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.
Fig. 1 is a schematic flow chart of a video stream processing method according to the present invention. Referring to fig. 1, the video stream processing method provided by the present invention includes:
s110, acquiring a terminal identifier and a video playing parameter corresponding to a video stream to be processed;
s120, acquiring authorization for playing the multicast video stream according to the terminal identification, and switching the to-be-processed video stream into the multicast video stream;

wherein the parameter values comprise single parameter values and/or composite parameter values.
The execution main body of the video stream processing method provided by the invention can be a video stream processing system. The video stream processing system supports processing and switching of video streams in different networking scenes and different intelligent terminals by taking an area as a unit.
The following describes the technical solution of the present invention in detail by taking a video stream processing system in a home as an example to execute the video stream processing method provided by the present invention.
It should be noted that the video stream processing system using a home as a unit may include an intelligent terminal processing module, an intelligent networking terminal, and an intelligent gateway distribution module.
The existing universal intelligent terminal processing module is located on an intelligent terminal, a wireless or wired mode is generally adopted to access an intelligent networking terminal, the intelligent networking terminal is usually composed of terminals with wired or wireless coverage capabilities such as a router, a power modem and a POE (power over Ethernet) routing switch, the general router, the power modem and the POE routing switch adopt a wired mode, and devices such as an MESH (MESH wireless) router and a wireless repeater adopt a wireless mode to access an intelligent gateway distribution module. And a plurality of intelligent terminals, a plurality of intelligent networking terminals and an intelligent gateway distribution module are usually arranged in a family, along with the increase of the area in the family, the number of various terminals is greatly increased, the networking topology and the environment are also very complex, and the number of equipment is also greatly increased. Meanwhile, the intelligent networking terminal also has different working modes such as bridging, routing and the like, so that the traditional multicast and unicast working modes can not effectively carry out cooperative work, and the optimal realization effect can not be achieved.
Optionally, in step S110, the intelligent terminal processing module of the video stream processing system obtains the terminal identifier and the video playing parameter corresponding to the video stream to be processed. The video stream to be processed can comprise various different unicast and multicast video code streams; the home intelligent terminal processing module is positioned at the point closest to the user side, and can feed back the video playing condition and the terminal load condition of the terminal in real time, so that the home intelligent terminal processing module needs to accurately feed back corresponding data and provide corresponding data reference for the gateway distribution module; the terminal identification comprises related information such as equipment type, model, software and hardware parameters, multicast or unicast supporting condition, region and the like; the video playing parameter is a parameter reflecting the video playing state.
Optionally, in step S120, the intelligent networking terminal of the video stream processing system authorizes playing of the multicast video stream according to the terminal identifier reported by the intelligent terminal processing module. After the authorization authentication is passed, the multicast video stream can be played, and only the unicast video stream can be played without passing the authorization authentication.
And for a common terminal which does not support the processing module of the household intelligent terminal, the common on-demand program source can be watched, but the multicast live broadcast-like experience cannot be obtained. And after the authentication and authorization of the processing module supporting the home intelligent terminal pass, the multicast video stream is played on the live streaming by default.
Optionally, in step S130, the intelligent gateway distribution module confirms that the parameter value of the video playing parameter exceeds the corresponding preset parameter threshold, and the intelligent gateway distribution module notifies the intelligent terminal processing module to switch the multicast video stream to the unicast video stream. Wherein the parameter values comprise single parameter values and/or composite parameter values.
When the flow of the multicast video stream reaches a certain threshold pressure, that is, the parameter value of the video playing parameter exceeds the corresponding preset parameter threshold value, it indicates that the current system generates network jitter, networking environment or abnormal changes of other video playing parameters. At this time, in order to ensure the playing of the video stream, the intelligent terminal processing module can be actively switched to a unicast video stream mode, the influence of network jitter on the video stream is reduced through caching, and meanwhile, the intelligent networking terminal and the intelligent gateway distribution module are informed, so that the multicast replication overhead is reduced.
The intelligent gateway distribution module carries out interactive identification on the intelligent terminal accessed below the intelligent gateway distribution module, informs the intelligent networking terminal of the lower hanging and the intelligent terminal of whether the upper connecting equipment supports multicast or not and informs a corresponding switching identification mechanism, and is convenient for the lower hanging equipment to know the network topology and the supporting condition of the lower hanging equipment; the intelligent gateway distribution module also carries out multicast distribution on the accessed household intelligent networking terminals or the directly connected household intelligent terminal processing modules, and simultaneously interacts with the intelligent terminals and the intelligent networking terminals, and actively judges to carry out household on-demand and multicast code stream switching according to the number, types and running conditions of the household intelligent terminals and the intelligent networking terminals. When the network quality problem is found, the intelligent gateway distribution module can timely inform the intelligent networking terminal and the intelligent terminal processing module under the intelligent gateway distribution module to switch. When the change of the networking environment is found, the intelligent networking module and the intelligent terminal processing module are timely notified to carry out state detection and switching.
