PURPOSE: A digital television status display is provided to receive an ATSC multi-program stream for a single major channel and generate a status display which displays the major channel identifier and a plurality of indicators, each corresponding to a respective one of the minor channels associated with the major channel. CONSTITUTION: A television receiver(90) includes an image format converter, and a state display also includes information concerning the format of the received signal and any format conversion that is currently performed. The television receiver is combined to a digital VCR via a digital communication link. The digital television receiver generates a control panel as to the digital VCR on a display device(98) of the television receiver, and includes an apparatus which receives a command as to the digital VCR and sends the command to the digital VCR via the digital communication link and displays the present status of the digital VCR. The television receiver maintains the status display as to the digital VCR by sending a status change request to the digital VCR as soon as receiving random status change information, and then the VCR responds to the status change request only on a subsequent change in its operational status.
