Advantage of the wisdom of the mini-HDMI cable

HDMI cable is used to transmit high-definition multimedia wire video signal. HDMI cable can transmit high-quality HD video and uncompressed multi-channel audio data, the maximum data transfer speed of 5Gbps. At the same time without the signal before electrical terminal block transmission / A or A / D conversion, can guarantee the highest quality audio and video signal transmission. Transfer directory 1HDMI data lines 2HDMI data line principle a mini HDMI cable data cable HDMI cable with a "plug and play" feature, automatically, "negotiation", automatically selects the most appropriate video / audio formats between the signal source and the display device. Volume compared with the wisdom of the mini-DVI mini usb cable is smaller, and can simultaneously transmit audio and video signals. DVI cable length can not be more than eight meters, otherwise it will affect the picture quality, but HDMI can transmit as far as 15 meters. As long as an micro HDMI cable, you can replace up to 13 analog transmission line, a home entertainment Vga extension cable system can effectively solve the tangled mess behind the wiring problem. Advantages: HDMI interface specifications in digital form can transmit uncompressed high-definition video and multi-channel audio data while maintaining the high quality of the case. Its superior performance beyond all previous products. HDMI specification connectors use a single connection, replacing the complex cable behind the product. Interface cable using the HDMI specification does not limit the length. For example: DVI cable length can not be more than eight meters, otherwise it will affect the picture quality, and meet the HDMI specifications do not have this problem. HDMI specification can be used with broadband digital content protection (HDCP), in order to prevent copyrighted audio and video content from unauthorized copying.

Twisted pair cable twisted around should meet the requirements

To reduce interference signals, twisted pair cable each wire pair is composed of two insulated copper wires twisted around each other together, and the same cable on different lines with different degrees of twist around (that is twisted coil how many there). Meanwhile, the standard vga to hdmi cable twisted pair cable wire pair is twisted counterclockwise conducted. However, some non-formal cable manufacturers, but there are many problems: ① In order to simplify the manufacturing process, the cable twisted around all pairs of the same density; ② line on the two insulated wires twisted around the density does not meet the technical requirements; ③ wire pair twisting direction does not meet the requirements. If there are more problems will cause near-end crosstalk twisted pair (UTP refers to the degree of signal interference between the two lines on), so that the transmission distance below standard. Twisted-pair twisted around degree in production has a more stringent standard, the actual purchase, in the case of a conditional number of professional mini displayport cable equipment available to measure, but the average user can only be observed with the naked eye. It should be noted that five UTP twisted around on the degree of midline than three dense, UTP than five secret. In addition to the two insulated copper wires twisted wire pairs according to requirements of the composition were twisted around the outside, between the standard UTP cable pairs must be twisted counterclockwise. Otherwise it will cause the cable resistance does not match, limiting the transmission distance. This is the average user rarely noticed. About the five twisted pair cables twisted degree and other relevant parameters, the interested reader may consult TIA / EIA568A (TIA / EIA 568 cabling standard is ANSI enacted in 1996, provides information on the basis of the standard network cabling Content facilities, including cables, connectors and other equipment. letter "A" is represented as IBM cabling standards, and AT & T said the letter "B".) specified in.

dvi use

DVI interface has + 5V voltage, hot plug detect (HPD) voltage requirements from this voltage acquisition, HPD active level should be greater than 2.4V, so the receiving device HPD series resistance should generally be less than 10kΩ. Applications receiving device can also use this voltage power supply for the system, but should not be greater than the load current 50mA, preferably less than 10mA, the level micro hdmi cable needed to ensure the HPD. To ensure the normal startup interface, EDID memory power at best + 5V generated by the sender. In order to ensure a viable hardware circuit design, software must also have support. Optimized software process is the key to ensure the normal operation of the DVI interface system. DVI interface voice patch panel for applied research on digital television, flat panel TV's, even more critical is the EDID (Extended Display Identification DATA, namely Extended Display Identification Data) programming, HDCP (High-bandwidth Digital Content Protection) function implementation. Those who are new to digital television applications, only after EDID and HDCP implemented on digital TV, DVI interface is the real digital TV interface. No broadcast there, how to use the correct method to output DVI video signal interfaces are accurate indicators of broadcast test, there is no one perfect way.

Advantages of micro hdmi cable

micro hdmi cable 1.3 version: 1, adds support for new lossless compressed digital audio formats Dolby TrueHD and DTS-HD Master Audio?'s. 2, the higher the refresh rate: 1920x1080 resolution in the same pattern, micro hdmi cable 1.3 offers 165Hz refresh rate than the dual channel DVI interface 120Hz refresh rate higher. micro hdmi cable 1.4 version: 1, Ethernet Channel: HDMI Specification 1.4 adds data path in the cable, and to achieve vga to hdmi cable two-way high-speed transmission. This function in the coupling device, the Ethernet cable can be used to speed 100Mb / s transmission and reception of data, and the equipment immediately becoming IP-based devices. HDMI Ethernet Channel will allow an integrated Internet-enabled HDMI devices without the use of additional Ethernet cable, you can share mini HDMI cable its Internet connection with other HDMI devices. This new feature also provides HDMI devices to share content between required interconnection architecture. 2, higher resolution: support 3840 × 2160 24Hz / 25Hz / 30Hz; 4096 × 2160 24Hz resolution. The new specification supports 4096 × 2160 resolution, making the HDMI interface to transmit content at the same resolution as many digital theaters used. The dual-channel DVI interface can support up to 2560x1600 resolution.
