Abstract
A decoding circuit applied to a multimedia apparatus is provided. The decoding circuit is for decoding encoded data to generate system information, and includes multiple processing circuits and a determination circuit. The multiple processing circuits individually process the encoded data to generate multiple processed signals, and respectively correspond to multiple bit combinations of a part of the system information. The determination circuit determines the system information according to the multiple processed signals.
