AVN422 – H.264 HD/SD Video/Audio Encoder with HDMI and DVI-D inputs and IP outputThe AVN422 encodes high definition video in an h.264 stream (MPEG-4 Part 10/AVC). It’s used in a Media Processing Platform (MPP200 or MPP1700), a high density rack mount system. Plug a videos ource directly into the blade, plug into the network via the RJ-45 connection, and stream real-time high definition video over your LAN or WAN. The MPP with AVN422 blades is suitable for all applications requiring cost-effective, low bit rate, high definition video distribution over IP networks.

AVN422 IPTV encoders can turn video from HDMI or DVI-D sources into full-screen, full resolution Internet Protocol digital video in real time.

Modular Flexibility
The AVN422 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.  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.

Video Inputs
The AVN422 includes one HDMI input (DVI-D with optional adaptor cable) for connecting video and audio source equipment.

Forward Error Correction
For superior image quality and reliability in the most demanding network video environments, the AVN422, 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.

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. The HDMI input can carry audio as well.

External Device Connections
The AVN422 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 AVN422 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.

MPP1700 and MPP200 chassis
The MPP1700 Multi-slot chassis with power supply module will hold up to seventeen AVN422.
The MPP200 chassis with external power supply can hold one or two AVN422.
