Abstract: According to one exemplary embodiment, a circuit board for reducing dielectric loss, conductor loss, and insertion loss includes a pair of transmission lines. The pair of transmission lines has sufficient thickness to cause substantial broadside electromagnetic coupling between the pair of transmission lines, where the pair of transmission lines is sufficiently separated from a ground plane of the circuit board so as to cause negligible electromagnetic coupling to the ground plane relative to the substantial broadside electromagnetic coupling. The pair of transmission lines thereby reduce dielectric loss, conductor loss, and insertion loss for signals traversing through the transmission line pair. The pair of transmission lines can be separated from the ground plane by, for example, at least 50.0 mils.

Abstract: Entropy coder supporting selective employment of syntax and context adaptation. In video coding, different entropy coding is selectively and adaptively employed based on local and/or remote consideration(s). For example, certain entropy coding may be context adaptive while other entropy coding may be non-context adaptive, and may operate in accordance with syntax or without syntax. Selective adaptation between context adaptive entropy coding and non-context adaptive entropy coding, as well as those which operate using syntax or without syntax may be made based on one or more local and/or remote characteristic(s). Transitioning between the various end to end configurations midstream can occur upon reference frame transitions with appropriate header information leadoff in a given bitstream. A given device (e.g., encoder or transcoder) may be implemented to transition independently, in cooperation with, or under the direction/coordination with one or more other devices within the communication system.
