AVN441
דגם: AVN441 can encode HD or SD video, HDMI (DVI-D with optional adaptor), Composite or Component YPbPr / RGB inputs up to 1080p 60 in an h.264 stream.

 

 

 

The AVN441 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 AVN441 blades is suitable for all applications requiring costeffective, low bit rate, high or standard definition video distribution over IP networks.

Features:
Modular Flexibility
The AVN441 features modular firmware architecture, which lowers the base
price by allowing the user to purchase only those features they need at the
moment, while 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 AVN441, 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
The AVN441 allows Closed Captioning of SD signals using the Composite
input. EIA-608 is supported.

Video Inputs
The AVN441 includes three BNC connectors for component YPbPr, RGB, or
Composite 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 AVN441 features user control of audio
parameters, including mute, pre-amp and volume.

External Device Connections
The AVN441 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 AVN441 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.
