Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Disclosed by the invention one caching method that embodiments provides a kind of multichannel data, improves data loading efficiency in order to buffer memory multichannel data, waits for can play corresponding video after realizing zapping without the need to user.As shown in Figure 1, in the embodiment of the present invention, a kind of caching method of multichannel data comprises step S10-S30:
In step S10, record preset duration, user watches the Action Events corresponding to television channel, obtains the historical data that described Action Events is corresponding.
In the embodiment of the present invention, the played data that multiple channels of buffered television machine are corresponding according to being: in certain time length, user watches the historical record corresponding to different television channel based on this television set; Also can be understood as, by recording user history viewing behavior, obtain several television channels that user often sees, or obtain the associated channel up and down corresponding to television channel often seen, such as CCTV1 and CCTV2, the TV band that television set is corresponding is closed on, is convenient to the television channel that key up and down etc. that user presses channel can conveniently switch like this.
In one embodiment, as shown in Figure 2, described step S10 may be embodied as step S101-S102:
Step S101, in preset duration, the supervisory user viewing program viewing event that triggers of television channel and channel switching event;
In preset duration within such as one month or two weeks, the supervisory user program viewing event of viewing corresponding to television channel and channel switching event, such as, which channel user have viewed, and usually switches etc. between which channel.
Step S102, record program play messages corresponding to described program viewing event and the channel switching information that described channel switching event is corresponding, obtain described program viewing event and historical data corresponding to described channel switching event.
While recording program viewing event corresponding to the user that monitors, obtain the programme information corresponding to above-mentioned program viewing event, such as, this programme information is advertisement or movie and television play etc.; How long etc. meanwhile, record the channel switching information corresponding to above-mentioned channel switching event, such as, which channel what user often watched is, usually switches between which channel, have viewed respectively at each channel.By recording above-mentioned information, obtain the program viewing event of user's triggering and the historical data corresponding to channel switching event.
Step S20, resolve described historical data, obtain the viewing record of television channel in described historical data, and according to described viewing record, formulate data buffer storage rule.
Separate the above-mentioned historical data of new record, according to analysis result, from above-mentioned historical data, obtain the viewing record that television channel is corresponding, thus according to viewing record, formulate data buffer storage rule.Such as, the programme information of current broadcasting corresponding be advertisement time, start the channel played data that other channels of often switching of cache user are corresponding.
In one embodiment, as shown in Figure 3, described step S20 may be embodied as step S201-S203:

Step S202, according to analysis result, obtain program play content corresponding to described historical data, program playing duration and channel switching information;
Step S203, according to described program play content, program playing duration and channel switching information, formulate data buffer storage rule.
According to analysis result, obtain the program play content corresponding to above-mentioned historical data, what such as play is advertisement or TV play or entertainment, obtains program playing duration and channel switching information, such as from A channel switch to B channel etc. simultaneously.According to resolving the above-mentioned program play content, program playing duration and the channel switching information that obtain, formulate corresponding data buffer storage rule intelligently.Such as, when A channel broadcast advertisement, the video data that the programme information of the current broadcasting of automatic buffer memory B channel is corresponding.
Step S30, when detecting that the programme content of the current broadcasting of television set meets data buffer storage rule, to download and the channel data of channel predetermined correspondence in viewing record described in buffer memory.
When detecting that the programme content of the current broadcasting of television set meets above-mentioned data buffer storage rule of specifying, the channel data of channel predetermined correspondence in the viewing record that direct download user is corresponding, and the channel data of download is carried out buffer memory, when being convenient to user's zapping, play-over the video corresponding to video data of buffer memory.
In one embodiment, as shown in Figure 4, described step S30 may be embodied as step S301-S303:
The current program content that step S301, acquisition television set are being play;
In the embodiment of the present invention, the current current program content play of TV Real-time Obtaining, or according to predetermined period such as 10 milliseconds or 50 milliseconds, the current program content that regular acquisition is being play.
When step S302, the program play content identified in described current program content and described data buffer storage rule match, download the channel data of channel predetermined correspondence in described viewing record;
The described channel data that step S303, buffer memory have been downloaded.
When the program play content identified in the current program content and above-mentioned data buffer storage rule of specifying play matches, when the content current broadcasting such as being detected is advertisement, then download the channel data of channel predetermined correspondence in viewing record, and the above-mentioned channel data downloaded of buffer memory.
On the basis of the method for processing video frequency provided at above-described embodiment, when television reception wants zapping to user, directly current channel is switched to the channel that user changes, and play-over program corresponding to this channel.As shown in Figure 5, the caching method of embodiment of the present invention multichannel data also comprises:
The channel switching instruction that step S40, reception user trigger, performs channel switch Action Events, plays the described channel data of buffer memory corresponding to described channel switching instruction.
During the channel switching instruction that television reception triggers to user, perform channel switch Action Events, current channel A is switched to the channel B that above-mentioned switching command is corresponding, call the channel data of TV corresponding to channel B buffer memory simultaneously; Utilize the channel data of the above-mentioned buffer memory called, play-over the program that this channel B is corresponding, user, without the need to waiting for that TV loads channel data corresponding to channel B, just can watch corresponding TV programme immediately, improve user's viewing experience.
The caching method of above multichannel data, watches the Action Events corresponding to television channel by user in record preset duration, obtains the historical data that described Action Events is corresponding; Resolve described historical data, obtain the viewing record of television channel in described historical data, and according to described viewing record, formulate data buffer storage rule; When detecting that the programme content of the current broadcasting of television set meets data buffer storage rule, download the channel data also watching channel predetermined correspondence in record described in buffer memory; There are buffer memory multichannel data thus the beneficial effect of raising data loading efficiency, after achieving zapping, wait for the object can playing corresponding video without the need to user; Improve Consumer's Experience.
