Influence.
For the ease of those skilled in the art understand that the present invention, disappears to direct broadcasting room provided by the invention below in conjunction with attached drawing
The filter method of breath lays down a definition explanation.
Referring to Fig. 1, it illustrates a kind of filter method flow chart of direct broadcasting room message provided in an embodiment of the present invention, the party
Method is applied to live streaming client, and message is buffered in the caching of live streaming client place terminal, and method may include：
S101：The weighted value of message in being cached, the importance of the weighted value characterization message.
In practical application, the type of message of direct broadcasting room is varied, such as：Common message, fly screen message, red packet message,
Upper and lower wheat message etc., its importance value of different types of message is also different, can be inhomogeneity to distinguish the significance level of message
The message of type presets weighted value.Wherein, the transmission for flying screen message, the message such as red packet message needs to buy corresponding virtual coin and just may be used
It sends, the importance value of this kind of message is higher than common message.Wherein, the weighted value of message can obtain in the following manner in caching
It takes.
In some embodiments, while user sends message by the way that client is broadcast live, it is corresponding to send the message
Weighted value, and in the buffer with message storage, subsequently to obtain the weighted value of the message from caching.
In some embodiments, when receiving the message that other users are sent by client as user, in buffered message
While, the weighted value of the message is calculated, which can together store in the buffer with message, convenient subsequently from caching
Obtain the weighted value of the message.
In view of the factor influenced on message severities is more, for example, the value of message, the length of message, message is slow
Deposit time etc..Based on this, present embodiments provide a kind of message weight value calculating method, in the computational methods, weighted value with
The make purchases worth more of message and the length of message are directly proportional, are inversely proportional with the time of message caching.
When concrete application, following calculation formula may refer to：
Wherein, WiIndicate message weight value；ViIndicate the make purchases worth more of message；LiIndicate the length of message content；tiTo disappear
It ceases the time that i is reached, i.e. the time of message i cachings；T is current time.
Wherein, e is used in the calculation formulat-tiInstead of t-tiAs denominator, in order to evade the feelings that denominator is 0
Condition.
In the calculation formula, the make purchases worth more V of messageiBigger, corresponding weighted value is bigger, for example, common message
It can directly transmit, not need to buy after only user being needed to edit, therefore make purchases worth more is relatively low, and for flying screen message and red packet
For message due to needing user's purchase just to can be transmitted, the make purchases worth more of such message is higher；And the message ratio of content-length length
The short message of content is more valuable, for example " main broadcaster is very serious " is more of practical significance than " ".Simultaneously, it is contemplated that the time is for disappearing
The influence of weighted value is ceased, newer message is more important.
S102：Message in caching is ranked up according to weighted value.
In the present embodiment, by obtaining the weighted value of message in caching, it is ranked up according to the size of weighted value, specifically in fact
Now, it can be ranked up according to sequence from high to low, the big message of weighted value comes front, the smaller message row of weighted value
Later, it if the weighted value of message is equal, is ranked up according to the time for entering storage, the rear message into caching comes
It is introduced into before the message of caching.
It is of course also possible to be ranked up according to sequence from low to high, the small message of weighted value comes front, weighted value compared with
Big message comes below, if the weighted value of message is equal, is ranked up according to the time for entering storage, is introduced into caching
Message come after enter caching message before.
It should be noted that in practical application, the rule of sequence can be set according to actual conditions, the present embodiment is herein not
It limits.
S103：When the size of message in caching is more than the Message Payload amount of caching, select to disappear in the message low from weighted value
Breath is deleted, until the size of message in the caching is less than the Message Payload amount of the caching.
Wherein, size of message refers to the size of memory space shared by message in caching.
The Message Payload amount of caching refers to the message capacity that caching can bear, and Message Payload amount can have a variety of settings
Mode in some embodiments can be using the spatial cache of preset ratio as Message Payload amount.For example, with the message of caching
The 70% of the entire spatial cache Message Payload amount for being set as caching is occupied, in this way, for different terminals, Message Payload amount pair
It is identical in the accounting of spatial cache, but the numerical value of particular capacity can be different, which embodies terminal buffers
Storage capacity is judged that energy is more preferable compared to the deletion for judging whether to message by size of message by Message Payload amount
Ground utilizes terminal buffers space, avoids the deletion for excessively deleting message and important messages.
In further embodiments, the specific setting of the Message Payload amount of caching can also be according to user terminal cache size
Difference set, using the spatial cache of different preset ratios as Message Payload amount, spatial cache is bigger, Message Payload amount institute
The accounting for accounting for spatial cache is higher, preferably to utilize terminal buffers space, for example, the spatial cache of user terminal is 2G,
The message then cached occupies the 70% of the entire spatial cache Message Payload amount for being set as caching, shared by the size of message in caching
According to spatial cache be more than above-mentioned setting value when, then delete caching in the lower message of weighted value, with ensure be broadcast live normal operation；
When spatial cache is 4G, then the message cached occupies the 80% of the entire spatial cache Message Payload amount for being set as caching, when slow
When the spatial cache occupied by size of message deposited is more than above-mentioned setting value, then the lower message of weighted value in caching is deleted, with
Ensure live streaming normal operation.
