Torrent Q20IP 20 Channel IPTV RF EdgeQAM
The Q20IP 20 channel RF EdgeQAM is the newest member of the Company's
TorrentTM family of high performance, low cost per stream DTV
modulators.
The VideoPropulsion Q20IP maps video transport streams from an IPTV
source onto 20 QAM channels in four sets of 5 adjacent channels. Each
256QAM Annex B channel is capable of up to ten 3.8 Mbps SDTV, three 12.9
Mbps EDTV, two 19.4Mbps HDTV streams, or any other mix of streams that does
not exceed the total 256QAM Annex B bitrate.
Integral upconversion to RF output provides the ultimate in flexibility by
eliminating the need for external upconverters and messy cabling.
The completely self-contained Q20IP can be configured and maintained from a
web browser.
Product Highlights - Benefits
- Twenty RF QAM channels with 6 MHz bandwidth, sixteen channels with 8 MHz bandwidth
- Higher QAM density and lower cost per stream
- User selectable 16QAM, 32QAM, 64QAM, 128QAM, and 256QAM modes
- Adaptable to a wide range of applications
- Upconversion to 50 - 860 MHz RF output (also available without upconversion)
- Eliminates external upconverters and cabling
- Web-based management and configuration GUI
- Flexible, targeted configurations with minimal development

The Q20IP hardware collects MPEG-2 transport streams directly from
an IPTV stream and multiplexes them into multiple program transport streams
that are transmitted with upconversion using 16QAM, 32QAM, 64QAM, 128QAM,
or 256QAM modulation with variable symbol rates up to 7 Msymbols/second.
Forward Error Correcting (FEC) encoding complies with ITU-T J.83 Annex A
(DVB/DAVIC/EuroDOCSIS/IEEE802.14), Annex B (DigiCipherII/SCTE/DOCSIS/IEEE802.14),
and Annex C (Japan).
Options for the Q20IP include an additional 10 QAM channels, encryption
of the output streams, and IF output.
