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.
Features:
- Front panel display and buttons allow easy setup and monitoring of operating mode and parameters
- High output, 61 dBmV, QAM modulator and very low phase noise agile upconverter are built in
- Output is agile on CATV or broadcast channels from 54 to 1002 MHz - Dual ASI Inputs
- TS Multiplexer for MPEG2 streams
- Program filtering of both A and B input streams. User may select or drop any of the incoming programs
- ATSC PSIP is supported
- MPEG program and minor channel number offsetting when multiplexing
- Major channel number pass through or remarking is selectable when multiplexing
- Rewriting of the MPEG tables is provided when two input streams are multiplexed
- PCR correction is performed when necessary
- RS232 remote control and monitoring capability with the included Drake Digital Headend Control Software (v. 2.6 or later)
- High MER output signal quality
- 1U tall package with internal power supply conserves rack space
- Manufactured in the USA
