    Abstract: Alternative approaches to the insertion of local commercials and messages into networks feeds are provided. Embodiments include digital commercial insertion for cable operators and others that not only offer more flexibility and features, but may also be significantly cheaper to implement. The actual “insert” of the local commercial or message into the digital program is performed by a standard set top box, with several methods of providing the local commercial to the set top box at the proper insertion time. Another embodiment allows a cable operator to significantly save on equipment in the form of splicers and ad inserters, by allowing easy and dynamic mapping of local commercials to insertion zones.

    Abstract: A method of preparing data streams to facilitate seamless switching between such streams by a switching device to produce an output data stream without any switching artifacts. Bi-directional switching between any plurality of data streams is supported. The data streams are divided into segments, wherein the segments include synchronized starting points and end points. The data rate is increased before an end point of a segment, to create switch gaps between the segments. Increasing the data rate can include increasing a bandwidth of the plurality of data streams, for example by multiplexing, or compressing the data. The present invention can be used, for example, with MPEG or AC-3 encoded audio and MPEG encoded video segments that are multiplexed into MPEG-2 transport streams. Also included are specific methods for preparing MPEG video streams and multiplexing MPEG video with MPEG or AC-3 audio streams to allow a receiver to create seamless transitions between individually encoded segments.

    Abstract: Systems and methods for push-based dynamic bandwidth allocation deliver addressable, advertising content in a digital network. Bandwidth is allocated on a push basis in response to receiving a trigger from a content distribution stream. The trigger contains data indicating an addressable break. A portion of bandwidth is then allocated to an addressable content stream based on the data of the trigger. The addressable content stream is then streamed to a receiver during the addressable break and the receiver is tuned from the broadcast stream to the addressable content stream for the duration of the addressable break. The additional bandwidth is de-allocated at the end of the addressable break.
