Long Distance Signal Extension with Multiple Technologies in the Home

The modern home is becoming a technology hub with devices in constant communication across multiple rooms. Centralised signal management has become a large part of the home technology experience. As more devices are added, further away from this central location, cost-efficient and versatile extenders become necessary. This scenario explores the use of four differing extension technologies from Lindy, including powerful fibre optic extenders, to distribute signals up to 300m in residential environments.

Modern residential buildings often feature multiple displays and media sources that use a variety of media signals to transmit audio and video across longer distances as annex or out-buildings become more popular.

In this example four sources are controlled and distributed by a central matrix around a home and to an out-building. The four sources are connected via HDMI cables to a local 4×4 Matrix Pro which then outputs the four signals using different transmission methods for signal extension over a variety of distances. This matrix supports 4K 18G inputs and outputs to ensure that, if the source permits, the entire solution can utilise the full 18G bandwidth capacity of the latest HDMI standards.

In this scenario the matrix outputs to four different transmission technologies. The first, and simplest, of these is a standard local HDMI cable that is provides the 4K connection directly over short distances to a local display. Using audio extraction, the audio signal is first routed to an amplifier before the TV so that a speaker system may be used inplace of the TV’s integrated speakers.

The second output from the matrix is transmitted via an 18G active HDMI cable to a room close to the location of the matrix. The third output passes through a 100m HDMI over CATX extender system. The transmitter unit is connected to the matrix by a simple HDMI cable before the signal is sent along inexpensive CATX cable to the receiver unit which is upstairs/some  distance from the matrix. This receiver is placed close to another 4K display which the signal is finally sent to via HDMI cable.

The fourth, and final, output from the matrix is sent to an out-building, annex, pool area etc. via a fibre optic extender system that features both transmitter and receiver units. By using fibre optic cables to make this connection, large distances up to 300m can be covered using cheap, efficient and easy-to-install duplex fibre optic cabling. This method of signal transmission benefits from EMI & RF resistance so that other electrical cables or equipment located nearby don’t cause artefacts or errors in the transmission. The fibre optic connection allows IR signals to be sent to the display for remote control of the source while also delivering the full 18G bandwidth with no compression, ensuring content arrives at the display exactly how it left the source.

InfoComm Webinar powered by LINDY: Overcoming the Limits of HDBaseT – Lossless Compression and HDBaseT

HDBaseT is an ideal solution for simplified, high performance signal distribution while eliminating cable clutter. However, HDBaseT currently faces two limitations: the 100m maximum transmission distance and the 8Gbps bandwidth that allows resolutions of 4k 4:2:0.

Integrators are patiently awaiting the release of HDBaseT 3.0. In the meantime, two new HDBaseT advances have been made that overcome the limitations of the current HDBaseT technology. Lindy will demonstrate these advances in this webinar.

The first of these advances is the introduction of a lossless compression that supports a higher bandwidth and allows 4K 60Hz 4:4:4 video signals with very low latency. The second is HDBaseT over IP, which allows the extension of HDBaseT over 100m. Additionally this advance allows you to leverage existing pro-AV installations and interfaces to achieve cross-floor and cross-building AV sessions.

What will you learn in this webinar:
– How to overcome the current HDBaseT bandwidth limits to achieve 4K 60Hz 4:4:4 resolution.
– How to approach and integrate lossless compression in a project
– Understand whether OverIP transmission technology is suitable for your installations.

DEPLOYING A VIRTUAL TV STUDIO WITH A LINDY MODULAR MATRIX SYSTEM

THE PROJECT: CREATING A STATE-OF-THE-ART PRO AV INSTALLATION FOR SKY TV

The demand for professional audio video signal management solutions is increasing dramatically as complex AV installations become commonplace at events, trade fairs, conferences, airports and shopping centres. The field of broadcasting has been at the forefront of developments in AV signal management. Modern broadcast studios now use sophisticated AV technology such as video projection, 3D mapping and elaborate content management systems to create ‘virtual TV studios’ where almost anything is possible including seamless and on the fly production.

Sky’s TV Studio 6 in Milan has recently undergone an upgrade programme to include the latest in professional AV technology. The studio was equipped with this technology by the AV technology solutions company Events on Stage (EoS). The project was led by Marco Landini who was able to hand over a completely new studio with modern AV systems in just one week.

REQUIREMENTS PROFILE: HIGH PERFORMANCE, RELIABLE COMPONENTS FOR MAXIMUM FLEXIBILITY IN SIGNAL MANAGEMENT

The new studio was designed to be enclosed on three sides by 50m projection screens to provide a dynamic and interactive background for different programs. To ensure uniform and continuous projection, six projectors were used and the Dataton Watchout presentation system was selected and installed on 10 media servers to provide multi-display projections.

