4 Ch HD-SDI Encoder MPEG2 and H.264 with CC & AC/3

Description

H-4HD-EMS 4 Ch HD-SDI Program Encoder

Real-Time Encoder for 4 HD-SDI to MPEG-2 or H.264 on ASI or IP with CC & AC/3

Designed as a companion encoder for the popular QAM-IP series of encoder modulators, Thor H-4HD-EMS series HD program encoders accept up to 4 channels of uncompressed HD-SDI digital video on 4 BNC connectors. Managed through any modern web browser, each encoder can be independently adjusted for bitrate, codecs, and video image quality. Encoding support for the MPEG-2 codec, along with Dolby AC/3 audio, ensures that the programs generated by this encoder can be viewed by virtually every TV in the United States. All four program streams are multiplexed into an ASI MPTS output 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 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. In addition to network management on a dedicated NMS Ethernet port, all settings and menu configuration items can easily be viewed or adjusted from the front panel LCD and keypad. LEDs are also provided for alarm monitoring and input video detection.

Question and Answers

Question:
We are looking for a simple, cost-effective solution to transmit four (4) SDI camera feeds from one site to another. These cameras are being remotely controlled, so we are looking for a low-latency, as close to real-time solution as possible. Looking at the H-4HD-EMS (4 HD-SDI Broadcast Encoder IPTV and ASI Out MPEG2 / H.264 / AC3/ 1080p / CC) unit. Below are a few questions: We have a dedicated site-to-site 100 Mbps VPN connection between both locations. Do you envision any issues with latency, and would/could this provide an almost real-time solution, or if not, what would be an estimated/expected delay between what is sent and what is received at the remote end? Is there a corresponding single unit IP-SDI 4-out device? Or is the H-IRD-V3-IP the only native SDI output device? It seems that the only other compact and low-cost alternative would be the H-IP-HDMI, and then we would need to convert the HDMI output to SDI?

Answer:

Yes, that would be the ideal unit; correct, there would still be some latency because any encoder, regardless of the manufacturer, will have latency. The only way to remove latency is to send those SDI links over a single fiber; that is the only realistic solution. If you have to use IP, then the V3-IRD is the only solution we have with SDI outputs; the IP-HDMI is slightly less expensive, but you rightly mentioned you will need converters for that. As for the data rate, I believe that would suffice since you could ideally encode in MPEG4 since you need SDI back out on the far end. It's hard to estimate what kind of delay you'd be looking at; in this case, the encoder, decoder, and IP link will all introduce latency; between all pieces, I can't imagine it being better than 1-2 seconds. Again, that's an estimate; it could be worse. It most likely won't be better unless it's a very short distance.

Question:
I'm looking for some info on multiple SDI to ASI IP encoders, MPEG2, with AC3 audio. Could someone please call me to discuss specs/features?

Answer:
Here is the 4 SDI encoder, which might be a better fit if you don't need the RF. https://thorbroadcast.com/product/4-hd-sdi-broadcast-encoder-iptv-and-asi-out-mpeg2-8230.html This unit can do both MPEG 2 and H264 independently on each stream for input on the SDI side. We do have an 8 Channel version, but it's H264 only. https://thorbroadcast.com/product/8-hd-sdi-broadcast-encoder-iptv-streamer-and-asi-out-h-264-8230.html The IRD-V3IP is what you'll need on the back end. https://thorbroadcast.com/product/ip-to-hd-sd-multi-standard-integrated-receiver-decoder-mpeg2-8230.html

I think you mentioned you might need 8 of the IRD; does that mean you'll need 2x the encoder?

Question:
I'm part of a project building a digital television repeater for amateur radio (TV) operators in Australia. I have been looking for an economically priced SDI to ASI encoder for 2 inputs. I have purchased a S/H ASI to DVB-T modulator, which is an ENENSYS Netmod DVB-T/H. Do you have a 2- or 4-channel version of the 8 HD-SDI Broadcast Encoder IPTV Streamer and ASI Out, H.264 / AC3 / 1080p? In addition, do you subsidise costs for a club project? Happy to assist in adding recognition to 'THOR Broadcast' for the encoding. Cost for 1 x encoder, please. Another question: we are wanting to add Teletext to one of the HD channels. Does the encoder allow AUX PES to be multiplexed into the TS ASI via the ASI input? Can it select a new PID and multiplex in sync with TS PCR? Many thanks, and please consider assisting with our club DATV project in Australia. The repeater call is VK3RGL and shall be atop Mt Anakie, Victoria. The club is the Geelong Amateur Radio Club

Answer:

Yes, we do have 2 and 4-channel SDI encoders available with IP and ASI output.

The encoders support CC608 and CC708, but the data would need to be embedded into the SDI signal. We do not have a way to inject Teletext via ASI and mux it.
