  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an example of the configuration of a video recording / playback apparatus to which an embodiment of the present invention is applied.

  This video recording / playback apparatus converts a video signal and an audio signal input from a receiving antenna 101 via a TV tuner 102 into digital signals by a video A / D converter 103 and an audio A / D converter 104, respectively. Then, MPEG encoding is performed by the MPEG encoder 105, and this is stored in the DVD-RAM medium 107 inserted in the DVD-RAM drive 106 or the hard disk 108a of the hard disk drive 108 incorporated in the apparatus.

  Then, the MPEG decoder 109 decodes the data stored in these and outputs them to the external TV monitor 112 and the speaker 113 via the video D / A converter 110 and the audio D / A converter 111. These controls are performed by the microprocessor 114 in the apparatus. An Ethernet controller 115, a nonvolatile memory 117, a timer unit 118, and a remote control light receiving unit 119 are connected to the microprocessor 114.

  In the nonvolatile memory 117, bitmap data of a standard logo mark for each broadcasting station is registered in advance.

  Further, this apparatus is equipped with an Ethernet controller 115, and can communicate with the EPG server 120 on the Internet via an external network router 116.

  This apparatus has a function of receiving electronic program guide data from the EPG server 120 via the Internet and displaying the electronic program guide on the TV monitor 112. Further, the present apparatus includes a nonvolatile memory 117, and reservation information for reserved recording can be stored in the memory.

  Further, the timer unit 118 functions to obtain current time information and time elapsed measurement information in the recording reservation function. The remote control light receiving unit 119 has a function of receiving operation information transmitted from the remote controller R wirelessly.

  FIG. 2 shows an example of an electronic program guide displayed on the apparatus.

  This electronic program guide is obtained by displaying the electronic program guide data (generated by program information for each program) received from the EPG server 120 on the Internet via the Ethernet controller 115 in the form of FIG. The program information includes a broadcasting station (station code), a start date / time, an end date / time, and a title. The electronic program guide data generated from the program information received from the EPG server 120 is stored in the hard disk 108a by the hard disk drive 108, and the program guide data is read and displayed each time the program guide is displayed by a user operation.

  In the electronic program guide, a logo mark 201 for each broadcasting station is displayed on the channel number display section at the left end of the program guide. This logo mark is received from the TV tuner 102 or the Internet EPG server 120 for each broadcasting station and stored in the hard disk 108a. For broadcast stations that have not acquired a unique logo mark, a standard logo mark (for example, “terrestrial-A” for terrestrial analog broadcasts and “BS-D” for BS digital broadcasts) is designed according to the broadcast format. Stuff).

  FIG. 3 shows a structure diagram of a logo mark saving file in the hard disk 108a for saving the logo mark of the broadcasting station.
