A video signal generation apparatus for decoding a bit stream to generate a video signal, includes: a writing unit configured to write a flag value indicating whether a decoding target block has been coded by intra-coding or inter-coding in a specified bit position on one bit plane having a size the same as that of the decoding target block, to write information indicating a coding division form of the decoding target block in a specified common area on the one bit plane, and to write the coding information in a specified switch interpretation area on the one bit plane according to a data format conforming to the intra-coding if the decoding target block has been coded by intra-coding, and to write the coding information in the specified switch interpretation area according to a data format conforming to the inter-coding if the decoding target block has been coded by inter-coding; and a generation unit configured to generate a video signal by superimposing the one bit plane on a decoded image of the decoding target block.

In order to actualize a power feeding control apparatus and a charging system that are capable of efficiently charging plural storage batteries using a load-capacity controlled power source, the power feeding control apparatusis configured so that a changeover control of the feeding of the alternating-current voltage to each charger will be performed monitoring the magnitude of the alternating current flowing in each of the plural chargersto, therewith, the power feeding control apparatus performs the feeding changeover control comprising the steps of: feeding only to a predetermined one particular charger at the early stage of the start of charging, in which stage a large charging current flows into a storage battery; monitoring inflow current of the predetermined one particular charger; and switching power feeding to another charger to start feeding thereto when the inflow current reduces to the charging saturation current (a current still flowing even at the fully charged state).

To make such an ordinary hub as works on the power fed through a power adapter connected to a commercial power supply be capable of maintaining its hub-function without interruption even when a commercial power supply failure occurs. The ordinary hub is connected to a line securement power supply unitthat is power-fed from a POE-compliant power-feeding hubthrough a communication cable, wherein a means for producing a power for an ordinary hub using a power fed through said communication cableso as to feed produced power to an ordinary hub; and a storage battery, which stores power while power-receiving, to be used as the power source for producing a power for said ordinary hub when a power failure, are provided in said line securement power supply unit

A method of obtaining a motion vector in moving images is based on evaluation of computational results of searches made by matching a target template and a group of pixel blocks each having a same size as the target template. The steps include: 1) searching in a wide area and obtaining a reference vector to indicate an overall image movement; 2) searching in narrow areas centered about the reference vector for all templates in the target image, and obtaining a displacement vector for each template in relation to the reference vector; and 3) summing the reference vector and the displacement vector for each template, and assigning a computed result as a motion vector in each template.
