Anthu ambiri amakumbukira kuti TV wakuti "Silicon Valley" ndi za wolemba mapulogalamu Richard
Hendrix, yemwe mwangozi adabwera ndi njira yosinthira data ndikusankha
kupanga chiyambi chanu.
Alangizi a mndandandawu adaperekanso ma metric oti aunike nawo
ma aligorivimu ofanana ndi opeka Weissman Score.
Kupitilira munkhaniyi, oyambitsa adapanga macheza amakanema pogwiritsa ntchito yankho ili.
Anthu olemekezeka akuitanidwa kuti akambirane zina, zachilendo kwambiri
mfundo ya kukakamiza kwa data pama foni omvera ndi makanema, omwe amathetsa vutoli ndi yatsopano,
mbali yosayembekezeka.
Ngati mukufuna kutenga nawo mbali pazokambirana za yankho ili, komanso fufuzani zomwe zikufanana
malingaliro ndi Jonathan Swift ndi ntchito za Leo Tolstoy, chonde pansi pa mphaka.
Chiphunzitso china
Tiyeni tifotokoze mwachidule momwe kuyankhulana kwamakono kumagwirira ntchito - mfundoyi ndi yofanana kwa onse awiri
kuyimbira pa netiweki ya GSM, komanso ma messenger apompopompo ndi maukonde a VOIP.
Kugwedezeka kwamawu kumatumizidwa ku maikolofoni ya foni yamakono, kenako mu analog-digital
Converter (ADC kapena ADC):
Kenako, encoding imachitika ndi ma codec osiyanasiyana (G711, G729, OPUS, GSM, etc.),
kubisa kumawonjezedwa kapena kusawonjezedwa (SRTP, ZPTP, etc.) ndikutumizidwa ku chilengedwe
kutumiza deta.
Mwachitsanzo, pafupifupi amithenga onse apompopompo (WhatsApp, Viber, etc.) amagwiritsa ntchito ma codec omwewo (posachedwapa nthawi zambiri amakhala Opus), ndipo pafupifupi ofanana pang'ono.
ma protocol osinthidwa (kutengera SIP, WebRTC).
Netiweki yotumizira deta ikhoza kukhala intaneti yapagulu kapena netiweki ya GSM kapena
intaneti:
Kubisa ndi chinthu chosankha mu dongosololi, mwachitsanzo nthawi zambiri za
SIP telephony encryption sikugwiritsidwa ntchito.
Koma mwa amithenga, m'malo mwake, nthawi zambiri amagwiritsa ntchito eni ake
ma protocol amawu ndi makanema akabisa.
Kenako, njira yosinthira imachitika - wolandila, atalandira zidziwitsozo, amazindikira zomwe adalandira, ndiye chizindikirocho chimapita ku DAC (chosinthira digito-to-analog) ndikulowetsa mawu amplifier olumikizidwa ndi wokamba:
Makhalidwe a ma codec amakono:
G.711 64 Kbps.
G.726 16, 24, 32 kapena 40 Kbps.
G.729A 8 KB/mphindi.
GSM 13 KB/mphindi.
iLBC 13.3 KB/mphindi. (30ms chimango); 15.2 KB / mphindi. (20ms chimango)
Zosiyanasiyana Zosiyanasiyana kuchokera ku 2.15 mpaka 22.4 KB / mphindi.
G.722 64 Kbps.
Chifukwa chake, mwachitsanzo, pakukambirana kwa mphindi 7 pa WhatsApp kapena Skype padzakhala
Pafupifupi 1 MB idagwiritsidwa ntchito.
Tiyeni tikumbukire manambala awa - 1MB kwa mphindi 7 zokambirana, tidzazifuna posachedwa.
"Leo Tolstoy ali ngati galasi ... la revolution ..."
