FINALIZE:
This process makes a DVD-R disc recorded on this DVD video camera/recorder playable on a DVD
player, etc. that conforms to 8 cm DVD-R: No further recording can be made on a finalized DVD-R disc.
HOWLING:
This phenomenon occurs as follows: When the DVD video camera/recorder is connected to a device,
such as TV, the audio input to the microphone of DVD video camera/recorder is amplified and output
from the speakers of TV, and the signal is again input to the microphone: This is repeated to form an
endless loop of audio signal, and the signal is amplified up to the audio output amplitude limit of the
device. Howling can be prevented by changing the positional relationship between the DVD video
camera/recorder and TV, or by turning down the volume on TV.
INFRARED SENSOR:
This sensor is used to adjust the white balance.
LASER PICKUP BLOCK:
This block emits laser beam to a disc, and then collects the laser beam reflected from the disc to convert
it to an electric signal. The block consists of a laser, lens, receiving element, etc.
LINEAR PCM:
Audio recording format similar to MPEG audio layer 2: However, linear PCM does not compress an
audio signal, but instead samples it and converts it to a digital signal to be recorded. Therefore, the
amount of data used is larger than that of MPEG audio layer 2.
MultiMediaCard:
This is a standard of memory card developed in 1997. The card is 32 mm long x 24 mm wide x 1.4 mm
thick, and has 7 pins. It can be inserted into SD memory card slot and used.
