Signaling of motion vector difference derivation
A video decoder receives data for a block of pixels to be decoded as a current block of a current picture of a video. When the current block is coded by using inter mode and bi-directional prediction, the video decoder receives a first motion vector difference and determines a second motion vector difference based on a first flag or a second flag. When the first flag is false, the video decoder uses the second flag to determine whether to set the second motion vector difference to be at an opposite value of the first motion vector difference. When the first flag is true, the video decoder sets the second motion vector difference to be zero. The video decoder reconstructs the current block by using motion information based on the first motion vector difference and the second motion vector difference to perform inter prediction. |

Masked packet checksums for more efficient digital communication
A masked packet checksum is utilized to provide error detection and/or error correction for only discrete portions of a packet, to the exclusion of other portions, thereby avoiding retransmission if transmission errors appear only in portions excluded by the masked packet checksum.

Some embodiments of the invention provide a method for implementing a logical network with one or more logical forwarding elements (LFEs), each with multiple logical ports. Each LFE in some embodiments is implemented by several physical forwarding elements (PFEs) operating on several devices. On a host computer executing a particular machine connected to a PFE implementing a particular LFE, the method identifies an address discovery message associating a particular network address (e.g., a layer 2 (L2) address or media access control (MAC) address) of the particular machine with a another network address (e.g., a layer 3 (L3) or an Internet Protocol (IP) address) of the particular machine. The method identifies an LFE logical port associated with the particular machine, stores in an encapsulation header an identifier that identifies this port, encapsulates the address discovery data message with this encapsulation header, and then forwards the encapsulated message to a set of one or more devices implementing the LFE. Each device in the set of devices extracts the logical port identifier from the encapsulation header and stores this logical port identifier for use in processing data messages associated with the particular machine. |

A system and method are provided for processing symbols for transmission. A set of 2K outputs is produced that includes K real components and K imaginary components from K complex symbols. A Fourier transform operation on the 2K outputs produces 2K Fourier transform outputs. Transmit pulse shaping is applied to the 2K Fourier transform outputs.

Dual-mode control of a switch mode power supply
A multi-phase switch-mode power supply to control an output in two possible modes is disclosed. A first mode can be applied for normal load conditions. In the first mode, control is achieved using an error signal based on a difference between an output voltage and a set voltage level. In heavy load conditions a load attempts to draw too more power than the switch-mode power supply can provide. As a result, control of the output voltage is lost and the current of each phase becomes saturated at a limit. When this condition is detected, a second mode can be applied. In the second mode, control is achieved using an error signal based on a difference between an output current and a set current level. The set current level is chosen so that the current of each phase is no longer saturated and control of the output current is maintained. |
