Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev nrov nrov ntawm kev soj ntsuam cov tshuab, kev soj ntsuam network tau maj mam dhau los ua qhov tseem ceeb ntawm kev soj ntsuam. Qhov thib ob-tiam digital soj ntsuam lub koob yees duab yees duab soj ntsuam system yog tam sim no lub ntsiab video soj ntsuam system, nrog nws cov ntsiab lus siab thiab tsis tshua muaj peev xwm thiab khaws cia thiab tshuaj xyuas. Kev yooj yim tau tso cai rau nws txoj kev loj hlob thiab kev muaj koob meej loj hlob sai. Tam sim no nrog kev nce qib txuas ntxiv ntawm cov thev naus laus zis hauv network, qhov thib peb-tiam yees duab saib xyuas qhov system' tag nrho-digital network video soj ntsuam tau pib khiav mus rau hauv qhov chaw. Qhov txiaj ntsig loj tshaj plaws ntawm kev soj ntsuam video hauv network yog tias nws tsis tas yuav xaim thiab yooj yim los tswj. Nyob rau tib lub sijhawm, nrog kev txhim kho thev naus laus zis, cov txiaj ntsig tuaj yeem ua tiav mus rau qib thib ob ntawm kev soj ntsuam digital video. Hauv kev ua haujlwm tiag tiag, peb siv kev saib xyuas network thiab kev sib txuas hauv network raws li kev ua haujlwm tiag tiag. Txoj hauv kev los faib lub network video soj ntsuam system ua plaub hom:
Thawj yog kev sib koom ua ke hauv network chaw taws teeb saib xyuas siv cov koob yees duab analog saib + digital hard disk recorders + video servers
Txij li kev saib xyuas cov yeeb yaj kiab dawb huv hauv network tsis yog technically txaus kom ua tiav cov txiaj ntsig zoo, kev sib koom ua ke network chaw taws teeb saib xyuas siv cov koob yees duab analog saib + digital hard disk video recorders + video servers tau dhau los ua qhov tseem ceeb. Teeb tsa cov chaw nres nkoj, lub rooj vag thiab cov kev hauv cheeb tsam hauv cheeb tsam network, thiab siv cov video server hauv digital hard disk video recorder ua lub teeb liab saib, kom cov neeg siv tuaj yeem pom ib puag ncig lawv xav saib xyuas thiab kaw cov yeeb yaj kiab ntau txhiab mais deb. Nyob rau hauv txoj kev no, lub koob yees duab analog saib xyuas tseem yuav tsum tau xaim, thiab nws nyuaj rau kev nqis peev hauv kev saib xyuas.
Qhov thib ob yog ncaj qha siv lub koob yees duab analog + video server + network system
Lub analog video teeb liab ntawm lub koob yees duab yog hloov dua siab tshiab rau hauv lub teeb liab digital los ntawm video server, thiab ces compressed thiab encoded. Tom qab tso tawm, nplooj ntawv web uas tuaj yeem tshawb xyuas tau muab rau cov neeg rau zaub mov video, kom koj tuaj yeem saib nws los ntawm kev nkag mus rau IP chaw nyob hauv ib lub khoos phis tawj ntawm cheeb tsam hauv cheeb tsam network Saib xyuas daim duab thiab ua haujlwm tswj xws li zooming, zooming, thiab tig lub koob yees duab. Yog tias koj siv dynamic domain name daws teeb meem, koj tuaj yeem paub tias cov teeb liab video hauv cheeb tsam network tuaj yeem pom ntau txhiab mais deb.
Qhov thib peb yog txoj kev ntawm lub koob yees duab network + network system
Lub koob yees duab network tam sim no yog lub koob yees duab kev koom ua ke nrog cov neeg rau zaub mov video. Los ntawm lub built-in analog/digital conversion thiab video neeg rau zaub mov functions, network kev sib txuas lus thiab cov ntaub ntawv kis tau tus mob. Nws tuaj yeem siv ncaj qha los ntawm kev ntsaws rau hauv Internet cable. Nov yog lub koob yees duab hauv tsev tam sim no. Txoj kev loj.
Hom plaub yog kev soj ntsuam video siv 3G wireless networks
Kev kub ceev ntawm 3G network ua rau nws ua tau rau lub xov tooj txawb chaw taws teeb saib xyuas video. Lub koob yees duab duab yog compressed los ntawm video compression coding module, thiab tom qab ntawd 3G wireless module yog siv los paub txog kev sib cuam tshuam ntawm cov ntaub ntawv video, xa / txais, encryption thiab decryption, coding thiab decoding, txuas tswj thiab tu, thiab lwm yam. Muaj nuj nqi, tiag -lub sij hawm xa cov duab dynamic mus rau 3G kev sib txuas lus network, kom cov neeg siv khoom siv lub wireless 3G network los saib qhov chaw nyob deb txawm lawv nyob qhov twg. Qhov no muab kev yooj yim rau ntau daim ntawv thov xws li kev saib xyuas tej thaj chaw deb thiab kev mus ntsib tej thaj chaw deb.
