebies, plus there is BBC News, BBC Parliament and BBC Alba.

The extra capacity found by moving to DVB-S2 could allow the BBC to provide BBC Three, BBC Four, CBeebies and CBBC channel in HD, and these could be provided in the "usual" EPG slots for Sky HD and Freesat HD users, which would put them on the lower numbered channels nearer the top of the guide.

Barry: Yes, Les Nichol's suggestion of trying a manual set up is a good idea, I suspect though that it may be the 23000 symbol rate setting that might cause a problem as thats not offered as a choice in some equipment, so will be interested to learn whether or not it does in your case.

Have recently purchased a panasonic
DVD Recorder model DMR-XS350EB. All appears to work OK but not being particularly clued up on these things, realised that I was unable to play back a recording made earlier from a broadcast that a child lock was in place and therefore no joy. I certainly do not remember entering a PIN for this function. I.D. PIN yes. Could anyone tell me please how to unlock as we do not have any children to concern ourselves with regard to watching banned channels. Many thanks.
Ray Thomas.

Hi jb38, Les,

Yes also tried the manual search but compltetly dead. No sign at all. Do you think there is any chance I need a bigger dish? (I do have evening problems with some of the C4 channels so maybe the "new" BBC1HD needs better reception).

Also Les you mentioned posting in "Tech Help" to satandpcguy. I can't see a way to post to him directly so do I just include it in the body of the post and hope that he picks it up? (Sorry if this is a compltelty numpty question!). Thanks!

Darren: A few Panasonic devices can have problems with the BBC's use of a 23000 symbol rate, as most that dont have 23000 shown as a manual entry option usually have it come up with a factory reset auto-scan.

You should have a look at the manual tuning option and enter the details below, these being for the BBC HD service.

Frequency : 10847
H/V : Vertical
S/R : 23000
Modulation : QPSK
FEC : 8/9.
