Problems solved by technology

[0014] In addition, when there is a device capable of receiving data other than the destination device to which the data is sent, there is a risk of sending the data to another device by mistake.
Furthermore, some inconvenience may occur as a result of sending data to a device that should not send data in the first place

[0109] -Summary-

[0110] FIG. 1 shows a schematic configuration of an information system 50 according to the first embodiment of the present invention. With reference to Fig. 1, this information system 50 comprises: mobile phone 64, it has via mobile phone network and Internet 62 from the content server 60 (representative is WEB server or mail server) on the Internet download content such as image 90 (or will Contents such as photos are provided as attachments (e-mail data) function, the function of taking images by a digital camera, and the function of transmitting data through IrDA (Infrared Data Association) communication 68; When the mobile phone 64 receives content data that can be displayed or reproduced, it starts the function of displaying or reproducing the content data.

[0111] The content playback system 66 includes a DVD (Digital Versatile Disk) recorder 70 with a hard disk, and a remote controller 74 connected to the DVD recorder 70 with a hard disk through a c...

[0194] -Summary-

[0195] In the first embodiment, IrDA communication is used when transmitting content data from the mobile phone 64 to the DVD recorder 70 with a hard disk. As a medium, IrDA communication uses infrared rays. Since infrared rays are highly directional, there is little possibility that content data sent to a certain receiving device will be received by another device. On the other hand, for example, non-directional radio waves such as wireless LAN and Bluetooth (registered trademark) may be used. It is well known that, for example, when a wireless LAN is used, the communication range is 100 meters or more in radius around the base station of the wireless LAN. Therefore, if the system is constructed in the same manner as in the first embodiment, there is a very high possibility that content data will be reproduced on an unintended receiving device. This situation must be avoided.

[0196] On the other hand, since it is expected that communication methods su...

Abstract

It is possible to transmit data held in a mobile information terminal to a desired device and appropriately process it by an easy procedure. A reception device (410) includes a radio LAN communication unit (420), an infrared-ray reception unit (82), and processing units (422, 424) for subjecting the reception data received by the radio LAN communication unit (420) to a process defined by the reception data received by the infrared-ray reception unit (82) in response to that the infrared-ray reception unit (82) has received data from the same device as the data received by the radio LAN communication unit (420). Thus, the data transmission side can specify transmission of the data to be processed and a process to be performed for it without specifying the process method by the side of the reception device (410).

Description

technical field [0001] The present invention relates to a system for utilizing data stored in portable information terminals in other devices, especially to a mobile phone with a camera, a PDA (Personal Digital Assistant) or a digital camera with a communication function, although any information can be obtained or produced with a portable However, a system in which information stored in a device with a limited information display and reproduction function can be easily used in a device having a more advanced display and reproduction function such as a television receiver or an audio device. Background technique [0002] Multifunctionalization of mobile phones is progressing. Symbolizing the multifunctionality of mobile phones are mobile phones with digital cameras, liquid crystal display devices, and Internet access functions. According to such a mobile phone, an image captured by a digital camera can be sent to a friend via a mobile phone network or the Internet by using ...
