Abstract: Different data communication architectures deliver a wide variety of content, including audio and video content, to consumers. The architectures employ channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architectures distribute video programming in the form of MPEG2 TS packets, flagged by marker packets, in a round-robin manner across the communication channels. Channel bonding synchronization information may be present in packets defined above the data-link layer or added to fields within data-link layer frames.

Abstract: A data communication architecture delivers a wide variety of content, including audio and video content, to consumers. The architecture employs channel bonding to deliver more bandwidth than any single communication channel can carry. The architecture includes intermediate network devices that may receive content and send content using different groups of communication channels. The network device may process content received across a first set of communication channels for transmission across a second set of communication channels different from the first set. Such processing may preserve a program order of the content during delivery to a destination device.

Abstract: A data communication architecture delivers a wide variety of content, including audio and video content, to consumers. The architecture employs channel bonding to deliver more bandwidth than any single communication channel can carry. In some implementations, the communication architecture communicates content according to an initial bonding configuration. The communication architecture may adjust the bonding configuration to adapt to bonding environment changes affecting the communication capabilities or requirements associated with transmitting the content.

Abstract: Certain aspects of a method and system for adaptive temporal interpolation filtering for motion compensation may include computing a plurality of weights for adaptively adjusting one or more parameters of a plurality of linear filters utilized for motion compensation. One or more motion compensated output pictures may be generated based on vector median filtering a plurality of linear filtered output pictures generated by the plurality of linear filters. In instances where two frames are utilized for motion estimation of a video sequence, a motion compensated picture of a previous frame and a motion compensated picture of a current frame may be combined to adaptively compute the subsequent weights. In instances where three or more frames are utilized for motion estimation of a video sequence, the generated one or more motion compensated output pictures may be combined with an extracted desired picture from the video sequence to adaptively compute the subsequent weights.

Abstract: Aspects of a method and system for hierarchical motion estimation with multi-layer sub-pixel accuracy and motion vector smoothing are presented. Aspects of the system may include hierarchical motion vector computation that enables motion vectors to be computed at each level in the hierarchy based on a distinct pixel resolution level. A smoothing algorithm may be utilized to suppress spurious motion vector generation. The motion vectors computed at one level in the hierarchy may be utilized when computing motion vectors in a subsequent level. A bias value may be computed for each motion vector that provides an evaluation metric that may enable determination of whether the computed motion vector is to be utilized to enable generation of the interpolated image frame.
