Sony Bravia 703EX

I'm experiencing zooming on STVHD(51) as it constantly switches between 1080i and 1080p. Also have this on BBCHD channel(54)
Very annoying!!
Any info??

Adrian Tobin: Your set should not "zoom" when switching between 1080i and 1080p.

You might need to do a "software upgrade" on your set, which you can get from here http://support.sony-europ…X703 .

Adrian, I saw this answered on another site. The broadcasters switch dynamically between 1080i and 1080p to maximise picture quality. Your TV has different picture settings for each of these modes. You need to alter the zoom setting for each mode so they match :)

Black Hill COM5 & COM6 have now changed to 3/4 FEC and are now 27Mb/s.

David: I think the resultant bitrate is actually still 28Mb/s due to changes of the guard interval to compensate for the change to FEC. I will get around to making the necessary code changes to show the overridges above at some point later this week.

Hi. We get intermittent interference on Mux2 channels, but no others. This lasts up to an hour, making the channels unwatchable, and happens at random times during the day. It is not associated with any of our electrical goods being on or off. Aerial is on the roof and we have a booster in the attic. Blackhill is our transmitter. Any thoughts? If your suggestion is that it is interference from external sources, then bring back analogue!

Briantist: Changing the guard interval would not itself improve reception directly (except in rare cases of strong distant echoes, which are unlikely; 7.5km is plenty of distance to prevent this problem). It would improve only if the intent was to synchronize transmissions with another transmitter, in which case the overlap area would have constructive, rather than destructive, interference. It all hinges on the timing.

The nearest candidate using the same frequencies will be Chatton, when it switches over at the end of next year. For that reason, I doubt that it is to do with improving coverage.

Others are certainly reporting that the guard interval has not changed and therefore capacity has increased. The larger capacity is for the moment just carrying more null packets.

On its own, this change will reduce coverage slightly.

The retrofit is due to complete, at least for ArqB, on 23 November (Selkirk, and Tacolneston DSO 2), so we should know more then.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
