  • Patent number: 8598978
    Abstract: A radio-frequency (RF) load control system includes both two-way and one-way (e.g., transmit-only) remote control devices, and provides a simple, reliable process for configuring the one-way devices into the system. The one-way device may be programmed to operate at one of a predetermined number of radio frequencies as part of a frequency-selection procedure, during which, the one-way device transmits a test command to a signal repeater of the system. If the test command is transmitted at the same frequency as the repeater, the repeater emits an audible beep to inform the user that the remote control is transmitting at the appropriate frequency. To associate the two-way devices with the system, the signal repeater streams an “enter address mode” command. To allow the one-way device to be associated with the system, the signal repeater pauses the transmission of the enter address mode command to allow the one-way device to transmit an activation request message to the signal repeater.

  • Patent number: 8537679
    Abstract: A method for load balancing IPTV channels is described. In one embodiment of the invention, a first Provider Edge (PE) network element of a label switched network, coupled with a second PE network element over multiple member links of an aggregate link, receives IPTV packets. For each IPTV packet received, the first PE network determines layer 3 information of the IPTV packet, and generates one or more channel load balancing keys based on the layer 3 information. The PE network element generates a hash value from the channel load balancing keys and determines which one of multiple member links to transmit the IPTV packet on based on the hash value, and transmits the IPTV packet to the second PE network element on the determined member link. Other methods and apparatuses are also described.
