Based on the system, the embodiment of the invention provides a multi-signal window synchronous windowing display method and device, which are used for solving the technical problem that the conventional wall splicing processing technology cannot realize the synchronous windowing display of multi-signal windows.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a multi-signal window synchronous windowing display method according to an embodiment of the present invention.
The invention provides a multi-signal window synchronous windowing display method, which comprises the following steps:
step 202, determining at least one window group based on window information; wherein each window group comprises at least one window;
in the embodiment of the invention, batch windowing operation can be performed through preset wall-splicing control software, specifically, a windowing instruction is issued to a scheduling module of a processor, wherein the windowing instruction comprises signal source information and window information. The scheduling module may divide all windows into at least one window group based on the signal source information and the window information carried in the windowing instruction.
It should be noted that the wall splicing control software provided by the present invention can support the following several application scenarios of batch windowing:
supporting a multi-window scene formed by a plurality of single signals;
the method supports a high-resolution visual application scene formed by splicing a plurality of cascade signals;
and a multi-window application scene formed by a plurality of single signals and a plurality of cascading signals is supported.
According to different selected application scenes, the window division modes of the scheduling module based on the windowing instructions are different.
Specifically, the scheduling module may group the windows according to the signal source parameter information in the windowing instruction by using the following classification rule.
1. A single signal window belongs to a group, i.e. the group contains only one single signal window.
2. The multiple cascaded signal windows belonging to the same signal window matrix belong to the same group, namely the group comprises multiple windows, and the signal sources corresponding to each window can be spliced into a complete signal matrix.
In one example, when the wall-splicing operation software selects a multi-window scene composed of a plurality of single signals, the scheduling module responds to the windowing instruction, and can divide all window groups by taking each window as one window group.
Further, the scheduling module can calculate the windowing area of the small window of the node to be crossed according to the total windowing area of each window and the single-screen resolution of the display end, and the windowing area is described by adopting a coordinate relative to the single-screen resolution; in addition, the cutting area of the signal source corresponding to each small window can be calculated according to the windowing area of each small window and the resolution of the signal source, and the cutting area is described by adopting coordinates relative to the resolution of the signal source.
in the embodiment of the invention, the scheduling module can facilitate each window group and sequentially acquire the signal source information, then calculate the streaming media module with the minimum load in a load balancing mode according to the signal source connection number on each streaming media processing module, and send a signal source connection instruction to the streaming media module.
in the embodiment of the present invention, in order to ensure synchronous windowing display of multiple signal windows, it is necessary to ensure that timestamps of signal sources in each window group are the same. I.e. the time stamps of the signal sources are converted into the same time stamp of the signal source.
As shown in fig. 3, in a specific embodiment, the step of determining the time stamp of the signal source of each window in each window group may include:
s301, respectively obtaining the number of windows in each window group;
s302, when the number is more than 1, issuing a synchronization request to each streaming media processing module in the window group to obtain a signal source timestamp; wherein, the synchronization request carries synchronization parameters;
and S303, when the number of the signal sources is 1, converting the time stamp of the signal source through the streaming media processing module to obtain the time stamp of the signal source.
Specifically, when the scheduling module acquires the synchronization parameter of a signal source in a certain window group, if no synchronization parameter exists in the group, the synchronization parameter is used as the synchronization parameter of the group; otherwise, no processing is performed. Secondly, it can be determined that a single independent signal window or multiple cascaded signal windows are opened according to the number of signal sources in each group, and the streaming media processing module needs to be informed to adopt different strategies to convert the timestamps of the signal sources corresponding to the 2 different windowing scenes. The specific rule is as follows:
when a single independent signal is windowed: that is, when the number of windows is 1, the signal source synchronization parameter in the window group can be ignored, and the scheduling module notifies the streaming media processing module to still adopt the current method to convert the signal source timestamp.
