Automatic updating

Digital tuners, like computers, have their own software programmes. This means set top boxes, digital TV recorders and iDTVs can be re-programmed by having updates automatically broadcast to them - as long as they are left in standby. New services and other improvements are added in this way.

So long as you leave your box or iDTV in standby then it should automatically pick up any updates that may be broadcast.

Remember the current 'digital tick' means a box will carry on working through switchover but does not guarantee it will be updated with future improvements. Also, if you are looking to buy now, also bear in mind some manufacturers might drop older existing products and replace them with new models with planned improvements.
