Up to 1536kHz audio sample frequency for the highest audio fidelity

Simultaneous delivery of dual video streams to multiple users on the same screen

Simultaneous delivery of multi-stream audio to multiple users (Up to 4)

Support for the wide angle theatrical 21:9 video aspect ratio

Dynamic synchronization of video and audio streams

CEC extensions provide more expanded command and control of consumer electronics devices through a single control point

What's SlimPort?

SlimPort, a brand of Analogix products, complies with Mobility DisplayPort, also known as MyDP, which is an industry standard for a mobile audio/video Interface, providing connectivity from mobile devices to external displays and HDTVs. SlimPort implements the transmission of video up to 4K-UltraHD and up to eight channels of audio over the micro-USB connector to an external converter accessory or display device. SlimPort products support seamless connectivity to DisplayPort, HDMI and VGA displays. The MyDP standard was released in June 2012, and the first product to use SlimPort was Google's Nexus 4 smartphone.


SlimPort is an energy-efficient alternative to Mobile High-Definition Link (MHL). While MHL adapters require external power, SlimPort does not require external power or extra cables, and draws no power from the source to operate.

Q: what products could support MHL?

Silicon Image announced a family of chips supporting MHL including a transmitter, a bridge and a port processor.

LG Electronics available on December 4, 2011 AT&T Wireless and LG Electronics Nitro HD (AT&T) / Optimus LTE (LTE carriers), a True HD AH-IPS panel display on the device with MHL output abilities for any TV equipped with HDMI input.

Samsung announced at the 2011 Mobile World Congress that their Galaxy S II mobile devices feature MHL connections.

 HTC announced at the 2011 CTIA that their 'EVO 3D' mobile device supports MHL output and in addition that the HTC 'Sensation' will also have this capability, as well as its successor, the 'Sensation XE'. The HTC Rezound, which is a sister device to the Sensation XE also has the MHL port.

Roku unveiled the 'Roku Streaming Stick' on January 4, 2012 in an official blog post entitled 'There’s a Better Way to Build a Smart TV'. The Streaming Stick is said to include everything comprised in a Roku player—built-in WiFi, processor, memory and software—and will deliver all the channels found on the Roku platform today.[18]

Q: What is MHL?

Mobile High-Definition Link (MHL) is a proposed industry standard for a mobile audio/video interface for directly connecting mobile phones and other portable consumer electronics (CE) devices to high-definition televisions (HDTVs) and displays. The MHL standard features a single cable with a low pin-count interface able to support up to 1080p high-definition (HD) video and digital audio while simultaneously charging the connected device.
MHL is being developed by the MHL Consortium, a consortium of developers of mobile devices.


The HDTV provides power to the connected device.
Uses a single, thin cable to connect the mobile device to the HDTV.
The HDTV remote will control the connected device with guaranteed mixed manufacturer interoperability (CEC).[1] (also see Silicon Image's press release about MHL on December 14, 2010). Note: The built-in RCP (Remote Control Protocol) function allows you to use the Remote Control of HDTV to operate the MHL mobile device through HDTV’s CEC function.
1080p uncompressed HD video.
8 channel (e.g., 7.1 surround sound) uncompressed audio.
Supports High-bandwidth Digital Content Protection (HDCP).
MHL is connection agnostic (i.e., not tied to a specific type of hardware connector). The first implementations dual-purpose the most popular mobile connection (micro USB) and the most popular HDTV connection (HDMI). Other than the connectors being used, no USB nor HDMI technology is being used. It is exclusively MHL signalling through the connectors and over the cable. Other proprietary and custom connections are also allowed.
By transporting the digital content in digital form, the full impact of the picture (whether still images or video) can be seen on HDTVs.


Q: What's the difference between USB 1.1, USB 2.0 and USB 3.0?

USB 1.1
The Universal Serial Bus is the most widely deployed PC peripheral interface in history, enabling simple plug and play connectivity for a wide variety of devices to enhance the computing experience. Developed to improve ease of use and provide flexible port expansion, the USB bus has become an indispensable computing technology. USB 1.1 provides support for two interface speeds: Low Speed at 1.5Mb/s and Full Speed at 12Mb/s. The two interface speeds target specific classes of devices to provide the most efficient and cost-effective interconnect solution. Low speed devices are typically interactive input devices such as keyboards, mice or game controllers. Full speed devices are typically application specific input devices such as microphones, cameras and printers. Despite the introduction of USB 2.0 and 3.0, USB 1.1 is still a very viable and usable option, depending on your application and speed requirements.

USB 2.0
The Universal Serial Bus is the most widely deployed PC peripheral interface in history, enabling simple plug and play connectivity for a wide variety of devices to enhance the computing experience. As PC’s and peripheral devices have added more processing bandwidth, performance and features, the USB 2.0 standard was developed to offer a complimentary high-speed transfer rate at 480Mb/s. Backwards compatible with the full speed and low speed transfer rates of USB 1.1, USB 2.0 delivers a significant bandwidth increase while maintaining the value added features that motivated the original USB development.

Super Speed USB 3.0
As technology innovation marches forward, new kinds of devices, media formats, and large inexpensive storage are converging. They require significantly more bus bandwidth to maintain the interactive experience users have come to expect. In addition, user applications demand a higher performance connection between the PC and these increasingly sophisticated peripherals. USB 3.0 addresses this need by adding an even higher transfer rate to match these new usage and devices. USB continues to be the answer to conncectivity for PC, Consumer Electronics, and Mobile architectures, It is a fast, bidirectional, low-cost, dynamically attachable interface that is consistent with the requirements of the PC platforms of today and tomorrow. SuperSpeed USB brings significant performance enhancements to the ubiquitous USB standard, while remaining compatible with the billions of USB enabled devices currently deployed in the market. SuperSpeed USB will deliver 10x the data transfer rate of Hi-Speed USB, as well as improved power efficiency. ? SuperSpeed USB has a 5 Gbps signaling rate offering 10x performance increase over Hi-Speed USB. ? SuperSpeed USB is a Sync-N-Go technology that minimizes user wait-time. ? SuperSpeed USB will provide Optimized Power Efficiency.No device polling and lower active and idle power requirements. ? SuperSpeed USB is backwards compatible with USB 2.0. Devices interoperate with USB 2.0 platforms. Hosts support USB 2.0 legacy devices. The USB 3.0 SuperSpeed specification has been ratified. The SuperSpeed specification provides the technical details to understand USB 3.0 requirements and design USB 3.0 compatible products and is available for download from the official USB website at Check our MilesTek’s complete line of USB products,
