HPS724IV 24 Channels A/V MPEG2 SD to RF Encoder Modulator

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. Also, 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, etc.
