Tips on Connecting the HDMI Computer Connection to Your Television

Connecting the computer to the TV screen will be the useful way in displaying the presentations or even videos on the larger screen or easy to use the TV screen as the monitor. When you are using the TV as the monitor, it will be important for you to have as high the screen resolution as possible therefore the small text of the computer desktop and also windows is legible.

If the video card of the computer has the HDMI output, HDMI is the great way to connect it to the HDTV to maximize the picture quality. Here is more information for you.

For the first step, you need to place your computer close enough to your TV therefore your HDMI cable can reach from one to the other.

For the second step, plug one end of the HDMI cable into the HDMI port on the video card of the computer. For the next step, you should plug the other end of the HDMI cable into the open HDMI input port on your TV.

Most of HDTV's have the HDMI input on the side of your TV for simple on demand access. If the TV will not have a port on the front or even side, you will need to plug it into the port on the back. After that, turn on the TV and also the computer.

For the last step, you can use the TV remote control in order to change the video mode to an appropriate HDMI connection. It just like when you will switch from watching TV to using the DVD player or even game console, you will need to switch the input mode of your TV to use the HDMI connection that the computer is plugged in to.

HDMI: Guide to HDTV Connection of the Future

Background:

As the HDTV market continues to heat up, consumers are required, formed on the cutting edge of technology. One of the terms that you, the consumer is safe to run during the selection of a set HDTV: HDMI. For the most part it is an unknown concept, and explains the details of HDMI in this article, so that you, the consumer is armed with the right knowledge to make intelligent purchasing decisions.

What is HDMI: HDMI stands for High Definition Multi-MediaInterface. The HDMI specification (now 1.2) was created by some of the largest manufacturers of consumer electronics in the world: Hitachi, Matsushita, Philips, Silicon Image, Sony, Thomson and Toshiba. HDMI is the new standard for HDTV digital interconnect. The large difference between HDMI and the earlier HDTV interconnects standards (component video and DVI) are:

HDMI is all digital unlike analog component video cable

HDMI supports multi-channel audio in addition todigital video. (DVI only supports digital video)

- HDMI is compact and has eliminated both audio and video signals, and clutter.

Integrated HDMI content protection called HDCP (High Definition Content Protection)

What does a HDMI connector type: HDMI is similar to a USB cable. The compact size and high integration (carries both audio and video) makes the HDTV installation experience truly "plug and play".

Why should IHDMI:

HDMI is a digital, so picture quality is "perfect" from source to screen

HDMI is a digital audio and video connections. This minimizes system wiring

HDMI is rapidly becoming the de facto standard for HDTV connections.

How does HDMI transport the digital video: The video is part of the HDMI performed by 3 separate differential pairs. Each pair transports 1 of 3 uncompressed native digital R, G, B signals from the source (DVD player, set-top box)the sink (HDTV display). A single protocol TMDS (transmission minimized differential signaling), is used for the transport of digital data. Each pixel is represented by 24 bits (8 bits each for each primary color). The TMDS protocol then "calculates" and food for 2 bit more for the video stream to a digital data stream to create the minimum transitions (lower EMI, lower interference) and also minimize long strings of '1 ' and '0', which may cause detection errors.

Afourth differential pair, called the TMDS clock provides the pixel clock for timing the data stream. The maximum TMDS single link pixel clock rate is 165 MHz.

What is the data rate of a single link HDMI connection: The maximum pixel clock is 165MHz and each of the 3 TMDS video streams carries 10 bits. Therefore, the aggregated data is 3 x 10 x 165MHz = 4.96Gbps.

How many pins are included in the HDMI connector: There are 19 individual pins in HDMI port. There are 3Pairs of TMDS signals to carry all digital audio and video signals.

Since the digital audio signal is delivered: the multi-channel audio is the time in the TMDS data streams combined. The audio is much lower data rate (192 kbps) and the extra time is used to demux the audio signals.

What is HDCP: HDCP stands for High-Bandwidth Digital Content Protection. HDCP is an encryption method developed by Intel in order to control unauthorized copying of digital media. L 'Encryption is found success in the HDMI transmitter in "source" (DVD player, set-top box) and decryption is done by the receiver HDMI (HDTV) is performed. The secret keys for encryption are exchanged between the source and display over an I2C bus (pins 15 and 16).

It is compatible with HDMI-DVI: DVI is the predecessor to HDMI. HDMI and DVI are identical as regards the video goes. Therefore, there is video compatibility. However, DVI does not support digital audio.For example, if you have an older DVI connection on the source and an HDMI port on the display, a DVI-HDMI cable all you need to watch this video. A separate audio cable (TOSLINK or SPDIF) are needed, which will bring digital audio.

What formats are supported HDMI: HDMI is a high-speed digital connection and resolutions of 480i, 480p, 720i, 720p, 1080i and in the future, support 1080p.

Conclusion:

HDTV technology is changing rapidly. HD connectionssuch as HDMI will become the de facto standard in HDTV connections. We have outlined the main features of HDMI, so that consumers are well informed and prepared to make smart choices.
