I-HDMI encane: incazelo, injongo yesikhombikubona

I-HDMI encane - isixhumi senzelwe ukudlulisela ulwazi lwevidiyo eliphezulu nolwazi lomsindo ngeprotocol yokuvikela ikhophi eyakhelwe ngaphakathi. Inguqulo 1.3 yalesi sixhumano ibonakala ngokunyuka komkhawulokudonsa kwalesi sikhombimsebenzisi ngenxa yemvamisa yokuvumelanisa eyanda (340 MHz).

Incazelo yobuchwepheshe

Uhlobo lwe-HDMI oluthile lusho ukuthi lesi sixhumano sinesayizi esincane esilinganiselwe uma kuqhathaniswa nesilinganiso esisodwa. Lokhu kungenxa yezidingo zamanje zenqubo ye-miniaturization. Isixhumi esivamile sesikhombikubona esinjalo (uhlobo A) sinokulinganisa jikelele kwe-13.9x4.45mm, futhi inguqulo ye "mini" (uhlobo D) - 6.4x2.8. Ngakho umehluko ubukhulu kakhulu. Lolu buchwepheshe luyaqhubeka njalo, ngoba namhlanje kunezinguqulo ezine zomxhumanisi okhulunywe ngazo, ngamunye osebenzisa imininingwane efanayo yehadiwe kanye nekhebula. Umehluko ukwandisa umkhawulokudonsa kanye nohlobo lwolwazi oludluliselwa nge-connector.

Isicelo

I-HDMI mini Ngokuphathelene nomkhawulokudonsa nokusebenza akufani nhlobo evamile yesikhangisi se-A. Okungukuthi, iqukethe oxhumana nabo abangu-19 abafanayo. Ububanzi obuyinhloko bokusetshenziswa kwalesi sikhombimsebenzisi - lawa madivayisi aphathekayo, njengamafoni omakhalekhukhwini, amaphilisi, ama-laptops, abadlali bevidiyo namavidiyo wekhamera, kanye namanye amasu amaningi afanayo. Imfashini yemfashini yukusetshenziswa kwalesi sikhangiso kumakhadi wekhompiyutha womuntu siqu, ngoba isikhala esiteji sangemuva sinomkhawulo. Futhi njengoba ama-adaptator e-video avamile ejwayele ukusekela ama-DVI-I, ama-standard ajwayelekile e-universal standard, awekho indawo ye-interface ye-HDMI-hlobo A. Yingakho kunqunyelwe ukusebenzisa inguqulo encane yesixhumanisi.

Ikhebula le-HDMI elincane

Kufanele wazi ukuthi ubude bensimbi enjalo akumele kudlule amamitha angu-15. Izinhlobo zezixhumi (uthayipha u-A no-D), uma nje zinezinga eliphakeme, aziphazamisi ubude bomthamo obukhulu nganoma iyiphi indlela. Ngaphambi kokukhetha ikhebula elinjalo, kubalulekile ukucacisa ukuthi ubude buyadingeka. Ukuze wenze lokhu, udinga ukuqonda ukuthi izakhi ezixhunyiwe zizofakwa kuphi. Uma ungakwazi ukutshala imali kumamitha angu-15, kuzodingeka ukuthi usebenzise izintambo eziningana. Kodwa-ke, kulokhu kuzodingeka uthenge ama-amplifiers angeziwe . Ngaphezu kwalokho, lapho ukhetha intambo ede kunamamitha amabili, kudingeka uqiniseke ukuthi inezokuvikela okungeziwe, ngoba ngaphandle kwalolu khetho ikhebula ngeke likwazi ukunikeza ukudluliswa kwedatha eliphezulu .

Ukusekela amafomethi we-HDMI amancane

Lesi sikhombimsebenzisi sikwazi ukusekela zonke izinhlobo ezinkulu zamafomethi wevidiyo, kuhlanganise ne-NTSC, i-PAL, i-ATSC. Isixazululo sesithombe esithunyelwe sisefomethi eqhubekayo engu-1440p, noma i-2560x1440. Ngaphezu kwalokho, i-Blu-ray evamile ne-HD-DVD ingadlulisela okungaphezulu kuka-1080p. I-interface encane ye-HDMI isekela ukujula kombala okufika kuma-bits angu-48, okungaphezu kuka-280 trillion. Izinga lokuvuselela liyi-120 Hz. Ngaphezu kwalokho, ubuchwepheshe bevidiyo buzosekela amafomethi alalelwayo alandelayo:

• Icindezelekile (i-DTS, i-Dolby Digital nabanye);
• I-Multi-channel (DVD Audio, SACD);
• Umsindo ongaxhunyiwe (PCM): usekela iziteshi ezingu-8 ngesilinganiso sampula ka-192kHz kuma-24bits;
• Umsindo ocindezelekile nokulondolozwa kwekhwalithi (i-Dolby TrueHD, i-DTS-HD MasterAudio).
