Process recording and data transfer.

Hereinafter, a video and voice e-mail transmission method using the mailing system made as described above will be described.

2 is a flowchart illustrating a system setting process of a mail sender side according to the present invention.

As shown in Fig. 2, the sender first connects the mailing server and the sender system when the user registers. Then, the mailing server first checks the existence of the mailing program of the sender system, and then the mailing program or version. The mailing program automatically checks whether the sender system 30 is provided with a video capturing means such as a PC camera, and sets initial settings for the operation of the mailing program depending on whether the mailing program is equipped with the upgrade. Subsequently, when the sender system is equipped with a PC camera, the mailing program 33 uses the MPEG-4 codec of Microsoft Corporation as an appropriate video compression codec and voice compression codec, i.e., video compression codec. Microsoft's ADPCM codec is used as the voice compression codec. At this time, the mailing program 33 Is installed so that the codec program is automatically updated. The mailing program 33 displays the screen size and the frames per second (FPS) for the video to be captured by the PC camera 38 or the like when the codec is executed. In addition, the recording data amount, time, image quality, etc. are initially set as the basic mode. After initial setting of various optional functions as described above, the mailing program 33 initially sets a preview screen to the sender. The sender system 38 is prepared according to an option and prepares the sender to record or transmit a video / audio message. On the other hand, when the sender system 38 is not equipped with a PC camera or the like, the mailing program 33 An appropriate voice compression codec is executed, that is, the GSM610 codec. As described above, when a video and a voice message are simultaneously transmitted and only a voice message is transmitted, By setting the appropriate compression codec accordingly, the maximum compression ratio and transmission speed for multimedia e-mail can be achieved. This will be described in more detail. First, by connecting to the mailing server 10 After inputting and transmitting his / her own member information (ID, password), the user activates the video / voice mail web document on the homepage of the server (S201).

In addition, when the sender transmits a video / audio mail for the first time through the mailing server 10 or if a version upgrade is required for the mailing program 33 installed in the sender system 30 (S202). The mailing server 10 automatically installs the mailing program 33 in the sender system 30 or executes a version upgrade.

At this time, the mailing server 10 or the mailing program 33 automatically checks whether the sender system 30 is provided with a video capturing means such as a PC camera, and according to whether or not the Initial setting for the operation of the mailing program 33 is performed.

First, when the sender system 30 is equipped with a PC camera, the mailing program 33 designates an appropriate video compression codec and audio compression codec (S205).

At this time, it is preferable to use the MPEG-4 codec of Microsoft Corporation as the video compression codec, and to use the ADPCM codec of Microsoft Corporation as the voice compression codec.

The mailing program 33 may initially set the screen size, the frames per second (FPS), the amount of recording data or the time, the image quality, and the like for the video to be captured through the PC camera 38 as a basic mode. (S206)

After initial setting for various optional functions, the mailing program 33 expresses a preview screen to the sender according to the initial setting option (S207). The sender records or records a video / audio message. It is ready for transmission. (S208)

On the other hand, when the sender system 38 is not equipped with a PC camera, the mailing program 33 designates an appropriate voice compression codec (S209) and sets an initial setting option to sender's voice message mail. Complete preparation for the ring (S210).

In this case, it is preferable to use the GSM610 codec as the voice compression codec.

As such, when the video and voice messages are simultaneously transmitted and only the voice messages are distinguished from each other, an appropriate compression codec is set and used accordingly, thereby achieving the maximum compression rate and transmission speed for the multimedia e-mail.

In the state where the initial setting of the sender system 30 is made as described above, as shown in the flowchart of FIG. 3, the sender records the video / audio message through the option selection buttons presented by the mailing program 33. You can set or adjust various options for transmission according to your needs. The sender can adjust the number of frames (5 ~ 15 fps), set the screen size supported by PC camera, adjust the camera quality, and record the data (500kbyte). , 1Mbyte, etc.) or time, etc. (S301).

At this time, the mailing program 33 processes the video data amount to be almost the same regardless of the sender's screen size setting.

Thus, the sender can not only set the frame rate, recording time or data amount properly in consideration of the data transmission speed, storage capacity, etc., but can also easily change and adjust the size, image quality / sound quality, etc. of the screen to be displayed to the receiver.

Then, the sender selectively records / records a moving picture or a voice message through automatic setting according to whether or not the PC camera 38 is provided or selection of only a voice message required by the user.

First, in the case of a moving picture message, the mailing program 33 records the sender's moving picture message based on the setting options such as the number of frames, the screen size, the camera quality, the amount of recording data, and the time (S303).

In addition, the sender determines whether to send or modify the recorded video message while checking the playback (S304).

In addition, the sender can capture a specific screen of the recorded video screen and save it as a file such as a bitmap, and the sender can change and adjust the screen size at any time for the captured screen.

As the moving image or the screen message is recorded through this process, the sender stores the recorded message data in the storage means for message transmission and later use (S306).

Then, for the voice message, as the sender inputs the voice message, the mailing program proceeds to record the voice message of the sender based on setting options such as the number of frames, the amount of recorded data, and the time (S307).

In addition, the sender determines whether to send or modify the recorded voice message (S308).

At this time, the sender can appropriately change and set the number of frames, the amount of recorded data and the time for the voice message.

When the recording of the voice message is completed through the above process, the mailing program 33 stores and manages the voice message data in the storage means 35 (S309).

In addition, the sender can enter the recipient's e-mail address and the subject, and a simple text message as needed.

Accordingly, the mailing program transmits the sender's video / voice message data to the mailing server 10 using the designated video and voice compression codec (MPEG-4, ADPCM, GSM610, etc.) (S310). The mailing server 10 stores and manages the video DB 14, the voice DB 15, and the text DB 16 of the sender's mail account, respectively (S311).

In addition, the mailing server 10 checks the recipient mail address and transmits the video / audio e-mail to the corresponding mail server (S312).

Accordingly, the receiver accesses the mail server 50 of the receiver and downloads and streams the video / audio e-mail.

4 is a flowchart illustrating a process of confirming receipt of a video / voice mail through a mailing server 10.

As shown in FIG. 4, the receiver accesses the mailing server 10, passes through a predetermined user authentication process, confirms that the video / audio mail has been received in his account, and opens the sent video / voice mail. (S401)

Accordingly, the mailing program 43 at the receiver side buffers and downloads the video / audio compressed data (S402).

When all data is received, the compressed video / audio data is decoded (decompressed) using the designated compression codec (MPEG-4, ADPCM, GSM610, etc.), and the video or audio message is reproduced and displayed to the receiver. (S403)

At this time, the receiver may repeatedly play or store the video / audio message through the interface of the mailing program 43.

In addition, when the receiver wants to write a reply to the sender, as described above with reference to FIG. 3, the receiver may record and record a video or voice message and transmit it to the sender while selecting and adjusting various function options according to their needs. (S404)

FIG. 5 is a view showing an embodiment of an interface screen window of a video / voice e-mail program 33 or 43 according to the present invention. As shown in FIG. 5, the mailing program 33 or 43 is illustrated. ) Provides various settings options for sender and receiver, as well as volume / playback / save / stop / mailing as well as video / audio selection recording, camera options, screen size selection, and multi-function options (frame rate, amount of data or time of recording). to provide.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the technical idea of the present invention.

According to the present invention made as described above, in transmitting a moving picture or voice e-mail having a large amount of data, by selecting an effective compression codec suitable for the user system and the sender of the mail by adjusting the number of frames, the amount of recording or time, etc. By easily changing and setting the amount of mail data, it is possible to improve the transmission speed due to the transmission and reception of electronic mail while ensuring good image quality / sound quality.
