HDMI for HDTV

HDMI (High-Definition Multimedia Interface) is now the standard digital audio-video cables for HDTV. HDMI, simplifying installation, integrating all channels, improving performance. HDTV signals are a great challenge for the sale. Compressed if your service provider distributes the signal from a satellite to write home about, the signal is (see MPEG) to reduce the bandwidth. Once the signal is received by the receiver, the signaluncompressed. HDMI can handle the signal at full bandwidth, as opposed to the old standards such as Firewire.

HDMI is the industry-supported specification. It is not a specific owner who tries to force a manufacturer on the market. The industry needed a high quality digital connection, and consumer electronics manufacturers decided, a standard that could benefit both industry and consumers

A DVI connection offers equivalent performance to HDMI. In fact, HDMIbuilt according to the standard DVI. However, DVI is problematic because an interface has not been met rigorous standards. HDMI should ensure that equipment will remain compatible. The HDMI connector is compatible with existing DVI video input that is used in most PC graphics cards. The HDMI integrates all video signals such as component video, where each of the (red, green, blue) RGB signals must meet its own cable. Older interconnect technologies such as S-video orComponent video, audio signals must be treated separately, and the performances are slightly worse than HDMI.

Interoperability can be a problem with standards such as HDMI. Most of these problems come from improper use of technology implementations. If there are problems, the group of HDMI standard is needed to solve the problem. Some products have been recalled. Exceptions are some set-top boxes used by some local cable TV company. These are some of the fieldsCompatibility issues that the cable company is not willing to solve.

HDMI allows two-way communication between components, so that for example, your HDTV can tell the source, if the picture is 16:9 or 4:3. HDMI integrated remote control so that all HDMI-compatible modules can be controlled with a remote control. Press the play button to start your Blu-Ray DVD, and not only DVDs, but the HDTV and audio components will turn on automatically.The HDMI standard is used "Consumer Electronics Control" (CEC) called. The companies have their own trade names for CEC. Examples are "Anynet" from Samsung, 'BRAVIA Theatre Sync "Sony," Link "Pioneer" Kuro EasyLink "by Philips, and" NetCommander for HDMI "by Mitsubishi. All HDMI devices to be compatible with each other.

High-bandwidth Digital Content Protection (HDCP) is a software protection system, which is included with the HDMI ports to prevent unauthorized copying of protectionMaterial. This can sometimes cause compatibility problems, but HDCP is a necessary evil. As more content is delivered digitally, content producers are always concerned with piracy, because the content can be copied perfectly. Without copyright protection, the producers of content such as movie studios are not willing to sell their product. Most programming is only at full resolution HDCP protected outputs.

Most HDTV sets currently available are two or moreHDMI inputs so that HDTV different from the service provider (eg, satellite), Blu-ray DVD player, game console and / or computers can be connected. If you are choosing your HDTV set now, note the number of HDMI inputs if and how many might be needed in the future. If the device does not have enough inputs, you may need to add an HDMI switcher system. Figure spending about $ 100.

Integrated with HDMI audio signals. HDMI can handle eightChannels 24-bit audio at 192 kHz, enough for a surround sound system 7.1. This is necessary for the surround sound like Dolby TrueHD and audiophiles programming programming as DTS-HD Master Audio. A Dolby TrueHD bitstream can be up to 14 discrete channels. DTS-HD Master Audio delivers audio at very high rate of 24.5 mega-bits per second (Mbps) on Blu-ray DVD. In addition, DTS-HD Master Audio 7.1 channel audio frequency/24 96k sampling bit depth.

There are different versions of HDMI cables. It also includes the standard "A" connection, there is a "mini-HDMI" (type "C"), exactly as it sounds: a smaller version for use with small peripheral devices, such as a camcorder. A special cable with a small cap at one end and a conventional "A" on the HDMI portother end is necessary. Another variation is "HDMI 1.3", presumably an improved version of HDMI is capable of "Deep Purple" are. According to the HDMI connection, 98 percent are currently selling the HDMI cable is compatible with HDMI 1.3.

HDMI cable length is an important consideration. Everything has the potential for more than 30 meters to a substantial deterioration of the signal, but the cable length of 75 meters or less in most cases OK. There are significant differences betweenexpensive cables ($ 50 or more) and cables to find the cheap discount, or better yet an online retailer like Amazon.com. All cables marked the HDMI logo needs to be tested on an HDMI Authorized Testing Center. It should cost a 6-foot cable is less than $ 10. Save your money for items where the money is actually something.

HDMI has become the de facto standard for HDTV connections. Although some of the HDMI features are probably not fully implementedon the current device when an upgrade will most likely support the needs of HDMI interconnection, at least for the near future.
