    Abstract: In one embodiment, a method receives a first time from a network device. The first time is derived from a first timing source in a first domain. The method receives a second time in a second domain from a second timing source. A difference time value is calculated between the first time and the second time. The method then sends the difference time value to the network device where the network device uses the difference time value to send a delay value to other computing devices to synchronize timing of the other computing devices in the second domain. The other computing devices are configured to synchronize the respective time using the delay value with mobile network devices to allow timing synchronization between the mobile network devices.

    Abstract: A system and method of inter-coding wherein variable size template matching is employed. A top template, a left template and a top-left template can be defined wherein the width of the top template is equal to the width of the coding block, the height of the left template is equal to the height of the coding block, but the second dimensions (height and width) of the templates are variable. A best match between the current coding block is then identified and the coding block is then encoded using FRUC.

    Abstract: In one embodiment, a method receives a downstream signal and an upstream signal in a same frequency band. The downstream signal and the upstream signal are separated into a first path and a second path. The downstream signal using the first path and the upstream signal using the second path are amplified in an analog domain. The method isolates the downstream signal and the upstream signal from one another and sends the downstream signal downstream to a subscriber device and sends the upstream signal towards a full duplex node.

    Abstract: A statistical multiplexer that distributes the total bandwidth of a multiplexed signal among constituent multiplexed signals. Each multiplexed signal may have an associated priority weight and a complexity. In some embodiments, differences between the priority weights are dampened. In some embodiments the priority weights are used to reallocate complexity among the multiplexed signals.

    Abstract: A method of partitioning in video coding for JVET, comprising representing a JVET coding tree unit as a root node in a quadtree plus binary tree (QTBT) structure that can have quadtree or binary partitioning of the root node and quadtree or binary trees branching from each of the leaf nodes. The partitioning at any depth can use asymmetric binary partitioning to split a child node represented by a leaf node into two child coding units of unequal size, representing the two child coding units as leaf nodes in a binary tree branching from the parent leaf node and coding the child coding units represented by final leaf nodes of the binary tree with JVET. Disclosed is a generalized method of partitioning a block, either square or rectangular, which leads to more flexible block sizes with possible higher coding efficiency.

    Abstract: Techniques for transmitting an optical signal through optical fiber with an improved stimulated Brillouin scattering (SBS) suppression and an improved transmitters signal to noise ratio (SNR) include externally modulating a light beam emitted from a light source with a high frequency signal. The light beam is also modulated externally with an RF information-carrying signal. The high frequency signal is at least twice a highest frequency of the RF signal. The high frequency signal modulating the light source can be split, providing a portion of the split signal to a phase and gain control circuit for adjusting a phase/gain. The output of phase and gain control circuit can be applied to the external modulator to eliminate intensity modulation for SBS suppression improvement. The optical transmitters SNR is further improved by cancelling a beat between SBS suppression modulation tone and out of band distortion spectrum of information bearing RF signal.
