DATA PROCESSING SYSTEM, DATA PROCESSING METHOD, AND DATA PROCESSOR

摘要

Based on the detailed reproduction control information defining the reproduction control state of data to be transmitted, the CPU 12 of the data transmission apparatus creates a simplified reproduction control information roughly defining the reproduction control state of the data, stores the simplified reproduction control information of the data in the packet header of a data packet carrying the data, stores the detailed reproduction control information in the data, and transmits the simplified reproduction control information and the detailed reproduction control information as well as the data to the data receiving apparatus 20 through the transmission channel 30 from the input-output interface 16. The CPU 22 of the data receiving apparatus 20 analyses the reproduction control state of the data contained in the data packet based on the simplified reproduction information and the detailed reproduction information contained in the data packet, and controls the reproduction of the data by the action of the media access part 26 according to the analysis result.
