The deep Analysis VGA and DVI

VGA (Video Graphics Array) in 1987 with the IBM PS / 2 machines with the launch of a video transmission standard, when high resolution, display rate, rich colors, etc., in the field of color display has been widely used.
VGA connector on the video card output is an analog signal interface, also called D-Sub connector. VGA connector is a D-type interface, the above 15-pin space, divided into three rows, each row of five. VGA interface is configured on the low-end mainstream computer interfaces.
Through the analog VGA interface connected to the computer monitor works, the computer display internal digitally generated image information in the video digital / analog converter into R, G, B primary color signals and horizontal and vertical sync signals, the signal transmitted by cable to the display device. VGA cable theoretically support 2048x1536, 60Hz mode, of course, need your display device and graphics support.
The analog display device, such as an analog CRT display, the signal is sent directly to the appropriate processing circuitry, the drive control tube to generate an image. As for LCD and other digital display devices, display devices must be configured to the corresponding A / D (analog / digital) converter, the analog signal into a digital signal. After D / A conversion and A/D2 times later, inevitably result in some loss of image detail. VGA interface used in CRT monitors is understandable, but it is used to connect the liquid crystal display device of the class, the conversion process will display an image loss decreased slightly. CRT monitor because the design and manufacture of reasons, can only receive analog signal input, which is why we only see on a CRT display VGA connector causes.
DVI (Digital Visual Interface), the digital video interface. It was in 1999 by Silicon Image, Intel (Intel), Compaq (Compaq), IBM, HP (Hewlett-Packard), NEC, Fujitsu (Fujitsu) and other companies jointly composed DDWG (Digital Display Working Group, Digital Display Working Group) launched interface standard.
Definition DVI interface position HDMI Splitter.
A DVI display system consists of a transmitter and a receiver. Transmitter is the source of the signal can be built into the graphics chip, the chip can also be added in the form of graphics on the PCB; while the receiver is the display of a circuit, it can accept a digital signal, which is decoded and passed to the digital display circuit, through both, the video signal as an image on the monitor.
And compared to traditional VGA signal, using a liquid crystal display DVI signals phase problem does not exist, does not cause pixel jitter. In addition, the use of DVI signals, the display will not cause geometric distortion, greatly improving the quality of the picture.

Knowledge of audiovisual electronic wire

 The original author is "Getting Started Audio visual facilities Basics - Video Interface chapter," describes the audio facilities outside the common video interfaces Here follow the editor to continue the "consciousness" about the most common audio interface bar.
It is currently the most common type of the line audio interface (external as indecent and integrated video interface), is often common for the two, transmit stereo sound. That kind wire connection end female late emerging era, being radio rca filling sound from the company invented, so it is called rca interface. rca audio side female pairs normally used to transmit basic stereo audio signals, commonly marked differences in color: red left channel (letter "r" indicates "left" or "Red"); left channel black or white. And it also carries multichannel no other types of colors.
Knowledge of audiovisual electronic wire entry audio-visual equipment basics - audio interface articles, xlr female balanced side
It is a kind of three-wire connection end female, three wires are reverse polarity, negative and shielding. xlr called "balanced side female" and "microphone plug", the normal terms of use are Boye or broadcast television category, but are some of the more top-class home audio installations are also commonly used to being pre-amplifier and the amp's between the signal transmission. xlr side woman advantage is that the equilibrium linear transfer signals that can be transmitted over long distances the audio signal is greatly reduced electrical female workers do the electromagnetic system, radio disturbance and the audio signal is generated outside the noise and hum.
Women's knowledge scale electric wire 1/4 inch (6.35mm) Labyrinth headphone plugs and jacks are designed to come from the early telephone wiring board, and that women are av class terminal equipment properly on a three-line layout (divided into left / left channel of each one and the ground), so the stereo signal output. Also commonly used Boye or broadcasting equipment on, and this was double layout (divided signal and ground) for transmitting mono signal; without also using the three line layout (divided into reverse polarity, negative and shielding) to equalize mono signal is transmitted.
The Labyrinth 1/8 inch (3.5mm) mini headphone end female little personal confidence will not unfamiliar to the bar. Its ongoing effectiveness and scale is the same as the female headphone end, used for portable equipment altar stereo signal HDMI to DVI.
According to spdif (sony-philipsdigitalinterfaceformat, Sony - Philips Digital Interface Format) of the scale, the appearance of women taking the same side analog audio rca wire can also be used to transmit digital audio signals. Female coaxial terminal can be used to transmit stereo (cd format) or multi-channel (Dolby Digital / dts) digital signal, plugs normally conducted with orange red and black label. Although any use rca plug wire can be used to transmit digital audio signals, but better to use specially designed for the digital audio cable to get the best possible transmission effect, that is, the impedance of the plug and socket must labeled 75ω.
bnc interface, features and doing it is to spend and coaxial end women are the same, just add a bayonet design, multi-Bo and broadcasting facilities are, the more stability.
woman toslink fiber end and coaxial rca side scale women are the same, are spdif digital audio format, the data transfer is not current through bumps, but by the light pulse, using a special optical fiber to make the amount of media. From toslink output port, you can see the red light, it is not a laser, it would not harmful to the human eye. Dirt and dust barriers to the transmission of light, so do not touch the connection when using the mouth, they also take Needless dust caps to the port, in addition, fiber optic cable is not excessively bent together can perhaps distorted, otherwise it will form of injury is always used instead of grams less.
Female end of the fiber optic necessary optical and two conversions, a bit lost signs appear, and cd signs outside jitee is constantly let Peng Ming heart engrave bone fever. But unlike copper susceptible to electromagnetic fiber nuisance is no better long-distance transmission can guarantee.

