1. A video transmission method comprising:
generating a transmission signal including, in a time series, a first video having a first luminance dynamic range and a second video having a second luminance dynamic range wider than the first luminance dynamic range, the first video and the second video being to be decoded according to first transfer characteristics and second transfer characteristics, respectively; and
transmitting the transmission signal generated, wherein
a first signal level of the first video converted according to the first transfer characteristics is substantially the same as a second signal level of the second video converted according to the second transfer characteristics in a transition period in which a played video is switched from one of the first video and the second video to the other of the first video and the second video.
