Methods, systems, and apparatus can provide channel scanning. In various examples, a channel scanning module can instruct scanning of multiple channels within a wideband frequency range by assigning channels to one or more demodulators to attempt to lock onto a signal at the assigned channel. In other examples, a channel scanning module can instruct scanning for downstream channels by assigning channels to multiple narrowband tuners and multiple demodulators to attempt to lock onto a signal on the assigned channel.
