Ibyemezo bya FCC HAC ibisabwa kugirango ugenzure amajwi

FCC isaba ko guhera ku ya 5 Ukuboza 2023, itumanaho rifite intoki rigomba kuba ryujuje ubuziranenge bwa ANSI C63.19-2019 (HAC 2019).
Ibipimo byongeweho ibisabwa byo kugenzura amajwi, kandi FCC yemeye icyifuzo cya ATIS cyo gusonerwa igice kubizamini byo kugenzura amajwi kugirango yemererwe gutunga intoki gutsinda icyemezo cya HAC mukureka igice cyikizamini cyo kugenzura amajwi.

Ikizamini cya tekiniki gisabwa kugirango uhindure inyungu y'ibiganiro, kugoreka, no gusubiza inshuro za KDB 285076 D04 kugenzura amajwi mugihe cyo gusonerwa DA 23-914

1.Hakurikijwe ubusonerwe, gusa CMRS Narrowband na CMRS Umuyoboro mugari wa majwi bisabwa kugira ngo byuzuze ibisabwa byo kugenzura amajwi ya TIA 5050-2018 Igenzura ry'amajwi:
1) Ikizamini cyo gukoresha imbaraga 2N
Kubizamini bikoresha imbaraga za 2N, serivisi zijwi hamwe na bande ikora kubikoresho byose byashyizwemo intoki hamwe nigenzura ryijwi ryumurongo umwe muto hamwe numuyoboro mugari wa codec mugace k’ikirere ukoresheje igipimo cya encoder cyatoranijwe nuwasabye agomba kuba afite byibuze inyungu imwe yamasomo≥ 6dB.
2) Ikizamini cyo gukoresha 8N imbaraga
Kubizamini bikoresha imbaraga za 8N, serivisi zijwi hamwe na bande ikora kubikoresho byose byashizwemo hamwe nigikoresho cyo kugenzura amajwi yumurongo umwe muto hamwe numuyoboro mugari wa codec mugace k’ikirere ukoresheje igipimo cya encoder cyatoranijwe nuwabisabye agomba kuba afite byibuze icyiciro kimwe yunguka≥ 6dB .. Ntibikenewe ko wuzuza cyangwa kurenza 18dB yuzuye yunguka ibisabwa bisabwa muri TIA 5050 Icyiciro 5.1.1.
2. Kubindi bikoresho byamajwi bidasuzumwa muri 2), kugoreka kwakirwa, imikorere y urusaku, hamwe ninshuro yakira amajwi muri TIA 5050-2018 nabyo ntibisabwa, ariko izi codec zamajwi zigomba gusuzuma inyungu zamasomo zirenze 6dB kuri 2N na 8N ivuga kuri serivisi zose zijwi, imirongo ikora hamwe nu kirere cyumuyaga wa terefone.

 

Ibindi bisabwa
1.Icyapa cyo gupakira kigomba kubahiriza ibisabwa na 47 CFR Igice cya 20.19 (f) (1) kandi bikerekana inyungu nyayo yamasomo yabonetse mugihe cyo gusonerwa codec cyemejwe muri 1) na 2) hejuru hamwe na 2N na 8N zikoreshwa.
2. Usibye ibisabwa byavuzwe muri 1) na 2) hejuru, serivisi zose zijwi, coDEC, imirongo ikora, hamwe nu kirere cyujuje ibyangombwa byo gusonerwa HAC bigomba kubahiriza 2019 ANSI Standard Igice cya 4 WD RF Kwivanga, Igice cya 6 WD T- Kwipimisha ibimenyetso.
3.Nyuma ya 5 Ukuboza 2023, imashini zikoresha intoki zigomba kwemezwa nubusonerwe cyangwa zujuje byuzuye igipimo cya ANSI 2019 na TIA 5050 Igenzura ryijwi. Igihe cyo gusiba kirangiye, niba nta kindi cyemezo cyafashwe na Komisiyo, imashini zikoreshwa mu ntoki zizafatwa nk'iyujuje ibyangombwa bisabwa kugira ngo zumvikane niba zujuje ubuziranenge bwa ANSI 2019 hamwe na TIA 5050 yo kugenzura amajwi.
4.Ibisabwa byo gusonerwa birangira nyuma yimyaka ibiri nyuma yitariki yatangarijweho itegeko ryo gusonerwa DA 23-914, kandi imashini zikoreshwa mu ntoki zabonetse muri iki kibazo zizasonerwa nkimfashanyo yo kumva.
5.Mu rwego rwo kwerekana ko byubahirizwa muri raporo yikizamini, itumanaho ryakoreshejwe rishobora kwifashisha uburyo bworoshye bwo gukora ikizamini ukurikije uburambe kugirango ugabanye umubare wibizamini.
Kubera ko atari codecs zose zishyigikiwe nigikoresho zigomba kuba zujuje ibisabwa, ntacyo bitwaye niba izo codecs zujuje ibisabwa cyangwa niba inyungu zamasomo zigomba gusuzumwa zidasonewe, raporo yikizamini igomba kuba irimo urutonde rwa codecs zose zishyigikiwe nigikoresho .
