Recording apparatus and recording system

A recording apparatus for recording data in a recording medium in an MPEG4 file format, wherein MPEG4 data is built in at least a first format in the MPEG4 file format, the recording apparatus comprising:

• a receiving unit configured to receive a second format MPEG4 data including multiplexing information having stored in a MOOF BOX in the MPEG4 file format;
• an interpreting circuit configured to detect whether or not reproduction information for reproducing the first format MPEG4 data from the second format MPEG4 data is stored in a BOX for storing a type of data that is ignored at a time of playing included in the MPEG4 data where the BOX is included in the second format MPEG4 data;
• a first module configured to extract, when the interpreting circuit detects that the reproduction information is stored, BOX data for building the first format MPEG4 data from the reproduction information;
• a second module configured to build the first format MPEG4 data from the second format MPEG4 data by using the BOX data;
• and
• a controller configured to record the first format MPEG4 data including multiplexing information having stored in a MOOV BOX in the MPEG4 file format in the recording medium.

A recording system, comprising:

• a first recording apparatus configured to record video data and audio data in a recording medium in an MPEG4 file format;
• and
• a second recording apparatus configured to store data in a recording medium in the MPEG4 file format, wherein:
• MPEG4 data is built in at least a first format in the MPEG4 file format;
• the first recording apparatus includes:
• a transmitting unit;
• a first MPEG4 file format generating circuit configured to generate first MPEG4 data including multiplexing information of the video data and the audio data stored in a MOOV BOX in the MPEG4 file format;
• a second MPEG4 file format generating circuit configured to:
• store reproduction information required for reproducing the first MPEG4 data from MPEG4 data including the multiplexing information having stored in a MOOF BOX in the MPEG4 file format in the BOX in the MPEG4 file format for storing the type of data that is ignored at the time of playing;
• generate second MPEG4 data including both the MPEG4 data and the BOX for storing type of data that is ignored at a time of playing;
• and
• output the second MPEG4 data to an external apparatus via the transmitting unit;
• and
• a first controller configured to record the MPEG4 data generated by the first MPEG4 file format generating circuit in a recording medium;
• the second recording apparatus includes:
• a receiving unit configured to receive the second format MPEG4 data;
• an interpreting circuit configured to detect whether or not the reproduction information for reproducing the first format MPEG4 data from the second format MPEG4 data is stored in the BOX for storing a type of data that is ignored at a time of playing included in the MPEG4 data where the BOX is included in the second format MPEG4 data;
• a first module configured to extract, when the interpreting circuit detects that the reproduction information is stored, BOX data for building the first format MPEG4 data from the reproduction information;
• a second module configured to build the first format MPEG4 data from the second format MPEG4 data by using the BOX data;
• and
• a second controller configured to record the first format MPEG4 data in a recording medium;
• the first controller of the first recording apparatus is configured to record the first format MPEG4 data in a first recording medium;
• the second module of the second recording apparatus is configured to generate the same data as the first format MPEG4 data from the second format MPEG4 data;
• and
• the second controller of the second recording apparatus is configured to record the first format MPEG4 data generated by the second module in the second recording medium that is different from the first recording medium.
