Problems solved by technology

[0003] The purpose of the present invention is to overcome and solve the problem that the existing e-book reader and its electronic text compression and decompression technology can only be decompressed from the beginning, resulting in a significant delay in system response, and the compression technology adopted does not support the "partial decompression function". ", so that the average response speed of the reading request for random position content in the electronic text is slow, the storage space cannot be fully utilized, and the shortcomings and problems of storing larger and more e-books are researched and invented. A kind of e-book reading machine , it can use the electronic text compression technology that supports the "partial decompression" function, can make full use of the storage space, can store larger and more e-books, make the content that users can read richer, and can make the electronic text E-book reading machine and its electronic text compression and decompression method with greatly accelerated average response speed to reading requirements of content in random positions

Abstract

The electronic book reading machine consists of casing, liquid crystal display screen, key array, computer interface, battery compartment and circuit board connected together. Its compression method supports blocked compression and partial decompression. The reading machine decompresses the compressed text to the present reading position and displays text in its display screen; and the partial decompression is direct decompression after equal-width cutting. The "blocked compression" of the present invention can utilize the memory space fully and increase the length and the number of the stored text greatly. The "partial decompression" makes it possible to decompress the required content randomly and this raises the responding speed greatly. The electronic reading machine can be operated easily and flexibly.

Description

(1) Technical field: [0001] The invention relates to an electronic book reading machine and an electronic text compression and decompression method thereof, belonging to high-performance consumer electronic products and block compression and partial decompression technologies. (two) background technology: [0002] For a compression method, if it can provide a relatively stable compression ratio, the longer the length of the compressed file is, the greater the reduction in the length of the compressed file will be. Therefore, the files to be compressed in practice are generally relatively large. For the unequal-length encoding method, even if only the last part of the non-text is used, the text must be decompressed from the beginning. In this case, a significant delay in system response is caused. Especially for embedded systems and microcomputer portable devices with limited data processing and storage capabilities, this response delay will be quite obvious. Therefore, we p...
