Abstract
The absence of MPEG processing in a consumer digital recorder player may preclude on-screen message display of recorder status. Various methods are disclosed which facilitate the on-screen display of recorder player status messages. A first embodiment returns a reproduced decoded, analog video signal (102) to the digital recorder player (200) for insertion of status messages. In a further embodiment recorder messages data (221) is coupled to the digital signal decoder (100, 117, 520) for inclusion with the decoded analog video signal (102). In a another embodiment a recorder message command (TAG/CMD) is coupled to the decoder (100, 510) to access recorder specific graphical messages. In yet a further embodiment, recorder message data (221) is tagged and coupled to the decoder (100, 510) to select recorder messaged data. In yet another embodiment, digital or analog operating mode determines recorder (200) message display timing with respect to a reproduced decoded video signal.
