Abstract: An extension apparatus for a universal serial bus (USB) interface includes a transmitting device, a receiving device and an electrical signal network cable. The transmitting device includes the following elements: a first packet-processing unit to receive a first interface packet and generate an original data accordingly, a first buffering unit to temporarily store the original data, and a first data-converting unit to generate and output a network packet signal based on the original data. The receiving device includes the following elements: a second data-converting unit to receive the network packet signal and generate the original data accordingly, a second buffering unit to temporarily store the original data, and a second packet-processing unit to receive the original data and generate the first interface packet. The electrical signal network cable is electrically coupled between the transmitting device and the receiving device to transmit the network packet signal.

Abstract: A method for increasing compatibility of DisplayPort includes: providing a first source device, a second source device, a controller, and a sink device, wherein the first source device is connected to the controller; the first source device transmitting a first image signal to the sink device via a main link for displaying the first image signal on the sink device; causing the controller to disconnect from the first source device and connect to the second source device; executing a simulation process to generate a DC level variation on an auxiliary channel between the controller and the sink device; the second source device transmitting auxiliary data to the sink device; the sink device transmitting link data back to the second source device; and the second source device transmitting a second image signal to the sink device via a second main link for displaying the second image signal on the sink device.
