He nui ka poʻe e hoʻomanaʻo i ka moʻolelo TV "Silicon Valley" e pili ana i ka mea programmer Richard
ʻO Hendrix, ka mea i hōʻea mai me kahi algorithm compression data revolutionary a hoʻoholo
kūkulu i kāu hoʻomaka.
Ua ʻōlelo pū nā mea kūkākūkā o ka moʻo i kahi metric e loiloi ai
ʻO nā algorithms like ka Weissman Score fictitious.
Ma kahi o ka moʻolelo, ua hana ka mea hoʻomaka i kahi kamaʻilio wikiō me ka hoʻohana ʻana i kēia hopena.
Kāhea ʻia ke kaiāulu i mahalo ʻia e kūkākūkā i kahi ʻē aʻe
ke kumu o ka hoʻopili ʻana i ka ʻikepili no nā kelepona leo a me nā wikiō, e hoʻonā i ka pilikia me kahi mea hou,
ʻaoʻao i manaʻo ʻole ʻia.
Inā makemake ʻoe e komo i ke kūkākūkā o kēia hoʻonā, a e ʻike pū i ke ʻano o kēia
nā manaʻo me Jonathan Swift a me nā hana a Leo Tolstoy, e ʻoluʻolu ma lalo o ka pōpoki.
Keʻano o ka manaʻo
E wehewehe mākou ma nā ʻōlelo maʻamau i ka hana ʻana o ke kamaʻilio leo o kēia wā - ua like ke kumu no nā mea ʻelua
kelepona ma luna o ka pūnaewele GSM, a me nā ʻelele koke a me nā pūnaewele VOIP.
Hoʻouna ʻia nā haʻalulu kani i ka microphone o ke kelepona, a laila ma ka analog-digital
mea hoʻololi (ADC a i ʻole ADC):
A laila, hoʻopili ʻia me nā codecs like ʻole (G711, G729, OPUS, GSM, etc.),
hoʻopili ʻia ka hoʻopunipuni a ʻaʻole hoʻohui ʻia (SRTP, ZPTP, etc.) a hoʻouna ʻia i ke kaiapuni
lawe ʻikepili.
No ka laʻana, kokoke i nā ʻelele koke (WhatsApp, Viber, etc.) hoʻohana i nā codecs like (i kēia mau lā ʻo Opus kēia), a aneane like iki.
nā protocol i hoʻololi ʻia (ma muli o SIP, WebRTC).
ʻO ka pūnaewele hoʻoili ʻikepili hiki ke lilo i ka pūnaewele lehulehu a i ʻole ka pūnaewele GSM a i ʻole
intranet:
ʻO ka hoʻopili ʻana he mea koho i kēia papahana, no ka laʻana ma ka hapa nui o nā hihia no
ʻAʻole hoʻohana ʻia ka hoʻopili kelepona SIP.
Akā i nā ʻelele, ʻokoʻa, hoʻohana pinepine lākou i kā lākou ponoʻī
nā protocols no ka hoʻopili leo a me ka wikiō.
A laila, ke kaʻina hana hoʻohuli - ka mea loaʻa, i ka loaʻa ʻana o ka ʻikepili, hoʻokaʻawale i ka ʻike i loaʻa, a laila hele ka hōʻailona i ka DAC (digital-to-analog converter) a laila komo i ka amplifier leo i pili i ka mea haʻi'ōlelo.
Nā hiʻohiʻona o nā codec hou:
G.711 64 Kbps.
G.726 16, 24, 32 a i ʻole 40 Kbps.
G.729A 8 Kb/sec.
GSM 13 Kb/sec.
iLBC 13.3 Kb/sec. (30ms kiʻi); 15.2 Kb/sec. (20ms kiʻi)
Māhele Speex mai 2.15 a i 22.4 Kb/sec.
G.722 64 Kbps.
No laila, no ka laʻana, i loko o kahi kamaʻilio 7 mau minuke ma WhatsApp a i ʻole Skype
Ma kahi o 1 MB i hoʻohana ʻia.
E hoʻomanaʻo kākou i kēia mau helu - 1MB no 7 mau minuke o ke kamaʻilio ʻana, pono koke mākou.
"Ua like ʻo Leo Tolstoy me ke aniani ... o ke kipi ..."
E hoomanao kakou i ka moolelo kaulana loa o keia mea kakau Rusia nui.
ʻO "War and Peace" kahi moʻolelo epic na Leo Nikolaevich Tolstoy, e wehewehe ana i ka Lūkini
ka hui i ka wā o nā kaua kūʻē iā Napoleona i ka makahiki 1805-1812. ʻO ka epilogue o ka moʻolelo e lawe mai
moʻolelo a hiki i 1820.
