Got this from WXIX Chief Engineer. The audio is low because we were attempting to deal with a problem we were having with Fox HD audio levels during dramatic programming. Example – “House”. Since normally when we splice the Fox HD transport stream into our encoder we have no handle on audio levels (or video levels) since their transport stream is spliced directly into our digital encoder which is the last piece of equipment in line before the transmitter. We were trying to compensate for the extreme difference in audio levels when we would cut to our local interstitials from Fox HD (which would knock you off your chair). We tried experimenting with lowering our overall level to more closely match Fox to avoid the huge difference in levels. However, it seems that recently Fox has taken note of our many complaints regarding low audio levels on their dramatic programming as just recently their levels have come up closer to normal. The reason the audio level is lower when we run the ticker is because we are now decoding the Fox HD signal so we can run it through our ticker. And when it runs through our ticker it also is processed through our audio path which has been lowered due to the reasons I just explained above. We will raise our overall levels back to normal, probably by Monday. Now for further explanation, as you may be wondering why we are now able to decode Fox HD and run the ticker over Fox in HD when in the past we had to resort to an up-converted SD Fox signal in 4x3 with the dreaded black “wings” to get the ticker on. We have installed a transport stream decoder for Fox HD so that we can now run a ticker and weather alerts over Fox in HD. Which do you think derogates the HD signal more, going to up-converted SD in 4x3 with the black wings or decoding the transport stream and staying in 16x9 HD? We may possibly be the only Fox affiliate in the country that is running a ticker and alerts over Fox in HD. Hope this clarifies to anyone experiencing the issue. |
