Detailed Description

Reference will now be made in detail to the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

The live broadcast method, system, and medium of the embodiments of the present application are described below with reference to the accompanying drawings.

Referring to fig. 1, the live broadcasting method in the embodiment of the present application includes the following steps 100 to 400.

S100, acquiring multi-channel live broadcast signals provided by different network service operators.

When slow live broadcasting is carried out, a video acquisition end generally acquires video pictures to obtain video data, then the video data is sent to a routing device as a live stream, the live stream is sent to a streaming media server through the routing device, and the streaming media server sends the live stream to a playing end for video playing.

The network service operator refers to an operator in the communication field of, for example, china mobile, china unicom, china telecom, china radio and television, and the like, the multiple live broadcast signals acquired by the streaming media server are from different operators respectively, and the multiple live broadcast signals correspond to the same video stream output by the same video acquisition end, that is, the video pictures acquired by the same video acquisition end are sent to the streaming media server through different operators respectively, and the streaming media server selects one of the multiple live broadcast signals from the received multiple live broadcast signals to play.

And S200, determining available signals from the multipath live broadcast signals and the pad signals.

The gasket signal is a signal read from a gasket file, and the gasket file is pre-recorded audio and video content, so that the gasket signal is a pre-recorded audio and video signal. The shim file may be stored in a shim server, which may be part of a streaming media server. When receiving multiple live broadcast signals, the streaming media server needs to determine all available signals from the live broadcast signals and preconfigured pad signals, where the available signals refer to the live broadcast signals that can be normally received and used.

And S300, determining an optimal signal according to the priority of the available signals.

After determining all the available signals, the streaming server determines the optimal signal from all the available signals, which may be evaluated in terms of signal quality of the available signals.

Because the signal provided by the operator may be unstable and even cut off, when the current optimal signal is unstable, signal failure or other conditions that cause video quality to be reduced and even cannot be played, the streaming media server can immediately re-determine the available signal from the multiple live broadcast signals and the pad signal, and determine a new optimal signal according to the priority of the newly determined available signal, so that when the current live broadcast signal being played is cut off due to failure or other reasons, the live broadcast signals provided by other operators can be used for continuous playing, and the video content before and after continuous playing can have continuity.

It can be understood that, in step 200, the streaming media server may determine the available signals in real time, and determine new optimal signals in real time according to the priorities of the newly determined available signals, on one hand, when the available state of any live broadcast signal or shim signal changes, the streaming media server can immediately determine which of the changed available signals are available, and then when the current optimal signal is unstable or has a signal fault, the streaming media server may determine new optimal signals from the newly determined available signals, so as to guarantee the live broadcast signals; on the other hand, when the available signal with the priority higher than the current optimal signal is recovered to be communicated, the streaming media server can immediately re-determine the optimal signal, so that the available signal with the highest priority can be used as the optimal signal to be live broadcast, and better video content and video quality can be provided.

S400, sending the optimal signal to a playing end for playing.

After all the optimal signals are determined, the streaming media server sends the optimal signals to a playing end of a user so as to play video pictures acquired by a video acquisition end for the user to watch.

The following is a description of the live broadcast method of the present embodiment by taking the example of landscape slow live broadcast.

The video acquisition end comprises a camera which is installed at a higher position of a certain building and is used for acquiring video pictures of a target area on the ground in real time. The camera is connected with a double-card wireless router R, and after the camera is opened, the collected video pictures are sent to the router R. The router R supports installation of double sim cards, card slots of flow cards of two operators are built in the router R, and the router R is respectively distributed with an IP by two different operators A and operators B, so that two external IPs are shared to output live streams related to the video pictures, a wireless long-distance data transmission function is provided for users, and a double-link backup function is provided. The method comprises the steps that a gasket file is stored in a streaming media server S, after the server S receives live broadcast signals forwarded by an operator A and an operator B, the two paths of live broadcast signals and gasket signals are determined to be available signals, and therefore the server S determines that the live broadcast signals of the operator A are optimal signals according to the priority of the three paths of signals, and sends the live broadcast signals of the operator A to an intelligent television terminal to be played so that a user can watch scenery of a target area.

