USB, THE FOURTH

The USB standard has a long and eventful history. Now USB 4 promises to bring clarity to the specification chaos and simplify the use of cables and devices.

Since its introduction in 1996, Universal Serial Bus, or USB for short, has established itself as a universal and indispensable IT interface for all computer peripherals. Many of the previously existing peripheral interfaces have long since become history (ADB, PS/2, SCSI, LVD, IEEE 1284, etc.). Others, such as RS-232, now only have a niche existence in the industrial sector. Throughout the 23 year history of the USB interface there have been many hurdles and obstacles, but potential competitors such as Firewire, which was supposed to correct some of USB’s weaknesses, have simply been pushed out of the market by the sheer ubiquity of USB. Others, such as Thunderbolt, are now part of USB 4.

USB Success Story

The development and release of USB 1.0 was based on the idea of creating a way to connect computer peripherals using one standardized port. What today appears to be a matter of course was then a futuristic idea because of the multitude of different interfaces then in use. These were all replaced by USB. Key factors in the reason for USB’s success were new ideas such as Plug & Play, the support for hot-plugging devices, ease of use, and data transfer rates of up to 12 Mbps, which were quite high at the time.

The USB connector has changed several times over the decades.

USB technology has undergone multiple developments throughout its lifespan. Version 1.1 brought corrections to minor specification errors; In 2000, USB 2.0 increased the transfer rate to 480Mbps, USB 3.0 arrived with a 5Gbps data rate and new extended connectors. These advancements were built upon further by USB 3.1 in 2013, which has a data rate of 10Gbps, and USB 3.2 with 20Gbps at the end of 2017. This constant increase in data transfer rates has enabled potential USB competitors to be pushed out of markets, or at least kept in check, with only time-critical, niche applications using other standards.

Lightning and Thunderbolt

From 2011, however, a new system appeared on the scene: Thunderbolt. Mechanically and electrically engineered based on the DisplayPort (DP) technology standard and designed by Intel in cooperation with Apple. Thunderbolt extended DisplayPort, a pure AV interface, by adding a bidirectional data channel based on PCI Express.

Thunderbolt uses active electronics in its connectors, hiding the physical layer from the host and devices. The first two versions of Thunderbolt used a specialist DP connector, the Mini-DP connector introduced by Apple. However, Thunderbolt 3 then adopted the USB connector type C, which was introduced alongside USB 3.1. USB C can be connected regardless of orientation and was miniaturised even further.

With initial speeds double that of USB 3.0, Thunderbolt was a serious competitor to USB from the beginning. However, due to the market spread of USB and the much cheaper hardware that could be produced for this standard, Thunderbolt failed to gain any meaningful gains over USB.

Turning Two into One

At the beginning of 2019, Intel and the USB Implementers Forum (USB-IF) announced the transfer of the protocol specifications from Thunderbolt to the USB-IF. Towards the end of the 3rd quarter of 2019 the convergence was completed with the newly published standard, USB 4 (Enhanced Superspeed), which combines the best of both worlds under the guise of USB. Thunderbolt gave the new specification a maximum transmission speed of 40 Gbps – twice as fast as the USB 3.2! USB, on the other hand, contributed the tree structure of the entire system made possible using hubs, because Thunderbolt devices could previously only be connected in a chain.

The transmission speeds have massively increased over the generations.

USB has become a great deal more complex now that it must incorporate the bidirectional PCIe protocol inherited from Thunderbolt 3 in addition to the Enhanced SuperSpeed signals. It must also be able to handle the DisplayPort Alternate Mode for AV transmission, which has been possible with Thunderbolt since the beginning and with USB since version 3.1. Moreover, it must still maintain USB 2.0 protocol support for downward compatibility.

The whole and the sum of its parts

That’s a whole lot of different protocols! So that USB 4 host adapters and hubs can handle them all, they contain a USB Enhanced Superspeed host, USB 2.0 hosts or hubs, a PCIe controller or switch and a DisplayPort adapter as internal modules. The interaction between these modules is controlled and coordinated by a further internal component in each of the hosts, hubs and devices, called the router.

With USB 4, the Type C connector will become the standard.

The Type C connector has been retained from USB Version 3.1 and TB3. It was introduced in the wake of USB 3.1, but independently of it, and enables alternate mode: switching from pure USB or Thunderbolt data output to DisplayPort signals. The wire pairs intended for data transfer are then used completely or partially for the transfer of AV data. Thus, not only peripheral devices, but also monitors and projectors can be connected.

