Data transmission device, system and method using the same

A data transmission system communicating between an external electronic apparatus and an external monitor and for wirelessly receiving and transmitting multimedia data generated from the electronic apparatus executing a multimedia file correlated to said multimedia data to be transmitted to the monitor for displaying said multimedia data on the external monitor, said data transmission system comprising:

• an execution-end data transmission device electrically connected to the electronic apparatus comprising:
• an input interface connecting to the electronic apparatus to receive and transmit the multimedia data;
• a first multimedia processing unit electrically connected to the input interface for receiving, encoding and compressing the multimedia data;
• and a first wireless transmission module electrically connected to the first multimedia processing unit for wirelessly receiving and transmitting the encoded and compressed multimedia data;
• a display-end data transmission device in communication with the execution-end data transmission device and electrically connected to the external monitor comprising:
• a second wireless transmission module for wirelessly receiving the multimedia data transmitted via said first wireless transmission module of the execution-end data transmission device;
• a second multimedia processing unit electrically connected to the second wireless transmission module for receiving the multimedia data and decompressing and decoding the multimedia data;
• and an output interface electrically connected to the second multimedia processing unit and coupled to the monitor for transmitting and converting the multimedia data in accordance with a display specification of the external monitor for displaying said multimedia data, wherein the execution-end data transmission device further comprises a receiver electrically connected to the first multimedia processing unit such that the execution-end data transmission device receives a command stream sent from the display-end data transmission device wirelessly;
• and wherein the execution-end data transmission device converts the command stream received by the receiver thereof such that the command stream is transmitted to and processed by the electronic apparatus, and wherein the command stream transmitted adapts to a Bluetooth profile, the data transmission system further comprising an external controller, and the external controller is wirelessly transmitting the command stream through Bluetooth.

A data transmission method for wirelessly transmitting a multimedia data from an electronic device to a monitor to receive and display said multimedia data thereon;

• wherein said electronic device and the monitor are coupled to an execution-end and a display-end data transmission devices respectively such that the multimedia data is transmitted and communicated between said execution-end and display-end data transmission devices, said method comprising:
• wirelessly receiving the multimedia data via a second wireless transmission module of the display-end data transmission device;
• decompressing and decoding the multimedia data at a second multimedia processing unit of the display-end data transmission device;
• converting and transmitting the multimedia data in accordance with a display specification of the monitor for displaying said multimedia data;
• generating the multimedia data for transmitting from the execution-end data transmission device of the electronic apparatus to the display-end data transmission device coupled to the monitor;
• encoding and compressing the multimedia data at a first multimedia processing unit of the execution-end data transmission device;
• and wirelessly transmitting the multimedia data from a first wireless transmission module of the execution-end data transmission device to the display-end data transmission device.
