Abstract: A method includes receiving at a set-top box device first video content associated with a requested channel from a first source. The method includes, in response to receiving the first content, requesting second video content associated with the requested channel from a second source. The method includes, in response to receiving the second video content, determining whether at least one data packet associated with the requested channel was not received based on a comparison of first data packets corresponding to the first video content and second data packets corresponding to the second video content. In response to a determination that at least one data packet was not received, sending a retry request to the first source. The retry request includes an overhead bandwidth factor.

Abstract: A particular method includes measuring port usage data related to each of a plurality of physical ports associated with a link aggregation group. A bandwidth requirement of a requested media stream is estimated and added to a traffic load at each of the plurality of physical ports to produce an estimated total traffic load of each of the plurality of physical ports. When the requested media stream includes non-video data, the requested media stream is sent to a destination device via a physical port that selected in accordance with a static bandwidth allocation. When the requested media stream includes video data, the requested media stream is sent to the destination device via a least loaded physical port that is dynamically identified based on the estimated traffic loads of each of the plurality of physical ports.

Abstract: A method includes receiving data from a set-top box device at an access system via an access network, the data indicating a selection of a channel at the set-top box device, the data including a multicast group address. The method also includes sending copies of video data packets of the channel from the access system for storage in a first-in first-out cache associated with the channel. The method further includes automatically connecting the set-top box device to a multicast stream of the selected channel after a particular number of video data packets are sent to the set-top box device from the cache. The particular number of video data packets corresponds to a time period between communicating successive random access point packets of the channel and is less than a capacity of the cache.
