Zapping
Let the user to step through the available services and select the required service.
Zapping also includes the actual steps for tuning to another channel. It performs
activities such as blanking audio and video, setting the right frequency, retrieving
the actual channel content from the PSI/SI tables (if a digital channel is selected). It
also enables selection of the right virtual channel to be decoded (depending on the
language setting, for example) and also unblinking of video/audio. The selector has
to dynamically react to any changes in the active transport stream – such as a
change in the rating of the currently running virtual channel from the transport
stream or even the actual disappearance of the selected virtual channel. The
underlying software therefore notifies it of any such changes. (DTV only)
