Recorder and transmitter

A recorder comprising:

• judgement means for receiving first digital data, and judging whether the first digital data is recordable;
• data conversion means for converting the first digital data into recordable second digital data when the judgement means judges that the first digital data is unrecordable;
• switching means for receiving the first and second digital data, and outputting the first digital data when the judgement means judges that the first digital data is recordable, while outputting the second digital data when the judgement means judges that the first digital data is unrecordable;
• and
• data recording means for recording the digital data outputted from the switching means on a recording medium.

A recorder comprising:

• judgement means for receiving first digital data, and judging whether the first digital data is reproducible after recording;
• data conversion means for converting the first digital data into second digital data that is reproducible after recording, when the judgement means judges that the first digital data is unreproducible after recording;
• switching means for receiving the first and second digital data, and outputting the first digital data when the judgement means judges that the first digital data is reproducible, while outputting the second digital data when the judgement means judges that the first digital data is unreproducible;
• and
• data recording means for recording the digital data outputted from the switching means on a recording medium.

A transmitter comprising:

• system control means for making an inquiry about whether digital data to be output is recordable by a recorder to which the digital data is transmitted, or whether the digital data is reproducible after recording;
• data transmission means for outputting the digital data when it is judged that the digital data is recordable or reproducible after recording by the recorder, on the basis of the result of the inquiry from the system control means;
• decoding means for decoding the digital data into a first analog signal, when it is judged that the digital data is unrecordable or unreproducible after recording by the recorder, on the basis of the result of the inquiry from the system control means;
• and
• format conversion means for converting the first analog signal into a second analog signal of a data format that is recordable by the recorder or reproducible after recording;
• wherein, said decoding means outputs the first analog signal or said format conversion means outputs the second analog signal, when it is judged that the digital data is unrecordable or unreproducible after recording by the recorder, on the basis of the result of the inquiry from the system control means.

A transmitter comprising:

• system control means for making an inquiry about a recordable data format, to a recorder to which first digital data is to be output;
• data conversion means for converting the first digital data into second digital data of a recordable data format, when it is judged that the digital data is unrecordable by the recorder, on the basis of the result of the inquiry from the system control means;
• and
• data transmission means for receiving the first and second digital data, and outputting the first digital data when it is judged that the first digital data is recordable by the recorder on the basis of the result of the inquiry from the system control means, while outputting the second digital data when it is judged that the digital data is unrecordable by the recorder on the basis of the result of the inquiry.

A transmitter comprising:

• system control means for making an inquiry about a data format that is reproducible after recording, to a recorder to which first digital data is to be output;
• data conversion means for converting the first digital data into second digital data of a data format that is reproducible after recording by the recorder, when it is judged that the digital data is unreproducible after recording, on the basis of the result of the inquiry from the system control means;
• and
• data transmission means for receiving the first and second digital data, and outputting the first digital data when it is judged that the first digital data is reproducible after recording by the recorder on the basis of the result of the inquiry from the system control means, while outputting the second digital data when it is judged that the digital data is unreproducible after recording by the recorder on the basis of the result of the inquiry.

A recorder comprising:

• demodulation means for demodulating digital-modulated stream data to first digital data;
• judgement means for receiving the first digital data, and judging whether the first digital data is recordable;
• data conversion means for converting the digital data into second digital data of a recordable data format, when the judgement means judges that the first digital data is unrecordable;
• switching means for receiving the first and second digital data, and outputting the first digital data when the judgement means judges that the first digital data is unrecordable, while outputting the second digital data when the judgement means judges that the digital data is unrecordable;
• and
• data recording means for recording the digital data outputted from the switching means, on a recording medium.
