Abstract:
1. A transmission device configured to transmit pixel data of one screen worth of an uncompressed image to a reception device in one direction within a valid image section that is a section obtained by removing a horizontal retrace section and a vertical retrace section from a section from one vertical synchronizing signal to the next vertical synchronizing signal, using a first differential signal, comprising: conversion device configured to convert data different from said pixel data, which is data to be transmitted, into a second differential signal made up of a first partial signal and a second partial signal, transmit said first partial signal to said reception device via a first signal line, and also output said second partial signal; first selecting device configured to select one of a first transmission signal that is a signal relating to control, and said second partial signal output from said conversion device, said second partial signal being output to said first selecting device from said first conversion device, and transmit the selected signal to said reception device via a second signal line; first control device configured to control, in the case of transmitting said first transmission signal to said reception device, said first selecting device so as to select said first transmission signal, and in the case of transmitting said second differential signal to said reception device, to control said first selecting device so as to select said second partial signal; and decoding device configured to receive a third differential signal made up of a third partial signal and a fourth partial signal, transmitted from said reception device, and decode said third differential signal to the original data, wherein said decoding device receives said third differential signal made up of said third partial signal transmitted via a third signal line, and said fourth partial signal transmitted via a fourth signal line; and wherein said transmission device further includes second selecting device configured to select one of said third partial signal, and a second transmission signal that is a signal relating to control, to be transmitted to said reception device; third selecting device configured to select one of said fourth partial signal, and a third transmission signal to be transmitted to said reception device; and second control device configured to control, in the case of transmitting said second transmission signal and said third transmission signal to said reception device, said second selecting device so as to select said second transmission signal and to transmit said second transmission signal to said reception device via said third signal line, and to control said third selecting device so as to select said third transmission signal and to transmit said third transmission signal to said reception device via said fourth signal line, and in the case of receiving said third differential signal, to control said second selecting device so as to select said third partial signal, and said decoding device so as to receive said third partial signal, and said third selecting device so as to select said fourth partial signal, and said decoding device so as to receive said fourth partial signal.
