Abstract
The proposed variable length coder can detect the start codes appropriately, while reducing the circuit scale thereof. The variable length code decoding apparatus, comprises: an interface section (2) having a plurality of registers (R20, R21, R22) each having a predetermined number of bits, for storing variable length code data in each of the registers in first-in first-out status; a shift circuit (3) for receiving data transferred from a predetermined number of the adjacent registers of the interface section and for shifting the received data by a number of bits corresponding to an applied shift signal, to select a start code head; and a start code detecting circuit (6) for executing detection operation by receiving data supplied from a predetermined number of the adjacent registers of the interface section, by detecting presence or absence of a start code on the basis the received data kept in byte-aligned status to output a start code presence and absence signal, and by outputting a start code shift length signal indicative of a byte from which a head bit of the start code begins in unit of byte, the start code shift length signal being applied to the shift circuit as the shift signal.
