This unique modulator allows for ASI input and ASI output for program management to decode and output via IP and RF. It provides a more powerful receiving ability of various Transport Streams that come from an encoder, multiplexer, DVB gateway, scrambler and video server. In addition, the modulator also has the ability of outputting RF while simultaneously sending out IP. This device supports local and remote control through NMS software. This unit has wide array of functional uses from Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.

Questions:
I discussed this with our engineer, and he believes you are receiving ASI with an MPTS (Multi-Program Transport Stream). Is that correct, or is it only a single, non-muxed TS?
If it is MPTS, what is the ASI bit rate? Our ASI-to-QAM modulator can generate up to 4 physical QAM channels.
One 256-QAM channel can carry up to 38 Mbps, so if multiple transport streams are multiplexed on the ASI input, we can distribute them across four different RF frequencies.
Please find my answers bewlo :

The ASI does have MPTS. We have five transport streams available on ASI output. I can configure up to 3 ASI outputs but cannot select specific TS to show on specific ports. All five on each ASI port.
If it is MPTS, what is the ASI bit rate? Our ASI-to-QAM modulator can generate up to 4 physical QAM channels.
I cannot see what the ASI bit rate is out of this receiver.
One 256-QAM channel can carry up to 38 Mbps, so if multiple transport streams are multiplexed on the ASI input, we can distribute them across four different RF frequencies.
We have found that if we keep the QAM channel at or below 34Mbps, the crappy tv’s on our network will work fine. As of now we pick four of the five TS on one QAM RF channel and mux the fifth TS onto another QAM RF Channel. Having the one Modulator output multiple QAM channels is a benefit as we can split the five across two QAM channels and assure we keep the QAM data rates well below our 34mb mark.
Lastly – It feels like the asi stream bit rate is too high for the drake MQM and MQL modulators we have. The buffer max’s out. I also have an old cisco qam modulator we use for testing and there is an overflow error which leads to a higher ASI rate than they can process.
IPTV to 32 RF channel Analog NTSC PAL Modulator
IPTV streams to 32 Analog channel modulator for Modulation Digital IPTV MPTS or SPTS's strems, digital programs to analog NTSC modulated channels. Most analog modulators have Baseband Video Audio CVBS inputs, this unique modulator has an IPTV input, decodes those streams internally to analog CVBS format and modulates them on the NTSC analog channels carriers.
IPTV to 16/32 CLEAR CHANNEL RF QAM/ATSC Modulator
CABLE TV Headend in a Box. QAM modulator for IP Edge QAM / ATSC /DVB-T /ISDB-T applications. This 1RU chassis has 2 GE inputs with SFP interface allowing up to 1024 channels TS streams of UDP/RTP, unicast and multicast streams. Maximum input of each GE input is 840 Mbps that will be output through the RF output on 16 non-adjacent QAM carriers in the range of 50-960Mhz.
