Abstract: A communication relay includes a port configured to be connected to a terminal device, a memory that stores instructions, and a processor that executes the instructions. The instructions cause the processor to perform: referring to a communication rate at the port; measuring the communication rate; and calculating a sampling value indicating a communication state based on the measured communication rate.

Abstract: A communication relay apparatus includes a plurality of LAN ports configured to receive LAN cables respectively, at least one switch configured to switch to any one of a plurality of states, and an aggregator configured to specify a combination of two or more of the plurality of LAN ports in accordance with a state that is designated in the at least one switch, and conduct redundancy or expansion of a communication bandwidth with respect to a communication performed through the LAN cables that are received in the specified LAN ports.

Abstract: As an electronic tone is generated in response to performing operation, the electronic tone is picked up by microphones corresponding to left and right channels, and picked-up sound signals thus generated by the microphones are then subjected to signal processing, such as reverberation impartment utilizing acoustic conditions of the interior of a room. Picked-up sound signals having undergone such signal processing are audibly reproduced via rear speakers. Then, once an automatic adjustment instruction is given from a user, measuring tones are reproduced stereophonically, and contents of the signal processing of the individual channels are adjusted on the basis of measured results of picked-up sound signals generated by the microphones picking up the reproduced measuring tones.
