| Analog wireless camera systems have been available to the broadcast industry for
decades and are in common use at sporting events for sideline coverage of
football, pit-lane coverage of car racing, etcetera.
Analog systems are
essentially line-of-sight systems, meaning that the frequency modulation (FM )
used requires an uninterrupted path between the transmitter and receiver.
In
situations such as transmission in built-up areas where the transmitted signal
can be reflected by a number of routes back to the receiver (multipath
interference), analog systems can suffer from picture-quality impairments such
as ghosting, noise, chroma flutter, or complete loss.
Viewers have become used
to these impairments, which can occur when watching in-car cameras or marathon
coverage, typically when the transmitter passes under a bridge or behind an
obstacle. Traditional analog systems, therefore, have never offered true roaming
freedom to cameramen.
Analog wireless cameras need labor-intensive manual
targeting of transmit and receive antennas to ensure a reasonable quality of
link.