Multiple cascaded signal windowing: that is, when the number of windows in a window group is greater than 1, a scheduling module can obtain the synchronization parameter in the window group, and then send the synchronization parameter to the streaming media processing module corresponding to each signal source in the window group, and all the streaming media processing modules are required to convert the time stamp of the signal source according to the synchronization parameter, thereby ensuring that all cascaded signal sources in the group can synchronously convert the time stamp.
and step 206, synchronously sending window display information to a preset display terminal based on the time stamp of the signal source.
In an embodiment of the present invention, the window display information may include first display information, second display information, and third display information. In one example, the first display information may be signal source real-time display information; the second display information may be "signal source being connected" information, and the third display information may be "signal source abnormality" information.
In the embodiment of the present invention, as shown in fig. 4, the process of determining the window display information may include the following steps:
s401, acquiring a windowing time length;
s402, judging whether the windowing time length reaches a preset windowing overtime threshold value;
s403, if yes, judging whether decoding information returned by each decoding display module based on the windowing parameters is received;
s404, if yes, the first display information is used as window display information; the first display information is real-time display information of the signal source;
and S405, if not, using the second display information as window display information.
S406, acquiring a signal source connection state;
s407, when the signal source connection state is not the connection timeout state, using the first display information as window display information.
S408, when the signal source connection state is a connection overtime state, judging whether decoding information returned by each decoding display module based on the windowing parameter is received;
and S409, if so, using the first display information as window display information.
And S410, if decoding information returned by each decoding display module based on the windowing parameters is received, taking the third display information as window display information.
In a specific implementation, when the scheduling module detects that the windowing duration reaches the preset windowing timeout threshold, it may be determined whether each decoding display module has reported decoding information of "decoding completion", if so, the window display information may be real-time display information of the signal source, and if there is a decoding display module that has not reported decoding information of "decoding completion", the window display information may be "signal source is being connected".
When the scheduling module detects that the connection state of the signal source is connection, the window display information can be real-time display information of the signal source.
When the scheduling module detects that the connection state of the signal source is a connection overtime state, namely the connection state of the signal source and the streaming media processing module is overtime and not connected, judging whether each decoding display module reports decoding information of decoding completion again; if the information is not reported, the window display information is 'signal source abnormity' information; otherwise, no processing is carried out, namely the window display information is the signal source real-time display information.
After the scheduling module detects that the connection state of the signal source is the connection overtime state, when decoding completion decoding information reported by all the decoding display modules is received, window display information can be switched to signal source real-time display information.
For easy understanding, please refer to fig. 5, wherein fig. 5 is a flowchart illustrating a multi-signal window synchronous windowing display method according to an embodiment of the present invention. The specific process comprises the following steps:
1. and the control end issues a windowing instruction through the wall splicing control software so as to perform batch windowing.
2. And after receiving the windowing instruction, the scheduling module groups the windows, issues windowing parameters to the corresponding decoding display module, and sets the window display attribute to be in a hidden state in the parameters.
3. Judging whether the number of signal sources in the window group is greater than 1, if not, ignoring the synchronization parameter, and converting the signal source timestamp through the streaming media processing module; if yes, setting a synchronization parameter, and converting the signal source timestamp based on the synchronization parameter through the streaming media processing module.
4. Judging whether the windowing time length reaches a preset windowing overtime threshold value or not, and if not, not processing the display information of the display end; if so, judging whether the decoding display module reports decoding information, and displaying the signal source real-time display information on the display end when the decoding display module reports the decoding information; and when the decoding display module does not report all the decoding information, displaying the information of 'connecting the signal source' on the display end.
5. Judging the connection state of the signal source, and when the connection state of the signal source is not the connection overtime state, not processing the display information of the display end; when the connection state of the signal source is a connection overtime state, judging whether the decoding display module reports decoding information again; when the decoding display module reports the decoding information, the signal source real-time display information is displayed on the display end; and when the decoding display module does not report all the decoding information, displaying the information of 'connecting the signal source' on the display end.
