REPRODUCTION DEVICE AND REPRODUCTION METHOD
When a reproduction device and a display device are separated, there is the risk that it will not be possible to appropriately overly menu images or the like on a 3D video signal in the reproduction device. This reproduction method, which outputs a video signal generated in a reproduction device to a display device, has: a step for reproducing a video signal; a step for generating image information to be superimposed on the reproduced video signal; a step for superimposing the generated image information on the reproduced video signal; a step for outputting the video signal to which the image information has been superimposed; a step for reading information relating to the display device from the display device; and a step for acquiring information relating to the state of the display device from the display device. The configuration is such that the method of superimposing the image information on the video signal is altered on the basis of the acquired information relating to the state of the display device and the read information relating to the display device.
1 . A reproduction device that outputs a video signal to a connected display device, the reproduction device comprising:
a reproduction unit that reproduces a video signal;
an image information generation unit that generates image information to be superimposed on the video signal reproduced by said reproduction unit;
a superimposition unit that superimposes the image information on the video signal, the video signal reproduced by said reproduction unit, the image information generated by said image information generation unit;
an output unit that outputs the video signal on which the image information is superimposed by said superimposition unit;
a reading unit that reads information about the display device from the connected display device; and
a control processing unit that acquires information about a state of the display device from the connected display device wherein
said superimposition unit changes a method for superimposing the image information on the video signal based on the information about the display device read by said reading unit and on the information about the state of the display device acquired by said control processing unit.
2 . The reproduction device according to claim 1 wherein
the information about the display device read by said reading unit includes information indicating whether or not the display device can display a 3D video.
3 . The reproduction device according to claim 1 wherein
the information about the state of the display device acquired by said control processing unit includes information indicating whether or not 3D video display setting is specified for the display device.
4 . The reproduction device according to claim 1 wherein
if the video signal includes a left-eye video and a right-eye video, the information about the display device, read by said reading unit, indicates that the display device can display a 3D video, and the information about the state of the display device, acquired by said control processing unit, indicates that the display device is in a state in which a 3D video is displayed,
said superimposition unit superimposes the image information on each of the left-eye video and the right-eye video of the video signal.
5 . A reproduction method that outputs a video signal, reproduced by a reproduction device, to a display device, the reproduction method comprising the steps of:
reproducing a video signal;
generating image information to be superimposed on the reproduced video signal;
superimposing the generated image information on the reproduced video signal;
outputting the video signal on which the image information is superimposed;
reading information about the display device from the display device; and
acquiring information about a state of the display device from the display device wherein
a method for superimposing the image information on the video signal is changed based on the information about the display device that is read and on the information about the state of the display device that is acquired.
6 . The reproduction method according to claim 5 wherein
the information about the display device includes information indicating whether or not the display device can display a 3D video.
7 . The reproduction method according to claim 5 wherein
the information about the state of the display device includes information indicating whether or not 3D video display setting is specified for the display device.
8 . The reproduction method according to claim 5 wherein
if the video signal includes a left-eye video and a right-eye video, the information about the display device indicates that the display device can display a 3D video, and the information about the state of the display device indicates that the display device is in a state in which a 3D video is displayed,
the image information is superimposed on each of the left-eye video and the right-eye video of the video signal.
