Resolving Issues With Live Wireless Video Transmission


Last updated Jun 24, 2019 | Published on Jun 23, 2019 | Wireless Video

The transmission of wireless video to a live audience requires your team to work with the latest technology and to mitigate many of the technical challenges others face. Our team at VidOvation has helped companies throughout the industry overcome technical problems within their live video feeds, and within this latest post, we’re highlighting a few challenges and associated solutions.

Image Distortion

One of the more common issues associated with live video transmission is image distortion. Image distortion occurs during compression and as a result of ineffective use of the latest technology. The leading wireless systems should now be using interframe compression in order to mitigate distortion during live video footage.

On-Air Latency

For live events, particularly live sports coverage, any amount of on-air latency is unacceptable. It limits the ability of the audience to experience and enjoy the live feed. The latest technology from VidOvation is now being used to significantly reduce on-air latency. For example, the AB512 and the AB507 reduce on-air latency to just 7 milliseconds, which is known as sub-frame latency. This level of latency helps minimize issues with lip syncing that can occur during live events.

Infrastructure Costs

The significant expense in building infrastructure has limited companies trying to shoot live events for national audiences. Until recently, they had to invest in broadcast technology that placed satellites on moving vehicles to transmit information. Now, the wide availability of cell towers has made streaming live events much simpler and more cost-effective. Companies are able to simply pay for bandwidth across the network as and when they need it, only incurring costs when they use the data. The use of wireless transmission systems is also improving the speed of data transfer and eliminating issues that can occur when transmitting data via satellites.

Connectivity Loss

In some cases, your live video feed will be interrupted if you don’t have wireless camera coverage in multiple areas of the facility where the live content is being recorded. Any connectivity loss can be significantly damaging to your brand and could cause you to lose the trust of your audience for the long term.

Ensure that you are taking all the required precautions to keep the connection strong during live events. For example, you should be working with solutions that incorporate automatic frequency hopping and analysis. Our solutions at VidOvation offer continuous scanning of the 5 GHz spectrum and monitoring of RF channel conditions to ensure a clean and clear signal, regardless of the outside conditions.

Low Bit Rate

A low bit rate is another factor behind poor image quality. The higher the level of bit rate achieved with your wireless video transmissions, the greater the clarity of the image you will be able to offer. And that’s why many manufacturers in the industry are now using dynamic modulation, which automatically modulates the transmission based on the RF signal, helping support a higher bit rate for each transmission.

Companies can also achieve greater video quality by deploying FEC (Forward Error Correction). Working with a specialist such as VidOvation can ensure that your wireless video transmissions only use FEC when required, helping improve transmission reliability for low latency video while reducing the total cost.

Improve Team Communications With Bidirectional RF Radio

Perhaps one of the largest challenges associated with live events is ensuring that your team can communicate with one another during their event coverage. Your camera team must be able to communicate with the director while planning their footage changes during the event.

Producers must be able to find the best angle for a particular piece of action during the live transmission, and this involves working with all camera team members. That’s why so many organizations are now deploying wireless video transmission with bidirectional RF radio. The technology helps capture radio transmissions across all areas of the venue and allows team members to make sure their message is heard clearly. This helps ensure that audiences don’t miss any of the live event as teams can communicate effectively in real-time without any missteps or confusion.
