AV over IP

What is AV over IP?

AV over IP offers the ability to deliver high definition video over data networks with superior quality for video and data.

Contemporary Research provides cost-effective end-to-end IPTV video distribution and control solutions made for integration in venues such as corporations, houses of worship, K-12 schools, colleges, stadiums and arenas, bars, and restaurants.

System Design Considerations

Key design considerations include:

  • Existing cabling infrastructure
  • Number of locations and screens
  • Distances involved
  • Expansion plans

Advantages of IP Video Distribution

  • Limitless scalability – IP networks can be expanded quickly by adding switches without disrupting existing switches.
  • Advanced video compression – Video compression codecs such as H.264 (also called AVC for Advanced Video Coding) make it possible to transport massive files that deliver high definition video.
  • Affordability – IP uses standard Cat 5 or Cat 6 network cabling. For new installations, IP solutions can be up to 30 percent less expensive to purchase and install than traditional AV distribution systems.
  • Reliability – IP is modular, which localizes any system failures, making them easier to locate and resolve.

AV Over IP Solutions

The flexibility of Internet Protocol Networks has made “everything over IP and IP over everything” not only a catch phrase, but a clear objective for many network designers and integrators.

Contemporary Research offers a full range of IPTV encoders that compress data for distribution over IP networks and decoder/controllers that process it for play on screens throughout enterprises of all sizes. Our Display Express Control System allows users to control power, volume, and channel selection from any device with a web browser.

IPTV Encoders

Contemporary Research IPTV encoders feature dual-channel encoders that create MPEG-2 or H.264 IPTV streams from two separate video sources. They offer low latency, accept video resolutions from 480i to 1080p and common PC graphics resolutions, and support closed captioning.

AV over IP encoder output resolutions can be changed between 480i and 1080p using the built-in scalers. IPTV encoders also accept audio from embedded SDI or HDMI, SPDIF, or analog stereo and can encode AC-3, MPEG-1 Layer 2, or AAC.

Display Express Control Systems

Stadiums, arenas, casinos, entertainment venues, as well as civic, church, and corporate video systems have hundreds and sometimes even thousands of displays, TVs, and video projectors. Contemporary Research, makes it easy to create an integrated display control system.

Drawing on our popular and easy-to-use control solution over RF Coax, we developed an audio visual over internet protocol (AV over IP) display control solution that allows users to easily set up and deploy push-button display control from any web-enabled device.
