Live-Net TV Network: 2 – Opening 1987

Monday, April 1st, 2013

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 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. (more…)

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

Friday, March 1st, 2013

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. (more…)

e-MasterClass 2001

Friday, February 1st, 2013

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”.

Videos for Schools on YouTube

Thursday, January 17th, 2013

You can now find all of the remaining videos that were made for schools on the Imperial YouTube Channel. They are located in the Archive section along with other gems that are being added as time permits. I’ve included two of them in this blog, but do go to YouTube to be able to see them all. One video that stands out as an example of science and technology is the one with Denis Smith on Water Power and the Industrial Revolution. We made the video in many parts of the UK at various (then) working Watermills, Pumping Stations and so on and it was a real joy to make too.

The two pictures show Dr Denis Smith at (above) Abbeydale Industrial Hamlet in Sheffield and (below) and at a lock on the Kennet and Avon Canal.

UPDATE April 2018: I’ve only just received the sad news that, after a long illness, Denis died last November.

Here then is that video on Water Power and the Industrial Revolution.

The last video we made for schools was on the subject of the weather. This video was presented and written by Francis Wilson, and ex Imperial student and who, at the time, was presenting the BBC Breakfast show weather each day. Here is Weather on the Move.

Videos for Schools

Tuesday, January 1st, 2013

Back in early 1982 a tenuous link with the History of Science and Technology division brought forth an idea to make a series of videos designed for schools. Colleague Dr  Kathy (Kathleen) Burk had links with a publishing company based in Wiltshire. They produced mainly audiotapes on history and some on music. They had started to venture into videos but with limited success from both the technical and production viewpoint (they had no production facilities of their own).

It was therefore suggested that because of the Imperial College connection with the company there might be some merits in linking together our combined skills: History; Publications & Marketing and Video Production. So a compromise was reached over the production of 8 videos between 1982 to 1990.

In this entry I’ll be showing you two videos made between 1982 and 1984. Simon Schaffer has become a well known presenter on broadcast television with series such as the 2004 “Light Fantastic” shown on BBC TV. But back in 1982 he had only recently joined Imperial College in the History of Science and Technology division. Kathy Burk asked him to consider making one of the videos for schools and so we produced the 1982 video called Science and the English Enlightenment. (more…)

Promotion: 3 – The Chemistry Department

Monday, November 5th, 2012

In “Promotion: 1” (March 2010), I mentioned the Civil Engineering and Chemistry Departments. In June 1981 I was asked to take on the task of making a promotional video for the Chemistry Department.

The Chemistry Building in March 2002

This was intended to promote all aspects of what the department did and to assist in the recruitment of new students. I also recall it being shown at Open Days which seemed obvious . Two members of the staff were appointed as ‘producers’ so most of the content and the wording of the voiceovers was decided for me. Looking back at the video over 30 years later it has too much in it. The history section seems unnecessary and there’s too much detail in the various elements featured. It runs for nearly 20 mins which is about two thirds too long in todays modern YouTube video world. Leave them wanting more is the theory, not wanting to leave the room as soon as the video has eventually finished! This was one of two videos made for the department, the second being made four years later in July 1985. It’s worth noting that both of these videos were made using our original colour camera. It needed massive amounts of light (as mentioned in the Library video) and suffered ‘smearing’ on highlights, the colour itself was none too brilliant either! (more…)

Life Science Library 1979

Life Sciences Library video August 1979

Shooting the video’s  introduction

The first programme we made in colour was a guide to the Life Science Library. That was 33 years ago in August 1979 and colour was so new that we didn’t even have a colour logo caption at the start, in fact it’s our original black and white logo. Interestingly, the video is a great snapshot of what libraries looked like and how they operated at that time. Card indexes were still the norm with microfiche readers being a new addition. There is also mention of having a literature ‘computer search’ carried out at a cost of around £5, a cost which was probably considered high at that time and would have been carried out by a librarian for you. One of the great advantages of us moving into colour was the fact that we were able to edit. Until then it was possible, but difficult and in black and white too. The video required a lot of different shots, like close-ups of index cards, so editing was an essential part of the production, in fact, without editing this programme could not have been made.

Life Sciences Library video August 1979

Lots of lighting was needed inside

Because we were going to cause some disruption in the library, where possible, we shot in the evening, or at least after 5pm. As you can see from the photo on the left, we also needed light..lots of it too. Our early colour camera was happy with external situations, but inside it required rather a lot of light to get good images. The library, at that time, was rather lower in light levels compared to today and there was no way we could cope without adding some extra lighting. Our biggest problem was finding mains sockets anywhere near the rows of book shelves. You tend not to need mains sockets when looking for books! Like most of our videos, we sometimes needed (and still do need) ‘rent a crowd’, so see if you can spot me appearing twice in the video. Also note a major change to the feel of the South Ken campus from when this was shot in 1979. See how empty it is soon after 6pm when the external footage was shot.

The video style is a bit 1970’s, mainly because that’s when it was made. I can’t recall under what circumstances the video was due to be seen, but I think it was designed to be viewed in the room that had been designated for watching videos. This was one of the small rooms called a Carrel around the edge of the library in which a monitor and video recorder had been installed. You’ll hear reference to these Carrels in the video. Listen out too for the mention of photocopies, there were only two in the whole library at that time. Now there are machines on every floor!

The presenter of the video is Mark Caldwell, an former STOIC chairman from the mid 1970’s. Mark is now based in Germany, working for the world radio division of Deutsche Welle. From time to time you can hear him presenting items like this one on the Planck and Herschel space telescopes.