The streaming media server S monitors the communication state between the streaming media server S and the operator A and the communication state between the streaming media server S and the operator B, network communication between the streaming media server S and the operator A is disconnected at the moment T1, the signal of the operator A cannot be acquired, and at the moment, the available signal is the signal of the operator B and the gasket signal, so that the signal of the operator B is used as a new optimal signal according to the priority and is immediately switched to the signal of the operator B to be played, and interruption of a playing picture is avoided.

Then, at time T2, the network communication between the server S and the operator B is also disconnected, and the signals of the operator a and the operator B cannot be acquired, and at this time, the available signal is the shim signal, so that the shim signal is used as a new optimal signal and immediately starts to be played, and the shim signal is a video picture of the same target area recorded in advance, thereby avoiding interruption of the played picture.

And then, at the time of T3, network communication between the server S and the operators a and B is restored, signals of the operators a and B can be acquired, and at this time, all three signals are available signals, so that the signal of the operator a with the highest priority among all available signals at present is used as an optimal signal, and is immediately switched to the signal of the operator a for playing.

In some embodiments, the priority of the available signals is determined by: firstly, evaluating signals provided by an operator in available signals according to a priority evaluation item to obtain an evaluation result, wherein the priority evaluation item comprises network quality and/or traffic cost. The priority of the operator provided signal is then determined in dependence on the evaluation result, wherein the priority of the shim signal is lowest.

The priority rating term is mainly adapted to the operator's signals and not to the shim signals, which have a lower priority than all the operator's signals. In the priority evaluation item, the network quality refers to the signal quality between the server S and the operator, and the traffic cost refers to the cost to be paid for using the service of the operator, for example, the cost per megatraffic. The priority evaluation item used in evaluating the priority of the available signal may be selected according to the emphasis point, for example, when the cost is emphasized, only the traffic cost may be selected as the priority evaluation item, when the signal quality is emphasized, only the network quality may be selected as the priority evaluation item, and when the emphasis is balanced, both the network quality and the traffic cost are used as the priority evaluation item.

Assuming that the priority evaluation item includes both network quality and traffic charges, and the currently available signals include operator a signals, operator B signals, and shim signals, the available signals participating in the evaluation include operator a signals ca and operator B signals cb. The comprehensive evaluation result of each evaluation item can be characterized by a level, and the lower the level value is, the higher the priority is, for example, the comprehensive evaluation result of the network quality and the traffic cost of the signal ca is first level, and the comprehensive evaluation result of the signal cb is second level, and the priority of the signal ca is higher than the priority of the signal cb. The comprehensive evaluation result of each evaluation item can also be characterized by a score, and the higher the grade is, the higher the priority is, for example, the comprehensive evaluation result of the network quality and the traffic cost of the signal ca is 84 scores, and the comprehensive evaluation result of the signal cb is 76 scores, so that the priority of the signal ca is higher than that of the signal cb.

Since the priority of the shim signal is the lowest, if the evaluation result is represented by rank, the rank value of the shim signal is the highest allowable rank value, and if the evaluation result is represented by score, the score of the shim signal is 0.

Specifically, the comprehensive evaluation result of the available signal can be obtained by calculating the score of each evaluation item and the weight of the evaluation item. The streaming media server S may set a corresponding weight for each evaluation item in advance, assuming that the weight of the network quality is 0.5 and the weight of the traffic cost is 0.2. The server S monitors the communication state of the signal ca and the signal cb to obtain that the network quality of the signal ca is 80 minutes and the network quality of the signal cb is 70 minutes, which indicates that the signal quality of the signal ca is better than that of the signal cb. Moreover, since the same video stream is transmitted and the traffic unit price of the operator is usually fixed, the traffic fee for obtaining the signal ca is 70 points, and the network quality of the signal cb is 75 points, which means that the traffic charging standard of the operator a is slightly more expensive than that of the operator B. At this time, the total evaluation result of the available signal ca is 0.5 × 80+0.2 × 70=54, and the total evaluation result of the available signal cb is 0.5 × 70+0.2 × 75=50, so that the priority of the available signal ca is higher than that of the available signal cb.

