In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a high-definition video playing method provided in an embodiment of the present application, where the high-definition video playing method provided in the embodiment of the present application may be executed by a high-definition video playing apparatus, and the high-definition video playing apparatus may be implemented by hardware and/or software and integrated in a computer device.
The following description will be given by taking an example of a high definition video playback apparatus executing a high definition video playback method. Referring to fig. 1, the high definition video playing method includes:
s101: the screen selection area is determined in response to a display area selection operation.
The display area selection operation is used for selecting a local picture to be played in the video information, and the display area selection operation can be performed in the process of selecting to play the video information or playing the video information. Optionally, the partial picture is a picture corresponding to a rectangular region in the complete picture.
In this embodiment, after the played video information is determined, the video information is decoded to obtain a complete picture with the original resolution and played, and a local picture in the complete picture is displayed on a playing interface (the resolution corresponding to the local picture is consistent with the resolution of the playing interface), at this time, the played whole complete picture is the video information, but the local picture is the video information in the display interface. Alternatively, the default position of the partial picture may be the middle or upper left corner position of the full picture.
In one embodiment, when video information is selected to be played and only part of pictures in a playing interface are desired to be displayed, after the video information needing to be played is determined, a request for selecting a display area is initiated, a selection position (a center position or an angular point position) corresponding to the picture selection area is specified, the size of the interface of the playing interface is determined as the selection size of the picture selection area, and the picture selection area can be determined according to the selection position and the selection size.
In one embodiment, in the process of playing the video information (at this time, the complete picture of the video information is adjusted in an equal proportion to be suitable for the playing interface), when the playing interface is expected to display only part of the pictures, a request for selecting the display area can be initiated in the playing interface, the selection position corresponding to the picture selection area is specified, the size of the interface of the playing interface is determined as the selection size of the picture selection area, and the picture selection area can be determined according to the selection position and the selection size.

S102: and determining a local picture corresponding to the picture selection area in the complete picture of the video information according to the mapping relation between the picture selection area and the complete picture of the video information.
The mapping relation between the picture selection area and the complete picture of the video information is used for recording the corresponding relation between the coordinate points on the picture selection area and the coordinate points on the video information. For example, when the video information is decoded at the original resolution, the coordinate points on the picture selection area and the coordinate points on the video information are in a one-to-one correspondence relationship, that is, the coordinate points on the picture selection area and the coordinate points on the video information are consistent.
Illustratively, after determining the picture selection area, according to the mapping relationship between the picture selection area and the complete picture of the video information, the partial picture corresponding to the picture selection area is determined in the complete picture of the video information.
For example, the coordinates of the selection position of the picture selection area are determined, and the corresponding coordinates in the complete picture are determined according to the mapping relation between the picture selection area and the complete picture, the coordinates are the local position of the local picture, and meanwhile, the selection size of the picture selection area is used as the local size of the local picture, so that the range of the local picture in the complete picture of the video information is determined according to the local position and the local size.
S103: and displaying the local picture in a playing interface based on the playing process of the video information.
Illustratively, after determining the partial picture in the complete picture of the video information, the video information is continuously decoded and played, and the partial picture is played in the playing interface, at this time, only the partial picture in the complete picture is displayed in the whole playing interface. The playing interface provided by this embodiment may be displayed in the form of a window in the display screen or displayed in full screen, for example, the whole display screen of the television is used as the playing interface.
The embodiment decodes the whole complete picture of the video information, does not need to intercept the interested part in the complete picture in advance, determines the interested partial picture in the complete picture in real time, and only displays the partial picture in the playing interface in the process of playing the complete picture, wherein the playing interface is equivalent to a playing window which can slide in the complete picture.

Fig. 2 is a flowchart of another high-definition video playing method according to an embodiment of the present application, where the high-definition video playing method is an embodiment of the high-definition video playing method. Referring to fig. 2, the high definition video playing method includes:
s201: and acquiring and playing a complete picture of the video information, and displaying a partial picture in the complete picture in a playing interface.
The video information provided by this embodiment may be a video file or a high definition video or an ultra high definition video corresponding to a streaming media (e.g., a streaming media in a live application field), such as a high definition video of 4K, 8K, 16K, or more.
