AVN443
דגם: AVN443 can encode HD or SD video, SDI and HDMI (DVI-D with optional adaptor cable) up to 1080p 60 in an h.264 stream.

 

 

 

The AVN443 can encode high or standard definition video in an h.264 stream (MPEG-4 Part 10/AVC). It’s used in a Media Processing Platform (MPP), a high density rack mount system. Plug a video source directly into the blade, plug into the network via the RJ-45 connection, and stream real-time high definition (with optional HD modules) or standard definition video over your LAN or WAN. The MPP, with AVN443 blades, is suitable for all applications requiring cost-effective, low bit rate, high or standard definition video distribution over IP networks.

Features:
Modular Flexibility
The AVN443 features modular firmware architecture, which lowers the base
price by allowing the user to purchase only those features they need at the
moment, while at the same time maintaining the flexibility to upgrade in the
future as requirements change. The list of optional add-on-modules
currently include, 720p, 1080i (with 1080p @24 support), 1080p @60, and
Forward Error Correction (FEC).

Superior Audio/Video Quality
h.264 (MPEG-4 Part 10/AVC) hardware compression and Visionary
Solutions’ optimized transmission technology provide a high or standard
definition, full frame rate, IP video stream. The stream can be
viewed by an unlimited number of clients on a LAN or WAN provided
that bandwidth is available. Image resolutions are configurable based upon
purchased modules. The base model includes 480i SD encoding, with Closed
Captioning (CC) support. Optional modules allow FEC support and image
resolutions to be configured up to 720p, 1080i (with 1080p @24 support) or
full 1080p at 60 frames per second. The total bit rate can be configured from
5 to 20 Mbps for HD and 2 to 10 Mbps for SD. The audio compression is either
AAC (128 to 512 kbps audio encoding, average bitrate) or MPEG-1 Layer 2 (64
to 384 kbps audio encoding) with up to 48 kHz sample rate.

Forward Error Correction
For superior image quality and reliability in the most demanding
network video environments, the AVN443, with optional FEC module,
incorporates SMPTE-2022 Pro-MPEG FEC Code of Practice # 3, Release 1
and 2. This allows FEC enabled receivers to monitor the stream and
recover missing packets.

Closed Captioning
Using the SDI / HD-SDI input, the AVN443 allows Closed Captioning of both
SD and HD signals. Supports EIA-608 and EIA-708.

Video Inputs
The AVN443 includes one BNC connector for SDI, HD-SDI and 3G inputs, and
one HDMI input (DVI-D with optional adaptor cable) for connecting video and
audio source equipment.

Audio Inputs
A terminal block connector provides audio inputs for Balanced and
Unbalanced connections. This allows for easy onsite connections regardless
of the cabling outputs of the audio source. There are also two RCA audio
connectors (L/R) which support only unbalanced connections, and the HDMI
input carries audio as well. The AVN443 can also extract embedded audio
from the HD-SDI input.

External Device Connections
The AVN443 includes a serial connection via an RJ-45 connector. This
connector can be used as an RS-232 port (full duplex, no hand shaking) or an
RS-422 (full-duplex) port. These ports allow the AVN443 to interface with
external devices such as terminal emulation equipment.

Management & Configuration of the device is
accomplished by any of four methods: PackeTV™ Manager (2nd generation),
console menus, a Web interface, or the AVN Control Protocol API. TCP/ IP,
HTTP and other Internet-related protocols are supported.
