Apparatus and method for communicating moving picture mail in a streaming manner
First Claim
1. A method for enabling a moving picture mail server to transmit moving picture mail to a mobile terminal, comprising the steps of:
- (a) when the moving picture mail has arrived, allowing the moving picture mail server to notify the mobile terminal that the moving picture mail has arrived;
(b) when the mobile terminal requests that the moving picture mail be transmitted, transmitting the moving picture mail at a preset transmission rate; and
(c) checking buffering information of the moving picture mail provided from the mobile terminal, setting a new transmission rate according to a change of the buffering information, editing the moving picture mail according to the newly set transmission rate, and performing a transmission operation.

Abstract
A method and apparatus for enabling a moving picture mail server to transmit moving picture mail to a mobile terminal. When the moving picture mail has arrived, the moving picture mail server notifies the mobile terminal that the moving picture mail has arrived. When the mobile terminal requests that the moving picture mail be transmitted, the moving picture mail is transmitted at a preset transmission rate. Buffering information of the moving picture mail fed from the mobile terminal is checked, and a new transmission rate is set according to a change of the buffering information. The moving picture mail is edited according to the newly set transmission rate, and a transmission operation is performed.

4. A method for enabling a mobile terminal to receive moving picture mail from a moving picture mail server, comprising the steps of:
-
(a) when the moving picture mail server notifies the mobile terminal that the moving picture mail has arrived, allowing the mobile terminal to request that the moving picture mail be transmitted;
(b) receiving the moving picture mail from the moving picture mail server, storing the received moving picture mail in a buffer, reproducing data of the received moving picture mail, and buffering other data of the received moving picture mail when an amount of data accumulated in the buffer has reached a predetermined size or more;
(c) allowing the mobile terminal to generate buffering information based upon the amount of data accumulated in the buffer at a predetermined time interval and to transmit the buffering information to the moving picture mail server; and
(d) repeatedly performing an operation for receiving moving picture mail from the moving picture mail server according to a newly set transmission rate based upon the buffering information, storing the moving picture mail in the buffer, and reproducing the moving picture mail. - View Dependent Claims (5)

6. A method for enabling a moving picture mail server to transmit, to a mobile terminal, moving picture mail in which image and audio signals are combined, comprising the steps of:
-
(a) allowing the moving picture mail server to transmit the moving picture mail at a preset transmission rate;
(b) allowing the mobile terminal to buffer received moving picture mail, to reproduce data of the received moving picture mail and to buffer other data of the received moving picture mail, when an amount of buffered data has reached a predetermined size or more;
(c) allowing the mobile terminal to generate buffering information based upon the amount of data buffered at a predetermined time interval and to transmit the buffering information to the moving picture mail server; and
(d) allowing the moving picture mail sever to set a new transmission rate based upon the buffering information from the mobile terminal, to edit the moving picture mail according to the newly set transmission rate, and to perform a transmission operation. - View Dependent Claims (7, 8, 9)

10. An apparatus for enabling a mobile terminal to receive moving picture mail from a moving picture mail server, comprising:
-
a packet disassembler for removing packet headers from packets of the received moving picture mail and disassembling the packets;
a buffer for buffering the moving picture mail of the disassembled packets;
a controller for controlling an operation for outputting the moving picture mail and buffering the received moving picture mail when an amount of data accumulated in the buffer has reached a predetermined size or more, and generating buffering information based upon the amount of data accumulated in the buffer at a predetermined time interval, and transmitting the buffering information to the moving picture mail server;
an image codec for decoding a moving picture signal output from the buffer; and
a display unit for displaying the decoded moving picture signal output from the image codec.

11. An apparatus for enabling a mobile terminal to receive moving picture mail from a moving picture mail server, the moving picture mail being a signal in which image and audio signals are interlaced and combined, comprising:
-
a packet disassembler for removing packet headers from packets of the received moving picture mail and disassembling the packets;
a buffer for buffering the moving picture mail of the disassembled packets;
a controller for controlling an operation for outputting data of the received moving picture mail and buffering other data of the received moving picture mail when an amount of data accumulated in the buffer has reached a predetermined size or more, and generating buffering information based upon the amount of data accumulated in the buffer at a predetermined time interval, and transmitting the buffering information to the moving picture mail server;
a header analyzer for analyzing headers of the moving picture mail output from the buffer and generating a control signal necessary for separating the image and audio signals from the moving picture mail;
a splitter for separating the image and audio signals from the moving picture mail in response to the control signal;
an image codec for decoding the separated image signal output from the buffer;
a display unit for displaying a moving picture signal output from the image codec; and
an audio codec for decoding the separated audio signal.
