DTT issue

Post by stevense23 » Tue Oct 21, 2014 9:27 pm

Hello, is there someone here who knows about ISDBT system? We are currently have a test broadcast issue. We provided a DTT head end to our client. Transmitter side is a different contractor. During integration and fire up of the transmitter an issue arose when the channels on the stb can't be viewed properly. It seems the video and audio is not decoded properly. During the testing on our side via our exciter, it is ok but when it is connected to their exciter, thats when the issue arose. The encoder and mux is on the studio and it is connected via microwave link to the transmitter. Do you know what is causing the problem? Our guess is that there is some jitter occurring in the microwave link. Do you have some recommendations to solve this? Thanks in advance.
