Hybrid AV Distribution Solutions

What is a Hybrid AV Solution?

A hybrid AV distribution network utilizes both RF coaxial and category cabling. This is a preferred approach for venues that would like to leverage existing coax infrastructure while expanding the network to include IPTV capabilities.

Sites as diverse as entertainment venues, arenas, stadiums, casinos, corporate, houses of worship and civic buildings find hybrid AV networks to be a cost effective and efficient means of migration

System Design Considerations

System design depends on several factors, including:

  • Number of locations/screens to be served
  • Distances involved
  • Expansion plans
  • Any existing infrastructure that may be utilized

Advantages of Hybrid Video Distribution

Digital RF and IPTV

Digital RF and IPTV are closely related: each uses encoders to create digital MPEG programs. The key difference is that the MPEG programs are carried as a channel in RF and as an IP stream over Ethernet.

Utilizing RF and IP in video distribution offers these advantages:
  • Affordability – lower installation costs, as additions are only made where necessary instead of replacing an entire infrastructure
  • Highly scalable – RF networks can start small and expand to hundreds of channels and TVs at any time. While IP networks can be expanded quickly by adding switches
  • Flexibility – add IPTV infrastructure only where needed
  • Customization - Utilizes the best of each technology, allowing users to piece together what works for their infrastructure

HDTV Modulators and IPTV Encoders

Contemporary Research’s HDTV Modulator-IPTV Encoders were designed and developed for IP/RF convergence in hybrid video distribution networks. Units create QAM digital cable channels or 8VSB air modulated channels as well as MPEG-TS IPTV streams. Contemporary Research IPTV encoders create MPEG-2 or H.264 IPTV streams from various video sources.

CR modulators and encoders include robust features such as built in scalers for edge-to-edge presentation, dual-language SAP audio, and Emergency Alert messaging capabilities.



The QMOD-SDI HDMI is a professional dual-channel frequency-agile RF Modulator/Encoder ideal for distributing live video from SDI and HDMI sources as well as digital signage content from media players or PCs.

HDTV Tuners, IPTV Decoders, and Display Controllers

CR’s IPTV decoder/controllers provide integration-friendly IPTV decoding with built in display control. They are compatible with unicast or multicast UDP and RTP IPTV streams and will accept MPEG-2 or H.264 single program or multiple program transport streams.

The ATSC HDTV tuner series is available for commercial integration systems with projectors and professional displays without built-in TV tuners. These tuners can receive ATSC, NTSC, and clear QAM formats and are compatible with digital channels encoded in MPEG-2/H.264.

The HD video outputs can be set for native resolution or scaled up to 2160p. All tuner functions can be controlled with infrared and 2-way RS-232/IP Telnet. Tuner/controllers provide all the features of a tuner with the ability to pass control commands to the display devices for power on/off and source selection.

The ICC1 series of display controllers are integration friendly and offer 1-way control for power, volume, and channel selection. They are compatible with most brands of IR or RS-232 controlled TVs, displays, or projectors and with Contemporary Research's Display Express software or other custom programmed control systems.
