Abstract: In a “local production for local consumption” network including a backhaul line formed by wireless multi-hop communication between a plurality of base stations, and a plurality of local service servers, communication speed is increased by appropriately selecting communication routes between the user terminals and the local service servers, and the power efficiency of the wireless communication by minimizing the power consumption of the overall system. A network control server collects information regarding the user terminals, the access points, and the local service servers, sets communication routes between the user terminals and the local service servers, groups of the base stations, those of the existing base stations and local service servers that are active so as to optimize a power efficiency of the overall network according to the collected information, and notifies the base stations, the local service servers or the user terminals of route information regarding the communication routes.

Abstract: The voice control device includes a sound source signal input unit, a frequency determination unit, a band controller, a sound image controller, and a voice output unit. The sound source signal input unit inputs a sound source signal of content from a sound source. The frequency determination unit determines a cutoff frequency.

The sound image controller generates a plurality of sound image control signals for controlling sound images of the plurality of speakers, by controlling at least one of a phase and a sound pressure level of the high frequency signal. The voice output unit outputs the low frequency signal to a first speaker, and outputs the plurality of sound image control signals to a second speaker composed of a plurality of speakers.
