摘要： A digital television signal receiver (20) processes a digital television signal and auxiliary information contained in the digital television signal regardless of whether the auxiliary information is analog auxiliary information (36) or digital auxiliary information (34) and produces a television display signal (44) suitable for displaying the processed auxiliary information. In the case of the auxiliary information being closed caption information, the digital television signal receiver extracts and processes digital closed captioning information according to standard EIA-708 or extracts and processes analog closed caption information according to standard EIA-608. The television signal processing receiver thus allows the user the option of selecting a fallback method of obtaining captioning for a digital program signal if the digital program signal does not include digital closed captioning. Thus, if a digital television signal does not include digital closed caption information, the digital television signal receiver automatically processes any analog auxiliary information and provides a television signal having closed caption information suitable for display.
摘要翻译：无论辅助信息是模拟辅助信息（36）还是数字辅助信息（34），数字电视信号接收器（20）处理包含在数字电视信号中的数字电视信号和辅助信息，并产生电视显示信号（44 ）适用于显示已处理的辅助信息。在辅助信息是隐藏字幕信息的情况下，数字电视信号接收机根据标准EIA-708提取和处理数字隐藏字幕信息，或者根据标准EIA-608提取和处理模拟隐藏字幕信息。因此，如果数字节目信号不包括数字闭路字幕，则电视信号处理接收器因此允许用户选择为数字节目信号获得字幕的回退方法。因此，如果数字电视信号不包括数字隐藏字幕信息，则数字电视信号接收机自动处理任何模拟辅助信息，并提供具有适于显示的隐藏字幕信息的电视信号。
