Video over IP is a widely used method of delivering video content to an audience over a local or wide area network where media inputs are deconstructed into different streams and then sent over an IP network as individual data packets. Meaning users can watch real-time video and audio content, similar to watching a television broadcast. In the context of media production networks, video over IP can be perceived as a newer alternative to SDI broadcasting which has been a standard for many years.
IP multicasting allows the distribution of video and audio to any supported number of displays on a network. In digital signage, for example, a single content source can deliver multimedia to hundreds of displays through one AV transmitter with no need to run dedicated video links from a back room to displays in lobbies. For easy integration, consider using transmitters and receivers that install directly into the existing LAN infrastructure.
Use IP video multicast switches and set the transmitter and receiver to the
same multicast or unicast channel so that all IP multicasting settings are automatically configured. Just connect your source, your display(s) and a network switch.
Video-over-IP technology facilitates video signal and format management and opens up new possibilities for user-friendly and highly-scalable video wall control. Set up a video wall by transmitting video signals from multiple sources to multiple screens over an Ethernet network.
Video distribution over IP can be used in several settings including:
KVM-over-IP technology extends keyboard, video and mouse (KVM) signals from any computer or server over an IP connection, enabling an effective way to remotely manage servers regardless of their physical location. Integrated with BIOS-level access, system administrators can monitor and respond to server issues from virtually anywhere over an internet connection. For this reason, server management with remote KVM switches has become a critical component in most data centers today.
Network video servers, also known as IP video servers, enable the transfer of video feeds into other video servers/PCs or deliver streams for direct playout (via IP interface or SDI). For example, in surveillance, an IP video server can be used to turn any CCTV camera into a network security camera with an IP-based video stream capable of being broadcast over an IP network.
A video matrix switch, also called a cross-point switch, is a type of switch that connects multiple inputs to multiple outputs to form a multipoint matrix. Video matrix switches can be configured to switch any supported number and type of inputs and outputs. Each input on the switch can be routed to any output source or receiver, or the same input can be routed to all outputs or any combination in between. For example, an 8 x 8 matrix switch can route eight inputs to eight outputs, one input to eight outputs or any combination up to eight. This eliminates the need to manually move cables to display video from different sources on different screens. It is most commonly used now with HDMI video.
An IP video matrix system allows video to be distributed, extended and formatted over an IP network, unicasting or multicasting individual video signals to a matrix of screens and displaying video content on multiple video screens. This gives users an infinite number of individual video distribution configurations. It’s commonly used in applications such as broadcast, control rooms, conference rooms, healthcare, industrial manufacturing, education and more.
Video-over-IP encoders convert video interface signals such as HDMI and analog or embedded audio signals to IP streams utilizing standardized compression methods such as H.264. Black Box provides solutions that allow you to transmit high-quality video over a standard IP network for display of HD content on one screen — or multicast signals to multiple displays — check out the VS2000-ENC H.264 Encoder page for more info.
Video-over-IP decoders extend video and audio over any IP network. Black Box offers solutions that can receive high-quality video over a standard IP network like the VS2000-DEC H.264 Decoders. Because the decoder uses H.264 compression and requires very low bandwidth, it's extremely efficient when decoding full HD video and analog audio. It also supports AAC audio encoding, so the audio signal can be delivered with low bandwidth but high quality.
Video-over-IP transmitters and receivers allow the extension of AV connections from a simple point-to-point to a multi-point to multi-point setup via LAN.
Network-based, high-quality video and audio distribution are becoming a challenge due to increasing bandwidth requirements and end-user expectations. New network technologies and standards, as well as compression algorithms, will help mitigate these challenges, yet there are still additional costs for required infrastructure and migrating legacy components. Nevertheless, current developments in AV and KVM technology allow the transmission of high-quality video that consumes less bandwidth than ever before and make management of small-to-large scale IP-based AV networks both comfortable and future-proof.
Here are some takeaways when considering high-resolution image distribution for your project:
You should ask yourself some questions before starting your research on components to build-out your AV-related application:
Black Box can help you design an AV- or KVM-over-IP distribution system tailored to your specific needs. Based on extensive experience and a unique product portfolio, our experts will recommend you the right mix of components.
Black Box IP video solutions enable you to extend P2P or multicast HDMI video and audio to up to 256 screens on a network, making them ideal for distributing digital signage content or other HD video and audio across an Ethernet network.
