HDMI Encoders

HDMI encoder chishandiso chinoshandura masaini evhidhiyo akajairwa kuita fomu redhijitari iro rinogona kugadziriswa nekufambiswa pamanetiweki akadai seEthernet kana waya isina LAN. Inoshandiswa kufambisa zvemukati zvevhidhiyo kubva kune sosi mudziyo sePC kana set-yepamusoro bhokisi kune chiratidziro chishandiso seTV kana chekutarisa. Inoshanda nekushandura analog vhidhiyo masaini kubva kune sosi mudziyo kuita dhijitari vhidhiyo hova, iyo inobva yamanikidzwa uye inofambiswa pamusoro petiweki. Iye anogamuchira anobva asarudza rwizi uye anotumira kune chiratidziro chishandiso. HDMI encoders yakakosha nekuti inobvumidza kuti masaini edhijitari uye vhidhiyo masaini kuti ashandurwe kubva kuanalogi kuenda kudhijitari kuitira kuti afambiswe uye kuratidzwa pamidziyo yakaita sematerevhizheni nemamonitor. Iyo HDMI encoder inogona zvakare kubvumira kuti akawanda maturusi abatanidzwe kune imwe HDMI chiteshi, izvo zvinoita kuti zvive nyore kubatanidza akawanda maturusi pamwechete.

Chii chinonzi HDMI encoder chinoshandiswa?
HDMI encoders inonyanya kushandiswa mumavhidhiyo ekutepfenyura maapplication, vhidhiyo musangano, digital signage, uye IPTV kutepfenyura. Aya ma encoders anotora HDMI yekupinda kubva kune sosi mudziyo, senge kamera, laptop, kana DVR, uye inoiisa mufomati inogona kufambiswa painternet. Rukova rwunozobuda runogona kudhindwa pamudziyo weanogamuchira, senge komputa kana kuridza midhiya inoridza, ichibvumira kuti ionekwe pamonitor kana TV.
Ndezvipi zvakanakira HDMI encoder pamusoro pevamwe?
Zvakanakira zveHDMI encoder pamusoro pemamwe marudzi ehardware encoder anosanganisira:
1. Yepamusoro-mhando yevhidhiyo kutenderera ine kushoma latency uye yakaderera bitrate.
2. H.264 uye H.265 tsigiro yekutsikirira kwepamusoro, ichibvumira mifananidzo yemhando yepamusoro pamasaizi akaderera efaira.
3. Hapana kudiwa kwekadhi rekutora kunze, sezvo vazhinji veHDMI encoders vanouya neakavakwa-mukati mavhidhiyo ekutora makadhi.
4. Tsigiro yezvisarudzo zvakawanda, kusanganisira 4K uye 1080p.
5. Kuenderana neWindows uye Mac masisitimu anoshanda.
6. Mutengo-kushanda, sezvo HDMI encoders inodhura kupfuura mamwe marudzi eencoder hardware.
7. Compact uye portable design, zvichiita kuti zvive nyore kufamba uye kutakura.
8. Yakavakwa-mukati maficha akadai sedhidhiyo kusanganisa uye vhidhiyo switching kuti iwedzere kuchinjika panguva yekutenderera.
Chii chinonzi chiteshi huwandu (semuenzaniso 4 kana 8-chiteshi) chinorevei kune HDMI encoder?
4-channel uye 8-channel inoreva nhamba yemavhidhiyo masaini ayo HDMI encoder inogona kugadzirisa kamwechete. Iyo yakakwira huwandu hwezviteshi, iyo yakawanda vhidhiyo masaini iyo encoder inogona kugadzirisa kamwechete. Paunosarudza pakati pematanho akasiyana eHDMI encoders, zvakakosha kuti utarise huwandu hwemasaini evhidhiyo aunozofanirwa kugadzirisa kamwechete. Kana iwe uchingoda chete kugadzirisa mashoma evhidhiyo masaini, ipapo 4-chiteshi encoder inogona kukwana. Nekudaro, kana iwe uchida kugadzirisa mamwe masaini evhidhiyo, ipapo 8-chiteshi encoder inogona kunge yakakodzera.
Maitiro ekusarudza HDMI encoders zvichibva pane akasiyana maapplication?
1. Live Video Streaming Applications: Paunosarudza HDMI encoder yehupenyu huripo, funga nezvekugadzirisa uye furemu chiyero chaunoda, pamwe chete nezvimwe zvekuwedzera zvakadai sekusanganisa audio, kuyera vhidhiyo, uye HDR rutsigiro. Pamusoro pezvo, tsvaga encoder ine yakaderera latency, yakavimbika kutenderera, uye nyore kuseta.

