USB Power Delivery 2.0 introduced some changes to the way that power ratings between devices are handled, making the standard more flexible than before. The old set of Power Profiles were removed in PD 2.0 and replaced by Power Rules that allow for a wider range of current negotiations. The USB 3.1 specification adopted Power Profiles instead, but is only rated up to 15W rather than 100W.
PD 3.0 made some tweaks to enhance power delivery, but the Power Rules are the same as PD 2.0 products. Rules are split into four target power categories; 7.5W, >15W, >27W, and >45W; each of which offers a range of voltage and current configurations. Sources supplying more than 15 watts offer voltages of 5 and 9 volts, those supplying more than 27 watts offer 5, 9 and 15 volts, and those supplying more than 45 watts offer 5, 9, 15 and 20 volts. The maximum 100W power supply is achieved with 20V and up to 5A, although all of the other modes cap out at 3A, depending on the required power.
USB Power Delivery offers the following features:
• Increased power levels from existing USB standards up to 100W. • The power direction is no longer fixed. This enables the product with the power (Host or Peripheral) to provide the power. • Optimize power management across multiple peripherals by allowing each device to take only the power it requires, and to get more power when required for a given application. • Intelligent and flexible system-level management of power via optional hub communication with the PC. • It allows low power cases such as headsets to negotiate for only the power they require.
HDMI 1.4 supports a resolution up to 3840x2160 at 30 Hz and 1920x1080 at 120 Hz. At the same time, there is support for ARC, 3D, CEC management and more.
Note that HDMI 1.4 does not have the capability to support HDR.
HDMI 2.0 – Premium High Speed (up til 18 Gbit/s)
The product is ready and compatible with the newest version of Ultra HD with 4K 60 Hz support including HDCP 2.2, which is a technology for preventing illegal copying of 4K UHD content. Every piece of equipment in a setup must support HDCP 2.2 for a signal with this coding to pass through.
HDMI 2.0b – Premium High Speed (up til 18 Gbit/s)
The product supports 4K resolution and HDR (High Dynamic Range), which has a greater separation of color nuances, giving a wider pallette to colorize the image, and this resulting on more vibrant and lifelike colors.
HDMI 2.1 – Ultra High Speed (up to 48.0 Gbit/s)
There is support for resolutions up to 7680x4320 as well as HDR.
eARC was introduced with HDMI 2.1 but can be added to certain HDMI 2.0 products by firmware. eARC makes it possible to use a 7.1 surroundsystem and transfer lossless HD sound quality.
Power over Ethernet (PoE, EEE 802.3af-2003) is a cleber standard to supply ethernet connected devices, with power up to 15,4 Watt per PoE network switch port. The supply voltage are transmitted within the same ethernet cables as the data stream, and thereby only one CAT cable is needed, for e.g. IP cameras, Wi-Fi access points, door stations etc. The PoE standarden has been further developed into the PoE Plus/+ version (IEEE 802.3at-2009), which can delivery up to 25,5 Watt pr. connection, and are often utilized for HD network IP cameras.
Qi (pronounced/ CHEE from the Chinese word qi) is an open interface standard that defines wireless power transfer using inductive charging over distances of up to 4 cm (1.6 inches), developed by the Wireless Power Consortium. The system uses a charging pad and a compatible device, which is placed on top of the pad, charging via resonant inductive coupling.
Version 1.0 - 2010 up to 5 Watt Version 1.1 - 2012 up to 5 Watt Version 1.2 - 2015 up to 15 Watt
If you’re new to the concept of quick charging, the result is in the name: your smartphone charges up faster than it would without Quick Charge technology.
Qualcomm boasts a fourfold increase in charging times over conventional chargers with Quick Charge 3.0, up from the 40 percent speed increase offered by its first-generation technology. However, one of the interesting things to note is that Qualcomm isn’t touting massive increases in charging times over version 2.0, instead, the company is focusing on improved efficiency this time around.
Voltage • 3.6 V to 22 V, dynamic with 200 mV increments Max current • 2.6 A or 4.6 A Max power • 36 W (12 V x 3 A)
The major new feature with 3.0 is INOV (Intelligent Negotiation for Optimum Voltage), which allows for a fined tuned power output and a more optimized charging cycle. Firstly, different batteries require different charging voltages. Version 2.0 supported four modes at varying power levels, 5 volts/2amps, 9V/2A, 12V/1.67A, and a 20 volt option. Quick Charge 3.0’s INOV communicates with the device to request any voltage between 3.2V and 20V at 200mV increments, allowing for a wider selection of voltages.
Importantly, Qualcomm has retained backward compatibility with its 2.0 and 1.0 standards. As the power draw is handled on the smartphone side, you will safely receive the maximum amount of power for your device using any of the certified chargers. However, you won’t achieve full charging speeds if you try charging newer phones with older lower power chargers.
Although Qualcomm supports Quick Charge in all of its new SoCs, it is still up to smartphone and tablet manufacturers to implement the specific circuitry required to make full use of the fastest charging speeds available.
SuperSpeed USB 10 Gbps, also called USB 3.2 Gen 2, can handle up to 10 Gbit/s and is backward compatible with USB 3.2 Gen 1, USB 2.0, USB 1.1 and USB 1.0.
USB 3.2 Gen 2 has previously been called USB 3.1, but this name is no longer used.
USB4 is based on the Thunderbolt 3 protocol specification. It supports 20 Gbit/s throughputs, is compatible with Thunderbolt 3, and backward compatible with USB 3.2 and USB 2.0.
The architecture defines a method to share a single high-speed link with multiple end device types dynamically that best serves the transfer of data by type and application.
USB4™ identifies two transfer rates, USB4™ 20Gbps at 20Gbps and USB4™ 40Gbps at 40Gbps.
USB4™ Key Points: • Two-lane operation using existing USB Type-C® cables • Doubles the bandwidth to extend USB Type-C® performance • Up to 40Gbps operation over 40Gbps-certified cables • Enables multiple simultaneous data and display protocols • Multiple data and display protocols efficiently share the total available bus bandwidth • USB4™ hosts can optimally scale allocations for display data flow • Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
The USB4™ specification compliments and build upon the existing USB 3.2 and USB 2.0 specifications. The USB4™ architecture defines a method to share a single high-speed link with multiple end device types dynamically that best serves the transfer of data by type and application. As the USB Type-C® connector has evolved into the role of the external display port of many host products, the USB4™ specification provides the host the ability to optimally scale allocations for display data flow. Even as the USB4™ specification introduces a new underlying protocol, compatibility with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices is supported; the resulting connection scales to the best mutual capability of the devices being connected.

The Wireless Speaker & Audio (WiSA) Association is an industry group dedicated to implement wireless technology into stereo- and surround sound speakers, control boxes and televisions. The vision is to rid the installation of speaker wires and clunky AV receivers, while achieving quality audio and stable, synchronized connection.
WiSA can be freely adopted by any manufacturer who wishes to do so. Among the first movers are Klipsch and B&O. Now also TV manufacturers are also beginning to implement WiSA wireless sound directly in flatscreens, making it easy to connect active wireless Hi-Fi WiSA speakers to the TV without cables.
