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.

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.

A control information decoding section (102) decodes sets of control information contained in a stream. Further, a random access information analyzing section (101) carries out analysis of locations of random access points of media items contained in the stream, on the basis of the sets of control information. Still further, a management information generating section (103) generates management information for managing a plurality of random access points contained in the stream, on the basis of decoded versions of the sets of control information, which has been obtained by the control information decoding section (102), and the locations of the random access points obtained by the analysis performed by the random access information analyzing section (101). Then, the management information thus generated and the stream are recorded onto a storage medium (104). This makes it possible to quickly start playback in performing random-access playback of a stream into which control signals are inserted at regular intervals.

A data recording device of the invention has: a reception state acquisition processing section (21) for creating a reception state value on whether the reception state of a broadcast content is good or poor; a recording data creation process section (22) for creating recording data from them; and a recording control processing section (20) for comparing the reception state with a threshold value when there is a change in the reception state value, and controlling whether to pass the recording data to the recording data creation processing section (22). A data reproduction device of the invention has: a formatting analysis processing section for analyzing a format of the recorded data read from a recording medium and extracting the reception state value and the broadcast content; a reproduction control processing section for controlling reproduction of the received data according to the reception state value; a decoding section for decoding the content according to the reproduction control; and an output section for outputting the decoded content. This provides the data recording device capable of reducing a memory amount required for recording the content and the data reproduction device capable of reducing unpleasant feelings felt by a user upon reproduction of a content.

An image quality/rate control portion 106 confirms whether a predictive code amount Ci is a target code amount Rt or less. When the predictive code amount Ci is the target code amount Rt or less, the predictive code amount Ci is output to a base layer coding portion 101. Then, a switch 108 is turned off. When the predictive code amount Ci exceeds the target code amount Rt, the target code amount Rt is output to the base layer coding portion 101. Then, the switch 108 is turned on and (predictive code amount Ci−target code amount Rt) is output to an enhancement layer coding portion 103. A buffer 104 stores coded data of the base layer coding portion 101 and the enhancement layer coding portion 103. In this manner, while performing fixed bit rate coding using a single transmission path, image quality of a moving image is made constant so as to prevent deterioration of image quality.

An apparatus and a method for machining a gear shape whereby when a gear is machined with a form tool, sludge is easily excluded and an accurate gear shape is provided. A method for machining an accurate gear shape whereby with a workpiece chucked, postprocess steps such as grinding and lapping are performed for consistent machining from material to completion of the gear shape, thereby removing a handling error caused by re-chucking the workpiece. A form tool supplied to a holder that can be rotated and slid in the Z direction by an automatic tool changer and a workpiece held by a chuck mounted on a side table that can be driven in the X and Y directions are synchronously rotated at a mesh assumed position under the control of a control section. Cut amount control is applied between both axes of the workpiece and the form tool and the workpiece is machined with the form tool. Form tools are supplied one after another by the automatic tool changer. With the workpiece chucked, mesh synchronous move of the form tool and the workpiece is performed and postprocess steps of machining are performed.
