Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the flow chart of the method that the embodiment of the present invention provides;
Fig. 2 is the schematic diagram of the device that the embodiment of the present invention provides.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of protection of the invention.
First it should be noted that, user is when selecting the program liked, all can have a wait from a program to another program, this wait was made up of two time periods: user judge new program whether like thus determine whether to continue required for zapping time+the new program of set top box decodes required for time.That is, user is from after a upper program changes to actual program, first can judge whether to like actual program, or whether actual program is the program oneself wanting to look for, if not, can continue to press zapping key; Then, Set Top Box responds the operation of this zapping, perform each software module is configured, again search rate and to new search to program carry out a series of operations such as decoding process, and demonstrate this next program eventually to user.Visible, these two time periods are consumed respectively by two main bodys (user and Set Top Box) respectively, therefore, there is no need serial completely and carry out.And in prior art, have employed the mode of serial just, therefore waste the time, user is felt, and the response speed of Set Top Box is slow, and then affects the quick of user's zapping and fluency.
Therefore, in embodiments of the present invention, the implementation method of being carried out by above-mentioned two concurrent process is provided, to reaching the object shortening the Set Top Box response time.For reaching this object, see Fig. 1, embodiments provide the method for following response button operation:
S101: while the current button operation of response user, record described current button operation, and add up with the button operation before this user;
S102: when described statistics meets the criteria for prediction preset, dope the operation that user will perform;
S103: backstage responds the operation of described prediction;
S104: if the actual operation made of user is identical with the operation of described prediction, then export backstage to the current response results of the operation of described prediction.
That is, during the Set Top Box response current button of user, this user operation records can be got off, such as, user this be press zapping that key carries out to the next one of actual program, then this information can be recorded, then, do mathematical statistics together with the operation before this user, the result according to this statistics predicts the next one operation that this user will perform.Once after making this prediction, Set Top Box just can immediately in this operation that running background user will perform, when this predicted operation is really performed by user, Set Top Box will respond the instruction of user at once, reduce and even eliminate response time delay, thus the smoothness realizing Set Top Box and user is mutual.
Wherein, due to after the current button of Set Top Box response user, just enter the time period that user judges whether to like actual program, meanwhile, Set Top Box just can perform the operation that above-mentioned statistics, prediction and backstage respond.This backstage response process can comprise each software module is configured, again search rate and to new search to program carry out a series of operations such as decoding process.Visible, in embodiments of the present invention, the response process of Set Top Box is advanceed to user and judge whether to carry out in the time period of liking current results, therefore, achieve the parallel processing that user judges to respond with Set Top Box.
It should be noted that, the time performed needed for operation response due to Set Top Box is relatively fixing, such as, may be about 2 seconds usually; And user judges whether that the time needed for actual program of liking may vary with each individual, the time needed for even each judgement all may be different.But, as long as the time that user judges is greater than the time of Set Top Box execution needed for operation response, when just can ensure that the operation reality predicted is performed by user, Set Top Box has completed the operation responses such as configuration, search, decoding, is directly shown by corresponding program.Certainly, even if the time that user judges is less than the time of Set Top Box execution needed for operation response, when also can be performed by user in the operation reality predicted, the operation response basis that backstage has been carried out proceeds, also relatively can shorten the response time of user awareness.As, when the operation reality of prediction is performed by user, the operation response on backstage has just completed the step of frequency search, not yet to new search to program decode, then the response time of user awareness just only has the time of decoding needed for new program, in terms of existing technologies, user awareness to response time still shorten.
It should be noted that in addition, the specific implementation of backstage response and foregrounding there is no difference in essence, just after completing decoding, if user not yet performs corresponding operation, decoded image is not then needed to show, after user performs corresponding operation, then demonstrate corresponding image.In addition, because TV programme plays in real time, therefore, decoded out but the image do not shown does not need to preserve before user performs corresponding operation, when user performs operation, the directly current decoding of display image out.
From the above, as long as the next one operation that user will perform can be doped exactly, the Set Top Box response time of user awareness just effectively can be shortened.Therefore, how to predict that the next one operation that user will carry out is more crucial problem.In embodiments of the present invention, have employed the Forecasting Methodology that mathematical statistics adds criterion.
