Problems solved by technology

[0006] Since the design rule of the Teletext function is to use one byte to represent the character content, the current Teletext function only supports languages ​​that use a single byte to encode characters, such as Latin languages ​​(such as English, French, German, Italian, Spanish), Cyrillic (Serbia, Croatia, Bulgaria, Russia), Greek, Arabic, Hebrew, but languages ​​that require multiple byte-encoded characters, such as Chinese, Japanese, Korean, Mongolian, Persian, etc. are not supported , therefore, the use of the current native Teletext information transmission function cannot meet the needs of multilingual transmission

Embodiment Construction

[0055] As stated in the background technology of this application, in the existing Teletext functional scenario, because it can only express the limitation of character content through a single byte, it can only support the transmission of some languages, and for Chinese, Japanese, Korean , Mongolia, Persian and other languages ​​cannot be transmitted with the help of the Teletext function, which greatly limits the scope of application of the Teletext function. For users and regions using the above languages, the content restrictions transmitted by the Teletext function also bring inconvenience to users .

[0056] This is because the design rule of the Teletext function is to use one byte, that is, the commonly used ASCII code to represent the character content. For more complex languages ​​such as Chinese, it is necessary to use two consecutive extended areas of the extended ASCII code to represent a Chinese character. Therefore, when the original Teletext function is used to...

Abstract

The embodiment of the present application discloses a method and device for transmitting Teletext information. The method adds a Unicode code to the packet header information of the transmitted data packet set when the to-be-transmitted data packet that needs to be transmitted for Teletext information carries an extended identifier. mark, and add the Unicode code content length mark and the Unicode code content information of the corresponding length in each content data packet, thus, in the transmission process of the Teletext information, the transmission of the Unicode code content is realized, and the Teletext function is extended to multilingual graphics The supported range of text information enriches the types of content transmitted through the Teletext function, improves user experience, and meets the diverse needs of transmission content in the Teletext function scenario.

Description

technical field [0001] This application relates to the field of graphic display, in particular to a method and device for transmitting Teletext information. Background technique [0002] The Teletext function, that is, the graphic function, inserts some information (such as weather forecast, lottery tickets, football matches, and team information) into the field blanking line of VBI (Virtual Brand Integration) in the era of analog TV. It is transmitted to the TV, and the TV then decodes and displays the information on the TV screen, thereby providing users with additional information. [0003] In the digital TV era, the graphic and text functions are preserved, and the graphic and text information is transmitted to the digital TV through TS Packet (Transport Stream Packet, Transport Stream Packet), so that it is compatible with the original functions. [0004] The Teletext function is designed to transmit display control information, character content, such as font color, f...
