REGISTER B SET
Function:
Changes the current setting of Register B. (Squelch Control)
Format:
Integer
R B
Explanation:
In Register B, attributes concerning the squelch switch for video
and audio are set. 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. (i.e. During scanning, 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 always going out.
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.
Execution:
* Avoid the video squelch during searching.
