Description

  The present invention relates to an information recording / reproducing apparatus such as a hard disk recorder having a function of causing a display means to display a program guide by EPG data included in a television broadcast signal.

  As is known in the art, a program guide is published in newspapers and magazines in order to inform the viewer of the broadcast schedule of a television program. In addition, in recent years, program guides via the Internet are also well known. In particular, in BS digital broadcasting, EPG (electronic program guide) data is superimposed on a TV broadcast signal and distributed to each home, and television reception at each home is received. The program guide by EPG data can be displayed on the machine, and the program guide can be viewed.

  However, in the guide means based on the program guide published in newspapers and magazines, the title of the program and simple contents are only published mainly due to space limitations, and the contents of the program are given to the viewer. I can't tell you enough. Also, even in the program guide on the Internet or the program guide by EPG, it is only possible to check the title and simple contents of the program on the screen of a television receiver or the like, and the overview of each program is checked with a video. It is not possible.

  By the way, a hard disk device for recording / reproducing video / audio information to / from a hard disk has a function of displaying a program table on a screen of a television receiver or the like by EPG data included in the received television broadcast signal. With this function, the program table is displayed on the screen of a television receiver or the like, and the program title and simple contents can be confirmed. However, even with such a program guide display function of the hard disk device, it is only possible to check the title and simple contents of the program on the screen of a television receiver or the like, and it is not possible to check the outline of each program with video Can not.

Therefore, in the prior art of Patent Document 1, the received video is sampled for a predetermined period, program information is created and stored in the hard disk, and combined with the future program guide, the predicted program information is created and displayed as a moving image. The program contents can be predicted and grasped. In the prior art of Patent Document 2, the program introduction spot transmitted from the transmitter is received and accumulated, and the program summary can be viewed on the EPG screen by a designation operation.

  However, in the prior art of Patent Document 1, for example, when the c channel is received, the predetermined timing is set to 10 minutes, the predetermined period is set to 10 seconds, and a moving image is generated for only 10 seconds from the video received every 10 minutes. By extracting this video and storing it on the hard disk as program information and combining it with future programs, it is possible to create predicted program information and predict and grasp the contents of the program by displaying it as a video. Even if 10 seconds are extracted, since each program is not only a program that ends in 10 minutes, the 10-second video is not necessarily program information of each program.

  That is, in this prior art, as the program of the same channel changes according to the broadcast start time, it is necessary to sample a moving image indicating the contents of each program, but no processing for this is disclosed. Also, for example, if a sampled 10-second moving image is only a commercial, no program is known. So, for example, if you extract 10 minutes of the movie of the program, if the commercial is 1 minute, the program will continue to be played after the commercial ends, so you can understand the contents of the program, but it takes 10 minutes to play, It takes too much time to grasp the contents of the program, which makes it unusable for the user.

  In the prior art of Patent Document 2, as described above, the program introduction spot transmitted from the transmitter is received and accumulated, and the program overview can be viewed on the EPG screen by the designation operation. If the program introduction spot is not transmitted, the program outline cannot be viewed on the EPG screen, and the program introduction spot is not generated on the receiver side and the contents of the program are displayed as a thumbnail as a moving image.
