With the change of video wall upgrade in time TV screen broadcasting control, advantageously ensure that video wall work flexibility.
Brief description of the drawings
Fig. 1 is a kind of instant switching method flow chart of broadcasting pictures for video wall proposed by the present invention.
Embodiment
Reference picture 1, the instant switching method of a kind of broadcasting pictures for video wall proposed by the present invention, including.
S1, preset plane coordinate.
S2, TV screen distribution map drawn in plane coordinates according to the relative position of each TV screen.
S3, display screen assembled state is determined according to TV screen distribution map, display screen is a complete view screen, and it can
To be that multiple TV screens combine or an independent TV screen.
Specifically, display screen assembled state includes：The TV screen and its ranking that display screen quantity, each display screen include.This
In step, it is determined that during display screen assembled state, whether the distance by judging adjacent TV screen is equal to 0 or enters less than 0
Row judges.In the case of 0, identify two adjacent TV screens and be brought into close contact；In the case of 0, adjacent two are represented
Individual TV screen is connected by the way of being mutually embedded in.In practical application, each TV screen on video wall typically uses parallel sliding
Motion mode, so, the distance of adjacent TV screen can be by calculating the close to each other of two TV screens in plane coordinates
And the distance of two parallel seamed edges is assessed.
S4, according to display screen assembled state, treat played file and handled, obtain the instant played file of each TV screen
And play out.In this step, the corresponding relation of file to be played and each display screen is first confirmd that.It is if for example, to be played
File only has one, then multiple display screens play out to same video to be played.Because the TV screen of each display screen combines
Situation is different, so, Video Quality Metric file, which needs to treat played file first, to be handled, and obtains the association of each display screen
Played file, segmentation is then carried out to association played file according to the TV screen combined situation of display screen and obtains each TV screen
Played file.
If file to be played has multiple, the corresponding relation of each display screen and each file to be played is determined first, and drive
File to be played corresponding to dynamic each display screen broadcasting.Because the TV screen combined situation of each display screen is different, so, Video Quality Metric
File, which needs to treat played file first, to be handled, and the association played file of each display screen is obtained, then according to display
The TV screen combined situation of screen carries out the played file that segmentation obtains each TV screen to association played file.
The positioning of each TV screen on S5, real-time monitoring television wall.
S6, determine whether that TV screen position changes.It is no, then return to step S5.
S7, it is then to update TV screen distribution map in plane coordinates, be then back to step S3.
,, will be each by the way that each TV screen on video wall is mapped in plane coordinates with reference to plane coordinates in present embodiment
The position instantiated of TV screen, so as to which the combined situation of the TV screen position judgment TV screen according to instantiated is display screen combination
State.In this way, by coordinate value, the mutual distance of TV screen is converted into tool as value by arbitrary value, advantageously ensured that aobvious
The accuracy of the judgement of display screen assembled state, it is to control the video playback of each TV screen to establish base according to display screen assembled state
Plinth.
In present embodiment, by the positioning of each TV screen on the real-time monitoring television walls of step S5, and when on video wall
When display screen assembled state changes, then the video playback of each TV screen is controlled according to new TV screen distribution map.It is in this way, real
Showed with the change of video wall upgrade in time TV screen broadcasting control, advantageously ensure that video wall work flexibility.
Embodiment 1
In the present embodiment, step S5 specifically includes following steps.
S51, the object of reference that fixed position is set, the coordinate points of object of reference are set in screen coordinates.
S52, the set location sensor on each TV screen, detected by position sensor between TV screen and object of reference
Vector value.
S53, the vector value of monitoring each position sensor detection in real time.
In the present embodiment, because locator is relative with the TV screen at place stable, each locator with reference to same object of reference, therefore
And, it is ensured that the vector value detected by position sensor is consistent with the actual distribution situation of each TV screen on video wall.
In the step S6 of the present embodiment, judge whether TV screen position position changes by vector value.In this way, will prison
The monitoring for surveying the relative position of each TV screen is converted to the monitoring of the vector value to position sensor detection, advantageously reduces monitoring
Difficulty, improve monitoring accuracy and operating efficiency.
In the present embodiment, step S2, can by the detected value of each position sensor by each TV screen using object of reference as reference
Coordinate is mapped to acquisition plane coordinates distribution map in screen coordinates.
In the present embodiment, in step S7, the concrete mode for updating TV screen distribution map in plane coordinates is：According to each TV
Each TV screen is mapped to by the relative position relation of screen and object of reference obtains new TV screen distribution map in plane coordinates.
Embodiment 2
In the present embodiment, in step S2, the phase of each TV screen of graphical analysis acquisition is carried out by the shooting image of video wall
To position.That is, filming apparatus is installed in the present embodiment captured in real-time is carried out to video wall.In this way, in step S5 steps, by right
Video wall carries out captured in real-time, and shooting image is analyzed, and obtains the positioning of each TV screen on video wall.
When it is implemented, in step S2 of the present invention, TV screen distribution map can also hand drawn.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