2. Vhidhiyo Conferencing Applications: Pazvikumbiro zvemusangano wevhidhiyo, tsvaga HDMI encoder inotsigira akawanda panguva imwe chete mavhidhiyo uye maodhiyo streams, pamwe neakawanda sarudzo dzekushambadzira. Pamusoro pezvo, funga nezve encoder inotsigira maficha epamberi emusangano senge kurekodha, kurekodha maneja, uye otomatiki switching.

3. Kutepfenyura Zvishandiso: Pakusarudza HDMI encoder yezvikumbiro zvekutepfenyura, tsvaga encoder inotsigira zvese zviri zviviri resolution yepamusoro uye yakakwirira furemu kuyerera. Pamusoro pezvo, tsvaga encoder ine maficha akadai seyevhidhiyo kuyera, kusanganisa odhiyo, uye HDR rutsigiro.

4. Game Streaming Applications: Pamitambo yekufambisa mitambo, tsvaga HDMI encoder ine low latency uye yakavimbika kutenderera. Pamusoro pezvo, funga encoder inotsigira akawanda ekutepfenyura sarudzo uye epamberi maficha senge odhiyo kusanganisa, kuyera vhidhiyo, uye HDR rutsigiro.
Chii chaunofanira kutarisira usati watenga HDMI encoder?
Izvo zvakakosha zvakatemwa zveHDMI encoder izvo vatengi vane hanya nazvo ndeye resolution, furemu chiyero, bit rate, vhidhiyo codec, audio codec, synchronous video/odhiyo, uye network transmission protocol. Zvimwe zvinhu zvakakosha zvekufunga nezvazvo zvinosanganisira latency, scalability, smart H.264 encoding, kuenderana nemafomati aripo, uye kugona kwesimba.
Kunze kwezvo, iwe unofanirwawo kutevera matanho aya:
Danho 1: Ziva zvaunoda. Funga zvinhu zvakaita segadziriso, odhiyo, uye mhando yevhidhiyo, pamwe nemhando yechishandiso uye sisitimu yaunoronga kushandisa.
Danho 2: Tsvakurudza akasiyana encoders eHDMI uye enzanisa maitiro avo. Tsvaga mamwe maficha akadai sekushambadzira, transcoding, uye kugona kurekodha.

Danho rechitatu: Funga nezve mutengo weiyo encoder. Enzanisa mitengo pakati pemhando dzakasiyana kuti uwane iyo yakanakisa dhiri.

Nhanho 4: Verenga wongororo yevatengi uye zviyero. Izvi zvinokupa iwe pfungwa yekuti vatengi vanogutsikana sei nechigadzirwa.

Danho 5: Sarudza HDMI encoder inonyatso kuzadzisa zvaunoda uye bhajeti.
Mangani marudzi eprotocol aripo eHDMI encoder uye maitiro ekusarudza pakati uye nei?
Kune marudzi maviri eHDMI encoder protocol: HD-SDI uye IP. Sarudzo pakati pemaprotocol maviri inoenderana nekushandiswa uye zvinodiwa nemushandisi. HD-SDI inoshandiswa kutepfenyura yakakwira-tsanangudzo vhidhiyo uye odhiyo uye ndiyo inofarirwa protocol yekushambadzira maapplication. IP kutenderera kwakakodzera kune yakaderera-bandwidth application uye inodhura-inoshanda.
Ndeapi marudzi ekugadzirisa aripo eHDMI encodera uye maitiro ekusarudza pakati uye nei?
Kune marudzi maviri ekugadziriswa kweHDMI encoder: 1080p uye 4K. Paunosarudza pakati pezviviri, zvakakosha kufunga nezvehutano hwemufananidzo waunoda. 1080p ine yakakwira furemu chiyero, asi yakaderera resolution, nepo 4K ine yakakwirira resolution, asi yakaderera furemu chiyero.
Ungasarudza sei pakati peH.265 HDMI encodera neH.264 HDMI encoder uye nei?
Pakusarudza pakati peH.265 HDMI encoder neH.264 HDMI encoder, zvakakosha kuti utarise kunaka kwevhidhiyo, bitrate, uye kuenderana. H.265 ndiyo itsva uye yakanyanyisa kodeki, uye inopa kunaka kwevhidhiyo iri nani pane yakaderera bitrate, zvichireva kuti inogona kuchengetedza pabandwidth uye kuchengetedza. Zvisinei, H.265 haienderani zvakanyanya seH.264, saka zvakakosha kuti utarise kuenderana kwemidziyo yauri kushandisa. Pakupedzisira, zvinouya pasi kune iyo codec inopa yakanyanya kunaka kuita kune zvaunoda chaizvo.