ʻO ka moʻolelo "War and Peace" na L.N. Ua hoʻolaʻa ʻo Tolstoy i ʻehiku mau makahiki o ka hana ikaika a hoʻomau i ka hana ʻana o kekahi o nā mea nui loa o ka honua.
"Ke Kaua a me ka Maluhia": aia ka waihona o ka mea kākau ma luna o 5200 mau pepa i kākau maikaʻi ʻia.
Inā makemake ʻoe e heluhelu i kēia puke, hiki iā ʻoe ke hoʻoiho maʻalahi.
A ʻo kēia faila wale nō ke kaumaha... 1 MB:
ʻO nā format fb2 a me epub, e like me zip, rar, ma ke kumu, hiki ke noʻonoʻo ʻia he ʻano
codecs
E noʻonoʻo kākou - 7 mau minuke o kā mākou kamaʻilio ʻana ma WhatsApp e like me ka nui o ke kaʻa
he hana nui i 7 makahiki e kakau ai!
Ua hoʻopili ʻia kahi kamaʻilio ʻana o 7 mau minuke me ka codec opus, ua hoʻopili ʻia ka puke me ka ePub, ua like ka leo -
1MB, akā he ʻokoʻa nui loa!
Ka huakai a Gulliver
Ua ʻike nā kānaka a pau i kēia hana a Jonathan Swift mai ka wā kamaliʻi, akā ʻoiaʻiʻo, ʻaʻole no kēia puke
keiki.
ʻO Gulliver's Travels he mea hoʻomāʻewaʻewa politika no ka poʻe mākua, ʻoiaʻiʻo nō ma ka pōʻaiapili o 18
kenekulia.
ʻO ka mea kupanaha, ʻo Swift, he hoa paio ikaika ʻo ia o kāna mau hoa hou -
ʻO Newton, ma kāna "Gulliver's Travels" ʻaʻole i wānana wale i ka loaʻa ʻana o nā satelite
ʻO Mars (me ka wehewehe pololei o kā lākou mau hiʻohiʻona), akā ua wehewehe pū kekahi i kahi mea hoihoi
ke ala o ke kamaʻilio ʻana ma waena o nā kānaka:
“... ua koi ka papahana e hoʻopau loa i nā huaʻōlelo a pau;
ʻO ka mea kākau o kēia papahana i kuhikuhi nui i kāna mau pono olakino a me ka mālama kālā
manawa
Ma hope o nā mea a pau, ua maopopo ka pili ʻana o kēlā me kēia huaʻōlelo a mākou e haʻi aku ai me kekahi mau lole a me nā waimaka.
nā māmā a, no laila, ke alakaʻi nei i ka emi ʻana o ko mākou ola.
A no ka mea he mau inoa wale nō nā huaʻōlelo, manaʻo ka mea kākau o ka papahana
e oi aku ka pono ia makou ke lawe pu i na mea e pono ai ke hoike aku i ko makou
nā manaʻo a me nā makemake.
... nui ka poʻe naʻauao a naʻauao i hoʻohana i kēia ala hou o ka hōʻike ʻana i kā lākou
nā manaʻo me ke kōkua o nā mea.
ʻO kona pilikia wale nō, inā pono,
e alakaʻi i kahi kamaʻilio lōʻihi e pili ana i nā kumuhana like ʻole, pono e lawe nā interlocutors
nā poʻohiwi me nā pūʻolo nui o nā mea, inā ʻaʻole ʻae ke kālā e hoʻolimalima i hoʻokahi a i ʻole
ʻelua kāne kiʻekiʻe. Ua ʻike pinepine au i ʻelua mau kānaka naʻauao, luhi ma lalo
kaumaha kaumaha, e like me ko makou poe kalepa. I ko lāua hui ʻana ma ke alanui, ua kiʻi lāua
ʻeke poʻohiwi, wehe aʻela a lawe i nā mea e pono ai mai laila mai, a pēlā i kamaʻilio ai
hoomau o ka hora; a laila, hōʻuluʻulu lākou i kā lākou mau ipu a kōkua kekahi i kekahi e hāpai i ka ukana ma luna
poʻohiwi, ʻōlelo aloha a kaʻawale.
Eia naʻe, no nā kamaʻilio pōkole a maʻalahi hiki iā ʻoe ke lawe i nā mea āpau āu e pono ai i loko o kāu ʻeke
a i ʻole ma lalo o ka lima, a ʻo ke kamaʻilio ʻana ma ka home ʻaʻole ia he kumu
pilikia. No laila, piha nā lumi kahi e ʻākoakoa ai ka poʻe e hoʻohana nei i kēia ʻano hana
nā ʻano mea a pau i kūpono e lilo i mea no ia mea hana
kamaʻilio.
