Menene HD Streaming?
Kalmar HD tana nufin Babban Ma'ana, kuma HD Streaming yana nufin ƙudurin bidiyo mai inganci HD wanda aka watsa akan intanet don sake kunnawa.Ana iya yi ta amfani da dama daban-daban video Formats, ciki har da MPEG ko santsi video streaming.
Abubuwan bidiyo masu yawo na HD zai ba ku ƙarin haske da dalla-dalla fiye da ƙudurin bidiyo na SD, galibi ana gani akan YouTube da sauran gidajen yanar gizo.Za ku ga ƙarancin pixelation a cikin babban abun ciki na bidiyo saboda yana da ninki biyu da yawa a kowane firam (1920×1080) fiye da ma'anar ma'anar ma'ana a 1280×720.Waɗannan hotuna masu inganci kuma suna da mafi kyawun haifuwar launi da motsi mai laushi saboda saurin firam ɗin su.
Ƙaddamar bidiyo a tsaye
1.SD tsarin bidiyo ne tare da ƙudurin jiki a ƙasan 720p (1280*720).720p yana nufin cewa ƙudurin bidiyo a tsaye shine layukan 720 na binciken ci gaba.Musamman, yana nufin tsarin bidiyo na “standard definition” kamar su VCD, DVD, da shirye-shiryen TV tare da ƙudurin kusan layi 400, wato daidaitaccen ma'anar.
2.Lokacin da ƙudurin jiki ya kai 720p ko sama, ana kiran shi high-definition (Ma'anar Turanci High Definition) ana magana da shi HD.Game da ma'auni masu girma, akwai wasu guda biyu da aka sani a duniya: ƙudurin bidiyo na tsaye ya wuce 720p ko 1080p;rabon bidiyon shine 16:9.
Bidiyo mai girma (HD) ba sabon abu bane a duniyar kayan lantarki na mabukaci inda aka sami babban canji daga Ma'anar Ma'anar (SD) zuwa mafi kyawun gani HD.
A fagen binciken masana'antu, sauyin ya kasance a hankali amma duk da haka, babu makawa.Duk da cewa yawancin tsarin dubawa da kyamarori a halin yanzu da ake samu akan kasuwa har yanzu sune Ma'anar Ma'anar, ƙwararrun masana sun yi hasashen cewa HD zai zama babbar fasaha ta 2020.
Hotunan launi sun ƙunshi ƙananan dige-dige da ake kira pixels, tare da ƙuduri yana nufin jimlar adadin pixels a cikin bidiyo ko hoto.Ma'anar bidiyo na SD yana farawa a 240p kuma yana ƙare a 480p, yayin da ƙudurin 1080p yana da ƙarfi HD (tare da wani abu sama da wannan ana ɗauka a matsayin Ultra-HD).

Yadda kyamara ke aiki:
1. Kamara ta ƙunshi ruwan tabarau, mai riƙe ruwan tabarau, capacitor, resistor, infrared filter (IP Filter), firikwensin (Sensor), allon kewayawa, guntu sarrafa hoto DSP da allon ƙarfafawa da sauran abubuwan haɗin gwiwa.
2. Akwai na'urori masu auna firikwensin iri biyu, daya shine firikwensin caji-coupled (CCD) dayan kuma karfen oxide conductor Sensor (CMOS);Da'irar allon gabaɗaya ana buga allon kewayawa (PCB) ko allon kewayawa (FPC).
3. Hasken wurin yana shiga cikin kyamarar ta cikin lens, sannan yana tace hasken infrared a cikin hasken da ke shiga cikin ruwan tabarau ta hanyar IR filter, sannan ya isa Sensor (sensor), wanda ke canza siginar gani zuwa siginar lantarki.
4. Ta hanyar na'urar analog / dijital ta ciki (ADC), ana canza siginar wutar lantarki zuwa siginar dijital, sannan a tura shi zuwa guntun sarrafa hoto DSP don sarrafawa, kuma a canza shi zuwa RGB, YUV da sauran nau'ikan don fitarwa.
