Abstract: There is a problem in that, conventionally, an OSD of a channel sign is displayed in a uniform pattern regardless of any switching operations. Thus it may be difficult for a user to intuitively grasp which switching operation causes a screen display based only on information on the screen, in the case where the user watches a TV screen but not the remote controller. To solve this problem, an AV device is provided which displays an animation of the channel sign from bottom to top in the case where an up key of a broadcast reception channel is operated, for example, and a function for displaying the animation of the channel sign from right to left in the case where an external input (input channel) switching operation is performed so that the user is capable of intuitively grasping the content of the operation.
