摘要:
A video output apparatus includes an attribute information acquisition unit that acquires attribute information of a display apparatus through a communication unit, a determination unit that determines whether to superimpose additional information on a video signal based on the attribute information of the display apparatus acquired by the attribute information acquisition unit, an output unit that superimposes the additional information extracted by an additional information extraction unit on the video signal output from a video decoding unit and outputs the additional information superimposed on the video signal to the communication unit if the determination unit determines to superimpose the additional information on the video signal, and outputs the video signal output from the video decoding unit to the communication unit without superimposing the additional information on the video signal if the determination unit determines not to superimpose the additional information on the video signal.