Consider following scene: be sitting in the user before television set, when selecting the TV programme oneself liked, normally according to a fixing direction constantly zapping, until the program finding oneself to like, the operation rule of this process to Set Top Box is apparent, therefore, as long as make Set Top Box this rule " can be found ", just may make and predicting exactly.
In order to reach this object, some criteria for prediction can be pre-established, can comprise in this criteria for prediction predict the outcome (which kind of operation) of Rule of judgment and correspondence; Carry out after mathematical statistics obtains statistics, can judging whether this statistics meets the condition in certain criteria for prediction, if met, then using the predicting the outcome next one operation doped as this in this criteria for prediction to user operation.
Such as, this criteria for prediction can be: when user presses key (or upper key) more than three times continuously, can predict that the next one operation of user is the next one (or the upper one) program that zapping arrives actual program.Once complete prediction that Here it is.Certainly, user also can carry out zapping operation by the mode of pressing numerical key, therefore this criteria for prediction can also be: the digital continuous time of the numerical key pressed for three times when user is continuous, when can predict that the next one of user operates, zapping is to the next program of actual program, the serial number of the TV station that this next program is corresponding is that current number sequence number adds one or subtract one, etc.
Like this, when Set Top Box obtain one predict the outcome after, Set Top Box just can carry out the work responding this corresponding operation that predicts the outcome in advance, the operate in backstage corresponding by this prediction realizes, when user has really made operation according to this prediction, Set Top Box just can give to respond fast, thus realizes smooth man-machine interaction.It should be noted that, while current response fast, the time that Set Top Box utilizes user to judge (judges whether this program oneself is liked, or whether be the program etc. oneself wanting to search), start prediction next time and achieved this new predicted operation on backstage, for preparation is made in quick response next time.
Certainly, if really accomplish the response time that shortening user awareness arrives, then need to predict the outcome accurately.Namely only obtain and predict the outcome, and the operation of the next one of user really predicts the outcome identical with this, just really can shorten the response time that user awareness arrives.Otherwise, if the next one operation of user with predict the outcome different, then idle work has just been done in the consistency operation before, and Set Top Box still needs the next one again responding this user to operate.
Usually the real realization of prediction is called hit, the number of times of hit is then called hit rate with the ratio of the number of times of prediction.Obviously, hit rate is higher, then more can reach the object of response fast on the whole.And according to the Forecasting Methodology that the embodiment of the present invention provides, this hit rate depends on criteria for prediction and statistics.Wherein, criteria for prediction can adopt the mode of manpower intervention to adjust, and owing to not relating to technical problem, therefore repeats no more here; Choosing of statistics, can be optimized by technological means.
In actual applications, concrete optimal way can have multiple, such as, can consider following situation: after user may select a program, after a period of time, can may again select other program; And the channel switching method used in twice selection course may be different, there is different regularity.Such as, when first time is selected, user adopts the mode of pressing key continuously, and when second time is selected, user adopts the mode pressing key continuously.Obviously, for the prediction of second time selection course, the data recorded in selection course for the first time do not have reference value, even may affect the hit rate of this time prediction.
Therefore, in order to improve the hit rate of prediction, the data that the embodiment of the present invention can be no more than preset threshold value the selection operation time interval are added up.That is, if the time interval between twice operation has exceeded this preset threshold value, then thought that user is carrying out the zapping operation of same bout, therefore, the data of front once-through operation can deleted, avoid causing interference to this prediction.
In a word, by the method that the embodiment of the present invention provides, top box of digital machine is made to be provided with intelligentized characteristic, the order that top box of digital machine received from user there can, as the data source of mathematical analysis statistics, can make to produce tacit agreement between user and top box of digital machine to the appropriate process of this statistics.In other words, the method that the embodiment of the present invention provides, achieves the rational man-machine division of labor, harmonious running better, makes the process of man-machine interaction, as far as possible parallel processing, is equivalent to the thinking of people that independently thread or process are dissolved in the middle of top box of digital machine software as one.In essence, the embodiment of the present invention uses CPU more and more efficiently, made full use of by more and more cheap memory source, exchange the time for space, thus give top box of digital machine user more smooth numeral experience.
