  Some recent recording apparatuses not only receive TV programs but also have a communication function for communicating with an external communication apparatus. Some recent PCs (Personal Computers) have a TV tuner for receiving TV programs and a large-capacity HDD (Hard Disk Drive) capable of recording TV programs in addition to the above communication functions. To do. Therefore, when recording a TV program, it has been proposed to use the communication function to provide various conveniences to the user.

  For example, in the video operation system described in Patent Document 1, the video operation server can communicate with a mobile phone via the Internet and can communicate with a video deck via a wireless interface. When the video operation server transmits the program broadcast schedule to the mobile phone and receives the operation signal of the video deck from the mobile phone, the video operation server converts it into a format according to the video deck and transmits it to the video deck. Thus, the video deck can be remotely operated based on an operation command from the mobile phone. Therefore, operations such as recording reservation and playback for the video deck can be easily performed without going to the place where the video deck is installed.

  There has also been proposed a method for using a communication function so as not to miss a program desired by a user.

  For example, in the information processing system described in Patent Document 2, first, an electronic program guide is displayed on a user's mobile phone, and a desired program is marked from each program. Next, the mobile server device compares the broadcast start time and broadcast end time of the program marked by the user with schedule data indicating the user's schedule that is stored and controlled separately from the user. When the broadcast time of the marked program overlaps with the user's schedule, the mobile server device transmits a message prompting the user to set recording by remote operation of the marked program to the mobile phone of the user. As a result, the user can perform recording setting from the mobile phone to the video tape recorder device via the Internet or the like based on the message, and can prevent the marked program from being overlooked.

In addition, the recording device described in Patent Literature 3 performs program reservation based on program reservation information received from the mobile terminal device via the Internet or the like, and can communicate with the mobile terminal device via short-range wireless communication. On the other hand, it is determined that the reserved program is being viewed, and recording of the program is prohibited. Thus, even if the program is reserved for recording, when the user is watching the program, the program is not recorded, so that the recording medium can be used effectively. In addition, when the recording device can communicate with the mobile terminal device via short-range wireless communication, the recording device notifies that the scheduled recording time has come or is approaching.
