Type-dependent coding method wigh type control

Abstract

The invention relates to a kenel depending encoding method that refers to kenel controlling. It is used kenel depending encoding mehod of combination kenel classificatioin and digital aggregate concept. The DC control section effect would be improved by adding kenel control section in encoding program in the fixed area. The method includes the following steps: continuously running digital encoding program corresponding to data; running counting number accumulation program before reaching the preset interval; when reached at the preset interval, it includes the following steps: inserting preset kenel control digital encoding program and running counting number return to zero program. Before all the data word finished encoding, repeat step a to step c. The invention increases the selectable on digital character, and improves the capacity of DC section.

Description

technical field [0001] The present invention relates to an encoding method for generating encoded data, in particular to an encoding method applied in a type-dependent encoding mechanism, which utilizes the concept of type control to improve the DC component control (DC-Free) capability of encoding. Background technique [0002] The encoding mechanism generally used in recording media refers to the data words that are originally intended to be directly stored in the recording medium, first calculated through the encoding technology of specific rules, and then a series of digital strings that meet specific rules are generated, so It can be recorded in the recording medium in a more efficient form, and when it is necessary to use it, by executing the reverse program that meets specific rules, the digital string can be restored to the original data word for use. [0003] Under the code design method of applying the Run Length Limit (RLL) method, generally there will be a (d, k)...

AI Technical Summary

Problems solved by technology

Although compared with the two encoding methods mentioned above, it can improve the overall encoding rate, but it also makes this method have fewer optional digital words in the encoding process, resulting in a much lower DC component control capability.

Although the DC component control capability can be overcome by increasing the length of lookahead in the encoding program, the effect of this processing method is limited and it will increase the complexity of the calculation process in the encoding program
