Vanhu vazhinji vanoyeuka kuti nhepfenyuro yeTV "Silicon Valley" ndeyemugadziri Richard
Hendrix, uyo netsaona akauya neshanduko yekumanikidza data algorithm uye akasarudza
gadzira yako yekutanga.
The series' consultants vakatokurudzira metric yekuongorora nayo
akafanana algorithms ndeyekunyepedzera Weissman Score.
Kuwedzera munyaya, yekutanga yakaita hurukuro yevhidhiyo vachishandisa iyi mhinduro.
Nharaunda inoremekedzwa inokokwa kuzokurukura imwe, isina kujairika zvachose
iyo musimboti wekumanikidza data kune odhiyo uye vhidhiyo kufona, iyo inogadzirisa dambudziko neitsva,
divi risingatarisirwi.
Kana iwe uchida kutora chikamu munhaurirano yemhinduro iyi, uye zvakare tsvaga kuti izvi zvinei zvakafanana
pfungwa naJonathan Swift uye mabasa Leo Tolstoy, ndapota pasi katsi.
Chimwe chezvinyorwa
Ngatitsanangure mune zvakajairika mashandiro emazuva ano kutaurirana kweaudio - musimboti wakafanana kune ese ari maviri
inofona pamusoro peiyo GSM network, pamwe chete nevatumwa nekukurumidza uye VOIP network.
Kudengenyeka kwenzwi kunotumirwa kumakrofoni ye smartphone, ipapo mune analog-digital
converter (ADC kana ADC):
Tevere, encoding inoitika neakasiyana macodecs (G711, G729, OPUS, GSM, nezvimwewo),
encryption inowedzerwa kana kusawedzerwa (SRTP, ZPTP, nezvimwewo) uye inotumirwa kunharaunda
kutumira data.
Semuyenzaniso, dzinenge dzese vatumwa pakarepo (WhatsApp, Viber, nezvimwewo) vanoshandisa macodecs akafanana (nguva pfupi yapfuura iyi inowanzo Opus), uye yakada kufanana zvishoma.
maprotocol akagadziridzwa (zvakavakirwa paSIP, WebRTC).
Iyo data yekufambisa network inogona kunge iri yeruzhinji Internet kana iyo GSM network kana
intranet:
Encryption chinhu chinosarudzika muchirongwa ichi, semuenzaniso muzviitiko zvakawanda zve
SIP telephony encryption haisi kushandiswa.
Asi muvatumwa, pane kudaro, ivo vanowanzo shandisa yavo yevaridzi
mapuroteni ezwi uye vhidhiyo encryption.
Tevere, iyo reverse process inoitika - mugamuchiri, agamuchira iyo data, anotema ruzivo rwakagamuchirwa, ipapo chiratidzo chinoenda kuDAC (digital-to-analog converter) uye obva apinda odhiyo amplifier yakabatana nemutauri:
Hunhu hwemazuva ano macodecs:
G.711 64 Kbps.
G.726 16, 24, 32 kana 40 Kbps.
G.729A 8 KB/sec.
GSM 13 KB/sec.
iLBC 13.3 KB/sec. (30ms furemu); 15.2 KB/sec. (20ms furemu)
Spex Range kubva 2.15 kusvika 22.4 KB/sec.
G.722 64 Kbps.
Saka, semuenzaniso, panguva yekukurukurirana kwemaminetsi manomwe paWhatsApp kana Skype pachava
Inenge 1 MB yakashandiswa.
Ngatirangarirei nhamba idzi - 1MB kwemaminetsi manomwe ehurukuro, tichadzida munguva pfupi.
"Leo Tolstoy akafanana negirazi ... rekuchinja ..."
Ngatiyeukei bhuku rinonyanya kuzivikanwa remunyori mukuru weRussia:
"Hondo uye Runyararo" ibhuku rakakurumbira rakanyorwa naLeo Nikolaevich Tolstoy, rinotsanangura chiRussian.
nzanga panguva yehondo naNapoleon muna 1805-1812. Epilogue yenovel inounza
nhoroondo kusvika 1820.
Bhuku rinonzi "War and Peace" rakanyorwa naL.N. Tolstoy akapedzera makore manomwe ebasa rakasimba uye rinopfuurira.
"Hondo neRunyararo": dura remunyori rine pamusoro pe5200 mapepa akanyorwa zvakanaka.
Kana iwe zvino wave kuda kuverenga chinyorwa ichi, unogona kuridhaunirodha zviri nyore.
Uye faira iri rinorema chete... 1 MB:
Iwo mafomati fb2 uye epub, senge zip, rar, musimboti, anogona kutariswa semhando ye
codecs
Ngatifungei nezvazvo - maminetsi manomwe ehurukuro yedu paWhatsApp akaenzana maererano nehuwandu hwetraffic
basa guru rakatora makore 7 kunyora!
Hurukuro ye7 maminetsi yakavharidzirwa neopus codec, iyo novel yakavharidzirwa nePub, vhoriyamu yakafanana -
1MB, asi mutsauko wakakura sei!
Gulliver's Travels
Munhu wose anoziva basa iri raJonathan Swift kubva paudiki, asi chaizvoizvo bhuku iri harisi re
vana.
Gulliver's Travels is satire yezvematongerwo enyika kune vanhu vakuru, hongu mumamiriro e18
zana remakore.
Chinhu chinoshamisa ndechekuti Swift, ari mupikisi ane hasha weimwe yenguva yake -
Newton, mu "Gulliver's Travels" haana kungofanotaura kuwanikwa kwemasatellite
Mars (ine tsananguro chaiyo yehunhu hwavo), asi zvakare yakatsanangura inonakidza
nzira yekukurukurirana pakati pevanhu:
β... chirongwa chaida kubviswa zvachose kwemashoko ose;
munyori wechirongwa ichi ainyanya kutaura nezvehutano hwayo uye mari yaakachengeta
nguva.
