Description
The R. L. Drake model MQM1000 is a professional quality, digital headend transcoder that accepts one or two MPEG2 digital inputs via two Asynchronous Serial Input (ASI) connectors. These signals must be ATSC compatible streams if multiplexing is to be performed and usually will have originated from a local TV broadcast station and may have been transported over fiber links to the MQM1000. After multiplexing and null packet management, the MQM1000 QAM modulates and up converts onto any desired CATV or off-air output channel between 54 and 1002 MHz. The MQM1000 can also operate as a non-multiplexing QAM modulator when a single ASI input is selected.
