EXAMPLE III
The following describes the embodiment of the present invention in further detail with reference to a practical application scenario, as shown in fig. 4, an operator introduces four license plate parties, including huan number, bai wei tong, future and mango, to acquire a video, and the embodiment of the present invention includes the following steps:
step 401: determining the transmission quality of the live broadcast source in a normal state according to the historical record of the live broadcast source;
wherein, the determining the transmission quality when the live broadcast source is in a normal state includes:
determining a video type to which the currently playing video belongs, where the video type may include: movie channels, drama channels, music channels, news channels, sporting event live channels, and live/repeat/recorded video channels, etc.;
and determining the transmission quality of the determined video type when the video transmitted by the license plate party is in a normal state according to the history.
The server corresponding to the operator may determine, in advance, live broadcast quality of each live broadcast source corresponding to each program type and/or each television channel according to the introduced history records of all license plate parties, and sort all live broadcast sources according to the live broadcast quality to obtain a sorting result corresponding to each program type and/or each television channel.
In step 301, the history record may include data such as packet loss rate during live broadcasting, network delay during live broadcasting, live broadcasting definition, live broadcasting jitter, and abnormal live broadcasting alarm times.
In practical application, when a television channel/program type is created, a corresponding ID can be generated in a database, the ID has uniqueness and cannot be changed at will subsequently, and the ID corresponds to the network address information and the network port information of the transceiver, so that historical live broadcast data such as the live broadcast source packet loss rate, the network delay, jitter, the live broadcast abnormal alarm and the like corresponding to the television channel/program type can be obtained by detecting the corresponding transceiver network address under the ID entry and the network condition on the network port passage, and thus, the historical live broadcast data corresponding to each television channel/program type can be obtained.
For example: the television channel CCTV5, which can be used to identify the television channel CCTV5, can generate IDchannel00000001 in the database corresponding to CCTV5, which ID is not easily modified. After obtaining the ID corresponding to the television channel CCTV5, the transceiving end IP information and port information corresponding to the ID may be set, for example: the transceiving end IP information corresponding to the ID may be set as: x.x.x, the corresponding port information may be set to: 10000. with the above arrangement, it can be determined that from 10. x.x.x.x port: the stream received by 10000 is the stream of the television channel CCTV5 with the ID of channel 00000001. Therefore, by monitoring the IP and port, historical live broadcast data corresponding to the television channel CCTV5 is obtained.
After the historical live broadcast data of each live broadcast source corresponding to each television channel/program type is obtained, the live broadcast quality of each live broadcast source corresponding to each television channel/program type can be determined according to the obtained historical live broadcast data, wherein the live broadcast quality can be represented by specific numbers or quality grades.
In practical applications, a statistical period is determined, which may be a last period of time, for example, a last hour; in the live broadcast data, live stream cut-off is an important index, and therefore, once the live stream cut-off occurs, the live broadcast quality of the live source corresponding to the channel is poor. When the multiple live broadcast sources have over-cutoff in the latest hour for the same channel, respectively counting the cutoff duration, wherein the cutoff duration is longer and the quality is poorer; the short interruption time and the good quality. If no abnormal condition occurs in the live broadcast source within the last hour, the live broadcast source is determined to be 1 in quality level; or the like, or, alternatively,
a judgment criterion may be set, for example, at most: in the last hour, the jitter rate is less than 5%, or the packet loss rate is less than 5%, and when the single condition occurs, the quality level of the live broadcast source is 2; in the last hour, the jitter rate is more than 5% and less than 10%, or the packet loss rate in the last hour of the live broadcast process is more than 5% and less than 10%; or two situations that the jitter rate is less than 5% and the packet loss rate is less than 5% in the last hour occur simultaneously, the quality level of the live broadcast source is considered to be 3; in the last hour, the jitter rate is more than 10% and less than 20%, or the packet loss rate in the last hour of the live broadcast process is more than 10% and less than 20%, or the jitter rate in the last hour is more than 5% and less than 10% and the packet loss rate in the last hour is more than 5% and less than 10%, the quality of the live broadcast source is considered to be 4; when the packet loss rate is greater than 20% and less than 50% or the jitter rate is greater than 20% and less than 50% in the last hour, or the jitter rate is greater than 10% and less than 20% and the packet loss rate is greater than 10% and less than 20% in the last hour, the quality level of the live broadcast source is considered to be 5; when the packet loss rate is greater than 50% or the jitter rate is greater than 20% and less than 50% and the packet loss rate is greater than 20% and less than 50% in the last hour, the quality of the live broadcast source is considered to be 6; when the flow interruption situation occurs in the last hour, sorting is carried out according to the flow interruption time length in the last hour from 7 backwards, or,
after obtaining the packet loss rate, the jitter rate, the cut-off data and the like of the corresponding video source, performing weighting processing on the data, wherein the packet loss rate, the jitter rate, the cut-off data and the like can be set with different weight proportions to obtain weighted values, and determining the corresponding live broadcast quality according to the weighted values.
