20140118615 | MODIFICATION OF DELIVERY OF VIDEO STREAM TO WIRELESS DEVICE BASED UPON POSITION/MOTION OF WIRELESS DEVICE - Processing video data for delivery to a remote wireless includes receiving video data from a video source and receiving position and motion information regarding the remote wireless device. Operation also includes, based upon the position and motion information regarding the remote wireless device, determining an anticipated Quality of Service (QoS) available for servicing of transmissions to the remote wireless device and determining video processing parameters based upon the video data and the anticipated QoS. Operation further includes processing the video data based upon the video processing parameters to produce an output video stream and transmitting the output video stream for delivery to the remote wireless device. Operation may also/alternatively include altering wireless transmission parameters of a transport stream servicing delivery of the video data to alter the anticipated QoS. | 05-01-2014 |
20140211803 | BRIDGE ROUTING MODULE - A bridge routing module can be incorporated into a closed network fabric, such as a vehicular network. The bridge routing module includes an interface circuit to be coupled to other elements of the closed network fabric, for example other bridge routing modules or switch modules. The bridge routing module includes memory to store information associating packet content types with packet routing parameters, among other things. A processing module included in the bridge routing module analyzes packets to identify the type of content carried by the packets, and determines packet routing parameters based on the packet's content type. Ingress and egress of the packet are controlled in accordance with the packet routing parameters determined by the processing module. | 07-31-2014 |
20150043659 | VIDEO PROCESSING SYSTEM AND TRANSCODER FOR USE WITH LAYERED VIDEO CODING AND METHODS FOR USE THEREWITH - A video processing system includes a video transcoder that receives a independent video layer stream and a first dependent video layer stream that requires the independent video layer for decoding, the video transcoder generating a transcoded video signal based at least one of the independent video stream and the dependent video layer stream. | 02-12-2015 |
