I spent an interesting day last week in Birmingham (or Brum as it is affectionately known) at a workshop on Business Process Modelling given by Balbir Barn of Thames Valley University. Birmingham has certainly changed since my youth there and the workshop was held in the completely redeveloped Brindley Place area of the city. This used to be a decaying network of stinking canals, collapsing Victorian warehouses and rat-infested walkways. It is now home to flash hotels, bars, offices and a series of conference venues including Austin Court, where the workshop took place. Lunch included chocolate covered strawberries which were extremely tasty, although probably ethically dubious given that this is March.
The workshop itself covered Business Process Modelling Notation (BPMN) a diagrammatic notation for representing workflows in the business environment. This probably sounds fairly dull, but it is quite interesting in that it was aimed at higher education and is a sign that universities are becoming more aware of the methods used in the commercial sector. Towards the end of the day, one subject of debate was the likely uptake and impact of using such workflow tools in higher education settings. It can certainly be argued that there are parts of the university system that are akin to the bureaucratic functions of a business (HR, payroll, student registration, course validation). But what of more non-traditional areas like library repositories or e-learning systems? Delegates were certainly interested in debating the potential return-on-investment for groups of developers within the education community who have spent time learning and mastering these kinds of workflow tools.
Will Freeview be able to provide High Definition TV to the public?
March 23, 2007Wednesday was budget day. Thankfully lunch was not taxed, but one little-noticed item could cause serious debate amongst technology types.
Digital TV delivered by the FreeView system makes use of a portion of the radio spectrum. With the switchover from analogue to digital TV there is an opportunity to re-jig the way the radio spectrum is used and, in the process, release some spare capacity. This spare spectrum is known in technology circles as the ‘digital dividend’.
So why is this important? Well, buried on page 151 of the Budget Report, the Government notes that, through its agency Ofcom, it is consulting on a proposal that the “spectrum released by switchover should be auctioned on an open basis during 2008-9”.
Herein lies the rub. Note the word ‘open’ in the Budget report. The Government is suggesting that this ‘digital dividend’ could be auctioned off in a process similar to the radio spectrum auction that took place a few years ago, when the Government made billions auctioning spectrum to phone companies for 3G mobile phone capacity. Yet it is this ‘spare’ capacity that is partly needed if Freeview is going to be able to deliver High Definition TV as a free-to-view service.
Such an auction might end up with prices that no public sector broadcaster could compete with and therefore effectively freeze out Freeview from the next generation of spectrum capacity. This could be a problem for the millions of people, who, anticipating the great switchover, have invested in a nice, shiny, new HD-ready TV. If an open sell-off happens, there’s a good chance that they won’t be able to get HD TV pictures over free-to-view services.
