Con Maevex, HKCAD visitors share experience of air traffic controllers in Hong Kong

Visitors to Hong Kong's Civil Aviation Department can see what air traffic controllers see, thanks to the Matrox Maevex AV over IP H.264 encoder and decoder system. A solution that allows live images to be transmitted from the control tower, recorded with a camera at 1080p60, to a remote Epson HD projector located 2 km. away.

With image transmission at 1080p60, with minimal bandwidth consumption, from the camera installed in the air traffic control tower of Hong Kong International Airport to the aviation gallery of the Education Path of the Hong Kong Civil Aviation Department (HKCAD), located at 2 kilometers away, Matrox Maevex ensures that visitors to the Hong Kong Civil Aviation Department can live the same experience as air traffic controllers, remotely observe aircraft takeoffs and landings.

Located in the offices of the Hong Kong Civil Aviation Department, The Education Path aviation gallery is designed to simulate the functions and situations of the Department of Civil Aviation, as well as to promote various activities of the civil aviation industry.

The Education Path has several high-end galleries and the Hong Kong Department of Civil Aviation wanted to add a new one that would feature a live air traffic control display.

The initiative required high-quality transmissions with minimal latency of the airport's air activity, which takes place between the restricted area of ​​the air control tower and the remote aviation gallery of the Education Path. In addition, It was crucial that transmission could be carried out with the existing network infrastructure, equipped with a bandwidth of 8 Mbps, and that it would not negatively affect network administration due to high bandwidth consumption.

Video distribution

While some of the initially selected AV over IP platforms were capable of sending air traffic activity, Content was typically transmitted with bandwidth bitrate values ​​of 12 Mbps or higher. Consequently, video streaming and performance eventually suffered.

The local IT solutions provider, Amara International, recommended an alternative for video distribution, Matrox Maevex H.264 encoders and decoders. These devices can transmit video and audio in Full HD at 1080p60 with minimum and adjustable bit rates between 100 Kbps y 25 Mbps.

Hong Kong Civil Aviation Department wanted to distribute AV content over existing IP network, by using standard wiring and equipment. Maevex AV over IP devices not only met that requirement with open H.264 encoding, But Amara found that the included Matrox PowerStream software provides a wide selection of control options that enable easy remote management of devices., transmission sharing, adjusting streaming/recording parameters and customizing bitrate.

PowerStream

At the moment, Hong Kong's Civil Aviation Department uses Maevex in its airport's air traffic control tower to transmit live images of air traffic, recorded with a camera at 1080p60, through your local access network (LAN) even a projector Epson HD remoto, located at 2 kilometers away. Gracias a PowerStream, Amara has been able to set the bitrate limit to an optimal setting of 8 Mbps, which ensures smooth and interruption-free video transmission.

Thanks to high-quality video transmission, with minimal bandwidth consumption, from the airport control tower to the Education Path aviation gallery, In the exhibition you can live the real air traffic control experience that the Hong Kong Civil Aviation Department wanted to achieve.

Application in signage and collaboration

Maevex AV over IP solutions enable the extension of Full HD video and audio to 1080p60 over standard IP networks with unicast and multicast support for digital signage, collaborative video walls and many other applications.

Bit rates can be set between 100 Kbps y 25 Mbps, and multiple transmissions can be enabled on standard 100 Mb y 1 000 Mb.

Maevex H.264 encoders even enable software decoding on non-Maevex devices. Besides, can be used as recording devices, allowing you to record Full 1080p60 MP4 files to NAS or network shared drives to store sensitive and important AV content. Maevex drives ship with Matrox PowerStream software, allowing easy remote management of Maevex devices and their functions.
