Document Type and Number:
WIPO Patent Application WO/2023/238907
Kind Code:
A1
Abstract:
Provided is a media transmission system, wherein a media sending device 1 includes a video signal reception circuit 111 that receives a video signal generated while associated with the timing of an alignment point, a packetization circuit 112 that converts the video signal into a plurality of packets on a frame-by-frame basis, a time stamp giving circuit 113 that gives, to each packet, a time stamp of the timing of the alignment point at the time of generation, and an IP signal sending circuit 114 that sends each packet as an IP signal, and a media reception device 2 includes an IP signal reception circuit 211 that receives the packet, a depacketization circuit 212 that reproduces a video signal frame from the packet, an offset control circuit 213 that outputs the reproduced frame at an output timing obtained by adding an offset to the alignment point of the time stamp, and a video signal sending circuit 214 that output the frame outputted from the offset control circuit 213.
