Live-Net TV Network: 2 – Opening 1987

In the first part of this look at Live-Net I showed the lead-up to the opening of the system with a visit by Princess Anne to the Science for Industry exhibition the previous year. But now, we’ll see what followed on from that. Once the demonstrations were over and the Science for Industry Exhibition closed, it was time to start using the system for real. Many tests and trials took place and slowly teaching started to make use of the system. You’ll see some of that teaching in the video at the end of this particular blog entry. Even though Princess Anne had already seen Live-Net in action it was always planned that she would officially declare it open at some point. This took place from Senate House in central London and linked out to all those sites currently connected. The photo shows the Royal Party along with Richard Beckwith looking at the monitors that showed the Live-Net sites (Imperial is in the centre). On the 28 May 1987 the system was buzzing with images going backwards and forwards to Senate House. BT were standing by as part of the demonstration and to ensure 100% connectivity! The person given the overall responsibility for the connection and use of Live-Net at Imperial College was Professor Ernie Freeman (1937-2022) then in Electrical Engineering.

Ernie handed over all of the technical tasks to me and that involved the planning of any ‘studio’, purchase of equipment and so on. Initially we simply used the TV Studio as this had cameras, sound and monitors. Later we produced a separate studio solely for Live-Net. As I had been involved from the very start, I was asked to participate in the opening ceremony and can be seen on the right hand side (all dressed up for the occasion) with a camera control box hidden behind some flowers! The background board was a left-over from the Science for Industry exhibition the previous year. There was one final royal visit to see Live-Net, but this time it was not Princess Anne.

The IEEE were meeting at Imperial College along with their President the Duke of Kent. Ernie Freeman was asked to show off Live-Net as it was an interesting and new use of fibre optics for university teaching. Once more we used the TV Studio for the event and Ernie Freeman is seen with the Duke of Kent in this off screen photo of the actual transmission. Of course there was interest not only in how it would be used for teaching and the styles being adopted for this in teaching habits, but also in the technology. This was left to me to explain (the best I could) and to show the BT equipment being used.

There was also great interest in the central switching system and computer control. This was achieved with a terminal connected directly to the BT equipment rack and then via the fibre optic cable to Senate House. That’s me talking to the Duke and explaining our equipment rack and how the images were switched around the network.

In 1990 I made a promotional video for Live-Net. We shot at most of the connections to show how staff and students used the system. We also interviewed people to see what they thought of the technology and its usefulness. In the same year, BT attempted a sales campaign for the system, quoting its ‘ease of use and flexibility’. I’ve scanned in the only remaining brochure that featured the system and if you click on the picture it will go full screen to enable it to be read. The suggested ‘control’ box was a faked prototype and never existed for real.  The room full of participants was in Senate House (shown in the picture top left of the page). Live-Net eventually fell foul of the technology which was moving forward very rapidly. The system was analogue and BT was already changing into digital for most applications. The cost to convert Live-Net was considered too high for most of the participants of the system and Imperial College was one of the first to drop out. A slow decline followed and the Internet simply took its place.

Live-Net TV Network: 1 – Pre-Opening 1986

In 1985 a proposal to install an experimental cable TV network between some of the schools of the University of London came to fruition. British Telecom had pioneered the use of fibre optics with the installation of Westminster Cable Television in London. The fibre cables linked to central street boxes that then fed into homes on coaxial cables (Switched Star Cable TV system). This enables users to select what they wanted and the resulting signal was then sent back to the street cabinet and then to the home.

Moving this technology one step further on, BT proposed a system where the fibre came direct to a cabinet located at some of the Universities in London (UCL, Imperial, Kings, QMW, RHBNC and the ULAVC at Senate House). The resulting system was called Live-Net and consisted of a bundle of fibres providing 4 in and 4 out channels at near broadcast quality.  It had been decided to locate the central switch for the whole system at the University of London’s Audio Visual Centre located at Senate House. This would also act as an additional transmission point for establishments around that area, for example Birkbeck College.

