Since1964,theworld’sfirstanalogtechnologyvideophonepicturephoneMOD-IwasborninBellLabs,USASincethen,thetechnologyandcorrespondingstandardsinthefieldofvideoconferencinghavebeenincontinuousdevelopment.Ingeneral,videoconferencinghasmainlyexperiencedthreestages:analogvideoconferencing,digitalvideoconferencing,andinternationallyunifieddigitalvideoconferencing.
Inthe1960s,developedcountriesbegantostudyanalogvideoconferencingandgraduallycommercializedit.Earlyvideoconferencingsystemsweretransmittedinananalogmanner.Althoughonlyblackandwhiteimagesweretransmittedandconfinedbetweentwolocations,videoconferencingstilltookupalotofbandwidthandwasexpensive,soitwasnotdeveloped.ItsrepresentativesincludethevideophoneofBellLabsintheUnitedStates,whichwasfirstdevelopedintheUnitedStates,andthe1MHZbandwidthblackandwhitevideoconferenceofBTintheUnitedKingdom.Bythemid-1970s,thedigitalimageandspeechcodingtechnologyhadmadegreatprogress,makingtheanalogsystemgraduallyturntothedigitalsystem.However,sinceearlyvideoconferencingdidnothaveaunifiedstandard,theywereallimplementedonthebasisoftheirownresearchanddevelopmenttechnologies,makingitdifficultforvariousvideoconferencingproductstoachieveinteroperability.

Usingvideoconferencing,youcancommunicatewithmultiplepeopleatthesametime,andpeoplecanalsotalkface-to-face.Inofficesandeducationalinstitutionsaroundtheworld,videoconferencingcanalsobeusedforlearning,training,andmeetingwithcontactswithouttheneedfortravel.Videoconferencingcannotonlysavephonebills,butalsohelpimprovetheenvironmentandreducebusinessexpensesinarrangingemployeestogooutformeetings.Inaddition,friendsandfamilycanusevideoconferencingtokeepintouchwithrelativeslivinginothercountries,andevensoldiersfightingoverseascanalsousevideoconferencingtokeepintouchwiththeirlovedonesathome.Videoconferencingsolutionsarefeasibleduringtheeconomicdownturn,andareakeyapplicationwhentheeconomyimproves.ThepreviouseconomicrecessionhasshownthatcompaniesthatinvestedinITandcommunicationsduringtheeconomiccrisiswillbeinastrongcompetitivepositionaftertheeconomicstormhaspassed,andwillevenbeabletoseizemarketsharefromtheircompetitors.ForthosecompaniesthatarecapableandwillingtocontinueinvestinginITduringtherecession,visualcommunicationandcollaborativeproductsandservicesshouldbeacorepartoftheirsurvivalstrategy.Thiskindofinvestmentwillputthesecompaniesinafavorablecompetitivepositionwhentheeconomyrecovers.Withthedevelopmentofsociety,theapplicationofvideoconferencinghasbecomemoreandmoreextensive,andtherequirementsforvideoandaudioquality,datacollaborationandsharing,flexibilityandeaseofuse,andeaseofmanagementhavebecomemoreandmorestringent.Earlyvideoconferencingsystemsareusuallyconstructedintheformofdedicatedhardwaredevices,includingamultipointcontrolunitMCUandvideoterminals,andtheymustbeconnectedtoeachotherthroughaprivatenetwork.Thehighcostofhardwareandprivatenetworksrestrictshardwarevideoconferencingsystemsthatcanonlybeusedinthegovernment,military,andlargeenterprisegroups,anditisdifficulttopopularizesmallandmedium-sizedenterprisesanddailyapplications.Withtheimprovementofcomputerprocessingcapabilitiesandsoftwaretechnology,videoconferencingsystemshavealsobeguntodevelopsoftware.Moreandmoresoftwareproductsbasedontheserver/clientmodelhaveappeared.Videoconferencingisusedforofficecommunication,businesstraining,marketing,etc.Thefieldisexpanding,andthisrelativelylow-costandconvenientapplicationisgraduallybeingacceptedbymostsmallandmedium-sizedenterprisesandinstitutions.Networkvideoconferencingisthelatestdevelopmentofsoftwarevideoconferencing.ItiscompletelybasedontheInternetandsupportsglobal-orientedcollaborativework.Atthesametime,itisusedinthemostcommonlyusedbrowsermodeintheInternetera,whichgreatlyexpandstheapplicationscenariosandlocations.

