Abstract

A recording and reproducing apparatus is installed on a network through which communication with a terminal device is enabled. The recording and reproducing apparatus includes: a recording reservation section that receives a recording reservation request for video data from the terminal device via the network; a communication section that receives the video data which is distributed to the terminal device by using at least one of multicast, broadcast, and unicast; a video recording section that records the received video data based on the recording reservation request; and a video distribution section that distributes the recorded video data to a terminal device that has made a reproduction request for the relevant video data via the network.

Claims

1. A recording and reproducing apparatus installed on a network through which communication with a terminal device is enabled, comprising:

a recording reservation section that receives a recording reservation request for video data from the terminal device via the network;

a communication section that receives the video data which is distributed to the terminal device by using at least one of multicast, broadcast, and unicast;

a video recording section that records the ceived video data based on the recording reservation request; and

a video distribution section that distributes the recorded video data to a terminal device that has made a reproduction request for the relevant video data via the network.

2. The recording and reproducing apparatus according to claim 1, wherein

the video recording section records all the received video data irrespective of presence/absence of the recording reservation request for the video data, and

the video distribution section distributes the recorded video data to a terminal device that has previously made the recording reservation request for the relevant video data.

3. The recording and reproducing apparatus according to claim 1, wherein

the video distribution section transcodes the recorded video data to suit the performance of one or both of the terminal device as a distribution destination and network.

4. The recording and reproducing apparatus according to claim 1, further comprising

a deletion section that receives a deletion request for the recorded video data from the terminal device and deletes the relevant video data.

5. The recording and reproducing apparatus according to claim 1, wherein

the video distribution section counts, for each user of the terminal device, the number of times of reception of the reproduction request for the video data so as to restrict for each user the number of times of distribution of the recorded video data to the terminal device.

6. The recording and reproducing apparatus according to claim 1, further comprising

a deletion section that deletes one or both of the recorded video data and reproduced video data after elapse of a given period of time.

7. The recording and reproducing apparatus according to claim 1, wherein

the video distribution section records stop position of the video data in the case where the reproduction of the video data is stopped halfway during distribution of the video data and starts distribution of the video data from the recorded stop position in the next distribution time of the video data.

14. A video distribution system comprising:

the recording and reproducing apparatus as claimed in claim 1, and

a distribution apparatus that distributes the video data to the terminal device via the network.

15. The video distribution system according to claim 14, wherein

the terminal device is a mobile phone.

8. An operating method of a recording and reproducing apparatus installed on a network through which communication with a terminal device is enabled, comprising:

receiving a recording reservation request for video data from the terminal device via the network;

receiving the video data which is distributed to the terminal device by using at least one of multicast, broadcast, and unicast;

recording the received video data based on the recording reservation request; and

distributing the recorded video data to a terminal device that has made a reproduction request for the relevant video data via the network.

9. The operating method according to claim 8, wherein

at the time of recording of the video data, all the received video data are recorded irrespective of presence/absence of the recording reservation request for the video data, and

the recorded video data is distributed to a terminal device that has previously made the recording reservation request for the relevant video data.

10. The operating method according to claim 8, wherein

in the case where a deletion request for the recorded video data is received from the terminal device, the relevant video data is deleted.
