Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments 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.
In a first aspect, an embodiment of the present invention provides a method for optimizing a live broadcast service in a scenic spot, as shown in fig. 2, including:
s101, acquiring current weather environment information of an area where a live broadcast system is located;
s102, if the weather environment information is judged to be the weather environment information which can influence the normal live broadcast of the video acquisition equipment in the live broadcast system, replacing the live broadcast image of the current video acquisition equipment with the video image acquired in the preset associated time period to play.
The embodiment of the invention provides a scenic spot live broadcast service optimization method, wherein a live broadcast system control device can acquire the weather environment information, and if the current weather is judged to be severe weather which can influence the normal live broadcast of a video acquisition device, a video image acquired at a preset certain associated time period is used for replacing the live broadcast for playing. Therefore, the defect that the traditional live broadcast scheme can only mechanically live broadcast the currently acquired pictures is overcome, and the user can normally watch the video images which are not influenced by the weather under the severe weather condition.
The live broadcast system can be a live broadcast system applied to a scenic spot, a plurality of video acquisition devices in the scenic spot live broadcast system can be distributed at different positions of the scenic spot respectively, and images acquired by the video acquisition devices are required to be transmitted to a control center of the live broadcast system; the weather environment information acquisition can be specifically obtained by connecting a server capable of issuing weather information through the internet; the weather environment influencing normal live broadcast can include weather conditions such as rain, snow, strong wind, typhoon, cloud, fog, haze, sand storm and the like.
Further, the association period here may be set according to actual circumstances. For example, may be a period of time that is different in date from the current live period, but the same in time period; or may be the same date as the current live session but for a different time period (e.g., the first half hour of the day, etc.).
In specific implementation, there may be a plurality of ways to obtain the weather environment information of the area where the live broadcast system is located in step S101. For example, current weather environment information of the area where the live broadcast system is located is periodically acquired (for example, once in 30 minutes). Or the current weather environment information of the area where the live broadcast system is located is obtained when a live broadcast request is received, wherein the live broadcast request can be a live broadcast request aiming at video acquisition equipment in a certain area or a certain area in the live broadcast system.
In specific implementation, there may be a plurality of different implementation manners for determining whether the weather environment information is weather environment information that can affect normal live broadcast of the video capture device in step S102. One of the optional implementations is:
and S1021, judging whether the weather environment information is severe weather environment information capable of influencing normal live broadcast of the video acquisition equipment according to the type and the installation position of the video acquisition equipment.
Particularly, whether the weather condition influences the live broadcast effect and needs to distinguish the live broadcast video acquisition device is certain, and whether each live broadcast signal can be influenced needs to be judged respectively to correspond different camera types and mounting positions. For example, some cameras are fixed angle cameras, so that it is difficult to influence normal live broadcast in windy weather. For another example, a camera at the top of a Taishan mountain can be influenced by strong wind, fog or cloudy weather, but a camera at the foot of the Taishan mountain can not be influenced by cloudy weather; outdoor cameras can be affected by strong winds, but indoor cameras cannot.
In order to facilitate the judgment of whether the current weather influences the normal live broadcast of a certain video acquisition device in actual conditions, the influence conditions of various weathers on various video acquisition devices shown in table 1 can be set in advance according to the type and the installation position of a video acquisition device, and a condition table is stored.
After a user watches a request of a certain video acquisition device, whether the channel live broadcast signal is influenced or not is judged according to the ID of the video acquisition device and the current weather condition.
In specific implementation, before the step of playing the video image acquired in the preset associated time period instead of the live image of the current video acquisition device, the method further includes:
judging whether a video image acquired by the video acquisition device in a previous preset associated time period is stored may specifically include:
s102a, judging whether a video image which is acquired by the video acquisition equipment in a previous preset associated time period and meets a set condition is stored; here, the setting conditions may be: and the weather environment information corresponding to the preset associated time period is the weather environment information which does not influence the video acquisition equipment to carry out normal live broadcast.
It is understood that the video captured by the video capture device in the relevant time period may be affected by weather to make the video frame unclear, and at this time, if the frame is replaced by the current live frame, the good viewing effect is still not achieved. Therefore, it is also necessary to determine whether the weather condition corresponding to the associated time period can affect the normal live broadcast.
Here, the manner of acquiring weather corresponding to the associated time period may be: acquiring the weather of the associated time period through the Internet; or storing the weather condition in the database each time the weather condition is acquired, and directly calling the weather condition corresponding to the associated time period in the database when the weather condition needs to be judged.
Further, the preset association period may be a plurality of association periods, and the step S102a may specifically include:
s102a1, judging whether video images which are acquired by the video acquisition equipment in each associated time period and meet set conditions are stored according to the sequence of preset associated time periods; and the preset sequence of the associated time periods is from near to far away from the current moment.
Specifically, assume that the plurality of associated time periods are the same time period for each day of the first 5 days. If the current weather influences live broadcast, whether the video images collected in the previous day are stored or not is judged, and whether the video images in the previous 1 day are clear or not is judged, namely whether the video images in the previous day are influenced by the weather conditions in the previous day or not.
And if the image of the previous day is stored and the image picture quality is good, directly taking the video image of the previous day as the image for replacing the live broadcast image. If the image of the previous day is not stored or the image quality of the previous day is not good, whether the image is stored and the image quality of the previous day are continuously judged until the stored image meeting the conditions or all the associated time periods within 5 days are found and judged.
It can be understood that, in an actual situation, there may be a case where no video image is stored or a video image meeting the condition is not stored, and then the method provided by the embodiment of the present invention further includes:
and S104, if the video image does not exist, playing the live image of the current video acquisition equipment.
A complete implementation flow of the method provided by the embodiment of the present invention can be seen in fig. 3. Since the respective steps have been described in the foregoing, they are not described in detail herein.
The following two examples are presented to illustrate the methods provided by embodiments of the present invention:
example 1:
the camera that can live sunrise is equipped with on the top of Taishan mountain, but the serious cloudy weather of some seasons will shelter from the camera, and the video that this camera was live and was recorded in the day before can synchronous broadcast this moment, makes the user watch sunrise in the same sunrise time basically today. And if the first three days are cloudy, playing the video three days ago.
Example 2:
some scenic spots have performance programs in the afternoon of every wednesday, if the performance programs cannot be shot by the cameras in the scenic spots due to severe haze of a certain wednesday, the program records of the same camera in the last wednesday are played. If the weather station monitors that strong wind blows away haze at a certain moment, the weather station can replace the haze with the live broadcast image at that moment.
Therefore, the method provided by the embodiment of the invention can be used for carrying out adaptive adjustment according to different weather conditions, ensures the good live broadcast effect and improves the impression experience of users.