USB 4 allows a maximum of 40 Gbps as defined for TB3 specifications, but it is less binding to that specification. This means that USB 4 does not necessarily have to be fully downward compatible with Thunderbolt 3 devices. These will run on any USB 4 host, but at a reduced speed of 20 GBps. Users will need to take a close look at what’s possible when buying hardware. Whether a USB 4 host can deliver the full 40 Gbps or not will probably be a question of cost, at least for first one or two generations of host adapters available on the market.

Naming conventions simplified

The designation scheme used since USB 3.1 needs some getting used to. Before this version, the speeds were directly assigned from the USB version number (USB 2.0 with 480 Mbps, USB 3.0 with 5 Gbps), but since version 3.1 one had to take a closer look.

The symbols for USB and Thunderbolt standard

With the introduction of USB 3.1…

  • USB 3.0 with 5 Gbps was identified as USB 3.1 Gen 1 (Gen for Generation)
  • USB 3.1 with 10 Gbps was known as USB 3.1 Gen 2

With the introduction of USB 3.2…

  • USB 3.1 Gen 1 with 5 Gbps was now called USB 3.2 Gen 1 (It uses a Gen 1 wire pair with 5 Gbps)
  • USB 3.1 Gen 2 with 10 Gbps is now called USB 3.2 Gen 2 (It uses a Gen 2 wire pair with 10 Gbps)
  • USB 3.2 with 20 Gbps is called USB 3.2 Gen 2×2 (because it uses two Gen 2 wire pairs with 10 Gbps each)

You can see how this naming scheme becomes visible: each new USB version contains the previous ones and distinguishes the data rates by the corresponding ‘Gen’ version. Whether this scheme will continue with USB 4 and whether the older 3.x versions will be adapted by name is not yet clear, but the following is certain:

  • USB 4 with 40 Gbps is called USB 4 Gen 3×2 (because it uses two wire pairs of the new Gen 3 with 20 Gbps each)
  • USB 4 with 20 Gbps is called USB 4 Gen 2×2 (because it uses two pairs of wires of Gen 2 with 10 Gbps each)

Full takeover: Power Delivery

The latest version of the Standard Power Delivery, which negotiates and regulates the power supply between host, hubs and devices both under USB version 3.1 Gen 2 and higher and under Thunderbolt 3 (i.e. all versions using the type C connector), has been completely adopted in USB 4.

Profiles of voltage and current (5V/2A, 12V/1.5A, 12V/3A, 20V3A or 20V/5A) and supply direction are negotiated. All cables that can withstand more than the 1.5A provided for the profile with the lowest current load must announce this via a so-called e-mark chip so that the correct profile can be negotiated.

This makes it possible, for example, to connect a power supply unit with a USB type C plug to the PD-enabled USB port of a hub or docking station and connect it to a notebook via a single USB type C cable. With the right equipment, the peripherals are now clearer and the cable clutter on the desk is significantly reduced.

What does all this mean for the user?

USB 4 and the merger of USB with Thunderbolt are nothing more than the implementation of market requirements for higher bandwidths as well as uniform and universal standards. The implementation for the transfer of 40 Gbps and the unification of the two standards under the umbrella of USB is a decisive step.

Once USB 4 is fully established in the market, and provided that the user owns those USB devices that support full USB 4 functionality, life with USB will probably become easier. In the medium to long term, there will only be one type C connector for all peripherals. Devices with other connectors will eventually disappear or require the use of an adapter.

Until then, however, buyers are forced to keep their eyes open and take a very close look at the manufacturer’s specifications regarding the speed (Gen-Postfix for the USB version) and PD capability of the individual components of the hardware they wish to purchase.

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.

The LINDY Guide to USB 3.1

WHAT IS USB 3.1?

USB 3.1 is the new standard of USB connection technology. The USB 3.1 standard includes a  number of new features, most notably SuperSpeed+ or Gen2 data speed. SuperSpeed+ allows USB 3.1 to transfer data at a speed of 10 Gbps. This means USB 3.1 can transfer a year’s worth of music in just 10 minutes or a Full HD movie in just 30 seconds. The new standard also allows USB 3.1 to provide power delivery, alternate video mode and data transfer through a single cable.

REVERSIBLE

At the same time as the new USB 3.1 standard, the new reversible Type C connector was also developed. This connector comes with many new features, the main benefit being that it is now reversible so no matter which orientation the cable is inserted, you will always find a connection. This new technology allows a fully bi-directional cable with automatic Host and Device negotiation.USB 3.1 Type C Reversible Connector

THE DIFFERENCE BETWEEN USB-C AND USB 3.1?

USB 3.1 and USB-C, though developed concurrently, are not the same thing. USB 3.1 is an upgrade over the older USB 2.0 and USB 3.0 technology. USB 3.1 allows faster data transfer in comparison to these two previous versions. USB 3.1 is a new USB technology whilst USB-C is a connector which facilitates this technology.