Princess Anne arrives at Science for Industry Exhibitio

The installation required the actual pulling of a cable containing these fibres through ducting in London streets to the various locations. I recall the day that the cable was brought into Imperial and then through building ‘risers’ up to the TV Studio which was then located in Electrical Engineering on Level 2. A rack then contained all of the electronics which linked to these cables. The initial major job for BT was the termination of these cables to provide a connection to the optical hub. We were aware that the central switch was already in operation and the link to the Audio Visual Centre established. Imperial was to be the first connection after this to coincide with the upcoming University of London “Science for Industry” Exhibition to be opened by Princess Anne, Chancellor of the University of London on 13th October 1986. If the Imperial link could not be established then the showing of Live-Net at that Exhibition would not take place. The short video extract below is all that remains of the first moving images sent through the fibre network a few months before the exhibition. Moments after the BT engineer terminated the fibre cable, images came through from Central London. Ray Bradley was then Chief Engineer at the Audio Visual Centre located at Senate House. In the video (seen here for the first time), he takes a phone call from me to confirm establishment of the connection by BT. We had no sound at first so we reverted to using the phone!

 

The installation was indeed completed and the first public showing of the system took place during the University of London’s Science for Industry exhibition held at Imperial College between 13th-17th October. During that week the TV Studio relayed images from the Live-Net system into the Junior Common Room where screens were setup to display the channels available. Princess Anne saw Live-Net for the first time on 13 October 1986. The video below has never been seen before and I have edited it into a sequence for this blog. I also shot footage of the exhibition and I’ll include that in another entry soon.

Participants were welcomed into the TV Studio to link and talk to remote locations within the University of London. The photo shows two things, firstly on the left the incoming image from the ULAVC at Senate House, (the Studio image is over on the right) and secondly I am sitting at a terminal connected to the central switch. I was able to switch the signals going to the exhibition and also ‘to and from’ Imperial in general – all of this using a BBC Micro Computer too!

There was another event to launch Live-Net that I’ve just remembered. This time BT gathered all of those connected with the project together and did it in style. We all met at the top of the BT Tower in London in, what was, the revolving restaurant. And I have this feeing at the back of my mind that this was the signing of the documents between the University of London and BT. If that was the case, then all of that preceded the installation of the actual equipment and cabling, but I simply can’t remember now! I don’t recall any photos being taken either, which is a shame.

In the second and final part we’ll look at the royal opening and a special visit by another member of the royal family!

e-MasterClass 2001

On the 19th June 2001 Sir Richard Sykes, then Rector of Imperial College, launched the first e-MasterClass with a broadcast to distinguished guests from government and other institutions in Britain, Australia and Thailand. The launch was preceded with the statement “Topical debate between masters at the cutting edge of scientific research and peer group scientists and industrialists around the world will be launched next month in what is believed to be the first e-MasterClass of its kind”. This first 40-minute presentation about healthcare policy was chaired by Chris Toumazou and was held in the video conferencing suite, which at the time was located next to the TV Studio on the level 2 walkway.

The technology used to link the various locations was Video Conferencing using ISDN2. The equipment allowed the ‘multipointing’ of the three sites into a split screen which meant that participants could all see and hear other with very little time delay. Images were viewed on 50 inch Plasma screens, something back then that was both new and expensive.

Press release information following the second e-MasterClass announced “Professor Ara Darzi impressed participants at the University of New South Wales, Australia, with a presentation entitled Look no hands — an exploration in cybersurgery which encapsulated his team’s dynamic new approach to micro-surgery and robotics and set out his vision for the future of surgery”.

