Phetiso ea Optical
Ho tloha 2000, ka nts'etsopele ea thekenoloji ea puisano, puisano ea optical fiber e hlahile theknoloji ea phetisetso ea optical module, 'me ka mor'a 2002, lihlahisoa tsa li-digital HDMI le lihlahisoa tsa lipontšo tsa video li boetse li hlahile tšimong ea lisebelisoa tsa elektronike tsa bareki.Ka April 2002, Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, Toshiba lik'hamphani tse supileng li ile tsa theha mokhatlo o hlophisitsoeng oa li-interface oa HDMI o nang le tlhaloso e phahameng ea li-multimedia, phetisetso ea HDMI e arotsoe ka mokhoa o phahameng oa ho fetisa le ho fetisa likarolo tse peli. : 1-12 maoto a li-pair tsa 12 4 tsa lik'hebole li fetisa matšoao a lebelo le phahameng, li sebelisa theknoloji ea TMDS ea phapang (TMDS (Time Minimized) e qapiloeng ke Silicon Image Differential Signal) e fokotsa theknoloji ea phetisetso ea phapang ea phetisetso, TMDS ke mochini oa matšoao a fapaneng, o sebelisa mokhoa o fapaneng oa phetisetso, e leng molao-motheo oa motheo oa theknoloji ea HDMI, ho optical fiber transmission HDMI: li-pair tsa 4 tsa lithapo tsa 12 TMDS li fetisoa ke 4 VCSEL + 4 multimode optical fibers, e ka rarollang bothata ba ho fetisa ka lebelo le phahameng habonolo.
Ka mocha oa phetisetso ea lebelo le tlase la HDMI, likhoele tsa 13-19 ho HDMI li na le likhoele tsa elektronike tsa 7: matla a 5V, HPD hot-swap e sebetsa CEC, marang-rang, SDA, SCA, DDC.Qeto ea bohlokoa ka ho fetisisa ea pontšo e bala mocha oa DDC: ke taelo ea sebopeho sa I2C mohloling oa HDMI ho bala E-EDID qetellong ea ho amohela.I2C, e khuts'oane bakeng sa Integrated Circuit Bus, ke libese tsa puisano tsa serial tse sebelisang boqapi ba makhoba a mangata.Mothehi oa I2C hape ke e mong oa bathehi ba mokhatlo oa HDMI: Philips Semiconductors.