According to the video stream processing method provided by the invention, the authorization for playing the multicast video stream is obtained through the terminal identification corresponding to the video stream to be processed, and the default multicast video stream is automatically switched to the unicast video stream under the condition that the video playing parameter corresponding to the video stream to be processed is judged to exceed the corresponding preset parameter threshold value, so that the corresponding processing can be carried out according to the playing condition of the video stream to be processed, the self-adaptive video stream processing and switching can be realized, the system overhead is reduced, and the user experience is improved.
In one embodiment, the video playing parameters include: at least one of packet loss rate, blue screen parameter, screen splash parameter, time delay, real-time code rate, network jitter parameter and disorder parameter;
the single parameter value is the value of any one video playing parameter;
the comprehensive parameter value is the sum of values of a plurality of video playing parameters.
Alternatively, the effect of video playing or network access is not single parameter determinable, and therefore the influence of the single parameter and the comprehensive parameter needs to be comprehensively considered. The video playing parameters may be parameters reflecting video playing states of different dimensions, including: parameters of subdivision scenes such as packet loss rate, blue screen parameters, screen splash parameters, time delay, real-time code rate, network jitter parameters, disorder parameters, small packet loss rate and large packet loss rate can be adjusted in a background and customized by a user according to configuration, cache size, network bandwidth and the like of a terminal. The single parameter value is the value of any one video playing parameter, and the comprehensive parameter value is the sum of the single parameter values of a plurality of different video playing parameters. The parameter value of each video playing parameter has a corresponding preset parameter threshold value.
According to the video stream processing method provided by the invention, the video stream can be adjusted in real time according to the video playing state by setting the preset parameter threshold value for different video playing parameters.
In an embodiment, the determining that a parameter value of the video playing parameter exceeds a corresponding preset parameter threshold value, and switching the multicast video stream to the unicast video stream includes:
confirming that the single parameter value exceeds the corresponding preset parameter threshold value, and switching the multicast video stream into the unicast video stream;
and/or switching the multicast video stream into the unicast video stream after confirming that the comprehensive parameter value exceeds the corresponding preset parameter threshold value.
Optionally, the intelligent gateway distribution module performs parameter evaluation on parameters such as packet loss rate, blue screen/screen splash parameters, and network speed jitter, and notifies the intelligent terminal processing module to perform corresponding switching operation when one or more parameters reach a threshold.
An example of a video playback parameter evaluation process is as follows:
setting a packet loss rate parameter as A, setting the parameter as 0.5 when the packet loss rate is greater than 0.5%, setting the parameter as 1 when the packet loss rate is greater than 1%, linearly changing the packet loss rate between 0 and 1, and setting a preset parameter threshold value as 0.5.
Setting the blue screen/screen-splash parameter as B, when the duration time exceeds 5 seconds, the duration time is 0.5, when the duration time exceeds 10 seconds, the duration time is 1, the blue screen/screen-splash parameter is linearly changed between 0 and 1, and the preset parameter threshold value is 0.5.
Setting a wire speed jitter parameter as C, setting the wire speed jitter parameter as 0.5 when the jitter exceeds 50%, setting the wire speed jitter parameter as 1 when the jitter exceeds 100%, linearly changing the wire speed jitter parameter between 0 and 1, capping when the wire speed jitter parameter reaches 1, and setting a preset parameter threshold value as 0.5.
When the intelligent gateway distribution module confirms that the single parameter value exceeds the preset parameter threshold value, namely a > =0.5 or B > =0.5 or C =0.5, it is known that the network quality is poor, and at this time, the intelligent terminal processing module is notified to switch the multicast video stream into the unicast video stream.
When the intelligent gateway distribution module confirms that the comprehensive parameter value exceeds a preset parameter threshold value, namely A + B + C is greater than 0.5, the network quality is known to be poor, and at the moment, the intelligent terminal processing module is informed to switch the multicast video stream into the unicast video stream.
According to the video stream processing method provided by the invention, the advantages of small multicast video stream time delay and low network load can be exerted to the maximum extent aiming at different video playing parameters by setting the preset parameter threshold values for different video playing parameters and judging, and the advantages of large cache support of the unicast video stream, network jitter, blue screen avoidance and the like can be realized.
In one embodiment, the video stream processing method further includes:
and under the condition that the number of terminals playing the unicast video stream exceeds the preset threshold number, confirming that the parameter value of the terminal does not exceed the preset parameter threshold value, and switching the unicast video stream corresponding to the terminal into the multicast video stream.
