COMBINATION OF RECORDED PROGRAM INDEX AND EPG
A television system has a television viewing mode and a guide mode. The guide mode includes an electronic program guide (EPG), which provides the viewer program information for tuned programs, and a tape index guide (TIG), which provides information for programs recorded on a video cassette. In both guides, real time images of a program are displayed in a PIP window on the television screen and guide information is displayed in the background. In both guides, the viewer may switch between a currently telecast program or a recorded program. The viewer may access either guide from the television mode and vice versa. In the guide mode, the viewer may independently switch the guide information and the type of program, i.e., tuned or recorded, in the PIP window.

This invention relates to the field of television, and more particularly to a method and apparatus for switching between a television viewing mode and a guide mode which comprises program guide screens, for telecast programs, and video tape index guide screens, for recorded programs.
BACKGROUND OF THE INVENTIONTelevision systems are available which include various types of on-screen guides to provide a viewer with information about available programs. Electronic program guides (EPG) provide information about currently telecast programs and programs to be broadcast in the future. An EPG includes program listings which provide time, channel, length, and title information for a program and may also provide a brief description of the content of the program in a separate portion of the screen. Many EPG systems have the capability to sort program listings by type, time, or viewer preferences.
Tape indexing systems for video cassette recorders (VCR) allow a viewer to identify a recorded program stored in the viewer's video tape library. Such systems also provide an on-screen directory of programs available on a loaded tape and can automatically scan through the video tape to the position of the desired program stored on the tape.
Some types of EPG and tape index guides include screens with a picture in picture (PIP) window for displaying moving, real time images or still images from a selected television program.
It is desirable to provide a television system which has both types of guides, i.e., an EPG and a tape index guide, and which facilitates navigation in a guide mode between the various guide screens and between the guide mode and a normal television viewing mode, in which a selected television program is viewed full screen.
It is also desirable to provide a viewer with the capability to control which program is displayed in the PIP window in the guide mode in the same manner the viewer would in the normal television viewing mode. This includes switching between tuned channels or between the outputs of the tuner and the VCR.
SUMMARY OF THE INVENTIONA television system according to the present invention includes a tape indexing and searching (TIS) apparatus for generating a tape index display, an electronic program guide (EPG) apparatus for generating an EPG display, a VCR for playing recorded television programs, and a tuner for receiving broadcast television programs. The video outputs of the two guide apparatus are connected to a guide switch and the video output of the tuner and the VCR are connected to a program source switch. A PIP chip is operatively connected to the guide switch and the program source switch such that in an active mode the PIP chip displays on a television screen a PIP window displaying the moving, real time images of a selected program overlaid on a background comprising selected guide information.
Preferably a microprocessor controls and coordinates the operation of the PIP chip and the switches so that the viewer may navigate between the various screens of the guide mode and the normal television viewing mode, and display a desired program in the PIP window.
By pressing a guide/tv button on the remote controller, the viewer may enter either an EPG or tape index guide from the normal television mode and also return to the television mode from either type of guide. In either the television or guide mode, a program source button toggles the program display between a tuned program and a recorded program playing on the VCR. In the guide mode, a guide/index button toggles between the EPG and the tape index guide. In the television mode, a PIP button allows the viewer to view the program being output from one program source, i.e., the tuner or the VCR, while viewing the program output from the other program source full screen.
The features of a specific embodiment of the best mode contemplated of carrying out the invention are illustrated in the drawings, in which:
A television system according to a presently preferred embodiment of the invention combines an electronic program guide (EPG) and a tape index guide. The EPG is of the type which provides one or more screens of program listings. These listings may include currently telecast programs and programs to be broadcast in the future. The program listings are sorted by category and by time in different screens of the guide. The EPG includes a picture in picture (PIP) window for display of a currently telecast program. The viewer may change the program displayed in the PIP window by cursoring through listings of currently telecast programs in one of the guides.
The tape index guide system is of the type which is provided with a VBI decoder to decode information, such as title, channel, date, time, and length of broadcast programs and utilizes the information in providing a directory of programs stored on a recorded tape and for controlling the VCR. The tape index guide system is also provided with a VBI encoder for inserting control and directory information onto the tape on which the broadcast program is being recorded, either in the VBI portions of the video track or in the control track of the tape. From the control and directory information stored on the tape, the tape index guide system creates a program directory which may be displayed on the screen. The directory enables the viewer to determine the location of a recorded program in his or her tape library and control the playing of a selected program on a tape loaded in the VCR. The on-screen directory includes a PIP window. The PIP window may be used to display an entire selected program or a selected video clip from the program as the program listing is selected in the directory.
