Abstract: In various examples, a system comprising at least one circuit to detect whether a fault has occurred during performance of an operation by the at least one circuit. In at least some embodiments, the at least one circuit generates error detecting values and determines a fault has occurred when the error detecting values do not match predetermined error detecting data.

Abstract: A system and a method for decoding a video is disclosed by the present invention. The system comprises a controller, a parser and a decoder, wherein the controller is used for sending a control command to the parser and receiving a status report from the parser; the parser is used for parsing a video stream according to the control command and sending a parsed result to the decoder; and the decoder is used for decoding the parsed result. By using the system and the method for decoding a video provided by the present invention, errors in a video stream can be concealed during the decoding process of the video, and then a desired video output effect can be achieved at a receiving end.
