A system and method for video decoding, including decoding video data from an input Transport Stream (TS) bitstream, variable-length-decoding the decoded video data, and restoring pixel values of an original picture through an Inverse Quantization process, an Inverse Discrete Cosine Transform process, and an Motion Compensation process from the variable-length-decoded video data; analyzing characteristics of video data based on error information, header information, and macroblock information extracted from the decoded video data to generate analysis information and generating thumbnail image; storing the generated thumbnail image; generating meta data information based on the generated analysis information and controlling to store the generated meta data information; controlling to search the stored input TS bitstreams in the storage medium according to the stored meta data information; and controlling to store the generated thumbnail image, read the stored image, and display an Electronic Program Guide with the read thumbnail image.
