Abstract

A television receiver which receives an ATSC multi-program stream for a single major channel and generates 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. The indicator corresponding to the minor channel that is currently selected is highlighted with respect to the other indicators. The television receiver includes an image format converter and the status display also includes information concerning the format of the received signal and any format conversion that is currently being performed. The television receiver is also coupled to a digital VCR via a digital communications link. The digital television receiver generates a control panel for the digital VCR on the display device of the television receiver, and includes a facility for receiving commands for the digital VCR, sending the commands to the digital VCR via the digital communications link displaying the current status of the digital VCR. The television receiver maintains the status display for the digital VCR, by sending a status change request to the digital VCR immediately after receiving any status change information, whereby the VCR responds to the status change request only on a subsequent change in its operational status.

Claims

1. A method for displaying the status of a digital television receiver which receives an Advanced Television Systems Committee (ATSC) multi-program stream comprising the steps of:

displaying an identifier for a major channel transmitted in the ATSC multi-program stream;

displaying a plurality of indicators, each of the indicators corresponding to a respectively different one of a plurality of minor channels within the major channel for a single major channel; and

highlighting one of the minor channel indicators to indicate that video information in the respective minor channel is being decoded and displayed.

2. A status display method according to claim 1, wherein the digital television receiver includes an image format converter which converts images generated from the one minor channel to a format compatible with a display device that may be coupled to the television receiver, the method further comprising the step of displaying information concerning the format of the received signal and any format conversion that is currently being performed.

3. Apparatus for displaying the status of a digital television receiver which receives an Advanced Television Systems Committee (ATSC) multi-program stream comprising:

means for displaying an identifier for a major channel transmitted in the ATSC multi-program stream;

means for displaying a plurality of indicators, each of the indicators corresponding to a respectively different one of a plurality of minor channels within the major channel for a single major channel; and

means for highlighting one of the minor channel indicators to indicate that video information in the respective minor channel is being decoded and displayed.

4. A status display apparatus according to claim 3, wherein the digital television receiver includes an image format converter which converts images generated from the one minor channel to a format compatible with a display device that may be coupled to the television receiver, the apparatus further comprising means for displaying information concerning the format of the received signal and any format conversion that is currently being performed.
