Information processing apparatus and method

An information processing method comprising:

• generating a control file managing image encoded data for each of a plurality of sub-pictures into which an entire picture is divided and which is then encoded and including region-related information related to a region in the entire picture corresponding to the sub-picture, as information different from arrangement information for each of picture regions, the control file being used for controlling distribution of the image encoded data.

An information processing apparatus comprising:

• a file acquiring section configured to acquire a control file managing image encoded data for each of a plurality of sub-pictures into which an entire picture is divided and which is then encoded and including region-related information related to a region in the entire picture corresponding to the sub-picture, as information different from arrangement information for each of picture regions, the control file being used for controlling distribution of the image encoded data;
• and
• an image processing section configured to select a stream of the image encoded data on a basis of the region-related information included in the control file acquired by the file acquiring section.
