This disclosure describes techniques for signaling deblocking filter parameters for a current slice of video data with reduced bitstream overhead. Deblocking filter parameters may be coded in one or more of a picture layer parameter set and a slice header.

Reducing TCP connection establishment time in an overlay network
Applications that run on an overlay network-based managed service achieve high performance gains using a set of TCP optimizations. In a first optimization, a typical single TCP connection between a client and an origin server is broken into preferably three (3) separate TCP connections. These connections are: an edge-to-client connection, an edge-to-edge connection, and edge-to-origin connection. A second optimization replicates TCP state along the connection to increase fault tolerance. In this approach, preferably a given TCP connection is maintained on two servers. When a packet is received by one server, called the primary, its state is updated and then passed to a second server, called the backup. Only when the backup sends an acknowledgement back to the primary can it then send a TCP acknowledgement back to the host that originally sent the packet. Another optimization reduces connection establishment latency. |

Methods and systems for overriding graphics commands
Disclosed are “graphics overrides.” An override accepts a stream of graphics commands as produced by an application and then modifies the stream before it is rendered by the GPU. Different overrides perform different modifications. One override can modify a stream of graphics commands in response to another stream. Overrides can enforce conformity with a visual paradigm and, by being modified, can support a change to that paradigm without requiring the applications to change. Overrides can monitor the entire computing environment and improve the response to that environment of a particular application: For example, an override monitors frames as they are produced by an application. If the application cannot keep up with a fixed frame rate, then the override produces “synthetic” frames to take the place of missing frames. Overrides are not restricted to fixing existing problems. Rather, applications can be developed that depend upon the presence of overrides. |

Antennae system
Embodiments of the invention relate to wireless communications networks, and more specifically to an antenna apparatus for cellular wireless systems. Increasing data capacity of cellular wireless systems places increasing demands on the capacity of the two way connection, known as backhaul, between a cellular base station and a telecommunications network such as the PSTN backhaul, since this is the connection that has to convey the wireless-originating traffic to its destination, often in an entirely different network. Known backhaul links include leased lines, microwave links, optical fiber links or radio resources for relaying backhaul traffic between base stations. The fixed line solutions are expensive to implement and maintain, while the radio solutions antenna configurations that are not ideal for relaying data between base stations. In embodiments of the invention, communication between base stations occurs in a first timeslot by use of a first antenna system and communication between a given base station and a user equipment occurs in a second timeslot using a second antenna system. The benefit of this method is that the first antenna system can be optimized for use in communication between base stations, whereas the second antenna system can be optimized for communication with user equipment which preferably occurs within the area of cellular wireless coverage of the sector served by the second antenna system. |
