Abstract:
PURPOSE: A broadcast signal receiving device for controlling a broadcast program using a signature of program information and a method thereof are provided to control the use of a broadcast program using a signature included in program information. CONSTITUTION: A communication unit(210) receives a broadcast signal. An extracting unit(220) extracts a broadcast program and program information from the received broadcast signal. A determining unit(230) generates a signature for verification to check whether the program information is changed from the extracted program information. The determining unit compares the signature of the extracted program information with the signature for the verification. The determining unit determines the validity of the program information.

PURPOSE: A system and a method for authenticating the personal-use of contents through portable media are provided to use the contents without a restriction by confirming a registered domain key of a user. CONSTITUTION: A packager(230) depackages contents into a package key, package key information, and encrypted contents. An access controller extracts the domain information from the contents which is provided from the package key information. The access controller(240) extracts the reproduction information from the contents which is provided from the package key in the event the domain information and domain authentication information are identical. A controller(220) controls the operation of the packager and the access controller. The encrypted contents are provided to the controller and the controller provides the encrypted contents to a player(260).
Abstract:
PURPOSE: An apparatus and a method for transmitting/receiving a digital broadcast are provided to repetitively play stored advertisement contents after storing advertisement contents which are transmitted in non real time, thereby removing a need of repetitively transmitting the advertisement contents. CONSTITUTION: A broadcast receiver(101) receives advertisement contents and information about a play time of the advertisement contents. A contents storing unit(103) stores the received advertisement contents. A broadcasting controller(105) controls the play time of the stored advertisement contents according to the information for the play time of the advertisement contents. The broadcast receiver receives broadcast contents which are transmitted in real time and played. The broadcast controller controls the broadcast contents to be stored in the contents storing unit.
Abstract:
PURPOSE: An apparatus and a method for protecting broadcasting contents are provided to prevent indiscreet distribution of recorded broadcasting contents using a broadcasting receiver, thereby safely protecting the broadcasting contents. CONSTITUTION: A controller(102) controls setup of a channel to be recorded. The controller controls recording time and file conversion. A program input unit receives a broadcasting signal. The program input unit tunes the set channel to output the broadcasting contents. A virtual file module(107) changes the outputted broadcasting content into a virtual file. A storage unit(108) stores the converted virtual file.
Abstract:
PURPOSE: An apparatus and a method for the conversion of digital broadcasting contents based on program protection information are provided to control the conversion of a broadcasting program by using a protection signal inserted into a broadcasting program, thereby preventing the illegal redistribution of the broadcasting program, including protection information. CONSTITUTION: A program transform control device demultiplexes a received broadcasting program into broadcasting data and a protection signal(202). In addition, the program transform control device encodes the broadcasting data based on the distribution condition of the program protection signal when recording is required(218). Furthermore, the control device records the encoded broadcasting program data(216,220).

Abstract:
Disclosed is a method for house reservation of digital B channel booking within a narrow band ISDN exchanger. The method comprises 6 steps. In the first step(301, 302), when a process block(DSSC) for house reservation of digital B channel booking is requested for service, the house reservation service of digital B channel booking is checked whether issued or not. In the second step(303 to the extent of 305), the number of houses in a member line is checked if the house reservation service is issued. In the third step(306 to the extent of 309), the house reservation is performed if the number of houses is below 4. In the fourth step(401, 402), a terminal identification value is compared to a stored value when the member request to retrieve his house. In the fifth step(403 to the extent of 405), the retrieve is rejected when the terminal identification is different as a stored value, and check the state of B channel when the terminal identification is same as a stored value. In the sixth sep(406 to the extent of 409), the house reservation is continued if the B channel is not a break period, and the house retrieve is performed if the B channel is a break period. Thereby, the house reservation service can be effectively applied to the narrow band ISDN exchanger.
Abstract:
To provide an internal direct number service processing method in the switchboard for narrow band integrated services digital network(N-ISDN) to directly call extension subscriber of private interface device from the outside without a help of exchanger. The internal direct number service processing method includes the first step that checks whether the associated subscriber is a private switchboard connection subscriber, the second step that checks numbering form of the subscriber after proceeding the first step, the third step that proceeds valid number after the second step and the fourth step that transmits the analyzed number to the private switchboard. Thereby, it is possible to provide the internal direct number service to directly call extension subscriber of private interface device from the outside without a help of exchanger.
