摘要:
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). A control designation value for the peripheral devices and producer's preference information indicative of an acceptable error range for the control designation value are inputted from the audio-visual environment control data input unit (104), as audio-visual environment control data for one or more peripheral devices in an audio-visual environmental space where video data and/or audio data are reproduced, and the control designation value and the preference information are transmitted together with the video data and/or the audio data.
摘要:
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. A lighting dimming data generation unit generates driving control data for driving and controlling an actual lighting device (32) in accordance with identification information, lighting control data, and arrangement information of the lighting device (32) in an actual audio-visual environment space, wherein the arrangement information is acquired from a lighting arrangement information memory unit (25).
摘要:
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.
摘要:
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).
摘要:
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.
