Summary of the invention
The technical problem to be solved in the present invention provides the mutual method that shows of a kind of text, can by terminal the text display mode be set under the situation of descriptor disappearance, and makes the terminal use and need organize text message and demonstration according to own hobby.
In order to solve the problems of the technologies described above, the invention provides the mutual method that shows of a kind of text, employing is at text scene description structure that comprises textual description information of decoding end definition, this method comprises following step display: the first step, by the text flow decoder text flow is decoded, thereby obtain plain text information and textual description information respectively; Second step judged whether to extract textual description information from code stream, if comprise new textual description information in the code stream, then screened textual description information and to text scene description structure assignment; In the 3rd step,, organize current text and correctly demonstration on terminal presentation facility by synthetic display module according to the textual description information that comprises in the text scene description structure.
Described text scene description structure is a set of needed all information of text display, comprises the positional information of text display, font size, font type, font color, background information, special efficacy information.
Described text scene description structure provides at least one interface that its content is made amendment.
Described alter mode comprises that the descriptor that carries according to code stream fills, and perhaps makes amendment according to the terminal input.
Defined by the user or the inner self-defining default parameters of use mobile phone of described interface.
Described interface has identical or different priority, and the content of high priority can cover the content of low priority, and the content of low priority can not cover the content of high priority.
In second step,, use default option or prompting user that the content of text scene description structure is provided with if from code stream, do not extract textual description information.
Screening textual description information described in second step is also as follows to the concrete steps of text scene description structure assignment: at first, detect other interface of text scene description structure whether the information input is arranged, and the descriptor of total interface input screened according to priority criteria, remove the content of conflicting with high priority in the low priority; Then, existing information in information after the screening and the text scene description structure is compared and screens, relatively Shai Xuan process is carried out according to priority criteria, if information is identical, then not to text scene description structure assignment, if information is inequality, then the content of high priority covers content corresponding in the low priority.
Compare with prior art, the present invention has following beneficial effect: the present invention can be provided with the text display mode by terminal under the situation of descriptor disappearance, and makes the terminal use and need organize text message and demonstration according to own hobby; The present invention not only can realize the mutual Presentation Function that multimodal text combination shows and realizes text, and is easy to expand and support the application that other are special.

Embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
The present invention is at text scene description structure (Text SceneDescription of decoding end definition, be called for short TSD, its structure is seen Fig. 2), TSD is a set of needed all information of text display, the various information that are used for describing the text display needs are (as the positional information of text appearance, the font color of text, font type, font size, background information, special efficacy information etc.), display module is played up and is located the back by scene description information to the current text that need show and shows in display device.TSD can provide at least one interface that its content is made amendment, can use the descriptor of the correspondence that from code stream, obtains to fill, also can (external interface can comprise any-mode from a plurality of interfaces such as outsides, for example, defined by the user, perhaps can use the inner self-defining default parameters of mobile phone etc.) the textual description information that obtains fills.The priority of each interface can be the same or different, if outstanding user's request can be defined as high priority with the terminal input interface, if the demonstration of some emergency notices then can it is corresponding interface definition be high priority, the descriptor of priority interface definition can cover the defined information of low priority, thereby realizes the mutual function that shows.
Decoding and displaying flow process of the present invention is as shown in Figure 3:
The first step: by the text flow decoder text flow is decoded, thereby obtain plain text information (text) and textual description information (text description) respectively.
Second step: if from code stream, do not extract textual description information, then can use default option or prompting user that the content of text scene description structure is provided with (do not have only aforesaid two kinds of processing methods, can use any alternative processing method); If comprise new textual description information in the code stream, whether have information input, and the descriptor of total interface input is screened according to priority criteria if then detecting other interface of TSD, remove the content of conflicting with high priority in the low priority; Existing information compares and screens among information after will screening then and the TSD, relatively Shai Xuan process is still carried out according to priority criteria, if information is identical then not to the TSD assignment, if it is inequality, then the content of high priority can cover content corresponding in the low priority, otherwise then is false.
Wherein, the priority criteria of interface input screening is: when conflict appears in descriptor (as all font size being defined), the descriptor that priority is high can cover the low descriptor of priority.
The 3rd step:, organize current text and correctly demonstration on terminal presentation facility by synthetic display module according to the textual description information that comprises among the TSD.
