摘要： Provided is a projector that more appropriately generates white light from a laser light source and uses the white light for image display.
A white light generator of the projector has a rectangular light generating lens that generates excitation light of a rectangular shape from the blue light of a blue laser and a phosphor wheel that is coated with a phosphor that is irradiated with the excitation light to emit yellow light, wherein an arrangement is such that, when, in the phosphor wheel, a horizontal direction is set to an x-axis, a vertical direction is set to an y-axis, and an angle θ is defined such that a counterclockwise direction is positive with respect to the x-axis, a length in the vertical direction of a rectangular shape of an irradiation region is represented by v, and a length in the horizontal direction is represented by h, h v, and a center of the rectangular shape is within any one of a region having an angle of 0° or more and 45° or less, a region having an angle of 135° or more and 225° or less, and a region having an angle of 315° or more and 360° or less, or wherein an arrangement is such that h = v, and a center of the rectangular shape is within any one of a region having an angle of a region having an angle of 22.5° or more and 67.5° or less, a region having an angle of 112.5° or more and 157.5° or less, a region having an angle of 202.5° or more and 247.5° or less, and a region having an angle of 292.5° or more and 337.5° or less.

摘要： A broadcast receiving apparatus capable of exerting a function with a higher added value is provided. The broadcast receiving apparatus can receive a digital broadcasting service of a broadcasting system adopting a given media transport method, and the broadcast receiving apparatus includes: a broadcast receiving unit that receives a broadcast wave of the digital broadcasting service; a separating unit that separates at least coded program video data related to a broadcasting program, program-cooperation data, and screen layout control information, from the received broadcast wave; a video decoding unit that decodes the coded program video data to reproduce program video information; a cooperation information generating unit that interprets the program-cooperation data to generate program-cooperation information; a presentation processing unit capable of properly dividing a video display region into sub-regions based on the screen layout control information, properly placing the program video information and the program-cooperation information in the divided sub-regions, and outputting data of the video display region as video information; a display unit that displays the video information; an operation input unit to which an operation instruction of a user is input; and a control unit, and when an instruction to display a given screen is input to the operation input unit while the presentation processing unit divides the video display region into the sub-regions based on the screen layout control information, places the program video information in one of the sub-regions, places the program-cooperation information in another sub-region, and outputs the data of the video display region as the video information, the control unit controls the presentation processing unit so as to output information of the given screen as the video information without performing the division of the video display region based on the screen layout control information.
