[QUOTE="LateAdopter, post: 1082305, member: 412234"] 25 frames per second progressive scan. Broadcast TV is normally 25fps interlaced, with the fields captured at different times, called 25i by EBU or 50i by ITU, originally to reduce the required bandwidth. Deinterlacing properly produces 50fps progressive scan output. But films are shot at 24fps and broadcast at 25fps so the fields were captured at the same time. Also consumer and outside broadcast cameras commonly produce 25p output, so there is no benefit from interlacing. When the BBC started switching between 25i and 25p it caused problems with some TVs, notably Sony, but they were fixed by a firmware update. I don't know whether this is what France TV has been doing. [/QUOTE]
