Broadcast transmitting apparatus, receiving apparatus, and broadcast transmitting method, receiving method

Abstract

A broadcast transmitting apparatus stores and manages the material for composing a broadcast program as AV data, creates storing control information showing a process control method when storing this AV data in a broadcast receiving apparatus, and storing management information showing management information during storing, and registers them as reference information and stores and manages, and transmits according to schedule information managing the schedule of the broadcast program. On the other hand, the broadcast receiving apparatus executes an storing control command according to the storing control information, and stores and manages the AV data according to the storing management information. Further, the broadcast transmitting apparatus creates application information from the reference information being stored and managed, and transmits it together with service application for executing broadcast program service. Receiving them, the broadcast receiving apparatus extracts the corresponding AV data from the stored and managed AV data according to the application information, and executes the service application. By such processing, the transmitting apparatus can control the AV data to be stored in the receiving apparatus, and the broadcast program service using it.
