Abstract

The invention relates to a method for communicating multimedia data between electronic devices by means of IR ray, which comprises the steps of converting data to be transmitted into a document by a document processing program installed in an electronic device for transmission, appending a filename extension thereto for classifying the document, transmitting the document through an IR transceiving control signal by an IR transceiver of the said electronic device, receiving the control signal as an indicative of the transmitted document by another electronic device for receiving, and identifying and processing the received document based on the filename extension thereof so as to create an identifiable data.

Claims

1. A method for communicating multimedia data between an electronic device for transmission and an electronic device for receiving by means of IR (infrared) ray comprising:

converting data to be transmitted into a document by a document processing program installed in the electronic device for transmission;

appending a filename extension to the document for classifying the document;

transmitting the document through an IRCS (IR transceiving control signal) by an IR transceiver of the electronic device for transmission;

receiving the IRCS as an indicative of the transmitted document by the electronic device for receiving; and

identifying and processing the received document based on the filename extension thereof so as to create an identifiable data.

2. The method of claim 1, wherein each of the electronic device for transmission and the electronic device for receiving comprises:

an information processing module implemented as a CPU (central processing unit) and including the document processing program;

a data storage module for receiving an ACS (access signal) for accessing data;

an IR communication module consisting of the IR transceiver and an IR protocol for receiving an IRS (IR transceiving signal) for transceiving data; and

a display module for receiving a DSS (display signal), displaying messages, and prompting.

3. The method of claim 2, wherein the electronic device for transmission performs the following steps to transmit data:

(a) commanding the information processing module to assemble a name of the document, a filename extension of the document, and data contained in the document to form a complete document to be transmitted based on a data structure of the document;

(b) storing the complete document in the data storage module;

(c) receiving the IRCS for analysis and processing;

(d) determining whether the received IRCS is one defined by a system;

(e) if a result of the determination in step (d) is positive and if the electronic device for transmission is in a standby mode, the electronic device for transmission outputs the IRS, the ACS and the DSS to the IR communication module, the data storage module, and the display module respectively based on the received IRCS;

(f) determining by the system whether there is a response signal;

(g) if a result of the determination in step (f) is positive performing a frame processing on the document in the data storage module by the information processing module prior to transmission;

(h) determining whether a last framed document is met during the transmission of the framed document; and

(i) if a result of the determination in step (h) is positive, deactivating the IR transceiver of the electronic device for transmission and releasing a memory occupied by the framed document prior to completion.

4. The method of claim 3, wherein if the result of the determination in step (d) is negative and if the electronic device for transmission is not in the standby mode, analyzing and processing the received IRCS.

5. The method of claim 3, wherein if the result of the determination in step (f) is negative, analyzing and processing the received IRCS.

6. The method of claim 3, further comprising showing messages on the display module during the transmission of the framed document so as to interrupt the same if necessary.

7. The method of claim 3, wherein if the result of the determination in step (h) is negative, analyzing and processing the received IRCS.

8. The method of claim 3, wherein the electronic device for receiving performs the following steps to receive data:

(j) commanding the information processing module to receive the IRCS for analysis and processing;

(k) determining whether the received IRCS is one defined by the system;

(l) if a result of the determination in step (k) is positive and if the electronic device for receiving is in the standby mode, the electronic device for receiving reading data and calculating a size of data based on the received IRCS;

(m) determining whether the size of data is less than that of the document; and

(n) if a result of the determination in step (m) is negative, receiving the transmitted document and storing the same in the data storage module, performing an identification and a classification on the stored document based on the filename extension thereof so as to create an identifiable data, showing a result of the identification and the classification on the display module, and deactivating the IR transceiver of the electronic device for receiving prior to completion.

9. The method of claim 8, wherein if the result of the determination in step (k) is negative and if the electronic device for receiving is not in the standby mode, analyzing and processing the received IRCS.

10. The method of claim 8, wherein if the result of the determination in step (m) is positive which as an indicative of the read data being incomplete, transmits the response signal prior to analyzing and processing the received IRCS.
