Title: Positioning control method for optical disk device
Inventor: KATO KIKUJI
IPC: G11B7/085
Filed: 1988-06-24
Abstract: PURPOSE:To position a light beam on a prescribed track at high speed and with high accuracy by detecting the relative displacement of a 1st tracking actuator to a positioner via a position detector and correcting the track signal detection error of an erasing beam which is caused by the relative displacement. CONSTITUTION:The track control accuracy is improved for the recording and reproducing beams requiring the higher position accuracy than an erasing beam 40 since a positioner 65 is made follow the movement of the reproducing beam 42. At the same time, the track control accuracy is improved for the beam 40 by correcting the track signal detection error which is caused by a fact that the reflected light of the beam 40 sent from a disk moves on a photodetector during the follow-up to the track eccentricity and during a high-speed movement of the positioner 65. As a result, a single positioner 65 can move those beams 40-42 in the radius direction of a disk medium and position them on the same track at the high speed and with high accuracy.

Title: Video encoder
Inventor: MIZUTA TAKASHI
IPC: H04N19/132
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a video encoder that can apply high efficiency coding processing to a video signal in a shorter processing delay time without causing missing-frame of a reproduced video image at a receiver side. SOLUTION: A timing control section 104 outputs a data read start signal (RS) to a data read section 105 in timing at a point of time when a data storage section 102 stores data by a predetermined initial storage amount based on a coding start signal (SS) and data storage amount information (FD). Thus, the data storage amount in the data storage section 102 is not zero but has a finite offset in excess of zero at all times. Simultaneously since a video coding section 101 receives a feedback input of the data storage amount information (FD) and conducts coding processing at a constant average bit rate, the data storage section 102 always stores video coded data (ED) by a required minimum data storage amount. The high efficiency coding can be applied to the video signal in a shorter processing delay time without causing missing-frame of a reproduced video image at a receiver side.
