"The changes to the transmissions, which will take place on Wednesday morning, will also mean that 22,000 older digital TV set-top boxes will no longer work.
These are the Daewoo DS608P, the Labgear DTT100, the Triax DVB 2000T, and the Portland DP100. Combined set-top box and video recorders that will not work are the Daewoo SV900 and the Bush IDVCR01.
The changes also mean that some 460,000 households which get their TV channels from a relay transmitter will no longer be able to watch ITV3 and ITV4."
