A streaming system includes an authoring unit, a stream server and a client terminal. The authoring unit generates a file composed of encrypted contents data and the ancillary information at least containing the packetizing control information for generating an RTP packet, a non-encrypted codec dependent header made up of the information pertinent to encoded contents data, and the encryption information for decrypting the encrypted contents data form packet to packet. The streaming server packetizes the encrypted contents data along with at least the codec dependent header and distributes the resulting data as a stream. The client terminal refers to the codec dependent header of the received packet, re-assembles the packet, and decrypts the encrypted contents data of the re-assembled packet to generate contents data.

Streaming system and streaming method

This invention relates to an information-processing apparatus for transmitting streaming data through a network, including: an addition element for adding information used for carrying out processing on streaming data to the streaming data; a storage element for storing the streaming data and the information added to the streaming data by the addition element; and a transmission element for transmitting the streaming data which is stored by the storage element and which includes the information.

Information processing apparatus and method for decoding encoded data

In a network implemented based on IEEE 1394, when an HDD is connected to a personal computer via an IEEE 1394 connection unit and a GUID terminal connection unit, the HDD obtains a GUID via the GUID terminal connection unit. When the personal computer requests acquisition of an access right, the HDD obtains a GUID via the IEEE 1394 connection unit, and compares it with the GUID obtained via the GUID terminal connection unit, and since the GUIDs match, the HDD assigns an access right to the personal computer. Even if another personal computer not connected to the HDD via the GUID terminal connection unit, transmits a GUID to the HDD via the IEEE 1394 connection unit, because the GUID differs from that of the personal computer connected to the HDD via the GUID terminal connection unit, an access right is not assigned to the personal computer not connected to the HDD via the GUID terminal connection unit.
