Description
Technical Field
The invention belongs to the field of set top boxes, and particularly relates to a method for displaying Burmese by a set top box.
Background
ASCII (American Standard Code for Information Interchange ) is a set of coding systems based on latin letters. The coding range is 0x00 to 0x7F, and is mainly used for displaying modern English. The Extended version of EASCII (Extended ASCII) can partially support other western European languages, and the EASCII is formed by extending an ASCII code from 7 bits to 8 bits. The EASCII codes range from 0x00 to 0xFF, and the extended symbols include table symbols, calculation symbols, greek letters and special pull Ding Fuhao.
Unicode (Unicode) is an industry standard in the field of computer science, including character sets, coding schemes, and the like. Unicode is generated to solve the limitations of traditional character coding schemes, and sets a uniform and unique binary code for each character in each language so as to meet the requirements of cross-language and cross-platform text conversion and processing. Unicode is implemented differently than coding. Unicode encoding of a character is deterministic. However, in the actual transmission process, the implementation of Unicode coding is different due to the inconsistent design of different system platforms and for the purpose of space saving.
The implementation of Unicode is called Unicode conversion format (Unicode Transformation Format, abbreviated UTF). UTF-8 is one of the most commonly seen coding formats. This is a variable length coding format, the purpose of which is to save memory space. All valid encoding points in the Unicode character set are encoded with one to four bytes.
UTF-8 for backward compatibility with ASCII code, the first 128 characters in Unicode are encoded with a single byte of the same binary value as the ASCII code, and the characters are in one-to-one correspondence with the characters of the ASCII code, which makes the original software for processing ASCII characters continue to be used without or with little modification. UTF-8 has been the most dominant form of encoding on the world Wide Web since 2009. In Unicode, a field is defined as a range of a set of consecutive code bits. The segments are given unique names and there is no overlap between segments. For example:
basic Latin letters (Basic Latin) range u+0000 to u+007F;
latin letters Supplement-1 (Latin-1 Supplement) segment ranges from U+0080 to U+00FF;
braille Patterns (Braille Patterns) range from U+2800 to U+28FF;
the region of the unified ideogram (CJK Unified Ideographs) of the middle Japanese and Korean ranges from U+4E00 to U+9FFF.
Burmese is a character belonging to the salomide family, and is characterized by being round in writing. The number of characters is large, and most of the characters are formed by combining hundreds of graphic characters. For a long time, there is no official unified code standard for Burmese for historical reasons, and many font manufacturers have devised to release different Burmese codes, including Win Innwa, myazedi, zawgyi, etc. Wherein Win Innwa is the Burmese font which circulates in the Burmese nationwide at the earliest, and Win Innwa is developed in an ASCII coding system for single-byte coding. Essentially, the English font is changed into a shape, and is incompatible with English, as follows, the corresponding relation between UTF-8 coding Latin characters and Win Innwa coding Burmese characters is as follows:
character encoding 0x21: english' ≡! 'Burmese' characterCharacter encoding 0x62: english 'b', burmese->Character encoding 0x63: english 'c', burmese->Although the burmese government has announced in 2019 that Unicode standards are uniformly adopted nationally, the burmese program operators still keep using Win Innwa to code the offered services in order to support the cost pressures of the products sold and the upgrade system. The program name, the electronic program list and the like of the operation program are all Win Innwa codes, an operator uses a private protocol to transmit Win Innwa character string codes, a start identifier is defined as '(', an end identifier is '))', and data between the start identifier and the end identifier is Win Innwa code character string. Typically, set top boxes use standard UTF-8 word libraries to support multi-language displays, and there are conflicts due to the incompatibility of Win Innwa coding with UTF-8 coding. Therefore, the Win Innwa word library cannot be directly used for displaying the Myanmar, the display of Latin characters is abnormal, the multi-language requirement of products cannot be met, the Win Innwa coded Myanmar and the UTF-8 coded character strings cannot be supported at the same time, and the product requirement of an Myanmar operator cannot be met.
The invention patent with the patent number 201010577378.X discloses a method for displaying Burmese by a set top box, which converts character strings of a Burmese character library on a PC into dot matrix data, simultaneously records the width and height data of each character string into the dot matrix character library, registers character strings which are required to be combined with other character strings in the Burmese character library, and registers the initial coordinates and positions of the character strings which participate in the combination in the dot matrix character library; when the set top box is to perform the Burmese display, the required character string in the dot matrix character library is searched according to the character codes, the character data of the character string is taken out to obtain the width and height of the character string, the next character code to be combined is read, the required character string is taken out, and the combination is performed according to the initial coordinates and the position of the previous character string, so that the display of a complete Burmese character is completed. Although this method solves the problem of the display of the Burmese, by converting to a dot matrix word stock, a standard word stock processing program, such as a word size adjustment, cannot be used.
