http://www.godlines.com.cn/ Dongguan Jia Yue Electronics Co., Ltd. specializes in producing high-definition multimedia HDMI cable link, the link is not only to meet the 1080P resolution, but also support DVD Audio and other digital audio formats, support for eight channel 96kHz or stereo 192kHz digital audio transmission, you can send uncompressed audio and video signals. HDMI can be used in set-top boxes, DVD players, personal computers, video games, integrated amplifier, digital audio and TV. HDMI can transmit audio and video signals simultaneously. HDMI support EDID, DDC2B, and therefore has a HDMI device has a "plug and play" feature will automatically "consultations" between the source and display devices, automatically select the most appropriate video / audio formats. Volume Compared with DVI HDMI interface, smaller cable length HDMI / DVI optimum distance not more than eight meters. As long as a HDMI cable can replace up to 13 analog transmission line, can effectively solve the family * messy tangle of wires behind the system problem. HDMI to ensure maximum quality, while in a customer-centric philosophy, the company in the production of HDMI, did a special test, for example: a, output compatibility testing, mainly refers to: HDMI interface can transmit audio supported "by any S / PDIF output of compressed digital audio" and "2/6/8 channel, 32-192KHZ sampling rate of uncompressed digital audio" that can output "I2S (a digital transmission interface, the performance difference better than S / PDIF, suitable for short distance communication) and SPDIF audio "; it always have access to audio CD quality; HDMI interface can transmit video support" HD 1080I "," high-definition 720P "," ordinary interlaced "and" ordinary progressive ", while supporting NTSC and PAL TV system; can automatically output according to the receiving end can accept video status" YUV "or" RGB "encoded video format; second, port plug 1 reliability testing. Interface Hot Plug Reliability: Under state dishwasher and sink are working, plug the HDMI interface, if the device is working properly at both ends, HDMI output audio and video functions are normal; 2. ESD test 3. Interface plug life test: multiple plug HDMI, HDMI interfaces life test; criteria: The hot-plug receiving end of normal output HDMI audio and video signal source end system must still work; the interface plug life requires a minimum more than 5000 times; three, reliability test output, specialized testing HDMI can transmit up to 30 meters, to ensure sound image properly; large-capacity DVD (subtitles, multiple channel) four discs, playback screen fluency; 4. Boot, standby, HDMI output is normal. Fourth, the testing standards, according to the vendor's HDMI port and cable testing standards; five non-normal operating conditions HDMI port output test, main point is that, in the case of a specific temperature, voltage and time parameters Junior dishwasher; under these conditions, you need audio and video features HDMI interface work; 6, the output port function test 1. HDMI port supports 1080P, 720P HD format video output; 2. HDMI port supports a variety of compressed and uncompressed digital audio output; 3. Auto Detect accepted Aspect Ratio equipment; criteria: in the same sources, HDMI HD output image quality should be "clearer, flicker-free, expressive details on stronger, more realistic colors" than CVBS and ordinary color ( You can use high-resolution JPEG image or DVD demo disc to demonstrate the effect); if accepted TV device can decode the digital audio signal from the HDMI input on the receiving end should have sound output; HDMI output can be used to automatically adjust the output aspect ratio to adapt to the receiving device. Kerry is not the cost it takes most concern, the customer was safe, HDMI cable service life, as well as HDMI meets the current needs of people, the more people become a problem Kerry total attention, with the best quality, the best quality service, the most inexpensive prices back to US users, that is, the more Kerry continued in the power struggle.