Step 402: determining a first time length according to the live broadcast quality of a live broadcast source;
in this embodiment, the first duration may be a time that is tolerant to abnormality thereof, for example, if the live broadcast quality of the live broadcast source currently used is far greater than that of other live broadcast sources, the time that is tolerant to abnormality thereof may be longer.
The time tolerance of the live broadcast source can be determined according to the live broadcast quality of the live broadcast source when the first time duration corresponding to the live broadcast source is determined, specifically, the time tolerance of the live broadcast source corresponding to the live broadcast source can be determined according to the live broadcast quality of the live broadcast source by related personnel, or the corresponding relation between the live broadcast quality of the live broadcast source and the time tolerance of the live broadcast source can be preset, and the server can determine the time tolerance of the live broadcast source corresponding to the time tolerance of the live broadcast source according to the preset corresponding relation.
For example, when the live broadcast quality level is 2, the user does not perceive intensely and can wait for 30 minutes, and if the user still cannot recover within 30 minutes, the user can switch to a live broadcast source with the live broadcast quality level of 1, that is, any abnormal live broadcast source does not exist; when the live broadcast quality level is 3, slight influence is generated on user experience, the setting is waited for 10 minutes, if the user still cannot recover within 10 minutes, at the moment, if the live broadcast source quality level is 1, the live broadcast source with the quality level of 1 is switched to. If the quality level of the live broadcast is not 1, checking whether the quality level of the live broadcast source is 2, and if so, switching to the live broadcast source with the quality level of 2; when the live broadcast quality is 4, setting the waiting time to be 1 minute; when the live broadcast quality is at a quality level of 5 and 5 or more, the waiting time is set to 5 seconds. By analogy, when the live broadcast source has abnormal conditions and needs to be switched, the quality grade state of the live broadcast source in the latest hour of other live broadcast sources is searched, and the live broadcast source with the highest quality grade is switched to.
Under one condition, when all live broadcast sources are abnormal and the current cut-off condition occurs within the last hour, at the moment, the cut-off occurs in a certain live broadcast source, and as long as the live broadcast source without the cut-off condition is searched and switched, emergency treatment is carried out.
It should be noted that the first time period or the tolerance of the abnormality may be determined according to the historical live broadcast quality of the live broadcast source, which is not limited in the embodiment of the present invention.
Step 403: when a live broadcast source currently playing a video is monitored to be in an abnormal state, recording the time length of the live broadcast source in the abnormal state, and when the time length of the abnormal state is longer than the first time length, determining other live broadcast sources based on a preset switching strategy;
the server corresponding to the operator can monitor the current live broadcast source, if the current live broadcast source is abnormal, the time for starting the abnormal live broadcast source to start is recorded, and if the current live broadcast source is not normal within the corresponding time (or times) for tolerating the abnormal live broadcast source, the server is automatically switched to other live broadcast sources with the best live broadcast quality;
for example, when it is monitored that the live broadcast quality corresponding to the current live broadcast source is not level 1, it may be determined that an abnormality occurs.
