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: Different applications are activated for respective multiple programs. A component demultiplexing unit (34) that receives an MH-AIT (141) indicating an application corresponding to each of packages, a combining unit (38) and an audio decoding unit (36) that reproduce one of the packages, and a data broadcasting control unit (37) that controls an application corresponding to a package, which is being reproduced, by referring to the MH-AIT (141) are included.

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: To adaptively change an aspect ratio. A reproduction device (200) is provided with an aspect ratio changing section (212) that specifies an adjacent region that is combined with a basic region with reference to MPD data (221) in which the basic region and a plurality of adjacent regions adjacent to the basic region and with different shapes to one another are defined, and a reproduction section (213) that sets a region as a display object in which the basic region and the specified adjacent region are combined.

Abstract: A distribution apparatus (300A) includes a distribution unit (330) that distributes an AIT and a PIT of the same version together. Every time only a PIT (AIT) is updated, the distribution unit (330) distributes the updated version of this PIT (AIT), and also distributes an AIT (PIT) of version 00 indicating that a component will continue to be obtained or played back on the basis of the AIT (PIT) which is not updated.

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 distribution server (300) periodically distributes, during a live distribution of a content, MPDs of the contents to a client device (100). The distribution server (300) includes a metadata generating section (320) for generating an XML file containing URLs of media segments (MS) belonging to past Periods. The metadata generating section (320) also generates MPDs.

Abstract: A server (2) includes an index information generator (24) and an encoder (23). When a plurality of items of segment data (27) have been encoded up to predetermined sub segment data, the index information generator (24) generates index information (28) used for switching content, which serves as a playback subject, at this sub segment data. The encoder (23) causes a client (1) to obtain the index information (28) generated by the index information generator (24).

Abstract: A content distributing device in the present invention receives a request message to request to transmit content. Then, in a case where a device transmitted the request message is a relaying device for receiving the content thus requested and possessing and transferring the content to another device, the content distributing device transmits the content thus requested to the relaying device, or, in a case where a device transmitted the request message is a content playing device for playing the content thus requested, the content distributing device transmits, to the content playing device, an instruction to acquire the content from a relaying device which has transmitted before the content thus requested.

Abstract: Provided are a data transmission device, a method for transmitting data, an audio-video environment control device, a method for controlling audio-visual environment, an audio-video environment control system, wherein peripheral devices can be appropriately controlled in accordance with the layout of the peripheral devices in an actual audio-visual environment so that a high realistic sensation is obtained. A data reception device (20) receives a predetermined video data and/or audio data, identification information indicative of an arrangement pattern of peripheral devices (lighting devices) arranged in a virtual audio-visual environment space, lighting control data corresponding to the peripheral devices arranged in the virtual audio-visual environment space.

Abstract: Provided are a data transmission device, a data reception device, a method for transmitting data, a method for receiving data, and a method for controlling audio-visual environment that carry out the control of peripheral devices in consistence with contents producer's intention, thereby realizing the listening/viewing of the contents with a realistic sensation. The data transmission device is comprised of a video coding unit (101), an audio coding unit (102), an audio-visual environment control data coding unit (103), an audio-visual environment control data input unit (104), a data multiplexing unit (105) and a transmission unit (106).

Abstract: The apparatus includes an input selector 101 for selecting input video streams, a stream analyzer 102 for acquiring encoded information, a decoding section 103 for executing decoding processes, an output memory section 104 for recording decoded frame data, an output switching section 105 for selecting frame data to be output, a display output section 106 for outputting a display image on a display screen, a scheduling section 107 for assigning decoding processes, and an output image controller 108 for constructing an output display. In this way, it is possible to perform parallel decoding processes of video streams efficiently with limited resources and eliminate processing delay which would occur due to temporary concentration of temporally varying an amount of processing when a plurality of video streams are subjected to reproducing operations in parallel.