Professor David Phillips presentation

 

 

Live Internet streaming came later

The e-MasterClass, as originally intended, carried on for just over a year when they turned in Schools e-MasterClass. These potentially had a wider audience and continued Imperial’s links with schools in general. On the 10 July 2002 David Phillips from Imperial and colleague Steven Bown from UCL gave “A little light relief”. Again a pre-event announcement said “A Little Light Relief”, will provide an interactive overview of the subject that will give Year 9, 10 and 11 students the opportunity to engage with scientific developments” In the recording of the event (below) you will notice that the chairman is Noel Edmonds. He owned the Video Meeting Company which supplied Imperial with the Video Conferencing equipment. As publicity, he was persuaded to take part.

These initial events were successful. But the schools were all connecting using ISDN2 which few other schools had available. It was obvious we needed to revert to using the Internet which all schools did have available. However, what no one had told us at the time was that almost none of the schools could Video Conference connect to IP addresses outside of their own grid (for security reasons). So, we started to stream events in parallel on the Web. Again, schools could not connect as they were limited to a strict list of URL’s. None of the schools were prepared to change this list and slowly over just a few years the whole e-MasterClass just stopped!

In 2001 we made a promotional video to show the potential of the original  e-MasterClass. The video is largely based on Richard Sykes presentation in June of that year. It includes shots showing what the remote end of the links were seeing. These days the technology allows people to link from their computers and this gives the possibility to link at night, but to do so from your home not from a University room. There is the obvious fact that very long distance ‘live’ teaching, such as the original e-MasterClass idea, is totally governed by TIME. A time difference between London and Sydney of 11 hours makes it very difficult to bring together people who (at 10pm at night in Sydney) would rather be at home, than watching academics talking in London. Time-Difference was one of the reasons for the downfall of the original e-MasterClass. But, what we did worked and maybe just proved a point that Imperial can do such things. I had fun with these events and the tension of things going wrong was always there. The e-MasterClass was, perhaps, a little too early in terms of the technology available at its start in 2001 and could be superseded by things like Skype available on your computer at work or home.

Note that the web/email links on the video will no longer work!

Centenary Ceremony: 9 July 2007

The Centenary of the foundation of the College was celebrated on 9 July 2007 with a ceremony in the presence of Her Majesty The Queen and His Royal Highness The Duke of Edinburgh. The Queen and Duke also opened the College’s new Institute of Biomedical Engineering before taking part in an honorary graduation ceremony that saw the first ever Imperial degrees awarded to five distinguished figures, including His Royal Highness The Duke of Edinburgh.

The ceremony followed the bestowal of a Royal Charter by Her Majesty The Queen that declares the College an independent university in its own right after its withdrawal from the University of London.

The visit cemented a long-standing relationship between the UK’s Royal Family and Imperial. The College stands on land purchased with the profits of Prince Albert’s Great Exhibition of 1851 in fulfilment of his vision for a centre of science and culture in South Kensington.

The event was recorded for posterity and at the same time relayed live via web links to all parts of Imperial College, whether on the South Kensington Campus or not. Three cameras covered the ceremony from different angles and I mixed the event live at the time. What you see here is the full unedited live coverage version and please note that unlike BBC broadcasts of such events, there is no added commentary. The ceremony took place in the College’s main entrance hall with special staging having been built for the occasion. Rector at the time was Sir Richard Sykes. The recording runs for just over 30 minutes.

Christmas Caper – 1988

24 years ago in December 1988 Imperial College held the first event aimed at children to introduce them to science. The event was Christmas Caper and departments and sections throughout Imperial College came together to create a ‘wonderland’ of science for the kids. Not all the things were specifically science, face-painting being one of them. It was held during the afternoon and staff were encouraged to bring their own children along. It took place in what was the lower refectory in Sherfield Building. The event was masterminded by Claire Ash, the then Rectors wife.

The Archbishop of Canterbury 1969

In February 1969 the then Archbishop of Canterbury Dr Michael Ramsey made a visit to Imperial College. From the 3rd to 6th of February he had several engagements at Imperial. But the most important to us was a special televised event at 12noon on Tuesday 3rd when Sinclair Goodlad hosted “Face to Face” in the fledgling TV Studio, then located on level 3 of Electrical Engineering. The programme was relayed live to many locations as well as recorded onto videotape. As you will already suspect, that videotape was lost a long time ago.