The television system according to the invention allows the viewer access to either type of guide, i.e., EPG or tape index guide, from a television mode and also allows navigation between the two guides in a guide mode.

The operation of the apparatus will now be described starting in the television mode with PIP chip 23 turned off. In the television mode, moving, real time images of a program are displayed full screen on the television. The program displayed may be either a currently telecast program being received by tuner 12, or a recorded program played from a video tape loaded in VCR 16. Switch 14 controls whether the video input to the television is from the tuner 12 or the VCR 16. Switch 14 is controlled by the PLAY button 32 on the remote controller 26. By pressing the PLAY button, the viewer controls the input source to the television and switches between the currently telecast program output from the tuner and the recorded program being output by the VCR, as shown in
According to a presently preferred embodiment, the viewer is able to select between a EPG, a tape index guide, and a normal television mode. As used herein, “television mode” refers to normal television viewing wherein a currently telecast or recorded program is displayed full screen. “Guide mode” refers to displaying one of the guide screens according to the invention, which may be either an EPG or a tape index guide. The guide screens comprise graphics in the background area 52 and a program being displayed in the PIP window 50.
The GUIDE/TV button on the remote controller 26 controls guide switch 20 and PIP chip 23 and is used to switch between the television mode and the guide mode. When the viewer presses GUIDE/TV button 28, PIP chip 23 is turned on, guide switch 20 couples EPG apparatus 18 or TIS apparatus 22 to PIP chip 23, and television 28 displays an EPG or tape index guide, respectively.
Preferably, the microprocessor controlling guide switch 20 is sensitive to the condition of program source switch 14 so that when switch 14 is switched to tuner 12, the microprocessor controls guide switch 20 to couple EPG apparatus 18 to PIP circuit 23 when the GUIDE/TV button 28 is pressed. This causes television 24 to display the screen of
Alternatively, if switch 14 is switched to VCR 16 in the television mode and the viewer presses GUIDE/TV button 28, PIP chip 23 is turned on, and the microprocessor controls guide switch 20 to couple TIS apparatus 22 to television 24 so that tape index guide information is displayed in background area 52 with the program output from the VCR displayed in PIP window 50, as shown in
In another preferred embodiment, if the tape playing in the VCR is encoded with control and directory information, the tape index guide screen of
Due to the mechanical limitations of the VCR, locating a selected program on a videotape may take the up to a minute or more. Accordingly, it is desirable to delay such a program search by the VCR until the viewer is committed to searching for the recorded program on the tape. This is accomplished in the following alternate embodiments: in one embodiment, the program search is delayed until the program listing in listing area 58 is highlighted with cursor 60 for a set period of time, e.g., 5 seconds. In another embodiment, the viewer initiates a search by positioning cursor 60 on the desired program and then pressing a set sequence of buttons on the remote controller to command TIS apparatus 22.
According to alternate embodiments of the invention, once the selected program, e.g., “When You Wish Upon A Star” in
While in the guide mode, INDEX button 30 controls switch 20. Thus, from an EPG screen such as that shown in
PLAY button 32 controls program source switch 14 in either the television mode or the guide mode to switch between tuner 12 and VCR 16. Thus, the viewer may switch between the program output by VCR 16 and the program output by tuner 12 in the PIP window 50 while in the guide mode. Also, if a tape is loaded in VCR 16 and is not playing, pressing PLAY button 32 will cause the VCR to begin playing the tape when switching program source switch 14 from tuner 12 to VCR 16. Preferably a highlighted area 62 which includes the program listing for the program tuned by the tuner is included in area 52 of the tape index guide screens. This allows the viewer to identify the currently telecast program displayed in the PIP window 50 while in the tape index guide.
Preferably, if the viewer enters the tape index guide from the EPG and no video tape is loaded in VCR 16, television 24 displays the screen of
The viewer may exit the guide mode, from either the EPG or the tape index guide, using GUIDE/TV button 28. When the user presses the GUIDE/TV button while in the guide mode, the PIP chip 23 is turned off. Thus, the program source to which program source switch 14 is switched, i.e., tuner 12 or VCR 16, will be directly coupled to the television and the program output from that program source will be displayed full screen, as shown in
In all the described modes, the sound accompanying the video program displayed in PIP window 50 is reproduced by the loudspeaker of television 24.
According to yet another alternate embodiment of the invention, the apparatus may be configured to display a PIP window 60 in the television mode, thereby allowing the viewer to view the recorded program being output by VCR 16 and the currently telecast program being output by tuner 12 simultaneously. As shown in
Although certain preferred embodiments of the present invention have been described herein, many modifications and variations will be apparent to those skilled in the art. It is therefore to be understood that the scope of the invention should be limited only by the appended claims.
