Abstract: A system and method are provided for capturing a high resolution, high frame rate video using a Universal Serial Bus (USB) port. Generally, the method involves transmitting a High-Definition Multimedia Interface (HDMI) video including a number of video frames from a HDMI-source. Receiving the HDMI video and buffering and splitting each one of the video frames into a plurality of split video frames. Each of the split video frames is converted into a number of USB data packets. USB data packets from each of the split video frames are then interleaved to form a stream of USB data packets. The stream of USB data packets is coupled to a host system, which executes a program to stitch the USB data packets back together to reassemble each of the video frames, and order the video frames to restore or recreate the HDMI video.
