Interconnecting system, video signal transmitter and video signal receiver for transmitting an N-symbol data signal

A video signal transmitter for transmitting a stream of image data signals over an error prone wired connection to a video signal receiver, the video signal transmitter comprising:

• a parallel interface comprising at least N data terminals each capable of outputting a signal comprising one data symbol;
• and
• a line scrambler having N output terminals each capable of outputting a signal comprising one data symbol, wherein
• the parallel interface is provided for being coupled to a parallel bus having at least N data signal lines,
• every output terminal of the line scrambler is fixedly coupled to one different data terminals of the parallel interface,
• the line scrambler is configured to accept at least a color component signal of a pixel of the image data, wherein the color component signal comprises an N-symbol data signal having a sequence of N data symbols in a predefined order, and to output a permuted sequence of data symbols at the N output terminals of the line scrambler, and
• the one or more data symbols of the N-symbol data signal, which have the lowest significance levels, are output at the one or more output terminals of the line scrambler, which are coupled to one or more defective data signal lines detected by feedback fault indication transmitted by the video signal receiver.

A video signal receiver for receiving a stream of image data signals over an error prone wired connection to a video signal transmitter, the video signal receiver comprising:

• a parallel interface comprising at least N data terminals;
• and
• a line de-scrambler having N input terminals each capable of accepting a signal comprising one data symbol, wherein
• the parallel interface is provided for being coupled to a parallel bus having at least N data signal lines,
• every input terminal of the line de-scrambler is fixedly coupled to one different data terminals of the parallel interface,
• the line de-scrambler is configured to accept the permuted sequence of data symbols at its input terminal, to restore a predefined order of the data symbols from the permuted sequence of data symbols, and to output the restored N-symbol data signal comprising the sequence of data symbols in the predefined order, and
• the restored N-symbol data signal comprises at least a color component signal of a pixel of the image data.

An interconnect system for transmitting a stream of image data signals formed of N-symbol data signals over an error prone wired connection, the system comprising:

• a video signal transmitter with a test signal generator;
• a video signal receiver with a defect detector;
• and
• a parallel bus having at least N data signal lines, each data signal line capable of transmitting a signal comprising one data symbol, wherein
• the test signal generator is configured to assert one or more predetermined test signals on the at least N data signal lines of the parallel bus, and
• the defect detector is configured to detect the one or more predetermined test signals in order to detect an erroneous data signal transmission on one or more defective data signal lines based on the detected one or more predetermined test signals, and to issue a fault indication indicative of the one or more detected defective data signal lines.
