Product Overview
Voca encoder modulator is Vocas a all-in-one device integrating MPEG2 encoding and modulating to convert audio/video signals into ATSC RF out. It support 4 HDMI inputs optional, and its pay-as-you-grow modular design (maximum support 8 HDMI inputs) and flexible configuration are making it extremely scalable, very reliable with high performance. The signals source could be from STB, satellite receiver, closed-circuit television cameras and antenna etc. Its output signal is to be received by TVs or STBs etc.
