You even get S-Video and composite for connecting to old VHS decks! DeckLink has models with both SDI and HDMI connections, so is perfect for connecting to broadcast monitors and video projectors for massive cinema style monitoring! DeckLink 8K Pro DeckLink Studio 4K DeckLink SDI 4K Connecting to Routers DeckLink cards are perfect for use with routers because they include support for video, multi channel audio, timecode and close caption data, all down the single SDI cable. This saves costs on installing routers because the single SDI router can handle all the signal types without resorting to expensive multi level routers that cost millions! Different models of DeckLink cards support built in down conversion, so you can send feeds to systems that run separate SD and HD routers. Multi rate SDI connections also support newer router designs such as Blackmagic Design's Videohub range that allow multiple video formats on the same router at the same time.

The Perfect Capture and Playback for 2110 IP Broadcast Systems! DeckLink IP cards are the easiest way to capture and play back video directly into 2110 IP based broadcast systems! They have the same DeckLink features so all your existing software will just work! DeckLink IP cards support multiple video channels plus each channel can capture and play back at the same time. This means you can build racks of servers generating broadcast graphics, virtual sets, or GPU based AI image processing, all directly integrated into 2110 IP broadcast infrastructure. You can even use DaVinci Resolve for 2110 IP based broadcast editing workstations! DeckLink IP features a high speed PCIe connection so it works on the latest Mac Pro, Windows and Linux computers. Find Reseller Three Great DeckLink IP HD Models! DeckLink IP HD DeckLink IP features 2 channels of capture and playback to 2110 IP broadcast systems via a single RJ45 style Ethernet connection. It supports all 720p, 1080i and 1080p video standards up to 1080p60. DeckLink IP HD Optical DeckLink IP features 2 channels of capture and playback to 2110 IP broadcast systems via an SFP based optical fiber Ethernet connection. It supports all 720p, 1080i and 1080p standards up to 1080p60. DeckLink IP/SDI HD For connection to both 3G-SDI and 2110 IP systems, this model has 2 capture and playback channels to 2110 IP via RJ45 Ethernet, 3G-SDI and ref out. Supports 720p, 1080i and 1080p standards to 1080p60. 10G Ethernet for Multiple SMPTE 2110 IP Channels DeckLink IP cards conform to the SMPTE ST2110 standard for IP video, which specifies the transport, synchronization and description of video, audio and ancillary data over managed IP networks for broadcast. It also keeps video sources in sync using a common PTP clock. DeckLink IP supports SMPTE-2110-20 uncompressed video, SMPTE-2110-21

Traffic shaping/timing, SMPTE-2110-30 audio and SMPTE-2110-40 for ancillary data. The big advantage of SMPTE 2110 is all video, audio and ancillary data are transported independently over the network. Plus DeckLink IP supports multicast, which is an extremely efficient way of distributing video, audio and data from a single source to multiple destinations. Built in Video Firewall for Total IP Network Security The problem with computers and 2110 IP video networks is the vulnerability to rogue software or even hackers. That’s because anyone can send data to the computer’s Ethernet connection. However DeckLink IP eliminates this problem because all video is transferred using frame buffers. It’s like a video based firewall! This means the DeckLink IP Ethernet port is isolated from anything other than video and audio. Instead, like all DeckLink cards, the video and audio are transferred to on board DeckLink frame buffers where video playback is managed and then converted to 2110 IP video channels. This means it’s totally impossible for rogue software or hackers to access the 2110 IP network directly! High Speed 4 Lane PCIe Connection With a high speed 4 lane PCI Express interface, DeckLink IP cards feature a PCIe connection to the host computer that's fast enough to handle multiple HD video channels, as well as simultaneous capture and playback on each of the channels. With PCI Express, you get very low latency combined with highly accurate time synchronization to the software that's capturing or playing video. Only DeckLink IP cards give you this performance all while using a simple and low cost 4 lane PCIe connection. This means you can install DeckLink IP into compact and very low cost computers. Plus DeckLink IP HD and DeckLink IP HD Optical are low profile, so they can be installed in rack mount servers. Supports All SD

As many online platforms as you need. Or with the ATEM Streaming Bridge, you can even link up remote broadcast networks. Includes Media Express Software If you're using video software that doesn't have direct hardware support for capture and playback, then Blackmagic Media Express is the perfect solution, plus it comes free with every DeckLink! Media Express lets you capture and playback in uncompressed YUV 4:2:2 QuickTime, AVI and DPX, ProRes, DVCPRO and MJPEG file formats. It’s a fantastic solution to capture from old broadcast decks for archiving. Because the speeds of flash based storage media can vary a lot between brands, DeckLink IP also includes Blackmagic Disk Speed Test. This means you can check the speed of media disks, with the results displayed in frames per second at various television standards.

I'm trying to receive SRT stream from Larix Broadcaster and Larix Screencaster using ffmpeg v5.1.2 running on Ubuntu 22.04.I could receive the stream and put it to a DeckLink card but the delay is very high (more than 6 seconds). The same apply why I use ffplay.I tried the basic codeffmpeg -mode listener -i srt://:20001 -c:v v210 -vf setfield=tff -r 25 -s 1920x1080 -ac 2 -ar 48000 -f decklink 'DeckLink Quad (8)'as well as playing with all the parametersffmpeg -rcvbuf 3000000 -mss 1000 -oheadbw 5 -maxbw 3000000 -snddropdelay 100000 -latency 100000 -mode listener -i srt://:20001 -c:v v210 -vf setfield=tff -r 25 -s 1920x1080 -ac 2 -ar 48000 -f decklink 'DeckLink Quad (8)'still the same result.Also the same delay when I use ffplayffplay -mode listener -i srt://:20001Is there a way to reduce this delay? When I tried with software such as OBS or vMix the delay should be around 1 second.Thanks