What we have left is one black and white photograph taken at the time. But, I did happen to have my 8mm cine camera loaded with film and had it with me on the day. The fragment of 24 seconds of colour film is therefore all that remains of this important day. I did manage to find a reference to his visit in the archive collection of Felix, the Imperial College student union newspaper. The file will download as a PDF and look at the top of page 3 for the article.

Commemoration Day

As we celebrate yet another Commemoration Day at the Royal Albert Hall I thought the time was right to bring  you the few recordings we have from earlier years. At the end, I’ll mention technical challenges involved with the transfer of the first two recordings onto modern formats.

Although you’ll find this first recording elsewhere I’ll include it again for completeness.
The October Commemoration Day graduation ceremonies recall the visit made to the College by King George 6th and Queen Elizabeth in 1945, on the centenary of the foundation of the Royal College of Chemistry, Imperial College’s oldest forerunner. King George said: “You students here assembled – men and women who soon will be going out from the Imperial College to your work in the world – have not only an opportunity but also a responsibility greater than men of science have known before. To you, I say: Regard your knowledge and your skill always in the light of a trust for the benefit of humanity, and thereby ensure, so far as in you lies, that science may never be put to uses which offend the higher conscience of mankind.”
For those unfamiliar with King George 6th, he battled throughout his life with a nervous stammer and his attempts to overcome this during the speech are obvious with long pauses between sentences.

 

Karl Compton 1952

From 1945 we jump to 1952 and a recording that, so far, I have no idea exactly why it was made. It features Karl Compton who was a prominent American physicist and president of the Massachusetts Institute of Technology (MIT) from 1930 to 1948. In 1948 he resigned his post as President of MIT and was elected president of the MIT Corporation. He held that position until his death on June 22, 1954, some two years after this sound recording was made. Compton was awarded a fellowship in 1949 but was unable to attend, but in 1952 he was special visitor and collected it then. Interesting references are made to key players in college life at that time: Chairman, Viscount Falmouth; Rector, Sir Roderic Hill along with Sir Henry Tizard, Sir Richard Southwell and Sir George Thomson. There is only part of the introduction by Viscount Falmouth to Karl Compton on the original tape, so it will sound a bit truncated. At the end, Compton reads greetings to the Imperial community from the President and also the Chairman of MIT and the American national anthem is played. Could this be why it was recorded?

Finally, we have something visual in the form of a 16mm colour film shot in 1973. Robert W Sarnoff was President of RCA (Radio Corporation of America). He was the eldest son of broadcasting mogul Brig. Gen. David Sarnoff, he followed in his father’s professional footsteps throughout his career at NBC and RCA. The citation for Sarnoff indicates that he was the benefactor of the Imperial College Haldane Music Library. A year later in 1974 Sarnoff married Metropolitan Opera diva Anna Moffo, so maybe opera was his interest as well as being the music library benefactor? As I understand it, Sarnoff  himself paid for large parts of the 1973 Commemoration Day ceremony to be filmed in colour and with sound. Lord Flowers was Rector at the time and is seen in this current extract. This is the earliest moving picture record the college has of one of its ceremonies and it’s thanks to Robert Sarnoff that this happened. One of the greatest achievements by RCA and Sarnoff in particular was the development and introduction of colour TV in the USA. He was the first person to be officially televised in colour at the dedication ceremony of NBC’s new Washington, D.C. facilities on May 22, 1958. For those interested, you can see an amazing videotape that has been rediscovered of this 1958 event. The program represents the earliest known colour recording discovered to date.

