Muchikamu chino tichaziva kuti chii chinonzi IPTV maficha uye mabhenefiti ayo.
IPTV inodyidzana network terevhizheni, inova tekinoroji-nyowani inoshandisa Broadband cable TV network uye inobatanidza matekinoroji akasiyana seInternet, multimedia, uye kutaurirana kupa vashandisi vepamba akasiyana masevhisi anodyidzana, kusanganisira digital TV.Vashandisi vanogona kunakidzwa neIPTV masevhisi kumba.IPTV haina kungosiyana neyechinyakare analog tambo TV, asi zvakare yakasiyana neyekare dhijitari TV, nekuti ese ari maviri echinyakare analog TV uye yemhando yepamusoro dhijitari TV ine hunhu hwekuparadzanisa frequency, nguva, uye nzira imwe chete kutepfenyura.Kunyangwe yekirasi yedhijitari TV ine akawanda ehunyanzvi tekinoroji akaenzaniswa neanalog TV, ingori shanduko yechimiro chechiratidzo, kwete nzira iyo midhiya inofambiswa nayo.
Yayo sisitimu magadzirirwo anonyanya kusanganisira ma subsystems akadai sekushambadzira midhiya sevhisi, chirongwa editing, kuchengetedza, chokwadi uye kubhadharisa, etc. Iyo huru yemukati yakachengetwa uye inotumirwa ndeyekutepfenyura midhiya mafaera neMPEG-2/4 chiyero seiyo encoding core, yakavakirwa paIP network. kutapurirana, kazhinji kunoda Gadzirisa zvemukati sevhisi sevhisi node, gadzirisa kutenderera midhiya masevhisi uye ekuchengetedza zvishandiso, uye mushandisi terminal inogona kunge iri IP set-yepamusoro bhokisi + TV, kana PC.IPTV inogona kushandisa zvivakwa zvetambo terevhizheni network, kushandisa TV yekumba sechinhu chikuru chekupedzisira, uye inopa akasiyana siyana edhijitari midhiya masevhisi anosanganisira zvirongwa zveTV kuburikidza neInternet protocol.
Iwo makuru maficha eIPTV anoratidzwa mune zvinotevera zvinhu zvina:
(1) Kutakura paIP network, inogona kupa vashandisi nemhando yepamusoro yedhijitari midhiya ruzivo masevhisi;
