Output video data is obtained by performing mix processing such as dissolve and wipe on first video data and second video data. Before performing the mix processing, a format of the first video data and the second video data is made the same as a video format handled by the mixing unit. Further, after performing the mix processing, a format of the output video data is made the same as an output video format. ## Claims ### Claim 1 A video data processing device comprising: a video data input unit that inputs first video data and second video data; a mixing unit that mixes the first video data and the second video data inputted by the video data input unit and obtains output video data; a first video format conversion unit that is arranged between the video data input unit and the mixing unit and that makes a video format of the first video data and the second video data inputted into the mixing unit the same as a video format handled by the mixing unit; and a second video format conversion unit that is arranged on an output side of the mixing unit and that makes a video format of the output video data outputted from the mixing unit the same as an output video format. ### Claim 2 (depends on 1) The video data processing device according to claim 1, wherein the first video data and the second video data are respectively video data of a first video format where the number of vertical pixels is a first value and the number of horizontal pixels is a second value or a second video format where the number of vertical pixels is the first value and the number of horizontal pixels is a third value, the mixing unit handles the first video format or the second video format, and the output video format is the first video format or the second video format. ### Claim 3 (depends on 2) The video data processing device according to claim 2, wherein the first value is 2160, the second value is 3840, and the third value is 4096. ### Claim 4 (depends on 3) The video data processing device according to claim 3, wherein the video data is four-divided 4K mode video data. ### Claim 5 (depends on 3) The video data processing device according to claim 3, wherein the mixing unit mixes the first video data and the second video data by wipe. ### Claim 6 (depends on 5) The video data processing device according to claim 5, wherein when the mixing unit handles the first video format, wipe control transits within a range of 3840-size having a shape of 16:9. ### Claim 7 (depends on 5) The video data processing device according to claim 5, wherein when the mixing unit handles the second video format, wipe control transits within a range of 3840-size having a shape of 16:9, transits within a range of 4096-size having a shape of 16:9, or transits within a range of 4096-size having a shape of 17:9. ### Claim 8 (depends on 1) The video data processing device according to claim 1, further comprising: a control unit that controls conversion operation on the first video data and the second video data in the first video format conversion unit on the basis of video format information of each of the first video data and the second video data. ### Claim 9 (depends on 8) The video data processing device according to claim 8, wherein the control unit acquires the video format information of each of the first video data and the second video data from a detection unit that detects the video format of each of the first video data and the second video data. ### Claim 10 (depends on 8) The video data processing device according to claim 8, wherein the video data input unit has a cross-point unit that selectively extracts the first video data and the second video data from a plurality of video data, and the control unit acquires the video format information of each of the first video data and the second video data from a table that has video format information of each of the plurality of video data. ### Claim 11 A video data processing method of obtaining output video data by performing mix processing on first video data and second video data, the video data processing method comprising the steps of: before performing the mix processing, making a format of the first video data and the second video data the same as a video format handled by the mixing processing, and after performing the mix processing, making a format of the output video data the same as an output video format. ### Claim 12 A video data processing device comprising: a video data input unit that inputs first video data and second video data; a mixing unit that mixes the first video data and the second video data inputted by the video data input unit and obtains output video data; and a video format conversion unit that is arranged between the video data input unit and the mixing unit and that makes a video format of the first video data and the second video data inputted into the mixing unit the same as a video format handled by the mixing unit.
