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 to the digital recorder player for insertion of status messages. In a further embodiment recorder message data is coupled to the digital signal decoder for inclusion with the decoded analog video signal. In a another embodiment a recorder message command is coupled to the decoder to access recorder specific graphical messages. In yet a further embodiment, recorder message data is tagged and coupled to the decoder to select recorder specific graphical messages if available or to display recorder message data. In yet another embodiment, digital or analog operating mode determines recorder message display position and timing.
