Port extension apparatus
Port extension apparatus for providing better usage and utilization efficiency ports of end-user devices are disclosed. Port extension apparatus includes at least a main port module for connection to end-user device, first data port module, data transmission control module, second data port module, and video port module. When a to-be-connected device connects to the first data port module, the first data port module and the main port module form a transmission path enabling data transmission between the to-be-connected device and the end-user device. When the to-be-connected device connects to the second data port module, the data transmission control module controls the data transmission between the to-be-connected device and the end-user device. When the to-be-connected device connects to the video port module, the data transmission control module receives the to-be-displayed information from the end-user device and transmits to the to-be-connected device to display.
1. A port extension apparatus for extending ports of an end-user device comprising:
a main port module for connecting to an end-user device, the main port module having first and second port units;
a first data port module operatively connecting to the first port unit;

a second data port module operatively connecting to a second data transmission port of the data transmission control module; and
a video port module operatively connecting to a third data transmission port of the data transmission control module; wherein
when a to-be-connected device connects to the first data port module, the first data port module and the main port module form a transmission path enabling data transmission between the to-be-connected device and the end-user device;
when a to-be-connected device connects to the second data port module, the data transmission control module controls data transmission between the to-be-connected device and the end-user device; and
when a to-be-connected device connects to the video port module, the data transmission control module receives the to-be-displayed information from the end-user device to the to-be-connected device to display.
2. The port extension apparatus as described in claim 1 , further comprising:
