Introduction
Overview
N143
N143, delivering media over IP networks, is a high performance live H.264
streaming media encoder. N143 is also a switcher with eight inputs and three
outputs. N143 features four HDMI inputs, two CVBS inputs, two VGA inputs,
one HDMI output, one VGA output and one Ethernet output. In addition, N143
supports four stereo audio inputs respectively associated to the VAG 1, VGA
2, CVBS 1 and CVBS 2 inputs, six microphone inputs and one stereo output
extracted from the HDMI output. N143 can be used with decoders N373 and
N383 to provide complete end-to-end streaming media system. N143 adopts
standard H.264/MPEG-4 AVC encoding and outputs two IP streams, a
stream from 480p@60 to 1920x1200@60 and a 480p@60 stream. N143
outputs resolutions from 480p@60 to 1920x1200@60 scaled based on the
sink EDID. High performance signal processing scales and optimizes video
input signals to obtain the intended viewing effects. Encoding controls can
also adjust bit rate and quality. N143 expands Audio/Video system capability
by extending the Audio/Video signals over IP networks.

N373
N373 is a high performance live H.264 decoder used with N143 encoder to
provide complete end-to-end streaming-media transmission system. N373
supports video wall function. In addition, it supports streaming resolutions
and refresh rates up to 1920x1200@60. The output resolutions range from
480p@60 to 1920x1200@60 scaled based on the sink EDID. With the
computer control software, this compact decoder offers multiple integrated
features, such as RS232, IR for flexible control and management options.
N383
N383 is a high performance live H.264 decoder used with N143 encoder to
provide complete end-to-end streaming-media transmission system. N383
can decode up to 16 IP streams. When N383 receives a single IP stream, it
has the same decoding features as N373's, such as supporting streaming
resolutions and refresh rates from 480p@60 to 1920x1200@60 and output
resolutions from 480p@60 to 1920x1200@60 scaled based on the sink EDID.
When receiving two or more IP streams (up to 16 IP streams), it supports
streaming resolutions and refresh rates up to 480p@60 and output
resolutions from 480p@60 to 1920x1200@60 scaled based on the sink EDID.
With the computer control software, this compact decoder offers multiple
integrated features, such as RS232, IR for flexible control and management
options.
