What are the requirements for using PC output as a video source for our AVN422, AVN441 and AVN443 encoder models?
Using PCs as video sources has a few potential issues:
- They must produce a broadcast standard resolution and frequency.
480i@59.94Hz (720hX480v)
720p@50, 59.94 or 60Hz (1280hX720v)
1080i@50, 59.94 or 60Hz (1920hX1080v)
1080p@24, 50, 59.94 or 60Hz (1920hX1080v)
- To do embedded audio they must have audio clocks that meet jitter specifications. The audio clock must be synchronous to the video clock otherwise see item 3 below.
- If there are embedded audio issues (bad or garbled audio or encoding of video freezing after some time (from minutes to hours depending on specifics), try using analog audio input from the computer via separate cable to the RCA inputs or weidmueller in the case of AVN422.
