Video transmitter, video transmission method, and program device

摘要

A video transmitter includes: a video resolution acquisition unit that acquires a resolution of a video signal; a wireless communication unit wirelessly transmitting the video signal and wirelessly receiving, from a terminal wirelessly receiving a video signal wirelessly transmitted, a received radio wave intensity and a minimum reception sensitivity at a time when wirelessly receiving the video signal; and a communication rate setting unit that sets a communication rate at a time when wirelessly transmitting the video signal according to the acquired resolution of the video signal. The wireless communication unit includes a transmission output control unit that controls the wireless communication unit to wirelessly transmit the video signal at the communication rate set by the communication rate setting unit and controls a wireless transmission output of the wireless communication unit to suppress a difference between the radio wave intensity and the minimum reception sensitivity.

主权项

1. A video transmitter comprising:
a video resolution acquisition unit configured to acquire a resolution of a video signal; a wireless communication unit including an antenna, the wireless communication unit wirelessly transmitting the video signal and wirelessly receiving, from a terminal, which wirelessly receives a video signal that has been wirelessly transmitted, a received radio wave intensity and a minimum reception sensitivity at a time when wirelessly receiving the video signal; and a communication rate setting unit configured to set a communication rate at a time when wirelessly transmitting the video signal according to the resolution of the video signal that has been acquired, wherein the wireless communication unit includes a transmission output control unit, the transmission output control unit controlling the wireless communication unit to wirelessly transmit the video signal at the communication rate that has been set by the communication rate setting unit, the transmission output control unit controlling a wireless transmission output of the wireless communication unit to suppress a difference between the radio wave intensity, which has been received, and the minimum reception sensitivity, which has been wirelessly received by the wireless communication unit, when the set communication rate is less than a first predetermined value and the difference is equal to or greater than a second predetermined value.
