ABSTRACT:
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.