The method comprises the steps of firstly decoding video information to obtain a complete picture with the original resolution, playing the complete picture according to the original resolution, and displaying a local picture in the complete picture on a playing interface. The resolution corresponding to the local screen is consistent with the resolution of the playing interface, for example, the resolution corresponding to the playing interface is 1920x1080, and the resolution corresponding to the local screen is 1920x 1080.
At the moment, the whole complete picture of the video information is played, but the local picture is displayed in the display interface, and because the complete picture is a high-definition picture, when the size of the display screen (playing interface) is smaller and is not enough to embody the playing advantage of high-definition image quality, the local picture is played in a full screen mode, and the playing picture is still high-definition.
S202: a selection position of the screen selection area is determined in response to a display area selection operation.
Specifically, when a partial interested area in the complete picture needs to be selected, the area selection trigger button or the action triggers the display area selection operation, and the selected position is clicked in the playing interface or selected in a coordinate input/selection mode.
Optionally, in the process of selecting the selection position, the position of the selection position in the complete picture can be displayed in the play interface, so that the selection operation of the selection position is facilitated.
S203: and determining the selection size of the selection area according to the interface size of the playing interface.
Specifically, the selection size of the selection area is set to be consistent with the interface size of the play interface in the present embodiment. Further, the interface size and the selected size in this embodiment are specifically resolution, for example, if the resolution corresponding to the interface size is 1920x1080, the selected size is 1920x 1080. Generally, the resolution of the complete picture is greater than the resolution of the playing interface.
S204: and determining the mapping relation between the picture selection area and the complete picture of the video information according to the set local picture scaling.
Specifically, after the display area selection operation is detected and the picture selection area is determined, the mapping relationship between the picture selection area and the complete picture of the video information is determined according to the set local picture scaling. The local picture scaling can be set by mouse wheel rolling, proportional slider sliding, percentage input and the like, and the default local picture scaling is 1: 1.
in one possible embodiment, a setting operation of the local screen scaling is detected in real time during the displaying of the local screen, and the local screen scaling is updated in real time in response to the setting operation.
For example, assume that the set local screen scaling is 1: 1, namely the distance of the partial picture is consistent with the distance standard of the complete picture, the mapping relationship is as follows: the coordinates in the picture selection area and the coordinates in the complete picture of the video information are 1: 1; assume that the set local screen scaling is 2: 1, namely, the distance of the partial picture is twice as long as the distance of the complete picture, the mapping relationship is: the coordinates in the picture selection area and the coordinates in the complete picture of the video information are 1: 2, for example, the coordinates in the picture selection area are (3, 6), the corresponding coordinates in the complete picture of the video information are (6, 12).
S205: and determining a local picture corresponding to the selection position and the selection size in the complete picture of the video information according to the mapping relation between the picture selection area and the complete picture of the video information.
Specifically, after the mapping relationship between the picture selection area and the complete picture of the video information is determined, the corner coordinates of the four corners of the picture selection area are determined according to the selection position and the selection size corresponding to the picture selection area.
Furthermore, according to the mapping relationship between the picture selection area and the complete picture of the video information, four coordinate points corresponding to the corner point coordinates of the four corner points of the picture selection area in the complete picture are determined, and the picture of the complete picture of the video information corresponding to the area surrounded by the four coordinate points is the local picture which needs to be displayed in the playing interface.
For example, assume that the default local picture scaling is 1: 1, determining that the coordinates of the corner points of the four corner points of the picture selection area are respectively A1(128 ), B1(128, 256), C1(256, 128) and D1(256 ) according to the selection position and the selection size corresponding to the picture selection area, wherein the picture surrounded by the corresponding coordinates A2(128 ), B2(128, 256), C2(256, 128) and D2(256 ) in the complete picture of the video information is a local picture.
Assume that the default local picture scaling is 2: 1, determining that the coordinates of the corner points of the four corner points of the picture selection area are respectively A1(128 ), B1(128, 256), C1(256, 128) and D1(256 ) according to the selection position and the selection size corresponding to the picture selection area, wherein the picture surrounded by the corresponding coordinate points A2(256 ), B2(256, 512), C2(512, 256) and D2(512 ) in the complete picture of the video information is a local picture.
