Description

CROSS REFERENCE TO RELATED APPLICATIONS The present disclosure is a continuation application of International Application No. PCT/EP2022/069163 filed Jul. 8, 2022, which claims the benefit of priorities to Chinese Patent Application No. 202110778853.8, filed on Jul. 9, 2021, Chinese Patent Application No. 202110796909.2, filed on Jul. 14, 2021, Chinese Patent Application No. 202110961753.9, filed on Aug. 20, 2021, and Chinese Patent Application No. 202111051666.6, filed on Sep. 8, 2021, which are incorporated in the present disclosure in their entireties by reference. FIELD The present disclosure relates to display technology, and in particular to a refreshing method and a display apparatus. BACKGROUND A display apparatus supports Dolby Vision IQ in some scenarios. Dolby Vision IQ supports a High-Dynamic Range (HDR) picture adjustment function of original Dolby Vision, an adaptive picture quality adjustment function based on ambient brightness, etc., thus the display apparatus provides users with better viewing experience, with optimal picture quality in different scenes. Dolby Vision IQ further supports an Automatic Playback Oppimivation (APO) function. With this function, when watching a video, a user can synchronously view a picture mode settings menu where parameters of picture quality setting options matching a current video are displayed. Each source video has a corresponding content type, for example, movie, game, sports etc. for indicating video theme or content characteristics. Videos with different content types have different picture quality parameters. Therefore, in a case that the content types of the videos are switched, related parameter settings in a picture mode settings menu should be updated accordingly. In the case where one source video has multiple content types, for example, when a clip A of a movie presents a game picture, that is, game contents are integrated into the movie, a user might view picture quality parameters of a previous content type after invoking a menu in a continuous playing process of such a special video, and real-time synchronization between a menu and a video content is still unavailable. In this case, the user needs to pause playing the video, and manually refresh the menu, for example, return to a previous menu first and then enter a next picture mode settings menu, so as to update parameters of picture quality settings in the picture mode settings menu, resulting in poor real-time synchronization between a menu and a video content, complicated operations and poor viewing experience. SUMMARY The present disclosure provides a display apparatus. The display apparatus includes a display configured to present a video, where the video is configured with a picture mode settings menu, and the picture mode settings menu includes at least one picture quality setting option and one of the at least one picture quality setting option includes a parameter; and a controller in connection with the display and configured to: present a video on the display, wherein the video has one or more content types, and the video comprises a first section with a first content type and a second section with a second content type; detect whether a content type of the video is switched from the first content type to the second content type; obtain first picture quality parameter information matching the second content type from preset data of the display apparatus, where the preset data includes a predefined relation between a content type and picture quality parameter information, and the first picture quality parameter information includes a parameter of at least one picture quality setting option corresponding to the second content type; and control the display to update the parameter of the at least one picture quality setting option in the picture mode settings menu according to the first picture quality parameter information and to present the second section of the video according to the updated parameter of the at least one picture quality setting option in the picture mode settings menu. The present disclosure further provides a refreshing method for a display apparatus. The method includes: presenting a video on a display of the display apparatus, wherein the video has one or more content types, and the video includes a first section with a first content type and a second section with a second content type; detecting whether a content type of the video is switched from the first content type to the second content type; obtaining first picture quality parameter information matching the second content type from preset data of the display apparatus, the preset data including a predefined relation between a content type and picture quality parameter information, the first picture quality parameter information including a parameter of at least one picture quality setting option in a picture mode settings menu of the video corresponding to the second content type, and one of the at least
