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.

A system and method for controlling a mobile device at a headend includes the mobile device communicating a request for content to the headend. The headend requests geographic coordinate location data from the mobile device and, when geographic coordinate data is available, determines a first geographic region associated with the mobile device in response to the geographic coordinate location data. When geographic coordinate data is not available from the mobile device, the headend extracts an IP address from the request and determines a second geographic region based on the IP address and a confidence level. When the confidence level is below a threshold, the headend determines a third geographic region based on subscriber data for the mobile device. The headend controls the mobile device in response to one of the first geographic region, the second geographic region and the third geographic region.

The present technology relates to a reception apparatus, a reception method, a transmission apparatus, and a transmission method that make it possible to do a promotion for a non-subscriber to a pay broadcast service more flexibly. The reception apparatus receives broadcast content that is provided as a pay broadcast service and transmitted in a scrambled manner, acquires a subscription check application for checking presence of a subscription to the pay broadcast service depending on information indicating presence of the subscription check application, the information being included in control information including information regarding a structure of the broadcast content, and controls an operation of the subscription check application. The present technology is applicable, for example, to a television receiver capable of receiving a digital broadcast signal.

A management apparatus includes a memory and a processor coupled to the memory. The processor is configured to broadcast an activation request to a plurality of information processing devices having a reception period during which the activation request is received. The reception period occurs in a predetermined cycle. The processor is configured to receive a confirmation response from first information processing devices among the plurality of information processing devices. The first information processing devices receive the activation request. The processor is configured to issue an activation instruction to a predetermined number of second information processing devices among the first information processing devices. The activation instruction instructs to activate the second information processing devices. The processor is configured to issue, to the first information processing devices other than the second information processing devices, an activation prohibition instruction to prohibit activation.
