Stereoscopic video playback device and stereoscopic video display device

A stereoscopic video playback method comprising the steps of:

• decoding stream data into a pair of left-view and right-view video planes;
• alternatively outputting the pair of video planes in a period where no image plane that includes at least one of an OSD and a pop-up display is generated;
• generating a pair of left-view and right-view image planes that have the OSD or the pop-up display at different display locations in a horizontal direction, and alternately outputting the pair of image planes, the display locations to be determined from a depth of the OSD or the pop-up display to be perceived;
• repeatedly outputting either of the pair of video planes in a period where the pair of image planes are outputted;
• and
• combining a video plane and an image plane into a single frame and outputting the frame each time the video plane and the image plane are outputted.

A computer program for causing a stereoscopic video playback device to perform the steps of:

• decoding stream data into a pair of left-view and right-view video planes;
• alternatively outputting the pair of video planes in a period where no image plane that includes at least one of an OSD and a pop-up display is generated;
• generating a pair of left-view and right-view image planes that have the OSD or the pop-up display at different display locations in a horizontal direction, and alternately outputting the pair of image planes, the display locations to be determined from a depth of the OSD or the pop-up display to be perceived;
• repeatedly outputting either of the pair of video planes in a period where the pair of image planes are outputted;
• and
• combining a video plane and an image plane into a single frame and outputting the frame each time the video plane and the image plane are outputted.

A stereoscopic video display device comprising:

• a video signal receiving unit operable to receive a video signal, extract a pair of left-view and right-view video frames from the video signal, and output the pair of video frames in either a 3D display mode or a pseudo 2D display mode according to an instruction, the 3D display mode for alternately outputting the pair of video frames, and the pseudo 2D display mode for repeatedly outputting either of the pair of video frames;
• a display unit including a display panel and operable to adjust brightness of the display panel in units of pixels according to video frames outputted from the video signal receiving unit, thus reproducing an image represented by the video frames on the display panel;
• an OSD plane generation unit operable to generate a pair of left-view and right-view OSD planes having an OSD at different display locations in a horizontal direction, and alternately output the pair of OSD planes, the display locations to be determined from a depth of the OSD to be perceived;
• a pseudo 2D display control unit operable to instruct the video signal receiving unit to operate in the 3D display mode in a period where the OSD plane generation unit does not output the pair of OSD planes, and instruct the video signal receiving unit to operate in the pseudo 2D display mode in a period where the OSD plane generation unit outputs the pair of OSD planes;
• and
• an adder unit operable to combine and output a video frame with an OSD plane each time the video signal receiving unit outputs a video frame and the OSD plane generation unit generates an image plane.
