ABSTRACT:
A decoding start controller is capable of appropriately decoding pictures up to the final picture, even if the amount of the data stored in a bit-stream buffer is reduced, as a result of partial storage of the data in an internal local buffer. Further, the decoding start controller is capable of decoding extremely short bit-stream data. If completion information, which is sent from an input side of the bit-stream data and represents completion of input of the bit-stream data, is detected, a decoding start instruction signal is output to a variable-length decoder regardless of a value of VBV occupancy. In short, when the amount of the data stored in the bit-stream buffer connected to the decoder having the decoding start controller, is equal or greater than the value of VBV occupancy, the decoding start instruction signal will usually be sent to the variable-length decoder: namely, so-called decoding start control operation based on value of VBV occupancy. If the completion information is detected, the decoding start control operation based on the value of VBV occupancy is interrupted, and the decoding start instruction signal is output.
