In the case of unsuccessful, the operating result can be merely sent to send the client of control data；Can also be sent to all
Client so that all clients are all known and currently send the operational motion that the client of control data is performed to video wall.
In the present embodiment and following each embodiment, multiple client is due to will synchronously show the state of video wall
(i.e. the logic placement of video wall and broadcasting video state), and user-friendly video wall is, it is necessary to every in video wall
Individual display is numbered, and the identity of each video wall display is represented to number.Numbering can have many according to actual situation
Arranged mode is planted, the mounting means of display can be regular installation, or irregular installation in video wall.It is such as following
Described in embodiment：There is provided a kind of display with 4*4, and the video wall numbering that display is carried out into rule installation is (i.e.
The array arrangement of display on video wall into 4*4)：
According to from top to bottom, order from left to right is by display serial number：The volume of the first row display of the top
Number 0,1,2,3 are respectively, the numbering of second row display is：4th, 5,6,7, the numbering of the 3rd row's display is respectively：8、9、10、
11, the numbering of the 4th row's display is：12、13、14、15.
The numbering that the first row of the top shows is respectively：1-1、1-2、1-3、1-4；The numbering of second row display is：
2-1,2-2,2-3,2-4, the numbering of the 3rd row's display are respectively：3-1,3-2,3-3,3-4, the numbering point of the 4th row's display
It is not：4-1、4-2、4-3、4-4.
The numbering that the first row of the top shows is respectively：a-1、a-2、a-3、a-4；The numbering of second row display is：
B-1, b-2, b-3, b-4, the numbering of the 3rd row's display are respectively：C-1, c-2, c-3, c-4, the numbering point of the 4th row's display
It is not：d-1、d-2、d-3、d-4.
It should be noted that being only above there is provided several methods that specific numbering is carried out to display.And according to reality
The need for border, the numbering of display can also be set to other by the quantity of such as display, comfort level of identiflication number etc.
Form.
If the display on video wall is irregular installation, for example, the rule of display is not supported due to the space installed
Installation, or display is diversified in specifications, and size is different, it is also possible to reference to above-mentioned method for numbering serial, display is compiled successively
Number.
In video wall, the location expression of each display is represented using rectangular coordinates { x, y, width, height },
With video wall upper left angle point as origin (0,0), x-axis forward direction is extended to the right, it is positive y-axis to extend downwardly, it is assumed that by a base
The height and width of quasi- display regard 1 as respectively, then in above-mentioned rectangular coordinates, and x represents that display is positive in x-axis, most
Close to the coordinate of origin, and y represents that display is positive in y-axis, closest to the coordinate of origin.Width represents the display of video wall
Device length (length extended i.e. in x-axis) in the direction of the width, height represents the display of video wall in short transverse
On length (length for extending on the y axis).
It is that a kind of display is arranged video wall in the form of an array for example, with reference to Fig. 7 a and Fig. 7 b, Fig. 7 a, Fig. 7 b are a kind of aobvious
Show the video wall that device is irregularly arranged.Numbering to display is specifically shown in shown in figure：
For example, display 7 is represented with { 2,1,1,1 } in 7a, display 6 is represented with { 1,1,3,3 } in such as Fig. 7 b.
