A method and apparatus for dynamically adjusting power of a transmitter is herein described. A transmitter transmits a pattern to a receiver at a differential voltage. The length of the pattern, in one embodiment, is selected to be a reasonable length training pattern, as not to incur an extremely long training phase.

As a result, a training phase is potentially reduced and power is saved while not sacrificing confidence levels in error rates in the data exchange between the transmitter and receiver.

US08638852B2 Video coding of filter coefficients based on horizontal and vertical symmetry
This disclosure recognizes and exploits the fact that some of the filter coefficients defined at the encoder may possess symmetry relative to other filter coefficients. Accordingly, this disclosure describes techniques in which a first set of the filter coefficients are used to predictively encode a second set of the filter coefficients, thereby exploiting any symmetry between filter coefficients. Rather than communicate all of the filter coefficients to the decoding device, the encoding device may communicate the first set of filter coefficients and difference values associated with the second set of filter coefficients. Using this information, the decoder may be able to reconstruct all of the filter coefficients. In some cases, if exact symmetry is imposed, the need to send the difference values may be eliminated and the decoder may be able to derive the second set of filter coefficients from the first set of filter coefficients.

Virtual justifications or phase data are communicated via a “virtual justification control channel” which may part of the frame overhead. Moreover, there is no need for an actual “virtual justification opportunity” in the frame, because no data is actually sent in conjunction with the virtual justifications.

According to various embodiments, the WAN-edge router is the only multicast enabled element of the network. The remaining elements are not required to be multicast-enabled because their responsibilities are performed by the OpenFlow controller.
