摘要： A system for personal Internet protocol (IP) broadcasting to which a personal digital rights management (DRM) is applied, and a method thereof are provided. The system for personal IP broadcasting includes: a personal broadcasting transmission unit generating content, storing the content, applying personal DRM encryption to the content, and transmitting the content; a personal broadcasting reception unit receiving the transmitted content, DRM-decoding the content based on a personal DRM certificate corresponding to the content, and reproducing the content; a channel management unit allocating a channel through which the personal broadcasting transmission unit transmits broadcasting, then managing the channel, and transmitting information of a predetermined broadcasting transmission unit requested by the personal broadcasting reception unit; and an authentication server unit verifying validity of each of the personal broadcasting transmission unit and the personal broadcasting reception unit, and issuing and managing the personal DRM certificate. According to the system and method, DRM is applied to the content authored and broadcast by an individual person, thereby enabling the person to claim digital rights. Accordingly, illegal copying of the personal broadcasting content can be prevented and only authenticated users can use the service, thereby preventing broadcasting of inappropriate content or illegal use of the service by an unauthorized user.

摘要： An interactive advertisement system and a method thereof are provided. The interactive advertisement system includes an advertiser server, a local advertisement server, and a service receiver. The advertiser server requests registration of advertisement information by setting advertisement ID including target service areas and provides services in response to an order of available services corresponding to the advertisement information. The local advertisement server stores and registers the advertisement information including the advertisement ID corresponding to the registration request of the advertiser server, multicasts the registered advertisement information with the advertisement ID through an IP network, and transmits information related to a service request to the advertiser server. The service receiver extracts advertisement information providing a corresponding service from the received advertisement information, outputs the extracted information through a user interface, requesting the local advertisement server to order the input service, and receives the corresponding service from the advertiser server.

摘要： A rigid inflatable boat has a structure to position and protect an inflatable tube without having to separate the tube from a boat body. The rigid inflatable boat may include a rubber tube that is attached to each side of a boat body. A folding panel includes one hinged end on each lower side of the boat body and another end including a hook for coupling with a fastener formed on a top portion of the boat body. The rubber tube is connected to an inner surface of the folding panel and a side portion of the boat body by a connection mechanism. The connection mechanism is configured to connect the tube to an inner surface of the folding panel and to the side of the boat body including a pair of guide plates and a pair of insertion bars. The guide plates have one side attached to the inner surface of the moveable plate and the boat body and another side formed with guide grooves disposed longitudinally along the length of boat body. The insertion bars are wrapped with protective fabric and attached to an outer surface of the tube and configured to be inserted longitudinally into the guide grooves.