Optionally, when the number of terminals under the intelligent networking terminal exceeds a preset threshold number (for example, the number of terminals accounts for 40% of the total number of terminals under the intelligent networking terminal), it is determined that a parameter value of the terminal does not exceed a preset parameter threshold, that is, when the current terminal does not have a network quality problem, the intelligent gateway distribution module notifies the intelligent terminal processing module to switch the unicast video stream to the multicast video stream.
The intelligent networking terminal interacts with the intelligent terminal processing module, reports the home networking topological environment including the conditions of adopting a routing mode or a bridging mode, whether a two-layer switching device or a direct connection device is adopted in the middle, whether multilayer cascade connection exists and the like, and completes multicast authentication and authorization of the intelligent terminal processing module under the intelligent networking terminal when the intelligent networking terminal is in the routing mode. Under the general condition, if a user uses common networking equipment and sets the common networking equipment into a routing mode, the intelligent terminal under the common networking equipment often cannot obtain the multicast authentication authorization of the gateway, the intelligent networking terminal supports the multicast authentication authorization of the household intelligent terminal processing module under the routing mode, reports the relevant information to the intelligent gateway distribution module, supports the flexible configuration of a networking environment for the user, and simultaneously enables the household intelligent terminal processing module under the conditions of multi-level networking and the like to perform normal multicast and on-demand switching so as to obtain the best play experience and reduce the load.
According to the video stream processing method provided by the invention, under the condition that the number of the terminals exceeding the preset threshold is judged to switch the multicast video stream into the unicast, the intelligent terminal switched into the unicast is switched back to the multicast under the condition that the intelligent terminal accords with the preset parameter threshold, so that the scale pause phenomenon can be solved in advance, the switching is avoided after long-time pause, and the unicast flow pressure and the household flow bandwidth are reduced.
In one embodiment, the switching the multicast video stream to the unicast video stream comprises:
and switching the unicast video stream into the multicast video stream under the condition that the parameter value does not exceed the preset parameter threshold value.
Optionally, the intelligent terminal processing module determines that the parameter value does not exceed the preset parameter threshold, that is, the parameter value is restored to be below the preset parameter threshold at this time, and the intelligent gateway distribution module notifies the intelligent terminal processing module to automatically switch the unicast video stream back to the multicast video stream. That is, when the network quality recovers to normal, the intelligent terminal processing module switches back to the multicast video stream mode at a suitable time for playing the video stream (for example, when the video is switched from channel to channel, and the video is paused or switched), and notifies the intelligent networking terminal and the intelligent gateway distribution module.
According to the video stream processing method provided by the invention, the unicast video stream is switched back to the multicast video stream under the condition that the parameter value does not exceed the preset parameter threshold value, namely the network quality is recovered to be normal, so that the play mode of the non-perception transition video stream is realized, and the live broadcast cost is reduced.
In one embodiment, the video stream processing method further includes:
and under the condition that the authorization for playing the multicast video stream is invalid and/or the comprehensive parameter value is reduced, switching the video stream to be processed into a unicast video stream.
Optionally, for a video source supporting unicast playing only or a video source supporting both multicast and unicast originally, when the multicast video stream authorization suddenly fails or the comprehensive parameter value is decreased, the intelligent gateway distribution module may notify the intelligent networking terminal therebelow to switch to the unicast video stream mode, and the intelligent networking terminal may notify the household intelligent terminal processing module therebelow to switch to the unicast video stream mode.
The video stream processing method provided by the invention can effectively cooperate the multicast video stream and the unicast video stream by adjusting the resource of the multicast video stream.
In one embodiment, the video stream processing system may further include a cloud-based intelligent processing platform.
Optionally, the cloud intelligent processing platform may count and automatically analyze the support condition of the down-hanging device. When a problem occurs on the platform side, the switching of the hanging-down equipment is actively informed, and in order to reduce interaction and reduce cost, the corresponding intelligent gateway distribution module or the intelligent networking module is only required to be informed, and the interaction notification can be automatically carried out on the hanging-down equipment. And issuing corresponding comprehensive parameters according to the hardware configuration of each home gateway and the networking terminal, wherein the comprehensive parameters are used as a reference for adjusting multicast and unicast strategies in the home and the family.

and after the authentication and authorization are passed, the intelligent terminal processing module defaults to carry out multicast request and play on the live broadcast traffic. When the parameter value of the video playing parameter reaches the preset parameter threshold value, the intelligent terminal processing module can be actively switched to a unicast mode, and meanwhile, the intelligent networking terminal, the intelligent gateway distribution module and the cloud intelligent processing platform are informed.
