If the system determines that the amplitude of the YFM signal is High
relative to the AFM, then the conventional filtering system will be em-
ployed. The result would be a standard resolution recording.
A conventional system uses the fixed band stop filter to separate the sig-
nals again in playback. The result is a standard resolution playback sig-
nal.
A dynamic band stop filter is used in the XR system. This filter senses the
presence of the relatively low YFM signal inside the AFM band and ad-
justs its filtering accordingly. The result is a YFM signal with extended
resolution.
Laserlink
Laserlink is a feature in Sony camcorders that sends Sircs information
and audio/video signals via infrared emitter to a Sony TV and an optional
IR receiver. There is no noticeable loss of picture quality between Laserlink
and composite video.
In order for the system to work you need the IFT-R10A infrared wireless
receiver or a new Sony Laserlink equipped VHS machine. This is an
optional accessory and is only necessary if you want to use the Laserlink
function. This accessory contains a composite video output that is con-
nected to your video display’s input. It also contains separate left and
right audio outputs that are connected to the component that will be pro-
ducing your sound.
In order to use the system, you simply point the camera in the direction of
the IR receiver and the TV and press PLAY. Sircs signals are then sent
from the camcorders infrared emitters. The first of these signals is the TV
ON command and the second is the selection of the video input source.
You can select Video 1, Video 2 and Video 3 or OFF using the camera’s
menu. You may also select whether or not you would like the Power ON
command sent by using the camera’s menu. Once the Sircs commands
have been sent, audio and video information is transmitted from the
camera’s infrared emitters to the infrared receiver. The receiver decodes
the infrared signals and outputs them so that the picture can be seen and
the sound heard.