Certainly, can also be according to other according to the settings for carrying out Message Payload amounts in practical application, the present embodiment is herein not
It limits.
When the size of message in caching is more than the Message Payload amount of caching, the lower message of weighted value is deleted in time, that is, is deleted
Except unessential message, prevents certain user from pouring water and the behavior of brush advertisement with this, avoid the influence shown to important messages.
By deleting unessential message, until the size of message in caching is no more than the Message Payload amount in caching.
In practical application, when the size of message in caching is more than the Message Payload amount of caching, if the message in caching is
When being ranked up according to sequence from high to low, then deleted since the last one message of sequence, until the message in caching
Amount then stops deleting less than the Message Payload amount of caching.
If the message in caching is opened from first message of sequence when being ranked up according to sequence from low to high
Begin to delete, until Message Payload amount of the size of message in caching less than caching, then stops deleting.
When the size of message in caching is less than or equal to the Message Payload amount of caching, then the message in normal display caching,
Specifically, carrying out the display of message according to the sequence of weighted value from high to low.
In practical application, when the size of message in caching no more than caching Message Payload amount when, show first weighted value compared with
High message, i.e. important messages, than screen message like flying, red packet message etc., since this kind of message needs user's purchase just to can be transmitted,
Its importance is higher than common message, user can be promoted to buy message of high importance, stimulation consumption with this.
It is understood that if the message in caching is when being ranked up according to sequence from high to low, when in caching
Size of message when being less than or equal to the Message Payload amount of caching, then preferential display comes the message of front.
If the message in caching is when being ranked up according to sequence from low to high, be less than when the size of message in caching or
Equal to caching Message Payload amount when, then preferential display comes subsequent message.
It should be noted that being preferably ranked up according to the sequence of the weighted value of message from high to low.
In some embodiments, the message is text message, when the message that the size of message in caching is more than caching is negative
When carrying capacity, further include：Message groups are formed by every two message in the caching, obtain the similarity of the message groups, institute respectively
It is the similarity in the message groups between two message to state similarity；Then, in the message low from weighted value select message into
Row is deleted, until the Message Payload amount that the size of message in the caching is less than the caching includes：According to the phase of the message groups
Like degree sequence from high to low, in the message groups high from similarity, the message for selecting weight low is deleted, until the caching
In size of message be less than the caching Message Payload amount.
In the present embodiment, when the message that user sends is text message, every two message in caching forms message groups,
The similarity of each message groups is obtained, can be ranked up according to the sequence of similarity from high to low, and higher from similarity
In message groups, the low message of weighted value is deleted.When the weighted value of two message in the message groups is equal, the message groups are selected
The message of the time length of middle caching is deleted.
Wherein, quantity of the similarity for identical characters in two message in the message groups and all characters in two message
Quantity ratio.
In the present embodiment, by the similarity degree of measuring similarity message, the number of words of repeat character (RPT) is more in two message, then
Above-mentioned ratio is bigger, shows that the repetition between message is higher, when ratio is 1, shows that two message are just the same.It is specific to calculate phase
When seemingly spending, it can be calculated using following formula：
Wherein, S is the similarity of two message, and A ∩ B are the quantity of two message repeat character (RPT)s；A ∪ B are to own in two message
The quantity of character, that is, two message total number of characters.
In order to make it easy to understand, assuming that message A is " main broadcaster is very severe ", message B is " main broadcaster is good severe ", then repeat character (RPT) is
The number of words of " main broadcaster is severe ", repeat character (RPT) is 4, and total character is " the very good severity of main broadcaster " in two message, and total number of characters is 6, then compares
Value is 0.67.
In practical application, when size of message exceeds the Message Payload amount in caching in caching, for all texts in caching
Message calculates the similarity between text message two-by-two, obtains highest a pair of of the message of similarity, then deletes wherein weighted value
Low text message.If the weighted value of two message is equal, deletes into message earlier is cached, then repeat above-mentioned behaviour
Make, until the size of message in caching is less than Message Payload amount.
By the filter method of direct broadcasting room message provided by the embodiment, by obtaining the weighted value of message in caching, to slow
Message in depositing is ranked up, and when the size of message in caching is more than the load capacity of caching, it is lower to delete weighted value in order
Message, until the size of message in caching is less than the Message Payload amount of caching.As it can be seen that the filter method provided through this embodiment,
When the size of message in caching is more than the Message Payload amount of caching, the low message of weighted value is deleted, reduction accounts for spatial cache
With the normal display of the smoothness and message of guarantee live streaming picture, optimization is broadcast live performance, promotes user experience.
