Ofrece un motor más potente de la recepción de capacidad de los diversos Flujos de Transporte que vienen de un codificador, multiplexor, DVB puerta de enlace, scrambler y el servidor de vídeo. Además, el modulador también tiene la capacidad de producir una se?al de RF, mientras que, simultáneamente, eliminando el TS por el LD de la codificación, la convolución de entrelazado y QAM la modulación. Este dispositivo es compatible con control local y remoto a través del software NMS. Esta unidad dispone de una amplia selección de los funcionales de los usos de la Radiodifusión, Servicios Interactivos, la Recopilación de Noticias y otras aplicaciones de banda ancha por satélite.

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.
