Thanks to all of the great information and advice from AVS forum members, a successful solution to this problem has been found. Since my friend that had the problem as described in my original posting lives in Texas and I live in Tennessee, it took some time time in communicating and discussing what we had learned on the forum in order to come up with a "workable" solution. In the end, it occurred to me that, rather than purchase a device specifically designed to decode only the audio content of the digital broadcast signal, a less expensive solution was available. From earlier "testing", we had found that the analog stereo audio output from his DVD player, when connected to the TV's analog stereo input and then out via the TV's digital optical ouput to a "optical to analog stereo audio converter" and then out to the headphone base, would pass the audio through. Given this, it seemed reasonable that, rather than purchase an special digital audio decoder, a digital to analog signal converter such as had been purchased and used by many of us during the transition from analog to digital TV broadcast, should also work. Since I no longer needed any of the converters which I had purchased during that transition, I sent him one of my "leftovers". He put a "splitter" in his antenna "feed", running one output of the "splitter" to his TV and the other to the digital to analog converter. The composite video and analog stereo audio outputs of the converter were then connected to the corresponding inputs of the TV where the DVD player had previously been connected. The DVD player was then connected to the TV's component video/analog stereo audio input. With this "lash up", he simply uses the "remotes" for his TV and/or converter to configure the TV's input and the converter channel selection. He says that, surprisingly, the TV video quality difference between that coming from the converter and that of the direct digital HD broadcast is barely noticeable, if at all. Most of all, his original problem with using his old wireless headphones has been solved.
