Abstract

The invention provides an electrical program guide system and method by which a desired program can be rapidly selected directly from among a large number of programs with certainty. A program selection screen as a multi-screen is formed from nine reduced screens reduced to one third in the horizontal and vertical directions from screens of programs broadcast on different broadcasting channels. A plurality of such program selection screens are transmitted to a reception side. On the reception side, the program selection screens are stored into a virtual frame memory so that reduced screens of them may make a single virtual screen. From among the reduced screens of the virtual frame, desired 3×3 reduced screens are read out and displayed on a multi-screen of full motion. A viewer finds and directly selects a desired program from within the 3×3 reduced screens of full motion displayed as the multi-screen. The array of the reduced screens can be automatically changed, based on program enjoyment histories, so that a reduced screen of a program enjoyed frequently by the viewer is disposed at a position which facilitates selection by the viewer such as the upper left position of the screen. The array may be customized such that it is changed to an arbitrary array based on a desire of the viewer.

Claims

1. A reception apparatus for receiving a program selection screen for selection of a plurality of programs of different broadcasting channels, comprising:

reception means for receiving a plurality of program selection screens, wherein each one of said plurality of program selection screens has arranged thereon a plurality of reduced screens corresponding to said plurality of programs of different broadcasting channels;

display means;

storage means for storing said plurality of program selection screens received by said reception means, said storage means arranging said plurality of program selection screens on a virtual screen such that said virtual screen has a greater number of reduced screens arranged thereon than can be displayed simultaneously on said display means;

designation means for allowing a user to scroll relative to said virtual screen in order to selectively designate for display on said display means an array of reduced screens forming a portion of said virtual screen of said storage means, said designation means enabling said user to scroll left, right, up, and/or down to regions of said virtual screen not presently being displayed to said user; and

outputting means for reading out and outputting to said display means said selectively designated array of reduced screens from said virtual screen of said storage means.

2. The reception apparatus according to claim 1, wherein said reception means receives said plurality of program selection screens from one transmission channel.

3. The reception apparatus according to claim 1, further comprising array control means for controlling a scrolling operation of said designation means for selectively scrolling through said plurality of reduced screens located at various positions on said virtual screen in order to designate said array to be displayed.

4. The reception apparatus according to claim 3, wherein said array control means reads out said array of reduced screens from said virtual screen of said storage means after arranging said plurality of reduced screens into individual program categories.

5. The reception apparatus according to claim 3, further comprising array designation means for designating a plurality of array positions in said storage means for a plurality of arrays of reduced screens when said plurality of reduced screens are stored in said storage means.

6. The reception apparatus according to claim 5, further comprising changing means for changing said plurality of array positions of said plurality of arrays of reduced screens stored in said storage means.

7. The reception apparatus according to claim 6, wherein said changing means changes said plurality of array positions of said plurality of arrays of reduced screens stored in said storage means in accordance with an enjoyment history of programs watched by a viewer.

8. A reception method for receiving a program selection screen for selection of a plurality of programs of different broadcasting channels, comprising the steps of:

receiving a plurality of program selection screens, wherein each one of said plurality of program selection screens has arranged thereon a plurality of reduced screens corresponding to said plurality of programs of different broadcasting channels;

storing said received plurality of program selection screens such that said received plurality of program selection screens are arranged on a virtual screen such that said virtual screen has a greater number of reduced screens arranged thereon than can be displayed simultaneously on a display device;

scrolling left, right, up, and/or down relative to said virtual screen in order to access regions of said virtual screen not presently being displayed to a user;

selectively designating for display an array of reduced screens from said virtual screen;

reading out and outputting to said display device said designated array of reduced screens from said virtual screen; and

displaying said designated array of reduced screens from said virtual screen on said display device.

9. A broadcasting system wherein a program selection screen for selection of a plurality of programs of different broadcasting channels is transmitted from a transmission apparatus and received by a reception apparatus, comprising:

transmission means provided in said transmission apparatus for multiplexing and transmitting a plurality of program selection screens, wherein each one of said plurality of program selection screens has arranged thereon a plurality of reduced screens corresponding to said plurality of programs of different broadcasting channels;

reception means provided in said reception apparatus for receiving said plurality of program selection screens;

storage means provided in said reception apparatus for storing said plurality of program selection screens received by said reception means, said storage means arranging said plurality of program selection screens on a virtual screen such that said virtual screen has a greater number of reduced screens arranged thereon than can be displayed simultaneously on a display device;

designation means cooperating with said reception means for allowing a user to scroll left, right, up, and/or down relative to said virtual screen in order to selectively designate for display on said display device an array of reduced screens forming a portion of said virtual screen of said storage means, said designation means enabling said user to scroll to regions of said virtual screen not presently being displayed to said user; and

outputting means provided in said reception means for reading out and outputting to said display device said selectively designated array of reduced screens from said virtual screen of said storage means.

10. A broadcasting method wherein a program selection screen for selection of a plurality of programs of different broadcasting channels is transmitted from a transmission apparatus and received by a reception apparatus, comprising the steps of:

multiplexing and transmitting, using said transmission apparatus, a plurality of program selection screens, wherein each one of said plurality of program selection screens has arranged thereon a plurality of reduced screens corresponding to said plurality of programs of different broadcasting channels;

receiving, using said reception apparatus, said plurality of program selection screens;

storing in said reception apparatus said received plurality of program selection screens in such a way that said plurality of program selection screens are arranged on a virtual screen such that said virtual screen has a greater number of reduced screens arranged thereon than can be displayed simultaneously on a display device;

scrolling relative to said virtual screen using a designation apparatus cooperating with said reception apparatus, said scrolling enabling a user to scroll left, right, up, and/or down to access regions of said virtual screen not presently being displayed to said user;

selectively designating for display an array of reduced screens from said virtual screen; and

reading out and outputting to said display device, using said reception apparatus, said selectively designated array of reduced screens from said virtual screen.
