When audio dubbing is implemented, error correction is performed for each ECC block. The invention provides a representation of video data that can be used to assess agreement between the data and a fitting model for a particular parameterization of the data. By sensing in real time whether or not the TS packets that are RS decoded by the external decoder are synchronized, when the TS packets are not synchronized, they are resynchronized and output so that a normal decoding operation can be performed. The signal charge is thenceforth transferred to the vertical transfer lines and a video signal is output from the CCD. The backflow into the inactive branch is prevented by maintaining the injection nozzle against the mold until molding is complete. The ECU determines whether the object is within a first object range and provides a first external warning when the object is within the first object range and determines whether the object is within a second object range and provides a second external warning when the object is within the second object range.
