Image signal processing apparatus, image signal processing method, program, and image signal processing system

An image signal processing method, comprising:

• receiving a display signal including an image signal containing both a two-dimensional image and a three-dimensional image, and region information defining in a predetermined unit a first region to display the two-dimensional image, a second region to display the three-dimensional image, and including data to control activation or deactivation of the first or second region and timing information defining a time associated with the received display signal;
• separating the image signal, the region information, and the timing information from the received display signal;
• generating first display control information for controlling rendering positions of the first region and the second region in the image signal according to the separated region information, a control signal according to the separated timing information, and second display control information for selectively displaying a three-dimensional image in a region corresponding to the rendering position of the second region on the display screen based on the separated region information;
• transmitting the first display control information, the control signal, and the second display control information based on a comparison of the timing information and a reference check signal;
• generating a display image signal indicating where the first region and the second region are to be displayed according to the first display control information generated in the generating step and the image signal separated in the separating step;
• and
• outputting the display image signal in synchronization with transmission of the second display control information according to the control signal.
