It occurred to me in the middle of the night that you MIGHT mean this, however the Ch3/4 RF output putting out an analog AM video signal with a separate FM analog audio signal, and what your OTA digital box is looking for is an FM digital signal containing both audio and video. Plus, I don't think that most SD DVB boxes are putting anything out when on a
HD channel. I think that all my boxes do is give a blue screen. I'm not sure, but I think this is because the hardware just isn't capable of dealing with
HD, so there just isn't any signal there to be modulated on the RF output anyway. But regardless, I really don't think that there is any chance that this would work.

I don't have enough knowledge to say for sure that this is or isn't possible, but I really think that if this were possible that one of the DVB boxes would already be doing it. My suspicion is that this is more than a software problem, ie that the video decoding is done by a hardware chip set which can't handle
HD, and even if it is capable of doing
HD, I think that the hardware after the decoding chip isn't going to be happy with
HD, since it's all aimed at SD PAL or NTSC. I really think this just isn't going to work, but even if it COULD work, I don't see ANY motivation for the manufacturer of a DVB box to do the extensive software upgrade necessary to do this, when they are more interested in getting you to buy new models. If it were as simple as you suggest, they would have added an
HD output in the first place and charged a bit more for the box. I think there is a reason why
HD receivers cost more, and I think it comes down to the choices they have made for chips that do hardware decoding and licensing for codecs, etc.
But that's just my opinion which isn't based on any hard knowledge of the chips involved, so I may well be wrong.
