Title: VIDEO TRANSMISSION METHOD, VIDEO RECEPTION METHOD, VIDEO TRANSMISSION DEVICE, AND VIDEO RECEPTION DEVICE
Abstract:
In a video transmission method of the present disclosure, a transmission signal which includes, in time series, first video data having a first luminance dynamic range and second video data having a second luminance dynamic range that is broader than the first luminance dynamic range is generated, and the generated transmission signal is transmitted. In the generation of the transmission signal, during a transition period when switching occurs from one of the first video data and the second video data to the other, a level of the signal corresponding to the luminance value is restricted to a value lower than a predetermined limit value.
