Data processing system having data reproduction independent of data processing

An apparatus for writing and reproducing data comprising:

• processing means for processing inputted data and producing processed data;
• storage means for storing said processed data in a storage medium;
• decompression means for decompressing processed data stored in said storage medium and producing decompressed data;
• reproducing means for reproducing said decompressed data while new input data is being processed by said processing means;
• and
• control means for controlling said storage means to store said new input data processed by said processing means in said storage medium during reproducing of said decompressed data by said reproducing means,
• wherein said processing means comprises a converting means for converting a format of said inputted data, and
• wherein said inputted data is compressed in a predetermined compression format and said converting means comprises second decompression means for decompressing said inputted compressed data and a compression means for compressing said decompressed data in another compression format.

An apparatus for writing and reproducing data comprising:

• processing means for processing inputted data and producing processed data;
• storage means for storing said processed data in a storage medium;
• decompression means for decompressing processed data stored in said storage medium and producing decompressed data;
• reproducing means for reproducing said decompressed data while new input data is being processed by said processing means;
• control means for controlling said storage means to store said new input data processed by said processing means in said storage medium during reproducing of said decompressed data by said reproducing means;
• and
• reading out means for reading out data stored in said storage medium therefrom at a predetermined reading out data rate,
• wherein said control means controls said storage means to write said processed data at a faster writing data rate than said predetermined reading out data rate.

An apparatus for reproducing data comprising:

• converting means for converting inputted data of a first compression format into converted data of a second compression format;
• outputting means for outputting said converted data converted by said converting means;
• reproducing means for reproducing data corresponding to said converted data;
• and
• control means for controlling said outputting means to output said converted data concurrently with the reproducing of said data by said reproducing means,
• wherein said converting means comprises decompression means for decompressing said inputted compression data and compression means for compressing said decompressed data into said data of said second compression format.

An apparatus for reproducing data comprising:

• converting means for converting inputted data of a first compression format into converted data of a second compression format:
• outputting means for outputting said converted data converted by said converting means;
• reproducing means for reproducing data corresponding to said converted data;
• control means for controlling said outputting means to output said converted data concurrently with the reproducing of said data by said reproducing means;
• and
• reading out means for reading out compression data stored in a storage medium,
• wherein said converting means converts said read out compression data of said first compression format to said converted data of said second compression format.

An apparatus for reproducing data comprising:

• processing means for processing inputted data according to a predetermined requirement;
• outputting means for outputting data generated by the processing means as output data;
• reproducing means for reproducing data generated by the processing means;
• and
• control means for controlling said outputting means to output said output data during reproducing of the data by said reproducing means, wherein the reproduced data can be different data than the output data produced by said outputting means.

A method for writing and reproducing data comprising:
