Modern technology is innovating our world more rapidly than ever before. While this technological revolution has resulted in both better products and outcomes, on the downside, it’s also created a lot of noise and confusion. These days, clarity and simplification are seen as a benefit, especially in technical industries. AV content distribution, in particular, is one of those areas where most end users have at least a bit of basic knowledge, but when it comes to commercial integration, many feel at a loss.
Audio-visual over internet protocol—AV over IP for short—entered the market as a simplified alternative to RF distribution. From its inception, AV over IP gained popularity as a convenient way to distribute video minus the traditional cabling infrastructure needed for RF distribution. While AV over IP certainly had its challenges in the early days—not quite the magic bullet it was marketed to be—today, implementing AV over IP is far easier than it was. However, there are still important considerations to address before making the move
AV Over IP Makes Connections Easier
By its nature, AV over IP provides flexibility when setting up a network. It transforms an AV signal from a single source transmitted through a dedicated connection into digital data traveling on an Ethernet network. AV content is divided into small, digital packets with connections logically made by network software rather than by physical matrix switches, point-to-point extenders, and direct connectors. The network can be a LAN, WAN, dedicated Ethernet cable, 5G wireless, or the internet, delivering streamlined distribution without the infrastructure necessary for traditional AV.When working with an end-user, it’s worth explaining that AV over IP should not be confused with internet AV services like Netflix, YouTube, or Spotify where content is streamed. With these services, there is no real-time consideration, and delays may be arbitrarily large. By contrast, in AV over IP, systems can deliver large numbers of channels in synchronization, and time delays can be minimized.
Four things to Consider
Although AV over IP can simplify AV distribution, there are still important considerations to make when choosing how to distribute content:
- Determining the content delivery method is an essential first step in the planning process. There are a couple types of delivery methods to choose from: the first, highly compressed, low bandwidth MPEG2 or H.264, the second, a slightly less compressed MJPEG, and the last, uncompressed, zero latency, ultra high bandwidth. The decision of which method should be used, can be eased by by performing a needs analysis based on your user experience goals. For example, if a live event venue needs to stream content to another location in the audience space, latency will be a factor for the system. If a bar or restaurant doesn’t have an isolated video network, then one must consider the bandwidth consumption of the delivery method.
2. Next, determine the network requirements, this will include the number of endpoints, both source and destination, along with bandwidth. The number of endpoints and their locations will help define the type of network switch required. In a multicasting system, for example, a layer 2 switch is needed. The content delivery method will also influence bandwidth needs. Lightly compressed motion jpeg 2000, for instance, consumes a more significant amount of network bandwidth than MPEG2/H.264 highly compressed content.
3. You will also need to determine whether your AV over IP system will be distributed on a stand-alone network or shared. The choice will often depend on the size of your network, types of traffic, and the video delivery method chosen. For most systems, an isolated video network is good practice; however, there may be some applications where sharing a network with other traffic may be acceptable. For uncompressed video, an isolated network is required, but for lightly or heavily compressed content, shared networks are suitable.
4. Finally, although an integrator may have little control over who will manage the AV over IP network, it’s essential to determine who will be responsible and discuss any and all requirements of the system with this party. If a facility’s IT department doesn’t want the responsibility of managing the AV over IP system, it may be more advantageous to go with a stand-alone network instead.
