In an interactive broadcasting system, television programming may be
broadcast with interleaved web content information. The progress in
broadcasting the web content information over one or more transports and
over one or more channels within those transports, may be monitored to
provide a time based indication of what content has been broadcast. In
one embodiment, markers may be inserted into the data transmission flow
and a method may be utilized to associate a handle with a particular
marker. A method may be called which obtains the handle and another
method may be utilized to invoke the handle to obtain current information
about broadcast transmissions. This information may be used within a
broadcast encoder or may be provided to a content provider, for example,
through a log-in server.
