Abstract

Abstract A multispeed reproducing control apparatus of a video disk player for playing CLV disks (1) causes a portion of the information carrying tracks to be scanned. A track jump operation is performed, this process being repeated to reproduce the recorded video at a selected multiple of the standard reproducing rate. To maintain proper image display at the selected reproducing speed, the track jump interval and the number of tracks jumped on each track jump command are controlled in accordance with the radial position of the pickup head (2).

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 130 words
A multispeed reproducing control apparatus of a video disk player for playing a CLV disk (1) at a constant linear velocity, comprising: position detecting means (8) for producing a position signal representing the position of an information detecting point (2) in the radial direction of the CLV disk (1); jump command generating means (7a) for generating a jump command signal at a timing changed in accordance with the position signal; and, drive signal generating means (7a) for supplying a drive signal having a magnitude according to the number of tracks to be jumped, determined in accordance with a designated multispeed and the position signal, to a section (10) for controlling the position of the information detecting point (2) of the video disk player in response to the jump command signal.
Claim 2
Dependent Claim 130 words
A multispeed reproducing control apparatus of a video disk player for playing a CLV disk (1) at a constant linear velocity, comprising: position detecting means (8) for producing a position signal representing the position of an information detecting point (2) in the radial direction of the CLV disk (1); jump command generating means (7a) for generating a jump command signal at a timing changed in accordance with the position signal; and, drive signal generating means (7a) for supplying a drive signal having a magnitude according to the number of tracks to be jumped, determined in accordance with a designated multispeed and the position signal, to a section (10) for controlling the position of the information detecting point (2) of the video disk player in response to the jump command signal.
Claim 3
Dependent Claim 58 words
Apparatus according to claim 1, wherein the jump command generating means (7a) comprises a counter for counting a timing pulse generated at a fixed period, and means for generating the jump command signal each time a counted value of the counter reaches one of a plurality of predetermined jump count values variable in accordance with the position signal.
Claim 4
Dependent Claim 57 words
Apparatus according to claim 1, wherein the jump command generating means (7a) comprises a counter for counting a timing pulse generated at an interval variable in accordance with the position signal, and means for generating the jump command signal each time a counted value of the counter reaches one of a plurality of predetermined jump count values.
