According to https://www.digitalbroadcasting.com/doc/broadcom-ghz-full-band-capture-multi-channel-receivers-0001 :
Broadcom’s innovative wake-on transport technology allows the main SOC to be placed into deep sleep mode while the BCM3158x monitors the frequency band on the cable input for operator messages. This allows the STB to remain in deep sleep mode while allowing for wake-up on demand by the operator for DVR recording, guide or software updates.
