Japanese Patent JP6956354

B2

A video signal output apparatus (10) includes: an outputter (104) that outputs a video signal and a first audio signal to each of output apparatuses; a receiver (105) that receives a second audio signal generated as a result of each of the output apparatuses performing audio signal processing on the first audio signal output by the outputter (104); an synchronization information obtainer (106) that obtains synchronization information indicating a time difference between a time required for video signal processing and a time required for the audio signal processing by each of the output apparatuses; a delay calculator (107) that calculates a delay time for reducing a time difference between respective timings of displaying video by the output apparatuses, using a timing at which the receiver (105) receives the second audio signal from each of the output apparatuses and the synchronization information obtained by the synchronization information obtainer (106); and a delayer (103) that delays the video signal and the first audio signal to be output by the outputter (104), by the delay time calculated by the delay calculator (107).
