A method for providing a User Interface, UI, in a television, the method comprising: receiving (S901-S903; S1001) a request for provision of the UI; collecting (S904; S1002) information for configuring the requested UI; classifying (S905; S1003) the collected information according to a first criterion so as to generate a plurality of pages; and displaying (S907; S1005) the generated pages according to a second criterion so as to form a multilayer UI as the requested UI, characterized in that the formed multilayer UI is received from a formatter which further generates a synchronization signal (Vsync) in order to perform synchronization when a user views 3D image data with glasses, wherein the formatter outputs the synchronization signal to an infrared, IR, emitter included in the glasses, the method further comprising: receiving (S908; S1006) a request signal for selecting a specific layer; changing the second criterion corresponding to the request signal; and rearranging the layers according to the second criterion so as to form an individual UI, wherein the first criterion and the second criterion are set by the user or are automatically set according to a predetermined criterion and include at least one of a date, a genre, a time, a favorite and a user ID, wherein information about each layer configuring the multilayer UI is divided and provided according to each of different users using the television, wherein an uppermost-level layer provides a favorite channel information of a first user and a next layer provides a favorite channel information of a second user, wherein the favorite channel information includes information for identifying whether the favorite channel information is information about a terrestrial wave, a cable or an internet protocol television, IPTV, wherein the favorite channel information is provided along with program information of a virtual channel. receiving (S901-S903; S1001) a request for provision of the UI; collecting (S904; S1002) information for configuring the requested UI; classifying (S905; S1003) the collected information according to a first criterion so as to generate a plurality of pages; and displaying (S907; S1005) the generated pages according to a second criterion so as to form a multilayer UI as the requested UI, characterized in that the formed multilayer UI is received from a formatter which further generates a synchronization signal (Vsync) in order to perform synchronization when a user views 3D image data with glasses, wherein the formatter outputs the synchronization signal to an infrared, IR, emitter included in the glasses, the method further comprising: receiving (S908; S1006) a request signal for selecting a specific layer; changing the second criterion corresponding to the request signal; and rearranging the layers according to the second criterion so as to form an individual UI, receiving (S908; S1006) a request signal for selecting a specific layer; changing the second criterion corresponding to the request signal; and rearranging the layers according to the second criterion so as to form an individual UI, wherein the first criterion and the second criterion are set by the user or are automatically set according to a predetermined criterion and include at least one of a date, a genre, a time, a favorite and a user ID, wherein information about each layer configuring the multilayer UI is divided and provided according to each of different users using the television, wherein an uppermost-level layer provides a favorite channel information of a first user and a next layer provides a favorite channel information of a second user, wherein the favorite channel information includes information for identifying whether the favorite channel information is information about a terrestrial wave, a cable or an internet protocol television, IPTV, wherein the favorite channel information is provided along with program information of a virtual channel.
