Izintambo ze-I-I-I-HDMI zivame ukusetshenziswa futhi zibalulekile. Yikuphi okungcono?

 

 

Abangani abavame ukudlala imishini yevidiyo echaza ephezulu bayazi ukuthi i-I-I-I-HDMI isikhombimsebenzisi esivame kakhulu sokudluliswa kwesiginali yevidiyo, kepha i-I-I-I-HDMI inezinhlobo eziningana ze-I-I-I-HDMI1.4, I-I-I-HDMI2.0, I-I-I-HDMI2.0a, njll, njengomuntu ongayiqondi imininingwane yezobuchwepheshe Abasebenzisi, kunzima ukukhetha.

 

I-I-I-HDMI is an important way to link high-definition multimedia and TV. This is a digital video/audio interface technology that can transmit video signals and audio signals at the same time without digital-to-analog conversion, and it is very convenient to transmit video and audio Signal; video decoding output device, through I-I-I-HDMI can transmit video and audio to the delivery device with extremely high efficiency, it can work several commonly used multimedia devices such as smart TVs, set-top boxes, projectors, etc.

 

In a few words, I would like to introduce the history of this line; the first technology that appeared in the field of digital transmission was DVI instead of DHMI. With the development of digital high-definition audio-visual technology, there are more and more problems with the DVI interface, so it involves multiple Manufacturers in the field urgently need better high-definition video interface technology, which prompted the birth of the standard I-I-I-HDMI; it can be seen that this high-definition video link will also play an important role in the connection of multimedia devices in the future.

 

 

 

I-I-I-HDMI interface type

 

 

I-I-I-HDMI interfaces are divided into four types: A, B, C, and D.

 

Among them, Type A (Type A) is the most common. Generally flat-panel TVs or video devices provide interfaces of this size. Type A has 19 pins, a width of 13.9 mm, and a thickness of 4.45 mm. Devices that can be seen now 99% are I-I-I-HDMI interfaces of this size.

 

Uhlobo B (Uhlobo B) alutholakali kakhulu. Inezinaliti ezingama-29 nobubanzi obungu-21 mm. Umkhawulokudonsa wokudlulisa ucishe uphindwe kabili kunowohlobo A. Unamandla amakhulu kakhulu ekusetshenzisweni kwasekhaya, futhi usetshenziswa kuphela ngezikhathi ezithile zobungcweti.

 

Uhlobo C (Uhlobo C) lwenzelwe amadivayisi amancane. Usayizi wayo ungu-10.42×2.4 mm, ecishe icishe ibe ngu-1/3 incane kunohlobo lwe-A, futhi ububanzi bayo bokusebenza buncane kakhulu.

 

 

 

Uhlobo D (Uhlobo D) uhlobo lwakamuva lwesixhumi esibonakalayo. Usayizi wabuye wehliswa. Yamukela idizayini ephini ephindwe kabili. Usayizi uyefana nesixhumi esibonakalayo se-miniUSB, esifaneleke kakhulu kumadivayisi aphathekayo nangaphakathi kwezimoto.

 

 

 

Although the I-I-I-HDMI interfaces are different, the functions are the same. Usually, the quality of the I-I-I-HDMI interface is not less than 5000 times of plugging and unplugging. It can be used for 10 years when plugging and unplugging every day. It should be said that it is very durable. It is also worth mentioning that I-I-I-HDMI can be backward compatible with the DVI interface. Some older DVI devices can be connected through commercially available I-I-I-HDMI-DVI adapters, because DVI also uses the TMDS method. After the device is connected, DVI devices will be found. There is no CEC (consumer electronics control) function, nor can it accept audio signals, but it basically does not affect the transmission of video signals (gray adjustment may be required), so some monitors with only DVI interface can also be connected to I-I-I-HDMI devices.

 

 

 

I-I-I-HDMI function

 

 

Ngaphezu kwezinhlobo ezahlukahlukene, i-I-I-I-HDMIisikhombimsebenzisi sihambisana nemisebenzi ehlukile.

 

 

Eyokuqala: i-HDCP 2.2, lobu buchwepheshe bungavikela ama-movie enani eliphezulu, imibukiso ye-TV nokuqukethwe komsindo ekwebeni nasekukopisheni okungekho emthethweni.

 

The second: I-I-I-HDMI-ARC (Audio Return Channel, sound return) function, used for the output of TV digital audio, you can connect an amplifier that also supports the ARC function, and transmit the sound of the TV to the amplifier.

 

Eyesithathu: i-bit isho ukujula kombala. Isikrini sokubhalela okujwayelekile yi-6bit, i-high-end 8bit, kanye ne-10bit ekhethekile yobuchwepheshe, engaqondwa njengokujula kombala okungu-2 kuye kumandla we-10, futhi i-10bit ibhekisa ngqo kubuchwepheshe bokubhala ngevidiyo obunganikeza ikhwalithi ephezulu kakhulu yevidiyo , Iyakwazi ukukhombisa ubumnandi obedlulele ekushintsheni kancane kancane nasekushintsheni kwemibala, kepha izidingo zokucushwa ukuze zikwazi ukudlala i-10bit zisephezulu kakhulu.

 

Okwesine: Ubuchwepheshe be-MHL busebenzisa izintambo ezinhlanu kuphela ukudlulisa ividiyo engacindezelwe efinyelela ku-4K ene-digital-channel digital audio, ngenkathi futhi ishaja amadivayisi eselula.

 

 

 
Advantages of I-I-I-HDMI

 

 

1. Ikhwalithi enhle: I-interface ye-digital ayinakho ukulahleka kokuguqulwa kwe-analog-to-digital futhi inganikeza ikhwalithi yevidiyo ehamba phambili. Kubonakala kakhulu ezinqumweni eziphakeme, njenge-1080p noma i-4K.

 

2. Isebenziseka kalula: Umugqa owodwa uhlanganisa amasiginali wevidiyo namasiginali womsindo weziteshi eziningi, okusebenza kakhulu kunesimo lapho imigqa eminingi yayixhunywe khona esikhathini esedlule.

 

3.Ukuhlunga:I-I-I-HDMI supports two-way communication between video sources and playback devices, realizing new functions, such as automatic configuration and one-key playback. By using I-I-I-HDMI, the device automatically transmits the most efficient format for the connected display device (for example, the TV supports up to 4k30P, I-I-I-HDMI will return the information, and the box will automatically set the resolution to 4k30P), so the user does not have to try to set it by himself Resolution.
