12 HDMI input to CATV RF QAM Output and IPTV output. PN : H-12HDMI-QAM-IPLL
Description

12 HDMI Channels to CATV RF Coax Digital Modulator QAM, ATSC, DVB-T, ISDB-T, format up to 1080p60 low latency with IPTV Streamer and ASI Out

The new high capacity H-12HDMI-QAM-IPLL Encoder Modulator from Thor Broadcast has a new sophisticated redesigned platform for enabling modulation of up to 12 HDMI sources and 12 CVBS CC(Closed Caption) sources simultaneously. This unit has the ability to ingest IP Transport Streams and multiplex them among the RF output channels, similarly you can also input a single ATSC (or other RF modulation standard) and add its transport streams among the QAM output. This unit comes standard with a plethora of options to help you add extra transport streams from various media to build your own RF headend quickly and easily without extra hardware.

The H-12HDMI-QAM-IPLL supports MPEG2 and MPEG-4 AVC/H.264 video encoding and MPEG1 Layer II audio encoding (MPEG-2 AAC, MPEG-4 AAC Optional), Dolby Digital AC3, as well as AC3 pass through.

This unit has the ability to multiplex, create, and add program streams to your RF QAM cable channels cost-effective design make this device widely used in variety of digital distribution systems such as CATV headend cable systems

Create your own digital signage systems, and add HDMI sources to your existing QAM cable system in a single 1RU high density encoder modulator from Thor.

 

HDMI MULTIPLEXER

The Thor Broadcast HDMI Encoder modulator can be set up as a multi-channel video switcher so you can put multiple videos on one RF 6mhz frequency.

Since QAM 256 contains 38Mbps data storage, it means we can use all that bandwidth to place several programs via multiplexing on a single RF channel, each 6Mhz can carry any encoded video bitrate so long as they don't exceed the 38mbps total. For example, if we have a 4 source modulator, we can set the encoded bit rate on each video to 9.5Mbps, so 9.5 x 4 =  38Mbps. We can fit all of those programs in one QAM 256 channel.

So let's say that we choose 57mhz, which is CH2 on the QAM RF spectrum, we will be able to modulate 4 video's onto channels 2.1, 2.2, 2.3, 2.4 simultaneously.

This is important in case we want to insert multiple video programs on limited RF space occupied by different channels from the cable company; or other modulators creating channels in your CATV lineup.

Question and Answers
Question:
As you know, the manual states that I am supposed to use DATA 2 for the IP Stream output. As we noted under the IP Stream settings, DATA 2 is the only port that is referenced for IP Stream output. I can prove that DATA 2 is the IP Stream output, as when I disable the TS output on DATA 2 my data activity at the switch ceases on both Data 1 and Data 2 ports. Also, when I have the TS output enabled for Data 2, I only get switch activity when Data 2 is connected to the switch. Disconnecting Data 2 while Data 1 is still connected stops the switch activity. Another observation: When I have set the DATA 1 IP to 10.0.17.20, I can ping this address when either the DATA 1 or the DATA 2 cable is connected. This tells me that DATA 1 and DATA 2 are using the same IP Address.

Answer:
DATA1 is GE port and for IP input, DATA2 is GE port and for IP output. DATA3 is for upgrade encoding module. DATA1 and DATA2 are share port. same IP for them . it's like a small 2 layer switch, through many ports but only have one IP address. If you need IP input and output at the same time, please connect DATA1 and DATA2 to one VLAN.
