Patent ID: 6996122

Claim:
A decoding device for decoding a bit stream including a plurality of packets, in which data corresponding to an access unit includes a first data portion and a second data portion, the decoding device comprising: a packet regeneration section for receiving the bit stream including the plurality of packets, and producing a plurality of new packets from the received bit stream; a storage section for storing the plurality of new packets produced by the packet regeneration section; a read control section for receiving a control signal indicating a reproduction operation mode for the bit stream, producing an address signal according to the reproduction operation mode which is indicated by the control signal, outputting the produce address signal to the storage section, and reading, according to the address signal, the plurality of packets data which are stored in the storage section; and a combining section for decoding the read signal at the read control section; wherein the packet regeneration section, in the case where one access unit which is a minimum data unit is decodable individually, has the first data portion included in the first packet of the bit stream and the second data portion included in the second packet following the first packet, combines the first data portion and the second data portion, and produces a new packet including information indicating a length of the data corresponding to the access unit; and wherein the read control section, in the case where the control signal indicates a skip regeneration operation mode, by using information indicating a length of the data corresponding to the access unit, reads the plurality of new packets from the storage section so as to skip at least one of the plurality of new packets.
