A portable information terminal includes a controller configured to control a communication interface to transmit a charging permission response to a broadcast receiving apparatus in response to a charging permission request data transmitted when a broadcasting program that a user of the broadcast receiving apparatus desires to view contains an asset that requires charging. The charging permission response is allowed to be transmitted when positional information indicates that the portable information terminal is positioned inside of a predetermined positional range and apparatus identification information in the charging permission request data, by which the broadcast receiving apparatus is allowed to be identified, coincides with apparatus identification information stored in a memory. The controller controls the communication interface to transmit a charging denial response to the broadcast receiving apparatus when the positional information indicates that the portable information terminal is positioned outside of the predetermined positional range.

A configuration in which a reception device can determine whether or not data reception via a network is permitted on the basis of signaling data is implemented. A class identifier indicating a group of reception devices or users that are permitted to perform data reception via a network is recorded in signaling data transmitted from a transmission device to a reception device. A reception device determines whether or not a class identifier is identical to a class identifier set to a reception device or a user and performs data reception via a network when the class identifiers are identical to each other. A URL base pattern applied to data reception via a broadcast wave or a network is recorded in signaling data, and a reception device performs data acquisition to which the URL base pattern is applied.

A digital broadcast receiving apparatus capable of executing a function with a higher added value is provided. A broadcast receiving apparatus configured to receive broadcasting data on digital broadcasting is used. The broadcast receiving apparatus includes: a broadcast receiving unit configured to receive broadcasting data containing coded video data regarding a broadcasting program of the digital broadcasting and control information for the broadcasting program; a video decoding unit configured to decode the coded video data received by the broadcast receiving unit to reproduce program video information; a display unit configured to display the program video information reproduced by the video decoding unit; a communication unit configured to transmit viewing permission request data to a predetermined portable information terminal in a case where a broadcasting program that a user of the broadcast receiving apparatus desires to view is a program on which viewing limit is to be imposed, the communication unit being configured to receive response data from the portable information terminal, the response data responding to the viewing permission request data; an authentication information storing unit configured to store terminal identification information and authentication information, the predetermined portable information terminal being allowed to be identified by the terminal identification information; and a control unit. The control unit is configured to: control the video decoding unit or the display unit so as not to limit viewing of the broadcasting program that the user of the broadcast receiving apparatus desires to view in a case where the response data received by the communication unit indicates a display permission response and both of terminal identification information and authentication information contained in the display permission response respectively coincide with the terminal identification information and the authentication information stored in the authentication information storing unit; and control the video decoding unit or the display unit so as to limit the viewing of the broadcasting program that the user of the broadcast receiving apparatus desires to view in a case where any of the terminal identification information and the authentication information contained in the display permission response does not coincide with corresponding one of the terminal identification information and the authentication information stored in the authentication information storing unit even though the response data received by the communication unit indicates the display permission response.

The present invention relates to an arrangement or a device for transmission and verification of signals in audio visual radio transmitters and receivers, such as TV receivers, set-top boxes, mobile handsets, etc. The receiver may be configured to receive a number of signal units within a frequency range. An identifying unit is configured to identify the signal units. A comparator unit configured to make possible for at least a portion of the signal units to be forwarded or at least partially be blocked with respect to the receiver. A verification unit, which includes a memory configured to store at least a number of signal units, verify that each forwarded signal units that pass the arrangement is being registered by means of a specific signal in a register unit.

Provided are an apparatus and a method for processing conditional access system (CAS)-based content. A method of operating a broadcast receiving apparatus includes: receiving a broadcast stream that includes content encrypted based on a CAS; extracting, from the received broadcast stream, CAS information for decrypting the encrypted content; receiving an entitlement control message (ECM) having a preset format based on the CAS information generated in a different format for each broadcasting business operator; and displaying the content decrypted based on the ECM.

A method is described for the locationally selective transmission of a signal by radio. Both a transmitter and a receiver are synchronized to the same time reference. The receiver receiving and demodulating, at a time that is one of the specified times of the time reference, a signal transmitted by the transmitter, if the receiver has received the signal at a time that is one of the specified times. The method includes the transmitter determining a receive location within a receive zone to which it wishes to transmit the signal in selective fashion, a position in the receive zone being a function of a position of the transmitter and a signal runtime. The method also includes the transmitter transmitting the signal; and the receiver, which is situated inside the receive zone, receives and demodulates the signal.
