  • Real-time autoleveling system
    Patent number: 7032238
    Abstract: A terminal is coupled to a video distribution network headend, and transmits upstream packets to the headend. Each upstream packet has a transmission power. The terminal receives a downstream packet from the headend, indicating a change in power. The terminal calculates an adjusted transmission power, based on the change in power specified in the downstream packet, and sets the transmission power of the upstream packets to the adjusted transmission power. The headend can be coupled to one or more terminals. The headend receives upstream packets from the terminal. The headend senses a received transmission power of each packet, and calculates a weighted average transmission power based on the received transmission powers. The headend calculates a change in transmission power based on the weighted average and a predetermined set point. The headend transmits a downstream packet to the terminal, indicating the change in power.
