Can be seen through. That is,
When the user inputs a personal identification number, a broadcast program designation, and the like to the user terminal 1, the user terminal 1 sends a distribution request including these (personal identification number, broadcast program designation, etc.) to the communication line 3. The investigating unit 7 of the user-owned TV video distribution device 2 corresponding to the user terminal 1 receives the TV video signal distribution request from the user terminal 1 via the communication line 3 and receives the password included in the distribution request. The number is collated with the personal identification number stored in advance in the television image distribution device 2 when the television image distribution device 2 is installed, and the distribution request is validated when these personal identification numbers match. The distribution unit 8 is the research unit 7
When the result of the check is valid, the TV video signal specified by the designation of the broadcast program included in the distribution request is searched from the TV video signal stored in the storage unit 6, and the searched TV video signal is distributed to this TV video distribution. Distribution is performed via the communication line 3 to the user terminal 1 corresponding to the device 2 (for example, the address of the user terminal 1 corresponding to this device is stored when the television image distribution device 2 is set). When the television image signal designated by the designation of the broadcast program is being accumulated in the accumulation unit 6, that is, when it is currently being broadcast, the communication line 3 is connected to the user terminal 1 in a compressed format of the accumulated television image signal. Deliver in real time via. When the television video signal designated by the designation of the broadcast program is not yet broadcast, this is notified to the user terminal 1 via the communication line 3. The user terminal 1 receives from the communication line 3 a notification indicating that the television image signal has been distributed or that the television image signal has not been broadcast, and displays it on the screen.

[0023]

As described above, according to the television image delivery apparatus and the television image delivery system of the present invention, the user terminal sends out the delivery request of the television image signal including the image signal and the audio signal to the communication line. Then, the television image distribution device receives a television image signal from the television broadcast transmission station, receives a request to deliver the television image signal from a predetermined user terminal corresponding to the own television image distribution device through the communication line, and receives the television image signal in advance. A television video signal corresponding to a delivery request is delivered to a predetermined user terminal via a communication line, and the user terminal receives the delivered television video signal from the communication line and displays it. In response to the distribution request sent from the TV video distribution device, the specified TV video signal is received via the communication line and displayed. When you want to see the Levi program (television video signal), it is possible to see this TV program in anywhere. Also, existing communication lines are used to deliver TV programs (TV video signals), but receiving and storing this TV program is similar to recording a video signal on a VCR. It is a television image distribution device owned by the user corresponding to the user terminal and is for personal use, so that the television program can be watched without violating the copyright of the broadcast program.
