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.
