A method and apparatus is set forth for accelerating the total acoustic echo cancellation convergence time in a microphone array full-duplex conferencing system with beamformer. The invention is based on sequentially switching the beamformer to untrained sectors during periods of far-end speech activity and performing real-time cancellation of far-end echo signals from the near-end signals to consecutively adapt and store filter coefficients for the echo canceller corresponding to each sector.

To provide an image processing apparatus that can reduce power consumption as compared to a conventional case by energizing required minimum devices at an appropriate timing depending on contents of a request received from an external apparatus through a communicating medium during a power-saving state, if a data processing request is received from the external apparatus through a NIC during a sleep mode, an MPU of the NIC and an MPU of each controlling unit control automatic changeover switches, which switch energization states of sub-power sources, to control energization of each function block based on contents of the data processing request and the state of the own apparatus. When switching the function blocks from a “non-energized state” to an “energized state”, a hierarchical energization controlling process is performed to switch the functional blocks with hierarchical relationships to the “energized state” in the order from higher to lower blocks.

The invention provides a device, method and program for mornitoring CATV transmission path. Gate switches can switch an amount of attenuation, and are set in a distributed manner on distribution lines and a trunk on subscribers' house side in a CATV transmission path having a tree structure with an optical node that follows a headend being taken as a starting point. An upstream-transmission-quality monitoring unit monitors an S / N ratio of an upstream signal obtained from an upstream port having the headend connected thereto to detect a decrease in upstream transmission quality based on a degree of decrease and a continuation state of an S / N ratio. When the upstream-transmission-quality monitoring unit detects a decrease in upstream transmission quality, a noise-generation-source searching unit performs a sequential switching control over the amount of attenuation at the gate switches provided on the CATV transmission path from upstream to downstream to search for a source of generation of upstream ingress noise.
