Ib yam li kev lag luam kev nyab xeeb ntawm Suav, kev lag luam hauv kev sib txuas lus hauv kev lag luam tau nkag tag nrho cov kev cai teev tseg hauv kev lag luam thiab cov tuam txhab kev lag luam hauv kev lag luam hauv xyoo tas los. Hauv particular, kev lag luam loj ntawm kev sib tham video video tau nthuav dav xyoo los ntawm xyoo hauv tsib xyoos dhau los. Nyob rau hauv 2009, kev lag luam loj ntawm kev lag luam hu 5.17 billion yuan, nce ntawm 22.22% tshaj ntawm 4.23 billion yuan nyob rau hauv 2008;

Kev ua lag luam ua rau HD xav tau

Nyob rau hauv xyoo tas los no, video conferencing system tau dhau los ua ib qho tseem ceeb rau kev ntsuas seb cov ntaub ntawv kev tsim kho ntawm ntau lub units yog ua tau li cas. Txawm li cas los xij, hauv cov koog uas tau siv cov rooj sib tham yees duab, peb niaj hnub hnov cov lus tsis txaus siab uas qhov kev hloov ntawm daim ntawv thov txawv ntawm qhov kev xav tau. Peb tuaj yeem pab tsis tau, tab sis nug, Dab tsi yog qhov cuam tshuam txog kev tsim kho video conferencing? Tej zaum nws yuav hais tias muaj coob tus neeg uas tau siv cov khoom siv sib tham ua ke yeej zoo li no. Thaum lub rooj sib tham, cov dluab ntawm cov neeg koom tsis meej txaus, thiab txawm tias ncua ntev ntev tshwm sim. Ib qho kev qhia ntawm tus neeg hais lus tuaj yeem pom tshwm tom qab ob peb feeb. Qhov tshwm sim ntawm cov teeb meem no yuav tsis ua rau cov kev sib tham video thiab qhov kev sib tham ntawm qhov kev sib tham, thiab txawm tias cov neeg siv tau hnov cov kev nyuaj siab nrog kev rov muaj teeb meem zoo li no. Qee qhov kev ntsuam xyuas qhia tau tias qhov tseeb, kev ncua, kev sib tw, kev ruaj ntseg, tus nqi siab thiab cov neeg tsav tsheb cov qauv kev nce qib yog txhua yam tseem ceeb hindering txoj kev lag luam ntawm kev sib tham video. Qhov teeb meem tseem ceeb tshaj plaws yog qhov pom meej ntawm qhov yees duab.

Suav cam video conferencing tau hloov tshiab. Ua ntej ua ntej HD encoding / decoding tshuab, Video conferencing cov ntaub ntawv yog encoded raws li Hom Kev Sib Hlis (CIF). Lub Koom Haum Thoob Ntiaj Teb Thoob Ntiaj Teb - Lub Tuam Thawj Cuam Tshaj Tawm tau tsim video qauv hu ua H.261 thiab H.263. H.261 tus qauv tsuas qhia txog QCIF thiab CIF hom ntawv. Lub quarter CIF (QCIF) hom ntawv tsuas yog siv rau cov rooj sib tham nrog cov nqi qis tshaj (64 kbit / s thiab tsawg dua) thiab tam sim no tsis tshua siv. Txij thaum kev tso tawm H.263 tus qauv, ntau dua "hom daws teeb meem" (4CIF thiab 16CIF) tau txais los lawm. Vim tias cov kev txwv ntawm kev sib tw thiab kev siv bandwidth thaum siv cov qauv no, cov kev daws teeb meem rau kev sib tham video tag nrho tseem yog CIF rau 4CIF. HD video conferencing kom tag nrho cov terminals yuav tsum HD tshaj, yog li ntawd tag nrho cov neeg koom hauv video conferencing yuav txaus siab HD yees duab. Tag nrho cov terminals yuav tsum txhawb kev nrawm qaum cov ntaub ntawv. Tsis tas li ntawd, network broadband yog qhov tseem ceeb tshaj plaws rau kev sib tham video zoo. High-txhais sib tham sib video conferencing yuav tsum tau tsawg kawg cov ntaub ntawv hloov cov nqi ntawm 1 Mbit / s.
