ZJ3308AT 8 ho 1 ATSC Modulator
Kakaretso ea Sehlahisoa
ZJ3308AT 8 ho 1 ATSC modulator ke sehlahisoa se sa tsoa qaptjoa se tšehetsang tlhahiso ea IP. E na le liteishene tse 8 tsa multiplexing le liteishene tse 8 tsa ho feto-fetoha ha ATSC, 'me e ts'ehetsa ho kenya palo e hodimo ea 256 IP ka boema-kepe ba GE. ZJ3308AT e na le matla a mangata a hlahisoang ke bajari ba 8 ba seng haufi (50MHz ~ 960MHz) ba hlahisang sebopeho sa RF. Sistimi ea sesebelisoa sena e ka laoloa moleng le ho ntlafatsoa ka marang-rang, e ka sebelisoang haholo ho setupong sa marang-rang sa phatlalatso ea dijithale tsa ATSC le ho etsa liteko tsa moralo oa lebokose la top ATSC.
Likarolo tsa bohlokoa
● Likou tse 3 tsa GE (max 256 IP in):
● Libaka tsa data1 & Data2 tse habeli, mahlakore a maholo a 256 IP ho, 8 IP out port port (e fumanehang kapele), max IP IP ho
● Max 840Mbps bakeng sa kenyelletso ka ngoe
● E tšehetsa phetoho e nepahetseng ea PCR
● E tšehetsa phetoho ea PID le ho hlophisa PSI / SI
● E ts'ehetsa ho khutlisa li-PID tse 180 ho ea ka mocha
● Tšehetsa 8 multiplexed TS ka UDP / RTP / RTSP
● Lihlahisoa tse 8 tsa ATSC tse seng haufi, tse lumellanang le maemo a ATSC A / 53
● E tšehetsa kh'outo ea RS (208,188)
● Ts'ehetsa taolo ea marang-rang e thehiloeng marang-rang
