Abstract
Transmitting data includes grouping the data into one or more packets, constructing a segment of data packets, and transmitting the segment more than once. Control information indicating that the segment is about to commence may be transmitted prior to transmission of the segment. Similarly, control information indicating that the segment has ended may be transmitted after transmission of the segment. The transmission may be performed by superimposing the segment and control information onto a video signal.
