Abstract: Embodiments provide techniques for delivering a paced stream of video data packets. One embodiment includes receiving a data stream of video data packets formatted according to a Society of Motion Picture and Television Engineers (SMPTE) standard. A desired rate of delivery for the video data packets at a gateway device is determined. Embodiments generate a padded data stream by inserting one or more pause frames in between the video data packets in the received data stream, based on the desired rate of delivery. The padded data stream is transmitted across a link to a network switch, to be transmitted to the gateway device.

Abstract: Techniques and apparatus for optimizing scheduling of uplink traffic are provided. One technique includes determining, based on evaluation of a pending interest table (PIT) at an apparatus, at least one portion of an uplink traffic flow from a client device that satisfies one or more conditions for periodicity. A resource for the at least one portion of the uplink traffic flow that satisfies the one or more conditions for periodicity. An indication of the resource allocation is transmitted to the client device.

Abstract: Systems, methods, and computer program products relating to resilient transmission of a media stream over a communication network. A plurality of data packets are received over a communications network. The plurality of data packets relate to a first source video portion transformed using a geometric transform. The geometric transform is configured to modify a location of pixels in the first source video portion such that a plurality of adjacent pixels in the first source video portion are not adjacent after transformation. A received video portion is assembled based on the plurality of data packets. The received video portion is transformed, using an inverse of the geometric transform, to generate a second source video portion. The second source video portion and the first source video portion include a plurality of matching pixels.
