46) REGISTER B SET

LD/CD

 

 

 

Function:

Changes the current setting of Register B. (Squelch Control)

Format:

Integer

R B

 

 

 

Explanation:

Attributes concerning the squelch switch for video and audio are set

 

in Register B. The squelch switch is normally controlled

 

 

automatically in accordance with the operating mode of the player.

 

In the modes where pictures and sound are not clearly reproduced,

 

the squelch switch prevents the noise from being displayed or heard.

 

(eg. During scanning on LaserDiscs, audio is squelched.)

 

 

By rewriting the contents of the Register B, it is possible to make

 

the squelch switch invalid. In this state, the video and audio

 

signals are continually output.

 

 

 

 

The initial value is 0.

 

 

 

 

It must be noted that these signals may contain noise

 

 

components which may adversely affect equipment connected to

 

the output of the player. Therefore, the operation must be fully

 

understood before this function is used.