The transfer process
The transfer process

The first two sound recordings could have been lost for ever had we not transferred them onto modern formats. The 1945 recording of  King George 6th is held on 78rpm shellac discs which are very delicate and will break if dropped. I had these transferred by the National Sound Archive a few years ago. Although, in theory it’s easy to copy these discs, using the correct pick-up weight and stylus is essential. Using a modern LP stylus will simply “bottom’ into the disc’s groove and produce more scratch and crackle then actual sound and can damage it too.
The second recording IS interesting. I discovered that the recording tape used paper as the backing, rather than a form of plastic and its manufacture probably dates from the 1940’s. The oxide was also very basic and looked more like gunpowder than anything you could record sound on! Transferring the tape was also a challenge as I had to run the tape very slowly because it was sticking to itself like a reel of sticky parcel tape. A lot of background noise will he heard and I’m still amazed I managed to get anything off of it anyway.

I hope you have enjoyed listening to our recordings of Commemoration Days from the past….unless YOU have something we don’t know about?

Events: St Mary’s Merger Ceremony 1988

On the 19th October 1988 the beginning of the mergers with the medical schools started. This was the merger between Imperial College of Science and Technology and St Mary’s Hospital Medical School, located just north of Kensington Gardens and Hyde Park at Paddington. The end result of the mergers was the formation of the Faculty of Medicine.

St Mary's campus
St Mary’s main entrance arch

To my knowledge this is only the second time that the college’s Great Hall has played host to a royal event. The first of these was the opening of the building (then called College Block and subsequently Sherfield Building) and the hall itself by HM the Queen in 1969. The hall was packed as you would imagine and that didn’t leave all that much room for the two cameras and tripods we had proposed for the live recording. We were also limited in terms of man-power so my colleague Chris Roberts operated the main camera whilst I located the second camera next to where I had the vision mixer and recorders. This meant that I could not only cut between the cameras, but also operate the second camera to change the shots slightly. What I could not cope with was the fact than when people stood up, they almost blocked the shots from the camera next to me.

The ceremony starts with the fanfare “St Mary’s”. There are then several musical interludes during which you’ll see a very young Richard Dickins and these 22 years later I must apologise to Richard because we got the spelling of his name wrong on our end credits. But, it’s a wonderful record of music from the college symphony orchestra playing Walton’s ‘Crown Imperial’. Also the late Eric Brown conducts the college choir with music from Carmina Burana.  And finally in terms of music you’ll hear the electronic organ that’s located within the hall. Princess Anne, (The Princess Royal) as Chancellor of the University of London presented the Chairman of the Governing Body (Sir Henry Fisher) with a specially bound copy of the Imperial College Act and its revised Charter. The Imperial College Rector at the time was Professor (later Sir) Eric Ash.

As always, I’ve had to tweak the image on the video to make it look at bit better. Technology has advanced a lot since this was recorded and the lighting levels required to get good images is a lot lower these days. The Great Hall have never been fantastic for shooting video unless extra light is thrown at the stage area and that then leaves the audience rather dark, whilst the wood panels around the hall make a very warm image when light bounces off it. The whole video is around 45 minutes in duration.

Rectors: Lord Brian Flowers

Mary and Brian Flowers
Mary and Brian Flowers

Brian Flowers (1924-2010) became Rector in succession to Lord Penney in 1973. Then Sir Brian, he quickly became popular and approachable with staff and students alike. The now famous ‘beer and bangers’ parties held by him and Lady Mary Flowers (1921-2016) were hosted in their flat at the Norman Shaw designed building at 170 Queens Gate. This gave many people the opportunity to meet both of them and in particular to gain access to one of the most wonderful buildings owned by Imperial College. Five years after he became Rector, I shot a video with the student TV service STOIC, this was the first time a video had been shot in 170 and in particular up in the Rector’s flat (a photo taken during this event is at the bottom of this entry with me in silhouette on the extreme left hand side). Please click on MORE to continue reading this post. (more…)

Queen’s Tower

One day, back in 1988, someone asked me the question “Could you do live TV from the top of the Queen’s Tower?”. Up to that point I can’t say I’d really thought about it much, but it was an interesting question nevertheless. But we’ll come back to that in a while.

