Method and apparatus for encoding and transmitting at least a spatial part of a video sequence
When encoding and transmitting video data comprising regions of interest, different usages of the regions of interest implicate different kinds of combination of region of interest at decoding. By studying the different impacts of the encoding mechanisms depending on other set of tiles data on the different kind of combination, it is possible to define a plurality of tile set coding dependency levels. Each tile set coding dependency level is linked to a set of constraints on encoding. These set of constraints have different impacts on the possibilities allowed when combining the different regions of interest. It is therefore possible, based on a desired usage, to select an encoding with minimal restrictions, as defined by a given tile coding dependency level, compatible with the desired usage. Accordingly, the encoding efficiency is improved, for a given usage, compared to a solution where a complete tile independency solution is used. |

By doing so, not only can the service provider network and the partner network take advantage of each other's network resources, but they can also give each other's customers broader network reach into regions that are not typically serviced by their own networks. The service provider network may effectively accomplish this by providing a limited view of the service provider network to the partner network, or vice versa, so that traffic and data can flow between the networks without each network having to be fully aware of each other's entire network topologies. |

Cross-product detection method for a narrowband signal under a wide range of carrier frequency offset (CFO) using multiple frequency bins
A synchronizer generates cross-products of In-phase (I) and Quadrature (Q) samples and stores the sign bits for the sine and cosine cross-products.

A PIN diode has an anode spaced away from a central region of a top surface of a substrate, such that the anode is in a corner or at a side edge of the top surface. Alternatively, the PIN diode has an anode surrounded by a shield layer. The PIN diode reduces unwanted parasitic capacitance to increase the reverse isolation of RF switches and to reduce the diffusion capacitance to increase the f3dB frequency specification of amplifier circuits. The PIN diode dramatically reduces the values of both parasitic and diffusion capacitances, which enables its application in switches and amplifiers under a wide variety of bias conditions including reverse, low-moderate forward, and large forward-bias; which enables bonding to a much larger metal area than the active electrode, with negligible increase in the parasitic capacitance; and which enables reliable wire-bonding by presenting a highly planar metal surface. |

Transistor gate trench engineering to decrease capacitance and resistance
Techniques are disclosed for transistor gate trench engineering to decrease capacitance and resistance. Sidewall spacers, sometimes referred to as gate spacers, or more generally, spacers, may be formed on either side of a transistor gate to help lower the gate-source/drain capacitance. Such spacers can define a gate trench after dummy gate materials are removed from between the spacers to form the gate trench region during a replacement gate process, for example. In some cases, to reduce resistance inside the gate trench region, techniques can be performed to form a multilayer gate or gate electrode, where the multilayer gate includes a first metal and a second metal above the first metal, where the second metal includes lower electrical resistivity properties than the first metal. In some cases, to reduce capacitance inside a transistor gate trench, techniques can be performed to form low-k dielectric material on the gate trench sidewalls. |
