Mu kuyankhulana kwa mavidiyo ndi mavidiyo, khalidwe limatanthawuza ngati chochitikacho ndi chabwino kapena choipa. Kuphatikiza pa kufotokozera mwatsatanetsatane komwe timamva, monga 'zabwino kwambiri' kapena 'zoipa', pali njira yofotokozera khalidwe la mawu ndi mavidiyo. Icho chimatchedwa Mapeto Amalingaliro Opambana (MOS). MOS amapereka chiwerengero cha chiwerengero cha khalidwe lovomerezeka la atolandila atatha kulandira ndipo potsirizira pake akugwiritsidwa ntchito pogwiritsa ntchito codecs .
MOS amafotokozedwa mu nambala imodzi, kuyambira 1 mpaka 5, 1 kukhala yoyipa komanso yabwino kwambiri. MOS ndi ofunika kwambiri, chifukwa ndi zowerengeka zomwe zimachokera ku zomwe anthu amaziwona panthawi ya mayesero. Komabe, pali mapulogalamu a mapulogalamu omwe amayeza MOS pamakina, monga momwe tikuonera pansipa.
Mfundo Zogwirizana ndi Zomwe Zikugwirizana
Kutengedwa mu nambala zonse, nambala ndi zosavuta kuwerengera.
- 5 - Zangwiro. Monga kukambirana maso ndi maso kapena kulandira wailesi.
- 4 - Zabwino. Zolakwika sizingatheke, koma zomveka zimveka bwino. Izi ndi (zotchedwa) zamtundu wa mafoni.
- 3 - Kukhumudwitsa.
- 2 - zokhumudwitsa kwambiri. Zosatheka zosatheka kulankhulana.
- 1 - Simungathe kulankhulana
Miyezo siyenela kukhala nambala zonse. Malo ena ndi malire nthawi zambiri amawonetsedwa mu decimal zamtengo kuchokera ku spectrum iyi ya MOS. Mwachitsanzo, mtengo wa 4.0 mpaka 4.5 umatchulidwa ngati khalidwe labwino ndipo umapangitsa kukhutira kwathunthu. Izi ndizofunika mtengo wa PSTN ndi ma VoIP ambiri omwe amawunikira, nthawi zambiri ndi kupambana. Makhalidwe akugwera pansipa 3.5 akuyesedwa osavomerezeka ndi ogwiritsa ntchito ambiri.
Kodi MOS amayesedwa bwanji?
Nambala yambiri ya anthu imakhala ndipo imapangidwa kuti imve nyimbo zina. Mmodzi aliyense wa iwo amapereka chiwerengero kuchokera mkati mwa 1 mpaka 5. Kenaka masamu amatanthawuza (pafupifupi) amawerengedwa, kupereka Mapepala Opita Kumeneko. Poyesa MOS, pali mawu ena omwe akulimbikitsidwa kuti agwiritsidwe ntchito ndi ITU-T. Ali:
- Muyenera kukhala chete.
- Panalibe kanthu kowoneka.
- Iwo ankapembedza mafano amtengo.
- Ndikufuna mphindi ndi woyang'anira.
- Kodi iye amafunikira ndalama iliyonse?
Zomwe Zimakhudza Mbali Zoganizira Zomwe Zikugwirizana
MOS ikhoza kugwiritsidwa ntchito poyerekeza pakati pa mautumiki a VoIP ndi opereka. Koma chofunika kwambiri, amagwiritsidwa ntchito kuyesa ntchito ya codecs , yomwe imamvetsera nyimbo ndi mavidiyo kuti zisungidwe pamagwiritsidwe ntchito. Mayeso a MOS amapangidwira kwa codecs kudera linalake.
Komabe palinso zinthu zina zomwe zimakhudza mtundu wa mavidiyo ndi mavidiyo osamutsidwa, monga momwe tafotokozera m'nkhaniyi . Zinthu izi sizikuyenera kuwerengedwa muzofunikira za MOS, kotero pamene pakuzindikira MOS kwa codec, ntchito kapena intaneti, ndikofunikira kuti zinthu zina zonse zikhale zabwino kwambiri chifukwa cha khalidwe labwino, pakuti zikhalidwe za MOS zimaganiziridwa kuti apeze pansi pa zinthu zabwino.
Mapulogalamu Opanga Mapulogalamu Opanga Mapulogalamu
Popeza zolemba / zochitika za anthu za MOS zili zovuta komanso zosapindulitsa m'njira zambiri, pakali pano pali zipangizo zamakono zomwe zimayesa kuyerekezera MOS kuyendetsa voIP. Ngakhale kuti alibe vuto la munthu, chinthu chabwino ndi mayeserowa ndikuti amalingalira zonse zomwe zimadalira maukonde omwe angakhudze khalidwe la mawu . Zitsanzo zina ndi AppareNet Voice, Brix VoIP Measurement Suite, NetAlly, PsyVoIP ndi VQmon / EP.
