Audio/video programming content is made available to a receiver from a
content provider, and meta data is made available to the receiver from a
meta data provider. The meta data corresponds to the programming content,
and identifies, for each of multiple portions of the programming content,
an indicator of a likelihood that the portion is an exciting portion of
the content. In one implementation, the meta data includes probabilities
that segments of a baseball program are exciting, and is generated by
analyzing the audio data of the baseball program for both excited speech
and baseball hits. The meta data can then be used to generate a summary
for the baseball program.
