Patent ID: 7714752

Claim:
An integrated circuit for receiving coded audio data and coded image data, the coded image data being obtained by coding image data of blocks, the image data of blocks indicating a two-dimensional array of transform coefficients, said integrated circuit comprising: an audio processing unit configured to decode the coded audio data; an image decoding unit configured to decode the coded image data; and a CPU, wherein the coded image data includes a coded run value and a coded level value, wherein the coded run value is obtained by coding a run value which is a value of a number of successive zero-value transform coefficients before a non-zero value transform coefficient, wherein the coded level value is obtained by coding a level value which is a value of the non-zero value transform coefficient, and wherein the image decoding unit: calculates a number of undecoded zero-value transform coefficients, selects a table in accordance with the calculated number, decodes the coded run value by using the selected table, decodes the coded level value, and inverse scans the decoded run value and the decoded level value into a two-dimensional array of transform coefficients.
