FAQ (Frequently Asked Questions)
(1) What is HDMI 2.0?
HDMI 2.0, which is backwards compatible with earlier versions of the HDMI specification, significantly increases bandwidth up to 18Gbps and adds key enhancements to support market requirements for enhancing the consumer video and audio experience.
HDMI 2.0 significantly increases bandwidth to 18Gbps and includes the following advanced features:
Resolutions up to 4K@50/60 (2160p), which is 4 times the clarity of 1080p/60 video resolution, for the ultimate video experience
Up to 32 audio channels for a multi-dimensional immersive audio experience
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
(2)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). (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.
(3)What's the difference between USB 1.1, USB 2.0 and USB 3.0?
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. 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.
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.
