| 20110243223 | MULTIPLEXED VIDEO STREAMING - A plurality of video streams is transmitted over a transmission link. At intervals, one determines for each video stream at each of a plurality of encoder settings, having regard to the amount of data buffered at a receiver for that stream, a bit rate sufficient to transmit the remainder of that stream at that encoder setting such as to avoid buffer underflow at the receiver. One determines also a critical point equal to the earliest time at which that bit rate can be reduced while still avoiding buffer underflow at the receiver. An encoder setting is chosen for each video stream such that the sum of said bit rates required for transmission of the streams does not exceed the capacity of the transmission link. Any surplus capacity of the transmission link is allocated to the stream that has the earliest critical point. | 10-06-2011 |
| 20110292801 | CONTROLLING BANDWIDTH SHARE - There is proposed a modification to the ECN protocol to remove the one-to-one relationship between the network signalling congestion and the sender response to that congestion. The result is to allow a receiver terminal to exhibit some control of bandwidth share relative to other receiver terminals. The idea is to calculate the average CE arrival frequency from received data packets and to set ECE flags at a rate determined as a function of the average CE arrival frequency. Preferably, the function is a multiplier applied to the average CE arrival frequency. The effect of averaging the CE arrival frequency as well as application of a multiplier is a decoupling of the ECE marked ACKs sent by a receiver to the sender, and control of the resulting transmission rate at the sender. | 12-01-2011 |
| 20110296485 | VIDEO STREAMING - A video sequence is to be transmitted at a selectable quality from a server over a network. A network control protocol operates in response to a control parameter to allocate to the server a share of available transmission capacity in proportion to the value of the control parameter. First, one determines a plurality of transmission rate values that are needed over successive time periods of the sequence for successful transmission of the sequence at a reference quality; then the control parameter is set, proportional to the transmission rate value and communicated to the control protocol at corresponding time instants. The sequences can then be transmitted, encoded at a quality from time to time selected in dependence upon the actual transmission capacity made available by the network to the server. | 12-01-2011 |

| 20100234253 | Method for reducing the viscosity of viscous fluids - A viscous fluid, such as heavy crude oil which is too viscous to enable it to be pumped from a flowing phase of a reservoir into and along a pipeline for delivery to a refinery or other storage facility, may be contacted with a formulation to reduce its viscosity. The formulation comprises a polymeric material AA which includes —O— moieties pendent from a polymeric backbone thereof and said material is optionally cross-linked. In one embodiment, the formulation may comprise polyvinyl alcohol. In an alternative embodiment, the formulation may comprise a cross-linked polymeric material, such as cross-linked polyvinyl alcohol. After the viscous composition has been transported to a desired location, it may be separated from the other components. | 09-16-2010 |
| 20100294497 | Recovery of oil - A method of recovering oil from a subterranean formation which includes an association production well involves contacting oil in the formation with a treatment fluid formulation which includes polyvinylalcohol and collecting oil which is being contacted with said treatment fluid formulation by said production well. Use of the polyvinylalcohol, optionally in combination with other materials, facilities recovery of oil from subterranean formation, particularly those involving medium or high viscosity oils. | 11-25-2010 |

| 20110187928 | ELECTRONIC APPLIANCE STATUS NOTIFICATION VIA A HOME ENTERTAINMENT SYSTEM - A method of notifying a user of a status of an electronic appliance is presented. Examples of the electronic appliance may include, but are not limited to, refrigerators, freezers, dishwashers, ovens, and clothes washers and dryers. In the method, an entertainment system device receives a message from the appliance via a communication link, wherein the message indicates the status of the appliance. In response to receiving the message, the device transmits a command to a second device of the entertainment system to select an input of the second device associated with the first device. The first device transmits data indicating the status over a media content interface to the selected input of the second device for presentation to the user. | 08-04-2011 |
