20090041015 | METHOD FOR ALLOCATING DATA PACKET TRANSMISSION AMONG MULTIPLE LINKS OF A NETWORK, AND NETWORK DEVICE AND COMPUTER PROGRAM PRODUCT IMPLEMENTING THE METHOD - A method for intelligently distributing packets of a data stream to multiple links of a network for simultaneous transmission via the multiple links, and for periodically re-allocating the distribution, achieves higher network throughput. The method has particular application for streaming audio-video traffic on a home local area network that has a source device, like a media server PC, and a destination device, like a digital TV. One of the links is assigned as the primary link (PL), and another link is assigned as a backup link (BL). Periodically a signal is sent from the source device over each link to the destination device and the round-trip travel time (RTT) for the signal and response for each link is measured. The RTT for a link is a good measure of the current end-to-end link status and generally will change during the time that the data stream is being transmitted as a result of certain events, such as traffic load and interference. The RTT on the PL (RTT-PL) and the RTT on the BL (RTT-BL) are used to adjust the allocation of packets simultaneously transmitted on the links. | 02-12-2009 |

The prediction residuals are usually smaller when the video is less complex and more predictable. Scales of prediction residuals also depend on encoding configurations, for example, I pictures usually have larger prediction residuals than P and B pictures even when the contents are very similar and thus have similar perceived content complexity. To more closely reflect the content complexity, alignment scaling factors are estimated for different encoding configurations. Based on the energy of prediction residuals and alignment scaling factors, an overall content unpredictability parameter can be estimated to compute a compression distortion factor for the video. The compression distortion factor, combined with slicing and freezing distortion factors, can be used to estimate a video quality metric for the video. | 08-06-2015 |
20150373324 | Method And Apparatus For Context-Based Video Quality Assessment - Spatial distortion (i.e., when a frame is viewed independently of other frames in a video sequence) may be quite different from temporal distortion (i.e., when frames are viewed continuously). To estimate temporal distortion, a sliding window approach is used. Specifically, multiple sliding windows around a current frame are considered. Within each sliding window, a large distortion density is calculated and a sliding window with the highest large distortion density is selected. A distance between the current frame and the closest frame with large distortion in the selected window is calculated. Subsequently, the temporal distortion is estimated as a function of the highest large distortion ratio, the spatial distortion for the current frame, and the distance. In another embodiment, a median of spatial distortion values is calculated for each sliding window and the maximum of median spatial distortion values is used to estimate the temporal distortion. | 12-24-2015 |

A load balancer module on the server node makes the decision on whether to accept or reject the connection based on one or more metrics indicating a respective server's current load. If the module accepts the connection request, a connection is established between the server and the client. Otherwise, the load balancer nodes may select another server node and try again. The connections established between clients and servers pass through the load balancer nodes, but are not terminated at the load balancer nodes. | 10-16-2014 |
