For making the purpose of the present invention, technical scheme and advantage clearer, develop simultaneously embodiment referring to the drawings, right
The present invention is described in further detail.
From background technology it can be seen that when user wants Switch Video channel, no matter use in background technology is any
Method, is required for user's multi-pass operation and just can complete, and this brings complexity and the degree of difficulty of operation for user.In order to overcome this
Individual problem, embodiment of the present invention real-time storage user watches the historical information of video channel, switches the video of client user
During channel, watch the historical information of video channel according to described user, be calculated user and watch choosing of each video channel
After probability, the probability of choosing according to being calculated is switched to wherein on a video channel at random.In this manner it is possible to according to user's request
It is automatically performed the switching of corresponding video channel.
The method flow diagram of the Switch Video channel that Fig. 1 provides for the embodiment of the present invention, it concretely comprises the following steps:
Step 101, client carry out user and watch the historical information real-time statistics of video channel；
Step 102, when client wants Switch Video channel, watch the historical information of video channel according to described user,
What the user being calculated in current slot watched each video channel chooses probability；
Step 103, according to calculated choose probability the video channel of client is switched at random wherein one video frequency
On road.
In step 101 in the method, user watches the historical information real-time statistics of video channel and is:
In set measurement period, counting user watches the viewing duration information of each video channel.
Described measurement period can be to be divided into several time slices, with each time slice for one by one day 24 hours
Individual measurement period.
In statistic processes, first client obtains current date and time, to determine the statistics residing for current time
In the cycle, then, the user of same measurement period and the same measurement period on upper one week date that client transfers a date sees
See the historical information of video channel, carry out cumulative statistics: if the historical information of upper a week does not exists, the institute on an above date
On the basis of stating the historical information that user watches video channel, add up；Otherwise the described user of above a week watches video frequency
On the basis of the historical information in road, add up.It is measurement period value that each user watches time of video channel upper limit that adds up.
Before statistics, the method also includes:
Client receives the viewing video channel request of the not counting user setting that user sends, and the most counting user does not sets
Viewing video channel historical information.
In the step 102 of the method, the method also includes: it is corresponding that described user watches the historical information of video channel
User account, the historical information that the user of corresponding user account watches video channel is sent to server end by client；
When client wants Switch Video channel, watch video channel from the user of server calls correspondence user account
Historical information.
In the method, the method can also include:
Remote controller in client arranges the button of direct viewing TV, when client receives the sight that described button sends
After seeing request, the video channel of client is switched on a video channel at random.Adopt is in view of family old man in this way
Only watch TV programme by client with child's most of the time, seldom use other senior application.And client provides at present
The multiple setting of multiple resources, it is also possible to open multiple application.For old man and the child of family, even some youngsters use all
Too complex, needs to arrange the button of a direct viewing TV on the remote controller of client, it is also possible to be one promptly by
Key, a key can see TV.The embodiment of the present invention provides this function, and no matter which kind of state TV is currently at, if user
Clicking on the button of direct viewing TV, will send high priority other viewing request to client, client is the most automatically
It is switched to television mode, and uses the method intelligent selection suitable video frequency of Switch Video channel that the embodiment of the present invention provides
Road is play.
In the method, described when client wants Switch Video channel be client open time, namely work as client
The suitable video channel of method intelligent selection just using the Switch Video channel of the embodiment of the present invention offer during unlatching is play.
In step 103 in the method, the video channel of client is switched by probability of choosing according to being calculated at random
Time on a wherein video channel, video channel choose probability the highest, the probability of random switching is the biggest, further,
When switching at random, can not limit choosing video channel that probability the is the highest video channel as random switching.
In the step 102 of the method, the probability calculation of choosing of described video channel is:
Arranging client has N number of video channel, two video channels of the most only A and B to have viewing record, A video frequency
Road have viewed a second, and B video channel have viewed the b second.The probability of choosing of so A video channel is P (A)=a/ (N-2+a+b), and B regards
The probability of choosing of frequency domain channel is P (B)=b/ (N-2+a+b).It is to say, video channel choose probability=video channel history
Cumulative viewing time value/(video of the video channel number of client total channel number-had viewing record+had viewing record
Total viewing time value of channel).
In the step 102 of this method, described in the user that is calculated in current slot watch each video channel
The probability is chosen to be:
Calculate current time and drop in which measurement period, then call the user in described measurement period and watch each
The historical information of video channel, calculate that user watches each video channel chooses probability.
In the present invention, not having described historical information when client initialization, the viewing time of all video channels is write from memory
Thinking 1, such as, have 40 video channels, the probability of choosing of the most each video channel is 1/40；User is at continuous Switch Video frequency
During road, with set measurement period span as boundary, after the video channel that all selected but user abandons watching is no longer participate in
Continuous randomly chooses, and so, the video channel avoiding big probability always occurs, but the situation that user is not desired to viewing is sent out
Raw.
In the present invention, client arranges Backward Function, in order to user can return back to the channel chosen before.This
The scene of application is user by quickly carrying out the switching of video channel by the remote controller of client, and imprudence misses to be wanted to see
This function can be used during video channel.
In the present invention, the video always real-time change play due to each video channel of client, if only had
The several rules arranged determine that video channel switches at random, may result in some video channels chosen at random and have adjusted
After programme content, user does not likes to see, but it chooses probability the highest due to calculate, still can be directly switch to this and regard
On frequency domain channel, cause the problem that user experience is the highest, at this moment, it is necessary to choose probability to set this type of video channel
The punishment of fixed punishment rule.
Concrete process is:
When on certain video channel of client, residence time is less than set threshold value to user, then client is recognized
Do not like this channel for user, therefore choose probability to punish this video channel.Now inquire about this video channel
Choose probability, if this video channel has the historical information of viewing, cut down its statistical value setting quantity, after number wheel iteration
This video channel drops to less chooses probability.This process is not only applicable to the feelings that client only one of which user uses
Condition, applies also for the situation that client has multiple user to use.Such as family has three people, likes respectively to see different video frequencies
Road, then the probability of choosing being suitable for these rear three video channels of rule is all of a relatively high, then at Switch Video channel
Time client just can preferably at most choose the video channel of probability to switch over for different user accounts.
