A reception apparatus includes a memory configured to store a television receiver application. The reception apparatus further includes processing circuitry configured to display, via a television broadcaster application, a user interface that provides a plurality of services for user selection. The processing circuitry is further configured to receive a user selection of a service from the plurality of displayed services. The processing circuitry is further configured to determine whether the selected service is an Advanced Television Systems Committee (ATSC) 1.0 service. In response to the determination that the selected service is the ATSC 1.0 service, the processing circuitry is further configured to continue execution of the television broadcaster application along with a display of the contents of the selected service.

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.

A matching method of a shared display module is provided and has steps of: receiving, by a mediation platform, a service requirement specification, wherein the service requirement specification has a lease time zone of at least one display module disposed an a building exterior wall; comparing, by the mediation platform, the service requirement specification with at least one service providing specification of a plurality of service providers in the mediation platform; and transmitting, by the mediation platform, at least one compared service providing specification matching with the service requirement specification to a user end of the service requirement specification. The matching method matches a leasable time zone of the display module on the building exterior wall by the mediation platform, so that the display module displays an image or a video demanded by the user end.

A method for emergency communication includes encoding a message for visual display including a message to field and a message from field. The visual display is revealed to a reading device in communication with a broadcast center, which stores the visual display. The messages are decoded and sorted from visual displays at the broadcast center. On an index channel, a time and channel number for when a message body of the message will be broadcast on a message channel is broadcasted. The message body is broadcasted on the message channel.

A system and method for improving the DRM (Digital Radio Mondiale) signal acquisition time stores the demodulated DRM signal and accesses it from memory in order to avoid the additional time taken in waiting for service description channel (SDC) data. The system includes an antenna to receive a DRM signal. A tuner tunes the frequency of receiver to a desired range. An asynchronous sample rate converter (ASRC) converts the sampling rate of the received signal to a demodulator sampling rate. A demodulator demodulates the received signal. A memory stores the demodulated signal for reuse. A channel splitter splits the received signal into a fast access channel (FAC), a service description channel (SDC), and a main service channel (MSC). A channel decoder decodes the channel split data. A middleware and an application parses and processes the data in order to output the processed data.
