Data transmission apparatus and method

摘要

A data transmission apparatus and method are provided. The data transmission apparatus includes a USB interface unit that communicates with an external device using a TCP/IP packet, and a control unit that controls the USB interface unit to convert data into a TCP/IP packet along one of a plurality of transmission paths according to a priority of data processing and transmits the TCP/IP packet. Accordingly, data (e.g., control data) requiring urgent processing may be timely transmitted to an external device regardless of traffic of the data transmission apparatus.

1. A data transmission apparatus, comprising:
a universal serial bus (USB) interface unit that communicates with an external device using a transmission control protocol/Internet protocol (TCP/IP) packet; and a control unit that controls the USB interface unit to convert data into a TCP/IP packet along one of a plurality of transmission paths according to a priority of data processing and transmits the TCP/IP packet, wherein upon first data having a high priority of data processing, the control unit converts the first data into a TCP/IP packet along a first transmission path and transmits the TCP/IP packet to the external device through the USB interface unit, and upon second data having a low priority of data processing, the control unit converts the second data into a TCP/IP packet along a second transmission path and transmits the TCP/IP packet to the external device through the USB interface unit, wherein the control unit emulates a different virtual MAC address to the first transmission path and the second transmission path.
