Image processing apparatuses and information processing systems are disclosed. In one example, user information is generated on condition that a session is being established with a provision destination of a captured image, and the user information is provided to an information processing device that stores imaging location information. Alternatively, acquisition of imaging location information is permitted on the basis of permission information obtained from a provision destination on the condition that a session is being established with the provision destination of a captured image, the imaging location information provided from the information processing device associated with an imaging location is acquired in the permitted state, and the imaging location information and the user information are provided to an external device that verifies the user information.

Image processing that permits imaging operations with reference to user information

Provided is a signal processing device including a control information acquiring unit configured to acquire image control information regarding control of an image, an image receiver configured to selectively receive one or more images transmitted using multicast based on the image control information, one or more image processing units configured to perform an image process on an image received by the image receiver based on the image control information, and an image sender configured to transmit an image subjected to the image process by the image processing unit based on the image control information, the image being transmitted using multicast.

Signal processing device, signal processing method, and image transmission system

Provided is an image transmission system including an image control device, and at least two signal processing devices. The signal processing devices each include an image receiver configured to selectively receive one or more images transmitted using multicast based on image control information transmitted from the image control device, one or more image processing units configured to perform an image process on an image received by the image receiver based on the image control information, and an image sender configured to transmit an image subjected to the image process by the image processing unit based on the image control information, the image being transmitted using multicast.

Transmission and display of image signals based on multicast transmission

[Object] To provides a controller capable of switching a video so that the video is not distorted on the receiving side when the video is transmitted using IP multicast [Solution] There is provided a controller including a bandwidth reservation unit configured to, when an instruction given to a receiving device that receives a first video stream transmitted via IP multicast to receive a second video stream after receiving the first video stream is acquired, acquire information on a status of a network topology and a transmitted video stream and to reserve a network bandwidth for transmitting the second video stream in addition to the first video stream, and a reception instruction unit configured to send out an instruction to receive the second video stream to the receiving device by using the network bandwidth reserved by the bandwidth reservation unit.

Controller, control method, computer program, and video transmission system

An image delivery management server of present invention includes a delivery load amount acquiring portion that acquires a delivery load amount of an image that is delivered to a viewer's terminal connected via a network, and a delivery device determining portion that determines, based on the delivery load amount, a type or a quantity of a delivery device that performs image delivery to the viewer's terminal.

Image delivery management server and image delivery management system

There is provided an information processing device including, a screen control unit that causes a user terminal to display a position selection screen displaying a plurality of user positions where a user can be located in a virtual space and allowing a user to select one user position from the plurality of user positions, a data storage unit that stores a user list listing users having selected each user position with respect to each user position selected by using the position selection screen; and a contents processing unit that processes contents to be delivered to the user terminal according to a positional relationship between users represented by the user list stored in the data storage unit.

Information processing device, contents processing method and program

A receiving device includes: a buffer temporarily accumulating receive data received through a network; a data processing means for processing the receive data; a short-time variation value acquisition means for acquiring a short-time variation value indicating variation of accumulated quantity of the receive data sequentially accumulated in the buffer in a first unit time; a long-time variation value acquisition means for acquiring a long-time variation value indicating variation of accumulated quantity in a second unit time; and a clock control means for controlling a clock frequency for performing processing of the receive data by the data processing means in accordance with evaluation results of the acquired long-time variation value. The clock control means stops adjustment of the clock frequency when an error of the network or the receive data is detected, and starts the adjustment again after a given adjustment stop time passes from the detection of the error.

Receiving device, receiving method and program

Disclosed herein is a content viewing system including a content viewing apparatus, and a viewing approval apparatus used by a viewing approval party to perform an approval process. The content viewing apparatus includes: a viewing approval requesting section that transmits a viewing approval request to the viewing approval apparatus when it has been determined that approval for viewing of a content is necessary; and a content viewing control section that receives, from the viewing approval apparatus, an approval/disapproval response, and, if the approval/disapproval response indicates that the viewing of the content has been approved, enables the viewing of the content. The viewing approval apparatus includes: an output section that outputs information concerning the viewing approval request; an input section that accepts input of the approval/disapproval response; and an approval/disapproval response notification section that notifies the content viewing apparatus of the approval/disapproval response.

Content viewing system, content viewing apparatus, and viewing approval apparatus

A communication control apparatus selects an optimum terminal for an authentication device among a plurality of terminals that have completed authentication of the authentication device via wireless communication. The communication control apparatus has an information acquiring unit and a selecting unit. The information acquiring unit acquires address information and capability information of each of the plurality of terminals and identification information of the authentication device from each of the plurality of terminals. The selecting unit selects the optimum terminal having a capability of handling data addressed to the authentication device among the plurality of terminals on the basis of the capability information of the plurality of terminals and the identification information of the authentication device acquired by the information acquiring unit, when the address information and capability information of the plurality of terminals are acquired by the information acquiring unit.

Communication control apparatus and communication control system

In a data multiplexing/demultiplexing apparatus including a serial-to-parallel converter, a microprocessor and a memory, a data shift register inputs data from the memory by way of the microprocessor, a correction register stores a shift correction amount on a transmission path of the data shift register. A framing rule register stores a framing rule determined by the microprocessor, a counter, carries out a counting operation in accordance with the framing rule to an address information signal. A look-up table ROM outputs a selector selection signal in accordance with the address information signal, and a data selector distributes output data of the data shift register among a plurality of shift registers in accordance with the selector selection signal. The microprocessor analyzes data separated by the plurality of shift registers, performs a synchronism detecting operation and a protocol determining operation, and determines the framing rule.