How much is the speed of HDMI?

About HDMI speed, there are a lot of explain, making it the designer in solving difficult problems ESD select an appropriate approach. People tend to think, according to the latest HDMI standard, that is HDMI 1.3, 340M pixels per second transfer, the data transfer rate of up to 10.2 Gbps. This is the exact system speed argument, but it is not the transition minimized differential signaling (TMDS) transmission speed. In order to select an adequate ESD protection solution, and also must take into TMDS speed.

In Recall that according to HDMI 1.3 specification, sending 340 M pixels per second, the system operates at up to 10.2Gbps. The key is "operates in the" six words. That is, the clock speed of the interface will change, depending on its top connected to the transmitter and receiver operate in the video capabilities. Therefore, the connection to the interface of the two devices higher resolution or color depth of the clock rate. HDMI only approaching the required number of pixels can be transmitted to the display device (monitor, LCD TV, etc.) on it. For example, if the high-definition digital video disc (DVD) players, and liquid crystal display (LCD) monitor during playback 1080P high definition video format, color depth of 48 bits, compared to the 480i standard definition DVD playback programs, more information is to be processed.

Various resolutions and the corresponding number of pixels per line and lines per frame. Listed in Table 1 for each color depth, and it has a number of bits corresponding to each pixel's color transfer. From the HDMI transmitter to the receiver's HDMI Converter amount of data related to these variables, including the number of frames per second refresh the display. Table 2 describes this relationship:

HDMI data transfer rate = X * Y * F * B

Where: X = number of pixels per line; Y = number of lines per frame; F = the number of frames per second; B = number of bits per pixel.

HDMI line purchase Precautions

HDMI technology is now widely used in the field of video, such as the current high-definition televisions, computer graphics, digital devices so widely with HDMI interface. HDMI biggest feature is that it can simultaneously transmit video and audio signals, and has interfaces compact features. Currently HDMI version HDMI1.4 has launched the latest version, but the vast majority of video equipment is used HDMI1.3 version, so when buying HDMI cable also needs some attention. Here the simple introduction from Shenzhen HDMIcabler Technology Co., Ltd. 

HDMI has been introduced time is not long, but its growth rate is very fast. HDMI Since its launch, has evolved from version 1.0, version 1.1, version 1.2, 1.2a version to version 1.3 development. Compared with the previous version, HDMI1.3 version has greater bandwidth doubled from the original 4.96Gbps to 10.2Gbps, able to transmit higher flow HD programming; HDMI1.3 version number of colors supported is also higher, HDMI1. 1 and version 1.2 only supports up to 24bit color depth, Version 1.3 HDMI interface is significantly expanded to 30-bit ,36-bit and 48-bit (RGB or YCbCr); HDMI1.3 version also adds support for multi-track high-traffic uncompressed or lossless compression audio source (such as DolbyTrueHD and DTS-HDMasterAudio) support. That is, if the interface and wire are HDMI1.3 version, then it can transmit higher bit rate, a higher number of colors, with better-quality high-definition television programs.

Introduction of any technology, it has a certain period of development, the HDMI come out, because of technical limitations, many have had to use HDMI cable handmade, which also led to its price high. Although the repressive machine HDMI cable has dominated the market, but the manufacturing process or the high and low, especially in joints of the process, the core technology vendors generally simply no way to grasp. Some HDMI cable exterior looks fine, but actually when we use it ,it shows not good. Therefore, we buy HDMI cable, pay special attention to the manufacturing process.

Of course, a good HDMI cable transmission signals which are very convenient, it should use copper as the inner core, so that it is more conducive to guarantee the quality of the transmitted signal. Those who cut corners, poor quality of HDMI, the cost will be much lower iron or other alloy materials. Because we buy a HDMI cable and can not see what is inside it is the use of the material, so they are often judged by feel it. In general, the use of copper for HDMI Extender relatively soft, it is also easier to bend, using the iron core is not, bend it seemed hard. If the conditions, you can also take the magnet under test, can determine whether to use a HDMI cable cores up. Good HDMI cable is not soft nor too hard.

