Description

METHOOD, SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM FOR PROVIDING PERSONAL VIDEO RECORDING SERVICE BASED ON NETWORK}

The present invention relates to a method, a system and a computer readable recording medium for providing a network-based personal recording service. More specifically, by recording a broadcast content in a storage space on a network with a personal video storage device and playing it when a user requests it, the user can watch the broadcast at a desired time, at a desired place, and in a desired manner. At the same time, the present invention relates to a method, a system, and a computer-readable recording medium for providing a network-based personal recording service that can solve a copyright infringement problem.

In recent years, with the development of broadcast communication technology, users can acquire various information through not only a personal computer (PC) connected to the Internet, but also a TV receiver, a mobile phone, and the like. In particular, the scope of use of TV, which was only one-way information transmission device, has been greatly expanded. In particular, in recent years, with the spread of cable TV, satellite TV, and IPTV (Internet Protocol TeleVision), broadcasters have been able to provide various services to users through TV, and users have to use personal computers. Similarly, a TV receiver can be used to receive broadcast content or additional information associated with it.

In addition, as the types of broadcast contents and the types of content providers are diversified, it becomes difficult for a user to provide all the broadcast contents desired by the user in real time, so that the broadcast contents desired by the user are recorded and the broadcast contents are provided when the user wants to watch. There is a need for a recording service for broadcast content to be received.

However, in order to provide a recording service for the broadcast content, a predetermined storage space for storing the broadcast content is required. Therefore, a huge budget is required for a separate storage device for each user, and individual storage is required. The disadvantage is the high cost of maintenance of the device. In addition, copyrighted content or broadcasters may be infringed due to the possibility of illegal redistribution of broadcast contents stored on the hard disk of each user's set-top box and the lack of proper measures to prevent such redistribution. There was a limit that it is difficult to expect their response.

It is an object of the present invention to solve all the problems described above.

Another object of the present invention is to provide a network-based personal recording service for allowing a user to watch a desired broadcast through various terminal devices at a desired time and place.

In addition, the present invention is to allocate the remote storage space existing on the network for each user, so that the broadcast content requested by the user can be stored in the remote storage space allocated to the user, the user can watch later By providing broadcast content through a streaming service when requested, it aims to protect copyright by preventing unauthorized distribution of the broadcast content.

Representative configuration of the present invention for achieving the above object is as follows.

According to an aspect of the present invention, there is provided a method for providing a network-based personal recording service, the method comprising: (a) receiving a recording request signal for at least one broadcast content from a user terminal device; Encoding at least one broadcast content according to a predetermined format, and encrypting the at least one broadcast content requested by reference to the identification information of the user who made the recording request, and (c) the encoding and the encryption. And storing the broadcast content in a remote storage space allocated for the user who made the recording request.

According to another aspect of the present invention, there is provided a system for providing a network-based personal recording service, the recording request receiving unit for receiving a recording request signal for at least one broadcast content from a user terminal device, the recording request at least one broadcast An encoding unit for encoding content according to a predetermined format, an encryption unit for encrypting the at least one broadcast request requested with reference to identification information of the user who has made the recording request, and the encoding and the encrypted broadcast content. Provided is a system including a broadcast content storage unit for storing the recording request in a remote storage space allocated to a user.

In addition, there is provided another method, system, and computer readable recording medium for recording a computer program for carrying out the method for implementing the present invention.

According to the present invention, since the user can be provided with the broadcast content using various terminal devices without being constrained in time or place, the effect of improving the efficiency of providing the broadcast content and the user's satisfaction is achieved.

In addition, according to the present invention, since the broadcast content requested by the user can be stored in a remote storage space allocated to the user, the time and cost required for the user to purchase or maintain an individual storage device can be reduced. It is possible to prevent the unauthorized redistribution of the recorded broadcast content, thereby preventing the copyright infringement from occurring.
