There is some diversity support hidden in the dib8000-driver and in some board-drivers which use it. Basically it creates several instances of the dib8000-driver (one for each demod) but it exposes only one dvb-frontend to userspace via the API. When the user is tuning the frontend he is, in fact, tuning all of them in diversity. IMO, the question which needs to be discussed is for diversity-support is an "how to change the API"-question and how does userspace can control it? In my experience with multi-frontend-hardware, which can do diversity or dual/triple-reception or both at the same time, is that the question is the routing and the grouping of frontend and assigning them to their sinks (stream-interfaces). Right now DVB-API can expose several frontends and dvrs and demuxes for one device, but there is no way to userspace telling the hardware to combine frontend0 and frontend1 to do diversity. When looking at diversity/multi-frontend problems, IMHO, we should not limit ourselves to USB-devices. The real usage of those MFE-devices is in an embedded hardware (STB in a car or at home). -- Patrick -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
