US Patent 10440424 Transmission apparatus, transmission method, reception apparatus, and reception method

Connection with an apparatus with a lower standard is easily performed. A digital signal to which coding has been performed is transmitted to an external device by a differential signal through a plurality of channels via a transmission path. In this case, a digital signal to which first coding has been performed and from which clock extraction is not available is transmitted through a part of the plurality of channels, and a digital signal to which second coding has been performed and from which clock extraction is available is transmitted through the other channels of the plurality of channels. A reception side processes the digital signal received through the plurality of channels on the basis of the clock extracted from the digital signal received through any one of other channels.