Demand for HDMI signal acquisition, we have also introduced a HD HDMI capture card, T220E universal definition HDMI capture card, Dual Link HD HDMI capture card, it can capture high-definition HDMI audio and video signals, and is compatible with most currently available streaming media applications. If you have additional questions in the application or suggestions you can consult our online site technical customer service, or call for inquiries.

Steps to Follow to Connect a Blu-ray DVD Player to a TV with No HDMI Connection

HDMI has provided us with many wonderful products; Blu-ray is one of them. But when you think of having a Blu-ray DVD player, you get disappointed if you don’t have an HDMI television set. The good news is that you can connect your Blu-ray DVD player with your TV even if your television does not have an HDMI port. You can enjoy high definition picture and sound through your Television with the help of component cables. The only disadvantage could be that the number of cables required is more.

You will require the below things:

· One Composite audio cable

· One Component video cable

Step-by-step instruction to connect Blu-ray DVD player to a TV

· By using the Component cable, connect one end of the component video cable to the “component out port” of the Blu-ray DVD player. But make sure to match the cable colours properly with the port colours. A small mismatch with the colour combination may fail to provide the required results.

· Now connect the other end of the component video cable to the Television’s component in port. The ports could be located at the rear end, on the sides or in the front. Do make sure to match the cable colours and port colours properly HDMI Cable.

· The video input and output are connected successfully. However, the audio signal connection is missing. This will be done with the help of composite audio cables.

· The composite audio cable will have one red and one white cable. Connect it with the Audio out port of the Blu-ray DVD player. Again make sure to match the colours. Now similarly, take the other end of the composite audio cable and connect it to the Audio In port of the television. This final step will ensure that the connection setup is successfully done.

Points to Know Before You Upgrade to HDMI Gaming

In this era of technology, new products are being launched every day in the market. And as these new products reach the market, consumers get excited to use them. But problem arises when they start having doubts and question about the new technology. Some might conclude it as bug, while some might consider it as an enhancement. 

Similarly when it comes to gaming, the world of HDMI cannot be left behind. However, before considering for upgrading to HDMI gaming, consumers need to know the new technology. Most of the people are accustomed with VGA or DVI gaming, only a few of them is aware about HDMI gaming. So here are some of the points that consumers need to know:

Things to know before upgrading to HDMI Gaming

· Audio Capability: HDMI gaming has the capability to control the audio as well as the video. And as this is something new, most of the people are not aware that they can enjoy the audio with HDMI gaming through PC. The video card with HDMI includes PC audio and that is also of high definition sound. Also a provision has been made whereby you can pull out the audio cord and still enjoy the high definition graphics.

· HDMI Bandwidth:  Due to high bandwidth, you can transfer large amount of data of HDMI as compared to VGA or DVI. This helps to cope up with the bandwidth of new graphics card.

· Transition to HDMI gaming from VGA: Most of the time, it has been seen that consumers are happy in their comfort zone and thus it becomes difficult for them to accept new technology. But with DVI Cable, the gamers will be more than satisfied by the graphics quality in video along with high definition audio. This is because VGA is analogue and HDMI is digital.

How to Select a Good HDMI Cable

Everybody wants to buy a good HDMI cable. But not everyone is aware about the facts that should be considered before getting the one. Due to this, some not so well-informed customers end up buying a cable that does not serve their purpose fully. As a result, they have to replace the whole product. So why ‘buy cheap and pay twice’?

Any of the HDMI cable unless damaged performs really well. So it is not very difficult to buy the right HDMI cable. To make your buying choice easy, I am sharing a few critical points here.

Points to Consider

First, you should know how it really works. HDMI cable sends high quality image and sound streams over a small connector to the connected devices.

Second, HDMI cables are available in 4 various types: 

1. Standard – rated for 720p to 1080i signals.

2. Standard with Ethernet – rated same as standard ones but comes with a wired Ethernet local network connection.

3. High Speed–designed to handle more data at a time and intended for 1080i signals.

4. High Speed with Ethernet–furnished with High Speed capabilities but come with Ethernet support.

One more type that has not been mentioned above is the one used for automobiles. Cable manufacturers are required to clearly specify the type on the cable itself. Besides, sometimes you may also find that cable versions are being mentioned. But don’t worry about this factor as the HDMI licensing organisation doesn’t currently allow manufacturers to put versions on the HDMI Adapter.

Lastly, other factors which again should not be a big issue are the price and the brand names. A $20 worth cable would provide you same picture quality and sound as the one that is priced for $60. After all, the quality of the image is what matters the most.
