Extron AV solutions promote vinuniversity's teaching work

DTP systems, XTP and audio Extron provide all the functions and capabilities necessary to assist students in their training.

Two of the largest laboratories in the VinUniversity incorporate a large number of display devices and an independent AV switching and distribution matrix system Extron.

VinUniversity is a private non-profit educational center located in the Gia Lam district of Hanoi in Vietnam. Its mission is to educate and develop the talent and skills of youth, as well as providing career paths within the country.

Campus buildings include auditoriums, Classrooms, laboratories, multipurpose rooms, a medical simulation center and a technologically enhanced library. Each structure also provides meeting and conference rooms.

This university promotes the use of new training methods that contribute to the proactive learning of students so that they master teamwork and their social skills within a wide variety of professional careers.

To support this mission, the school needed high-performance AV signal switching technologies and robust sound systems, plus easy-to-use streaming and control capabilities.

Integration firm Hoang Minh Investment Technology Joint-stock Company – HMICO worked with university organizers to design and build AV solutions with Extron products. These are located in multiple laboratory spaces that support a variety of academic disciplines..

AV switching and distribution

The G building of the VinUniversity houses multiple laboratories with state-of-the-art technology, as well as several support rooms and meeting spaces.

The three laboratory floors offer a variety of studies, from engineering and robotics to anatomy and chemistry. Two of the largest incorporate a large number of display devices and an independent Extron AV switching and distribution matrix system.

A 16 HDMI switching array×8 DXP HD 4K Plus is the center of the anatomy lab and allows switching from multiple 4K/60 video sources to the lab's wall-mounted display devices.

Remote and rack-mounted sources inside the lab, together with display devices, are connected to the switching matrix using DTP transmitters and receivers to extend the signal in the 240 square meters of the room.

Control and audio of AV devices can be extended through the same twisted pair cable infrastructure used for 4K/60 video. The rack-mounted switching matrix also desembebe audio for integration with the sound system.

Extron transmitters and receivers enable optimal signal quality between the switching matrix and lab sources and display devices. Teams DTP HDMI 4K and on Extron DTP wall-mounted board send the 4K/60 HDMI source signals back to the switching array.

DTP extenders provide clean and simplified integration of control and audio of AV devices within the room. To support DisplayPort signals, the wall plate DTP T DWP 4K provides automatic switching between the two video inputs, simplifying operation.

An Extron 4K HDMI DTP receiver has been installed on every flat screen display device in the lab. Its reduced profile design allows it to be easily placed behind wall-mounted display devices.

The extension of 4K/60 video signals, Audio and control has been carried out with the convenience of DTP receivers and transmitters that can extend the signal up to 70 metre. These also support streaming HDCP encrypted content 2.3.

A gateway for ShareLink Pro collaboration 500 Extron facilitates wireless connectivity to instructor and staff from anywhere within the lab. Built-in support for a Mac or Windows laptop, as well as Apple and Android tablets and smartphones.

Connected using a USB adapter, the gateway's Miracast capability allows you to share content without having to install additional software.

ProDSP Processing

Hmico was concerned about acoustics due to the lab's extremely reflective surfaces.. The solution was the processor ProDSP DMP 128 bonus by Extron.

This 12 audio processor×8 was created to mix workstation and instructor microphones live with program audio, as well as to ensure clean audio for streamed and archived recordings.

An amplifier XPA U 1002-100V Rack-mounted Extron with switching matrix distributes audio to 16 ceiling speakers CS 26T Plus. This speaker model includes a transformer and tweeter with ferrofluid cooling dome mounted in the center of a paneled tweeter bridge that offers smooth off-axis response and wide 112° conical coverage..

These features also allowed for flexible speaker spacing to facilitate requirements within each lab..

XTP: research/study in engineering

To withstand the 400 square meters of the engineering laboratory, An Extron XTP system provides high-performance HDMI matrix switching and distribution via shielded twisted pair cable.

The modular switching matrix XTP II CrossPoint 1600 has been configured with 4K HDMI I/O cards and twisted pair. Input cards XTP II CP 4i HD 4K Plus and XTP CP 4i 4K support content from rack-mounted sources and those located inside the lab.

For the distribution of the control signal and AV by the 400 square meters of the laboratory, switching matrix includes output cards XTP HDMI and twisted pair. The XTP II CrossPoint model was chosen for its modularity, reliability and performance.

As technologies evolve, as higher resolutions, the switching array chassis remains in place, while XTP I/O cards can be changed to meet new requirements. This is both efficient and cost-effective for VinUniversity.

Extron XTP T HD 4K HDMI transmitters extend signals from lectern-installed sources to the switching array.

Output cards XTP II along with 12 Receptors XTP R HD 4K support multiple display devices at distances of up to one hundred meters. The AV system of this laboratory also supports wireless connectivity through the university's computer network using six gateways for collaboration ShareLink Pro.

Offering optimal sound quality, the engineering laboratory has been designed around the distribution of the Dante audio signal for possible scalability in the future.

Combines 14 audio interfaces AXI 02 At and an interface AXI 22 At, creating a sound system that leverages AES67 standards and the university's high-speed computing network for line-level audio distribution. An XPA 2002-100V audio amplifier distributes audio to 12 ceiling speakers CS 26T Plus, that ensure clear sound throughout the laboratory.

To make streaming easier in the lab, 12 SME 211 encoders send streaming content that can include different resolutions and bitrates.

Encoders provide independent streaming control, thus improving the flexibility of the system.

A media player VLC embedded in each student's computer software decodes the streaming of the units SME 211. An H.264 multimedia processor for streaming SMP 351 Extron records, simultaneously streams and stores content for later viewing.
