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 major challenge for sales. If you develop the signal from your service provider, such as from a satellite for your home, the signal is compressed (see MPEG) to reduce the bandwidth. Once the signal is received by the receiver, the signaluncompressed. HDMI, the control signal at full bandwidth, compared to older standards such as Firewire.

HDMI is an industry-specific support. There is no property right to the specification that a manufacturer tries to push the market. The industry needed a high quality digital connection, and consumer electronics manufacturers decided, would benefit from a provision that both the industry and consumers

A DVI connection offers equivalent performance to HDMI. In fact, HDMIis built on standard DVI. However, DVI was problematic, because a strict interface standard was not met. HDMI should ensure compatibility of the device will remain. The HDMI port is compatible with the current video input DVI graphics card that is used on multiple PCs. The HDMI integrates all video signals, as opposed to component video with each of the RGB (red, green, black) signals its own cable. Old interconnect technologies such as S-Video orNeed component video, audio signals are processed separately, and its performance is slightly worse than HDMI.

Interoperability can be a problem with standards such as HDMI. Most of these problems are caused by incorrect application of technology. If there were problems, the group has demanded that the HDMI problem. Some products have been recalled. Exceptions are some set-top boxes used by some local cable TV company. Some of the fields arecompatibility issues that the cable companies are not prepared to solve.

HDMI enables a 2-way communication between the components, so that for example you can tell the source of HDTV signal, if the picture is 16:9 or 4:3. HDMI integrated remote control so that all modules compatible with HDMI can be controlled with one remote. Press the Play button to start the Blu-Ray DVD, and not just the DVD, but the HDTV and audio components are switched on automatically.The standard used by HDMI Consumer Electronics Control (CEC). The companies have their own brand to the CEC. Examples are "Anynet" from Samsung, 'BRAVIA Theatre Sync for Sony, "KURO LINK" Pioneer, "EasyLink" by Philips, and "NetCommander for HDMI" from Mitsubishi. All HDMI devices are compatible with each other.

High-bandwidth Digital Content Protection (HDCP) system is the software that is included with the HDMI ports to prevent unauthorized copying of protectionMaterial. This can sometimes be compatibility problems, but HDCP is a necessary evil. As more content is delivered in digital content producers are increasingly concerned with piracy, because the content can be perfectly reproduced. Without the protection of copyright, would the producers of content such as movie studios will not be willing to sell their product. Most programming languages ​​only be extradited to output full resolution HDCP protected.

Most HDTV sets currently available are two or moreHDMI inputs, so that different signals are connected to the HDTV service providers (eg, satellite system), Blu-ray DVD player, game console and / or computer can. If you are choosing your HDTV now, note the number of HDMI inputs, and consider how many inputs may be necessary in the future. If the device does not have enough inputs, you may need an HDMI switcher Add to your system. Figure to spend about $ 100.

HDMI with integrated audio signals. HDMI can handle eight24-bit audio channels at 192 kHz, enough for a 7.1 surround-sound. This is necessary for the surround sound programming, including programming such as Dolby TrueHD and DTS-HD Master Audio audiophile. A Dolby TrueHD bitstream can be up to 14 discrete channels of audio. DTS-HD Master Audio offers the very high rate of 24.5 megabits per second (Mbps) on Blu-ray DVD-Audio. Additionally, DTS-HD Master Audio 7.1 channel audio to 96k sampling frequency/24 bit depth.

There are different versions of HDMI cables. In addition, the type of series "A" connector, there is a "Mini-HDMI (Type" C "), which is exactly what it seems: a smaller version for use with small devices such as a camcorder. A cable special with a small connector on one end and a conventional type A HDMI connector on thethe other end is required. Another version is "HDMI 1.3", which is supposedly an improved version of HDMI-capable "Deep Purple". After the HDMI Association, 98 percent of sales currently HDMI-compatible with HDMI 1.3.

HDMI cable is an important consideration. About 30 meters has the potential to lead to a substantial deterioration of the signal, but the lengths of 75 meters or less in most cases OK. There are significant differences betweenexpensive cables ($ 50 or more) and low-cost cable found your discount, or better yet, from an online retailer like Amazon.com. Each cable has marked the HDMI logo have been tested on an HDMI Authorized Testing Center must. should cost a 6-foot cable is less than $ 10. Save your money for the low where the money actually accomplishes something.

HDMI has been connected as de facto standard for HDTV with each other. Although some of the features of HDMI are probably not fully implementedon your current system, once you upgrade, probably will support HDMI interconnection requirements, potential, at least for the future.
