Abstract

PURPOSE: To unnecessitate the registration operation of a user and to enable the program reviewing which does not gives the operational trouble to the user and the viewing of the continuation of the program by issuing a viewing certificate discriminating the program that the user views and inputting the program discrimination information entered in the viewing certificate by the user. CONSTITUTION: When the viewing of a program is terminated, a recording information generation circuit 114 reads program discrimination information from a program information storage circuit 113 and delivers the information to a card issuing device 115. A card issuing device 115 records information for magnetic card recording in a card 130 and issues the card. When a user inserts the card 130 into a card reader 141, the card reader 141 reads magnetic recording information from the card 130 and delivers the information to a recording information reading circuit 142. The recording information reading circuit 142 takes out the program discrimination information from the read magnetic recording information. A program request circuit 143 gives the program transmission request in which the program discriminated by the taken program discrimination information is defined as a viewing object to a program transmitter 120.

Receives a program transmission request and passes it to the transmission management circuit 123. The transmission management circuit 123 performs control for starting to supply the video from the beginning of the program instructed by the program transmission request, to the second terminal 140 after the elapsed time. According to the control, the program transmission circuit 124 transmits the video from the beginning of the program instructed by the program transmission request after the elapsed time.
This is performed toward the second terminal 140.

The second decoder 144 decodes the video and transfers it to the second monitor 145.
The program is displayed on.

FIG. 12 is a block diagram showing the structure of a program viewing system according to an embodiment of the present invention.

At the first terminal 110, the program transmission device 12
The video supplied from 0 is displayed on the first monitor 111. This video is a program stored in the program storage circuit 121 from the program transmission device 120 to the first terminal 110.
And the video is decoded by the first decoder 112. From the first decoder 112, program identification information for identifying the program being displayed is decoded by another route and written in the program information storage circuit 113. The elapsed time from the beginning of the program for the screen being displayed is sequentially output from the first decoder 112.

When the user cancels the viewing of the program and turns off the power of the first terminal 110,
The reproduction position reading circuit 211 acquires the elapsed time from the beginning of the program for the screen being displayed, and the program information storage circuit 11
Write to 3. The recording information generation circuit 114 reads the program identification information and the elapsed time from the program information storage circuit 113, converts it into magnetic card recording information, and the card issuer 11
Pass to 5. The card issuer 115 records the magnetic card recording information on the card 130 and issues it.

Next, the user carries the card 130 to the second terminal 140 and puts the card 1 in the card reader 141.
When the card 30 is inserted, the card reader 141 causes the card 13
The magnetic recording information is read from 0, and the recording information reading circuit 1
Pass it to 42. The recording information reading circuit 142 extracts the program identification information and the elapsed time from the read magnetic recording information.
The program request circuit 143 makes a program transmission request to the program transmission device 120 for viewing after the elapsed time of the program identified by the extracted program identification information.

The request acceptance circuit 122 of the program transmission device 120
Receives a program transmission request and passes it to the transmission management circuit 123. The offset value addition circuit 1211 adds a negative parameter value to the elapsed time designated during the program transmission request.
The transmission management circuit 123 controls to start supplying the video to the second terminal 140 after the correction elapsed time in which the negative parameter value is added from the beginning of the program instructed by the program transmission request. Under the control, the program sending circuit 124 sends the video to the second terminal 140 from the beginning of the program instructed by the program sending request and after the elapsed time.

The second decoder 144 decodes the video and transfers it to the second monitor 145, and the second monitor 145 receives it.
The program is displayed on.