USB 3.1 POWER DELIVERY

USB Type C cables support 20V 3A (60w) of power, however a new charging standard named PD (Power Delivery) has been released which can offer up to 100w (20V at 5A). New cables are required to take advantage of this technology and these use an embedded chip (e-marker) to manage power control, while still providing the SuperSpeed+ 10Gbps
data link and backwards compatibility.USB 3.1 Power Delivery

USB 3.1 Power Delivery provides different rules for supplying power. The rules are automatically recognized and negotiated between the host, cable, and device. These systems require the use of active cables to allow the devices to “communicate” which rule is suitable and protect against overload.

USB 3.1 power delivery is not only suitable for notebooks but also other professional devices with a power consumption of up to 100 watts. PD can be maintained even when the USB-C connection is being used for data transfer, video or Ethernet.

USB 3.1 ALTERNATE MODE

Provides up to 100W, 5Gbps USB data transfer rates, and the simultaneous transfer of 4K video and audio data.

By using the Type C connection USB 3.1 also allows an alternate mode for additional functionality. This allows features like DisplayPort, HDMI, MHL or Thunderbolt. Please note however that the Host and Device must both support the same alternate mode.

DisplayPort Alternate Mode supports resolutions up to Ultra HD 4K 3840 x 2160. Alongside Simultaneous 4K Video & 5Gbps transfer rates.

USB 3.1 Alternate Mode

IS USB 3.1 BACKWARDS COMPATIBLE?

USB 3.1 now supports up to 10Gbps speeds whilst remaining backwards compatible with the previous 5 Gbps (USB 3.1 Gen 1 / USB 3.0) and 480Mbps (USB 2.0) standards. USB 3.1 Gen 2 also works with existing USB 3.0 connections thanks to the improved encoding method used to transmit data.

Type C has been designed in such a way it is able to operate with legacy connections via an adapter or converter cable. However not all features are available unless you use Type C on both ends.USB 3.1 Backwards Compatibility

HOW DO I RECOGNISE A USB 3.1 CABLE?

The connector for USB-C is slightly smaller than previous USB standards and looks similar to a Micro-USB connector.

USB 3.1 Connector Types

WHERE WILL I FIND 3.1 TYPE C?

Most new mobile phones, tablets and laptops are now supplied with a Type C port whether it’s for charging or data transfer. One big advantage is that you no longer have proprietary chargers and you can use one charger for all your devices. USB Type C was originally used on Notebooks and in the tablet phone market before filtering through to more mainstream devices.

USB 3.1 Devices

IS THUNDERBOLT THE SAME AS USB 3.1?

Thunderbolt is the connection and power delivery technology used by Apple to charge and deliver data to their products such as Macbooks and iMacs. USB-C is now the connector that is used with the latest Thunderbolt 3 technology. This allows Thunderbolt and USB-C to combine for an amazing 40Gbps of bandwidth. Thunderbolt 3 also uses the Type C port, however this port also offers additional functions that require specific Thunderbolt 3 Type C cables.

Using Thunderbolt 3 a single USB-C port can deliver power in both directions. So a port can charge a device or, alternatively, be charged by one. USB-C and Thunderbolt are capable of delivering up to 100 watts of power, so a single cable can be used to connect to a dock, or display, whilst your Apple device is charged simultaneously.

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.

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

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 Gives Devices the Charge They Deserve

Devices that are hungry on power can make charging with a USB multi-plug frustrating since many won’t supply the current required if more than one device is connected. The end result is often the most demanding devices such as an iPad don’t actually charge, even when left overnight. LINDY’s latest travel adapter solves this issue by specifying the ports that supply the higher charge.

The LINDY USB Mains Travel Charger allows users to charge up to 4 devices with a combined maximum output of 5A at one time. When four devices are connected that require more than 1A, the device connected in the first USB port will take the maximum output it needs up to 2.5A, then the next, and so on. By connecting the devices that take the most charge in descending order, the LINDY charger ensures that all devices are charged and ready for use in as short amount of time as possible.

“It can be so frustrating on holiday to put your devices on charge before you go to bed, only to find in the morning that most of them are still showing the battery symbol in the red,” says Tony Jamieson, General Manager of LINDY Australia. “Our latest charger allows users to choose which devices get the maximum power, while replacing the need to take several different chargers on holiday, making more room in the suitcase for other essentials.”

Suitable for use with most USB powered devices including tablets, MP3 players, mobile phones etc, the LINDY USB Mains Travel Charger has over current, over voltage and short circuit protection and includes adapters for use in UK, Europe, USA and Australia.

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.
