    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.

    摘要翻译： 交互式电视系统显示具有相关频道的电视节目。 如果显示的电视节目支持交互式电视模式，系统还显示交互式电视模式指示符。 响应于来自电视节目的观众的请求激活交互式电视模式，交互式电视模式被激活。 系统更新频道状态列表以指示正在以交互式电视模式观看电视节目。 该系统还能够处理激活在线电视模式的请求。 当改变频道时，频道状态列表用于恢复以前激活的特定电视频道的交互式电视模式或在线电视模式。 可以显示两个不同的指示符，以指示电视节目是否支持交互式电视模式和/或在线电视模式。

Two different indicators may be displayed to indicate whether the television program supports an interactive television mode and/or an online television mode.

    摘要： A broadcast signal is received that includes a data identifier that identifies data associated with the broadcast signal. The broadcast signal also includes the data associated with the broadcast signal encoded in the broadcast signal. The data associated with the broadcast signal includes an indicator to ignore the data identifier contained in the broadcast signal. The system decodes the data encoded in the broadcast signal while ignoring the data identifier contained in the broadcast signal. The indicator to ignore the data identifier contained in the broadcast signal may include an associated time period during which the data identifier should be ignored. The data identifier is broadcast in scan line twenty-one of a broadcast image. The data associated with the broadcast signal is encoded in vertical blanking interval lines of a broadcast image.
