With the development of the multi-channel video playing technology, the number of video sources integrated into the front end display is increasing, however, the number of video channels that can be displayed by the front end is limited and is far less than the number of video sources that can be displayed.
In the existing multi-video playing mode, each channel can only play a fixed video source, which results in limited number of supported channels, low utilization rate of system resources, and poor expandability.

Illustratively, the playing method, the playing device and the processing device for implementing the multi-channel video according to the embodiments of the present invention may be implemented as an intelligent terminal, such as a smart phone, a tablet computer, a display screen, and the like.
Example two:
in accordance with an embodiment of the present invention, there is provided a method for playing multiple videos, it should be noted that the steps shown in the flowchart of the figure may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown.
Fig. 2 is a flowchart of a playing method for multiple channels of video according to an embodiment of the present invention, and as shown in fig. 2, the method is applied to a scene displayed by a front end shared by multiple channels of video, and includes the following steps:
step S202, at least one target attribute is respectively determined for each path in the multi-path video.
When there are multiple channels of videos to be displayed and the total channel number of the multiple channels of videos is greater than the channel number of the videos that can be simultaneously played at the front end, the method can be executed according to the playing method of the multiple channels of videos provided by the embodiment, and a part of the videos are selected to be played. When the multi-channel video exists, at least one target attribute may be determined for each channel, and the target attribute may also be referred to as an algorithm index for subsequent priority determination.
If only one attribute is acquired by a certain path of video, the attribute is taken as a target attribute, and if a plurality of attributes of the video are acquired, all the attributes can be taken as the target attribute, or part of the attributes can be selected as the target attribute. In the process of selecting the target attribute, the target attribute may be determined according to the characteristics of the monitored object of the current multi-channel video, or according to the interested or concerned aspect of the user, or according to the important concerned aspect of the video playing system. It should be noted that, which of the attributes are changeable as target attributes, that is, the target attributes may be changed according to the requirements of the user or the system, that is, the target attributes may be dynamically selected, so as to focus on different aspects of the multi-channel video, and the display is flexible and the user experience is high.
And step S204, acquiring target attribute information of each path of video according to the target attribute.
After the target attributes are obtained, target attribute information corresponding to each target attribute needs to be further obtained, where the target attribute information may be a specific value corresponding to the target attribute, for example, the target attribute is the number of objects in the video, and the target attribute information may be a numerical value of the number of the objects. The target attribute information may include: whether there are target objects, the number of target objects, motion information of the target objects, identity information of the target objects, or location attributes of the video source, which may include speed, dwell time, dwell law, etc.
The object attribute information may be determined based on a video recognition technology, or may be determined based on source information of the video itself, for example, the number of objects in the video, a distribution rule of the objects, a time length in which the objects exist, a moving speed of the objects, a staying rule of the objects, or identity information of the objects, which are determined based on the video recognition technology, or may be information based on an image capturing device corresponding to the video itself, such as a position of the image capturing device, an area to which the image capturing device belongs, or importance of the image capturing device.
When the target attribute information of a certain path of video is obtained, all the attribute information of the path of video can be obtained first, and the target attribute information is obtained from all the attribute information according to the target attribute, or the target attribute can be determined first, and then the target attribute information corresponding to the video is obtained directly according to the target attribute.
Step S206, calculating the target attribute information based on a preset priority algorithm to obtain the priority information of each path of video.
The preset priority algorithm may adopt an existing algorithm, such as a probability distribution algorithm, a multi-attribute priority decision algorithm, or a dynamic programming algorithm. For example, by adopting a probability distribution algorithm, the obtained target attribute information obeys the probability distribution, the approximate position of each data sequence is calculated through a density function of the probability distribution, and the sequence of the target attribute information can be obtained by slightly sorting; by adopting a multi-attribute priority decision algorithm, one-dimensional vectors corresponding to a plurality of attribute information can be integrated into a numerical value through the algorithm, and then the numerical value is compared to judge the priority, for example, the algorithm such as an ordered average weighting operator is adopted; and solving each attribute information as a subproblem by adopting a dynamic programming algorithm, listing various possible local solutions when any subproblem is solved, reserving the local solution which is possibly optimal through decision, and solving each subproblem in sequence, wherein the last subproblem is the optimal solution of the initial problem, so that the video with the highest priority is obtained.
And calculating the priority information of each path of video according to the target attribute information by using a priority algorithm, thereby obtaining a basic basis for selecting to play the video.
And S208, screening the multi-channel video according to the preset rule and the priority information to obtain the video to be played and playing the video to be played.
The preset rule may be a rule configured in advance by a user, or a rule input by the user in real time. The above rules may be defining the number of screened videos, defining the position of videos in the ranking, etc. After screening is carried out based on the rule, the video to be played is obtained, a corresponding video source does not need to be set for each channel of the front end in advance, and a proper number of videos to be played can be selected from more video sources, so that more video channels can be supported, and the expandability is good; through priority screening, the front-end playing content can be concentrated on meaningful videos, and the resource utilization rate of the system and the value of the system to users are improved. The video source corresponding to the video to be played is accessed, and the video received from the video source is played, for example, a video channel corresponding to the video to be played can be connected to a playing channel of the display device, so that the display device displays the video to be played.
