DAYTAI MPEG2 MPEG4 HD 4-in-1 Encoder modulator,(DT-EM-4-MPEG2/MPEG4) are all-in-one devices which integrate encoding
(MPEG-2, MPEG-4/AVC H.264) and modulation to convert HDMI/YPbPr /CVBS (Pr in) signals etc to digital RF output.To meet customers'
various requirements,DT9542B is also equipped with 1 ASI input, and output with 2 ASI ports and 1 IP port. The signals source could be
from satellite receivers, closed-circuit television cameras, Blue-ray players, and antenna etc. Its output signals are to be received by TVs,
STB and etc with corresponding standard.DT-EM-4-MPEG2/MPEG4 series products are wildly used in public places such as metro, market
hall, theatre, hotels, restaurants and etc for advertising,monitoring, training and educating in company, schools, campuses, hospital… It's
a good choice to offer HD channels and more.
