The extent to which the data is available is the name field in the G_FMT call: http://linuxtv.org/downloads/v4l-dvb-apis/vidioc-enuminput.html For most devices, the driver developer names the individual inputs "Composite", "S-Video", "Tuner", etc. The only level of distinction other than the name is the type field, which today is V4L2_INPUT_TYPE_TUNER for an RF tuner and V4L2_INPUT_TYPE_CAMERA for everything else. To my knowledge there aren't any current drivers in the main tree that support DVI or SDI capture, so nobody has really cared to make the API more flexible to extend the "type" field with other values (which would both be easier to machine parse, localize, and be consistent across boards).
