Best Hdmi Cables 2017

In today’s digital age the ability to transmit video signals and high-definition audio using a single cable it is not only technical innovation, but also a necessary tool for the consolidation of a mess, thanks to the ever evolving home entertainment. HDMI cable-best friend, technical guru, if we are talking about the extortion of the TV and speaker settings in the home.

HDMI means High-Definition Multimedia Interface and is the first uncompressed, all digital interface designed for the simultaneous transmission of audio and video signals using a single cable. HDMI is backward compatible with digital video interface , which was originally developed to improve the quality of old flat LCD monitors and modern graphics cards. HDMI is the standard cable for use with most modern HD TVs, Blu-ray players, digital video recorders, new computers and video cards. Both cables and HDMI ports easy to use and connect to the equipment in the same way as USB cables. HDMI cable supports plug-and-play, which means that provides superior signal quality with minimal effort during the configuration process.

HDMI cable uses short signaling differential transition to transfer information from one place to another. Consider TMDS as a way zakodowywania signals of travelers, to protect them from degradation when delivered to home theater (e.g. DVD Player and TV). This technology provides the highest quality picture and sound from connected devices. To protect your information from piracy of data during transport, the cable Protocol is used in verifying digital copy protection high-bandwidth. This Protocol allows both the source device (e.g. DVD Player) and the receiving device (e.g. another television) to communicate with each other using the authentication keys.

Each device home theater system includes identification data and encryption data stored in its expanded chip identification information . The source encodes the user data using a unique authentication key, which the receiving device decodes, using the same information. In this sense, the source checks the validity of the authentication key receiving device that allows you to view the TV video and audio cable. This process is called handshakepomiędzy the source device and receiving and happens almost instantly in the HDMI cable. If disabled, the device will attempt to intercept the data source, the termination of data transmission. During this process, the source checks whether the authorization key has not changed.

Several iterations of HDMI was released in 2002, since HDMI 1.0 to version 2.0, each of which has its own progress against its predecessors. However, all use the same cable and connector, with small differences in shape and size. The most advanced features now include optional support for 3D and Ethernet.

As in the case of DVI, the HDMI cables use the some connector pins to ensure signal transmission data over twisted pair copper wires. Currently, there are several types of HDMI connectors, depending on the device and circumstances, of which the latest is the cable micro-HDMI (type D) released with version 1.4 interface.

Choose your cable Wisely
Length and strength is the first issues to keep in mind when planning the purchase of a HDMI cable. More in length they are usually a bit more expensive, but may be required depending on configuration home theater system. He said that you don’t have to break the Bank to get a cable of good quality. The longest HDMI cables have a length of up to fifteen meters. At this point can be a weakening of the signal , but it depends also from the manufacture of the cable components.

If you have a TV capable of displaying 4K or you are interested in one of them, it is important to make sure that the HDMI cable, which you drive has a maximum data volume that can process the signal of high quality.

The good news is that most HDMI cables are clearly marked. To transmit signals 4K you can choose to invest in a quick solution to the trays, as they can support higher-bandwidth 4K signals at up to five meters. Due to the high speed we are dealing with a data throughput of up to eighteen gigabytes per second, which is the standard specification for maximum capacity of data with HDMI 2.0.

Evolution of solutions with high resolution
The ancient founders of the HDMI interface-it is companies such as Hitachi , Philips , Sony , RCA and Toshiba , while the HDCP Protocol was originally developed by Intel.

The development of HDMI 1.0 began in April 2002, And its goal was to create a connector audio-visual, which was compatible with DVI. HDMI 1.0 was officially released in December 2002. Until may 2004, the HDMI 1.1 proposed multichannel audio of DVD-Audio . HDMI 1.2 added support for the HDMI interfaces on computers osobistychw August 2005. Until June 2006. HDMI 1.3 has provided a great opportunity throughput and higher bandwidth up to 10.2 gigabytes per second, which allows the interface supports 3D signals video. It was also released automatically control the synchronization of sound to get the perfect time playback of sound and image that was particularly useful in surround sound systems. HDMI 1.3 has also provided a new mini-connector for use with other devices, including digital cameras and camcorders.

In may of 2009. HDMI 1.4 added support for standard Ethernet which can connect one HDMI 1.4 device (connected to network) with other devices HDMI 1.4 adapted to the Internet using the HDMI cable with the same parameters. This interface also introduced the function of Audio Return Channel . Version HDMI 2.0 in September of 2013. Offered support for 4K video signal, and dynamic feature of automatic synchronization with audio .

The latest version of HDMI 2.0 (called HDMI 2.0 a ) added support for viewing the video of High Dynamic Range , which is characterized by good image quality and great level of detail in both dark and bright areas of the image. Was issued in April 2015.
