摘要： In a digital video signal recording/reproducing apparatus for recording digital VCR video and audio signals by using a rotary cylinder, for a video signal with a frame frequency fN of 30 Hz or 29.97 Hz, the rotating frequency of the cylinder is set to 2.5 times fN. On the other hand, for a signal with a frame frequency fP of 25 Hz, the rotating frequency of the cylinder is set to 3.0 times fP. As a result, as long as the cylinder diameters are identical, the relative speed of the tape and the head is the same for video signals of either frame frequency fN or fP.

摘要： A random number generation device comprises a pseudo random number generation section that is capable of outputting random numbers of a plurality of different pseudo random number sequences, a physical random number generation section for generating physical random numbers, and a switching section for switching the pseudo random number sequence of random numbers output by the pseudo random number generation section on the basis of the physical random numbers generated by the physical random number generation section, where the output of the pseudo random number generation section is used as output random numbers. Since the plurality of different pseudo random number sequences are switched and output according to the physical random numbers, predictability of the random numbers can be reduced in comparison to a conventional random number generation device that uses only pseudo random numbers. Furthermore, since the physical random numbers are not directly used as the output random numbers, any adverse effect on the predictability of the output random numbers is substantially reduced compared with a conventional device even if the physical random number generating means are somehow manipulated from the outside.

摘要： The video signal input is converted to high-speed reproduction data by a high-speed reproduction data encoder 1. The video signal input is converted to high-speed reproduction data by a formatter 2, which formats the high-speed reproduction data so that the same data is recorded to n tracks. After the recorded data is input to an error correction encoder 3, it is decoded by a decoder 4 and recorded by a recording head 5 to the magnetic tape 6. During reproduction, the recorded data is reproduced by reproduction head 7 from the magnetic tape 6, and decoded by decoder 8. The decoded data is then error corrected by an error correction decoder 9, and then input to a deformatter 10. The deformatter 10 separates the normal reproduction data from the high-speed reproduction data, and separately outputs both data types. During normal reproduction, the normal reproduction data is output by a switch 13; the high-speed reproduction data is decoded to video data by a high-speed reproduction data decoder during high speed reproduction, and output.
