Abstract:
1. A method for controlling an image display apparatus, comprising: determining a type of a video signal included in an input signal; determining whether three-dimensional (3D) format information is included in the input signal, if the video signal is a 3D video signal; requesting 3D format information about the video signal to a server that stores 3D format information, if the input signal does not include the 3D format information about the video signal; processing, upon receipt of 3D format information from the server in response to the 3D format information request, the video signal according to the 3D format information and displaying a 3D image based on the processed video signal; displaying a window for determining whether to retry the receipt of the 3D format information, if the 3D format information is not received from the server; simultaneously displaying a plurality of 3D format items for the 3D video signal when the 3D format information is not received from the server after retrying the receipt of the 3D format information; and processing the video signal according to predetermined 3D format information and displaying a 3D image based on the processed video signal, the predetermined 3D format information corresponding to a selected 3D format item among the plurality of 3D format items by a 3D format selection command input to the image display apparatus, wherein the 3D format information requesting comprises collecting title information regarding a content including the 3D video signal, and transmitting the collected title information to the server, wherein the 3D format information from the server matches to the title information included in the received 3D format request signal, wherein the 3D format selection command input is performed by using a pointer Corresponding to a signal transmitted by a remote controller, and wherein the plurality of 3D format items includes a first 2D image including a left-eye image and a right-eye image which are vertically arranged and a second 2D image including a left-eye image and a right-eye image which are horizontally arranged.