It should be noted that, when switching live broadcast sources, switching other live broadcast sources that have the highest quality level at this time and are not in a cut-off state at this time is performed.
Step 404: after determining and switching to other live broadcast sources with high transmission quality, continuing to play the live broadcast from the abnormal starting time;
wherein, the playing can be accelerated during playing, for example: 1.3 times, wherein the specific acceleration multiple can be set according to actual requirements, and when the playing time reaches the current time, the playing is carried out at a normal speed;
specifically, when a certain live source is abnormal, the server records the time point of the abnormal occurrence, and when the abnormal occurrence is not recovered after waiting for a certain time, the live source is switched according to the precondition. When the live broadcast source is switched to the normal live broadcast source, the terminal can jump out of the prompt box, so that a user can select to play from the current time point or to play when the live broadcast source is switched to the abnormal time. And if the broadcasting is carried out from the current time point, directly accessing the switched live broadcast source for broadcasting. If the user wants to play from the abnormal time point, the server reads the content stored before the live broadcast source, reads the content from the abnormal time point and sends the content to the user, and the user can select normal speed play or quick play for the content. If the user selects the fast playing, when the fast playing is carried out for a period of time and the live broadcasting time is caught up, the normal speed playing is carried out.
Step 405: after switching to other live broadcast sources, detecting the transmission quality of the live broadcast source before switching;
specifically, after switching to other live broadcast sources, if the live broadcast quality of the live broadcast source before switching is far greater than the historical live broadcast quality of the live broadcast source after switching, the live broadcast source before switching can be monitored, if the live broadcast source before switching is recovered to be normal, and the live broadcast source before switching is automatically switched back, and the length of the second time period can be in an inverse relation with the live broadcast quality difference value of the live broadcast source before switching and the live broadcast source after switching.
For example, if the original live broadcast source before switching is recovered to be normal for 10 minutes, and the quality level of the live broadcast source within 10 minutes is 1, switching back to the original live broadcast source; if the quality grade of the original direct broadcasting source is 2 and the quality grade of the switched direct broadcasting source is 3 after the original direct broadcasting source is recovered, switching the direct broadcasting source to the original direct broadcasting source 10 minutes after the original direct broadcasting source is recovered to be normal and the quality of the original direct broadcasting source is not deteriorated; and if the quality grade of the original live broadcast source is still lower than that of the switched live broadcast source after the original live broadcast source is recovered, the operation of switching back to the original live broadcast source is not implemented for the moment.
Step 406: and when no other live broadcast source is switched, playing the video or live broadcast which is interested by the user.
Specifically, the server corresponding to the operator may view data according to the history of the user, for example: the watching time, the watching place, the watching type and the like form the watching habit of the user, if the current live broadcast source is abnormal and other live broadcast sources which do not meet the conditions can be switched, for example, the live broadcast source has the exclusive broadcast right of a certain football match, and the live broadcast quality is poor due to more people watching the live broadcast content of the current live broadcast source; the method can switch to the live broadcast source playing other contents favorite by the user according to the watching habits of the user, at the moment, the user can be inquired whether to continuously watch the contents of the live broadcast source before switching, if the user wants to continuously watch the contents, the live broadcast source before switching can be monitored, and if the live broadcast source before switching is recovered to be normal and is kept stable in a period of time, the live broadcast source before switching is automatically switched back; and if the user does not want to continue watching, the current live broadcast source can be continuously used, and switching is not performed any more.
In practical application, in the process of watching the live broadcast service, the watching data of the user can be collected through the terminal. Such as a set-top box, a cell phone, etc. When a user watches the live broadcast service through the set top box, the live broadcast channel time lengths watched by the user are sequenced. The first 10 were taken and the viewing time was longest. For example, if the CCTV-5 time length is longest, the user is considered to prefer the sports channel and the program.
It should be noted that, in the embodiment of the present invention, in addition to the method for switching the live broadcast source when the live broadcast source is abnormal, optimized switching may also be performed, that is, every other time period, for example, every hour, a live broadcast source with the highest statistical quality in the previous period may be switched to, so as to improve user experience.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
