The present technology relates to a receiving device, a receiving method, a transmission device, a transmission method, and a program, which allow an application program to be created in an optimum production environment. An AIT acquisition and analysis unit acquires mapping information in which a first directory structure, to be used in the case of transmitting a resource constituting an application program by a first transmission system, and a second directory structure, to be used in the case of transmitting a resource constituting the application program by a second transmission system, are associated with each other. When an application program including a resource created in accordance with the first directory structure is transmitted by the second transmission system, a carousel processing unit allows the resource created in accordance with the first directory structure to correspond to the second directory structure using the mapping information to thereby acquire the application program transmitted by the second transmission system. The present technology is applicable to television receiver, for example.

Spectrum harvesting methods and spectrum harvesters implementing such spectrum harvesting methods are disclosed. In some embodiments, multiple spectrum harvesters may be configured to scan a frequency band of interest in a distributed and staggered manner. The results obtained by the spectrum harvesters may be shared with each other according to a round-robin scheme. Distributed scanning and round-robin sharing techniques configured in accordance with the inventive concepts disclosed herein may allow the spectrum harvesters to jointly function as a continuous spectrum scanner capable of providing near real time spectrum harvesting.

A process for allowing a Concurrent Multi-Netting (CMN-4) equipped Link 16 terminal to enter an active network. After an initial entry command is entered at the terminal at a given current time at the terminal, a number of time slots are identified in which multiple receivers at the terminal have an opportunity to detect an initial entry message (IEM) after the given current time. Each of the receivers is set to detect an IEM during a different one of the identified time slots. When an IEM is first detected by one of the receivers, the current time at the terminal is reset based on the time slot in which the IEM was detected.

An internet of things (IOT) system includes an IOT server and multiple IOT devices and a voice-controlled device connected to the IOT server and the multiple IOT devices. The voice-controlled device receives a voice-controlled message of environmental sound information through a voice control interface, and broadcasts the voice-controlled message to neighboring IOT devices to drive a corresponding IOT device according to the voice-controlled message. When failing to recognize the voice-controlled message, the voice control interface uploads the voice-controlled message to a cloud server for query through the IOT server, and broadcasts a result of the query returned from the cloud server. A way of chain broadcasting is employed by the voice-controlled device to drive selected IOT device or receive returned information so as to enhance operational convenience in using IOT devices.
