A digital video data decoding apparatus and a control method therefor are disclosed. A plurality of synchronization patterns are stored, and the synchronization pattern of the reproduced incoming data is compared with a stored synchronization pattern. Therefore, even if the synchronization pattern is altered, the altered synchronization pattern can be detected. Further, the header data and the user data can be extracted from the error-corrected data, and they are stored in the header data buffer and the user data buffer. Then they are outputted directly to the system by utilizing the direct memory accessing section. Consequently, the data processing amount of the CPU is reduced, thereby improving the data processing speed.
