A first acquisition unit acquires an event notification from an MFP and updates first device-status information. A transmission unit transmits the event notification and first reference-destination information. A switching unit switches a first access to the first reference-destination information to a second access to second reference-destination information. A second acquisition unit issues an acquisition request at a first interval, issues an acquisition request at a second interval in response to the event notification, acquires the second device-status information, and update the first device-status information.

A method for receiving data by a receiving station by using a multi-user multiple input multiple output (MU-MIMO) in a wireless local area network system, the method includes receiving, via a transceiver in the receiving station, a physical layer convergence procedure (PLCP) protocol data unit (PPDU) from a transmitting station, the PPDU including a bundled interface field, a modulation and coding scheme (MCS) index field and a data field, wherein the bundled interface field indicates a number of a plurality of spatial streams allocated to the receiving station among a plurality of receiving stations, and indicates a total number of spatial streams allocated to the plurality of receiving stations that receive the PPDU, and wherein the MCS index field indicates a same MCS index used for modulating and coding the plurality of spatial streams allocated to the receiving station; and demodulating and decoding, via a processor in the receiving station and by using an MCS scheme indicated by the MCS index field, the data field received via the plurality of spatial streams indicated by the bundled interface field.

A method for providing content from a first node to a second node using a satellite communications system includes receiving side information at a gateway in the satellite communications system. The side information may be transmitted from a subscriber terminal to the gateway via a first communication path that includes a satellite link. The method also includes determining at the gateway that the side information is associated with first content available at the first node, and determining at the gateway that second content is available from a source other than the first node. The method also includes generating output content using the second content and the side information. The output content may be substantially the same as the first content. The method also includes providing the output content to the second node via a second communication path that does not include the satellite link.

A method for providing security vulnerability information is provided. The method may include checking for the security vulnerability information product supplier servers. The method may further include sending alerts to a security vulnerability administrator associated with a client environment. Additionally, the method may include performing a security check on the security vulnerability administrator to authorize the security vulnerability administrator to receive the security vulnerability information. The method may also include authenticating customers associated with the client environment to authorize the customers to receive the security vulnerability information. The method may further include prompting the authorized security vulnerability administrator to acknowledge an information confidentiality reminder. The method may also include sending an audit record to the product supplier server. The method may further include presenting the security vulnerability information to the authorized security vulnerability administrator and the authorized customers associated with the client environment.

There is provided a device control apparatus which makes it possible to dispense with device monitoring (polling) by a client apparatus to thereby reduce traffic on a network. A device server 200 acquires, according to device information for identifying a device locally connected to the device server 200, at least one of a trigger detection algorithm and a definition file for monitoring a state change of the device identified based on the device information, and monitors the locally connected device based on at least one of the acquired trigger detection algorithm and definition file. Then, when a state change of the device is detected, the device server 200 sends a trigger notification indicative of the detection of the state change to a client PC 100 via a network 500, and starts a session with the client PC 100 in response to a connection request from the client PC 100 having received the trigger notification.

Methods, apparatuses, and computer program products for implementing interactive applications by storing and retrieving streaming video clips and associated metadata are described.

A method and a transmitting station for transmitting data by using a multi-user multiple input multiple output (MU-MIMO) in a wireless local area network system are discussed. The method according to an embodiment includes transmitting a physical layer convergence procedure (PLCP) protocol data unit (PPDU) including a bundled interface field, a modulation and coding scheme (MCS) index field and a data field. The bundled interface field indicates a number of at least one spatial stream allocated to each of a plurality of receiving stations and a total number of spatial streams allocated to the plurality of receiving stations. The MCS index field indicates a same MCS index used for modulating and coding the at least one spatial stream. The data field is modulated and coded by an MCS scheme indicated by the MCS index field and transmitted via the plurality of spatial streams indicated by the bundled interface field.
