Abstract
There is provided a recording device for generating and coding metadata, the recording device including a metadata describing part for describing the metadata; and a coding part for coding the metadata described in the metadata describing part in a binary format, and generating coded data; wherein the metadata describing part describes alternative information for embedding alternative data to the coded data when data is not present for a non-essential item in the metadata; and the coding part performs coding with the alternative data embedded when the alternative information is described.
Claims6
A recording device for generating and coding metadata, the recording device comprising:
- a metadata describing part for describing the metadata;
- and
- a coding part for coding the metadata described in the metadata describing part in a binary format, and generating coded data;
- wherein
- the metadata describing part describes alternative information for embedding alternative data to the coded data when data is not present for a non-essential item in the metadata;
- and
- the coding part performs coding with the alternative data embedded when the alternative information is described.
A recording method for generating and coding metadata, the recording method comprising the steps of:
- describing the metadata;
- and
- coding the metadata described in the metadata describing step in a binary format, and generating coded data;
- wherein
- in the metadata describing step, alternative information for embedding alternative data to the coded data is described when data is not present for a non-essential item in the metadata;
- and
- in the coding step, coding is performed with the alternative data embedded when the alternative information is described.
A computer program for generating and coding metadata, the computer program comprising the steps of:
- describing the metadata;
- and
- coding the metadata described in the metadata describing step in a binary format, and generating coded data;
- wherein
- in the metadata generating step, alternative information for embedding alternative data to the coded data is described when data is not present for a non-essential item in the metadata;
- and
- in the coding step, coding is performed with the alternative data embedded when the alternative information is described.
