Be illustrated in figure 1 as so that picture and text are divided into following three kinds (actual conditions maybe be more) according to priority, the user selects a certain picture and text language A in the code stream through the interface of STB; Certain acquiescence picture and text language B that the application software of STB is provided with through the user; The common picture and text language of in the code stream other C is an example, utilizes prior art to obtain the method flow diagram of the output picture and text language of code stream, is described below:
In step S101, the general using STB obtains all the current picture and text language in the current code stream of current program data.
In step S102, whether each current picture and text language of cycle detection meets the situation of A, be, execution in step S103 then, the current picture and text language that meets the A situation is set to limit priority, not, then continues execution in step S104.
In step S104, whether each current picture and text language of cycle detection meets the situation of B, be, execution in step S105 then, the current picture and text language that meets the B situation is set to limit priority, not, then continues execution in step S106.
In step S106, whether each current picture and text language of cycle detection meets the situation of C, is; Execution in step S107 then; The current picture and text language that meets the C situation is set to limit priority, not, then continues execution in step S108; It is limit priority that empty output language is set, and does not also promptly export any language.
Step S109, the current picture and text language that output priority is the highest.
Finally more just can draw the highest a kind of current picture and text language of current priority through the recycle ratio of permanent order repeatedly; And then the highest current picture and text language of output priority; If the current picture and text language of next segment encode stream changes, then repeating step S101 is to step S109.Yet this method need be passed through multiple recycle ratio, again the picture and text language is sorted and compares; Make that the selection course of picture and text language of limit priority is relatively redundant; And the more time and space resource of consumption system, efficient is lower, influences the response speed of STB.

Below in conjunction with specific embodiment concrete realization of the present invention is described in detail:
Embodiment one:
Fig. 2 shows the realization flow of the method for the output picture and text language that obtains code stream that first embodiment of the invention provides, and details are as follows:
In step S201, obtain all the current picture and text language in the current code stream of current program.
Particularly, when the user when watching a certain program, and generally, a certain program has often comprised multiple picture and text language, such as, Chinese, English, French etc. then relate to the output language of any picture and text language of preferential selection as this program.Can from STB, obtain through this step S201 current program a certain moment code stream or claim all the current picture and text language in the current code stream; Such as the sequencing that in current code stream, occurs according to current picture and text language, all current picture and text language of this that obtains comprise Chinese, English, three kinds of current picture and text language of French successively.
In step S202,, obtain and the corresponding weight of each current picture and text language according to the preset picture and text language and the mapping table of weight.
Wherein, comprise the picture and text language of the multiple appointment of setting in advance in the mapping table of this preset picture and text language and weight, and with the picture and text language of this multiple appointment in each picture and text language weight one to one.In addition; The mapping table of this picture and text language and weight also comprises other picture and text language except that the picture and text language of above-mentioned multiple appointment that are provided with in advance; The pairing weight of these other picture and text language is identical, and less than the corresponding weight of any one picture and text language in the picture and text language of above-mentioned multiple appointment.
Particularly, according to user's needs, set-top box software usually can be stored picture and text language that the user selects, picture and text language of acquiescence or the like is set; Such as the mapping table that can set up picture and text language and weight in advance, stored the multiple picture and text language that the user possibly need usefulness in this mapping table, also comprise the weight corresponding with each picture and text language; The picture and text language of selecting such as the user is the Chinese of appointment, and this Chinese weight can be set is 10000, and the English that first default language is appointment is set; The weight that this English is corresponding is 1000; The French that second default language is appointment is set, and the weight that this French is corresponding is 100, and the Japanese that the 3rd default language is appointment is set; The weight that this Japanese is corresponding is 10 etc., also can be provided with except that Chinese, English, French, the weight of other picture and text language the Japanese and be 0 etc.
In embodiments of the present invention, this step S202 is specially:
Judge whether arbitrary current picture and text language in these all current picture and text language belongs to the picture and text language of a kind of appointment in the mapping table of this preset picture and text language and weight;
When judged result when being, the corresponding weight of this arbitrary current picture and text language is set to the corresponding weight of picture and text language of this a kind of appointment;
When judged result for not the time, the weight of this arbitrary current picture and text language is set to the corresponding weight of any one other picture and text language;
Repeat above-mentioned steps, until obtaining and the corresponding weight of each current picture and text language.
After this step S202, the method for this code stream that obtains output picture and text language also comprises:
Set up and store the language and the weight relationship table of this current code stream, this language comprises this each current picture and text language and corresponding weight of each current picture and text language with this with the weight relationship table.
In concrete implementation process; All current picture and text language can comprise that Chinese, English, three kinds of current picture and text language of French are example with this; Judge in regular turn whether exist in the mapping table of picture and text language that this is preset and weight should Chinese, English, French, the respective weights of then obtaining is respectively 10000,1000,100.If this current picture and text language is Russian; And the mapping table of picture and text language that should be preset and weight is not stored as the picture and text language of the appointment of Russian; Then the weight of this Russian is set in this mapping table the corresponding weight of other picture and text language, and the correspondence weight that can know this Russian of tabling look-up is 0.
Further; After obtaining the weight corresponding with each current picture and text language; Can set up the language and the weight relationship table of this current code stream, this language comprise this each current picture and text language with the weight relationship table and with this corresponding weight of each current picture and text language, and this language and weight relationship table be stored in the region of memory of STB temporarily; After this STB was closed, language in the region of memory and weight relationship table just can be deleted.
In step S203, pairing current picture and text language was set to the output picture and text language of this current code stream when weight was maximum.
Particularly, when pairing current picture and text language was multiple when this weight is maximum, pairing current picture and text language perhaps was this current picture and text language that in this current code stream, occurs at first for any one this current picture and text language when this weight maximum was set.
Since in the picture and text language that should be preset and the mapping table of weight except that the picture and text language of appointment; The weight of other picture and text language is identical; Pairing current picture and text language was multiple when the weight that then might get access to was maximum; Then this moment the user can be provided with as required this weight when maximum pairing current picture and text language be any one this current picture and text language, also can be this current picture and text language of appearance etc. at first in this current code stream.And the weight of the Chinese in current picture and text language is set is 10000, and English weight is 1000, after the weight of French is 100, can find out that the weight of Chinese is maximum, and then this Chinese is set to the output picture and text language of this current code stream.
In the practical implementation process; Can obtain the method for the output picture and text language of code stream through this for the different code streams of any program; Obtain the weight maximum picture and text language that priority is the highest in other words; The output picture and text language of current code stream can meet the user and watch needs, improves user's experience.
