1. A data transmission device, comprising:
a video data transmission part, transmitting video data from a first device to a second device during a video period as a timing of transmitting the video data;
a non-video data transmission part, transmitting non-video data between the first device and the second device during a video blanking period as a timing of transmitting the non-video data; and
a monitoring part, during the video blanking period, controlling the non-video data transmission part, so as to set a conflict determination period preceding an interval transmitting the non-video data as a first period in which only the first device is able to transmit a signal and, in response to presence of the signal from the first device, stop transmission of the non-video data from the second device to the first device.
