Title:
ENCODING DEVICE
Document Type and Number:
Japanese Patent JP2008103898
Kind Code:
A
Abstract:
To provide an encoding technique which has good code efficiency and can easily achieve synchronization with encoded data.
An encoding device 150 converts two-bit information data into four-bit encoded data according to a predetermined code rule. According to the code rule that the encoding device uses, one of four kinds of bit streams that the information data possibly include is converted into a four-bit bit stream wherein two bits at successive bit positions have values of "1" and a four-bit bit stream wherein all bits have values of "0" alternately. Other kinds of bit streams are converted into four-bit bit streams wherein only one bit has a value of "1" so that the bit streams having been encoded are different from one another.
