  • AUDIO-VISUAL SYSTEM, REPRODUCING APPARATUS, AND DISPLAY DEVICE
    Publication number: 20080284913
    Abstract: The TV receiver as a display device has a drawing generation unit for generating display side drawing data of drawn picture according to a display format for on-screen display, and a reproducing apparatus has a drawing generation unit for generating reproduction side drawing data of drawn picture according to a display format for display on the TV receiver. The drawing generation unit receives the display format information of the drawing generation unit through a connection cable, and generates reproduction side drawing data of display format based on the received display side display format information. The reproducing apparatus supplies the contents data including the generated reproduction side drawing data to the TV receiver through the connection cable, and the TV receiver presents the drawn picture based on the supplied reproduction side drawing data.
