    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.

    摘要: Each of a plurality of pages of video data are shuffled, each of the pages being composed of a plurality of blocks of data, using a data memory having a memory capacity of one page. The one page data memory temporarily stores data in a current page. A data address generator generates an address of the data memory so that the data in the current page are written into the data memory in a first sequence and the written data are read out from the data memory in a second sequence which is different from the first sequence to thereby shuffle the data in the current page. The data address generator generates the address such that data in a block in the current page is read from a portion of the data memory indicated by the address generated by the data address generator, and such that data in a block in a next page is written into the portion of the data memory indicated by the address generated by the data address generator.