Tiyeni tikumbukire buku lodziwika kwambiri la wolemba wamkulu waku Russia uyu:
"Nkhondo ndi Mtendere" ndi buku lodziwika bwino la Leo Nikolaevich Tolstoy, kufotokoza Russian
anthu pankhondo yolimbana ndi Napoleon mu 1805-1812. Epilogue ya novel imabweretsa
nkhani mpaka 1820.
Buku la "War and Peace" lolembedwa ndi L.N. Tolstoy anathera zaka 7 akugwira ntchito mwakhama ndiponso mosalekeza.
"Nkhondo ndi Mtendere": zolemba zakale za wolemba zili ndi mapepala olembedwa bwino opitilira 5200.
Ngati mukufuna kuwerenga bukuli, mutha kulitsitsa mosavuta.
Ndipo fayiloyi imalemera kokha... 1 MB:
Mawonekedwe a fb2 ndi epub, monga zip, rar, kwenikweni, amatha kuonedwa ngati mtundu wa
kodi
Tiyeni tiganizire za izi - mphindi 7 za zokambirana zathu pa WhatsApp ndizofanana ndi kuchuluka kwa magalimoto
ntchito yayikulu yomwe idatenga zaka 7 kuti ilembe!
Kukambirana kwa mphindi 7 kudasindikizidwa ndi opus codec, bukuli lidasindikizidwa ndi ePub, voliyumu yake ndi yofanana -
1MB, koma kusiyana kwakukulu bwanji!
Maulendo a Gulliver
Aliyense amadziwa ntchito iyi ya Jonathan Swift kuyambira ali mwana, koma kwenikweni bukuli siloyenera
ana.
Gulliver's Travels ndi nthabwala zandale kwa akulu, zomwe zili mu 18
zana.
Chodabwitsa ndichakuti Swift, pokhala wotsutsa kwambiri wanthawi yake ina -
Newton, mβbuku lake lakuti βGulliverβs Travelsβ sanangoneneratu za kupezeka kwa ma satellite
Mars (ndi kufotokoza momveka bwino makhalidwe awo), komanso anafotokoza m'malo chidwi
njira yolumikizirana pakati pa anthu:
β... ntchitoyo inafuna kuti mawu onse athetsedwe;
mlembi wa polojekitiyi anatchula makamaka za ubwino wake pa thanzi ndi ndalama
nthawi.
Ndipotu, nβzoonekeratu kuti mawu alionse amene timalankhula amagwirizana ndi kungβambika.
mapapu ndipo, motero, kumabweretsa kuchepa kwa moyo wathu.
Ndipo popeza mawu ndi mayina azinthu zokha, wolemba ntchitoyo akuganiza kuti
kuti kudzakhala kosavuta kwambiri kwa ife kunyamula zinthu zofunika kufotokoza zathu
maganizo ndi zokhumba.
...anthu ophunzira kwambiri ndi anzeru amagwiritsa ntchito njira yatsopanoyi yofotokozera awo
maganizo mothandizidwa ndi zinthu.
Choyipa chake ndi chakuti, ngati kuli kofunikira,
kambiranani nthawi yayitali pamitu yosiyanasiyana, olankhula nawo ayenera kunyamula
mapewa ndi mitolo lalikulu la zinthu, ngati ndalama salola kulemba ganyu kapena
anyamata awiri olemera. Nthawi zambiri ndinkaona amuna awiri anzeru oterowo atatopa kwambiri
katundu wolemetsa, monga ogulitsa athu. Akakumana mumsewu ankajambula zithunzi
mapewa matumba, anatsegula ndi, kutenga zofunika kuchokera kumeneko, motero anapitiriza kukambirana
kupitiriza kwa ola; kenako adaunjika ziwiya zawo ndikuthandizana kunyamula katundu
mapewa, anatsazikana ndipo anasiyana njira.
