| 1. An interactive television (ITV) system comprising:
a first-input for receiving a first data stream for a particular television program;
a second input for receiving a second data stream for the particular television program, the first data stream having a higher
priority than the second data stream; and
a processing unit coupled to the first input and the second input, characterized in that the processing unit creates a gap
in the first data stream for inserting at least a portion of data carried by the second data stream, the gap being selected
in a location in the first data stream so as to allow the data carried by the second stream to be effectively displayed without
disrupting display of data carried by the first data stream.
