摘要： A video encoding device includes a re-encoding picture type judgment unit which judges whether a picture is to be taken as a reference picture or not in a subsequent re-encoding process, and a refresh unit sets no refreshed unit area in the picture when the picture is judged by the re-encoding picture type judgment unit to be taken as a non-reference picture in the subsequent re-encoding process, but sets, when the picture is judged to be taken as a reference picture, a refreshed unit area in the picture to be taken as a reference picture so as to include an area corresponding to a refreshed unit area which should have been set in a picture to be taken as a non-reference picture.

摘要： In order to attenuate vibration which tends to be transmitted from a power unit to a vehicle passenger during the idling mode of engine operation, ERF filled engine mounts are arranged so that when neither of two orifice passages are restricted by impressing a voltage on ERF viscosity control electrodes included therein, the frequency at which the dynamic spring constant exhibits a minimum value is the same as the frequency at which the vibration transmission phase maximizes while one of the two orifice passages is restricted by the application of a voltage on the set of electrodes disposed therein. Rapid cyclic control of the dynamic spring constant and the vibration transmission phase for each mount used to support a power unit is carried out. This enables a desirable compromise in the control of the two different parameters.
