The present invention relates to an information providing system, an information providing apparatus and a method thereof, and an information processing apparatus and a method thereof suppressing unauthorized use of the video contents. A stream contents server 3 issues permission information to a data contents server 10. The data contents server 10 provides the data contents to which the permission information is added to a TV receiver 7. A data broadcast engine 73 extracts identification information from the stream contents provided by the stream contents provider 1, and feeds it to the stream contents provider 1 together with the permission information extracted from the data contents. Based on the permission information and the identification information, the stream contents provider 1 judges whether the reference to the stream contents by the data contents be permitted, and transmits the result of judgement to the digital TV receiver 7. The invention can be adapted to a digital broadcast system. |
