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.

The present invention relates to an image display device and an operation method thereof. The image display device, according to one embodiment of the present invention, comprises: a display; a network interface unit for carrying out communication with an external server via a network; a broadcast receiving unit for receiving a broadcast signal; a storage unit; and a control unit. The control unit: receives a personalized advertisement signal including advertisement content via at least one among the network interface unit and the broadcast receiving unit; outputs the advertisement content through the full area of the display; receives a broadcast signal including broadcast content via at least one among the network interface unit and the broadcast receiving unit; calculates the ending time of the advertisement content; determines whether the starting time of the broadcast content is before the ending time of the advertisement content; and if the starting time of the broadcast content is before the ending time of the advertisement content, may output the broadcast content through a first area in the full area of the display and output the advertisement content through a second area in the full area of the display, starting from the starting time of the broadcast content. Other various embodiments are possible.

A wireless distribution system (WDS) is configured for transmitting a downlink signal or for receiving an uplink signal. A computing device configured to serve as a client device to the WDS includes a memory; a multiple applications processor in communication with the memory and configured to execute one or more mobile applications; and a wireless service processor in communication with the multi applications processor for communicating via a corresponding wireless service with the WDS. The multi applications processor is configured to execute an instance of a data service to establish a connection with the WDS for a specified application process utilizing the wireless service to provide at least one datum on the WDS. In the method, an instance of a data service is executed to establish a connection with a WDS for a specified application process utilizing a wireless service to provide at least one datum on the WDS.

A vehicle reception apparatus can receive a broadcast signal through a receiver, perform data communication for receiving and displaying a broadcast service without transmission loss, and maximize memory efficiently by controlling an encoder and an interface in a vehicle. For example, the vehicle reception apparatus includes a receiver configured to receive a broadcast signal, a demodulator configured to extracting a baseband (BB) frame including service data and a BB frame size based on the received broadcast signal, an encoder configured to receive, from the demodulator, the extracted BB frame and the extracted BB frame size, and store the extracted BB frame in a buffer, and an interface configured to receive, from the encoder, the stored BB frame and the BB frame size.
