PN: H-4ADHD-QAM-IPLL
El H-4ADHD-XXX-IPLL modulador de la familia de Thor emisión está dise?ado para manejar incluso más aplicaciones que cualquier otro de 4 canales sistema de chasis que ha llegado antes de que. Este sistema tiene todos los anteriores galardonados características que se encuentran en Thor Difusión moduladores, así como varias nuevas funciones adicionales para el agregado de las aplicaciones y la flexibilidad. La plataforma ofrece 5 RF portador de salidas para la generación de canales de contenido ingeridos a través de la entrada ASI. Codificación en MPEG-2 o H. 264 es proporcionado por 4 cristalinas flujos de vídeo de hasta 1080p60 cada uno.
Tasa de bits es totalmente ajustable de 1.5 - 19 Mbps, y una variedad de codecs de audio están disponibles. Estándar de codificación de audio en MPEG-2 AAC y MPEG-4 AAC se proporcionan, así como una licencia de Dolby AC/3 audio codec. Las fuentes de Audio puede ser seleccionado de cualquiera de HDMI integrado o Analógica RCA a los puertos. Para el sonido Envolvente, entradas de audio digital que se puede "pasar a través" de modo de preservar 5.1 y 7.1 de audio que ya está codificada en Dolby formato compatible. Dos reflejado en las salidas ASI son proporcionados por los organismos de radiodifusión para mayor flexible en la distribución de los contenidos generados por los 4 encoders.
La solución ideal para los Profesionales de los Estadios y Eventos en Vivo. Se utiliza en más de la Colegiata de estadios para deportes y distribución de cualquier otro modelo.
Los programas de entrada a través ASI también pueden ser multiplexados y reasigna a la salida ASI, a?adiendo otra función a la unidad como un ASI multiplexor. IPTV es no descuidar de ninguna manera. Los cuatro programas codificados pueden ser asignados a direcciones IP únicas salidas y puertos en UDP o RTP formato. La IP de salida se puede configurar para tira null paquetes para reducir el ancho de banda de red o preservar la tasa de bits constante (CBR) de paquetes de relleno normalmente preferido por los sistemas de televisión. Todos los cuatro canales pueden configurarse de manera independiente para multidifusión o unidifusión salidas. El subtitulado se apoya en una analógico 608 CC puerto con conector RCA, un estándar de la industria para la línea 21 de la subtitulación de los sistemas. Cualquier 720 o 1080 línea estándar de se?al de video en HDMI o por Componentes (YPbPr) formato puede ser utilizado para cada uno de los cuatro canales. Igual que cualquier otro profesional de Thor modulador de chasis, este sistema puede ser configurado con firmware para QAM, DVB-C, DVB-T o ATSC canal de formato de salida.

Our 4 ch H-4ADHD-QAM-IPLL worked on the Comcast system as an inserted channel.
We have simple GUI instructions on how to set it up, we can percent it everything before the shipping, so it would be just plugged and play.
We have also other similar modulators for 1,2,8 and 12channels.
We have great flexible products and technical support
Please check those units for your reference

That is an excellent choice, and for the RF output option you'd most likely go with QAM.
DVBT is a foreign standard, since you mention you're in AZ, that won't work for you.
ATSC is standard 8VSB Off Air Antenna; so modulators can be used in this standard if you have an antenna RF infrastructure and then would like to add some custom cable channels of your own. So QAM is your bet; my assumption is that is what your Blonder Tongue units are. Oddly enough I researched that model and it is actually NTSC; which is the old analog variety of RF. So I'm not sure if you can purchase those in QAM or ATSC or they are only NTSC. The easy answer to find out is if you go to a TV on premise and do a channel scan to find channels on the coax plugged in the back, do you do Cable Scan or Off air Scan?
- Okay so then they are QAM units. So the H-4ADHD-QAM-IPLL is the unit you'd want to select.
How you can use IP TV UDP output from the H-4ADHD-QAM-IPLL CATV RF modulator / IP encoder?
An IP TV UDP output from an IP encoder can be used in several ways. Some common examples include:
Overall, the specific use for the IP TV UDP output from an IP encoder will depend on the user's specific needs and requirements.
Please review the following options:
1) H-4ADHD-QAM-IPLL: 4-channel HDMI QAM modulator/IP Encoder with QAM
latency around 300ms and IP latency of approximately 800ms.
2) H-4SDI-QAM-IPLL: 4-channel SDI QAM modulator/IP Encoder with QAM
latency around 300ms and IP latency of approximately 800ms.

3) If latency is not a concern, I suggest the H-THUNDER-8, an
8-channel QAM modulator with latency of about 500ms.

Yes, you can connect both the Gateway and the Encoder to the switch; it needs to be a smart switch with the IGMP protocol enabled.
The IGMP works in a way that it keeps the streams in the switch's memory and passes the individual streams to the specific port where the stream was requested by any IP receiver or decoder.
This is more detailed explanation how the IGMP works:
IGMP (Internet Group Management Protocol) is a communication protocol used to manage the membership of Internet Protocol (IP) multicast groups. IGMP is used by IP hosts and adjacent multicast routers to establish multicast group memberships. It plays a crucial role in enabling efficient network resource usage, especially for services like multicast video streaming. Here’s a simplified explanation of how IGMP works with multicast video streams and how it helps preserve bandwidth while allowing video access to anyone on the LAN network:
Multicast Streaming: Unlike unicast streaming, where a separate copy of the video stream is sent to each requester, multicast streaming sends only one copy of the video stream to the network, regardless of the number of requesters. This method significantly reduces bandwidth usage.
Group Membership: Devices that wish to receive a specific multicast video stream will join a multicast group. The multicast group has a specific IP address that represents all devices interested in receiving the video stream associated with that group.
Joining a Group: When a device on the LAN wants to start receiving a multicast stream, it sends an IGMP message indicating its desire to join a specific multicast group.
Multicast Router: The local router receives the IGMP join request. The router then knows that it should forward traffic for that multicast group to the network segment where the request originated.
Leaving a Group: If the device no longer wishes to receive the multicast stream, it sends an IGMP leave message. If there are no more interested receivers on the LAN, the router stops forwarding the multicast stream to that network segment.
Periodic Queries: Multicast routers periodically send IGMP queries to discover if there are still devices interested in the multicast group. If no devices respond with a desire to remain in the group, the router assumes there are no interested receivers and stops forwarding the stream to that segment.
IGMP efficiently manages network resources by ensuring that multicast traffic is only sent to network segments with interested receivers. This way, the bandwidth is not wasted on sending video streams to parts of the network where no device is interested in them.
In summary, IGMP facilitates efficient distribution of multicast video streams by managing group memberships, preserving bandwidth by directing streams only to interested receivers, and enabling open access to video content for any device on the LAN network that chooses to join a specific multicast group.
