Abstract

A contents recording system and a contents recording method reducing a time taken for recording and editing of video content and other video contents and enabling editing of the video contents with a high reliability. An optical disk device for recording video content and a computer are connected via a network. The computer is supplied with clip data of the video and low resolution proxy AV data from the optical disk device, streaming reproduces them as live video and, at the same time, introduces essence marks as meta-data to any positions of the proxy AV data, and describes them in a meta-data file. When a communication abnormality occurs between the optical disk device and the computer, the clip data is notified to the computer again.

Claims

1. A contents recording system having a first processing part transmitting video contents and a second processing part receiving the video contents, wherein

the first processing part is provided with

a recording part recording video contents in parts of a start of recording to an end of recording and managing the video contents by unique contents IDs and

a transmitting part starting transmission to the second processing part in the order of recording the video contents before the recording part ends the recording of one video contents,

the second processing part is provided with

a receiving part receiving the video contents from the first processing part together with the contents IDS,

a display part displaying the received video contents, and

an index information processing part introducing to a desired position of the video contents displayed on the display part index information serving as an index of that position of the video and recording that position and index information linked together, wherein

the second processing part receives the contents IDS again when a communication abnormality occurs between said transmitting part and said receiving part conditional on the communication being restored to normal and the recording part being in the middle of recording being detected.

2. A contents recording system as set forth in claim 1, wherein

said first processing part divides the video contents into a plurality of video contents for each predetermined period and transmits it in packet parts given consecutive packet IDS and

said second processing part records video contents in the same file before and after occurrence of a communication abnormality conditional on the first contents ID received before the occurrence of the communication abnormality and the second contents ID received after the occurrence of the communication abnormality matching and the packet IDS of the received video contents being consecutive before and after occurrence of the communication abnormality.

3. A contents recording system as set forth in claim 2, wherein said second processing part inserts a stuffing video of a period corresponding to a difference of packet IDs before and after occurrence of a communication abnormality conditional on the first and second contents IDS matching and the packet IDB of the received video contents not being consecutive before and after occurrence of the communication abnormality.

4. A contents recording system as set forth in claim 2, wherein said second processing part records in different files the video contents received before and after occurrence of a communication abnormality conditional on the first and second contents IDs not matching.

5. A contents recording system as set forth in claim 4, wherein said second processing part inserts a stuffing video of a period corresponding to the packet ID of the video contents received after the occurrence of a communication abnormality.

6. A contents recording method performed between a first processing system and a second processing system, including

having the first processing system

start recording of video contents linked with unique contents IDS and

start transmission of the video contents to the second processing system in the order of recording before ending the recording of the video contents and

having the second processing system

receive the video contents together with the corresponding contents IDs,

display the received video contents,

introduce to a desired position of the video contents to be displayed index information serving as an index of that position of the video,

detect whether the first processing system is in the middle of recording the video contents, and

receive the contents ID again when a communication abnormality occurs between said transmitting part and said receiving part conditional on the communication being restored to normal and the recording part being in the middle of recording being detected.

7. A contents processing system for processing video contents transmitted from a contents transmitting system, comprising:

a receiving part receiving video contents transmitted from a transmitting part of said contents transmitting system together with unique contents IDs for managing the video contents,

a detecting part detecting if the recording part of said contents transmitting part is in the middle of recording video contents,

an index information processing part introducing to a desired position of said video contents displayed on a display part an index information serving as an index of that position of the video and recording the positions and index information linked together, and

a control part controlling so as to receive the contents ID again when a communication abnormality occurs between said transmitting part and said receiving part conditional on the communication being restored to normal and the recording part being in the middle of recording being detected.
