Abstract

The present invention provides a universal serial bus (USB) display unit comprising a microprocessor with a USB interface, where the USB interface is adapted to receive video data from a first source, and a video decoder adapted to receive other video data from a second source. The USB unit also comprises a field-programmable gate array (FPGA) adapted to process the video data and the other video data, a memory adapted to store the processed video data and the processed other video data, and a display adapted to contemporaneously display the processed video data and the processed other video data. The microprocessor is adapted to transmit the processed other video data to the first source via the USB interface which is adapted to receive audio data from the first source. The USB unit further comprises an audio circuit adapted to provide the audio data via the FPGA, where the video decoder, the audio circuit, the microprocessor, the display, and the memory are operably coupled to the FPGA.