Komabe, pazokambirana zazifupi komanso zosavuta mutha kunyamula chilichonse chomwe mungafune m'thumba lanu
kapena pansi pa mkono, ndipo kukambirana kukuchitika kunyumba sikuyambitsa
zovuta. Choncho, zipinda zomwe anthu ogwiritsira ntchito njirayi amasonkhana zimadzaza
mitundu yonse ya zinthu zoyenera kutumikira ngati chuma chochita kupanga
zokambirana.
Ubwino winanso waukulu wopangidwa ndi izi ndikuti ukhoza kugwiritsidwa ntchito
monga chilankhulo chapadziko lonse lapansi, chomveka kumitundu yonse yotukuka, ya mipando ndi nyumba
ziwiya ndi zofanana kapena zofanana kwambiri kulikonse, kotero kuti ntchito yawo imveke mosavuta.
Motero, nthumwi zingathe kulankhula mosavuta ndi mafumu akunja kapena
atumiki omwe chilankhulo chawo sichidziwika kwa iwo ... "
Chifukwa chake, mwina mukuganiza kale komwe ndikupita ndi izi :)
Chifukwa chiyani kufalitsa kugwedezeka kwa mpweya (maphokoso) pamtunda wamakilomita mazana ndi masauzande?
kuvutitsidwa ndi encoding (kuti mupereke kugwedezeka kwa mpweya kwa wolandirayo molondola komanso moyenera momwe mungathere), sungani bandwidth yofunikira, ngati semantic
Kodi katundu wamtunduwu ndi wocheperako, kapena amafikira ziro?
Kupatula apo, anthu amalankhulana wina ndi mnzake osati ndi mawu, koma ndi tanthauzo, zomwe zili, semantics, malingaliro ...
Lingaliro la njira yatsopano yolankhulirana ndi yosavuta - pa gwero A pali zomvera
ma vibrations amasinthidwanso pa digito, koma samatumizidwa nthawi yomweyo ku gulu lina, koma
amasinthidwa kukhala mawu (Speech To Text) kenako mawu omveka kuchokera
wolembetsa A, yemwe:
- imatha kufalitsidwa ndi bandwidth yofunikira yocheperako (ngakhale kulumikizana ndi wailesi ya HF ndikotheka, ndi zina).
- ikhoza kusungidwa ndi algorithm iliyonse yamphamvu yachinsinsi
Kumbali B, mauthenga olandilidwa amasinthidwa ndikusinthidwanso ngati liwu lochokera
wolembetsa A (Mawu Opita Kulankhula).
Mukhozanso kukopera otchedwa B mbali. mawu avatar ya olembetsa A, amene angatero
kubwereza molondola njira yolankhulira olembetsa A.
Njira ina imatha kufalitsa phokoso lakumbuyo ndi malingaliro.
Zomwezo ndizowona pakulankhulana kwamakanema - makamaka popeza zinthu zamunthu zidakhalapo kalekale
kupezeka mumapulogalamu (masks osiyanasiyana, maziko mu Zoom, ndi zina).
Inde, pali mbali zaukadaulo zomwe pakadali pano sizinakwaniritsidwe m'njira yoyenera -
mwachitsanzo, kuthamanga kwa kutembenuka kwa Speech To Text kudzakhala kovuta, koma kugwiritsa ntchito
Ma aligorivimu a Predictive AI amatha kukulitsa liwiro ili.
Ubwino wofunikira kwambiri ndikuti bandwidth yaying'ono imafunikira pamayendedwe opatsira
deta.
Iwo. Mfundo imeneyi ingagwiritsidwe ntchito osati wamba tsiku ndi tsiku
mauthenga, komanso mauthenga ankhondo ndi akutali omwe akuchedwa kuchedwa
(kulumikizana mumlengalenga, interplanetary - Mwezi, Mars, etc. :)
Ngakhale izi ndizofotokozera za lingalirolo, kwenikweni, mu imodzi mwama projekiti athu pali kale angapo
Chitsanzo chokhala ndi mfundo imeneyi chakhala chikugwiritsidwa ntchito kwa miyezi ingapo.
Koma zambiri za izi nthawi ina ...
