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 application discloses a Teletext information transmission method and apparatus. The method includes the following steps: when to-be-transmitted data packets that need Teletext information transmission carries extended identifiers, adding Unicode identifiers to packet header information of a transmitted data packet set, and adding Unicode content length identifiers and Unicode content information with a corresponding length to content data packets. Therefore, during Teletext information transmission, Unicode contents are transmitted, the range of multilingual picture and text information supported by a Teletext function is increased, content types of transmission through the Teletext function are increased, the user experience is improved, and demands for diversified transmission contents in a Teletext function scene are met.

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...
