4 is a flowchart illustrating another example of a method for transmitting and receiving multimedia data according to a preferred embodiment of the present invention. The example shown in Fig. 4 shows an example in which the multimedia data transmitting / receiving apparatus 200 of the present invention is implemented as an e-mail server.

Referring to FIG. 4, a method of transmitting and receiving multimedia data according to a preferred embodiment of the present invention will be described. First, the multimedia data transmitting and receiving apparatus 200 receives email data from a sender terminal 100 (S410) Whether the moving image data is included or not is checked. If the moving image data is not included, the operation proceeds to step S441.

If the received e-mail contains moving image data, the multimedia data transmitting / receiving device 200 divides the moving image data by time unit or key frame unit (S431), and stores the divided moving image data in advance A view image is generated and stored (S433).

When the receiver terminal 300 logs in (S441), the multimedia data transmitting and receiving apparatus 200 transmits the list of e-mails sent to the receiver to the receiver terminal 300 (S443) And outputs the selected list to the receiver, selects the mail from the receiver, and transmits the selected information to the multimedia data transmitting / receiving device 200 (S445).

 The multimedia data transmitting and receiving apparatus 200 checks whether the mail selected by the recipient terminal 300 is a mail attached with the moving image or not (S447). If the moving image is not attached, the multimedia data transmitting and receiving apparatus 200 transmits the mail content to the recipient terminal 300 (S448), and the recipient terminal 300 displays the contents of the mail to the recipient (S449).

When the recipient selects the mail attached with the moving image, the multimedia data transmission / reception device 200 transmits the preview image and the mail contents to the recipient terminal 300 (S451) The preview images are displayed together (S453).

The recipient terminal 300 checks whether the recipient selects the divided moving image data. If the divided moving image data is not selected, the recipient terminal 300 displays only the mail content and terminates (S461). The reason why the recipient has not selected the divided moving image attached to the mail is that the recipient judges from the preview image that the recipient does not desire it.

Meanwhile, when the receiver selects the divided moving picture data, the recipient terminal 300 requests the multimedia data transmission / reception device 200 to download the divided moving picture data selected by the recipient (S463), and the multimedia data transmission / reception device 200 The receiver terminal 300 transmits the divided moving image data requested by the receiver terminal 300 to the receiver terminal 300 in step S465 and the receiver terminal 300 stores the divided moving image data received from the multimedia data transmitter and receiver 200 in step S467. .

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner.

The present invention has been described with reference to the preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