Queen's Tower
The Queen’s Tower

Anyone who has visited the South Kensington campus would have seen the tower at some point. It’s some 287 feet tall and has some 324 steps up to the dome area. One of the main times the tower is noticed is when the bells are rung and these are as follows:

Queen’s Accession: 6 February
Queen’s Birthday: 21 April
Queen’s Coronation: 2 June
Duke of Edinburgh’s Birthday: 10 June
The Princess Royal’s Birthday: 15 August
Prince of Wales’ Birthday: 14 November
Queen’s Wedding Day: 20 November
and of course both PG Awards and Commemoration Days each year.

It was on 20 November 1997 that we recorded the bell ringers for the first time. This was to mark the Queen’s 50th wedding anniversary and a special ring was performed. Carrying cameras and recorders up the tower is not an easy tasks as the spiral staircase was never designed for this. But we made it and proceeded to capture the event. What no-one had bothered to tell us was that the tower does move a bit when the bells are being run. First one way and then the other depending on which set of bells are being run at the time. Sets of bells are hung in different ways; one set ‘left to right’ and the other set ‘top to bottom’. This therefore gives a strange effect of movement swaying one way, then the other. The combined result when all the bells are being run is a very odd circular motion. Although I’ve recorded the actual bells with hanging a mic in the bell chamber, I’ve never captured them on video…but someone else has! If you go to this YouTube video you’ll see the horrifying sight of the whole set of bells ringing below the camera lens. I can’t say that it looks very safe up there and the volume of sound must be rather high too.

Another great reason to remember the Queen’s Tower were the (now long gone) performances in May each year of the 1812 overture. These were accompanied by live explosions provided by DramSoc and the bells in the tower were rung. I’m not certain why this event stopped, maybe it was the British weather! Anyway, in May 1979 I recorded the event in colour, the same summer that we actually got our colour equipment.

And so, back to the start and that question about live TV from the top of the tower. Back in 1988 during preparations for one of the first Alumni weekends the idea came about to broadcast the weather one morning from the Queen’s Tower. Francis Wilson was, at the time, forecasting the weather for the BBC Breakfast programme. Because he’s an Alumni of Imperial he was asked if he would do it and of course he agreed.

Vision, Sound and Videotape equipment set-up in the tower

We did weather from the tower twice and you’ll notice the reference to hearing the sound this time around. In fact we were some minutes away from the live link and someone managed to move the equipment providing the ‘line of sight’ link. You can see some photos I took at the time and two of these show the amount of equipment we had to carry up the tower. One is showing the equipment set up for controlling sound and vision and the other is showing the infra-red line of sight link from the tower down to the area now known as the “tower rooms”. One thing we were lucky to have was mains power and down in the bell ringing chamber, a telephone line.

Infra-Red downlink from tower to ground floor

 

 

The recording you’re now able to see of the event was made down on the ground floor where the TV monitors were located. I’m still amazed it actually worked and the quality was pretty good too. The infra-red link had to be lined up with a telescope that had a cross-hair to align with the receiver, also set up on a tripod down on the ground. All you then had to do was to feed video and audio into the unit and you were in business. The only problem, as we discovered, was not knowing IF those down below could actually see and hear anything once you had started the event.

My colleague at the time Chris Roberts is seen operating the camera whilst I was pressing the buttons, mixing sound and running-in the videotaped sequences we were given from our colleagues in Physics. It was good fun, the Alumni visiting seemed to enjoy it, but it was very hard work indeed….there are a lot of steps up to the top and I was a lot younger then too!

The day before the event we had already taken most of the equipment up the tower and tried out the link. Those down on the ground floor were somewhat surprised to see this caption on the TV screens. It was broadcast from the tower and was announcing the forthcoming live link the following morning.
