Abstract
The present application provides a scrambling device and a scrambling method. The scrambling device includes a data acquisition module, a judging module, a first scrambling module, a second scrambling module and an output module. The judging module judges data signals and transmits different data signals to the corresponding scrambling modules, so as to scramble the data signals, and finally obtain required output signals, thereby effectively increasing a scrambling rate of the scrambling device.
Claims13
A scrambling device, comprising:
- a data acquisition module configured to acquire an original data signal of a display image;
- a judging module configured to judge the original data signal, to output a first control signal when the original data signal is a high-level signal, and to output a second control signal when the original data signal is a low-level signal, wherein a number of bits of the first control signal is different from a number of bits of the second control signal;
- a first scrambling module configured to receive the first control signal and scramble the first control signal to obtain a first scrambled data signal;
- a second scrambling module configured to receive the second control signal and scramble the second control signal to obtain a second scrambled data signal;
- and
- an output module configured to receive and output the first scrambled data signal or the second scrambled data signal;
- wherein the first control signal and the second control signal are generated independently from each other.

A scrambling method, comprising the following steps:
- acquiring an original data signal of a display image;
- judging the original data signal, outputting a first control signal when the original data signal is a high-level signal, and outputting a second control signal when the original data signal is a low-level signal;
- receiving the first control signal and the second control signal, and scrambling the first control signal and the second control signal, wherein the first control signal is scrambled to obtain a first scrambled data signal, and when the second control signal is scrambled, the second control signal is inverted and then scrambled to obtain a second scrambled data signal;
- and
- receiving and outputting the first scrambled data signal and the second scrambled data signal;
- wherein a number of bits of the first control signal is different from a number of bits of the second control signal;
- wherein the first control signal and the second control signal are generated independently from each other.
