The present invention provides a technique that makes it possible to output, with a simple operation of a user, information which is relevant to an object displayed by a display device. A display device () includes: NFC antennas (); a managing section () for managing, for each of the NFC antennas, antenna identification information and object location information such that the antenna identification information and the object location information are associated with each other; an NFC communication control section () for obtaining proximity information; and an information output section () for outputting relevant information which is associated with the object location information.

Information output system, control method, and control program

The present disclosure facilitates the establishment of near field communication with a mobile terminal while also preventing malfunctions and an increase in burden of maintenance. A display apparatus () includes: at least one antenna () for carrying out near field communication with a mobile terminal (), the at least one antenna being provided so as to positionally overlap with a display section (). In a case where the mobile terminal comes into proximity to the display section, the display section is caused to display a guide for bringing the mobile terminal in proximity to at least one of the at least one antenna.

Display apparatus, image display system, and information providing server

A predetermined process is executed in accordance with a state of a detection target which has been detected through short range communication with the detection target. In a case where a control device () has determined that a location of an NFC tag () detected by a display device () had changed, the control device () causes the display device () to transmit predetermined information to the communication terminal () via an NFC antenna ().

Control device utilizing short range communication to detect movement of an object and display information associated with the detected movement

A source devicetransmits streaming data. In a packet receiverof a sync device, statistical data acquirercalculates statistical data such as one-way delay time, packet loss ratio, reception rate and the like from the received streaming data and transmits it to the source device. The statistical information received by source deviceis extracted by a packet receiverand input to a channel band estimator. The channel band estimatorgives encoderinstructions to provide optimal encoding based on the transmission delay. Upon this, the transmission delay is calculated by assuming the minimum value of the communication delay from the start of transmission as zero. Control is performed by determining the delay time and packet loss ratio in data transmission and considering, based on these, the channel quality and bandwidth margin, so as to provide the optimal transmission bit rate or encoding rate.
