Realtime MPEG4 streaming capability ideal for live webcasts
Just attach the KA-DV300U network pack to the base
of the GY-DV301E/GY-DV300E, install the PCMCIA
card, and the camcorder is ready for connection to
the Internet via a personal computer. LAN
connection can be via LAN cable or wireless RF LAN
card. As the GY-DV301E/GY-DV300E captures
images, it automatically generates MPEG4 files that
are sent to the Internet in real time. Viewers can see
those streams in real time simply by accessing the
specified IP address on their PC. Ideal for any type
Basic streaming system
With the KA-DV300U network pack installed on the GY-DV301E/GY-DV300E and a
PCMCIA card fitted inside the pack, the camcorder can connect to a PC via a
wired/wireless LAN. Installing the "Streamproducer" software in the PC allows up to
four GY-DV301E/GY-DV300Es to be connected and switched via the PC.
Create a publishing point for distribution.
Images and sound captured with the GY-DV301E/GY-DV300Es can be streamed as
MPEG4 files via the PCMCIA card to the PC. The MPEG4 files are then processed
by Streamproducer and made available for viewing on the Internet.
When viewers access the publishing point IP address, they can play back the
MPEG4 files with the Media Player on their PC. Streams of up to 15 fps (352 x 288)
are assured.
Powerful 3-CCD imaging, 12-bit ADC, 12-bit DSP and
14x zoom lens combine to give superior performance
3-CCD prism camera for high quality picture
To ensure the best possible image quality, the GY-DV301E/
GY-DV300E incorporates three 1/3" CCDs each of 470,000
pixels (440,000 effective). Each CCD attaches to highly
advanced circuitry which virtually eliminates vertical smear when shooting
bright lights in a dark room. Lag and image burn are also reduced to
indiscernible levels, while high sensitivity (F11 at 2000 lux) assures creative
flexibility and simplifies lighting requirements.
Newly developed 12-bit ADC* and 12-bit DSP**
The 12-bit ADC directly inputs to the DSP, thus
eliminating any signal degradation otherwise arising
from the analogue pre-gain and pre-knee circuits. In
addition, JVC's new DSP with advanced 12-bit video
processing brings out all the natural details, eliminates noise, and gives
good gamma response and so reproduces clear detail from dark areas.
*ADC: Analogue Digital Converter **DSP: Digital Signal Processor
400% dynamic range
An ultra-smooth gamma curve, calculated with a true log scale algorithm,
produces a dynamic range of 400%, thus giving totally accurate
reproduction of fine details and subtle colours right across the picture,
including any shadowed or highlighted areas.
14x zoom lens
Both auto and manual control of focus and iris are available. The handle
zoom speed can be adjusted and the large diameter focus ring ensures
smooth, accurate focusing. An optical image stabiliser (inner focus) helps
stabilise images, especially zoomed-in close-ups.
LOLUX 2.65 lux (100% video out)
When activated, the LOLUX mode increases sensitivity
with almost zero increase in noise. LOLUX increases the
gain by 16x (+24 dB) so you can capture high
quality video footage with excellent colour
balance in low-light conditions.

of live event — weddings, concerts, conferences,
and even news reports —, the GY-DV301E/
GY-DV300E sends your images around the world
instantly. Economical and easy to set up, the
GY-DV301E/GY-DV300E makes it easy for students
to attend lectures via the Internet.
Streaming software ("Streamproducer") is provided
with the KA-DV300U, allowing up to four
GY-DV301E/GY-DV300Es to be connected to a single
PC and switched them as required before streaming.

Optical image stabiliser
To minimise jittery images when shooting with the handheld
GY-DV301E/GY-DV300E, an optical image stabiliser can be swiched in.
AE (automatic exposure) function
Brightness is managed automatically by a combination of the gain, shutter
speed and iris control.
Full auto shooting
With the GY-DV301E/GY-DV300E set to Auto, the iris, shutter speed, gain,
white balance, audio record level and optional image stabiliser all
automatically self-adjust according to the shooting conditions.
Picture quality can be adjusted manually, with individual settings available
for master black, detail, DTL frequency, V resolution, auto knee, black and
colour matrix.
Widescreen (letterbox) and 4:3 aspect ratios
The screen can be switched between 4:3 and widescreen, allowing signals
to be recorded in the desired aspect ratio.
Wide-angle and telephoto lens converters
For telephoto and wide-angle shooting, without sacrificing lens
performance, telephoto and wide-angle lens converter accessories are
available.
One-push auto focus and one-push auto iris
When the focus or iris switch is set to MANUAL, the Auto Focus mode or
Auto Iris mode can be engaged by pressing and holding the PUSH AUTO
FOCUS or PUSH AUTO IRIS button.
Cinema Gamma
An S-shaped gamma curve mode can be selected which gradually changes
gradations in the areas of dark and high-brightness. This will provide film-
like colour gradations in the recorded images.
