THEORY OF OPERATION
Maximal-Ratio Combining Circuit
This feature enhances the robustness of the receiver when line of site obstructions occur in the transmission path.
MPEG4 and MPEG 2 Decoder
The AB-HDRX contains a built-in auto-detect MPEG4 (H.264 part 10) compliant and MPEG2 decoder. The decoder audio and video output is
available on the SDI output jack. Both HD-SDI and SD-SDI are output on the SDI jack.
Video Outputs
Video output jacks include:
ASI – Encoded transport stream
SDI – HD-SDI and SD-SDI audio and video
Composite Video – The AB-HDRX composite video output circuit automatically outputs any SD video into either NTSC or PAL.
Audio Outputs
The AB-HDRX has left and right audio line output jacks. Stereo audio is also part of the ASI and SDI video outputs. The Audio output jacks are
RCA connectors.
User Data Output
A data channel is transmitted with the audio and video information. Access of the data channel is through the RS-232 serial interface output
connector. The baud rate and other RS-232 parameters are programmable.
Video over IP Encapsulation for Streaming Video
The AB-HDRX features a 100 Mbps Ethernet LAN interface for streaming video over IP. This feature allows received video to be viewed
remotely using MPEG4 decoder software on a personal computer.
Local User Interface
If you commonly use several configurations in the field, the faceplate LED preset settings and “Set” selector button provide a quick way to
change pre-programmed configurations. Status information is also presented by LED’s. Refer to page 9 for more information.
Remote Control and Firmware
Remote Control via Ethernet
An Ethernet port allows remote control of all configuration options, as well as monitoring of internal status and settings.
The AB Control Software is available for controlling the unit via the Ethernet port. Any Windows compatible computer running Windows XP or
Windows 7 with 500 MB of memory and 1 GHz Pentium or above can be used. Refer to the AB Control Software Manual for more information.
Remote Control via RS-232
An RS-232 command set is implemented to allow remote control of all configuration options, as well as monitoring of internal status and
settings. Commands and responses are sent via the RS-232 serial interface on the 9-pin connector.
The AB Control Software is available for controlling the unit via the RS-232 serial interface. Any Windows compatible computer running
Windows XP or Windows 7 with 500 MB of memory and 1 GHz Pentium or above can be used. Refer to the AB Control Software Manual for
more information.
Firmware updates
