Abstract

This invention will "surf" or "monitor" a selection of other channels in the background, looking for user entered search words in the closed caption (CC) data of these channels. When a match is found, it automatically brings up the other channel in a Picture in Picture (PIP) window, so that what you are watching is not "blasted away" by the other channel. This invention would have functions for: Entering search word(s), and optionally logical operators (AND, OR, NOT) Entering which channel(s) to monitor CC for these words Activating and deactivating the monitor function Optionally recalling and editing previously saved monitor session(s) In addition, one problem with currently implemented PIP technology is that the viewer only hears the sound from the main TV channel being viewed, and no sound from the PIP channel. Sometimes the information that the viewer wants to monitor in the PIP cannot be determined or understood by picture alone. Consider a newscast where the viewer may be looking for a particular story. In this case the viewer may be watching two newscasts at the same time wanting to catch the first one to broadcast the story, but from a small picture in a PIP of someone reading the news, it's hard to tell what they are talking about. Therefore, this invention also includes an option that will display the CC for the PIP channel on the main screen, where the main screen's CC would normally be shown. This way the content on both channels can be monitored (i.e. sound will be from the main channel, and the CC from the PIP channel). In the case where CC is already active for the main channel, the PIP's CC would normally not activate nor overlay the main channel's CC. Alternatively, the user could choose an option to override the main channel's CC with the PIP's CC. Either way, color can be used to indicate that the CC is from the PIP channel and not from the main channel (e.g. white text for main channel, green text for PIP channel). The color choice could also be a set-up option, and could match the color of the frame around the PIP to further aid the user in associating the text with the PIP.