ʻO kekahi mea maikaʻi ʻē aʻe o kēia ʻano mea hiki ke hoʻohana ʻia
ma ke ʻano he ʻōlelo holoʻokoʻa, hiki ke hoʻomaopopo ʻia e nā lāhui kanaka āpau, no nā lako a me nā hale
ua like a like loa na ipu ma na wahi a pau, i hiki ke hoomaopopo pono ia lakou.
No laila, hiki i nā ʻelele ke kamaʻilio maʻalahi me nā aliʻi ʻē a i ʻole
nā kuhina nona ka ʻōlelo i ʻike ʻole ʻia e lākou..."
No laila, manaʻo paha ʻoe i hea wau e hele ai me kēia :)
No ke aha e hoʻouna ai i nā haʻalulu ea (leo) ma luna o nā haneli a me nā kaukani kilomika?
hoʻopilikia i ka hoʻopili ʻana (no ka haʻi ʻana i kēia mau haʻalulu o ka ea i ka mea e loaʻa me ka pololei a me ka maikaʻi e like me ka hiki), mālama i ka bandwidth pono, inā semantic
He liʻiliʻi paha ka haʻawe o kēia hoʻouna ʻana, a i ʻole i ka ʻole?
Ma hope o nā mea a pau, kamaʻilio ka poʻe me kekahi i kekahi ʻaʻole me nā leo, akā me ka manaʻo, ʻike, semantics, manaʻo ...
He maʻalahi ka manaʻo o ka ʻōnaehana kamaʻilio hou - ma ka ʻaoʻao kumu A aia nā leo
ua hoʻoheluhelu ʻia nā haʻalulu, akā ʻaʻole i hoʻouna koke ʻia i kekahi ʻaoʻao, akā
ua hoʻololi ʻia i kikokikona (Speech To Text) a laila ka kikokikona koʻikoʻi mai
ka mea kākau inoa ʻo A, nāna:
- hiki ke hoʻouna ʻia me ka bandwidth data liʻiliʻi e koi ʻia (ʻoiai hiki ke kamaʻilio lekiō HF, etc.)
- hiki ke hoʻopili ʻia me kekahi algorithm encryption ikaika
Ma ka ʻaoʻao B, hoʻokaʻawale ʻia nā memo i loaʻa a hoʻopuka hou ʻia ma ke ʻano he leo mai
mea kākau inoa A (Text To Speech).
Hiki iā ʻoe ke hoʻoiho i ka ʻaoʻao i kapa ʻia ʻo B. leo avatar o ka mea kākau inoa A, ʻo wai ka mea makemake
Ua ʻōlelo hou ʻo ia i ke ʻano o ka ʻōlelo a ka mea kākau inoa ʻo A.
Hiki i kahi kaila kaawale ke hoʻouna i ka walaʻau a me nā manaʻo.
He ʻoiaʻiʻo nō nā mea a pau no ke kamaʻilio wikiō - ʻoiai ʻoiai ua lōʻihi nā mea hoʻokahi
Aia i loko o nā noi (nā masks like ʻole, ka hope ma Zoom, a me nā mea ʻē aʻe).
ʻAe, aia nā ʻano ʻenehana i kēia manawa ʻaʻole i hoʻokō piha ʻia i ke ʻano kūpono -
no ka laʻana, e koʻikoʻi ka wikiwiki o ka hoʻololi ʻana i ka ʻōlelo i ka kikokikona, akā hoʻohana
Hiki i nā algorithm hoʻololi wānana AI ke hoʻonui nui i kēia wikiwiki.
ʻO ka pōmaikaʻi koʻikoʻi ʻo ia ka liʻiliʻi o ka bandwidth i koi ʻia i ka medium transmission
ʻikepili.
ʻO kēlā mau mea. Hiki ke hoʻohana ʻia kēia kumukānāwai no nā lā maʻamau
kamaʻilio, akā no ka pūʻali koa a me nā kamaʻilio lōʻihi me nā lohi lōʻihi
(Ke kamaʻilio lewa, waena honua - Moon, Mars, etc. :)
ʻOiai he wehewehe kēia o ka manaʻo, ʻoiaʻiʻo, i loko o kekahi o kā mākou papahana aia kekahi
Ua hoʻohana ʻia kahi prototype me kēia kumu no nā mahina.
Akā hou aʻe e pili ana i kēlā manawa aʻe ...