It can be understood that, the operator corresponding to the available signal may also be evaluated according to the service quality of the operator to obtain an evaluation result, and the priority of the signal provided by the operator is determined according to the evaluation result of the available signal and the evaluation result of the operator. The quality of service refers to the response speed of an operator and the expertise in solving a problem after a network problem occurs. Specifically, the weight of the service quality may be 0.3, the service quality of different operators is usually fixed, and therefore the service quality scores of different operators are also usually fixed, so that the service quality of the obtained signal ca is 80 minutes, the network quality of the signal cb is 60 minutes, and then the comprehensive evaluation result of the available signal ca is 0.5 × 80+0.2 × 70+0.3 × 80=78, and the comprehensive evaluation result of the available signal cb is 0.5 × 70+0.2 × 75+0.3 × 60=68, so that the priority of the available signal ca is higher than that of the available signal cb.

In some embodiments, in the step 300, that is, in determining the optimal signal according to the priority of the available signals, if the determined optimal signal is a live signal, the live broadcast method further includes: and generating a gasket file according to the optimal signal.

The shim file is used to generate shim signals that are generated when the shim server reads the shim file. The shim signals are configured in advance, so the content of the shim signals can specifically adopt the content of the previous live broadcast signals, that is, when the currently determined optimal signals are the signals of an operator, the streaming media server S sends the optimal signals to the playing end for playing, records the optimal signals and generates a shim file, for example, the optimal signals can be recorded within a period of continuous time, and a shim file capable of playing for a certain time is generated.

In some embodiments, the manner of generating the shim file according to the optimal signal in step 300 may specifically be: and recording the optimal signal from the preset moment until the preset duration is reached to obtain the gasket file.

The preset time and the preset duration can be set according to needs, and the preset time can be selected at the time when the scenery in the target area is the most beautiful, for example, 12 noon on the first natural day of a certain month is selected: 00 as the preset time, the preset duration may be set to be an expected approximate time of equipment maintenance, for example, one hour, since the gasket file needs to be maintained for the operator's flow-out trouble when the gasket file is played, and thus the gasket file needs to be continuously played until the maintenance is completed. Specifically, if the optimal signal is the signal of the operator a at the preset time, the streaming media server S starts to record the shim file by using the optimal signal from the preset time, and continuously records the shim file for one hour, so as to obtain the shim file with the playing time of one hour.

In some embodiments, there are a plurality of preset times, and all the preset times correspond to a plurality of different time periods.

The preset time is set under a plurality of different time periods respectively, the optimal signal is recorded at each preset time to obtain the gasket file, and due to the difference of the time periods, the picture content played by the gasket file is different, so that different appearances of the target area under different time periods can be displayed conveniently. Specifically, for example, a preset time is set in each of four seasons of spring, summer, autumn, and winter, the four seasons may be divided by a lunar calendar division method, that is, the four seasons are spring 1 to 3 months, summer 4 to 6 months, autumn 7 to 9 months, and winter 10 to 12 months, and the preset time may be selected as a certain time in the first natural day of each season, that is, a certain time in 1 month 1 day, 4 month 1 day, 7 month 1 day, and 10 month 1 day.

When determining the available signal from the multipath live broadcast signal and the shim signal in step 200, the shim signal is obtained from the shim file at the corresponding time interval. In addition, after the gasket file is generated according to the optimal signal, the existing gasket file in the corresponding time period can be replaced by the newly generated gasket file.

