VIDEO AND AUDIO DECODING	RECORD TRANSPORT STREAM
-The DTV Investigator decodes all 18 ATSC formats and displays on the LCD screen, with on-screen closed caption. In the case of multi-program Transport Stream, the user can select which program to monitor -The DTV Investigator monitors audio channels activities and provides AC-3 output as well as decoded analog audio	-Trigger a recording of a Transport Stream -Playback recorded file for analysis
VSB MONITORING	TRANSPORT MONITORING
The DTV Investigator can tune any UHF/VHF channel and monitor all the 8VSB parameters needed to qualify the RF reception. It provides alarms, logging and display of Level, MER, EVM, Constellation, Eye diagram and much more.	The DTV Investigator monitors and logs Transport Stream errors including PCR, Sync, and continuity error. The Transport Stream can either be demodulated from the 8VSB input for off air monitoring or input directly into the SMPTE310M input. This monitoring allows quick detection of Transport Stream errors insuring quick troubleshooting and assurance that your broadcast signal meets specifications.
BITRATE MONITORING The DTV Investigator monitors the bitrate of each PID present in the stream. A graphic representation makes it easy to see if video or audio are present and at the correct bitrate. The DTV Investigator also provides a bitrate histogram of a selected PID for long term monitoring. This feature provides useful information on the bitrate variations that can be used for opportunistic data insertion.	VIDEO AND AUDIO MONITORING The DTV Investigator monitors video and audio in real time through an internal decoder. The video is displayed and each audio channel (Up to 6 channels) is monitored with a graph on the integrated display. The DTV Investigator also provides a down converted NTSC output, as well as a decoded stereo audio and optical AC-3 output. The AC-3 output can be connected to a standard receiver for 5.1 audio monitoring. This feature provides you with confidence that your signal is on the air and allows transport stream errors to be tied to the video/audio.
