Patent number: 8754930Abstract: Provided is a video transmission device that includes: a transmission signal output portion that outputs a video signal that causes two-dimensional video or three-dimensional video to be displayed, an audio signal that causes audio to be output, and a control signal including information relating to the video signal and the audio signal; and a control portion that controls content of the control signal output from the transmission signal output portion. When the video signal switches from three-dimensional video to two-dimensional video, the control portion does not stop output of the video signal from the transmission signal output portion, and controls the transmission signal output portion such that information indicating that the video signal output from the transmission signal output portion has switched to two-dimensional video is included in information indicating that the video signal is three-dimensional video that is output from the transmission signal output portion.Type: GrantFiled: January 7, 2011Date of Patent: June 17, 2014Assignees: Sony Corporation, Sony Computer Entertainment Inc.Inventors: Takehiko Saito, Koichi Takenaka
