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, Forward Error Correction (FEC), and Low Latency.
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.
The AVN441 allows Closed Captioning of SD signals using the Composite input. EIA-608 is supported.
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.
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
The AVN441 is easy to access and configure through the Browser Interface, and an optional AVN Control Protocol (API) is available for qualified customers. TCP/IP, HTTP, and other Internet-related protocols are supported. The Console Interface can be used for network configuration only (IP Address, Netmask, Gateway, and DNS), and not general device control.
IPTV Media Processing Platform (MPP) Component
The AVN441 is a component of the MPP from Visionary Solutions. The MPP is a high density rack mountable blade system. The MPP1700 platform holds up to 17 single slot encoder blades, or a combination of dual and single slot blades. The MPP200 has a single power source and can hold two single slot encoder blades or one dual slot blade.
