It was At this time, as requested by the user,
It was not possible to extend the rental period of the data already borrowed.

Further, it is impossible to add the number of reproducible times by limiting the number of reproducible times even within the borrowing period, or by requesting the user when the number of reproducible times is exceeded. It was

The present invention has been made in order to solve the above-mentioned problems, and even when the system is constructed by using the existing broadcasting equipment such as satellite broadcasting, CATV, text broadcasting, etc. The purpose of the present invention is to realize an electronic rental system in which the viewing time can be freely selected, and viewing operations such as rewinding, pausing, and fast-forwarding are possible.

Further, by deciding the borrowing period, the video data and the audio data are borrowed for a certain period and repeatedly reproduced during the borrowing period, or when the user requests,
The purpose is to realize an electronic rental system that can extend the rental period of already borrowed data.

Further, if the service provider requires it, it is possible to limit the number of times that the rented-out video data and audio data can be reproduced, or to add the number of times that the user can reproduce, if desired. The purpose is to realize a possible electronic rental system.

Further, an electronic rental system can be realized in which the video data and the audio data reproduced during the borrowing period can be duplicated by recording and recording, and the reproduction can be prevented even after the borrowing period has passed. The purpose is to do.
