Embodiment 1

[0030] figure 2 The implementation process of the method for obtaining the output graphic language of the code stream provided by the first embodiment of the present invention is shown, and the details are as follows:

[0031] In step S201, all current graphic languages ​​in the current code stream of the current program are obtained.

[0032] Specifically, when a user is watching a certain program, and usually, a certain program often includes multiple graphic languages, such as Chinese, English, French, etc., it involves choosing which graphic language to use as the preferred language. The output language for this program. Through this step S201, the code stream at a certain moment of the current program or all the current graphic languages ​​in the current code stream can be obtained from the set-top box, for example, according to the order in which the current graphic languages ​​appear in the current code stream, the acquired All current graphic languages ​​include Chi...

Abstract

The invention is suitable for the technical field of a set top box and provides a method and a device for acquiring an output image-text language of a bit stream and a set top box. The method comprises the following steps of: acquiring all current image-text languages in a current bit stream in a current program; according to a preset corresponding relation table of the image-text languages and weights, acquiring the weight corresponding to each current image-text language; and setting the current image-text language corresponding to the maximum weight into the output image-text language of the current bit stream. According to the method and device provided by the invention, by presetting the corresponding relation table of the image-text languages and the weights, the weights of all the current image-text languages in the current bit stream can be acquired so as to easily acquire the current image-text language corresponding to the maximum weight, and therefore, the time and the space which are required by the operation are reduced, the image-text language required by a user is more rapidly acquired, the response speed and efficiency are also improved and the like.

Description

technical field [0001] The invention belongs to the technical field of set-top boxes, and in particular relates to a method, a device and a set-top box for obtaining an output graphic language of a code stream. Background technique [0002] Set-top boxes are playing more and more roles in people's lives. The graphic function can display program subtitles for users, and users can obtain the information they need more conveniently and quickly. At the same time, it also provides some help for users with visual or hearing impairments, so that they can obtain some TV information more effectively, so as to make up for the information loss caused by hearing and visual impairments. As we all know, when there are multiple graphic languages ​​in a program, it involves the issue of which graphic language is preferred. According to the user's needs, the set-top box software can often store the graphic language selected by the user, set the default graphic language, and so on. Usually,...