Description to the physical layout of whole video wall uses the rectangular coordinates of video wall numbering and display present position
Common description, for example, the description of the physical layout of video wall shown by Fig. 7 b can be expressed as：
[{“index”:0,“rect”:{0,0,1,1}},{“index”:1,“rect”:{1,0,1,1}},{“index”:
2,“rect”:{2,0,1,1}},{“index”:3,“rect”:{3,0,1,1}},{“index”:4,“rect”:{4,0,1,
1}},{“index”:5,“rect”:{0,1,1,1}},{“index”:6,“rect”:{1,1,3,3}}]。
Again because the logic placement of video wall is the physical layout based on video wall, it is therefore possible to use logic region
Gather and the placement scheme of the logic placement of video wall is described.And each logic region potentially includes a display
(also known as independent screen), potentially includes multiple displays (also known as mosaic screen).Wherein, when logic region is for independent screen, logic area
Numbered by the display in corresponding physical layout and represented in domain；When logic region is mosaic screen, logic region is by corresponding physics
The set expression of the display numbering in layout.6,7,11,12 four displays have been combined into a mosaic screen in video wall, other
Logic region be all independent screen, then now the placement scheme of the logic placement of video wall can be expressed as:
[{“type”:“clip”,“index”:0},{“type”:“clip”,“index”:1},{“type”:“clip”,
“index”:2 } ..., { " type ":“clip”,“index”:5},{“type”:“splice”,“index”:[6,7,11,12]},
{“type”:“clip”,“index”:8},…,{“type”:“clip”,“index”:24}]
In several of the above embodiments where, when control data includes current arrangements' control instruction, current arrangements' control refers to
The video wall layout information carried in order, the video wall layout information can include：User wants to patrol the current of video wall
After volume layout is changed, the placement scheme of the new logic placement for being formed；Can also include：User is wanted video wall
After current logic layout is changed, the placement scheme corresponding to logic region that generation more changes.
It is shown in Figure 3, in the video wall management method of the multi-client synchronization that the embodiment of the present invention is provided, the control
System request includes prediction scheme control instruction；Pre- pattern identification is carried in the prediction scheme control instruction.
The television wall server is operated accordingly according to the control data for receiving, and generates operation knot

S301：The television wall server carries out increase prediction scheme according to the prediction scheme control instruction, or to existing prediction scheme
The operation deleted or changed；
S302：The television wall server generates operation result information according to the result of operation.
When implementing, prediction scheme is specifically played by the placement scheme of logic placement and based on the placement scheme
Video information collectively form.Therefore, to the control of prediction scheme, can be directed to placement scheme in prediction scheme control, or
For the control of the video information to be played, or simultaneously for both control.Wherein video information includes：Audio-video source
UUID (Universally Unique Identifier, general unique identifier), the logic area for playing the audio frequency and video
The information such as identification marking, the title in domain.
When implementing, actually prediction scheme control instruction has following different several situations：
1st, the prediction scheme control instruction is used for the operation for indicating to increase certain prediction scheme.Prediction scheme is carried in prediction scheme control instruction
Placement scheme, and carry video information corresponding to placement scheme.Television wall server receive the prediction scheme control refer to
After order, can by comprising placement scheme therefrom parse, according to the placement scheme, create new prediction scheme, and in prediction scheme extremely
A few logic region associates corresponding video information.Corresponding operation result information is generated, in the operation result information, bag
The placement scheme and video information of new prediction scheme are included.It is further noted that in the operation result information, can also wrap
Include：The time that prediction scheme is created, the information such as the user of establishment, can also include the title of the prediction scheme that user be input into client or
The information such as person's label.
In addition, in order to avoid the repetition of the new prediction scheme and original prediction scheme for creating is created, before prediction scheme establishment is carried out, TV
Wall server can also according to the placement scheme of prediction scheme, and its other prediction scheme for being stored placement scheme, judge that user thinks
Whether the new prediction scheme to be created has been present, if it is present creating failure, and is sent out to the client for sending prediction scheme control instruction
Send the operation result information for creating and failing.In the operation result information, the reason for creating failure can be included, created pre-
The information such as title, label, identification marking, establishment user, the creation time of case.The prompting of establishment failure, can be only sent to
Send the client of prediction scheme control instruction, it is also possible to all of client send so that all of client can know work as
The specific action of the preceding client for sending prediction scheme control instruction.
2nd, the prediction scheme control instruction is used for the operation for indicating to modify certain prediction scheme.Carried in prediction scheme control instruction
There is new placement scheme, or carry the placement scheme corresponding to the logic region for producing change.If to be broadcast to prediction scheme
