Image display apparatus and method for operating the same

An image display apparatus comprising:

• a display;
• a user input interface configured to receive a control signal from a remote controller;
• a tuner configured to receive a broadcast signal;
• a network interface configured to transmit or receive data over a network;
• a controller configured to control the display to display a pointer according to the received control signal;
• and
• a memory including a platform configured to control data transmission or reception over the network according to the received control signal,
• wherein the platform includes an Operating System (OS) kernel and an application layer that runs on the OS kernel, the application layer including an installable or deletable application downloaded over the network and an undeletable application stored in the image display apparatus,
• wherein the display simultaneously displays a broadcast image from the broadcast signal in a first area, content received over the network and capable of being updated in a second area, and an application list including at least one of the deletable application and the undeletable application in a third area,
• wherein the platform is divided into a legacy system platform configured to run at least one application of a menu-related user interface a broadcasting guide, Bluetooth reservation digital video recording, and hot keys on the OS kernel, and a smart system platform for running at least one application of e-mail, Short Message Service (SMS), a calendar, a map, and a browser on the OS kernel,
• wherein the legacy system platform includes a driver on the OS kernel and middleware between the driver and the application layer, and
• wherein the middleware includes at least one of data broadcasting-related middleware, broadcast information-related middleware, and peripheral communication-related middleware.

A method for operating an image display apparatus, comprising:

• receiving a broadcast signal;
• transmitting an application list request to a content server or a network server;
• downloading an application list from the content server or the network server;
• receiving motion information from a remote controller;
• determining a movement of the remote controller based on the motion information;
• calculating coordinates of a pointer;
• simultaneously displaying a broadcast image from the broadcast signal in a first area, content received over the network and capable of being updated in a second area, and the application list including at least one of a deletable application and an undeletable application in a third area;
• selecting an application from the application list according to a user input;
• transmitting an application selection command corresponding to the selected application to the content server or the network server;
• downloading an application corresponding to the application selection command from the content server or the network server over a network;
• and
• installing the downloaded application,
• wherein a display area of the application list and a number of applications in the application list are varied according to a user input,
• wherein the displaying further displays the pointer representing the movement of the remote controller according to the calculated coordinates, and
• wherein when an application downloaded item is selected using the pointer, the application list is downloaded.