Trend1:Theintegrationofsoftwareandhardwarevideoconferencing
Inordertomeettherequirementsofmeetinganytime,anywhere,andtakingintoaccounttheultimateWiththeneedsofenterpriseusersinhigh-definitionandvirtualrealvenues,softwarevideoconferencingandhardwarevideoconferencing(remotepresentation)willmovetowardsconvergence.Thedevelopmentoffusionconferencewillgothroughthreestages.

Trend2:Low-bandwidthandhigh-qualityaudioandvideo
Withthedevelopmentofvoicecodectechnology,conferencevoicewilldevelopintobroadbandandmulti-channel:8KHzmonoà22KHzstereoà22KHzmulti-channelàvirtualsoundfield.Atthesametime,whenthedesktopterminalaccessesthemeetingfromthepublicnetwork,itcanuseintelligentalgorithmstogivethebestcodingandtransmissionschemethatadaptstothecurrentnetworkaccordingtothenetworktransmissionqualityandthenetworkmodel,soastoensurethatthenetworkcanstillbechangedwhenthenetworkchanges.Provideuserswithagoodbusinessexperience.Forexample,whenthenetworkdeteriorates,low-bandwidthvoicecodecisintelligentlyusedtoensurenormalvoicecalls;whenthenetworkimproves,broadbandcodecisusedtoimproveuserexperience.Moreimportantly,duringthischangeprocess,thevoicequalitycanbesmoothlychanged.

Trend3:SharingandCollaboration
Withthecontinuousdevelopmentofmodernenterprises,cross-regionalvirtualteamshavebecomethenorm,whichhasalsopromptedmeetingstoshiftfromcommunication-centrictoSharingandcollaborationarecentered.Traditionalhardwarevideoconferencesrealizevoiceandvideoinformationcommunication.Softwarevideoconferencesintroducedatacollaborationcapabilitiesonthebasisofaudioandvideo,whichcanprovidecollaborationfunctionssuchasscreensharing,documentsharing,electronicwhiteboard,textchat,andelectronicvoting.Ithasnotyetprovidedfunctionssuchasdissemination,classification,search,many-to-manyasynchronoussharingandcollaborationofconferencecontent,anditscollaborationcapabilitiesneedtobefurtherexpanded.
Combinedwiththeinformationdisseminationmethodsofsocialnetworks,"meetingspace"willbeintroducedintotheconferencesystemtorealizethedisseminationandsharingofconferencecontent.TheconferenceorganizerorparticipantscanuploadandsendtheconferencematerialsbeforetheconferenceMeetingnotificationsaregiventoparticipantstounderstandthesubjectofthemeetinginadvance.Documentscanbemodifiedandnewversionscanbeuploadedbasedonpermissions.Participantsareautomaticallyremindedofdocumentupdates;

Afterthemeeting,themeetingmaterials,meetingVideorecordingsandmeetingminutesareclassifiedandidentified,andtheyareavailableforon-demandanddownload,andadiscussionspaceisprovidedforsubsequentdiscussionsandexchangesinthemeeting.Thus,informationdisseminationcanbeachievedonthebasisofinformationcommunication,andthesharingandcollaborationofvirtualteamsoftheenterprisecanberealized.
Trend4:Simpleandfastmeetingexperience
Withtheapplicationofvariousnewtechnologies,meetingfunctionshavebecomemoreandmorepowerful,butTheuser'sconferenceserviceexperienceshoulddevelopinamoreconvenientandefficientdirection.Theuseofconferenceservicesmainlyincludestwoscenarios:conferencecallingandconferencejoining.Whenconveningameeting,inadditiontobeingabletologintoPortaltomakemeetingreservations,itcanalsobeintegratedwithUCandothermainstreamenterpriseapplicationsoftware.Itcanbeinitiatedbyone-clickthroughUCsoftterminal,Outlook,Notes,Office,enterpriseOAorotherapplicationsoftwareclientsConvenemeetingstomakethemeetinghabitsconsistentwiththeuseofotherofficesoftware.Forexample,whenauserreceivesanemailandwantstodirectlyconveneameetingtodiscussatopic,hecandirectlyclickthebuttontoinitiateameetingintheemailtoconvenethemeeting.Thesystemautomaticallyusesthesubjectoftheemailasthesubjectofthemeeting,andthecontentoftheemailasthemeetingmaterials.Thesenderandallrecipientsserveasconferencemembersandmakeconferencereservations,soastorealizetheemotionallyawareconferencecall.
