Abstract

Apparatus and methods are provided for selecting channels on a television system by theme. A remote controller for the television system includes a plurality of theme keys, each theme key corresponding to one theme of a plurality of themes, apparatus for entering channel indicators corresponding to each theme, apparatus for storing the entered channel indicators corresponding to each theme, apparatus for accessing and transmitting to the television system each channel indicator corresponding to a first theme of the plurality of themes in sequence to control channel selection for the television system, if a first theme key corresponding to the first theme is pressed, apparatus for pausing a set period of time after accessing and transmitting a channel indicator before continuing to access and transmit channel indicators corresponding to the first theme in sequence, and apparatus for stopping the apparatus for accessing and transmitting from accessing and transmitting each channel indicator corresponding to a first theme of the plurality of themes in sequence, if the first theme key is pressed again.

Claims

1. A method for surfing a spectrum of television channels on which programs are telecast, the method comprising the steps of:

tuning a television receiver to a given channel;

displaying on a television screen a foreground field and a background field;

inserting the program being telecast on the given channel in one of the fields;

sequentially inserting programs being telecast on other channels in the other field;

generating a full screen command signal; and

displaying on the screen full frame the program being telecast on the other channel when the command signal is generated.

2. The method of claim 1, additionally comprising the step of generating a channel sequencing command signal and the sequentially inserting step inserts a program each time the channel sequencing command signal is generated.

3. The method of claim 2, in which the sequentially inserting step inserts a program if the sequencing command signal is not generated after a set period of time.

4. The method of claim 1, in which the foreground field is a PIP window and the step of sequentially inserting the programs being telecast on other channels inserts the programs in the PIP window.

5. The method of claim 2, in which the other field is a PIP window and the step of sequentially inserting programs being telecast on the other channels inserts the programs in the PIP window.

6. A method of surfing a spectrum of television channels that carry programs with a television receiver having a display monitor and a channel selector, the method comprising the steps of:

storing in a memory a group of channels and time periods of the day when individual channels of the stored group are enabled for viewing;

sequentially retrieving the enabled channels of the group during each time period;

sequentially setting the channel selector to each of the retrieved channels; and

sequentially displaying the programs on each of the retrieved channels on the monitor.

7. The method of claim 6, in additionally comprising the step of issuing sequential commands that control the retrieving, setting, and displaying steps.

8. The method of claim 7, in which a hand held remote controller issues the commands responsive to manual inputs.

9. The method of claim 8, in which a command is issued after a set period of time if no manual input occurs.
