摘要： PROBLEM TO BE SOLVED: To perform channel selection, confirming contents of other station programs (competing program on a different channel) in real time by displaying video in a display area that is at least designated with a cursor in moving images among plural display areas in a multi-image mode. SOLUTION: This television receiver has a normal mode and a multi-image mode and shows at least an image in a display area that is designated by a cursor among plural display areas in the multi-image mode in a moving image. Also, it tunes into video corresponding video information in a display area which is designated to the display area instructed by the cursor at least as a condition. With such a configuration, because video of a program a user wants to view (tune in to) becomes moving images from still images, it is possible to grasp content of a desired program in real time and also to grasp rough content although it is a still image about other programs.
