WebSpaceWire to transmit image data the camera captured and display it on some widget. To do this, the 1 This work is supported by NNSFC Grant #60873006 and Beijing MCESTD Grant #KM 200910028019. SpaceWire's modulation and data formats generally follow the data strobe encoding - differential ended signaling (DS-DE) part of the IEEE Std 1355-1995. SpaceWire utilizes asynchronous communication and allows speeds between 2 Mbit/s and 200 Mbit/s, with initial signalling rate of 10Mbit/s. DS-DE is well-favored because it describes modulation, bit formats, routing, flow control, and error detection in hardware, with little need for software.
