20090010430 | Streaming system for distributing encrypted compressed image data, and streaming method therefor - The present invention is directed to a streaming system for encrypting compression-encoded image data to distribute it via network of a predetermined transport protocol, and a streaming server used in this system transmits, to a client terminal, on the RTP packet basis, stream data encrypted so that encryption is performed every encryption block size from the leading portion of each GOP without encrypting the last data having less than encryption block size. In this instance, portions of prior and/or posterior stream data are stored into an extended area of RTP header so that size of stream data transmitted every RTP packet is integral multiple of encryption block size. Further, size information of added prior additional data and/or posterior additional data are also stored into the extended area. This streaming server suppresses increase in size by encryption to have ability to support both real time production and down-load reproduction without replacement of encryption. | 01-08-2009 |
20100023980 | Information Processing Apparatus, Terminal Apparatus, and Program - An information processing apparatus includes a content purchase history storage unit in which a content purchase history for each user is stored, a metadata storage unit in which metadata of a plurality of contents is stored, and a metadata retrieval unit to retrieve, upon reception of a metadata retrieval request that is sent from a terminal apparatus of the user via a network and includes information for identifying a user and a retrieval condition, metadata of a content that meets the retrieval condition from the metadata storage unit, judge whether the content retrieved has already been purchased based on the content purchase history of the user that is stored in the content purchase history storage unit, and send a retrieval result of the metadata of the content that includes a judgment result to the terminal apparatus via the network as a metadata retrieval response. | 01-28-2010 |

20120311190 | COMMUNICATION NETWORK SYSTEM, GATEWAY, DATA COMMUNICATION METHOD AND PROGRAM PROVIDING MEDIUM - This invention relates to provide a communication network system, a gateway, and a data communication method, in which the gateway has an advanced functionality. A person who issues an access request can retrieve a desired access destination easily by the following configuration: functions of routing information providing and authentication processing are added to a gateway that performs protocol conversion between two different communication networks; when an access request is issued from a public communication network such as Internet to a terminal in a local (private) communication network connected to the gateway, a request terminal is authenticated to enable prevention of unauthorized data writing and reading; and an access request user who succeeded in the authentication is provided with an active terminal list comprising accessible terminal information, or with a user condition table. | 12-06-2012 |

20150312229 | STREAMING SYSTEM AND METHOD - 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. | 10-29-2015 |

20120128518 | SCROLL COMPRESSOR - A scroll compressor includes a back pressure chamber oil-feeding path for feeding lubricating oil from a high-pressure region to a back pressure chamber, and a compression chamber oil-feeding path for feeding lubricating oil from the back pressure chamber to a compression chamber. One phase in which the back pressure chamber oil-feeding path is communicated from the high-pressure region to the back pressure chamber and another phase in which the compression chamber oil-feeding path is communicated from the back pressure chamber to the compression chamber are shifted from each other, so that the back pressure chamber oil-feeding path and the compression chamber oil-feeding path are never put into the communicating state simultaneously. Thus, after a halt of the compressor, under-communication oil-feeding of the lubricating oil from the high-pressure region via the back pressure chamber to the compression chamber can be prevented, so that the lubricating oil in the liquid storage section is kept from decreasing and moreover the lubricating oil is kept from being filled into the compression chamber, make it possible to achieve a stable restart-up. | 05-24-2012 |