Specifically, an optimal signal of one hour is recorded from noon H of 1 month and 1 day of Y year to obtain a shim file F12, and the file F12 is sent to a shim server to replace the shim file F11 recorded from 1 month and 1 day of the previous year (Y-1 year), that is, delete the file F11, so as to save the storage space occupied by the shim file. Then, before H noon in 3/1/3 of the year, if the signals of the operator a and the operator B are both cut off, the gasket file F12 is read to obtain the gasket signal for playing, so that the environmental climate in the played content is the same as the current actual environmental climate. Recording an optimal signal for one hour from noon H of 3 month 1 day of Y year to obtain a gasket file F22, sending the file F22 to a gasket server to replace the gasket file F21 recorded from 3 month 1 day of Y-1 year, and reading the gasket file F22 to obtain a gasket signal for playing before the noon H of 6 month 1 day of Y year if signals of an operator A and an operator B are cut off. Recording gasket files in autumn and winter, replacing the gasket files, selecting the gasket files, and the like.

In some embodiments, in all different time periods corresponding to all the preset times, each time period corresponds to a plurality of preset times, and the plurality of preset times corresponding to the same time period are distributed in different time periods of the natural day. When determining the available signal from the multiple live broadcast signals and the shim signals in step 200, the shim signals are obtained from the shim files at the corresponding time intervals.

In the four seasons, each season is provided with a plurality of preset moments, and the preset moments of each season are distributed in different time periods of a day, for example, each season is provided with four preset moments which are respectively set in early morning, midday, evening and night.

Specifically, an optimal signal of one hour is recorded from the early morning H1 time of 1 month and 1 day of the Y year to obtain a shim file F111, the file F111 is sent to a shim server and replaces the file recorded in the early morning H1 time of 1 month and 1 day of the Y-1 year, and the service time of the shim file F111 is from the H1 time to the H2 time of each natural day between 1 month and 1 day of the Y year and 3 months and 1 day.

Recording an optimal signal of one hour from the midday H2 time of 1 month and 1 day of Y year to obtain a gasket file F112, sending the file F112 to a gasket server and replacing the file recorded at the midday H2 time of 1 month and 1 day of Y-1 year, wherein the service time of the gasket file F112 is from the H2 time to the H3 time of each natural day between 1 month and 1 day of 3 months and 1 day of Y year.

Recording an optimal signal for one hour from the early evening H3 time of 1 month and 1 day of Y year to obtain a gasket file F113, sending the file F113 to a gasket server and replacing the file recorded at the early evening H3 time of 1 month and 1 day of Y-1 year, wherein the service time of the gasket file F113 is from the H3 time of each natural day to the H4 time between 1 month and 1 day of Y year and 3 months and 1 day.

Recording an optimal signal of one hour from the night H4 moment of 1 month and 1 day of Y year to obtain a gasket file F114, sending the file F114 to a gasket server and replacing the file recorded at the night H4 moment of 1 month and 1 day of Y-1 year, wherein the service time of the gasket file F114 is from the H4 moment to the H1 moment of each natural day between 1 month and 1 day of 3 months and 1 day of Y year.

Suppose that at a certain time of morning of 2 months and 5 days of Y year, the signal of the operator a being played is cut off, the available signals determined at this time are the signal of the operator B and the shim signal of the shim file F111, and the signal of the operator B is selected for playing, and if the signal of the operator B is cut off, the shim signal of the shim file F111 is played. Assuming that all the carrier signals are simultaneously interrupted at a certain time in the afternoon of 26/2/Y of Y year, the determined available signals are only the shim signals of the shim file F112, and thus the shim signals of the shim file F112 are played.

And for the summer, autumn and winter of Y year, and so on, respectively recording the optimal signals at the time of H1-H4 of the first natural day of the season, and replacing the gasket files in the corresponding season of Y-1 year and at the corresponding time.