“Because of the challenges of working within the TV environment, and the complexity of the installation, it was vital that the solution would be 100% reliable and without any failures. All devices were chosen from a narrow range of specialist manufacturers with a reputation for high quality, reliable solutions and excellent customer service” explains Landini. “Lindy’s modular matrix solution was chosen because of its flexibility and reliability, allowing users to combine the input and output of HDMI, DVI, VGA, or HDBaseT signals to Ultra HD resolution displays.”

SOLUTION: POWERFUL, VERSATILE & COST-EFFECTIVE AV SOLUTIONS

The heart of the AV system is the 32 x 32 Modular Matrix from Lindy. This modular matrix solution makes it possible to combine different signal sources and distribute them to each display device. Built-in redundancy provides the highest possible reliability in the event of any unexpected failures, both in the matrix itself and in the inputs and outputs to the sources and projectors.
The new studio also uses two mapping projectors from Panasonic that were installed perpendicular to the floor and are used for projections on horizontal surfaces such as consoles. The projectors function interactively by using capacitive sensor systems that are connected to the transmission software.
Everything within the installation is controlled by software from EoS, which allows the end user to monitor the condition of each device in real time. To compliment this software a closed system of Panasonic HD cameras allow images to be monitored from the production control room.
“The versatility of such a studio not only increases the flexibility in practical use, but also reduces the production costs as stage designs and background scenery become unnecessary to construct and store” explains Landini.

The Difference Between Audio Extractors and ARC Extractors Explained

We often find that there is some confusion between what an HDMI Audio Extractor or De-Embedder is capable of, and what ARC is used for with HDMI equipment. In this blog we will be discussing the differences in function for the linked products below, and where they would generally be used.

38068 – HDMI 4K ARC Extractor with HDMI Pass-Through & CEC Emulation
38097 – HDMI 4K Audio Extractor De-Embedder with ARC & MHL

Within the HDMI standard there is an optional feature known as the Audio Return Channel, which is usually referred to as ‘ARC’. Television manufacturers will often implement this into their products in place of a headphone, optical SPDIF or digital coaxial port, this however limits what type of speakers a user can then connect.
The aim of ARC is to reduce the number of cables between a TV and AV receiver or speaker system; this is not always suitable for older equipment which may not natively support ARC. It is in this scenario where you would use our Part No. 38068, designed for ARC enabled TVs and is perfect for sending the audio from your TVs inbuilt tuner or apps such as Netflix to Optical sound bars or AV systems.
Using an HDMI cable from the HDMI ARC port on your TV to the HDMI OUT port on the 38068, this product will allow an audio signal to travel from your TV back down the HDMI cable to the ARC extractor where it will be sent out to the Optical SPDIF OUT port. Our extractor also has the additional feature of HDMI Pass-Through; this means you can still connect a source device such as a Blu-ray player or Foxtel box, without losing one of the HDMI ports on your TV. When ARC is disabled using the button on the unit, audio can travel from your source device, through the extractor to your TV as normal.

Below is a diagram showing a typical set-up with our 38068 HDMI Arc Extractor:

38068-Diagram

When you have a source device such as a bluray player or sky box, and want to send the audio from these devices to your sound bar, headphones or AV system, we would recommend an Audio Extractor. Rather than taking the sound from your TVs ARC HDMI port, it will take the audio from any HDMI source. This audio is duplicated and can then be sent out to either RCA, headphones/speakers, or to a sound bar / AV system using Optical SPDIF. The video will then carry on to your TV as normal. Should your phone support it, our 38097 Audio Extractor also has the additional function of MHL, allowing you to mirror your phone screen onto your TV. The unit also supports ARC, and works in a similar way to the 38068 but with the added benefit of extracting audio directly from the source as well as from the ARC enabled TV.

LINDY Launches Cost Effective Extender for HDMI Over Gigabit Network

Halves the cost of equipment required to broadcast HDMI signals over IP

Here is our most cost effective product yet for distributing video content throughout large buildings such as schools, hotels, hospitals, shops, shopping centres and business premises. The LINDY HDMI Over IP Extender allows for full HD images to be sent over a gigabit ethernet network or up to 100m using a single CAT6 Cable.

Consisting of transmitter and receiver units, the extender can support one to one, one to many and many to many configurations. In addition, it is possible to use up to three layers of active network devices to distribute video making it highly flexible for digital signage, presentation and demonstration applications, while providing the ability to expand easily as the installation evolves.

