This article outlines some fundamental concepts around wireless video transmission and aims to let those professionals who want to look for the good commissioning streaming video solutions for their own project.
Before choosing a proper solution, it is important that you understand some fundamental concepts around wireless video transmission. These concepts are critical to the success or failure of your project. As a consequence of not fully understanding these concepts, you might pay a high price for a solution that performs poorly or, in the worst-case scenario, not at all.
As both a leading solution provider in the field of low latency, low bit rate, real-time wireless video transmission, CVW understands the issues and decisions you may come across. Developed over the past 10+ years CVW wireless video transmission technology and service are guaranteed to deliver the best experience – be it cost or performance related.
Whilst this section is intended to give you brief overview of the main points, we are always happy to discuss and answer any specific queries you have in relation to your own project, whether it be for mobile wireless video transmission, rapid deployment, or temporary or fixed camera shooting.
Bandwidth is important for many reasons on distributed networks.
The core issue for any real-time live wireless video transmission solution is bandwidth. This is the amount of data the system needs to deliver a good quality picture in real time.
Bandwidth is measured in Megabits per Second (Mbps) or Kilo Bits Per Second (kbps). It is a measure of how much data a network can transmit. For example, 2.5G can only deliver around 30Kilo Bits per second whereas 4G can deliver multi megabits per second.
Bandwidth is expensive and charged for by usage, so the more you use, the higher your air-time bill. There also needs to be enough bandwidth available to transmit the required video quality.
Video compression is the traditional solution to this problem. The more a video is compressed the less bandwidth required to transmit. Compression however, degrades the image quality, and in some cases destroys it completely.
CVW’s fully optimized video compression technology delivers higher quality video images at lower overall bandwidth usage than the competition.
Our solutions have kept pace with the developments in video technology. CVW’s video streams look better and cost much less than our competitors. We consistently out-perform other systems on the market – many of which cannot even operate in very low bandwidth situations.
Latency is the measurement of delay in any given solution.
For example, how long it takes a video to get from the transmitter to the receiver. Or how long it takes for the camera to move after you move a PTZ joystick.
In latency terms, 1 second is a long time! It is also the difference between a successful operating system and an unusable one.
CVW’s wireless video transmission technology minimises latency. With CVW system an operator setting up a whole system immediately sees the result without having to wait for the video to catch up.
Distributed networks are notorious for being unstable. They suffer fluctuations in connections and in available bandwidth.
To successfully maintain connections across these networks, systems must have intelligent transmission protocols. CVW’s multiple video transmission solution is designed to recognise and adapt the bandwidth to optimise prevailing conditions.
Automatic connection is one of the main benefits of our solution. This ensures whenever there is a link to the other side of the network, the system connects automatically.
For the client this generates cost savings due to less cables and its ability to move smoothly in most cases.
Plug & play
Delivering a functional, high performance wireless video transmission system involves some hugely complex issues. The associated technology, clever as it may be, is useless if too complicated to set up and run.
CVW solutions make set-up and connection as easy as possible. Our range of software and hardware wireless video transmission products are plug and play, so your system will be up and running with minimal effort.
Usually, all you need to do to get a transmitter connected to your camera is power it on. Best practices learned through years of working with deployments and installations is built into our systems, enabling a rock-solid performance when connecting equipment.
With CVW, pre-configured encoders and networks mean that one-man installs are often the norm. The deployment time from power on to a working solution is around 2 minutes.
Problem analysis and resolution
In the unlikely event anything goes wrong further down the line, a CVW wireless video transmission system makes it is easy to diagnose and find the problem. Our supported team members will give our support for any problems quickly and effectively. This includes issues caused by external factors, e.g., power, camera equipment or network behaviour.
