Document Type and Number:
Japanese Patent JP2009135701
Kind Code:
A
Abstract:

To provide a moving picture reproducing apparatus which may be actualized in the structure simpler than that of the related art in order to reproduce pictures through conversion of resolution of input moving picture data.

The moving picture reproducing apparatus includes a data extracting unit (1) for extracting DCT coefficients of the required number from the DCT coefficients obtained by executing variable-length-decoding for each macro-block obtained by dividing the variable-length-encoded input moving picture data into the predetermined size, a moving picture decoding unit (2) for executing the predetermined decoding process to the extracted DCT coefficients, and a decoded data converting unit (3) for generating picture data of the predetermined resolution based on the decoded data output from the moving picture decoding unit (2).
