An information processing device includes a first display control unit configured to display together first content and second content, which is different from the first content, together, in a display area of a display unit. The information processing device further includes an identification unit configured to identify third content and fourth content on the basis of a viewing action for the first content and the second content. The information processing device further includes a second display control unit configured to display, in the display area, the third content as identified and the fourth content as identified. A degree of relevance between the third content and the fourth content is lower than a degree of relevance between the third content and the first content.

Information processing device, display system, and information processing method for displaying viewer-latent-interest-based content

A data processing device is a device that detects an abnormality in a facility disposed in a room or a sign thereof and includes an acquisition unit and a processing unit. The acquisition unit acquires processing target data. The processing target data is generated by recording an audio or a video inside the room. The processing unit processes a part of the processing target data (hereinafter, referred to as a processing target part) for generating facility information relating to a facility disposed inside the room. Then, the processing unit detects a reference timing that is a timing satisfying a reference condition set in advance and sets the processing target part using the reference timing.

Data processing device, data processing method, and program

A signage player includes: a time function configured to count an internal device time. The signage player also includes a time correction calculator configured to acquire a reference time from the outside, for example, an NTS server, at a timing determined in advance and synchronize the internal device time with the reference time; and a time corrector configured to calculate a time correction coefficient defined using a change rate of a time difference, an error change rate (Δ) between the reference time and the internal device time at a timing different from the timing determined in advance and calculate a corrected time acquired by correcting the internal device time using the time correction coefficient.

Reproduction device, time correction method, and program

A display control device includes a visual field determination unit configured to determine whether or not a display device for displaying content is included in a visual field of a person included in an image captured by an imaging device that images a region around the display device, a central visual field determination unit configured to determine whether or not the display device is included in a central visual field within the visual field, and a change determination unit configured to determine whether or not to temporarily change a display mode of the display device displaying first content before the content is switched from the first content displayed on the display device to second content to be subsequently displayed when it is determined that the display device is included in the visual field but is not included in the central visual field.

Display control device, display control method, and program

The present invention has a communication portion configured to establish an image transmission system for receiving an image signal from an image transmitting device via a network; and a connection information management portion configured to set the total number of the image transmission systems established for each of a plurality of the image transmitting devices as the number of connections, wherein the connection information management portion does not change the number of connections even if the image transmission system is disconnected, when the image transmitting device shifting into a power saving mode causes the image transmission system to be disconnected.

Method for controlling image and image display device

An image display device includes a communication device transmits a transmission request to each of the image transmission devices and receives a frame including differential data transmitted by each image transmission device in response to the transmission request. A measurement unit measures, for each image transmission device, a first required time interval, which is the time required from the start of transmission of the transmission request until the start of reception of the frame, and a second required time interval, which is the time required from the start of reception until the completion of reception of the frame. A control unit causes transmission requests to be sent to each of the image transmission devices at predetermined transmission intervals, causes measurement unit to measure the first and second required time intervals, and changes the transmission interval of the transmission request based on the measurement results.

Image display device, frame transmission interval control method, and image display system

An apparatus of the present invention for displaying an image comprises connected device controllerfor notifying one of a plurality of apparatuses Sto Sn for transmitting an image connected via a networkand that has made a first connection request after activation, of information that display authority that is a right to preferentially perform processing for displaying an image is granted and of information that image data may be transmitted at any time, and for notifying another one or more of the plurality of apparatuses for transmitting an image and that have made a connection request, of information that image data cannot be transmitted unless permitted.

Apparatus for displaying an image, system processing image data, and method of processing image data

An image displaying device with an image cache data storage unit, including: an image cache identifier generating unit that obtains a hash value of a fixed length from sampling data of original image data and generates an image cache identifier unique to said original image data based on the hash value of a fixed length; an image cache searching unit that checks whether image cache data to which the generated image cache identifier is added is stored in said image cache memory or not; and an image cache generating unit that, when the image cache data has been not stored in said image cache memory, generates image cache data by adding the image cache identifier generated by said image cache identifier generating unit to the original image data and stores the image cache data in said image cache memory.

Image displaying device having image cache memory

An image transmitting method is disclosed for reducing the load on a CPU of an image transmission apparatus. An image change monitoring unit provided in the image transmission apparatus monitors the latest image used to generate image data transmitted to an image reception apparatus via a network, and a subsequent image to determine whether or not the latest image has changed. An image capture unit captures the image after the image has changed to acquire the image when the image change monitoring unit determines that the latest image has changed.

Reduction in load of image transmission

An apparatus for transmitting image data through a network has an image rendering unit, an image processing device, a memory device, and an image transmitter. The image processing device is configured (a) to define a range surrounding an updated portion which has changed through displaying, of the displayed image sent from the image rendering unit, and to acquire position and range information of the defined range, (b) to compare the defined range with a range stored in the memory device, using the position and range information of the defined range and position and range information stored in the memory device, (c) to send the position and range information of the defined range to the memory device if there is no overlapping range between the compared ranges, and if there is an overlapping range between the compared ranges, to send position and range information of a new range surrounding the compared ranges to the memory device, and (d) when the image transmitter is ready for transmission through the network, to read image data of a latest image stored in the memory device, the image data corresponding to each item of the position and range information stored in the memory device at a time of transmission, to compress the image data in order to generate compressed image data, send the compressed image data to the memory device, and to initialize the position and range information stored in the memory device.
