24 Channels SD MPEG2 A/V input to DVB-T DVB-C QAM ATSC ISDBT RF Encoder Modulator
Περιγραφή
Summary
HPS724IV 4/8/12/16/20/24 Channels SD MPEG2 Encoder Modulator is a professional SD audio & video encoding, multiplexing and modulating device with powerful functionality. It support 4/8/12/16/20/24 CVBS input, MPEG2 encoding, 4/8 carriers of DVB-C/DVB-T/ATSC/ISDB-T RF output. This device can simultaneously encode 4/8/12/16/20/24 channel SD programs; moreover, it has IP (128 SPTS over UDP/RTP) input, 2 ASI input and can multiplex the input ASI/IP with the 24 encoded SPTS to generate a MPTS output. Επίσης, the PSI/SI information can be inserted into SPTS output. In conclusion, its high integrated and cost effective design makes the device widely used in varieties of digital distribution systems such as CATV digital head-end, satellite and terrestrial digital TV broadcasting, και τα λοιπά.
