Product Description

Overview:

OTV-EM32 is a professional multi-channel encoder modulator, which integrates encoding, multiplexing and modulating functions in one standard 1U case. Supporting 1 encoding modulating module and 1 encoding module, and both modules accept analog CVBS inputs. After multiplexing the 16 encoded TS (17~32 channels) to the encoding modulating module through 1 ASI port and 1 IP port with one MPTS, and then generating 8 MPTS output through data port.

OTV-EM32 is a professional multi-channel encoder modulator also supports 1 DVB-C tuner input, 1 ASI and 256 IP input and 8 non-adjacent carriers output through RF output interface and data port output. The device is also characterized with high integrated level, high performance and low cost. This is very adaptable to newly generation DTV broadcasting system.
