Abstract: New description information that can be used for the playback and management of video data is generated. A photographing device (1) is provided with: a target information acquisition unit (17) that acquires position information indicating the position of a predetermined object within a video; and a resource information generation unit (18) that generates resource information including the position information, as description information relating to data of the video.

Abstract: A data broadcasting processor (230) of a television receiver (200) obtains carousel data and an event message. The processor (230) reproduces each data component of the carousel data in a regular condition. During a period indicated by reproduction period information in the event message, the processor (230) reproduces a data component that includes information of higher value and that is included in the event message, instead of one of the data components which are being reproduced.

Abstract: A content transmission unit (22) is provided that performs chunk transfer of a segment to a client (2) in subsegment unit, the subsegment being formed by dividing the segment into a plurality of pieces after receiving a request requiring transmission of the segment from the client (2).

Abstract: To realize a display processing device which is able to easily specify an acquisition destination of a partial video which the viewer desires to display in a specified display region. A video acquisition processing section (220) of a television (200) acquires MPD data (metadata) in which an identifier and an acquisition destination are indicated in association concerning each of a plurality of partial videos. The respective identifiers of the plurality of partial videos are identifiers which are able to specify the identifier of the partial video adjacent to the partial video without referencing other information.

Abstract: A device (100) includes a reception unit (110) that receives a program accompanied by a main advertisement from a device (300), a processing unit (120) that displays a program image on a display unit (140), and an engine (131) that displays the main advertisement on the display unit (140). The engine (131) transmits control information indicating a method of controlling displaying a related-advertisement to a sub-device (200) that receives the related-advertisement related to the main advertisement from a server (400) and displays the received related-advertisement.

Abstract: A server is provided with a video supplier which supplies a captured video of a camera to a client, and the supplier supplies to the client an MPD in which a range of parameter values supported by the camera is indicated.

Abstract: A content transmission unit (22) is provided that performs chunk transfer of a segment to a client (2) in subsegment unit, the subsegment being formed by dividing the segment into a plurality of pieces after receiving a request requiring transmission of the segment from the client (2).

Abstract: A server (1) transmitting content of an MPEG-DASH standard to a client (2), includes a throughput measurement section (23) that measures a throughput of the server (1), an event information addition section (24) that generates obtainment destination switching instruction information instructing to switch an obtainment destination of the content to another content transmission device when the throughput is a predetermined value or more, and a content transmission section (22) that transmits segment data together with the obtainment destination switching instruction information. Hereby, the most suitable adaptive streaming is executed in real time.

Abstract: A playing device (200) includes a segment conversion unit (240) that converts a plurality of segments having a short time length and forming a live broadcast program into a fewer number of segments with a long time length for recording and playing and records the fewer number of segments in a storage unit (250) and a control information conversion unit (230) that converts control information including each piece of playing information of the plurality of segments into control information including each piece of playing information of the fewer number of segments. Thus, content can be appropriately processed for recording and playing.

Abstract: Provided is a presentation control apparatus that is enabled to control a presentation form of video content on each device so that the video content is presented in a fashion reflecting a content provider's intention. Based on metadata transmitted from a transmitter apparatus, a component separator of a television receiver selects from two devices including the television receiver and a tablet terminal a device on which a video component is to be presented and causes the selected one or two devices to present the video component.

Abstract: A secondary delivery server includes a route determination unit that determines a delivery route of each component by using component management information that contains route information used to identify a delivery route of the component, and a delivery control unit that delivers the component using the delivery route determined by the route determination unit.

Abstract: An illumination device detecting section (6) detects data on the position of each illumination device (7) installed in the audio-visual environment space for a viewer. An illumination control data generating section (9) generates illumination control data for controlling each illumination device installed in the audio-visual environment space for the viewer, with use of the data on the position of each illumination device (7). The illumination control data allows suitable control of each illumination device installed in the audio-visual environment space for the viewer, in correspondence with its installation position, thereby improving the realistic atmosphere obtained by the viewer.