According to the multi-channel video playing method provided by the embodiment of the invention, the target attribute information of the multi-channel video is obtained, the priority information is calculated according to the target attribute information, the video to be played is obtained by screening according to the preset rule and the priority information, then the video to be played is played, the most concerned video content can be displayed for the user, the system resource is saved, and the appropriate number of videos to be played are selected according to the priority, so that more video channels can be supported, and the video expansion is supported.
When multiple videos needing to be displayed exist, in order to select a high-value video from the videos to access the front end for display, attribute configuration may be performed on all the videos, and by selecting a suitable attribute as a target attribute and extracting attribute information of each target attribute, subsequent priority calculation may be performed specifically according to the following two ways:
(1) and receiving a configuration instruction input by a user, and determining a target attribute of each path of video from a plurality of attributes according to the configuration instruction. Considering that the user needs to change the target attribute, the configuration instruction input by the user can be received in real time, the configuration instruction comprises the target attribute of each path of video, and the target attribute of each path of video can be the same or different, which indicates the focus of the user's current attention.
(2) And determining the target attribute of each path of video according to the configuration rule corresponding to each path of video.
It should be noted here that different configuration rules or the same configuration rule may be preset for each video, and if the target attribute is determined by the different configuration rules, the video may be sorted after the subsequent priority calculation, without affecting the screening according to the sorting result. In the case where the arrangement rules are different, for example, the plurality of image capturing apparatuses may be divided into a plurality of different types, or the plurality of image capturing apparatuses may be divided into a plurality of different areas, and the emphasis of the user concerning the different types or areas is different, it is more effective to use the different arrangement rules.
When the multi-channel video is screened to obtain the video to be played, the video with the level higher than the preset level corresponding to the priority information can be determined as the video to be played, for example, the priority is three levels in total, and the video with the highest priority can be directly selected to be output; the multi-channel videos can be sequenced according to the priority information to obtain a sequencing result; and screening the sequencing result according to a preset rule to obtain a video to be played. By sequencing the priority information, the high-low order of the priority among the multiple paths of videos can be obtained, generally the videos can be sequenced from high to low, and the videos with the highest priority can be conveniently selected subsequently. The screening process can be specifically executed in the following various ways:
(1) and determining at least one video with the highest priority in the sequencing results as a video to be played. And selecting a plurality of videos with the top ranking from the sequencing result, wherein the specific number can be determined according to the number of videos which can be simultaneously displayed at the front end. In general, higher priority videos correspond to video content that is of interest or importance to the user.
(2) And determining at least one video with the highest priority and at least one video with the lowest priority in the sequencing results as videos to be played.
In practical use, there is also a need for comparison, that is, the most interesting and least interesting, most important and least important videos are needed at the same time, and the top videos and the last videos can be determined as videos to be played.
(3) And screening at least one video at intervals of a preset number of the sequencing results, and determining the video to be played.
It can be understood that, based on the above sorting result, the videos to be played can be selected according to the preset number interval, and the preset number can be changed in real time, that is, the sorting intervals between two selected videos to be played can be different, so that the purpose of giving consideration to videos of various degrees can be achieved.
Considering that there is a need for fixedly displaying some videos by a user, and therefore, the videos displayed at the front end cannot all be obtained by prioritization and filtering, the method may further include the following steps: and connecting the video channel corresponding to the video to be played to the corresponding playing channel according to the fixed mapping relation between the video to be played and the playing channel. Taking a monitoring system of a supermarket as an example, two fixed channels are fixed at the front end to map two fixed video sources, and the two fixed video sources can be two entrance and exit monitors of the supermarket.
After the multi-channel video playing method is completed, real-time refreshing can be carried out to change the video being displayed, and the method can also comprise the step of re-executing the step of determining and playing the video to be played when the playing time of the video to be played reaches the preset time length or when a refreshing instruction is received. The real-time refreshing supports timing refreshing or refreshing controlled by a user, and the method is executed again during refreshing to obtain a new video to be played and then play the video. The user may also modify the configuration instruction thereof, so as to change the focus of the currently played video, and the method may further include: and receiving a configuration change instruction input by a user, and determining target attribute information from the attribute information according to the configuration change instruction.
The following description takes a play scene of multiple paths of combined videos monitored by people flow/traffic flow as an example, and provides a method for maximally showing a video channel interested by a user on limited system resources. Referring to a flow diagram of the playing method of the multi-channel video, which is shown in fig. 3, the multi-channel video channels 1-N are shown, algorithm indexes are extracted from the video, then the algorithm indexes are input into the priority algorithm module, the priority algorithm module performs priority sorting and screening, and then screening results, that is, the channels 1, 2, 3 and M shown in the diagram, are output.
The indicators of interest to the user (i.e., the aforementioned target attribute information) for the flow of people or the flow of vehicles may include: pedestrian flow, vehicle flow, number of pushups, hot zones, number of objects detected, etc.
If the place where people flow appears is a retail store, the target attribute information can be obtained by a hotspot statistical method, and specifically comprises the number of staying people, the average staying time, the median of the staying time, the maximum staying time and the like. According to the hot zone statistics, corresponding priorities can be mapped to the image pickup devices (corresponding to the video sources).
