View of the device
DM-313 R81712 makes a part of MMH-3000 headend, cooperating with RDC-313 receiver. It decompresses a desired program from MPEG-2 transport stream. If the RDC-313 receiver incorporates CA module, the transport stream is usually unencrypted.
Notice! One module receives one program.
The device has been also equipped with VSB modulator (PAL). Thanks to vestigial side band the modulator allows to utilize adjacent channels. This kind of operation requires balanced output levels of output channels. The differences among individual channels cannot exceed 3 dB.
