Video coding including auxiliary information for performing and tracking successive processing steps like editing, splicing, fingerprinting

摘要

To generate coded data including additional coding information, non-compressed image data is first supplied. The number of predetermined units (i.e.: frame) of the non-compressed image data is counted. Coding is performed on the supplied non-compressed image data. Information for specifying a coding device stored in a memory and the unit count number are obtained and are combined to generate additional coding information. The additional coding information is added to coded data and the resulting data is then output. It is predetermined whether the supply of the non-compressed image data is completed. If not, the number of frames is counted and the following steps are repeated. If the supply of the non-compressed image data is completed, the process is completed.
