The present invention provides a device and a method for accurately and efficiently controlling an access from an external network to an internal network. Both a client device connectable to the external network and an application gateway store shared secret information (Secret) including a client ID: GUID(C) as an ID generated by the client and a server ID: GUID(S) as an ID generated by the application gateway in respective storage units. In response to an access request from the client, the application gateway determines whether the client has appropriate shared secret information (Secret) so as to determine an access right. With this configuration, a right of access from the external network to the internal network, such as a home network, can be efficiently and accurately determined.

Access control processing method

The present invention provides an apparatus and method capable of efficiently sending an event corresponding to content to be transmitted from a server to each client. A content providing server assigns a session ID to each client on condition that the server receives an event notification request, which specifies an event URL, from the client and then manages an event notification process on the basis of the event URL and the session ID. When respectively transmitting pieces of content to a plurality of clients, the server determines event information to be transmitted on the basis of each event URL regarding the corresponding piece of content and controls event notification timing for each client on the basis of the corresponding session ID. According to the present configuration, the load of managing data in the event notification process on the server can be reduced and a correct event synchronized with transmission content can be sent to each client.

Information processing apparatus and content information processing method for transmitting content and event information to a client

Apparatus and a method are provided, which efficiently and properly execute information update processing and content reproduction processing based on transmission processing of content information from a server to a client. The server owning content attribute information extracts metadata based on an information acquisition request from the client, to generate the content information based on property information which is a component of the metadata, and for each property, sets data editing information allowed by each piece of the property information to transmit to the client. Furthermore, the server generates the content information including data mode information by which processing capability in a device on the client side can be judged, such as record quality level information and codec information, as the data mode information of the contents.

Information processing apparatus and information processing method, and computer program

The present invention provides a device and a method enabling a client connected to an external network to efficiently obtain information about servers connected to an internal network. An information processing device serving as an application gateway connected at an interface between the external network and the internal network performs a server information obtaining process about connected servers through the internal network in response to a request for obtaining information about the servers connected to the internal network transmitted from the client connected to the external network, generates a device list based on the obtained server information, and transmits the device list to the client through the external network. With this configuration, the client connected to the external network can efficiently obtain information about the servers connected to the internal network.

There are provided an apparatus and method that generate a MAC list that serves as an access control list efficiently without burdening a user. A MAC list registration processing request packet is automatically transmitted by using as a trigger either a power-on process of the power source of a client apparatus connected to a network or an activation process of a specific application, e.g., an execution application for services using a home network. A server performs a registration process by acquiring information such as a MAC address from the received packet in accordance with a state of empty slots in the MAC list. According to this configuration, it is possible to easily and correctly generate the MAC list, which serves as the access control list, without burdening a user.

Information processing device, server client system, method, and computer program

An apparatus and a method are provided, which enable to perform an improved management processing based on an identifier information of a content on a server. The content providing server sets content-associated unique identifier information as property information that is a component of content-associated metadata, maintains the unique identifier information as content-associated metadata without changing the unique identifier information even if the logical/physical position of a content stored in the storage unit is changed, and maintains a setting value of unique identifier information, which is set associated with a received content, as metadata associated with the received content without changing the setting value of the unique identifier information. By this configuration, even if a content is moved between servers, a client can acquire the content based on the unique identifier.

An apparatus and a method capable of efficiently and accurately constructing an access control configuration having high security are realized. Only the MAC address of a controller (client)authorized by a user is authenticated and registered in a MAC address table of a device, and the deviceperforms MAC address filtering for permitting access by the controller(client) which is authenticated and registered in the MAC address table. Furthermore, by making a registration completion notification and by performing version adjustment, a reliable access control configuration is constructed. The device authentication apparatusavoids access from an unauthorized party which is not authenticated and registered, and makes the presence of a server not known to the controller which attempts to illegally perform device authentication. Therefore, access control with high security is realized.

Content that is appropriate according to a specification of client equipment is distributed without having to prepare content of a plurality of formats. When a data list request is received from a client, a server sets a content URL and conversion identification information indicating that the content is original content for content that does not require data conversion. In the case of content for which data conversion is necessary, a virtual URL embedded with data conversion specifying information and conversion identification information indicating the necessity of conversion are set the URL and returned to the client. The server then receives the URL from the client for analysis. If there is no data conversion specifying information, the content is transmitted as it. If data conversion specifying information is embedded, the content is sent to the client after data conversion in accordance with the data conversion specifying information.

An apparatus and a method which enable to execute different access controls based on setting modes are realized. A MAC address table in which a manually registered client MAC address and an automatically registered client MAC address are registered in forms to be able to distinguish each other is set. If an access control mode is an automatic registration access control mode, a MAC addresses of an access requesting client is registered until the number of the MAC address reaches a defined limit number of registration: N of the MAC address table, and the access is allowed under the condition of the registration; or if the access control mode is a registered device access control mode, the access is allowed under the condition that the client MAC address is registered in the MAC address table as the manually registered MAC address.
