This configuration is basically the same as the mobile terminal devices 12 and 13 in the first embodiment, but the mobile terminal devices 212 and 213 are provided with an audio localization unit 161 for the audio processing unit 160. Yes. In the third embodiment, the audio processing unit 160 and the audio localization unit 161 function as a content presentation unit that presents where and what content is distributed.

The sound localization unit 161 freely sets the position of the output sound image (virtual sound source). The sound localization here is to generate sound so that the listener can hear the sound from a virtual position and direction. For example, the position of the sound image in the left-right direction can be changed by changing the balance between the left and right sounds with stereo channel sound. Furthermore, if a sound source with a plurality of channels is used, the position of the sound image can be freely set.

Thus, in the third embodiment of the present invention, the audio localization unit 161 is provided for the audio processing unit 160. In addition, communication is performed between the mobile terminal device 213 outside the content available area and the mobile terminal device 212 inside the content available area. Then, the mobile terminal device 212 in the content available area transmits the related information of the content accessed by the mobile terminal device 212 itself and the location information of the mobile terminal device 212 to the mobile terminal device 213 outside the content available area. . The mobile terminal device 213 outside the content useable area outputs the content-related information by voice localization in the direction of the mobile terminal device 212 inside the content useable area, so that the user of the mobile terminal device 213 is where and how It is possible to intuitively understand whether or not content is distributed.

In the above, in the area-limited content distribution service, the mobile terminal device outside the content available area presents the related information of the content accessed by the mobile terminal device in the content available area (for example, display or audio output). However, the application range of the present invention is not limited to such an area-limited content distribution service. In the content distribution system according to the present invention, for example, when music content is shared between mobile terminal devices, who has what content (that is, which mobile terminal device stores what content) Yes, it can be used for a service that users can present at a glance. In the present invention, it is also possible to make it possible for the map display application program to know what content was available in which area within the past 24 hours, for example, by utilizing position information. .

Note that the first, second, and third embodiments described above may be combined. For example, as described in the first embodiment, the mobile terminal device outside the content available area displays the content related information in the captured image, and further performs audio output of the content related information by sound localization, Content related information may be presented.

Note that a program for realizing all or part of the functions of the control units 51 and 151 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. You may process each part by. Here, the “computer system” includes an OS and hardware such as peripheral devices.
Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM or a CD-ROM, and a hard disk incorporated in a computer system.
