摘要： Red, blue and green color difference signals are supplied to the bases of first, second and third transistors amplifying the tri-color signals of red, blue and green, and a luminance signal is introduced to the emitter of each transistor through a parallel circuit of two resistors. One of the resistors in each parallel circuit is connected through a switch. The switches are associatively operated so that the on-off operation of the switch connected to the emitter of the first transistor is opposite to that of the switches connected to the emitters of the second and the third transistor. By operating the switches, the amplification degree of the first transistor is increased and simultaneously the amplification degrees of the second and third transistors are decreased, and therefore an image with red emphasized can be obtained with no change in luminance.

摘要： A video disc player having an operational state for holding the disc without rotation when the disc has been inserted into or has been prepared for withdrawal from the player as well as a reproduction state for picking up the signal recorded on the disc when the disc is on the rotating turntable, in which the time of the holding state of the disc is measured and when the holding state of the disc exceeds a predetermined time, the disc is set on the turntable and the turntable continuously rotates until another state instruction is generated, thereby suppressing deformation of the disc.
摘要翻译：一种视频光盘播放器，当光盘已被插入或已准备好从播放器中取出时，具有用于保持光盘而不旋转的操作状态以及当光盘打开时用于拾取记录在光盘上的信号的再现状态测量盘的保持状态的时间的旋转转盘，当盘的保持状态超过预定时间时，将盘设置在转台上，并且转台连续旋转直到产生另一状态指令，从而抑制盘的变形。
