摘要： An interactive television system displays a television program having an associated channel. The system also displays an interactive television mode indicator if the displayed television program supports an interactive television mode. The interactive television mode is activated in response to a request from a viewer of the television program to activate the interactive television mode. The system updates a channel status list to indicate that the television program is being viewed in the interactive television mode. The system is also able to handle requests for activating an online television mode. When changing channels, the channel status list is used to restore a previously activated interactive television mode or online television mode for a particular television channel. Two different indicators may be displayed to indicate whether the television program supports an interactive television mode and/or an online television mode.
