Problems solved by technology

[0005] In the process of realizing the above-mentioned subtitle display, the inventor has found that at least the following problems exist in the prior art: whether a channel contains teletext subtitles and which page the teletext subtitles are contained in is determined by the teletext signal. The transmitter determines that the user cannot know in advance, so it can only determine which page is the page where the teletext subtitle is located after searching each page in the teletext data in turn, and finally display the content carried in the teletext subtitle
This makes the process of displaying teletext subtitles time-consuming and inefficient

Abstract

The embodiment of the invention provides a subtitle display method and device. The method and the device are used for shortening the time consumed in the teletext subtitle display and improving the teletext subtitle displaying efficiency. The method includes the steps of obtaining a teletext subtitle instruction, determining the page number which the teletext subtitle in the current channel belongs to, outputting the page number which the teletext subtitle belongs to, receiving a page number selection instruction, and outputting the teletext subtitle in the page which the selected page number belongs to. Thus, by automatically searching for the page where the teletext subtitle is located, a user can output the subtitle which need to be displayed only by sending the teletext subtitle research instruction and selecting the page number of the page where the found subtitle is located, the operation step for searching for the teletext subtitle is simplified, the time consumed in the teletext subtitle display is finally shortened, and the teletext subtitle display efficiency is improved.

Description

technical field [0001] The invention relates to the field of television, in particular to a subtitle display method and device. Background technique [0002] In the traditional TV data transmission process, TV images are transmitted field by field at a rate of 50 fields (or 60 fields) per second, and there is a gap between two fields that does not transmit image information, which is called "field blanking period ( VBI)". Teletext (Teletext) is to use the blanking period of the TV signal field to transmit additional data information, and the receiving end can watch the transmitted information on the screen by using a dedicated teletext decoder. Therefore, teletext has been popularized and spread widely in many countries and regions in the world with the advantages of low cost and the increase in the number of users without affecting the receiving speed. [0003] Teletext usually uses magazines and pages to organize information, and each magazine can contain up to 100 pages...
