A polycrystalline silicon producing method includes: the first process and the second process. In the first process, a surface temperature is maintained at a predetermined range by adjusting the current value to the silicon seed rod, and the raw material gas is supplied while maintaining a supply amount of chlorosilanes per square millimeter of the surface of the rod in a predetermined range until a temperature of the center portion of the rod reaches a predetermined temperature lower than the melting point of the polycrystalline silicon, and in the second process, a previously determined current value is set corresponding to a rod diameter and the supply amount of the raw material gas per square millimeter of the surface of the rod is decreased to maintain the surface temperature and the temperature of the center portion of the rod at predetermined ranges, respectively.

Any one of three settings is provided in accordance with total time Tx of data to be written to a DVD: a first setting in which a maximum value of image bit rate (first value B1) and a maximum value of audio bit rate (second value B2) are used; a second setting in which a first value of image bit rate and a third value B3 of audio bit rate are used; and a third setting in which a fourth value of image bit rate determined on the basis of line 152 and the third value B3 of audio bit rate are used. The present invention is applicable to information processing apparatuses for recording the data recorded to a digital cassette video tape to a DVD.
摘要:
The present invention relates to an information processing apparatus and a program for executing a sequence of processing operations including the recording of video data recorded to a first recording medium in a first format to a second recording medium in a second format without user's manual intervention. If the information processing apparatus determines that the recording time of a frame just reproduced by a predetermined reproduction device is earlier than the recording time of a frame reproduced by said reproduction device immediately before the above-mentioned frame (step S89) or an unrecorded area has been reproduced by the reproduction device for more than a predetermined period of time (step S90), the information processing apparatus stops the acquisition of the data recorded to a digital video tape reproduced by the reproduction device (step S92), thereby stopping the reproduction of the digital video tape (step S93). The present invention is applicable to information processing apparatus for recording data from digital cassette video tape to DVD, for example.
