[Sursound] Me again - on the H/HJ hunt
Hi again guys I'm really sorry for the continued questions regarding thwe same subject, but i'm having problems in finding where else where people know anything factual about the BBC's matrix H HJ Quad experiments form 1977 1978 So, here's the issue i now have. I've been sent 4 tapes of BBC quad broadcasts, and the person who sent them says they are in HJ. Does anyone know when the BBC switched from H to HJ? Since successfully finished the SQ QS project, it's time i dealt with H/HJ once and for all. Anyone here remeber anything? Richard -- next part -- An HTML attachment was scrubbed...

Re: [Sursound] Me again - on the H/HJ hunt
Yes'ive seen the BBC document, but the IBA ones new to me. I know the BBC did broadcast some of the Proms in either H or HJ, it's a real shame there's nobody I could contact at the BBC who might have more info. It's another thing that needs archiving, or it'll be lost forever Richard Richard wrote: Anyone here remeber anything?

I need to dig out the CD of one of the Proms. That year the BBC transmitted at least a part of the concert series in surround. Now - was that H-Matrix or what. Wait...

Re: [Sursound] Me again - on the H/HJ hunt
Hi Sorry - can't help with that, but I do remember listening to a couple of the earlier experimental surround broadcasts using 2 discrete frequencies for front and rear - that would have been 1974 or 5 IIRC.

Re: [Sursound] Me again - on the H/HJ hunt
I don't suppose there's a record of what was said. I'm surprised there's no official BBC papers on the matter The odd thing is that one of the recordings I've been sent has Alan Freeman (sadly missed) saying the broadcast is in Matrix H, and this was May 1978. Was he right, or possibly didn't know of the change, or.? An announcement of the shift was published in New Scientist on 5 November 1977. Unfortunately this does not tell you when the BBC switched broadcasting from H to HJ. -- next part -- An HTML attachment was scrubbed...

At least they never transmitted UHJ officially and telling the audience about the encoding wasn't allowed. Maybe it was all experimental and just testing the possible formats? After all, it was the decay era of the actual quad formats. NRDC never got through their suggestion about using UHJ as a quad radio transmission format. Was it the BBC that carried out the test transmissions, or was it the IBA, who had built all the experimental equipment?

Re: [Sursound] Me again - on the H/HJ hunt
The BBC actually listed any programs that were Quad as Stereo/Quad, but I don't remember there being any mention of the system apart from when broadcasts started, and Radio Times did a feature on it Richard wrote: I'm surprised there's no official BBC papers on the matter But was BBC ever using either of the formats officially?

Re: [Sursound] Me again - on the H/HJ hunt
Richard: Curious to have a CD that is encoded in Matrix H after 1982 In that case it's my mistake. There is no indication on the CD about the format. I have just thought that it was H-Matrix. (Thought already more than 20 years ago.) So - could it have been HJ then? Not UHJ, anyway? I remember having seen the vinyl. (I think) it had a mention about the format...

Re: [Sursound] Me again - on the H/HJ hunt
Paul has probably put his finger on it but unfortunately, unless one of the remaining few people who were involved back then have the info, we would probably have to find the original BBC tapes, since they tended to be reasonably well documented. The information might be somewhere in Michael's documentation, but I don't have access to that, and I don't think I have the tapes. Although some did come to me through the John Hayes and Peter Fellgett collections, I don't remember seeing any BBC ones other the Charles + Di wedding ones. Of the people on this group, the one most likely to know is Geoffrey Barton. Otherwise, does anyone know if Bob Harrison (of the BBC, who seemed most closely involved with the Soundfield experiments in the late 70's) is still around and contactable? He might know. On the data for HJ, the November 1977 one seems most likely, as I seem to remember getting a correction to my Integrex decoder to make matrix H into HJ - and we bought the kit as soon as it became available.
