Abstract

A digital video broadcasting receiver comprising a first input for receiving a first transport stream of data (TS#1) and a second input for receiving a second transport stream of data (TS#2), each transport stream comprising a plurality of packets and each packets having a header including a packet identifier PID. A de-scrambling device (12) receives packets of a transport stream for de-scrambling. A router (20) is arranged to pass packets alternately from the first TS#1 and the second TS#2 transport streams to the de-scrambling device 12 and to pass packets alternately to a first a second output, so restoring the first and second transport streams of data in a descrambled form.
