Abstract

A television system comprises an electronic program guide (EPG) including a picture-in-picture (PIP) window and means for returning to a last channel viewed full screen (LCF) in a television viewing mode prior to entering the guide mode. The EPG displays a program list including a listing for the LCF and text identifying it as such. This last channel listing is positioned at the top of a program list area in the guide. The viewer returns directly to the LCF in the television viewing mode by setting a cursor to the last channel listing prior to exiting the guide mode. In guides including listings for future programs, the last channel listing remains in a designated position of the program list area. To return to the LCF from the guide mode, the viewer cursors to the last channel listing in the program list and then presses a GUIDE/TV button, designates the LCF as the default channel to which the system automatically tunes when exiting the guide mode, or presses a LAST CHANNEL button on the remote control unit to simultaneously exit the guide mode and tune the system to the LCF. Alternately, the system may employ separate television and PIP tuners. In the guide mode, the television input is switched to the PIP tuner and the television tuner remains tuned to the LCF. Thus, when the viewer reselects the television viewing mode, the program being telecast on the LCF is displayed full screen.

Claims

1. A method for channel grazing from an electronic program guide of a television apparatus having a screen, a tuner, and a memory, the method comprising:

storing a plurality of program listings in the memory;

changing to a program guide mode in which a portion of the program listings are displayed on the screen;

storing a channel tuned to by the tuner prior to changing to the program guide mode as a last channel;

displaying the last channel as a last channel listing with the program listings in the guide mode;

selecting one of the displayed program listings;

setting the tuner to a channel carrying a first program indicated by the selected program listing;

displaying the first program in a PIP window in the guide mode;

selecting the displayed last channel listing;

setting the tuner to the last channel; and

changing to a television viewing mode to display a second program carried by the last channel in a full screen format.

2. The method of claim 1, wherein the last channel listing remains in a fixed position on the screen.

3. The method of claim 1 further comprising changing the displayed program listings while continuing to display the last channel listing.

4. A system for channel grazing from an electronic program guide of a television apparatus, the system comprising:

means for storing a plurality of program listings in the memory;

means for changing to a program guide mode in which a portion of the program listings are displayed on the screen;

means for storing a channel tuned to by the tuner prior to changing to the program guide mode as a last channel;

means for displaying the last channel as a last channel listing with the program listings in the guide mode;

means for selecting one of the displayed program listings;

means for setting the tuner to a channel carrying a first program indicated by the selected program listing;

means for displaying the first program in a PIP window in the guide mode;

means for selecting the displayed last channel listing;

means for setting the tuner to the last channel; and

means for changing to a television viewing mode to display a second program carried by the last channel in a full screen format.

5. The system of claim 4 further comprising means for maintaining the last channel listing in a fixed position on the screen.

6. The system of claim 4 further comprising means for changing the displayed program listings while continuing to display the last channel listing.

7. A system for channel grazing from an electronic program guide of a television apparatus, the system comprising:

a memory for storing a plurality of program listings;

a tuner for tuning to a channel;

means for changing to a program guide mode;

a last channel register coupled to the memory, the last channel register storing the channel tuned to by the tuner prior to changing to the program guide mode;

a screen coupled to the memory and the last channel register, the screen displaying the last channel as a last channel listing with the program listings in the guide mode;

means for selecting one of the displayed listings;

a microprocessor coupled to the tuner and the means for selecting, the microprocessor setting the tuner to the channel carrying a program indicated by the selected listing; and

a PIP chip coupled to the microprocessor, the PIP chip displaying a program being telecast on the channel to which the tuner is set.

8. The system of claim 7 wherein the tuner is set to the last channel in the last channel register.

9. The system of claim 7 further comprising means for changing to a television viewing mode to display the program being telecast on the channel to which the tuner is set in a full screen format.
