a separation unit which separates video information relating to the broadcast program and application-related information from the received broadcast waves; a broadcast video decoding unit which decodes the video information relating to the broadcast program; an application acquisition unit which acquires an application on the basis of location information included in the application-related information; an application execution unit which executes the acquired application and acquires additional data from a server device; a video conversion unit which converts broadcast program video decoded by the broadcast decoding unit into high-quality video having a higher quality than the video using the acquired additional data; and a display unit which is able to display the high-quality video. ## Claims ### Claim 1 A broadcast receiving device comprising: a tuner configured to receive a broadcast wave of a digital broadcast service which is capable of executing an application in cooperation with a broadcast program; a separator configured to separate at least video information of a broadcast program and application-related information from the received broadcast wave; a video decoder configured to decode the video information of the broadcast program; a processor configured to acquire a predetermined application based on application acquired site information contained in the application-related information, execute the acquired predetermined application to acquire additional data, and execute video interpolation processing, based on the acquired additional data, on video of the broadcast program decoded by the video decoder; and a display capable of displaying at least one of the video decoded by the video decoder or the video subjected to the video interpolation processing, wherein the processor is configured to be able to acquire a predetermined application based on the application-related information received before a broadcast start time of the broadcast program, and execute the acquired predetermined application to acquire the additional data, and the processor is configured to, after start of the broadcast program, execute the video interpolation processing using at least part of the additional data acquired before the broadcast start time by the predetermined application. ### Claim 2 (depends on 1) The broadcast receiving device according to claim 1, wherein the tuner is configured to be able to further receive program information relating to a broadcast program, the processor is configured to be able to create an electronic program guide based on the received program information and display the created electronic program guide, and the processor is configured to add a mark or symbol indicating presence of the application to an area of the broadcast program in the electronic program guide where the application that can be executed in cooperation with the broadcast program exists. ### Claim 3 (depends on 1) The broadcast receiving device according to claim 1, wherein the processor is configured to acquire the predetermined application via a network based on the application acquired site information contained in the application-related information, and execute the acquired predetermined application to acquire the additional data via the network from a predetermined server. ### Claim 4 (depends on 1) The broadcast receiving device according to claim 1, wherein the processor is configured to acquire the predetermined application via the broadcast wave based on the application acquired site information contained in the application-related information, and execute the acquired predetermined application to acquire the additional data via the broadcast wave. ### Claim 5 (depends on 1) The broadcast receiving device according to claim 1, wherein the additional data is differential data for interpolating a frame of video of the broadcast program decoded by the video decoder, and the processor executes, as the video interpolation processing, processing of interpolating a frame of the decoded video of the broadcast program using the additional data. ### Claim 6 (depends on 1) The broadcast receiving device according to claim 1, wherein the additional data is differential data for interpolating a pixel of video of the broadcast program decoded by the video decoder, and the processor executes, as the video interpolation processing, processing of interpolating a pixel of the decoded video of the broadcast program using the additional data. ### Claim 7 (depends on 1) The broadcast receiving device according to claim 1, wherein the additional data is differential data for interpolating a quantization bit rate of video of the broadcast program decoded by the video decoder, and the processor executes, as the video interpolation processing, processing of interpolating a quantization bit rate of the decoded video of the broadcast program using the additional data. ### Claim 8 (depends on 1) The broadcast receiving device according to claim 1, wherein the processor determines, based on the information contained in the application-related information, whether the broadcast receiving device is capable of executing the video interpolation processing using the additional data and/or displaying on the display, and acquires the application in a case where the processor determines is capable of executing and/or displaying. ### Claim 9 (depends on 1) The broadcast receiving device according to claim 1, wherein the processor determines whether a user of the broadcast receiving device has paid a charge for use of service to a predetermined service provider, and in a case where the processor determines that the user has paid, the processor executes the video interpolation processing using the additional data to display the video subjected to the video interpolation processing on the display. ### Claim 10 (depends on 1) The broadcast receiving device according to claim 1, further comprising: a digital interface communicable with an external device, wherein the processor stores the acquired additional data in a storage as the external device coupled to the digital interface. ### Claim 11 (depends on 10) The broadcast receiving device according to claim 10, wherein the processor encrypts the additional data acquired before the broadcast start time of the broadcast program at least before the start of the broadcast program to store the encrypted additional data in the storage coupled to the digital interface.
