Abstract: A multimedia optical disc for recording main video data which is composed of sets of frame data that is processed beforehand to enable display at an aspect ratio specified out of a plurality of aspect ratios. The disc has a stream area storing streams made up of the main video data and a plurality of sets of sub-picture data, with each set of sub-picture data including a set of tel-op data and a set of coordinate information showing a display position of the set of tel-op data. The disc also includes a control area storing a plurality of pairings of a set of display mode information and a set of sub-picture indicating information. Each set of display mode information shows a species of display method according to which the frame data is to be processed for a case when the frame data decoded from the main video data is displayed at one of the plurality of aspect ratios.

Abstract: A multimedia optical disc which includes a data region for storing a plurality of objects which include video data, audio data and sub-picture data, wherein the data region is composed of a plurality of small regions, wherein each object is stored in consecutive small regions and wherein each small region includes a first subregion for storing video data of a certain reproduction period, a plurality of second subregions which each store audio data, wherein audio data stored in different second subregions express different reproduction audio to each other and each set of audio data is data to be reproduced at a same time as the video data in a first subregion, a plurality of third subregions which each store sub-picture data, wherein sub-picture data stored in different third subregions express different images to each other and each set of sub-picture data is data to be reproduced at a same time as the video data in the first subregion and a fourth subregion for storing control information, wherein each set o

Abstract: A multimedia optical disc on which a variety of types of video titles are recorded and which enables a reproduction apparatus to instantly distinguish whether emulated AV functions may be performed for any of the titles. The multimedia optical disc includes a manager area which stores playback type information corresponding to the management information for each video title, with the playback type information including a first flag showing whether the present video title is expressed using one or a plurality of sets of route information and a second flag showing whether a title is expressed using any branch information.

Abstract: A multimedia optical disc including data area and index area is provided. The data area includes objects each of which includes video data. The index area includes sub-areas. Each sub-area includes addresses of objects selected from the objects in the data area, a flag indicating a random reproduction of the objects selected, and a number of repeats of the random reproduction.

Abstract: A visually effective image switching apparatus includes a frame memory unit for storing image data for one picture and a decoder for expanding a compressed image data and for outputting the expanded image data. Also included is a graphic memory controller for writing the expanded image data outputted from the decoder directly in the frame memory unit. An I/O access unit is also provided for selecting whether the expanded image data is to be written or not written at the present address of the frame memory. A local bus unit is also provided for transferring the expanded image data to the graphic memory controller. The timing of the decoder, the graphic memory controller and the I/O access unit are controlled by a CPU unit.

Abstract: A parallel traveling control system detects distances to a guide rail provided on a road surface of a traveling lane or set close thereto, and drives the brake pressures in such a direction that the distances between the vehicle and the guide rail coincide with set values. Additionally, the system detects the rotation of the steering wheel, designates automatic parallel traveling in which the brake pressures are driven to correct the vehicle's direction, and terminates automatic parallel traveling when the steering wheel is rotated more than a predetermined angle.

Abstract: A hydraulic suspension control device includes a real yaw-rate detector means for detecting angular velocity around a vertical axis of a vehicle body and a vehicle speed detector for detecting the vehicle speed and a wheel angular detector for detecting the front wheel angle and a target yaw-rate calculation for calculating the target yaw-rate using signal values from the vehicle speed detector and the wheel angle detector. The electric control device includes a driving circuit which is set to receive a signal of deviation between the real yaw-rate and the target yaw-rate and controls an actuator having a pressure valve and a hydraulic cylinder both of which are controlled by the electric control device so that an instability yawing in vehicle movement such as rear wheel side slips can be prevented during the vehicle turning movement.