“Our latest product cuts in half the cost of equipment required to broadcast HDMI signals over IP,” says Owen Haigh, Senior Product Manager of LINDY Electronics. “Sold as individual units, organisations need only purchase the transmitters and receivers required for their specific configuration.”

Using a form of video compression that is barely perceptible, the LINDY HDMI Over IP Extender converts the HDMI signal to enable it to be broadcast over IP. LINDY suggests because of high use of bandwidth requirements of Full HD video that the system runs on its own dedicated network or used in a separate port based VLAN.

The LINDY HDMI Over IP Extender Transmitter (part no. 38127) and the LINDY HDMI Over IP Extender Receiver (part no. 38128) can be purchased from www.lindy.com.au

HDMI over IP Video Wall Extender

LINDY Launches Ethernet Extender for Video Walls

We are pleased to announce our new HDMI over Gigabit IP Video Wall Extender which allows you to distribute an HDMI signal up to 1080p via RJ-45 cable up to 100m or through an Ethernet network to multiple displays. Perfect for digital signage, public display and large scale presentations these extenders convert the HDMI signal to IP broadcast signals. Network devices can be used to distribute the signals.

The LINDY HDMI Video Wall over IP Extender supports arrays of up to 64 screens in an 8 by 8 configuration. An intuitive web GUI enables full, local or remote control over how the content is displayed along with essential control over bezel correction and video tearing.

In addition to the video wall configuration, the extenders support 1-to-1, 1-to-many and many-to-many installations, for extending and distributing signals over extremely long distances. Transmitter and receiver units can be purchased separately to give maximum flexibility.

USB 3.0 to HDMI Adapters

New 4K Adapter and Updated HDMI Adapter Connects Monitors Via USB 3.0

We now have two great ways to connect high-end monitors via a computer’s USB 3.0 port, without the hassle of adding a suitable internal graphics card.

The LINDY USB to 4K DisplayPort Adapter enables users to connect a 4K Ultra HD monitor by simply installing the driver and connecting the adapter to the computer using the supplied USB 3.0 Type A to Micro-B cable. Once installed the 4K monitor can be connected to the adapter using a normal DisplayPort cable. The adapter supports 4K resolutions up to 3840 x 2160 @30Hz and includes the ability to transfer audio from the computer to the monitor.

The LINDY USB 3.0 to HDMI Adapter allows users to display Full HD 1080p video and graphics on their TV, monitor or projector via their computer’s USB 3.0 SuperSpeed port. Connected in a similar fashion as the 4K DisplayPort Adapter above, the converter supports resolutions up to 1920×1200, including 1080p. This latest adapter is a newer version of a previous model and is now available at a lower cost.

“While installing an internal graphics card into a computer is a relatively simple process, it’s not something everybody feels confident in doing, particularly when it’s just to connect a monitor temporarily,” says Andrew Ingram, Product Manager of LINDY Electronics. “Our new adapters allow users to connect the very latest high resolution monitors quickly and easily. They are ideal for laptop users that often challenged with different connection options everywhere they go, as well home users who just want to add another screen to their set-up.”

Both the LINDY adapters allow monitors to be used for primary, mirrored or extended desktop. They are bus powered and therefore require no addition power, have a compact design making them east to carry and store and are guaranteed for 2 years.

LINDY Switch Makes Multifunction Display Easy

User friendly GUI gives business users control over their displays

We announced today a video switch for businesses that don’t have the support of an AV technician, but want to show multiple displays to a single screen and provide additional information such as details of special offers or rolling news.

The LINDY 4 Port HDMI Video Processor Switch takes the output from four HDMI sources and displays them in a myriad of combinations on a single display. Using a simple desktop publishing style web interface, users can easily alter the way images are displayed, making it extremely flexible for a variety of uses from the foyer to the board room.

“The video processor uses chroma key to overlay two images, something that most people associate with the green screens in film production or TV weather reports, but it’s a highly effective tool in many other situations,” says Owen Haigh, Senior Product Manager of LINDY Electronics. “Chroma key allows users to easily overlay text or images over another HDMI source making it ideal in situation where information frequently changes. The user friendly GUI means that you don’t need to be an AV expert to get the results you want.”

In addition to chroma key, the LINDY 4 Port HDMI Video Processor Switch allows for images to be shown in Picture in Picture (PiP) and multi-window displays, supporting resolutions up to 1080p, which makes it ideal for control, monitoring and security applications. It is also capable of mirror and rotate functions. Audio is provided through the independent audio channel selection that supports a number of audio outputs including AC3, Dolby TrueHD and DTS HD. The switch can also be controlled through on-panel controls, IR remote, RS 232 and Telnet.
