Patent ID: 8331455

Claim:
A decoding device, comprising: a syntax parsing unit configured to syntax parse a bit stream using description information in order to generate a plurality of element information, and store the plurality of element information in an element information storing unit, the description information and the bit stream being provided by an encoder; a connection controlling unit configured to successively select a plurality of functional units, determine a performing sequence between the selected plurality of functional units according to the description information, and selectively input element information from the plurality of element information stored in the element information storing unit into the selected plurality of functional units; and a processing unit comprising at least the plurality of functional units, wherein the plurality of functional units are configured to perform a process according to the performance sequence and by using the element information inputted by the connection controlling unit, and output corresponding result data, and wherein the description information comprises: a syntax element table (SET) including process generating information related to a bit stream syntax and element information corresponding to the bit stream syntax; a syntax rule table (S-RT) including a connection rule between the bit stream syntax; a control signal and text information table (CSCIT) including details about the plurality of element information stored in the element information storing unit; a functional unit list (FL) including a list of functional units including the plurality of functional units; a functional unit-rule table (F-RT) including rules for successively selecting the plurality of functional units; and a function unit-CSCIT (FU-CSCIT) identifying the element information to be selectively input into the selected plurality of functional units.
