The Tibetan language has a history of nearly 1,300 years, and a vast number of classics have been written in Tibetan. In terms of quantity, it is second only to Chinese classics in my country. These classics record the rich and colorful Tibetan culture that has attracted worldwide attention, and are an important part of the Chinese culture. Tibetans are the main ethnic group in the Tibet Autonomous Region, accounting for 93% of the region's population. In addition to the Tibet Autonomous Region, Tibetans are also distributed in Qinghai, Sichuan, Gansu and Yunnan provinces, with a population of nearly 5 million, who mainly use Tibetan. In addition, there are still a large number of people in neighboring countries who use Tibetan.

With the rapid growth of my country's economy and the rapid development of the communication industry, the application of handheld electronic terminals/mobile phones has become more and more popular, and has increasingly become an indispensable consumer product in people's daily life, and Tibetan areas are no exception. Since there are no Tibetan cultural handheld electronic terminals/mobile phones at home and abroad, the further popularization of these applications in Tibetan areas has been restricted to a large extent, and the promotion of related value-added services by telecom operators has also been affected.

As far as the method of Tibetan input is concerned, as in CN 1403901 A of Sichuan Fire Fox Electronics Co., Ltd., a kind of Tibetan shape input method and keyboard are disclosed, wherein a kind of Tibetan shape input method supporting Windows system is provided, the method It can also support English and Chinese input systems. According to the spatial structure of Tibetan characters, the components are space-divided, each combination of characters is given different keyboard key definitions, and the order of character formation is established, and the established order is followed when inputting Input the mapping keys of the components in turn, and press the confirmation key after completing the input of all the mapping keys of a character to obtain the corresponding Tibetan text. But this input method is not suitable for Tibetan input on the small keyboard.

【Detailed ways】

The present invention will be described in detail below in conjunction with accompanying drawing by embodiment:

A Tibetan cultural handheld electronic terminal/mobile phone should have a complete function of sending and receiving Tibetan text messages. It has a complete and friendly interface in all Tibetan languages; it has an easy-to-learn and easy-to-use Tibetan input method; and it has a complete Tibetan SMS sending and receiving function. Among them, the complete and friendly interface in all Tibetan means: the interface information is accurate and error-free, and the dot-matrix fonts are clearly identifiable. The meaning of the easy-to-learn and easy-to-use Tibetan input method is: the input method can be easily mastered without special training. The meaning of the complete Tibetan short message sending and receiving function is: it has a short message transmission platform based on the relevant Tibetan information exchange coding standards.

As shown in Figure 1, Tibetan letters are arranged on 9 keys to complete the division of Tibetan letters. The Tibetan input system is installed in the corresponding equipment, mainly through the application of Tibetan character partitioning and indexing technology to realize Tibetan input. The designed input method conforms to the characteristics of Tibetan, and through the partitioning and indexing technology of Tibetan characters, it reduces the repetition code rate during Tibetan entry, and the repetition code can be up to 9 characters, which realizes the rapid entry of Tibetan. Due to the limitation of handheld electronic terminals/mobile phone keyboard keys, if Tibetan partition and index technology are not used, the repetition rate of Tibetan characters will be greatly increased, thereby increasing the difficulty of Tibetan input and reducing the input speed. The specific input steps are as follows: step a, partition Tibetan letters, and place Tibetan letters on 9 keys; step b, the system will automatically detect the input key value, and search the input method key value index table to obtain the key The start address of all words that value forms in the input method code table; Step c, calculate the end address of all words corresponding to this key value in the code table by subtracting one from the start address of the next key value; Step d, read Get the codes of all characters within the search range, search the dot matrix font library according to the codes, and display the characters; step e, determine the selected word according to the user's choice, and the system waits for the user to choose, thereby realizing the input of Tibetan.

See Figure 3 for the specific input process. In the input process shown in Figure 3, the division of the Tibetan alphabet is divided into 30 areas according to the difference of the base character, each area contains the base character and all its combined characters; the Tibetan input installed in the device The system includes an input interface program, an index table and an input method code table.

After Tibetan input, the system will display the input characters, as shown in Figure 2. In order to display the Tibetan language, a Tibetan dot matrix font library with an aspect ratio of 2:1 is specially designed and generated, which is most in line with the characteristics of the Tibetan font. The Chinese character dot matrix used in handheld electronic terminals/mobile phones is generally 16×16, which conforms to the font characteristics of Chinese characters. If the Tibetan character library directly adopts the 16×16 dot matrix font library, it will greatly reduce the aesthetics of the Tibetan output of the handheld electronic terminal/mobile phone. For this reason, the technical problem that it is difficult to generate Tibetan dot matrix characters in the range of 16×8 dot matrix is solved, and a beautiful 16×8 Tibetan dot matrix font library is produced.

Fig. 3 shows the flow chart of making code font library, according to Fig. 3, the coding method of Tibetan text short message in the used index table and input method code table is: also according to the difference of Tibetan text base character, Tibetan text is divided into 30 Each area contains a base character and all the combined characters of the base character; in each area, all the combined characters of the base character are exhausted, and all the combined characters follow the UNICODE standard The index range of 0x0080-0x00FF is set as 0x0080-0x00FF; the transmission mode of the combination word is expressed as the UNICODE of the base word + the index of the combination word of the base word; the 0 index 0x0080 is free, and the index range starts from 0x0081. For the comparison table of letters and codes, see the table below: Table 1

  Comparison table of 30 consonant letters in Tibetan and UNICODE international standard encoding

Fig. 5 shows the decoding flowchart of short message, when receiving Tibetan short message, wherein the decoding method of the Tibetan short message of index table and input method code list is: receive the short message of UNICODE encoding; Judge whether UNICODE encoding It is a short message in Tibetan; if it is, judge whether the range of the latter code is within 0x0080-0x00FF; if it is within the range of 0x0080-0x00FF, determine its code according to the combination of 4 bytes of Tibetan characters; The code is displayed in dot matrix by searching the dot matrix font library.

When it is judged that the encoding of UNICODE is not Tibetan, it is handed over to other corresponding writing systems for processing. Wherein if judge the last yard is not in the scope of 0x0080-0x00FF, just determine its coding according to the standard Tibetan mode of 2 bytes (being Tibetan basic characters), finally the received Tibetan short message is displayed. In the above embodiments, the encoding address is the empty code area of UNICODE encoding, and other encoding addresses may also be used for the encoding.

The device using the above input and display method is any handheld electronic terminal or mobile phone.

In addition, based on the above content, a unique and efficient coding and decoding technology for the handheld electronic terminal/mobile phone Tibetan SMS platform has been designed. This technology can be used to build a Tibetan SMS platform to realize the smooth sending and receiving of Tibetan SMS.

This technology can be used to develop various Tibetan-language handheld electronic terminals/mobile phones with full-Tibetan interface and Tibetan text message sending and receiving functions. The Tibetan population in my country is nearly 5 million. If 40% of the population uses various Tibetan-language handheld electronic terminals/mobile phones, there will be a market of 2 million units. In addition, there is a huge market for other extended products and value-added services. The development of Tibetan-language handheld electronic terminals/mobile phones can not only fill the gaps in this field at home and abroad, but also further open up potential markets for electronic products in Tibetan-language areas at home and abroad, promote the development of the communication industry in Tibetan areas in my country, and enhance the informatization of Tibetan areas in my country level.
