5.4 Using the MLR to Receive Audio and Video
The MLR receives and demodulates COFDM radio signals from the microLite Transmitter. It
then decodes the MPEG4 transport stream for output.
The dual antenna diversity feature of the MLR is used to maximize the robustness of video
reception. The primary goal of dual antenna diversity is to enable the user to prevent line of site
obstruction on the transmission path from causing receiver errors to occur. By separating the
antennas, the user has two chances to receive the signal properly, regardless of obstructions
between the transmitter and MLR antennas. Properly directing your antenna to the transmit
source is key obtaining the best range possible.
Video may be viewed on a monitor, which accepts SD Composite video, or SDI. MPEG4
encoded video is also included in the transport stream on the ASI output, and must be decoded
using an MPEG4 decoder prior to viewing on a monitor.
Audio can be output to a recorder or amplifier. Audio is also embedded in SDI outputs, and
included in the transport stream on the ASI output.
Streaming video and audio can be output via a laptop or PC with a compatible MPEG4 decoder
program.
5.5 Verify Operation
After installing the MLR, turn on the power to the receiver and your overall system. The LED's
