Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
A kind of caching method of multifrequency track data is provided in an embodiment disclosed by the invention, to cache multichannel number
Corresponding video is can play according to so as to improving data loading efficiency, realizing to wait without user after zapping.As shown in figure 1, this
A kind of caching method of multifrequency track data includes step S10-S30 in inventive embodiments：
Step S10, the Action Events corresponding to user's viewing television channel in preset duration are recorded, obtain the operation thing
Historical data corresponding to part.
In the embodiment of the present invention, the foundation of played data is corresponding to multiple channels of buffered television machine：In certain time length,
User watches the historical record corresponding to different television channels based on the television set；It is also understood that gone through by recording user
Above and below corresponding to the television channel that history viewing behavior, several television channels that acquisition user often sees, or acquisition are often seen
Associated channel, such as CCTV1 and CCTV2, closed on corresponding to television set on TV band, be so easy to user by the upper of channel
The television channel that lower key etc. can conveniently switch.
In one embodiment, as shown in Fig. 2 the step S10 may be embodied as step S101-S102：
Step S101, in preset duration, monitoring user watches program viewing event and the channel that television channel is triggered
Handover event；
In preset duration within such as one month or two weeks, the program that monitoring user watches corresponding to television channel is seen
Event and channel switching event are seen, such as, which channel user have viewed, and generally be switched between which channel
Deng.
Step S102, the program play messages corresponding to the program viewing event, and the channel switch thing are recorded
Channel switching information corresponding to part, obtain historical data corresponding to the program viewing event and the channel switching event.
Corresponding to the monitored user of record while program viewing event, obtain corresponding to above-mentioned program viewing event
Programme information, such as, the programme information is advertisement or movie and television play etc.；Meanwhile record corresponding to above-mentioned channel switching event
Channel switching information, such as, which channel what user often watched is, is generally switched between which channel,
Each channel have viewed respectively how long etc..By recording above- mentioned information, the program viewing event and frequency of user's triggering are obtained
Historical data corresponding to road handover event.
Step S20, the historical data is parsed, the viewing for obtaining television channel in the historical data records, and according to
The viewing record, formulates data buffer storage rule.
The above-mentioned historical data of new record is solved, according to analysis result, it is corresponding that television channel is obtained from above-mentioned historical data
Viewing record, so as to according to viewing record, formulate data buffer storage rule.Such as corresponding to currently playing programme information
When being advertisement, start channel played data corresponding to other channels that cache user often switches.
In one embodiment, as shown in figure 3, the step S20 may be embodied as step S201-S203：
Step S201, according to default resolution rules, the historical data is parsed；
Above-mentioned historical data is parsed according to the resolution rules carried in television set, or, dispatched from the factory according to television set
During setting, resolution rules that technical staff redefines parse above-mentioned historical data.
Step S202, according to analysis result, obtain program corresponding to the historical data and play content, program playing duration
And channel switching information；
Step S203, content, program playing duration and channel switching information are played according to the program, formulates data and delay
Deposit rule.
According to analysis result, obtain the program corresponding to above-mentioned historical data and play content, for example, play be advertisement also
It is TV play or entertainment, while obtains program playing duration and channel switching information, such as the frequency from A channel switch to B
Road etc..The above-mentioned program obtained according to parsing plays content, program playing duration and channel switching information, intelligently formulates corresponding
Data buffer storage rule.For example when A channels play advertisement, automatic cache regards corresponding to the currently playing programme information of B channels
Frequency evidence.
When step S30, detecting that the currently playing programme content of television set meets data buffer storage rule, download and cache institute
State channel predetermined corresponding channel data in viewing record.
When detect the currently playing programme content of television set meet it is above-mentioned specify data buffer storage rule when, directly download
Channel predetermined corresponding channel data in viewing record corresponding to user, and the channel data of download is cached, it is easy to use
During the zapping of family, the video corresponding to the video data of caching is directly played.
In one embodiment, as shown in figure 4, the step S30 may be embodied as step S301-S303：
Step S301, the current program content that television set is playing is obtained；
In the embodiment of the present invention, TV obtains the current program content being currently played in real time, or according to default week
Such as 10 milliseconds or 50 milliseconds of phase, periodically obtain the current program content played.
Step S302, identify that the current program content plays content phase with the program in the data buffer storage rule
Timing, download channel predetermined corresponding channel data in the viewing record；
Step S303, the channel data downloaded is cached.
Identify that the current program content played plays content with the program in the above-mentioned data buffer storage rule specified
When matching, such as when to detect currently playing content be advertisement, then download it is channel predetermined in viewing record corresponding to channel
Data, and cache the above-mentioned channel data downloaded.
On the basis of the method for processing video frequency that above-described embodiment is provided, when television reception to user wants zapping, directly
Current channel is switched to the channel of user's replacing, and directly plays program corresponding to the channel.As shown in figure 5, the present invention is real
Applying a caching method for multifrequency track data also includes：
Step S40, the channel switching instruction of user's triggering is received, channel switch Action Events is performed, plays the channel
The channel data cached corresponding to switching command.
During the channel switching instruction that television reception triggers to user, channel switch Action Events are performed, current channel A is cut
Channel B corresponding to above-mentioned switching command is shifted to, while the channel data for calling TV corresponding to channel B to cache；Utilize calling
The above-mentioned channel data cached, directly play program corresponding to channel B, user loads B pairs of channel without waiting for TV
The channel data answered, corresponding TV programme can be watched immediately, improve user's viewing experience.
The caching method of above multifrequency track data, by recording the behaviour in preset duration corresponding to user's viewing television channel
Make event, obtain historical data corresponding to the Action Events；The historical data is parsed, obtains TV in the historical data
The viewing record of channel, and recorded according to the viewing, formulate data buffer storage rule；Detect the currently playing program of television set
When content meets data buffer storage rule, download and cache channel predetermined corresponding channel data in the viewing record；With slow
Multifrequency track data is deposited so as to improve the beneficial effect of data loading efficiency, realizes and waits i.e. playable pair without user after zapping
Answer the purpose of video；Improve Consumer's Experience.
