Abstract:
1. A transmission apparatus for transmitting a video signal through a transmission path, comprising: a decoder to decode a compressively coded signal to output picture signals, including a base-band luminous signal and base-band color different signals, and a control signal which is generated based on the compressively coded signal; an encoder to time-divisionally multiplex the picture signals in a video period and the control signal in a retrace period, thereby to encode the picture signals and the control signal into transmission path signals suited to the transmission path; an I2C controller to control an I2C (Inter IC control) signal sent to the transmission apparatus from a reception apparatus; and a CPU to control the wherein the decoder is controlled by the CPU so as to output the picture signals which are displayable in reception apparatus, on the basis of reception apparatus information included in the I2C signal that is received from the reception apparatus.
