Integrated Encoder / Modulator / IP Server

QAM-IP Digital HDTV modulators are combination devices for

distribution of high definition program content.

The chassis

supports up to four input cards that can accept a variety of

program content.

The system integrates hardware encoders, a

broadcast multiplexer, digital HDTV modulator, and IPTV server.

Application Drawing: H-4HDMI-QAM-IP

The QAM-IP system provides a flexible platform for large scale distribution of any program source through modern cable TV

(QAM256) or ATSC free to air (8VSB) digitally modulated HDTV channels. All settings can be made through the front panel

keyboard and LCD. For remote management an integrated web server on a separate network interface allows control and

configuration over HTTP for all settings. In addition to Cable TV output, IPTV streaming video is provided through a dedicated

network port. All input programs are available through the IP output. IPTV can be used for wireless distribution to remote

displays. Encoding is provided by high level FPGA hardware systems, and can encode video to broadcast quality programs at

1080p60 resolutions and frame rates. QAM-IP was designed to simplify cable headend operations by combining encoding,

multiplexing, and modulation in one platform; however they are also ideally suited for in house distribution of content in hotels

and restaurants. Digital HDTV channels on different frequencies can be combined to create channel lineups of hundreds of HD

programs that can be distributed to thousands of displays over simple coax antenna cable. Additionally the platform supports

content ingestion via DVB-ASI input. This allows additional programming to be added to the digital channel and IP outputs as

sub programs. As many as 10 additional SD and 3 additional HD programs can be added to each channel carrier. The IPTV

output provides null packet filtering to reduce bandwidth and is an industry standard UDP MPEG-TS feed. This can be directly

connected to a local media server for RTSP and HTTP streaming to devices such as phones, tablets, DLNA enabled TVs, IP

set top boxes, or viewed on a computer running software such as VLC.
