Video transmission method, video reception method, video transmission apparatus, and video reception apparatus
A video transmission method according to the present disclosure includes: generating a transmission signal including, in a time series, first video data having a first luminance dynamic range and second video data having a second luminance dynamic range wider than the first luminance dynamic range; and transmitting the transmission signal generated. In the generating of the transmission signal, a signal level corresponding to a luminance value is limited to a value lower than a limit value that is predetermined, in a transition period provided for switching from one of the first video data and the second video data to the other.
1. A non-transitory computer-readable medium storing thereon a computer program for causing a computer to perform operations including:
receiving a reception 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; and
decoding the first video and the second video according to first transfer characteristics and second transfer characteristics, respectively, 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.