S206: and continuously playing the video information to obtain a complete picture of the video information.
Specifically, after determining a partial picture in the complete picture, the video information is continuously decoded and played to obtain a complete picture corresponding to the video information.
S207: and displaying the partial picture in the complete picture of the video information in a playing interface.
Specifically, the partial screen determined in step S205 is displayed in the playback interface. It can be understood that, in the process of displaying the partial picture, the part of the complete picture outside the partial picture is not shown in the playing interface.
It should be explained that, in the present embodiment, when playing the video information, the whole full picture is played, but only the partial picture is displayed in the playing interface, and the size of the partial picture is consistent with the interface size of the playing interface, and the picture size of the full picture is larger than the interface size.
Fig. 3 is a schematic diagram of a display effect of a complete picture in the prior art, as shown in fig. 3, in the prior art, a solid line frame S2 in the figure is a display screen, a display area of the whole display screen is a play interface, a picture displayed in the play interface is a complete picture, after decoding video information to obtain the complete picture, the whole complete picture is displayed in the play interface, the picture displayed in the complete picture in the figure is "good weather today", and is limited by the size of the display screen, and the advantage of high definition picture playing (picture quality of 4K, 8K, 16K and above) cannot be embodied.
Fig. 4 is a schematic view of a partial picture showing effect provided in an embodiment of the present application, as shown in fig. 4, a range corresponding to a dashed-line frame S1 in the drawing is a complete picture of video information, a solid-line frame S2 is a display screen, a display area of the entire display screen is a play interface, a picture shown in the play interface is the partial picture, a picture displayed in the complete picture in the picture is "weather today is really good", and a picture displayed in the partial picture is a portion corresponding to "weather" in the partial picture, at this time, the picture of "weather" can be observed more clearly.
S208: the screen selection area is updated in response to the display area moving operation.
Specifically, the display area moving operation is detected in real time, when the display area moving operation is detected, the selection position corresponding to the picture selection area is redetermined in real time, and the position of the partial picture on the complete picture is redetermined according to the updated selection position. The real-time updating of the local frame can refer to steps S204-S206, and the description of this embodiment is omitted.
The display area moving operation can be performed in modes of screen clicking and dragging, direction key clicking, gesture sliding, coordinate input, body sensing induction, voice instructions, image recognition instructions, mouse control (including a wired mouse, a wireless mouse and a gyroscope air mouse), a remote controller, customized control equipment and the like. Specifically, when the display area is displayed by touching the display screen, directional movement buttons, such as four directional buttons of "up", "down", "left" and "right", are displayed in the display area, and a user can click a directional key to control the movement switching of the partial screen; in another example, also taking a touch screen as an example, the user may switch the display content of the partial screen by performing a screen-click drag on the touch screen; in another example, the user may perform switching of the display content of the partial screen through a remote controller, for example, a direction button is provided in the remote controller, and the user clicks the corresponding direction button to perform movement switching of the partial screen in the corresponding direction; in another example, the gesture of the user can be detected in a somatosensory sensing manner, and if the gesture that the hand of the user swings from left to right is detected, the local picture is correspondingly controlled to be switched in a rightward translation manner; in another example, the local screen may be switched and moved accordingly by detecting a voice command, such as recognizing the collected voice of the user, when a keyword including "up, down, left, right" and the like is recognized. It should be noted that the manner of switching the playback in this scheme is not limited to the above example, and any scenario applicable to the playback mode in this scheme may fall within the scope of the application.
For example, in the live broadcast field, when astronomical phenomena such as eclipse and the like or high-definition video (8K video) of natural and scenic scenes are directly broadcast, due to the display of the size of the display, if the video information with the resolution of 8K is completely displayed, details of an attention target (for example, a local area corresponding to the sun) are difficult to display on the display, at this time, a display area selection operation can be initiated according to the position of the attention target, a picture selection area is selected, a local picture corresponding to the attention target in the complete picture of the video information can be further determined according to the picture selection area, and the local picture is displayed in the whole playing interface of the display, so that the picture details of the attention target can be conveniently observed.
