Product Summary

Smaller, Lighter, Higher Quality
Weighing just 1.14 kgs, the Midi Encoder represents the ultimate uplink device for professionals. The optional HEVC/H.265 encoding engine can deliver the same visual quality as H.264 at close to 50% of the bitrate, reducing bandwidth costs.

Modern Design
The modular design also allows the encoder to be easily removed from the backpack for use in studios, vehicles and fly-packs.

Robust and Reliable
The Quicklink Midi Backpack automatically aggregates all available bandwidth seamlessly, without disruption of transmission – even as satellite, microwave or cellular connections are added or dropped. The per-network cellular connectivity status includes data such as throughput and network delay per connection in an easy visual display. This is also available as data displayed on the iWatch.

Optimised for satellite
The Quicklink Midi automatically optimises its transmission to maximise quality and to minimise latency. The encoder is fully tested on the Thuraya satellite, VSAT, Ka network and Inmarsat GX. The encoder also has full Inmarsat Bonded BGAN HDR Integration and control as well as inbuilt GPS functionality with custom integration to your own mapping system.




The Quicklink iStats App allows you to monitor your Quicklink video encoders wherever you are, in an instant, in real time. Synchronise the app with your encoders and continuously track their statuses and performance. The Quicklink iStats App stays on alert and guarantees you peace of mind!

Last year saw fires raged throughout Western Cape and the mountains above Glencairn Heights in Cape Town, which took three fire engines, two helicopters and 25 ground crew to extinguish. The result of these fires around the Cape Peninsula affected surrounding areas forcing residents to evacuate their homes.
As residents were forced to flee the area, broadcasters such as eNCA had the difficult job of reporting and capturing live footage of the disaster. eNCA needed a mobile solution that would allow them to broadcast quality live footage from inaccessible areas such as mountains and moving vehicles.
eNCA used the Quicklink Backpack – the perfect solution for mobile live video. This was used over a 12-14 day period where they achieved 66 live streams using one backpack producing a very successful result. Overall eNCA transferred in excess of 200GB in data.
Broadcast Deliveries Manager Sean Thomas describes why eNCA chose the Quicklink Backpack:

“We chose Quicklink for this particular story because there were a lot of areas that were inaccessible to us so we needed mobility, but the main factor for us was the cost. For us it became the quickest, easiest, deployable solution to get camera crews and reporters to areas where we would not normally be able to go. A lot of the areas were inaccessible for the SNG truck because of the fire.”

The Quicklink Backpack is one of the most advanced compact broadcasting solutions on the market. To help broadcasters produce a quality live stream, Quicklink installed the latest version of the HEVC (High Efficiency Video Coding) or also known as H.265 codec. This delivered the same video quality as H.264 but using less bandwidth.
The Backpack software also allows users to bond together multiple available networks such as 3G/4G/Wi-Fi, Satellite and ADSL, in order to improve the speed and reliability of the internet network. The software automatically detects and seamlessly adjusts to suit the available network conditions whilst maintaining optimum broadcast quality.
By using the Quicklink Backpack eNCA were able to report on a large area of the fire and were mobile enough to get the story as it broke out. Sean Thomas adds:

“Our cameraman were using a Panasonic P2 camera with SDI connected to the Backpack. From initial boot up, it took 5 minutes to send a live stream with embedded audio using the 8 inbuilt high gain cellular modems.”

eNCA’s MCU has already increased their order for more Quicklink Backpacks hoping to deploy them to their other bureaus so they can have live contributions from different parts of the country.
