Embodiment Construction

[0032] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0033] According to the present invention, a block of memory is applied for as a buffer for storing coded streams. According to the content described in ASN1, each IE is encoded in turn, and when the OPENTYPE type is encountered, it is processed according to the following description:

[0034] The next byte to be stored in the encoding buffer is called the current byte. When encoding the OPENTYPE content, the encoding of the content is still stored in the current buffer, and the starting position is several bytes behind the current byte. After the encoding of the content is completed, the length of the PER (compression encoding rule) code stream is obtained, and the length is judged. If the length is between 0-127, the length encoding occupies one byte; if the len...

Abstract

The invention discloses an encoding process method which comprises: storing and arranging the length to the open type data unit in the encoding buffer area during the encoding course; encoding the open type data, storing it after the arranging length, capturing the open type data length at the same time; moving the encoding by the length of the open type data.

Description

technical field [0001] The invention relates to a network communication technology, in particular to a coding processing method. Background technique [0002] OPENTYPE (Open Type) is a data type described in ASN1 (Abstract Syntax Name), meaning that the data type and length are variable. When encoding, the code stream of this data type is divided into two parts, first encode the length of the encoded code stream of this data type, and then encode the text of the data. The following example illustrates: [0003] IE1: SEQUENCE IE2: SEQUENCE IE3: OPENTYPE [0004] Code 1 Code 2 Encode 3-length encoding Code 3 [0005] If the encoding (coding 3) length of IE3 content is between 0-127, then its length encoding occupies 1 byte; if the encoding (coding 3) length of IE3 content is between 128-16383 bytes, then it The length encoding of the content occupies 2 bytes; if the encoding (encoding 3) of the IE3 content is longer...
