Transmitting streaming media data in overlapping bursts can reduce data
loss when transmitting over radio frequencies to a roving digital
receiver. A digital transmitter transmits streaming media information in
bursts, where each burst of data preferably contains several seconds of
streaming media information. The streaming media information to be
transmitted is grouped into transmission bursts, or packets, each
transmission burst containing several units of media content, or content
units. A content unit is an amount of content that is stored and played
by a digital receiver. Each burst contains a certain amount of
information, such as a certain number of content units, which are the
same as some of those sent in the previous burst. Each burst also
contains new content units, i.e. content units that have not previously
been transmitted. Transmitting overlapping bursts of information allows a
roving receiver to temporarily lose contact with the transmitter, and yet
minimizes the loss of data from the receiver's perspective. The
overlapping nature of the packets makes it more likely that a roving
receiver will receive all, or most, of the content units needed to
continue playing the media presentation without "dead space" or static.
