PEG Channel HDMI SDI Video Encoder

Description

Real-Time SD / HD Encoder for 1 HD-SDI or HDMI to MPEG-2 or H.264 on ASI or IP with CC (SDI only) & AC/3

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, the Thor H-1HD-EMS or H-1HD-EMH series HD program encoder accepts one input of uncompressed HD-SDI or HDMI digital video through a BNC connector or an HDCP-compliant HDMI input. Managed through any modern web browser, each encoder can be independently adjusted for bit rate, codecs, video, and image quality. Encoding support for MPEG-2 or H.264 codecs, 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 be multiplexed 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, alarm, and input video detection.

Question and Answers

Question:
I am looking for an encoder with 1 SDI input which delivers DVB-ready IP OUT (UDP MULTICAST). I saw this model on your website: 1 Ch SDI or HDMI HD Encoder - MPEG2/H264 I have to send 188 UDP-sized packets to the cable provider. Will this model do the job?

Answer:
Yes, this would be the ideal unit. It is commonly used for such applications for SDI to IP, and yes, all our HD/SD MPEG encoders output 188-bit packets.

Question:
Do you have any D/A converters that can take SDI and output ASI?

Answer:

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

1 SDI H-1HD-EMS

2 SDI H-2HD-EMS

4 SDI H-4HD-EMS link: https://thorbroadcast.com/product/4-hd-sdi-broadcast-encoder-iptv-and-asi-out-mpeg2-8230.html

Now, let me explain it in more detail:

SDI (Serial Digital Interface) is a standard for transmitting uncompressed digital video signals.
DVB-ASI (Digital Video Broadcasting - Asynchronous Serial Interface) is a standard used for transmitting compressed digital video and audio streams.
The process involves taking the raw, uncompressed SDI signal and using an encoder to compress it using either H.264 or MPEG2 compression standards.
Once compressed, the video can be transmitted as ASI, which is a more efficient way of broadcasting digital video streams.
Alternatively, the compressed video can also be transmitted over an IP (Internet Protocol) network for distribution.

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.
