Expanded Applications with the PCS-HG90 System
Optical HD Camera (PCSA-CHG90)
Superb Picture Quality
The PCSA-CHG90 is a camera unit designed especially
for the PCS-HG90. It incorporates three 1/3-inch
type HD sensors with a total of 1,020,000 effective
pixels each, resulting in outstanding picture quality
with high resolution and high contrast. This camera
is suitable when your requirement is for superb color
reproduction and realistic widescreen images with a
16:9 aspect ratio using the 1080i
*1
high-definition
format, which is comparable to HDTV broadcasts.
*1
1080i stands for 1080 interlaced scanning lines, a high-
definition standard. Actual communication between
endpoints is performed using the 720P format (i.e. 720
progressive scanning lines).
High-performance Pan/Tilt/Zoom Mechanism
The PCSA-CHG90 can cover a wide shooting range
with its highly accurate Pan/Tilt mechanism. It has a
very wide pan range of 340 degrees and a tilt range
of 115 degrees. What‘s more, the PCSA-CHG90
incorporates a 12x optical auto-focus zoom lens,
achieving a zoom capability of up to 48x when used
in combination with its 4x digital zoom.
FEATURES
Stunning High-Definition (HD)
Images and Lifelike Stereo Sound
The PCS-HG90 adopts the H.264 video codec, which
enables efficient transmission of high-quality images
at up to 60 frames per second in a high-definition
resolution of 1280 x 720 pixels. Also, the PCS-HG90
produces clear and natural stereo sound, using the
MPEG-4 AAC compression format. When setting the
sampling frequency to 96 kHz, an astonishing
frequency range up to 44 kHz is available through
the AUX input. And because the unit has a built-in
stereo echo canceller when using the mic input,
communication sounds far more natural by eliminating
the annoying echo that you often hear with other
systems.
High Throughput with Stable
Transmission
Maximum Bandwidth of up to 8 Mb/s over IP
Enhanced Intelligent QoS
(Quality of Service) Functions
To handle the transmission of large amounts of HD
video data at speeds of up to 8 Mb/s, while
maintaining high-quality and stable communication
over an IP network, the system incorporates the
following advanced QoS functions:
• Adaptive FEC (Forward Error Correction)
• Real-time ARQ
TM
(Automatic Repeat reQuest)
• ARC (Adaptive Rate Control)
These functions work “harmoniously” for fast and
consistent data throughput during the transmission
of video signals by adapting to any changes in the
network condition and correcting any packet loss.
For more information on the intelligent QoS
mechanism, refer to the “Technical Note” insert.
