Abstract
Region or field data corresponding to digital contents contained in a stream is embedded in the header field of the stream transmitted from a data output system. A data processing system controls grant/denial of partial processing in correspondence with the contents in the stream data on the basis of the region or field data embedded in the header field of the data packet in place of limiting the entire stream. Hence, the contents that each receiving system can deal with can be flexibly controlled without requiring any control for changing the stream to be transmitted in accordance with the branch structure of a title.
Claims3
A stream data processing system for receiving and processing stream data, comprising:
- means for embedding field data in a header field of a data packet to form stream data wherein the field data indicates a classification of the data packet that is socially or educationally determined;
- means for setting desired field data;
- and
- limiting means for controlling grant and denial processing of the stream data in units of the data packet based on a comparison between the desired field data and the field data contained in the data packet.
