摘要： A system as described herein enables a user to access auxiliary information when viewing an enhanced performance television signal or program. Particularly, a television signal system is operative, configured, and/or enabled to allow a user to access and/or utilize auxiliary information when viewing a high definition or progressive-scan television signal. Briefly, an exemplary television signal system receives the auxiliary information/data (e.g. closed caption data) on a selected interlaced standard definition input, processes the auxiliary data, and combines or overlays the auxiliary data with a television (video) signal received on a selected input that does not have its own embedded auxiliary information/data. More particularly, an exemplary television signal system such as described herein involves using closed caption (CC) data from a standard definition signal, processing the CC data, and overlaying the CC data at a video rate of a higher definition signal selected for viewing that does not carry its own embedded closed caption data.