Pamusoro pazvo, zviri pachena kuti shoko rimwe nerimwe ratinotaura rine chokuita nokusakara.
mapapu uye, naizvozvo, zvinotungamirira kukuderedzwa kwehupenyu hwedu.
Uye sezvo mazwi ari mazita ezvinhu chete, munyori wepurojekiti anoita fungidziro iyoyo
kuti zvichava zvakatinakira zvikuru kuti titakure nesu zvinhu zvinodiwa kuti titaure zvedu
pfungwa nezvishuwo.
... vanhu vakawanda vakadzidza zvikuru uye vakachenjera vanoshandisa nzira itsva iyi yekutaura kwavo
pfungwa nerubatsiro rwezvinhu.
Kusagadzikana kwayo chete inyaya yekuti, kana zvichidikanwa,
kuitisa hurukuro yakareba pamisoro yakasiyana-siyana, vanopindirana vanofanira kutakura
mapendekete ane masumbu makuru ezvinhu, kana mari isingabvumiri kuhaya imwe kana
varume vaviri vakanaka. Ndaiwanzoona varume vaviri vakachenjera vakadaro, vaneta
mutoro unorema, sevatengesi vedu. Pavaisangana mumugwagwa, vakatora mifananidzo
mabhegi emapendekete, akaavhura uye, achibudisa zvinhu zvaidiwa kubva ipapo, nokudaro akaita hurukuro mukati
kuenderera kweawa; vakabva vaunganidza midziyo yavo ndokubatsirana kusimudza mutoro
mapendekete, ndokuonekana ndokuparadzana.
Nekudaro, pahurukuro pfupi uye dzakapfava unogona kutakura zvese zvaunoda muhomwe yako
kana pasi peruoko, uye kukurukurirana kunoitika kumba hakukonzeri chero
matambudziko. Naizvozvo, makamuri anoungana vanhu vanoshandisa nzira iyi anozadzwa nawo
marudzi ese ezvinhu akakodzera kushanda sezvinhu zvekugadzira zvakadaro
hurukuro.
Imwe mukana mukuru wechigadzirwa ichi ndechekuti inogona kushandiswa
somutauro wepasi rose, unonzwisiswa nemarudzi ose akabudirira, nokuda kwefanicha neimba
midziyo yacho yakafanana kana kuti yakafanana zvikuru kwose kwose, kuitira kuti kushandiswa kwavo kuve nyore kunzwisisa.
Saka, nhume dzinogona kutaura zviri nyore nemadzimambo edzimwe nyika kana
vashumiri vane mutauro vasinganyatsozivikanwi kwavari..."
Saka, pamwe unotofungidzira kwandiri kuenda neichi :)
Sei uchifambisa kudengenyeka kwemhepo (kutinhira) pamusoro pemazana nezviuru zvemakiromita?
kunetseka ne encoding (kuitira kuendesa aya kudengenyeka kwemhepo kune anogamuchira nenzira kwayo uye zvinobudirira sezvinobvira), chengetedza bandwidth inodiwa, kana semantic.
Kuremerwa kwekutapurirana uku kushoma here, kana kutosvika zero?
Mushure mezvose, vanhu vanotaurirana kwete nemanzwi, asi nezvazvinoreva, zvemukati, semantics, pfungwa ...
Pfungwa yeiyo nyowani yekutaurirana system iri nyore - padivi rekunobva A pane odhiyo
mavibrations anoiswawo digitaalinen, asi haasi pakarepo kuendeswa kune rimwe bato, asi
anoshandurwa kuita mavara (Speech To Text) uyezve zvinyorwa zvine musoro kubva
munyoreri A, uyo:
- inogona kufambiswa neiyo shoma inodiwa data bandwidth (kunyangwe HF redhiyo kutaurirana kunogoneka, nezvimwewo)
- inogona kuvharirwa nechero yakasimba encryption algorithm
Padivi B, mameseji anogamuchirwa anodzikiswa uye anodhindwa sezwi kubva
munyoreri A (Chinyorwa Kutaura).
Iwe unogona zvakare kudhawunirodha inonzi B side. izwi avatar yemunyoreri A, angaite
zvakanyatsodzokorora matauriro emunyoreri A.
Imwe nzira yakaparadzana inogona kuendesa kumashure ruzha uye manzwiro.
Zvakafanana ndezvechokwadi pakukurukurirana kwevhidhiyo - kunyanya sezvo zvinhu zvega zvagara zviripo
zviripo mumashandisirwo (masiki akasiyana, kumashure muZoom, nezvimwewo).
Ehe, pane tekinoroji zvinhu izvo parizvino zvisati zvaitwa zvizere muchimiro chakakodzera -
semuenzaniso, kumhanya kweS Speech To Text kutendeuka kuchave kwakaoma, asi kushandisa
Predictive AI yekushandura algorithms inogona kuwedzera zvakanyanya kumhanya uku.
Iyo inonyanya kukosha mukana ndeyekuti shoma bandwidth inodiwa mune yekufambisa svikiro
data.
Avo. Iyi nheyo inogona kushandiswa kwete yemazuva ose chete
kutaurirana, asiwo kwemauto uye kure-kure kutaurirana nekunonoka kwenguva refu
(kutaurirana muchadenga, interplanetary - Mwedzi, Mars, nezvimwewo :)
Kunyangwe iyi iri tsananguro yepfungwa, kutaura zvazviri, mune imwe yemapurojekiti edu pane atove akati wandei
A prototype ine musimboti uyu yave kushandiswa kwemwedzi.
Asi zvakawanda pamusoro peiyo nguva inotevera ...
