The present invention is aimed at making it possible to assess a radio wave intensity distribution widely covering areas and frequencies, and thereby making it possible to assess a distribution, widely covering areas and frequencies, of the quality of a communication function provided by a radio wave.

A radio wave intensity distribution assessment apparatus according to the present invention comprises: a radio wave station position detection unit that detects a position of a radio wave station on the basis of a geographic image having position information and of an image of the radio wave station; a radio wave station information integration unit that outputs radio wave station information based on the position of the radio wave station and radio wave station license information on the radio wave station; and a radio wave intensity distribution estimation unit that estimates and outputs a radio wave intensity distribution within a designated range on the basis of the radio wave station information and geographic information on the surroundings of the radio wave station.

An example apparatus to monitor media that is presented via a mobile device includes: an application monitor to determine when media presentation software is being executed by the mobile device; and a metering information collector to collect at least one of a signature or a code of the media presented by the media presentation software based on the media presentation software being executed by the mobile device.

A plurality of auxiliary transmitters associated with at least one main transmitter, transmitting broadcast area wide programming for their respective broadcast areas, wherein a mechanism enables switching on transmission of localized auxiliary information content by at least one of the plurality of auxiliary transmitters, wherein the at least one of plurality of auxiliary transmitters transmits localized auxiliary information content on a single frequency network transmission frequency, and wherein the localized auxiliary information content includes a data item that enables retrieval of promotional information from a remote server, when the data item is analyzed by a software application.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. A receiver, to automatically switch from presenting a service on a first frequency to a second frequency such as when a mobile receiver is moving through a boundary region between two broadcasters, can consider not just signal strength and error rates of two frequencies carrying the same service to select which frequency to tune to, but also relative location and direction of motion of the receiver with respect to each broadcaster.

A method for broadcasting a data stream in at least one broadcast network. The method includes inserting, into the data stream, at least one identifier associated with at least one broadcast area of the broadcast network used to broadcast the data stream. The at least one identifier is transmitted in signalling information of an application to be executed by at least one receiver of the data stream.

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. A receiver uses relative location and direction of motion of the receiver with respect to each broadcaster to determine which tuner/demodulator(s) to use to present a service and which to use to scan for services.

A remote management system includes: a facility information receiver that receives facility information representing a facility within a space; a facility information storage that stores the facility information; a use information receiver that receives use information representing a facility to be operated during a use period of the space among facilities represented by the facility information; a use information storage that stores the use information; a relay that relays communication between the facility within the space and an outside of the space; and a facility controller that controls the facility to operate or not to operate via the relay, based on the facility information and the use information.
