HDMI-socket: kev twb kev txuas

Xav txog pinout nrov tshaj plaws yog nyob deb, lub HDMI ntsawb (qhov no yog qhov A-hom thiab C-hom). Raws li twb tau hais saum toj no, ob qho tib si ntawm cov interfaces muaj 19 pins, tsuas txawv yog qhov chaw. Lub A-hom terminals cov txheej txheem ntawm nyob rau hauv ob kab, thiab nyob rau hauv lub P-hom - ib tug. Pin hauj lwm yog qhia nyob rau hauv cov kev yees duab. Numbering cov lus xaus P-hom yog nyob rau hauv kev txiav txim, thiab nyob rau hauv lub A-hom qaum kab yog khib, sab - txawm.
