H-1HD-EMS 1 Ch HD-SDI Encoder for IPTV and ASI Distribution
H-1HD-EMH 1 Ch HDMI Encoder for IPTV and ASI Distribution
Designed as a companion encoder for the popular QAM-IP encoder series of modulators, Thor H-1HD-EMS or H-1HD-EMH series HD program encoder to accept one input of uncompressed HD-SDI or HDMI digital video through a BNC connector or HDMI HDCP Compliant input. Managed through any modern web browser, each encoder can be Independently adjusted for bit rate, codecs, video and image qualities. Encoding support for MPEG-2 or H.264 codec along with Dolby AC / 3 Audio ensures the TS programs generated by this encoder can be viewed by virtually every TV in the United States.
The output stream can multiplex into an ASI output MPTS on mirrored BNC terminals. The ASI output can be directly connected to the ASI input on a QAM-IP digital TV channel modulator. This allows additional programs to be added to the QAM-IP output channels as additional "virtual" or "sub" channels. On a TV this will Appear as channels 2.1, 2.2, etc.
Each digital channel can carry as many as 20 programs, depending on resolution and the encoded bit rate. In addition to the ASI output, the program streams are also available as UDP or RTP network video transport streams. This output is fully compliant with IGMP Multicast UDP MPEG-TS standards and can be easily injected into almost any IPTV system.
The stream is a universally accepted format, and can easily be viewed in client applications such as VLC player. In addition to network management on a dedicated NMS Ethernet port, all configuration settings and menu items can easily be viewed or adjusted from the front panel LCD and keypad. LEDs are also provided for monitoring and alarm input video detection.

This is an example of an encoder that allows for the encoding of SDI to DVB-ASI. This is not a simple conversion; uncompressed SDI needs to be encoded using H.264 or MPEG2 compression to be transmitted as ASI.

Now, let me explain it in more detail:
So, in summary, the encoder is used to compress the SDI signal into a format suitable for transmission as ASI or over IP, improving the efficiency of video distribution.
High quality & high density 24-channel SD encoder with analog composite base-band video inputs using RCA terminals for stereo & audio, output both via UDP/RTP Unicast and Multicast formats
The SPARTAN-1 is an IP streaming device that comes equipped with a single input port capable of supporting HDMI, CVBS, and SDI inputs. It is specifically designed to facilitate MPEG4 AVC/H.264 video encoding and MPEG1 Layer 2, AAC, or AC3 audio encoding, ensuring high-quality video and audio output. Additionally, this device supports a range of popular streaming protocols such as UDP/RTP (Unicast/Multicast), HLS, RTMP, and HTTP in Low Latency, making it an ideal solution for streaming over local area networks (LAN) or over the internet.
