Imidiya yokusakaza ividiyo kanye / noma idatha yomsindo idluliselwa phezu kwenethiwekhi yekhompyutha yokudlala ngokushesha kunokuba ilayishwe ifayela futhi kamuva (ungaxhunyiwe ku-intanethi) ukudlala. Izibonelo zokusakaza ividiyo nomsindo kufaka phakathi umsakazo we- intanethi kanye nokusakazwa kwethelevishini, namabhulogi wewebhu webhizinisi.
Ukusebenzisa ukusakaza imidiya
Ukuxhumana kwenethiwekhi ye- bandwidth ephezulu kudingekile ukuthi kusebenze ngemidiya yokusakaza. Izidingo ezicacile zomkhawulokudonsa kuxhomeke kuhlobo lokuqukethwe. Isibonelo, ukubheka ividiyo yokusakaza yokusombululo eliphezulu kudinga ukuhamba komkhawulokudonsa okuningi kunokuba ubukele ividiyo ephansi-yokuxazulula noma ukulalela ukusakaza komculo .
Ukuze ufinyelele imifudlana yemidiya, abasebenzisi bavula abadlali babo bomsindo / bevidiyo kwikhompyutheni yabo bese baqala uxhumano kwisistimu yesiphakeli . E-inthanethi, la maseva wemidiya ingaba amaseva weWebhu noma amadivaysi azinhloso ezikhethekile ahlelwe ngokukhethekile ekusakazeni okuphezulu.
I-bandwidth (i-throughput) yomsakazo wezindaba isilinganiso sayo esincane . Uma inani elincane ligcinwa kwinethiwekhi yomsakazo onikeziwe wehla ngaphansi kwesilinganiso esidingekayo ukusekela ukudlala okusheshayo, kwehla amafomethi wevidiyo kanye / noma ukulahlekelwa kwemiphumela yomsindo. Amasistimu wezindaba zokusakaza ngokuvamile asebenzisa ubuchwepheshe bokucindezela idatha yangempela-sikhathi ukwehlisa inani lomkhawulokudonsa elisetshenziselwa uxhumano ngalunye. Ezinye izinhlelo zokusakazwa kwezindaba zingasungulwa ukuze zisekele i- Quality of Service (QoS) ukusiza ukugcina ukusebenza okudingekayo.
Ukusetha Amakhompiyutha Wekhompyutha ye-Streaming Media
Izivumelwano ezithile zenethiwekhi zenziwe ngokukhethekile ekusakazeni imidiya, kufaka phakathi i- Real Time Streaming Protocol (RTSP) . I-HTTP ingasetshenziswa futhi uma okuqukethwe okusakazwa kuqukethe amafayela agcinwe kwi-Web server. Izinhlelo zokusebenza zabadlali bezindaba ziqukethe ukwesekwa okuzakhelwe ngaphakathi kwezinhlelo ezidingekayo ukuze abasebenzisi ngokuvamile badinga ukushintsha noma yiziphi izilungiselelo kwikhompyutha yabo ukuthola imilayezo yomsindo / yevidiyo.
Izibonelo zabadlali bezindaba zihlanganisa:
- I-QuickTime
- I-RealPlayer
- I-Windows Media Player
Abahlinzeki bokuqukethwe abafuna ukuletha imifudlana bangasetha imvelo yeseva ngezindlela ezihlukahlukene:
- Bhalisela kwenye yezinsiza zewebhu zokusakazwa bukhoma bukhoma njenge-justin.tv noma ustream.
- Yakha isiphakeli semidiya yangasese ye-intanethi ngokufaka isofthiwe ekhethekile yokuhweba kwi-Web server. Izibonelo zesofthiwe yesiphakeli semidiya zifaka i-RealNetworks Helix Server ne-Adobe Flash Media.
