Digital communication apparatus employing digital communication cable for mobile communication terminal and method thereof

Abstract

Disclosed is a digital communication apparatus employing digital communication cable for mobile communication terminal and method thereof. The apparatus includes: an external memory slot connecting with the external terminal through the digital communication cable; a parallel connection communication part processing the data in parallel; a series connection communication part performing the series connection process on the data; a path selection part switching one of the parallel connection communication part and the series connection communication part with selectivity about the corresponding control signals based on the communication mode of the external terminal and selecting the data path; a signal conversion part, converting the analog signals of the output data about the path selection part into the digital signals, and converting the digital signals with the data transferred to the path selection part into the analog signals to output; a control unit controlling the integral action based on the data communication mode, and outputting the control signals according to the communication mode of the external terminal and changing the data process path; a memory for storing the transmitting / receiving data through the data communication mode.

Description

technical field [0001] The present invention relates to a mobile communication terminal, in particular to a data communication device and method for a mobile communication terminal using a data communication cable. Slots and slots for other terminals, enabling data communication operations between the aforementioned terminals. Background technique [0002] In addition to the basic voice call function, the recently released mobile communication terminal also basically includes functions such as camera function and MP3 music player. However, due to the limited size of the built-in memory in the mobile communication terminal, a large amount of corresponding data (music files, image files, etc.) cannot be stored. For this reason, external memory card slot (memory card socket) is set in the mobile communication terminal of prior art, and external memory card (SD, MMC, mini SD etc.) is installed in above-mentioned external memory card slot and increases data storage capacity , w...

AI Technical Summary

Problems solved by technology

[0005] However, in the mobile communication terminals of the prior art, the data exchange between the terminals can only be carried out through the data communication cable connected to the above-mentioned 24-pin plug, so that it is impossible to realize multitasking operations such as outputting photos while performing data exchange.

Moreover, due to the use of USB type data cables, the data processing speed will be slower than the parallel processing method
