QUICK SET-UP
Figure 1: AB-HDRX Antenna Connectors
The AB-HDRX has a wide range of programmable settings. Before using the AB-HDRX in your application, you should pre-configure it to for
the settings you want to use in your application. Settings are selected and configured using the AB Control Software. Please refer to the AB
Control Software Manual for details.
Using the AB-HDRX to Receive Audio and Video
The AB-HDRX receives and demodulates COFDM radio signals from the AB-HDTX. It then decodes the MPEG4 transport stream for output.
The dual antenna diversity feature of the AB-HDRX 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 AB-HDRX
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. 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 may be output via a laptop or PC with a compatible MPEG4 decoder program.
Verify Operation
After installing the AB-HDRX, power up the receiver by attaching a Logic Series battery and your overall system. The LED’s on presets 1-4 will
sequentially illuminate until boot up is complete.
Verify operation of the AB-HDRX by using the following methods:
•
Use a video monitor to view SD Composite video (NTSC or PAL, as appropriate).
•
Display video on equipment with ASI or SDI input connectors. This may include video analysis equipment or PC’s with ASI or SDI input
cards used for video storage and editing.
•
To stream video over IP use the Ethernet connection to a PC or laptop running a compatible MPEG4 audio and video decoder program.
Streaming Video over IP/Ethernet
The AB-HDRX is pre-configured to stream video over IP on its Ethernet port. To stream video over IP use the Ethernet connection to a PC or
laptop running a compatible MPEG4 audio and video decoder program.
