<p>PURPOSE:To minimize the checking time and error response awaiting time of data by making a re-sending data unit into a small block unit and making the checking unit of the data into respective words. CONSTITUTION:Line data DD introduced to a line buffer memory 58 for a pixel clock CP are transferred to a code checking controller 56 and it is decided for the rise edge of a pixel clock CP whether the data are correctly transmitted or not. When a transmitting error is present in line data DD0, an error response signal is transmitted to a re-sending controller 42 in a re-sending sending device 32. A system controller 40 adds the signal of the effect that the line data DD to be sent next are actually the same as the line data DD0 during the transmission, as an LO level signal and re-sends the line data DD0 transmitted previously.</p> |
