The method for transmitting a broadcasting signal according to the present invention proposes a system which can support a next generation broadcasting service in an environment that supports next generation hybrid broadcasting using a terrestrial broadcasting network and an Internet network. Further, in the environment that supports the next generation hybrid broadcasting, the present invention proposes an efficient signaling scheme which can cover both the terrestrial broadcasting network and the Internet network. ## Claims ### Claim at position 1 1-14. (canceled) ### Claim 15 A device for processing a broadcast signal, the device comprising: a tuner configured to receive the broadcast signal including a signal frame including content for a service, application signaling information for one or more applications that are related to the service and signaling information for discovering the application signaling information for the service, wherein: the signaling information including service category information representing a category of the service, the application signaling information including URL information of HTML (Hypertext Markup Language) files associated with the one or more applications; a frame parser configured to parse the signal frame; a time de-interleaver configured to time de-interleave data in the signal frame based on a TI (Time Interleaving) block; a decoder configured to decode the time de-interleaved data; a display screen configured to display application information about the one or more applications, the application information including at least one of descriptions of the one or more applications, icons representing the one or more applications, or titles of the one or more applications, wherein: in response to a selection signal of an application of the one or more applications, a controller configured to execute the application based on the application information, the display screen is further configured to display an installation button for installation of the executed application, and in response to an installation signal of the executed application, the controller is further configured to install the executed application. ### Claim 16 (depends on 15) The device of claim 15, wherein the content is delivered via one or more ROUTE sessions. ### Claim 17 (depends on 15) The device of claim 15, wherein the installation button is displayed during execution of the application. ### Claim 18 (depends on 15) The device of claim 15, wherein the display screen is further configured to display a menu for ending, updating and deleting operation of the installed application. ### Claim 19 A method of processing a broadcast signal, the method comprising: receiving the broadcast signal including a signal frame including content for a service, application signaling information for one or more applications that are related to the service, and signaling information for discovering the application signaling information for the service, wherein: the signaling information including service category information representing a category of the service, the application signaling information including URL information of HTML (Hypertext Markup Language) files associated with the one or more applications; parsing the signal frame; time de-interleaving data in the signal frame based on a TI (Time Interleaving) block; decoding the time de-interleaved data; displaying application information about one or more applications, the application information including at least one of descriptions of the one or more applications, icons representing the one or more applications, or titles of the one or more applications, wherein: in response to a selection signal of an application of the one or more applications, a controller configured to execute the application based on the application information, displaying an installation button for installation of the executed application; and in response to an installation signal of the executed application, the controller is further configured to install the executed application. ### Claim 20 (depends on 19) The method of claim 19, wherein the content is delivered via one or more ROUTE sessions. ### Claim 21 (depends on 19) The method of claim 19, wherein the installation button is displayed during execution of the application. ### Claim 22 (depends on 19) The method of claim 19, wherein the method includes: displaying a menu for ending, updating and deleting operation of the installed application. ### Claim 23 A device for processing a broadcast signal, the device comprising: an encoder configured to encode data of the broadcast signal; a time interleaver configured to time interleave the encoded data based on a TI (Time Interleaving) block; a frame builder configured to build a signal frame including the time interleaved data; and a transmitter configured to transmit the broadcast signal including the signal frame, the signal frame including content for a service, application signaling information for one or more applications that are related to the service and signaling information for discovering the application signaling information for the service, the signaling information including service category information representing a category of the service, the application signaling information including URL information of HTML (Hypertext Markup Language) files associated with the one or more applications. ### Claim 24 (depends on 23) The device of claim 23, wherein the content is delivered via one or more ROUTE sessions. ### Claim 25 (depends on 23) The device of claim 23, wherein the signaling information further includes URL information to acquire the application information and an MPD (Media Presentation Description). ### Claim 26 A method for processing a broadcast signal, the method comprising: encoding data of the broadcast signal; time interleaving the encoded data based on a TI (Time Interleaving) block; building a signal frame including the time interleaved data; and transmitting the broadcast signal including the signal frame, the signal frame including content for a service, application signaling information for one or more applications that are related to the service and signaling information for discovering the application signaling information for the service, the signaling information including service category information representing a category of the service, the application signaling information including URL information of HTML (Hypertext Markup Language) files associated with the one or more applications. ### Claim 27 (depends on 26) The method of claim 26, wherein the content is delivered via one or more ROUTE sessions. ### Claim 28 (depends on 26) The method of claim 26, wherein the signaling information further includes URL information to acquire the application information and an MPD(Media Presentation Description). ### Claim 29 (depends on 23) The device of claim 23, wherein the content is delivered via one or more ROUTE sessions. ### Claim 30 (depends on 23) The device of claim 23, wherein the signaling information further includes URL information to acquire the application information and MPD(Media Presentation Description).
