Tofauti kati ya HDMI na DisplayPort

2021-04-06

TheHDMICuwezonaDisplayPort Cuwezoendesha kwenye muundo sawa wa kimsingi na utofautishaji wa jozi iliyosokotwa ya coaxial, na zote hutumia ishara za kasi za kasi na za chini kutofautisha data, lakini huo ndio kufanana tu kati ya hizo mbili.

 

Ingawa viwango hivi vinafanana sana kwa sura, kuna tofauti kubwa katika muundo. Tofauti hizi huamua utendaji wa kiunga na gharama yake, utangamano, uthabiti, na urahisi wa utekelezaji.

 

TheHDMIcuwezos standard now defines four connectors, A to D. Except for Type B, the rest are 19 pins. Type C and D are aimed at portuwezo applications and small-volume devices. Thecuwezos used by the two standards are slightly different.

 

HDMIcuwezos 1.0 to 1.3 use 4 shielded coaxial differential pairs, 4 single-ended control signals, power (+5V) and ground wires. HDMIcuwezos1.4 inaongeza kituo cha kurudi kwa sauti na kituo cha Ethernet, kwa hivyo muundo wa ishara ni tofauti. HDMI1.4 hutumia jozi 4 za coaxial, jozi 1 tofauti isiyosimamiwa, ishara 3 za kumaliza moja, usambazaji wa umeme (+ 5V) na ardhi.

This means that HDMIdata cuwezo 1.4 and HDMIdata cuwezo 1.3 use different cuwezos. If a non-HDMI1.4 cuwezo is used in the HDMI1.4 system, the audio return and Ethernet functions will be lost. However, all the features of HDMI1.3 and other new features of HDMI1.4 (such as 3D) can be retained.

DisplayPortinafafanua aina mbili za viunganisho, Ukubwa Kamili na Mini. Viunganisho vyote vina pini 20, lakini upana wa kontakt mini ni karibu nusu ya saizi kamili, na vipimo vyake ni 7.5mm x 4.5mm na 16mm x 4.8mm, mtawaliwa. Ili kuanzisha kiunga kamili inahitaji jozi 5 za coaxial, ishara 3 za kumaliza moja, na nguvu na waya za ardhini.

Thescalability of DisplayPortCuwezo itself allows a low-bandwidth DisplayPortlink to be established with fewer wires, but few people do this because it may cause confusing compatibility issues for end users.

Theabove is the difference between the HDMIhigh-definition cuwezo signal and the DisplayPortcuwezo signal introduced by the technical staff of Edson. Although the HDMIdata cuwezo and DisplayPortseem to have the same function, they are also high-speed digital serial links, but in terms of structure, they It's completely different.
