Abstract:
1. A decoding method to decode encoded data, the method comprising: comparing, by an error detection/processing unit, encoding status information with decoding status information by receiving encoded data and the encoding status information of at least one synchronization point set in every predetermined period to detect a transmission error and to obtain the decoding status information of a corresponding at least one synchronization point while decoding the encoded data; and continuing, by a decoding unit, to decode the received data if the encoding status information of the at least one synchronization point is the same as the decoding status information of the corresponding at least one synchronization point, and recovering, by the error detection/processing unit, previously decoded data before a previous synchronization point by detecting a transmission error region between the corresponding at least one synchronization point and the previous synchronization point if the encoding status information is different from the decoding status information.
