摘要:
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.
