<P>PROBLEM TO BE SOLVED: To reproduce video images by a correct aspect ratio even when information with an incorrect aspect ratio is transmitted in a video output device conforming to a specification for transmitting and receiving the information of video signals. <P>SOLUTION: A television 1 includes an HDMI_RX chip 2, a sound processing part 30, a display part 52 and a video processing part 50. The HDMI_RX chip 2 receives video signals, sound signals and the information (M value) of the aspect ratio added thereto from a DVD player 101. The HDMI_RX chip 2 records the information of the aspect ratio in a first register 21. An MPU 6 determines whether or not a value corresponding to a concrete aspect ratio is input to the HDMI_RX chip 2 and whether or not the received information of the aspect ratio corresponds to the resolution of the received video signal on the specification. When any of the determinations is negative, the input aspect ratio is not used and the aspect ratio determined on the basis of the resolution of the received video signal is set to a second register 51. <P>COPYRIGHT: (C)2009,JPO&INPIT |
