Okudawunilodiwe

Ukuqondiswa komzali

Mayelana nalolu hlelo lokusebenza

I-Assempix ihlukanisa amasiginali womsindo afakwe ikhodi ye-COFDMTV ezithombeni futhi isekelwe kusofthiwe yomthombo ovulekile.

I-COFDMTV isekelwe kubuchwepheshe be-COFDM (coded orthogonal frequency-division multiplexing):
- 160 ms ubude bezimpawu ze-OFDM
- 6.25 Hz inkampani yenethiwekhi ngayinye
- 1/8 isikhawu sonogada
- ukushintshwa kwe-PSK okufakwe ngokuhlukile (i-phase-shift keying).
- amakhodi e-polar ahlelekile okulungisa iphutha langaphambili

Amamodi alandelayo asekelwa:

Ukusebenzisa i-SPC(64800, 43072):
Imodi 6: 8PSK, 2700 Hz BW futhi cishe amasekhondi angu-10 ubude
Imodi 7: 8PSK, 2500 Hz BW futhi cishe amasekhondi angu-11 ubude
Imodi 8: QPSK, 2500 Hz BW futhi cishe imizuzwana engu-16 ubude
Imodi 9: QPSK, 2250 Hz BW futhi cishe amasekhondi angu-18 ubude

Ukusebenzisa i-SPC(64512, 43072):
Imodi 10: 8PSK, 3200 Hz BW futhi cishe amasekhondi angu-9 ubude
Imodi 11: 8PSK, 2400 Hz BW futhi cishe imizuzwana engu-11 ubude
Imodi 12: QPSK, 2400 Hz BW futhi cishe imizuzwana engu-16 ubude
Imodi 13: QPSK, 1600 Hz BW futhi cishe amasekhondi angu-24 ubude

Ukulayisha kufanele kube kuncane noma kulingane namabhayithi angu-5380.
Amafomethi ezithombe ze-JPEG, i-PNG ne-WebP asekelwa.
Ububanzi nobude bukhawulelwe phakathi kwamaphikseli angu-16 no-1024.

Ukuphepha kwedatha

Ukuphepha kuqala ngokuqonda ukuthi onjiniyela baqoqa futhi babelane kanjani ngedatha yakho. Ubumfihlo bedatha nezinqubo zokuphepha zingahluka kuye ngokusebenzisa kwakho, isifunda, nobudala. Unjiniyela unikeze lolu lwazi futhi angalubuyekeza ngokuhamba kwesikhathi.
