US 12,256,171 B2 · Data transmission device and data transmission method

Abstract

A data transfer device includes: a video transmission circuit 24, transmitting video data from a first device 10 to a second device 50 during a video period as a timing of transmitting the video data; a transmission part 32, 72, transmitting non-video data between the first device 10 and the second device 50 during a video blanking period as a timing of transmitting the non-video data; and a monitoring part 30, 70, during the video blanking period, controlling the transmission part 32, 72 to stop transmission of the non-video data from the second device 50 to the first device 10 in response to presence of a signal from the first device 10 and stop transmission of the non-video data from the first device 10 to the second device 50 in response to presence of a signal from the second device 50.

Dependent claims

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.
