Part Number: VIP472
Title: Video Line Insertion Processor
Category: A/V Baseband
Industry: TV/Radio Broadcast
The VIP472 is a line switcher that will insert any one video test signal line onto your NTSC video path so that you can monitor the trasmission signal quality. This process allows the video test signal to pass through all digital compression systems to verify that your video is being delivered accurately without distortion.
Most digital trasmission system will not pass the vertical interval. This system replaces the Vertical Interval Test Signals “VITS” and vertical Interval Reference Signals “VIRS” that were used to monior video quality, but are now lost due to digital compression.
This process momentarily inserts a video test signal onto a visual picture line at the top or bottom of th screen where it is least noticeable. The test signal is only on during the test and then turned off for normal video operation. You may select any line of video for test signal insertion by using a “dip” switch on the PC Card.
The unit has two BNC connector video inputs, one for the video and the other for the video test signal generator. A BNC connector “SYNC” output signal is provided to lock-up your test signal generator if needed. A secondary video output BNC connector is also provided on the main channel.
Line insertion is controlled by the front panel switch. This switch allows you to turn the insertion “ON/OFF” and select “REMOTE”. The “REMOTE” feature allows you to connect an external switch to the screw terminal connector, to control the insertion. There is a LED on the front panel to indicate video lock between main channel and the test signal generator. The unit also has a TTL output to indicate the video lock status remotely. In the event of a power failure the main video is by-passed to the primary output.
