Access information (URL: //ddd.eeee.fff.XXX) and access information (URL: //xxx.yyy.zzz.XXX) for only the moving image data component are also added.

  Accordingly, the cellular phone B1-2 receives an e-mail in which the access information to the moving image data with audio, the access information to only the audio data, and the access information to only the moving image data are added. FIG. 9 shows a screen image of the mobile phone B1-2 on the receiving side.

  In FIG. 9 (a), in addition to the screen image [FIG. 8 (a)] described in the embodiment of the present invention described above, access information for only moving image data is also added. When the user of the mobile phone B1-2 on the receiving side selects access information for only moving image data from among the three pieces of access information displayed on the screen by the key operation unit 12-2, the above-described embodiment of the present invention is described. Similarly to the above, by communicating with the mail server 4, it is possible to acquire only moving image data and reproduce only moving image data [see FIG. 9B].

  Thus, in this embodiment, since only moving image data can be acquired, the amount of data is smaller for moving image data alone than for moving image data with sound, as in the above-described embodiment of the present invention. Thus, the communication amount (packet amount) can be suppressed, and the burden of communication cost (packet fee) can be reduced.
